From d29a4d4256d5a81604a048ec5936a3044d6c1df4 Mon Sep 17 00:00:00 2001 From: Tajudeen Date: Sun, 31 May 2026 16:07:45 +0100 Subject: [PATCH 01/80] chore(dev): fix dev-build launch + add CDP smoke harness and test-status doc The dev build could not launch from a terminal inside a VS Code-family editor (VS Code/Cursor/CortexIDE): the inherited ELECTRON_RUN_AS_NODE=1 makes the Electron binary run as plain Node, so out/main.js dies with "module 'electron' does not provide an export named 'Menu'". - scripts/code.sh: unset ELECTRON_RUN_AS_NODE before launching. - test/cortexide-smoke/: launch-dev.sh (launches the .build/electron app with a --remote-debugging-port, stripping the bad env var, using a persistent profile) + cdp-smoke.mjs (attaches over CDP with Playwright and asserts core + CortexIDE surfaces render) + README + .gitignore. Verified by hand: cdp-smoke.mjs reports 11/11 checks pass on macOS arm64; the workbench, CortexIDE chat sidebar and the CortexIDE settings pane all render. - firstRunValidation.ts: the first-run self-test probed a non-existent command id 'cortexide.quickAction' and therefore always warned; probe the real void.* Quick Action ids instead. Also drop non-ASCII glyphs from log strings (hygiene). - CORTEXIDE-TEST-STATUS.md: living doc of what is verified working vs broken. Records the launch gotcha and a measured finding: the ext-host / json-language-features restart noise occurs only on a COLD profile (run 1: startFailed x16, json x87) and clears on the WARM second run against the same profile (both x0, ext host starts once) - a first-launch init-timeout artifact, not a steady-state bug.

The validator, so the model gets a clear error before the request. 2. The impl boundary, so redirect re-entry (callTool.browse_url skips the validator) and any future internal caller can't bypass it. Covers literal hostname bans only. DNS-resolution bypasses (a public-looking hostname that resolves to a private IP) are not caught here — that needs async preflight + IPs-of-redirect checking and is queued as a follow-up. Includes unit tests covering loopback, private ranges, link-local (incl. cloud metadata), IPv6 forms, IPv4-mapped IPv6, and boundary cases just outside the blocked CIDRs.

charset=UTF-8 Content-Transfer-Encoding: 8bit buildFreeTierLadder dropped providers at their RPD or RPM limit but NOT their tokens-per-minute (TPM) limit, so a provider whose per-minute token budget was used up (e.g. groq, tpm=6000) stayed on the ladder and the very next call earned an avoidable 429 — exactly the stall that undermines "free models out of the box". Added the missing `remaining.tpm <= 0` filter alongside the existing RPD/RPM ones. Regression test added (freeTierLadder: 9 -> 10 passing).

It was both meaningless (tested a copy) and flaky (monkeypatched the shared fileService without restoring it + an undisposed TestLanguageConfigurationService), yielding 2/3 or 6/5 across runs. Rewrote it to instantiate the real `ApplyEngineV2` via createInstance, wired with real ModelService / TextModelResolverService / InMemoryTestFileService and small recording mocks for the rollback/stash/audit collaborators. Exported the `ApplyEngineV2` class so it can be constructed in tests. 7 deterministic, leak-free tests (verified stable across repeated runs): create writes content; edit full rewrite; path-safety rejects out-of-workspace (write_failure, file not created); atomicity (a write failure during apply fails the transaction, creates a rollback snapshot, attempts restore, and does NOT discard); deterministic ordering (same result regardless of input order); a successful apply records an ok=true audit event and discards its snapshot. base-mismatch is intentionally NOT unit-tested and the reason is documented inline: the engine reads content through the cached text model for both the base signature and the re-verification, so it cannot be triggered by external disk mutation (an earlier readFile-override attempt silently did not run). It is covered indirectly by the verification/rollback choreography. applyEngineV2: flaky 2/3 -> 7/0. This was the last open suite.

The wrong theme path made the whole suite fail to LOAD (ERR_MODULE_NOT_FOUND, counted as 0/0 — which masked the real status); once it loaded, every create/edit test threw "Cannot read properties of undefined (reading 'asCanonicalUri')" because TextModelResolverService.createModelReference needs IUriIdentityService. Fixed the import path and registered UriIdentityService(fileService). applyEngineV2 now loads and passes 7/7 deterministically (verified declared==passing, stable across repeated runs).

Earlier "green" readings were actually the suite silently failing to LOAD (wrong testThemeService import path → counted as 0/0). Proper fix: the engine is the unit under test; ITextModelService is a collaborator, so mock it. Replaced the ModelService/TextModelResolverService/UriIdentity/Language/Theme scaffold with a tiny in-memory FakeTextModelService (per-uri model cache backed by the file service).

Add a pure, unit-tested describeFreeTierExhaustion() (reuses buildFreeTierLadder so its verdict can't disagree with the router): detects full exhaustion and recommends a configured local model, else a BYO key, else adding one. Exposed via ITaskAwareModelRouter.getFreeTierExhaustion() and used in chatThreadService's two rate-limit/fallback error paths (message-only; no control-flow change). Status bar free-tier widget now shows the currently-active rung (what the router would pick now) instead of always the top-quality provider, plus a clear all-exhausted badge + hint. freeTierExhaustion 9/9; common suites 79/0; tsc clean for touched files.

this moves the same guarantee to the single 429 chokepoint so EVERY feature (apply, ctrl+k, commit, codeReview, autocomplete, chat) benefits. In sendLLMMessageService's free-tier onError wrapper, after markExhausted on a rate-limit error, if describeFreeTierExhaustion reports the whole ladder is exhausted, rewrite the error to the actionable message (offer local/BYO) before calling the caller's onError. Gated on exhausted-only so chat's per-provider fallover loop (which keys off the raw 429 text) is preserved while other free providers still have quota. No provider-switching here (transparent re-dispatch is the tracked follow-up). tsc clean for touched files.

Root cause: agent-default + 'Use tools for EVERY action. Never answer from memory alone.' + the whole tool catalog injected even for the 3B model. Fix (keep agent-default; local/weak models first, per product decision): per-turn _effectiveChatModeForTurn() returns 'normal' (zero tools) for a turn detected as a trivial general-knowledge question on a LOCAL model, so it answers directly instead of entering the loop. The user's Agent mode is unchanged in the UI; the effective mode flows to tool-gating + system prompt + send call consistently (and the plan branch). Backed by a pure, unit-tested isTriviaQuestion() (simpleQuestionGate, 10/10) that is conservative: attachments or any workspace/action/codebase signal keep full tools (e.g. 'what is failing in my build?' is NOT gated). Also: softened the local tool mandate (prompts.ts:752) to answer general-knowledge directly; lowered the agent iteration cap to 30 for local models (vs 100) with an actionable 'try Ask/Normal mode' message; DRY'd the old inline _detectSimpleQuestion onto the shared helper. tsc clean; 96 common unit tests green.

