feat(i18n): extract core_commands.py user-facing strings

[thomwebb]

What

Migrates 41 user-facing emit_* strings across 7 slash-command handlers in command_line/core_commands.py to the t() catalog — the #2 extraction target at 47 raw audit sites (41 genuinely translatable; 6 false positives).

Result

47 raw → 6 — all remaining hits are false positives:

• Rich-markup f-strings in picker-failure fallback paths (Text.from_markup(f"[dim]...{var}...[/dim]"))
• Traceback diagnostics (f"Traceback: {traceback.format_exc()}")
• Pure-variable agent description strings (f"{new_agent.description}")

31 new cmd.* keys added to en-US.json; 5 reuse existing keys:

Existing key reused	From
cli.goodbye	/exit goodbye message
cfg.agent.not_found	agent not-found error
cli.agent.available	agent listing
cmd.agent.picker_failed	model picker failure (same message)

Key groupings

Namespace	Commands covered
cmd.cd.*	/cd: success, list-error, agent-updated, reload-error, not-a-dir
cmd.paste.*	/paste: no-image, hint, count, send-hint, failed
cmd.tutorial.*	/tutorial: chatgpt-oauth, claude-oauth, complete, skipped
cmd.agent.*	/agent: already-using, switch-failed, switched, cancelled, picker-failed, usage
cmd.model.*	/model: success, cancelled, usage, available
cmd.add_model.*	/add_model: success, failed
cmd.model_settings.*	/model_settings: success, agent-reloaded, reload-failed, failed
cmd.plan.usage	/plan: usage error

Bonus fix

Renamed the loop variable t → token in handle_generate_pr_description_command — it was shadowing the module-level t() import (caught by ruff F402).

Tests

tests/i18n/test_core_commands_i18n.py (10 tests): namespace populated, all keys resolve + pseudolocalize, interpolation for each command group, no leftover placeholders, module imports cleanly. All 128 existing i18n tests still pass. ruff clean.

Independence

Touches only core_commands.py, en-US.json, and the new test — no overlap with any open PR.

[thomwebb]

Adversarial Review — Automated (code-puppy-4aeaa3)

Verdict: CONDITIONAL PASS — mechanical extraction is correct, no crash vectors. Three issues before merge.

---

Must Fix

1. Key reuse: cmd.agent.picker_failed used inside handle_model_command

core_commands.py:488 (approx) — the model command's picker-failure path reuses cmd.agent.picker_failed. If a translator ever needs to word these differently (agent picker vs model picker), there's no seam. Create cmd.model.picker_failed in en-US.json and use it in handle_model_command.

2. Test namespace floor too loose

tests/i18n/test_core_commands_i18n.py — assert len(_cmd_keys()) >= 25 allows 6 keys to silently vanish. The PR adds 31 keys; floor should be >= 31.

3. No targeted interpolation test for cmd.add_model.failed

The key has an {error} placeholder. test_no_leftover_placeholder_for_supplied_params catches this generically with "X", but a param-name typo in the catalog would still pass. Add one explicit assert.

---

Track / Follow-up (not merge blockers)

• Text.from_markup("[yellow]Usage:[/yellow] /agent <agent-name>") near line 384 is content-identical to cmd.agent.usage but bypasses t() — will drift if a translator updates the catalog key
• "No description" fallback (line 371) is user-visible, still raw
• "Failed" in result dispatch in the undo handler will silently break if undo_manager.py ever gets localized — track in a ticket
• Add # i18n: skip - developer output comments on the two Traceback: f-string lines so future auditors don't re-flag them

---

Everything else checks out: import is at module level, all 31 keys exist in en-US.json, all param names match, t() is crash-safe (missing key returns key, missing param leaves placeholder intact), no Rich markup in catalog values.

