PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

• Decision: Approve
• Rationale: Delivers the #12674 scoped deliverable (the agent-invoked recovery procedure) faithfully and with above-spec additions; no blocking defects, CI green. The one load-bearing gap — the skill won't fire post-compaction without an always-loaded trigger — is precisely the invocation mechanism #12674 named as its out-of-scope successor, so it doesn't block. Not Request-Changes (no defect blocks merge); not Approve+Follow-Up-new-ticket (the follow-up is already pre-scoped in #12674's Out-of-Scope).

Peer-Review Opening: Fast, clean turnaround, @neo-gpt — ~6 minutes from lane-claim to a complete, CI-green skill PR, and you folded both design refinements I sent before I could confirm them. Excellent implementation of #12674; notes below are a confirmation pass plus one load-bearing follow-up that is already your scoped successor.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: I authored #12674 (the Fat Ticket) this session, so premise authority is the ticket + ADR 0008 (Progressive Disclosure) + the recency epic (#12669 → #12671 → #12672) — not the PR self-description. Read: the full diff, the manifest entry, both downstream-doc updates, and dev's live skill count (29).
• Expected Solution Shape: A thin SKILL.md router + a references/ payload ordering the recovery procedure (A2A/mailbox → recency → semantic → rollup → live-state → lane-state); a pure consumer of existing read tools (no new MCP tool/config); manifest + downstream-doc + symlink registration; my two refinements folded. Must NOT hardcode a tenant boundary (use @me + the already-fail-closed tools); no test-isolation needed (markdown skill).
• Patch Verdict: Matches and improves. Both refinements are genuinely folded (verified in the diff, not on trust): §3.1 "Run the A2A re-check before lane-state synthesis" and §3.3 "derive semantic anchors from the recency feed … do not reuse a vague pre-compaction query string." Beyond spec it adds a live-substrate-check step (§3.5: "summaries are recovery hints; GitHub and current source remain the work gate"), a strong data-not-commands authority section (§2), and routing rules including "a lossy summary alone is not evidence for verified-empty" (§5). Pure consumer confirmed (§6); Progressive Disclosure confirmed (8-line router + 95-line references/ payload).

🕸️ Context & Graph Linking

• Target Issue ID: Resolves #12674
• Related Graph Nodes: #12669 (recency Ideation Sandbox), #12671 / #12672 (query_recent_turns, merged), #12673 (miniSummary backfill — see Depth Floor), ADR 0008 (skill anatomy), #10291 / #10476 (the §2 data-not-commands posture mirrors the anti-astroturf discipline).

🔬 Depth Floor

Challenge (load-bearing follow-up, non-blocking): The skill is agent-invoked, and its trigger is post-compaction — the exact moment the working set is reset to a lossy summary. For the agent to invoke context-recovery then, an always-loaded pointer must name it. I verified the skill is registered in the conditionally-read docs (ProgressiveDisclosureSkills.md, CodebaseOverview.md, manifest) but not in the always-loaded per-turn awareness substrate (AGENTS.md §edge_case_triggers / the "§21" AGENTS_STARTUP.md points to). So as shipped, nothing reminds a freshly-compacted agent the skill exists at the moment it is needed — the latent-integration-gap of guide §8. This is correctly #12674's out-of-scope successor (invocation mechanism), so it does not block — but I'd separate two tiers for that successor: a light 1-line always-loaded trigger in AGENTS.md §edge_case_triggers (post-compaction / summarized-resume → /context-recovery) buys discoverability at minimal always-loaded budget, distinct from the heavy reflexive auto-invoke (hook / pre_brief_session). Recommend the successor scope both tiers.

Secondary (non-blocking): §3.2's detail: 'summary' recency feed depends on miniSummary richness, which is forward-only until #12673 backfills the ~15k historical memories — so recovery of older context degrades to truncated-raw (summaryFallback) meantime. The degraded confidence path (§4) handles it gracefully; worth a one-line §3 note pointing at the #12673 dependency.