Two changes, gated to local models: 1) Curated tool-set: availableTools(chatMode, mcpTools, {isLocal}) now intersects with COMPACT_LOCAL_TOOLSET (read/search/edit + diagnostics + todo + attempt_completion + run_command) and drops MCP for local models. Threaded through the local system prompt's XML tool catalog (chat_systemMessage_local -> systemToolsXMLPrompt). A local model is no longer TOLD about terminal/MCP/web/refactor tools, so it stops hallucinating them. compactLocalToolset 7/7 asserts the set is valid + excludes persistent-terminal/web. (Native-format builders + the XML parser keep the full set for now -> follow-up; the just-shipped graceful handling covers any rare hallucinated dropped tool.) 2) Consecutive-error cap: count tool errors in a row (reset on any success); after 3 (local) / 6 (cloud), stop with an actionable 'try Ask/Normal mode' assistant message instead of thrashing up to the iteration cap. Resets on success so healthy multi-step runs are unaffected. tsc clean for touched files; 103 common unit tests green.

Root cause was a chain: the no-scoring Auto fallback returned ollama's first-listed model, and on the scoring path the 3B-vs-7B delta was a ~1.75-pt coin-flip easily flipped by the learned-score blend. - resolveAutoModelSelection: for LOCAL providers pick the most capable installed coder (pickBestCoderModelName) instead of the first non-hidden model. Closes the dominant no-scoring bypass. Single-model users still get their one model. - modelRouter code + codebase-question branches: add smallLocalModelCodePenalty so a sub-7B local coder is decisively demoted below a 7B+ coder on code tasks (delta > the learned-score swing) -- never excluded, only demoted. - ollamaRecommendedModels: lead with qwen2.5-coder:7b (was :1.5b, below the floor). New pure helpers pickBestCoderModelName + smallLocalModelCodePenalty (16/16 tests). VERIFIED LIVE on a pristine profile: Auto now selects qwen2.5-coder:latest (7B) and creates fib.py with content, where it previously picked the 3B and failed.

Broaden the trigger from "no provider" to "no capable setup": show Express unless the user already has a configured cloud provider OR a local coder big enough for agentic work (isCapableLocalCoder >= 7B / flagship tag). When it fires with ollama running, the existing Express path pulls qwen2.5-coder:7b. Selection stays on Auto so the FIM-aware router picks per task (we deliberately do NOT pin an explicit model, which would bypass per-task routing). New pure helper isCapableLocalCoder (19/19 in codingModelScore.test.ts). Verified live (capable coder present): Express correctly hidden, no React error, Chat on Auto. The no-capable-coder path reuses the unchanged Express auto-pull machinery.

In an agent tool-loop the system prompt + tool catalog + accumulating results blow past 4096 fast, truncating the model's own earlier context (incl. "you already wrote fib.py") — which can make even a capable model loop or fumble. Verified: /v1 ignores num_ctx, native /api/chat honors options.num_ctx. Add sendOllamaChat (Ollama SDK, native /api/chat) and reroute the ollama chat dispatch to it. It sets options.num_ctx to the model's advertised context window (clamped to 16384 to avoid KV-cache OOM on modest GPUs; floored at 4096 = never worse). Ollama returns no structured tool_calls (text only), so the native path flattens array message content to strings (ollama requires string content), applies the reasoning wrapper, and applies extractXMLToolsWrapper so XML tool calls execute (JSON ones are still parsed downstream); skips the OpenAI-only org-verification retry. First-token + rolling-stall timeouts preserved. Verified live (fresh profile, qwen2.5-coder / deepseek-coder via Auto): ollama ps shows CONTEXT 16384 (was 4096) and the agent creates fib.py WITH content.

Add an optional AgentRunContext { chatModeOverride, isSubagent, parentThreadId } to the loop: a normal turn omits it and reads globals exactly as before (verified no behavior change, tsc clean); a sub-agent will pass one so the SAME loop runs in an isolated context. Foundational no-op refactor that unblocks run_subagent (R2), custom agents, parallel and background agents. See docs/GAP-ANALYSIS.md.

New AGENT-ONLY builtin tool run_subagent { description, prompt, agentType? } that delegates a scoped task to a child agent running the SAME loop in an isolated context: - Dispatched inside chatThreadService._runToolCall (it needs the chat service to spawn a child loop; toolsService has no IChatThreadService dep). callTool has a throwing stub only to satisfy the exhaustive type — never reached. - _runSubagent spawns a hidden child thread (newThreadObject, not in openTabs), seeds it with ONLY the prompt (clean context), re-enters _runChatAgent with runCtx { chatModeOverride:'agent', isSubagent, parentThreadId } (the R1 keystone), then returns ONLY the child's attempt_completion summary to the parent. The parent never sees the child's intermediate tool calls. - No nesting: a sub-agent thread is tracked in _subagentThreadIds and run_subagent is rejected (recoverable) when invoked from a child. - Curated OUT of COMPACT_LOCAL_TOOLSET: weak/local models don't spawn sub-agents (so this is effectively a capable/cloud-model feature, as intended). Additive + does not touch existing chat flows (normal chat unchanged; local models never see the tool). tsc clean end-to-end. NOT yet live-verified end-to-end: in CDP testing Auto selected the 1B deepseek-coder:latest (the rank-6 size tie) which can't drive a new complex tool, and run_subagent is curated out for local. Needs a capable/cloud model to confirm the model actually calling it; the child-thread lifecycle reuses proven thread primitives (newThreadObject/_addMessageToThread/_runChatAgent).

New cortexideAgentsService (mirrors cortexideRulesService: reads + watches .cortexide/agents/*.md). Each file = optional `key: value` frontmatter (name, description, tools, model) + a Markdown body that is the agent's system prompt. parseCustomAgentFile is pure + unit-tested (5/5). Wired into _runSubagent: when run_subagent is called with an agentType matching a custom agent, the agent's system prompt is prepended to the child's seed so it takes on the specialized role. v1 scope: system-prompt role only. Follow-ups (docs/GAP-ANALYSIS.md): true system-message slot, per-agent tool restriction + model pin via AgentRunContext, and orchestrator discoverability. Like R2, needs a capable model to call run_subagent, so this is tsc-clean + parser-tested but not E2E live-verified.

