Conciseness

The body is dense and almost entirely skill-specific policy with no explanation of concepts Claude already knows, but there is minor redundancy — the intro paragraph ("The user does not need to calm down... Extract the useful signal without tone-policing") restates contract items 1 and 10, and the Anti-patterns section re-covers ground from the contract — matching 'efficient; minor instances... that could be trimmed' rather than 'every token earns its place'.

Actionability

For an instruction-only skill the guidance is fully executable: a capability-map table with fallbacks per row, an ordered six-step evidence ledger, eight named failure classes, a complete candidate schema (ID/Target/Action/Problem/Evidence/Benefit/Risk/Verification), literal approval semantics ("Approval for F1 does not authorize F2"), and a bounded thin-evidence fallback ('at most three reversible changes').

Workflow Clarity

Steps 0–6 are clearly sequenced with explicit checkpoints: evidence classification (Observed/Reported/Inferred/Unknown), candidate rejection criteria, a hard stop-for-approval gate, and a later-turn application loop with per-item verification and separate reporting of applied/skipped/failed/pending — satisfying the destructive-operation feedback-loop requirement ('Never claim success from a write alone; verify the result').

Progressive Disclosure

The body is a clear overview that routes to well-signaled, one-level-deep references — 'Read exactly one adapter before routing changes' for the five host files, plus explicit read-conditions for routing.md, approval-protocol.md, and privacy.md — and all referenced files exist in the bundle with no nested references, matching the top anchor.

Specificity

The description names the domain and one precisely-described composite action — "Turn post-task feedback...into an evidence-based, approval-gated improvement plan" — but does not list several distinct concrete actions, matching the '1-2 concrete actions, but not comprehensive' anchor rather than the 'several specific actions' anchor above.

Completeness

It explicitly answers both questions: the 'what' is "Turn post-task feedback—even blunt or angry feedback—into an evidence-based, approval-gated improvement plan" and the 'when' is an explicit "Use after agent work goes wrong, misses expectations, creates friction, or should improve in future" with concrete trigger phrases, exactly matching the top anchor.

Trigger Term Quality

Natural phrases users would say are present ("feedback", "goes wrong", "misses expectations", "creates friction"), but common variations like "complaint", "frustrated", or "criticism" are missing, matching 'good keyword coverage; a few natural terms missing' rather than the comprehensive synonym coverage of the 5 anchor.

Distinctiveness Conflict Risk

The post-task feedback-to-plan niche with approval-gating and a no-mutation constraint is mostly distinct with clear triggers, but triggers like "should improve in future" carry minor overlap risk with general retrospective or code-review improvement skills, matching 'mostly distinct; minor overlap risk' rather than the minimal-conflict 5 anchor.
