Conciseness

The body is lean and directive throughout — 'Gather a concise diagnostic. Do not over-investigate.' sets the tone, and every line carries an instruction, command, path, or template field with zero explanation of concepts Claude already knows. It matches the 'every token earns its place' anchor and is clearly above the minor-over-explanation level 4.

Actionability

Concrete executable commands are given for most steps (`basic-memory --version`, fallback `bm --version`, `uvx --prerelease=allow basic-memory --version`, `basic-memory hook status --harness codex --project-dir <repo-root>`, `~/.codex/basic-memory.json`) plus a copy-paste-ready presentation template. It falls short of fully executable because step 5 says 'query recent `type=codex_session`' without specifying the actual query command/syntax, and the `../../README.md` pointer references a file outside the skill bundle that cannot be verified from the skill itself.

Workflow Clarity

The Gather steps are a clear numbered 1-5 sequence with explicit fallback and validation checkpoints: 'Keep going if no launcher resolves', 'if it disagrees with the manually read config, show the mismatch', 'never run an unscoped coding-session query when the repository is missing', and 'only report Desktop hook execution as verified when startup context and a post-compaction checkpoint note were observed'. This is a read-only diagnostic skill with error-handling branches and a rigid output checklist, matching the top anchor rather than the minor-validation-gaps level 4.

Progressive Disclosure

The body has good structure (Gather / Present sections, an exact output template) and its one reference is clearly signaled at a single level ('consult `../../README.md` under "Troubleshooting Desktop hooks on WSL"'), while the bundle (only `assets/icon.svg`, no references/ or scripts/) appropriately keeps everything inline for a ~95-line skill. It is not a 5 because the README pointer resolves outside the skill bundle and the WSL troubleshooting detail it defers to is not available as a bundled reference — a minor organization gap rather than the clean one-level-deep ideal.

Specificity

The description lists several distinct reporting targets — 'configuration, reachability, hook expectations, recent Codex checkpoints, and active tasks' — which matches the anchor for several specific actions with minor gaps. It is not a 5 because 'reachability' and 'hook expectations' are semi-abstract rather than fully concrete actions, and not a 3 because it goes well beyond 1-2 concrete actions.

Completeness

The 'what' is clearly stated (report configuration, reachability, hook expectations, checkpoints, tasks), but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description. Per the judging guidelines, a missing 'when' clause caps completeness at 3; it is above 2 because the 'what' is concrete and unambiguous.

Trigger Term Quality

It includes some relevant keywords users would naturally say ('Basic Memory', 'Codex', 'checkpoints', 'active tasks'), but 'reachability' and 'hook expectations' are developer jargon rather than natural user phrasing, and common variations or synonyms a user might type (e.g. 'is basic memory working', 'bm status', 'hooks not running') are absent. This fits the 'some relevant keywords but missing common variations' anchor, not the good-coverage anchor above it.

Distinctiveness Conflict Risk

'Basic Memory for Codex' names a specific tool and harness, giving the skill a clear niche with triggers ('basic memory', 'Codex hooks', 'checkpoints') that are unlikely to fire for unrelated skills. It fits the clear-niche/minimal-conflict anchor better than the 'mostly distinct with minor overlap' anchor below it, since the tool name alone disambiguates.