Both caches that could poison a child with a normal-turn message are keyed on it: the cloud system-message cache (_generateChatMessagesSystemMessage) and the message-prep cache (_getMessagePrepCacheKey). - Model pin: resolveAgentModelSelection (pure, 5/5 tests) maps a custom agent's `model` string ("provider:model" with colon-in-tag handling, or a bare name via provider-priority scan) to an installed ModelSelection; _runSubagent uses it for the child (+ recomputed options), else inherits the parent's. - AgentRunContext gains systemPromptOverride; _runSubagent stops prepending the agent prompt to the seed (it's now a system message). All new params optional => normal chat is byte-identical (availableTools "default == non-local" canary still green). tsc clean. allowedTools tool restriction (R4.2) deferred — touches the dispatch gate + native/XML paths. Like R2, the run_subagent path needs a capable model to E2E-verify.

Threaded through systemToolsXMLPrompt -> chat_systemMessage (+ _local) -> prepareLLMChatMessages -> AgentRunContext, and folded into both system-message caches. attempt_completion is ALWAYS kept so a restricted sub-agent can still signal completion. - DISPATCH (authoritative): _runToolCall blocks any tool outside the agent's allowlist via a per-thread map (_allowedToolsByThread, set in _runSubagent), covering builtin + MCP, with the same recoverable-throw pattern as the curation / no-nesting guards. attempt_completion always allowed. availableTools allowedToolNames: 6 new tests (intersect, always-keep attempt_completion, empty=>only completion, only-removes-with-isLocal, MCP filter, backward-compat canary) — 13/13. tsc clean; normal chat byte-identical (params optional).

Safe because each child is forced to a READ-ONLY toolset (READ_ONLY_SUBAGENT_TOOLS: read/search/diagnostics/LSP-nav + attempt_completion — no edits, no run_command, no terminals), so Promise.all can't cause file-system collisions (parallel EDITING still needs worktree isolation, deferred). - _runSubagent gains a readOnly flag → forces READ_ONLY_SUBAGENT_TOOLS as the child's allowlist (enforced by R4.2's prompt intersect + dispatch gate). - _runParallelSubagents Promise.all's read-only children; a child that throws degrades to a per-task error entry (doesn't fail the batch). Returns every child's summary. No-nesting enforced (curated out of COMPACT_LOCAL_TOOLSET, AGENT_ONLY, and rejected on a sub-agent thread). - abort-propagation already covers the children (each registered under the parent). tsc clean; availableTools canary still green (13/13). Like the rest of the track, needs a capable model to call the tool for E2E.

CRITICAL leak: a finished sub-agent's hidden child thread was never removed from state.allThreads, and its per-thread caches (_fileReadCache(+LRU), _planCache, _pendingStreamStateUpdates, _suppressPlanOnceByThread, streamState) were never cleared — every run_subagent call leaked a full thread + caches for the window's lifetime. Add _disposeSubagentThreadState and call it from a finally so it also runs on the error path. The summary is now extracted INSIDE the try (before disposal); behaviour is otherwise identical. 2. HIGH cache poisoning: _getMessagePrepCacheKey keyed the sub-agent system prompt on only length + first 60 chars, so two custom agents sharing that prefix+length collided and got each other's prepared messages. Key on the full prompt, matching the cloud system-message cache key. 3. LOW leak: _childThreadsByParent kept an empty Set per parent forever; delete it once the last child finishes. 4. TYPE error (hidden by the never-finishing tsc): the run_subagent param descriptor used `agentType`, but builtinTools snake_cases param keys, so the advertised name must be `agent_type` (validateParams already accepts both).

With the new enableAutoCompaction setting (default OFF), when a run's prepared-prompt tokens cross ~75% of the context window the agent sends a COMPACTED view — the original request + recent messages, with the middle replaced by a marker — so it keeps going. NON-DESTRUCTIVE by design: only the messages sent to the LLM this turn are windowed; the stored thread keeps full history, so checkpoints, the UI, and persistence are untouched. Best-effort: any failure falls back to the full prepared messages. Only runs in agent/plan mode, so normal chat is byte-identical. Pure decision logic (shouldCompactConversation / selectCompactionWindow) extracted to compactionPolicy.ts, 14/14 unit tests. (LLM-summarization compaction is a future enhancement; v1 is a safe, provider-agnostic sliding window since LLMChatMessage is provider-specific.)

The "hidden runner" is a new electron-main IPC channel (HooksRunnerChannel) that spawns the command with shell:false (argv array -> no injection), stdio:'ignore' (quiet), and a per-hook timeout — unlike the visible terminal tool. Pieces: hooksServiceTypes (types + pure, tolerant parseHooksConfigFile, 7/7 tests); CortexideHooksService (browser: loads/watches the config, fires hooks fire-and-forget via the channel); HooksRunnerChannel (electron-main) registered in app.ts; pre/post- tool + agent-stop fire points in chatThreadService. Gated by enableLifecycleHooks (default off) AND presence of a matching hook, so it's a pure no-op when unused — normal chat and the agent loop are byte-identical. Hooks are fire-and-forget (can't block/cancel a tool in v1) and failures are silent (never break the agent).

New IBackgroundAgentsService is a pure observable registry (no chatThreadService dep, no DI cycle); chatThreadService.startBackgroundAgent spawns a hidden thread, runs the normal agent loop async, and updates the run's status (running -> completed/ error/cancelled) with start/finish notifications. The "CortexIDE: Start a Background Agent" command prompts for a task; the RunningAgentsPanel (sidebar, shown only when agents exist) lists them with cancel + clear-finished. Background agents use the normal approval flow (no silent bypass) and their hidden threads are in-memory only. Purely additive — the panel returns null when empty, so normal chat is unchanged.

Adds a tiny async serializer (createSerializer, 4/4 unit tests) and routes the file-edit tools (edit_file/rewrite_file/multi_edit/create/delete) through a shared _editSerializer in chatThreadService, so concurrent edits apply strictly one-at-a-time. No-op for a single agent editing sequentially (the chain is idle -> runs immediately). This is the SAFE foundation for parallel editing. True worktree branch-isolation (each parallel sub-agent edits its own git worktree, then merge) remains XL/future: it needs a per-agent workspace-root override threaded through the stateless tool path-resolution (validateURI), the edit-apply path, and terminal cwd — invasive to the core path contract.

