Conciseness

Mostly efficient but with real tightening opportunities: the 37-line CAPABILITIES_SUMMARY comment block largely restates capabilities the Core Contract bullets then re-explain (e.g., bottleneck_migration_detection appears in both), routing signals are triple-listed (Trigger Guidance bullets, Recipes table, Output Routing table), and long bullets explain general failure modes Claude already knows ("resource deadlocks (agents blocked on shared resources without timeout — silently consume resources... harder to detect than crashes because they mimic productivity)"). Not 2 because there is no tutorial-style padding; not 4 because the comment/body duplication exceeds 'minor instances of over-explanation'.

Actionability

Concrete specifics exist — persistence targets (".agents/ECOSYSTEM.md"), grade bands "S(95+) A(85+) B(70+) C(55+) D(40+) F(<40)", thresholds ("Confidence ≥0.60", "If EFS drops >5 points within 7 days → flag for review"), an exact PROJECT.md row format, and parseable subcommand dispatch (health/fitness/evolve/sunset). But the core mechanics — EFS formula, RS formula, lifecycle detection algorithm — are entirely delegated to reference files ("You need RS formula, EFS formula, or lifecycle detection algorithm" → reference/assessment-models.md), none of which ship in the bundle. Not 4 because key execution details are missing from what is present; not 2 because thresholds, file formats, and dispatch rules are concrete.

Workflow Clarity

The SENSE → ASSESS → EVOLVE → VERIFY → PERSIST table gives each phase a required action, key rule, and read-file; VERIFY has explicit criteria ("Confirm EFS does not decrease", "If EFS drops >5 points within 7 days → flag for review") plus a feedback loop ("Feed below-threshold production traces back into the evaluation baseline — drift that escapes detection becomes the new normal"); destructive sunset operations are gated behind Ask-First with graceful-deprecation verification; and Output Requirements acts as a checklist ("a ceiling, not a floor"). Not 4 because checkpoints are explicit with error-recovery loops, not merely present.

Progressive Disclosure

Navigation is well signaled — a Reference Map with a "Read this when" column and Read First/Read next columns pointing one level deep — but the bundle ships no references/, scripts/, or assets/ directories, so all 10+ referenced paths (reference/*.md, _common/*.md) are unresolvable as provided, and the 37-line CAPABILITIES_SUMMARY comment block is reference-grade detail inlined directly in SKILL.md. Not 4 because unresolvable referenced paths plus inlined capability detail is more than a minor organization gap; not 2 because structure and reference signaling are present and clear.

Specificity

Names four concrete actions — "lifecycle-phase detection, agent relevance, cross-agent knowledge synthesis, evolution proposals" — matching the 'several specific actions; minor gaps' anchor. Not 5 because the actions stay domain-abstract (no concrete artifacts/objects like file types) and body-supported capabilities such as staleness/sunset detection are absent; not 3 because four actions are named, exceeding the 1–2 of that anchor.

Completeness

Both answered: what = "Orchestrating ecosystem self-evolution: lifecycle-phase detection, agent relevance, cross-agent knowledge synthesis, evolution proposals"; when = "Use when auditing skill-ecosystem health or fitness". Not 5 because the when-clause covers only health/fitness auditing while the body supports many more triggers (sunset identification, drift cascade, sprawl, trigger evaluation), so 'when' could be more explicit; not 3 because the when is explicitly stated, not weakly implied.

Trigger Term Quality

Natural terms present: "auditing skill-ecosystem health or fitness", "agent relevance", "lifecycle-phase detection". Not 5 because common variations the body's own Trigger Guidance lists are missing ("staleness", "sunset", "sprawl", "drift", "journal synthesis"); not 3 because coverage is genuinely good rather than 'some relevant keywords'.

Distinctiveness Conflict Risk

"Orchestrating ecosystem self-evolution" plus "skill-ecosystem health or fitness" carves a clear niche with distinct triggers and minimal conflict risk against generic skills. Not 4 because no evident overlap risk remains — the qualifying term "skill-ecosystem" scopes the otherwise-common words "health" and "fitness" to this niche.
