Conciseness

The ~40-line body is lean with no explanations of concepts Claude already knows and a tight JSON example, but the intro paragraph ("After you have modified the skill's source files... you MUST update the `manifest.json`") duplicates step 3 of the procedure, and "The UI will automatically detect this change and refresh" is incidental — minor instances that could be trimmed, matching anchor 4. Not 5 because of that duplicated instruction and the incidental UI note.

Actionability

The manifest update is fully concrete — "Find the entry for the skill ID in the `skills` object", "Set `\"status\": \"installed\"`", "Clear the `\"error\"` field (set to `null` or remove it)" — with a copy-paste-ready JSON example, but the core repair guidance ("analyze them collectively to find the root cause", "Understand the error message provided in the prompt") gives direction without executable method, leaving minor gaps — anchor 4. Not 5 because the fix step, the heart of the workflow, has no concrete procedure or example.

Workflow Clarity

The four-step sequence (Analyze Error → Fix Installed Path → Update Manifest → Verification) is clearly ordered, but "Verification: The UI will automatically detect this change and refresh" is a passive claim rather than an agent-performed checkpoint — no step validates that the fix actually resolved the error before the skill is marked "installed". For a workflow that modifies skill files and the manifest, this missing feedback loop caps the score at 3 per the rubric's destructive/batch guidance. Not 4 because the one validation step that exists is not actionable by the agent.

Progressive Disclosure

The skill is under 50 lines, single-purpose, and needs no external references (no references/, scripts/, or assets/ exist, and none are required); sections ("Skill Context", "Repair Procedure", "Manifest Example") are well-organized and the manifest example is appropriately inline — meeting the simple-skill exception for a 5. Not below 5 because nothing here warrants splitting into bundle files.

Specificity

Names concrete actions — "fix and re-install agent skills that have failed installation" and "surgically update the `manifest.json`" — but "provides the necessary context and permissions" is abstract filler, and the second-person/imperative opening "Use this to..." (rather than third person like "Fixes and re-installs...") incurs the 1-point voice penalty, dropping an anchor-4 fit to 3. Not a 2 because the domain and the manifest-update action are explicitly named.

Completeness

The "what" is clear ("fix and re-install agent skills that have failed installation", "update the `manifest.json`") and the "when" is explicitly stated via "skills that have failed installation" — so the missing-trigger-clause cap does not apply — but the condition is embedded in a purpose statement ("Use this to fix...") rather than an explicit "Use when..." clause, fitting anchor 4 ("'when' could be more explicit or specific"). Not 5 because there is no distinct trigger clause with concrete trigger phrases.

Trigger Term Quality

"fix", "re-install", "failed installation", and "skills" are phrases a user with a broken install would plausibly say, but common variations and synonyms — "broken", "error", "failed to install", "skill not loading" — are absent, matching anchor 3 ("some relevant keywords but missing common variations"). Not 4 because coverage of natural phrasings is thin for the failure/repair vocabulary.

Distinctiveness Conflict Risk

"failed installation", "re-install", and "`manifest.json`" define a clear niche with mostly distinct triggers, but "fix... agent skills" alone could overlap with general skill-editing or skill-debugging requests, giving minor overlap risk with closely related skills — anchor 4. Not 5 because the broad verb "fix" applied to "agent skills" is not uniquely tied to installation repair.