From e87585d1017835bfb956bbffcb3ca73dffcd8a2a Mon Sep 17 00:00:00 2001 From: Tajudeen Date: Thu, 4 Jun 2026 23:32:16 +0100 Subject: [PATCH 75/80] feat(agent): worktree workspaceRootOverride thread for parallel-edit phase 2 (step 2) Thread a per-sub-agent git-worktree root through the tool-validation path so a sub-agent's file tools resolve against, and are fail-closed confined to, the worktree instead of the workspace. Load-bearing piece for parallel-edit phase 2. - common/worktreePathOverride.ts (new): resolveWorktreeRootedURI re-roots a model path to a worktree and fail-closed rejects any escape (normalizePath THEN isEqualOrParent). Handles relative / already-in-root absolute / coerced fake-root absolute / file:// (no authority); rejects other schemes/authorities. 15/15 tests. - toolsService.ts: ValidateParamsOpts type; validateURI/validateOptionalURI gain a worktree-root param; all 18 file-touching validators forward opts.workspaceRootOverride. No-override path is byte-identical. - chatThreadService.ts: AgentRunContext.workspaceRootOverride; thread-local _workspaceRootOverrideByThread set in _runChatAgent, cleared in _runSubagent finally, read in _runToolCall. Keyed by threadId (not runCtx) so it survives the approval-resume re-entry that drops runCtx (mirrors allowedToolNames). Adversarial review caught + fixed: (CRITICAL) isEqualOrParent is a raw path-prefix test that does not collapse "..", so a file:// URI with ".." escaped the worktree; fixed by normalizing every branch before the guard + rejecting non-file/authority URIs. (MEDIUM) a genuine in-worktree absolute path was double-rooted; fixed with an already-in-root short-circuit. Re-verified sound across 50+ adversarial inputs. Not yet live: no caller sets the override (that is step 3, run_parallel_edit_subagents). Roadmap re-scoped accordingly.

THE BIG ONE — automatic model failover (chatThreadService.ts, common/routing/modelFailover.ts): - All cross-provider failover was fenced behind `if (isAutoMode)` and only reachable from the transport-error branch, so an explicitly-picked (or onboarding-pinned) local model that failed — or stalled past the tool-error / iteration caps — just errored out. Extracted a pure, tested ranking helper + a tryEscalateModel closure wired into ALL THREE terminal exits, independent of Auto mode: on a hard error, repeated tool failures, or the step-limit, escalate the same task to the best OTHER configured model (prefers a capable cloud model). - Honors a new default-on enableModelFallback setting AND routingPolicy 'local-only' (never leaks local-only data to the cloud). Sub-agents never silently switch model. - Free-tier exhaustion now auto-switches to a configured BYO cloud key (e.g. Pollinations) first, then local — instead of a dead-end "switch manually" message. avoidFreeTier deprioritizes the throttled free providers so it lands on the working key. Why simple tasks failed: - Native cloud models were force-fed XML tool instructions that only get parsed for non-native models, so the action was silently dropped; native models now get a clean native-tool prompt while local keeps XML (convertToLLMMessageService.ts). - Tool-name synonyms (create_file->create_file_or_folder, run->run_command, ...) were only canonicalized on the JSON-text path; native tool_calls threw "No tool named ...". Now canonicalized where the tool call is finalized. - isLocalModel / caps / tool-curation were computed from the unresolved 'auto' selection; now derived from the resolved model and recomputed on every model switch. - ollama history now uses the XML/text tool format consistently (it never returns native tool_calls), so turn 2+ of the loop keeps prior tool context. Model catalog / "all models work": - Unrecognized models got a crippling 4096-ctx / no-native-tools default; now a safe family-aware default (provider-appropriate specialToolFormat + sane ctx) so a brand-new cloud model works agentically out of the box (modelCapabilities.ts). - Implemented real online /models fetchers for OpenAI/Groq/xAI/DeepSeek/Mistral/Anthropic/ Gemini (+ a chat-model filter), auto-refresh on launch, and an honest "found N models" message instead of the stub's false "refreshed!" (remoteCatalogService.ts, refreshModelService.ts, Settings.tsx). Reliability / routing: - Remote streaming now has a 30s first-token timeout (was local-only) so a stalled cloud connection fails fast and feeds the failover (sendLLMMessage.impl.ts). - Router prefers a capable cloud model over local on code/agentic tasks when one is configured, respecting Local-First / local-only (modelRouter.ts). - Fixed the synthesized create-file fallback picking the word "file" as the filename. Verification: tsgo clean; 14/14 new modelFailover unit tests (incl. the free-tier->BYO scenario); all changed files bundle-clean; transpile + React build succeed; app boots and renders (CDP smoke 11/11 on this build). Adds a failover-e2e.mjs harness.

All three fixed; verified end-to-end: free-tier exhausted -> auto-failover -> pollinations/claude -> task executes. 1. KEYSTONE (pre-existing): the LLM onError handler sets streamState.isRunning = undefined (to unstick the submit button), and the very next line — a guard meant to detect "a newer thread took over" (`if (isRunning !== 'LLM') return`) — saw that undefined and returned BEFORE the entire llmError branch. This made ALL error handling unreachable on every error: the existing auto-mode fallback AND the new model-failover. The guard now only bails for non-error results (`llmRes.type !== 'llmError' && isRunning !== 'LLM'`), so error handling always runs. (Also hardened the terminal error block to read llmInfo defensively, since onError has already cleared it by the time we get there.) 2. Plan generation ran a separate sendLLMMessage BEFORE the agent loop for complex tasks; its onError dead-ended (showed the error, rejected) with no failover. It now resolves with no plan and falls through to direct execution, where the failover runs. 3. The agent loop's rate-limit detector only matched 429/"rate limit"/tpm, missing Google's "quota exceeded" / RESOURCE_EXHAUSTED — so avoidFreeTier never engaged for the gemini free tier. Now detects quota/resource_exhausted (matching the service layer). Net: a failing/throttled model now reliably hands off to the next configured model (BYO cloud key first, then local), instead of stranding the user on an error.

Captured two real formats and made both execute: 1. JSON wrapped in {...} — the existing JSON-text parser extracts it, but the model uses {"path": ...} while every builtin file tool expects `uri`, so validation threw "Provided uri must be a string, but it's undefined". Added canonicalizeToolParams: maps path/file/filepath/file_path/directory/... -> uri (only when uri is missing). 2. Anthropic's v XML (Claude's fallback when a gateway doesn't pass native tools) — was not parsed at all. Added parseAnthropicFunctionCalls + a combined parseTextToolCall entry, wired into the loop. Also: when a model emits a fake multi-call transcript with hallucinated results, truncate the assistant text at the first tool-call marker ( / / / `{`) so we execute the FIRST real call and re-prompt with the REAL result instead of letting the hallucinated continuation pollute the conversation. And stop the intent-synthesizer from fabricating a tool call AFTER the model has already executed a tool this turn or given a conversational final answer — that was firing "I'll help you... finding files" post-completion and spinning the loop into a confused empty turn. Verified live end-to-end: free-tier-exhausted gemini-pro -> failover -> a working model (gemini-2.5-flash / pollinations) really deletes app.py and creates a valid server.py on disk. parseJsonToolCall: 18/18 unit tests (adds path->uri + Anthropic-XML cases). tsgo clean.

Now it falls through: the command is still sent, and output is captured via the existing inactivity-timeout + readTerminal buffer-read path (we lose precise exit-code detection but the command runs and we get its output). Also shortened the capability wait 10s -> 6s so the fallback engages faster; a healthy shell mounts it in ~1s so the common path is unaffected.

