Conciseness

Mostly efficient org-specific deltas, but date-stamped provenance is inlined rather than quarantined — "the July 2026 consolidation retired the old `v0`/`post-v0` scope labels", "(Jul 26 2026…)", "(verified 2026-07-26 while filing #646/#647)", "this is how #416 slipped in" — plus a long aside about `updateProjectV2Field` renaming and grouped views. Not 4 because these are several trimmable instances of time-sensitive/over-explanatory material, exceeding 'minor' over-explanation.

Actionability

Gives a copy-paste-ready sweep pipeline (`gh project item-list 1 --owner alethical-org --format json --limit 200 | jq …`), exact flags (`--label`, `--milestone`), named GraphQL mutations (`updateProjectV2ItemFieldValue`, `addProjectV2ItemById`, `addSubIssue`), and a spot-check command (`gh issue list --json number,issueType`). Not 5 because the core step-two board-field write is described ("query the project's field/option IDs with `gh api graphql`") but never shown as an executable example.

Workflow Clarity

The create-then-set-board-fields sequence is explicit with a clear failure tell ("An issue that lands in 'No Epic' or with a blank Priority/LOE/Type"), a self-healing validation backstop ("run the sweep and fix whatever it lists"), and a lifecycle checklist. Not 5 because the GraphQL half lacks an explicit validate→fix→retry checkpoint; its verification is implicit in the sweep.

Progressive Disclosure

Well-organized headed sections, one-level-deep external pointer (`.claude/rules/workflow.md`), no nested references, and no bundle files to misplace. Not 5 because the ~60-line body exceeds the under-50-line simple-skill bar and inlines the dense 8-axis reference material that could live in a `references/` file.

Specificity

Lists multiple concrete capabilities — "creating, categorizing, re-scoping, or sweeping GitHub issues", "the full 8-axis scheme (Type, Milestone, Epic, Platform Track, Priority, LOE, topic labels, Status)", "the two-step create-then-set-board-fields gotcha", "the uncategorized-item sweep command", and "the keep-the-board-current lifecycle rules" — comprehensively covering the skill's scope. Not 4 because there are no meaningful coverage gaps.

Completeness

Explicitly answers both: what (the 8-axis scheme, two-step gotcha, sweep command, lifecycle rules) and when ("Use when creating, categorizing, re-scoping, or sweeping GitHub issues…" and "Invoke before `gh issue create`, when moving an issue's Status, or when starting a session and sweeping the board"). Not 4 because the when-clause is explicit with concrete triggers, not merely present.

Trigger Term Quality

Good natural keywords users would say: "GitHub issues", "gh issue create", "moving an issue's Status", "sweeping the board", "starting a session". Not 5 because common variations such as "file an issue", "triage", or "project board" are missing.

Distinctiveness Conflict Risk

Pinned to a specific niche — "Alethical's Roadmap board (org `alethical-org` Project #1)" — with distinct triggers, so it is unlikely to fire for any unrelated skill. Not 4 because there is no realistic overlap with generic issue/labeling skills given the org-specific scoping.
