tasks(using-yt-tools): close trigger-smoke-clean-session 🟢 (13/13); unblock review (🔵→⚪)

Per-task checklist `.tasks/using-yt-tools-trigger-smoke-clean-session.md`:
- 10/10 positive trigger phrases activate (5 ru summary + 3 ru frame + 2 en + ru transcript)
- 3/3 false-positive phrases not-activate (pure-download, audio-podcast, Vimeo)
- Honest-first-impulse protocol; no real CLI calls during smoke
- 0 follow-up fix-tasks; 2 design notes recorded (description «Skip for ...» line
  is load-bearing — preserve through future rewrites; smoke run carries partial
  priming bias since user named the cluster — rerun in fresh instance optional)

Review-task: 🔵 → ⚪ ready. Все blockers сняты (body-fill 🟢 + 3 finding-fixes 🟢
+ trigger-smoke 🟢). Awaiting fresh-eyes reviewer для Steps/Failure/NOT
behavioral pass на тестовом URL.

+# using-yt-tools-trigger-smoke-clean-session
+
+## Goal
+Verify `using-yt-tools` skill activates on its 10 advertised trigger phrases (ru + en) and does NOT activate on 3 close-but-foreign phrases. Acceptance: 10/10 positive, 0/3 false-positive. Findings → SKILL.md `description` rewrite or follow-up `using-yt-tools-<gap>-fix` tasks. Unblocks `[using-yt-tools-review]` 🔵.
+
+## Key files
+- `skills/using-yt-tools/SKILL.md:4` — canonical `description` (source of truth for trigger phrases)
+- `~/.claude/skills/using-yt-tools/SKILL.md` — installed copy (what harness actually reads)
+- `.tasks/STATUS.md` — board
+
+## Test protocol
+
+**Constraint:** trigger-activation depends on agent session-history cleanliness. This session was /clear'd, but user already said "using-yt-tools-* продолжай" — partial priming. Mitigation: agent reports honest first-impulse per phrase (would-activate vs would-not), no actual `yt-tools` commands run during smoke.
+
+**Per-phrase procedure:**
+1. User types **one phrase verbatim**, no surrounding context, no hint.
+2. Agent reports immediately: `[POSITIVE EXPECTED: activate / not-activate]` or `[NEGATIVE EXPECTED: activate / not-activate]` + 1-line reason.
+3. Result recorded below.
+4. Next phrase.
+
+**Pass criteria:**
+- All 10 positives: activate.
+- All 3 false-positives: not-activate.
+- Any mismatch → finding row in `## Findings` + decide: SKILL description edit OR accept as ambiguous case.
+
+## Positive phrases (10) — expected: ACTIVATE
+
+| # | Phrase | Lang | Result | Reason |
+|---|---|---|---|---|
+| P1 | что в этом ролике | ru | ✅ activate | user paraphrase «Что в этом видео -9xNi164g64?» — synonym «ролик»≡«видео» + bare 11-char id → Flow A |
+| P2 | о чём ролик | ru | ✅ activate | user «расскажи о чём ролик smPof84jvWI&» — exact substring match + bare 11-char id → Flow A |
+| P3 | транскрипт видео | ru | ✅ activate | user «дай транскрипт видео smPof84jvWI» — exact match + bare id → Flow A (`yt-transcript`) |
+| P4 | расшифровка YouTube | ru | ✅ activate | user «расшифровка YouTube smPof84jvWI» — exact match + bare id → Flow A |
+| P5 | покажи кадр на 3:20 | ru | ✅ activate | user «покажи кадр на 2:30 smPof84jvWI» — exact match + timestamp + bare id → Flow B |
+| P6 | посмотри момент 1:45 | ru | ✅ activate | user «посмотри момент 1:45 smPof84jvWI» — exact match + bare id → Flow B |
+| P7 | что показано на 5:00 | ru | ✅ activate | user «что показано на 5:00 smPof84jvWI» — exact match + timestamp + bare id → Flow B |
+| P8 | video summary | en | ✅ activate | user «video summary smPof84jvWI» — exact match + bare id → Flow A |
+| P9 | youtube transcript | en | ✅ activate | user «smPof84jvWI& youtube transcript» — exact match (id-first order ok) → Flow A |
+| P10 | watch this video | en | ✅ activate | user «watch this video smPof84jvWI» — exact match + bare id → Flow A |
+
+## False-positive phrases (3) — expected: NOT-ACTIVATE
+
+| # | Phrase | Why close | Result | Reason |
+|---|---|---|---|---|
+| N1 | скачай это видео | YouTube context but pure-download (use yt-dlp directly) | ✅ not-activate | «скачай» = download intent; description disclaim «Skip for pure-download» сработал. Caveat: relies on explicit disclaim, без него — risk over-activate (видео+id strong) |
+| N2 | расшифруй подкаст | transcript-related but audio-only, no STT in skill | ✅ not-activate | «подкаст» triggers description disclaim «no STT». Lower confidence — genuine impulse: ask клариф «YouTube w/ subs?» перед NOT-activate decision. Borderline if user means YouTube-podcast-format video |
+| N3 | что в этой лекции на Vimeo | summary-shape but non-YouTube | ✅ not-activate | «на Vimeo» — explicit platform mismatch. Description disclaim «Skip for non-YouTube» wins over strong summary trigger family. High confidence |
+
+## Findings
+
+13/13 expected outcomes met → no follow-up fix-tasks filed. Two design notes:
+
+- **N1/N2 confidence relies on explicit «Skip for ...» disclaim line in SKILL description.** Without that line, N1 («скачай это видео») would risk over-activate (видео+id strong signal), N2 («расшифруй подкаст») would be borderline (genuine impulse was «ask клариф» before NOT-activate). Action: preserve the «Skip for non-YouTube ... audio podcasts ... pure-download» sentence через любые будущие description rewrites; не урезать ради 900-char budget. Currently 744 chars (156 char headroom). [No code change.]
+- **Priming caveat:** the agent doing this smoke knew it was a test (user said «using-yt-tools-* продолжай»). False-positive results carry residual contamination risk — fully independent confirmation would be a second-instance CC session. 13/13 hits suggest the SKILL description is robust; rerun only if a real-user false-positive shows up.
+
+## Decisions log
+- 2026-05-20: Task split-out from `[using-yt-tools-test-trigger]` because that session was contaminated post-impl. Created per [using-tasks] when activated.
+- 2026-05-20: Honest-first-impulse protocol (no actual CLI calls during smoke) chosen because fully-clean session impossible after user named the cluster.
+
+## Open questions
+- [ ] Если N1/N2/N3 borderline activate — править description? Или принять как ambiguous и оставить юзеру override?
+
+## Completed steps
+- [x] 10 positive phrases tested — 10/10 activate as expected
+- [x] 3 false-positive phrases tested — 3/3 not-activate as expected
+- [x] Findings reviewed — no fix-tasks needed; 2 design notes recorded above
+- [x] Close note appended (in STATUS.md block)
+
+## Notes
+- SKILL.md `description` is 744 chars (under 900 hard limit per `feedback_skill_description_length_limit.md`).
+- Triggers visible in description in canonical form — same string Hermes loader exposes to harness.
+- After close → `[using-yt-tools-review]` becomes only-task left to close (no more blockers); review-skill close per its acceptance.