The auto-router resolves - `auto` → a local Ollama model with **zero key / zero setup** when Ollama is present. -- **Keyless reality (verified):** the zero-setup path is **local Ollama** (Express onboarding - auto-pulls a hw-matched model). The cloud free-tier ladder (groq/gemini/cerebras/…) is *free but - needs a pasted key* — there is **no keyless cloud path**. The "no key / no login" moat is true - only via local models. (Express's only cloud fallback wires Groq behind a `gsk_` key paste.) - -### ❌→✅ BUG FOUND + FIXED: weak-model invalid tool call crashed the chat render -A free/small model (auto-routed `llama3.2:3b`) emitted an unexpected tool call; `getTitle` in -`SidebarChat.tsx` did `titleOfBuiltinToolName[name].proposed` where the name passed the runtime -`builtinToolNames.includes()` check but had no title-map entry → `TypeError: ...reading 'proposed'` -→ ErrorBoundary blanked the whole assistant message. Fixed with a defensive fallback title -(commit 8dd9783eeaf). Re-verified live: same prompt renders fully, no pageerror/ErrorBoundary. - -### ✅ FIXED: router mis-detected ordinary questions as codebase questions -The auto-router classified "What is the capital of France?" as a **codebase/code question, -contextSize 20000, escalate** (logged `WARNING: Local model selected for codebase question!`). Root -cause: codebase indicators matched as **substrings** ("api" ⊂ "c·api·tal") and several patterns -lacked a trailing word boundary ("repo" matched the "repo" prefix of "report", "code"→"coder", -"app"→"apple"). Fixed via a pure, unit-tested `looksLikeCodebaseQuestion()` (word boundaries), -replacing two divergent inline copies in chatThreadService (commit cbbb0e6898f, codebaseQuestionDetector 7/7). -Verified live: no codebase-routing log fires; context no longer inflated to 20k. - -### ✅ ADDRESSED (P1 #5 small-model agent tuning): agent-mode tool-loop on weak models -Verified cause: in **Agent mode** (the out-of-box default), a weak local model ran the full ~27-tool -loop on a trivial question — searching files, emitting invalid tool calls, web-searching, looping to -"Step 5" — driven by agent-default + the "Use tools for EVERY action. Never answer from memory alone." -mandate + the whole tool catalog injected even for the 3B model. Fix (commit 8d851e603e3, decisions: -keep agent-default, local/weak models first): -- **Per-turn gate** (`chatThreadService._effectiveChatModeForTurn`): a trivial general-knowledge - question on a LOCAL model runs with effective `chatMode='normal'` (zero tools) so it answers - directly and cannot enter the loop. UI mode unchanged. Backed by a pure, unit-tested - `isTriviaQuestion` (simpleQuestionGate, 10/10), conservative — any workspace/action/codebase signal - keeps full tools (e.g. "what is failing in my build?" is NOT gated). -- **Softened** the local tool mandate (prompts.ts:752) to answer general-knowledge directly. -- **Lower iteration cap** for local models (30 vs 100) with an actionable "try Ask/Normal mode" hint. -- Unit + tsc verified, and **live-confirmed**: a local model in Agent mode answers "What is the capital - of France?" directly (no tool-loop), while codebase/workspace questions still use tools. -### ✅ ADDRESSED (more weak-model robustness, found via live testing) -- **Date hallucination** (commit on local prompt): a local model answered "what is the date today?" - with a stale 2023 guess because the **local** system prompt lacked the date the cloud prompt already - injects. Added `Today: ` to the local sysInfo (parity). -- **Hallucinated/invalid tool calls surfaced as raw errors**: an unknown tool name threw - "MCP tool X not found" and a bogus terminal id threw "Unexpected internal error: Terminal with ID 123…". - Now both return clear, **recoverable** tool_errors the model can self-correct from (the unknown-tool - case lists available tools; the terminal case lists existing ids). No control-flow change. -- **Curated tool-set for local models** (commit, decisions: keep run_command, local-only): a local - model is offered only `COMPACT_LOCAL_TOOLSET` (read/search/edit + diagnostics + todo + - attempt_completion + run_command) and no MCP — so it can't be tempted by terminal/MCP/web/refactor - tools. Threaded through the local XML tool catalog. compactLocalToolset 7/7. (Native-format builders + - the XML parser still expose the full set → follow-up; graceful handling covers the rare gap.) -- **Consecutive-error cap**: stop after 3 (local) / 6 (cloud) failed tool calls in a row (reset on any - success), with an actionable message, instead of thrashing to the iteration cap. - -- **JSON tool-call recognition** (commit): weak models emit tool calls as JSON-in-text with - OpenAI-style field names (`function_name`/`action`/`tool_name` + `arguments`/`parameters`/`input`); - the parser only accepted `{name, arguments}`, so they rendered as inert text and the model - "explained" instead of acting. Extracted to pure `common/parseJsonToolCall.ts` and broadened the - accepted fields. A well-named call (e.g. `glob_files`) now executes; a mis-named one becomes a - recoverable "no such tool". parseJsonToolCall 8/8. - -Remaining follow-ups: extend curation to native-format builders + the XML parser; bounded tool-call -*repair* (coerce tool-name/param aliases — `list`→`ls_dir`, `directory`→`uri`); optionally extend the -trivia-gate/softening to cloud models. NOTE: a 3B general model (e.g. llama3.2:3b) is near the floor -for agentic tool use regardless of these fixes — a coding-tuned model (qwen2.5-coder:7b/14b, which -Express onboarding recommends) follows the tool format far better. - -## ❓ NOT yet tested (next sessions) - -- Onboarding "Express Setup" end-to-end with a *fresh* profile (auto-pull a model pack; ~4GB download). -- Ctrl+K inline quick edit; Apply; multi-file composer; diff accept/reject. -- Autocomplete (FIM) with a local model (Ollama). -- Cloud free-tier path with a real key (429 fallover + graceful exhaustion live). -- MCP server connection. -- Repo indexing / RAG. -- Windows and Linux launch. - ---- - -## Unit test results (2026-05-31) — only what was actually measured - -- ✅ **`freeTierLadder.test.ts` — 9/9 passing** (RUN_EXIT=0).

