Conciseness

The body is ~68 lines of dense, repo-specific knowledge (just commands, file-category tables, model-port checklists) with no padding and no explanation of concepts Claude already knows — every token earns its place.

Actionability

Mostly executable, copy-paste-ready commands (`just lint`, `just test-fast`, `just ci-extract`, the MFLUX_PRESERVE_TEST_OUTPUT pytest invocation, the `du -sh`/`mflux-save` measurement block), but 'List files changed outside src/mflux/models/<model>/' omits the git command and commit-message guidance ('consistent with repo history') stays abstract.

Workflow Clarity

Validation checkpoints are explicit (lint, golden tests, CI release-note check) and there is a real feedback loop ('If the check fails on an open PR, use the mflux-pr-docs skill again... The check runs again on an edit'), but the top-level commit→push→open-PR sequence is only implied rather than laid out stepwise in the body. Not 5 because the core sequence relies on the description rather than being sequenced here; not 3 because checkpoints and error recovery are explicit and concrete.

Progressive Disclosure

No bundle files exist, and the body appropriately delegates detail one level deep to clearly signaled sibling skills ('use the mflux-pr-docs skill to write the PR body', 'see mflux-model-porting → Integration surfaces checklist') while keeping compact inline checklists; sections are well organized and easy to navigate.

Specificity

'inspect diff, quick verification, commit, push, open PR' lists several specific concrete actions, but 'quick verification' is generic and the required PR-body/release-note step (a CI-enforced part of the workflow per the body) is missing from the description. Not 5 because of these minor coverage gaps; not 3 because multiple concrete actions are explicitly named.

Completeness

The 'what' is clear (make a clean PR in mflux via the listed steps), but there is no 'Use when...' clause or equivalent explicit trigger guidance in the description — the 'when' lives only in the body's 'When to Use' section. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3.

Trigger Term Quality

Natural terms users would say — 'PR', 'commit', 'push', 'diff', 'repo' — are present, but common variations like the spelled-out 'pull request' or 'open a pull request' are missing. Not 5 because synonym coverage is incomplete; not 3 because keyword coverage is good rather than partial.

Distinctiveness Conflict Risk

'Make a clean PR in mflux' carves out a clear repo-scoped niche, but closely related sibling skills (e.g. 'mflux-pr-docs' for PR bodies) and generic PR-creation behavior create minor overlap risk. Not 5 due to that overlap with closely related skills; not 3 because the mflux scoping and concrete step list make it mostly distinct.
