Conciseness

Every section earns its tokens: a five-row options table, a compact channel list, a one-line legend, three numbered steps, and two targeted mistakes. Nothing explains concepts Claude already knows and there is no padding, matching anchor 5 (lean and efficient; every token earns its place).

Actionability

The core command `yarn flags $ARGUMENTS` is copy-paste ready and the option syntax (`--diff <ch1> <ch2>`, `--cleanup`, `--csv`), channel names, and legend are concrete. It falls short of anchor 5 only because there are no worked example invocations (e.g., `yarn flags --diff www next`) and 'highlight meaningful differences' leaves what counts as 'meaningful' implicit — minor gaps typical of anchor 4.

Workflow Clarity

This is a simple, single-purpose skill under 50 lines whose single action is unambiguous: 'Run `yarn flags $ARGUMENTS`', then explain, with a --diff-specific follow-up — the rubric's simple-skill exception allows a 5. The read-only reporting command involves no destructive or batch operations, so no validation cap applies, and 'Common Mistakes' supplies the guidance a checklist would.

Progressive Disclosure

The skill is under 50 lines with no need for external references (no references/, scripts/, or assets/ exist, and the body references none), and its sections — Options, Channels, Legend, Instructions, Common Mistakes — are well-organized, which per the rubric's simple-skill note earns anchor 5. Nothing that belongs in a separate file is inlined.

Specificity

The description lists three concrete actions — "check feature flag states", "compare channels", "debug why a feature behaves differently across release channels" — which would otherwise land at 4, but it omits capabilities the body documents (listing all flags, cleanup status, CSV output) and uses second-person voice ("Use when you need to"), which the judging guidelines penalize by 1. The result is anchor 3: names the domain and 1-2 effective concrete actions without comprehensive coverage.

Completeness

Both what ("check feature flag states, compare channels, or debug...") and when ("Use when you need to...") are present in a single clause, so both questions are answered but not as two explicit, maximally concrete statements — matching anchor 4 rather than anchor 5. It is above anchor 3 because the when-clause is explicit, not merely implied.

Trigger Term Quality

Natural phrases like "feature flag states", "compare channels", "release channels", and "debug why a feature behaves differently" map well onto what a user would say. It misses common synonyms and variations (e.g., "flag", "toggle", "gate", specific channel names like canary/next), so it fits anchor 4 (good keyword coverage, a few natural terms missing) rather than anchor 5.

Distinctiveness Conflict Risk

The feature-flag/release-channel niche is distinct with trigger phrasing ("feature flag states", "release channels") unlikely to fire for unrelated skills — matching anchor 5's clear niche with distinct triggers and minimal conflict risk. Anchor 4's 'minor overlap risk with closely related skills' would apply only if a generic debugging or release-management skill existed with overlapping triggers, which the wording here avoids.