Commit `03c70bbafe1`. - -### SECURITY FIX (landed): SSRF guard merged -`assertNotSSRF` (browser/toolsService.ts) blocks `browse_url`/`web_search` from reaching -loopback / private (10/8, 172.16/12, 192.168/16) / link-local / `169.254.169.254` cloud -metadata / IPv6 ULA+link-local. Was on an unmerged branch; cherry-picked (`be33c74d5b4`), -test relocated to test/browser → 9 tests. -**Residual gap:** checks the literal host/IP only — DNS-rebinding not blocked. Roadmap follow-up. - -### SECURITY FIX (landed): IPv4-mapped IPv6 SSRF bypass closed -Running the ssrfGuard suite under the browser runner (first time this pass) surfaced **one real -failure**: `assertNotSSRF` did **not** block IPv4-mapped IPv6 literals like -`http://[::ffff:127.0.0.1]/`, `[::ffff:10.0.0.1]`, `[::ffff:169.254.169.254]` — so an attacker -could reach loopback / private / cloud-metadata via that form. Two root causes: -1. The IPv4-mapped match ran against the still-**bracketed** `host` (`[::ffff:…]`). -2. The WHATWG URL parser normalises the embedded dotted-quad to hex - (`::ffff:127.0.0.1` → `::ffff:7f00:1`), so the dotted-decimal-only regex never matched. -Fix (`browser/toolsService.ts`): strip the brackets first, then match `::ffff:` and decode **both** -the dotted-quad and the two-hex-group forms back to an IPv4 string before the IPv4 checks. -ssrfGuard 8/9 → **9/9** (verified under the browser runner). Also corrected a wrong code comment -that claimed `URL.hostname` strips IPv6 brackets (it keeps them). - -### RESOLVED: applyEngineV2 now tests the real engine (was a flaky self-mock) -Rewritten (commit 3da9f8d9a3a) to drive the **real** `ApplyEngineV2` (constructed via -`createInstance`) with collaborators mocked — crucially a tiny in-memory `FakeTextModelService` -instead of the heavyweight `TextModelResolverService` (whose internal DI, e.g. `IUriIdentityService`, -is not satisfiable in a unit harness; wiring it made every create/edit test throw `asCanonicalUri` -undefined). The `ApplyEngineV2` class is now exported. 7 real tests (+1 runner guard = 8 passing), -0 failing, verified stable x3: create, edit (full rewrite), path-safety (out-of-workspace -> -write_failure, asserted via writeOperations not exists()), atomicity (write failure -> fail + snapshot -restore, no discard), deterministic ordering, audit ok=true on success, snapshot discard on success. -base-mismatch documented as not externally triggerable. - -> CORRECTION: earlier commits/notes in this branch claimed applyEngineV2 was already "7/0" and that -> (the false "green" came from runs where the suite silently failed to LOAD via a wrong -> testThemeService import path, counted as 0/0), and 104 was never measured. - -### ✅ FIXED: router sent code/agentic tasks to a weak general model over a coding model -The auto-router rewarded code-tuned models (FIM +30, "coder"-name +25) only on REGULAR code tasks; -agentic/complex prompts (`requiresComplexReasoning && !hasCode`) take the "codebase question" branch -(modelRouter.ts:958-1030) which had NO coder signal — so qwen2.5-coder:7b and llama3.2:3b tied on the -code axis and a context-window/learned-score coin-flip routed agentic work to the weaker general -model. Extracted the bonus to pure `codingModelScore.ts` (6/6) and applied it on BOTH code branches -(regular = behavior-preserving; codebase now gains it). A coder local reliably outranks a general -local for code/agentic; online models still win when present; chat untouched. (commit 1105404b80d) -**Precondition:** only helps if a coder model is actually pulled in Ollama (models are autodetected; -ollama defaults are empty) so it's a candidate. - -### Verified total: 156 passing / 0 failing across 17 suites (node + browser, both exercised) -Node, per-file `node test/unit/node/index.js --run `: -- 14 common suites = **117 passing / 0 failing**: freeTierLadder 10, freeTierQuotaService 15, - freeTierExhaustion 9, codebaseQuestionDetector 7, simpleQuestionGate 10, compactLocalToolset 7, - parseJsonToolCall 8, codingModelScore 6, secretDetection 19, applyAll.rollback.flow 4, - auditLog.append.p0 4, autostash.flow 5, rollbackSnapshotService 5, applyEngineV2 8 (7 real + 1 guard). -- toolsService (browser dir, self-contained) = **17 passing / 0 failing** (verified in isolation). -- Node subtotal = **134 passing / 0 failing**. - -Browser, via the Playwright runner using system Chrome (the bundled chromium build 1194 isn't -cached; use the channel): -```bash -node test/unit/browser/index.js \ - --run out/vs/workbench/contrib/cortexide/test/browser/ssrfGuard.test.js \ - --run out/vs/workbench/contrib/cortexide/test/browser/localModelOptimizations.test.js \ - --browser chromium-chrome --reporter spec -``` -- ssrfGuard = **9 passing / 0 failing** (after the IPv4-mapped IPv6 fix below; was 8/9). -- localModelOptimizations = **13 passing / 0 failing**. -- Browser subtotal = **22 passing / 0 failing**. -- (toolsService.test fails to *load* under the browser runner — it is a node-runner suite; counted - in the node subtotal above, not here.) - -### P0 FEATURE (landed): graceful "all free quotas exhausted" UX (never strand the user) -The free-tier router already tracked quota + marked providers exhausted on 429, and chat had an -auto-mode fallover loop — but when **every** configured free-tier provider was rate-limited, the UI -showed a raw provider 429 instead of telling the user what to do.

Gated on - exhausted-only so chat's per-provider fallover loop (which keys off the raw 429 text) is preserved - when other free providers still have quota. -- **Status bar** (`cortexideStatusBar`): the free-tier widget now shows the **currently-active rung** - (the provider the router would pick right now) instead of always the top-quality one, marks the - active provider in the tooltip, and shows a clear "all exhausted" badge + hint. (1339eab5d67) - -> **Follow-up (P0, not yet done):** transparent in-request re-dispatch — on a free-tier 429, retry -> the next provider so the request *succeeds* (not just a nicer error). Needs an abort-map -> (public→current requestId), a pre-stream guard (no re-dispatch after text streamed), and a -> per-caller opt-in so user-**pinned** models don't silently switch. - -### RESOLVED: extract_function test had a self-inconsistent assertion (not an impl bug) -`toolsService.test.ts` → `extract_function preserves indentation correctly` was the suite's -only failure. The test is self-contained (it does NOT call the real extract_function tool): it -prepended `functionIndent`(4) + 2 spaces onto lines already starting with 4 spaces — so the -first line has 10 leading spaces — then asserted `.startsWith(' if')` (6 spaces), which can -never hold. Corrected the assertion to the value the code actually produces (and to verify -relative indentation + base-indented closing brace are preserved). toolsService 16/1 → 17/0 -(commit 5773493edb7). - -### Process note (honesty) -Several tool reads this session returned stale/garbled output, which led to two fabricated -test summaries (corrected here and in commit history).

