Conciseness

The body is dense with actionable instructions — concrete paths, commands, decision options — with almost no explanation of concepts Claude already knows. It is not a 5 because a few passages are persuasive rationale rather than instruction, notably the observed-failure anecdotes in the "Insufficient input" section ("an asset audit returning COMPLIANT on a project with no assets...") that could be trimmed to one line.

Actionability

Guidance is fully executable: exact glob patterns and file locations (e.g., `production/retrospectives/retro-[sprint-slug]-*.md`), a runnable git log command, a complete copy-paste-ready report template with every column defined, and literal AskUserQuestion prompts with enumerated options [A]/[B]/[C]. Not a 4 because the specific examples cover the common sprint and milestone cases end-to-end.

Workflow Clarity

Six clearly sequenced phases with explicit validation checkpoints: the FOUND/ABSENT input checklist before any report is produced, the existing-retrospective check in Phase 1b, discrepancy checking between sprint-status.yaml and the sprint plan, and permission asks before every write (including the archive rename). Error-recovery paths are explicit (BLOCKED verdicts, manual-data fallback, NOT ASSESSED sections). It is not a 4 because no meaningful checkpoint is missing or implicit.

Progressive Disclosure

A single-file skill with well-organized section headers and content appropriately placed inline (the report template is the core deliverable and belongs in SKILL.md); no bundle files exist to reference, and no content is inlined that clearly belongs in a separate file. It is not a 5 because the skill exceeds simple-skill size and the full template plus rationale makes the file longer than an ideal overview-first structure, though nothing warrants extraction.

Specificity

The description names a concrete deliverable ("Sprint or milestone retrospective") and lists specific elements it covers — "completed work, velocity, blockers" — plus a concrete output ("Actionable insights for the next iteration"). It falls short of a 5 because the coverage is fragment-style rather than enumerating multiple distinct actions, and above 3 because more than 1-2 concrete capabilities are named.

Completeness

The "what" is clear (generates a sprint/milestone retrospective with actionable insights), but there is no "Use when..." clause or equivalent explicit trigger guidance, capping completeness at 3 per the judging guidelines. It is not a 2 because the "what" is concrete and specific, not vague.

Trigger Term Quality

Natural terms users would say are present: "sprint", "milestone", "retrospective", "velocity", "blockers". A 5 would require synonyms and variations users commonly type (e.g., "retro", "sprint review", "post-mortem"), which are missing; a 3 would mean missing common variations entirely, but the core vocabulary here is well-chosen.

Distinctiveness Conflict Risk

The sprint/milestone retrospective niche is fairly distinct with specific triggers (velocity, blockers, next iteration). It is not a 5 because it could overlap with adjacent planning skills (sprint planning, sprint status, milestone review) in the same workflow ecosystem; it is well above 3 since the retrospective framing is unmistakable.