Review feedback addressed — commit 3b67f7ed

Automated fix pass (code-puppy-4aeaa3). Applied the three "must fix" items:

Landed:

• Added new key cmd.model.picker_failed ("Model picker failed to open: {error}"); handle_model_command no longer reuses cmd.agent.picker_failed
• Test floor tightened: >= 25 → >= 32 (matches actual current key count)
• Added test_add_model_failed_interpolates_error_param — explicit interpolation check that catches param-name typos independently of the generic sweep test
• Also added the new cmd.model.picker_failed key to test_model_keys_interpolate

Verification:

• pytest tests/i18n/test_core_commands_i18n.py -q → 11 passed
• ruff check --fix / ruff format → clean
• Catalog JSON parses; 32 cmd.* keys

Deferred (track as follow-up, not blocking):

• Text.from_markup("[yellow]Usage:[/yellow] /agent <agent-name>") at ~line 384 duplicates cmd.agent.usage content but bypasses t()
• "No description" fallback at line 371 still raw
• "Failed" in result dispatch in undo handler will break if undo_manager.py gets localized
• Traceback: f-string lines still need # i18n: skip - developer output comments

CI should re-run on the new commit.

Rebased + piggyback test fix

Rebased onto latest main (now at f0dab866) and added a small piggyback commit fixing an unrelated broken test that CI was tripping over.

Context

Upstream commit f0dab866 (feat: add GPT-5.6 reasoning context and mode) added reasoning_context and reasoning_mode to supported_settings for gpt-5.6* models in chatgpt_oauth/utils.py but did not update tests/plugins/test_chatgpt_oauth_utils.py::test_add_models_to_extra_config_gpt54_and_newer_support_xhigh, which asserts a hardcoded 3-item list. Result: main's own Build and Publish to PyPI run is failing for the same reason.

What the piggyback commit does

Splits the assertion so codex-gpt-5.6-* variants expect the extra fields:

expected_settings = ["reasoning_effort", "summary", "verbosity"]
if model_name.startswith("codex-gpt-5.6"):
    expected_settings.extend(["reasoning_context", "reasoning_mode"])
assert model_config["supported_settings"] == expected_settings

Verified locally: test passes on this branch.

Cleanup

This commit is a piggyback and will drop from the branch automatically once the same fix lands on upstream main via a rebase.

[mpfaffenberger]

Reviewed from a local worktree — extraction is clean, the t loop-var shadowing fix is a nice catch, and reusing cfg.agent.not_found / cli.agent.available instead of minting duplicate keys is good DRY. tests/i18n/ (129 tests) and ruff check both pass locally. A few things before merge:

** Drop the test(chatgpt): update supported_settings expectation for gpt-5.6 commit (applies to all 5 of these PRs)**

Main already has an equivalent fix, but with a subtly different guard:

• main: if model_name.startswith("codex-gpt-5.6-"): (trailing dash)
• this PR: if model_name.startswith("codex-gpt-5.6"):

Same lines, different content → guaranteed merge conflict, and it's unrelated to i18n anyway. A rebase onto current main should make this commit vanish entirely. Same note applies to #653/#654/#655/#656 which all carry the identical commit.

** String reworded during extraction**

cmd.model.picker_failed = "Model picker failed to open: {error}" but the original literal was "Interactive picker failed: {e}" — and its sibling cmd.agent.picker_failed does preserve the original wording. Extraction PRs are much easier to review when strings move verbatim; if the rewording is intentional, worth a line in the PR description.

** Nits**

• emit_warning(f"Traceback: {traceback.format_exc()}") — the Traceback: label is still a raw literal (2 sites). Fine to punt to a follow-up, just noting it'll show up in the audit.
• cmd.paste.count ("Total pending clipboard images: {count}") — label-style counts are fine, but flagging as a future ngettext candidate per docs/I18N.md.

The test_add_model_failed_interpolates_error_param guard against placeholder-name drift is a genuinely nice touch.

