Conciseness

The body is dense and operational — command blocks, weighted-dimension tables, metric targets, and numbered workflows — and does not re-explain concepts Claude already knows (no "what is Scrum" padding), matching the score-4 anchor of efficient with minor trimmable content. It falls short of score 5 because the opening self-description paragraph, the 7-line Table of Contents, the "Related Skills" section, and the closing italic pointer line are meta-content that could be trimmed or merged.

Actionability

Guidance is highly concrete: exact bash invocations per script, a JSON input schema, expected-output values ("velocity avg 20.2 pts, CV 12.7%, health score 78.3/100, action-item completion 46.7%"), and numeric decision rules ("70% confidence interval as the recommended commitment ceiling", "≤3 if completion rate <60%"). It is not score 5 because the commands are not fully executable as delivered — the cited script files (scripts/velocity_analyzer.py etc.) are absent from the bundle, and some invocations drop the scripts/ path prefix. It is well above score 3 since everything written is specific and runnable in principle.

Workflow Clarity

The Sprint Execution and Team Development workflows are clearly sequenced with explicit validation checkpoints and escalation loops: "If fewer than 3 sprints are present... stop and prompt the user", "If a blocker is unresolved after 2 days, escalate proactively", "If scores plateau or regress for 2 consecutive sprints, escalate intervention strategy", plus per-script data requirements. This matches the score-5 anchor of clear sequences with explicit validation and feedback loops; there are no missing checkpoints.

Progressive Disclosure

The SKILL.md is structured as a proper overview with clearly signaled one-level-deep references ("details in references/team-dynamics-framework.md", "See assets/sample_sprint_data.json"), which alone would rate 4-5. However, none of the referenced files exist in the bundle — scripts/, references/, and assets/ are absent entirely — so every pointer dangles and the disclosure structure does not actually function. Score 3 reflects good on-page organization undermined by a broken referenced structure; not score 2 because the SKILL.md body itself still contains substantial inline usable content rather than deferring everything to the missing files.

Specificity

The description lists multiple concrete actions with named tools and outputs: "Runs Python scripts to analyse sprint JSON exports from Jira", naming velocity_analyzer.py "for Monte Carlo sprint forecasting", sprint_health_scorer.py "for multi-dimension health scoring", and retrospective_analyzer.py "for action-item and theme tracking", plus concrete outputs ("confidence-interval forecasts, health grade reports"). This matches the score-5 anchor of multiple specific concrete actions with comprehensive coverage; it is well above score 4 because there are no meaningful gaps in capability coverage.

Completeness

It explicitly answers both questions: "what" ("Runs Python scripts to analyse sprint JSON exports... Produces confidence-interval forecasts, health grade reports, and improvement-velocity trends") and "when" ("Use when the user asks about sprint planning, velocity tracking, retrospectives...") with concrete trigger phrases. This is the score-5 anchor exactly; it is not score 4 because the "when" clause is fully explicit rather than improvable.

Trigger Term Quality

Trigger coverage is comprehensive and natural: "sprint planning, velocity tracking, retrospectives, standup facilitation, backlog grooming, story points, burndown charts, blocker resolution, or agile team health", plus "Jira" and "sprint JSON exports". These are phrases a user would actually say, including synonyms (standup facilitation, burndown charts) and tool names, matching the score-5 anchor; it exceeds score 4 because no common variation is obviously missing.

Distinctiveness Conflict Risk

The niche (data-driven Scrum Master analytics over sprint JSON exports) is mostly distinct with clear scrum-facilitation triggers, matching the score-4 anchor "mostly distinct; minor overlap risk with closely related skills": terms like "backlog grooming", "sprint planning", and "agile team health" overlap with product-owner and general agile-coaching skills. It falls short of score 5 because conflict risk with closely adjacent agile skills is more than minimal.
