Conciseness

Nearly all content is non-obvious, team-specific guidance (classification policy, Slack mrkdwn quirks like 'an underscore would close the italics mid-paragraph', ordering rules) that Claude could not infer, so it earns its tokens. Minor over-explanation remains — the model-catalog rule is stated in the Task bucket, again in its own bolded paragraph, and a third time as decision-order step 2 — so it fits 'efficient; minor instances that could be trimmed' rather than the lean anchor.

Actionability

Fully executable throughout: 'python3 .agents/skills/release-digest/scripts/gather_changes.py > /tmp/release_digest.json', the exact JSON output fields (prs[], direct_commits[], excluded_prs[], unresolved_prs[]), a complete copy-paste Slack message template, the channel ID 'C0BDGTGBL4Q', and the exact MCP tool name 'mcp__claude_ai_Slack__slack_send_message'. Matches the fully executable, common-cases-covered anchor.

Workflow Clarity

Four clearly sequenced phases with explicit validation checkpoints and feedback loops: 'If pr_count is 0 AND direct_commits is empty ... Do not post to Slack. Stop here', 'If non-empty, the change set is partial — tell the user which PRs couldn't load before posting', 'Show the composed message to the user and get confirmation before posting', plus a closing checklist. This is a batch/outward-facing operation and validation is present, so the cap at 3 does not apply.

Progressive Disclosure

The body is well-sectioned (Phase 1-4, Checklist) and the mechanical work is correctly externalized into the real bundle file scripts/gather_changes.py (verified to exist and match its in-body description), referenced one level deep. Minor gap: the full gather-output JSON schema and the long classification policy are inlined rather than split into a reference file, keeping it just below the 'clear overview with well-signaled references' anchor.

Specificity

Quotes: "Post a 'what's changed since the last release' recap to the release Slack channel", "Groups merged PRs by author and classifies each as feature / bug fix / task". Multiple specific concrete actions that comprehensively cover what the skill does, matching the anchor for comprehensive coverage; a score of 4 would require a noticeable gap in action coverage, which is absent.

Completeness

Quotes the what ("Post a ... recap to the release Slack channel ... Groups merged PRs by author and classifies each") and an explicit when ("Use when the user wants a release recap, a changelog since the last tag, or to prep QA before cutting a release from main"). Both what and when are clearly and explicitly answered with concrete trigger phrases; a 4 would require the when to be less explicit.

Trigger Term Quality

Quotes: "release recap", "a changelog since the last tag", "prep QA before cutting a release from main". Good keyword coverage with natural phrases users would say, but a few common synonyms are missing (e.g. "release notes", "what's new"), so it fits 'good coverage; a few natural terms missing' rather than the comprehensive anchor.

Distinctiveness Conflict Risk

Quotes: "what's changed since the last release", "recap to the release Slack channel", "changelog since the last tag". A clear niche (pre-release recaps posted to a specific release channel) with distinct triggers and minimal conflict risk with generic changelog or git-log skills.