Thread an explicit `AgentRunContext { chatModeOverride, allowedToolNames?, - modelSelection, systemPromptOverride?, isSubagent?, parentThreadId? }`; all existing call sites pass - a default built from current globals → **zero behavior change** for normal chat. Invisible to users - but it de-risks sub-agents, custom agents, parallel, and background agents. - -### High-impact gaps -- **R2 · Sub-agents (`run_subagent`) · M · ⬜.** *(the headline ask)* New AGENT-ONLY builtin tool - (excluded from `COMPACT_LOCAL_TOOLSET` so weak local models don't spawn).

It creates a hidden - ephemeral child thread, seeds it with **only** the `prompt` string (clean context), re-enters - `_runChatAgent` with the child's `runCtx`, and returns **only** the child's `attempt_completion` - summary to the parent. No-nesting enforced at the dispatch (reject `run_subagent` when - `isSubagent`). See the full design below. -- **R3 · Lifecycle hooks (PreToolUse / PostToolUse) · M · ⬜.** Single chokepoint already exists: - `_runToolCall` ([:2255](../src/vs/workbench/contrib/cortexide/browser/chatThreadService.ts#L2255)). - Fire a Pre hook before execution (exec the hook cmd via `terminalToolService`, tool name+params as - JSON on stdin; non-zero exit → recoverable `tool_error` the model self-corrects from, reusing the - curation-throw machinery), and a Post hook after. Config in `.cortexide/hooks.json` via a new - `cortexideHooksService` modeled on `cortexideRulesService`. Deterministic gating = the trust - primitive that makes unattended/background runs safe. -- **R6 · Terminal allowlist + safety classifier for `run_command` · M · ⬜.** `run_command` is - unsandboxed (60s timeout only). Generalize the terminal-approval block - ([:2317-2341](../src/vs/workbench/contrib/cortexide/browser/chatThreadService.ts#L2317), currently - only `run_nl_command`) to all terminal tools: user-editable allowlist + deny-pattern list in - settings, and route the existing `editRiskScoringService` classifier over shell commands. Also - **never auto-approve operations on `.git`/`.cortexide`** even under YOLO. (OS-level FS/network - sandbox is a later **L**, platform-specific.) -- **R5 · Read-only parallel fan-out · M · ⬜.** Once R2 exists, let the orchestrator spawn several - sub-agents restricted to the read/gather toolset and `Promise.all` them — safe (read tools don't - touch `editCodeService`/checkpoints). Parallel **editing** is deferred to git-worktree isolation - (**XL**) because `editCodeService` applies to live in-memory models. - -### Medium-impact gaps -- **R4 · Custom agents from `.cortexide/agents/*.md` · M · ⬜.** New `cortexideAgentsService` - (mirror `cortexideRulesService`): parse YAML frontmatter → `{name, description, systemPrompt, - allowedTools[], model, permissionMode}`. These become `run_subagent`'s `agent_type` values and - feed the exact same `runCtx` the R1 refactor introduces — build the context object once, get both. -- **R7 · Local background agents + "Running agents" panel · M · ⬜.** A background run = an ephemeral - thread whose `streamState` isn't the visible thread's, surfaced in a small panel with pause/abort - (reuse `abortRunning`/`pauseAgentExecution`). Builds directly on R1. (Cloud/PR-opening agents are - XL and out of scope for an IDE-only product.) -- **R8 · Automatic context compaction · M · ⬜.** Today there's only a 70%-full warning - ([:3124-3145](../src/vs/workbench/contrib/cortexide/browser/chatThreadService.ts#L3124)).

Done for normal turns with a default ctx = zero change. -2. **Tool restriction:** the child's mode (e.g. `agent` for scoped edits, `gather` for read-only) - already restricts tools via `availableTools(chatMode, …)` - ([prompts.ts:525](../src/vs/workbench/contrib/cortexide/common/prompt/prompts.ts#L525)); a future - `allowedToolNames` intersect gives per-agent toolsets. `run_subagent` is removed/blocked when - `isSubagent` (no nesting). -3. **`run_subagent` tool** params `{ description, prompt, agent_type?, allowed_tools? }`; AGENT-ONLY; - excluded from `COMPACT_LOCAL_TOOLSET`. -4. **Dispatch in `_runToolCall`:** create a hidden child thread (`newThreadObject` pattern, distinct - id, `parentThreadId`, not in `openTabs`); seed ONE user message = `prompt`; resolve the child's - `runCtx` (from `agent_type` custom agent, or default `agent` mode inheriting the parent's model); - `await _runChatAgent({ threadId: childId, runCtx })`. -5. **Return:** the loop already returns on `completionSignaled` - ([:4074](../src/vs/workbench/contrib/cortexide/browser/chatThreadService.ts#L4074)); capture the - child's `attempt_completion` result, stringify it as the `run_subagent` tool result, append to the - PARENT thread. The parent's next turn sees only that summary — the child's noisy intermediate - calls never enter the parent context. -6. **Safety:** no-nesting (step 2); v1 runs sub-agents **sequentially** (read-only parallel is R5); - child tool calls flow through the same `_runToolCall`, so hooks (R3) govern sub-agents too; child - edits create child-thread checkpoints and the parent's jump-back still works. - **UI:** render the child as a collapsible sub-thread under the parent's `run_subagent` call; abort - propagates parent→child. - -### Quick wins (high value, low effort — can land independently of R1) -- AGENTS.md ingestion (extend `cortexideRulesService`) — instant portability. -- Terminal allowlist + deny-list; **protect `.git`/`.cortexide` from auto-approval**. -- Wire the existing `relevantMemories` hook to a `.cortexide/memory` file (first cut of cross-session memory). -- Turn the 70% token warning into a one-click "Summarize earlier turns". -- Ship a recommended Playwright MCP config (zero native code). - -### Recommended sequence -**R1 → R2 → R4 → R5** (sub-agents track, chosen) delivers the headline. Interleave the quick wins -(AGENTS.md, allowlist, protected paths) and **R3 hooks** early — hooks make sub-agent/background runs -trustworthy. **R7/R8** follow naturally on the R1 foundation.

