Conciseness

Largely lean, imperative, and free of concept explanations Claude already knows — it documents only repo-specific rules (ledger layout, grouping authority, parallel-safety). Not 5 because the strict-1:1 spawn rule is restated at least three times ('never one subagent told to handle several groups and never sequential', 'Never one subagent handed multiple Group Plans; never sequential spawning', plus the anti-patterns list) and several Grouping Rule constraints are repeated in later sections. Not 3 because there is no conceptual padding or unnecessary explanation.

Actionability

Copy-paste-ready commands throughout: the exact `pnpm exec sentry-cli issues list` invocations, an executable bash/jq ledger-filter loop, the dedupe script call with env vars, a fill-in Group Plan template, and a uniform spawn prompt template. Ledger required-fields and branch-naming rules are concrete. Common cases are covered end-to-end; the only soft spot ('an authenticated project-approved Sentry command') is a justified flexibility escape hatch, not pseudocode.

Workflow Clarity

The three-phase sequence (Fetch → Ledger Filter → Existing-PR Dedupe → Grouping → Spawn → Parent Reconciliation) is clearly ordered with explicit checkpoints for a batch operation: 'If the script exits non-zero ... halt the run and ask a human', the post-run ledger collision check via `gh pr view --json files`, the subagent stop-and-return-findings loop for disproved groups, and the skip-if-terminal ledger rule. Matches the top anchor with feedback loops for error recovery.

Progressive Disclosure

Good structure: well-organized sections with internal anchor links, and subagent decision rules correctly delegated one level deep to SUBAGENT_CONTRACT.md ('Subagent rules live in SUBAGENT_CONTRACT.md', 'Full decision rules live in SUBAGENT_CONTRACT.md'). Not 5 because the skill is a single ~220-line file with no bundle references of its own — the ledger record schema and dedupe-script internals are inlined and could live in a referenced file. Not 3 because the split that does exist is clearly signaled and one level deep, and the inline content is operational (workflow rules) rather than reference material that blocks navigation.

Specificity

The description names the domain ('Fern CLI Sentry false-positive triage for buildwithfern/cli') and lists multiple concrete actions: 'investigating Sentry CLI issues, classifying false positives, updating the triage ledger, or creating PRs for Sentry error fixes' — comprehensive coverage of the skill's capabilities with no padding. Not 4 because the action list covers everything the skill does (investigate, classify, ledger, PR), matching the 'comprehensive coverage' anchor.

Completeness

Explicitly answers both: what — 'Run Fern CLI Sentry false-positive triage for buildwithfern/cli' — and when — 'Use when investigating Sentry CLI issues, classifying false positives, updating the triage ledger, or creating PRs for Sentry error fixes' with concrete trigger phrases. Clearly matches the top anchor; not 4 because the 'when' clause is fully explicit, not merely adequate.

Trigger Term Quality

Natural phrases a user would say are present: 'Sentry CLI issues', 'classifying false positives', 'triage ledger', 'creating PRs for Sentry error fixes'. Not 5 because a few common synonyms/variants are missing (e.g., 'Sentry alerts', 'error reports', 'noise', 'triaging'); not 3 because coverage goes well beyond one generic keyword.

Distinctiveness Conflict Risk

Clear niche: Sentry false-positive triage scoped to a specific org ('buildwithfern') and project ('cli') with a distinct workflow (ledger updates, triage PRs). Triggers are specific enough that it would not fire for unrelated Sentry, bug-triage, or general PR skills; minimal conflict risk.
