echo "1+1" | ccp -p # → 2CC Pure is based on decompiled CCB v2.6.11 sources with these key changes:
| Component | Status | Notes |
|---|---|---|
| Sentry error tracking | ❌ Removed | Third-party data upload |
| Anthropic telemetry | ❌ Blocked | CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 |
| Langfuse monitoring | 🟡 Dormant | Code preserved (src/services/langfuse/), activates with keys |
| GrowthBook remote config | 🟡 Local fallback | 1,256-line client, auto-falls-back to local defaults |
| Category | Feature | Status |
|---|---|---|
| Agent Protocol | ACP (external agent bridge/session/permissions) | ✅ |
| Browser | Chrome Use (GUI automation) | ✅ |
| Computer Use (GUI automation) | ❌ disabled¹ | |
| Remote Control | BRIDGE_MODE (React Web UI + WebSocket/SSE) | ✅ |
| SSH_REMOTE (2,029-line full implementation) | ✅ | |
| Autonomy | PROACTIVE + DAEMON + COORDINATOR_MODE | ✅ |
| BG_SESSIONS (ps/logs/attach/kill) | ✅ | |
| Memory | EXTRACT_MEMORIES + LODESTONE + AWAY_SUMMARY | ✅ |
| Reasoning | ULTRATHINK + ULTRAPLAN + VERIFICATION_AGENT | ✅ |
| Context | CONTEXT_COLLAPSE (3-tier, v2.8.0) + HISTORY_SNIP | ✅ |
| Tools | TOKEN_BUDGET + PROMPT_CACHE_BREAK_DETECTION | ✅ |
| IPC | UDS_INBOX + LAN_PIPES (process pipes) | ✅ enabled |
| Voice | VOICE_MODE | 🟡 Code complete, needs Anthropic OAuth |
| Scheduling | KAIROS / KAIROS_BRIEF | 🟡 Code complete, needs GrowthBook + OAuth backend |
¹ Computer Use requires macOS accessibility APIs (
SCContentFilter,NSWorkspace). Excluded from no-split build (build.ts) — causes "1 MCP server failed" noise on Linux.² UDS_INBOX / LAN_PIPES — Now fully enabled. Cold-start hang resolved:
setup.tsgates startup in pipe mode (!getIsNonInteractiveSession()), andudsMessagingis lazily loaded viaawait import()in print mode. Both interactive and pipe modes verified stable.
Source code (Datadog / GrowthBook / BigQuery / 1P Event Logging) is preserved. All upstream reporting blocked via CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1. A local JSONL sink at logEvent() captures 70+ events to ~/.claude/local_analytics.jsonl.
python3 scripts/analyze_analytics.py # today's event report
tail -f ~/.claude/local_analytics.jsonl # real-time trace→ Claude Code's Light and Shadow: A Telemetry Deep-Dive
Peer module to Personality system. The multi-agent communication layer — faster, simpler, and less error-prone than Anthropic's original event sourcing.
Full design doc:
黑板书通信系统设计文档(Chinese) | Evolution log
SQLite-backed blackboard with structured key naming for compaction-resistant multi-agent coordination. Every state mutation is recorded as both an audit event and a key-value entry in a single transaction — workers write, coordinator reads, janitor cleans.
worker writes → recordEvent() → [events + kv in single SQLite tx]
coordinator reads → latest state by key → janitor reaps stale entries
| Component | File | Purpose |
|---|---|---|
| BlackboardStore | src/blackboard/BlackboardStore.ts |
SQLite CRUD: upsert, prefix query, CAS |
| KvHelpers | src/blackboard/kvHelpers.ts |
Structured key builders (workerKey()) + parsers (parseWorkerKey()) |
| BlackboardJanitor | src/blackboard/BlackboardJanitor.ts |
Rule engine: reaps expired keys, cleans orphans, monitors heartbeats |
| eventRecorder | src/blackboard/eventRecorder.ts |
recordEvent() — single transaction writes both events and kv tables |
| RemoteEventStore | src/coordinator/remoteEventStore.ts |
HTTP client, cross-machine (Phase 2) |
| HTTP Server | src/coordinator/eventHttpServer.ts |
Bun.serve:9742, zero deps |
Key convention: worker:N:status, worker:N:result, team:sources, coordinator:decision
Deprecated: teamEventStore.ts (JSONL event log) and teamProjection.ts (fold logic) — preserved in persist/coordinator-event-sourcing branch for reference.

messagesForQuery
→ ① HISTORY_SNIP [Scalpel] Precise message deletion
→ ② CONTEXT_COLLAPSE [Brain] Intelligent collapse (replaces autoCompact)
→ ③ autocompact [Guillotine] Fallback traditional compression
Flow: Before each API call, the scheduler checks token usage — 90% marks a candidate span, 95% triggers compaction. DeepSeek v4 Flash generates a smart summary (99%+ compression rate, zero hallucination); falls back to truncation if the model is unavailable; sliding-window tail cut as last resort.
State machine: staged → spawn → commit (enqueue candidate → call model for summary + risk score → replace original messages).

| CONTEXT_COLLAPSE | 3,001 lines / 151 tests, scheduler + ctx-agent + queryHaiku | ✅ v2.8.0 |