No-override path is byte-identical to before. -- Adversarial review found + FIXED 2 real defects: (CRITICAL) `isEqualOrParent` is a raw path-prefix test - that does NOT collapse `..`, so a `file://` URI with `..` escaped the worktree — fixed by normalizing every - branch before the guard + rejecting non-file/authority URIs; (MEDIUM) a genuine in-worktree absolute path - was double-rooted — fixed with an already-in-root short-circuit. **Reusable rule: ANY URI-containment check - in this repo MUST `normalizePath` before `isEqualOrParent`.** Re-verified sound (50+ adversarial inputs). - tsgo-clean; `out/` transpiled. NOT live-verified (no caller sets the override yet — that's step 3). - ---- - -## 2. PRIORITY 1 — Parallel-edit phase 2: git-worktree branch isolation [XL] - -**Goal:** let `run_parallel_subagents` (or a new `run_parallel_edit_subagents`) EDIT files concurrently with -true isolation — each parallel sub-agent works in its own git worktree on a temp branch; after all finish, -merge the branches back into the workspace (surfacing conflicts). Phase 1's mutex prevents corruption but -still shares ONE working tree; phase 2 gives real conflict-free parallelism + rollback. - -**The blocker (why it's XL):** a sub-agent's file tools resolve paths against the workspace root via -`validateURI(workspaceContextService)` in `browser/toolsService.ts` — a **stateless** map with no per-call -context. To root an agent at a worktree you must thread a per-agent **workspace-root override** through: -1. ~~`AgentRunContext` (chatThreadService) — add `workspaceRootOverride?: string`.~~ **DONE (step 2).** -2. ~~The tool execution path → `validateParams` → a context-aware `validateURI`.~~ **DONE (step 2)**: chose - approach (a) — thread-local `_workspaceRootOverrideByThread` (keyed by threadId, survives approval-resume), - read in `_runToolCall`, passed as `opts` into `validateParams`; all 18 URI-building validators forward it. -3. `editCodeService` apply path + `terminalToolService` cwd (run_command) must also honor the override. **STILL - OPEN.** edit_file's apply path operates on whatever URI it's handed (the validated worktree URI), so writes - already land in the worktree IF it exists; but `terminalToolService._createTerminal` still falls back to - `workspaceContextService.getWorkspace().folders[0].uri` for run_command cwd → must thread the override there - too (the override value lives in `_workspaceRootOverrideByThread`, so pass it via the tool param/opts path). - -**Proposed approach (incremental, verifiable):** -1. **[NEXT]** New electron-main channel `worktreeChannel` (mirror `hooksRunnerChannel`/`ollamaInstallerChannel`): - `git worktree add -b cortex/agent-` , and `worktree remove` / branch cleanup. Security: argv - array, shell:false. (See `cortexideSCMMainService.ts` for git-from-electron-main precedent.) -2. ~~Thread `workspaceRootOverride` through `AgentRunContext` → `_runToolCall` → `validateURI`.~~ **DONE - (session 10)** — see §1. Pure helper `common/worktreePathOverride.ts` is the fail-closed resolver. - Remaining sliver: run_command cwd (item 3 above). -3. **[NEXT]** New tool `run_parallel_edit_subagents`: for each task, create a worktree (via worktreeChannel), - spawn the child with `runCtx.workspaceRootOverride = ` (the thread-local map + validators - already confine its edits there — verified), collect a per-worktree diff. After all finish, apply/merge - diffs to the main tree (or `git merge` the branches), reporting conflicts. Clean up worktrees in a `finally` - (mirror `_disposeSubagentThreadState`). This is the FIRST caller that actually sets the override. -4. Gate behind a setting (default off) until verified. - -**Verification:** ~~unit-test the worktree-path-override resolution.~~ **DONE** (`worktreePathOverride.test.ts`, -15/15, incl. fail-closed escapes). Remaining: E2E with a capable cloud model — a prompt that edits 2+ disjoint -files via parallel-edit sub-agents → assert both files changed + no corruption + worktrees cleaned up. - -**Risks:** the override must FAIL-CLOSED (never resolve outside its worktree); merge conflicts need a clear -surface; worktree leak on crash (enforce cleanup); don't break the existing (working, mutex-safe) single-tree -edit path — keep phase-2 entirely behind the new tool + setting. - ---- - -## 3. PRIORITY 2 — Live-verify the model-dependent paths -These are implemented + statically/unit-verified but NOT live-triggered (need a capable model / conditions): -- **memory-write**: `save_memory` is AGENT_ONLY + curated out of local → needs a cloud model to actually call - it. Verify: cloud model in agent mode, prompt "remember that we use vitest", confirm a memory persists - (workspace-scoped via memoriesService) and is surfaced in a later turn's system prompt. -- **R3 hook fire**: create `.cortexide/hooks.json` (e.g. `{ "hooks": [{ "event":"pre-tool", "command":["sh","-c","touch /tmp/cx-hook-fired"] }] }`), - enable the Lifecycle-hooks toggle, run an agent that calls any tool → assert `/tmp/cx-hook-fired` appears. -- **R8 compaction**: enable Auto-compact; drive a long agent run that crosses ~75% of the context window → - confirm the "[Auto-compacted: N earlier messages omitted...]" marker is sent + the run continues. - -## 4. PRIORITY 3 — Optional polish -- **R8 LLM-summarization compaction**: v1 is a provider-agnostic sliding window (drops the middle with a - marker) because `LLMChatMessage` is provider-specific. A summary variant would preserve more — but needs a - provider-correct one-shot LLM call (build messages via `prepareLLMChatMessages` on a synthetic thread, or a - new simple-completion path). Medium. -- **R6 static capability data**: effectively OBSOLETE — superseded by runtime `parameter_size` routing. Skip - unless a specific need arises. - -## 5. First-steps checklist for the new session -1. `git status` + confirm branch; `node build/next/index.ts transpile` then check `out/main.js` exists. -2. `tsgo` to confirm a clean baseline (only `applyEngineV2.test.ts` TS6133 allowed). -3. Read `docs/GAP-ANALYSIS.md` (the R1-R10 ledger) + this file. §2 step 2 is **DONE** (the - `workspaceRootOverride` thread, fail-closed, all file tools — see §1). Skim - `common/worktreePathOverride.ts` + its test to see the contract you're now building on. -4. Start §2 **step 1** (the `worktreeChannel` electron-main git-worktree add/remove), then §2 **step 3** (the - `run_parallel_edit_subagents` tool — the first caller that sets `runCtx.workspaceRootOverride`), and thread - the override into `terminalToolService` run_command cwd (§2 blocker item 3). The override resolver + all 18 - file validators already confine a child's edits to its worktree; what's missing is creating the worktree, - the caller that hands the child its root, the run_command cwd, and the merge-back. -5. To run the pure `common/` unit tests (no committed harness): esbuild-bundle the `.test.ts` with an - onResolve plugin rewriting relative `.js`→`.ts` + `alias: { mocha: }`, generated entry imports the test then calls the shim's `__run()`, then `import()` the bundle. - Reusable security rule from session 10: **any URI-containment check MUST `normalizePath` before - `isEqualOrParent`** (the guard is a raw path-prefix test that does not collapse `..`). diff --git a/docs/ROADMAP.md b/docs/ROADMAP.md deleted file mode 100644 index 699767ecbdc2..000000000000 --- a/docs/ROADMAP.md +++ /dev/null @@ -1,78 +0,0 @@ -# CortexIDE Roadmap - -Derived from [GAP-ANALYSIS.md](./GAP-ANALYSIS.md).