[thomwebb]

Review feedback addressed — commit 18716cf6

Automated fix pass. Applied the one wording fix Mike flagged:

cmd.model.picker_failed restored to the original literal:

- "Model picker failed to open: {error}"
+ "Interactive picker failed: {error}"

Parameter name {error} kept (matches sibling cmd.agent.picker_failed and per your DRY suggestion). No test change needed — the only test on this key asserts substring "boom" on the interpolated value, so it's wording-agnostic.

Test result: 129 passed (tests/i18n/).

Deferred (per your call as nits)

• Traceback: raw label at 2 sites — follow-up
• cmd.paste.count ngettext candidate — follow-up

Heads-up: quality job failure is a repo-wide ruff-version drift, not this PR

The quality CI job is red on all currently-open PRs (including this one) with ~5900 lint errors. Verified locally that the same errors are reported against untouched main:

$ uv tool run ruff check .   # ruff 0.16.0, the version CI now installs
Found 5902 errors.

Root cause

.github/workflows/ci.yml does an unpinned install:

- name: Install dev dependencies (ruff)
  run: pip install ruff        # ← no version pin

pyproject.toml only sets a floor (ruff>=0.11.11). Ruff 0.16.0 (released recently) enabled new default rules (SIM117, EXE001, BLE001, etc.) that main has never been linted against. Every open PR now fails quality on inherited-code lint errors from files it doesn't touch.

This PR's diffs are clean

Ran the older pinned ruff locally on the branch — All checks passed!.

Suggested one-line fix (whenever you get to it)

Pin ruff in ci.yml to a version that matches what main was last known-clean at:

- run: pip install ruff
+ run: pip install "ruff==0.15.13"

Or add an explicit upper bound in pyproject.toml's dev group so uv tool run ruff and CI agree.

Happy to open a separate cleanup PR for either the pin or a repo-wide ruff check --fix --unsafe-fixes . sweep — just say the word. Not folding it in here to keep the diff scope tight for review.

[mpfaffenberger]

CI follow-up: I retriggered the failed Quality Checks run — it failed again, and it will keep failing on rerun regardless of your changes. Root cause: this branch's merge snapshot predates main's ruff pin (pip install 'ruff>=0.15,<0.16' in ci.yml — added after ruff 0.16.0 changed the default rule set and produced 5,901 "new" errors repo-wide). Reruns reuse the original merge commit, so they keep installing unpinned ruff 0.16.

Fix is the rebase onto current main already requested in the review (which also drops the duplicated gpt-5.6 test commit). A fresh push will generate a new merge ref with the pinned ruff and the lint job should go green — your actual changes pass ruff check locally against main's config.

🌍 i18n translations added (es, fr-CA) — 32 new keys per locale

Adding Spanish (neutral Latin American, target for the es.json parent + all es-* regional variants via fallback) and Canadian French translations for the 32 new English keys this PR introduces.

What's here

• code_puppy/i18n/locales/es.json: +32 keys — inclusive register (¡Bienvenido(a)), reflexive constructions, neutral LatAm terminology, formal-friendly tone matching the existing 15 keys
• code_puppy/i18n/locales/fr-CA.json: +32 keys — Canadian French, Bienvenue dans style, French typography (space before : ; ! ?), Canadian variants (fichier, répertoire, courriel where applicable)

Placeholder integrity, emoji preservation, Rich markup, and \n counts verified programmatically per key — 100% mechanical parity with the English source.

Encoding

New entries written as raw UTF-8 (ensure_ascii=False) rather than \uXXXX escapes so translation reviewers can read/edit ¡, ó, é, à, 🐶, ✅ directly. This aligns with the convention es.json has shipped with since day one; fr-CA.json existing keys were normalized to raw UTF-8 as a side effect of the merge (loader supports both; JSON spec allows both).

Adversarial review

An adversarial reviewer (parallel subagent, "assume defects, find them") ran over all 4 PRs' translations. This PR's specific findings and fixes are captured in the follow-up commit(s).
