Conciseness

The body is instruction-dense and assumes Claude's competence — no padded explanations of what a session or retrospective is. It earns a 4 rather than 5 because the Guardrails section partly restates earlier guidance (e.g., 'Do not exaggerate routine exploration into a systemic problem' and 'Do not hide the agent's own errors behind tooling or instruction complaints' echo points already made above), which could be trimmed. Not below 4: there is no verbosity explaining concepts Claude already knows.

Actionability

Guidance is concrete and specific: named finding categories, an exact report section list with per-section content, priority labels (now/soon/only if repeated), and specific checks ('inspect working-tree status and the changed-file summary'). It stops at 4 because, for an instruction-only skill, one worked example of a classified finding paired with a proposed improvement would make the format fully tangible. Not below 4: the guidance is already mostly executable, not abstract.

Workflow Clarity

A clear multi-step sequence (Interrogate → Classify → Recommend → Report) with explicit verification checkpoints: 'Verify the factual premise behind user questions', 'perform only the cheap read-only checks needed to confirm the current state', and reconciliation with recorded verification. Error-handling guidance is present ('State when relevant evidence is unavailable'; 'Say No material friction observed when that is the honest conclusion'). Not below 5: checkpoints are explicit, not merely implicit. The destructive/batch cap does not apply because the skill is explicitly propose-only.

Progressive Disclosure

A single self-contained SKILL.md with well-organized section headers (Interrogate, Classify, Recommend, Report Format, Guardrails) and no nested external references; no bundle files are present or needed. Not below 5: navigation via headers is clear and all content belongs inline as core guidance.

Specificity

Lists multiple concrete actions — 'identify friction, mistakes, near misses, missing context, and opportunities to improve future work' and 'Produce an evidence-based, propose-only report' — giving comprehensive coverage of what the skill does. Not below 5: coverage is not merely 'several actions with minor gaps'; it enumerates the full set of outputs the skill produces.

Completeness

Explicitly answers both 'what' ('Review a completed, paused, or blocked coding-agent session to identify ...') and 'when' ('Use when the user asks to wrap up, run a retrospective ...') with concrete trigger phrases. Not below 5: the when-clause is explicit and specific, not merely weakly implied.

Trigger Term Quality

Natural user-facing phrases are comprehensive and include synonyms: 'wrap up', 'run a retrospective', 'explain what issues the agent faced', 'capture lessons learned', and 'recommend improvements to ... documentation, skills, tooling, tests, or workflows'. Not below 5: these are exactly the terms a user would say, with common variations covered.

Distinctiveness Conflict Risk

Occupies a clear niche — session retrospectives / wrap-ups — with distinct triggers ('wrap up', 'retrospective', 'lessons learned') unlikely to fire for unrelated skills. Not below 5: overlap with general code-review or commit-message skills is minimal given the retrospective framing.
