Conciseness

The body is efficient — compact tables ('What Survives Compaction', 'Compaction Decision Guide') and a copy-paste hook config — with only minor over-explanation, e.g. 'Auto-compaction triggers at arbitrary points... No awareness of logical task boundaries' restates behavior Claude already knows. Not 3 because padding is isolated to one section; not 5 because 'Why Strategic Compaction?' and parts of 'Best Practices' could be trimmed.

Actionability

Concrete elements exist (the settings.json hook block, COMPACT_THRESHOLD env var, '/compact Focus on implementing auth middleware next'), but the core mechanism 'node ~/.claude/skills/strategic-compact/suggest-compact.js' references a script that is not bundled in the skill, leaving the primary executable path incomplete. Not 4 because a missing key script is more than a minor gap.

Workflow Clarity

As an advisory skill it provides a clear decision workflow — the phase-transition table ('Research → Planning | Yes', 'Mid-implementation | No') plus the checkpoint 'The hook tells you when, you decide if' — with most decision points explicit. Not 5 because there is no guidance on recovering when compaction discards something still needed; not 3 because sequence and decision checkpoints are present and unambiguous for a non-destructive task.

Progressive Disclosure

Single-file skill with well-organized sections and no nested or buried references; the 'Related' section points to clearly labeled external resources. Not 5 because at ~100 lines the persistence/survives tables are borderline content that could live in a reference file, keeping the overview leaner.

Specificity

Phrases like 'Suggests manual context compaction at logical intervals' name the domain and one concrete action, matching the anchor for 1-2 concrete actions without comprehensive coverage. Not 4 because no further specific actions (hook, threshold tracking, /compact usage) are listed; not 2 because the action stated is concrete rather than generic.

Completeness

The 'what' is clear ('Suggests manual context compaction at logical intervals') but the 'when' is only weakly implied through 'task phases rather than arbitrary auto-compaction' — there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the rubric guidelines. Not 4 because no explicit usage condition is stated at all.

Trigger Term Quality

Relevant keywords are present ('manual context compaction', 'auto-compaction', 'task phases') but natural user phrases are missing — users would say 'compact', '/compact', 'context window is filling up', or 'long session', none of which appear. This matches 'some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

Context compaction is a clear niche ('preserve context through task phases rather than arbitrary auto-compaction') that is easily distinguishable from most skills, with only minor overlap risk against memory/persistence-type skills. Not 5 because without explicit trigger phrases the boundary with those adjacent skills is somewhat blurred.