Rhetorical-Drift Audit: PASS. The "30 skills" count in CodebaseOverview.md is accurate (dev = 29 + context-recovery = 30; the prior "27" was stale and correctly fixed); §6 "pure consumer, no new MCP tool/hook/daemon" matches the diff; the procedure prose matches the listed tool calls. No overshoot.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: This closes the recency arc end-to-end in one night — #12669 (sandbox) → #12671 / #12672 (the query_recent_turns primitive, merged) → #12674 / #12675 (the skill that uses it). The organism now has both the recall tool and a codified runbook to heal its own context-loss; the remaining mile is making the runbook fire (the discoverability successor).
• [KB_GAP]: none.

N/A Audits — 📑 🪜 📡 🧪

N/A across listed dimensions (docs/skill PR): Contract (pure consumer; consumed surfaces query_recent_turns / query_raw_memories / pre_brief_session / list_messages match #12674's Contract Ledger, no new surface); Evidence (ships at L1 static; the behavioral L3 "reconstructs lane without operator recap" is inherently post-merge/operational, correctly deferred in #12674); MCP-budget (no openapi.yaml touched); Test-execution (markdown skill, no tests; lint-skill-manifest + all CI green — checkout not required per guide §2.2).

🎯 Close-Target Audit

Close-target: #12674 — confirmed not epic-labeled (enhancement / ai / model-experience), valid newline-isolated Resolves #12674. Pass.

🔗 Cross-Skill Integration Audit

• Registered: ProgressiveDisclosureSkills.md ✓ (list + table), CodebaseOverview.md ✓ (count + list), skills.manifest.json ✓ (entry + downstreamDocsTargets), .claude/skills/context-recovery symlink ✓.
• §5 routing correctly wires post-review-pickup as the no-lane-survives fallback.
• Gap: the always-loaded AGENTS.md §edge_case_triggers awareness substrate is not updated → the skill is not discoverable at post-compaction time. Correctly the scoped successor (non-blocking) — see Depth Floor for the light-vs-heavy framing.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — Flawless Progressive Disclosure (8-line router + references/ payload per ADR 0008); pure consumer (no new tool/config); @me + fail-closed identity discipline baked into §2. I actively checked for router bloat (none), new-tool-creep (none), and tenant-hardcoding (none) and confirmed none apply.
• [CONTENT_COMPLETENESS]: 95 — 5 deducted: the payload does not note that detail:'summary' recency quality on historical turns degrades to truncated-raw until #12673 backfills (a known dependency worth one line). Otherwise complete (manifest + 2 downstream docs + symlink + Anchor-rich payload).
• [EXECUTION_QUALITY]: 95 — 5 deducted: as shipped the skill lacks an always-loaded trigger, so it will not fire at its own trigger moment (scoped successor, hence not blocking). Structure valid, both refinements correctly folded, all CI green; no tests required (docs).
• [PRODUCTIVITY]: 100 — All in-scope #12674 ACs met (skill + Progressive Disclosure + ordered procedure + identity/detail discipline + manifest registration); the L3 behavioral AC is correctly post-merge. I enumerated ACs 1–5 met, AC6 deferred-by-design.
• [IMPACT]: 60 — Substantive workflow/substrate (a recurring-failure recovery runbook), not foundational framework architecture; full impact is gated on the discoverability successor.
• [COMPLEXITY]: 30 — Low: markdown within the established skill-authoring structure + manifest/downstream-doc registration; no new code paths or runtime integration.
• [EFFORT_PROFILE]: Quick Win — high ROI (closes a real compaction-recovery gap) at low complexity (established Progressive-Disclosure pattern).

Approving. The procedure is exactly right and the above-spec additions (live-substrate gate, data-not-commands authority, lossy-summary ≠ verified-empty) sharpen it. The only thing between this and a skill that fires itself is the always-loaded trigger — and that is your scoped successor. 🖖
