Conciseness

The body is lean and prescriptive with zero padding: it assumes APM knowledge (never explains what compaction, a Handoff, or the bus are) and every sentence carries an instruction, matching 'Lean and efficient; assumes Claude's competence; every token earns its place'. It is not a 4 because there is no over-explanation that could be trimmed — even the gating paragraph adds a condition ('or an APM instruction directs you here') beyond the frontmatter.

Actionability

Guidance is concrete and directive — reread '{SKILL_PATH:apm-2-initiate-manager} §1', keep the current prompt's 'log_path', record the recovery in 'the Tracker's Notes' — with both Manager and Worker branches covered, fitting 'Mostly executable guidance; concrete code or commands with minor gaps'. It is not a 5 because key operations resolve through templated placeholders and external structures ({VERSION}, {SKILL_PATH:...}, 'the bus and the code') rather than fully literal, self-contained instructions; not a 3 because no key details are missing for the APM context it targets.

Workflow Clarity

Five numbered steps in a clear sequence with explicit checkpoints — 'If neither settles it, ask' (step 1), 'Ask the User about gaps the files cannot settle' (step 3), and the report-back in step 5 — matching 'Clear sequence with most checkpoints present; minor validation gaps'. It is not a 5 because there is no explicit verification that the rebuilt state matches the pre-loss state before continuing; not a 3 because checkpoints are explicit, not merely implied, and the operation is non-destructive so no cap applies.

Progressive Disclosure

The skill is under 50 lines with no bundle files, and the body is well organized (title, gating, context, numbered procedure) while correctly delegating the file lists to the sibling initiation skills via clearly signaled one-level references ('{SKILL_PATH:apm-2-initiate-manager} §1'), matching both the under-50-lines guideline and 'Clear overview with well-signaled one-level-deep references'. No nesting or buried references exist, so no lower anchor fits.

Specificity

"Recover an APM agent's working context" names the domain (APM agent recovery) and one concrete action, matching the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. It is not a 4 because only a single action is listed (no mention of rebuilding state from files, logs, or the bus), and not a 2 because the action is domain-specific rather than generic.

Completeness

Both parts are answered: the what is "Recover an APM agent's working context" and the when is the explicit clause "Use only when the User manually invokes this skill", matching 'Has both what and when; when could be more explicit or specific'. It is not a 5 because the when-clause is procedural (manual invocation) rather than concrete situational trigger phrases (e.g., after compaction or context loss).

Trigger Term Quality

Relevant keywords are present ("Recover", "APM agent", "working context") but the natural phrases a user would say in the triggering scenarios — "compaction", "lost conversation", "resume" — are absent, fitting 'Some relevant keywords but missing common variations or synonyms'. It is not a 4 because more than a few natural terms are missing.

Distinctiveness Conflict Risk

"APM agent's working context" carves out a clear niche with the distinctive term APM, and the manual-invocation-only condition means it cannot auto-trigger for the wrong skill, matching 'Clear niche with distinct triggers; minimal conflict risk'. No neighboring anchor fits better since no other skill domain is plausibly conflated with APM context recovery.
