Conciseness

Nearly every line carries operational specifics — exact commands, ports, env-var names — with no explanation of concepts Claude already knows, placing it above anchor 3. It sits at anchor 4 rather than 5 because of trimmable narrative: the historical-incident anecdotes ('that is what happened on the 2026-08-07 shakedown') and the WebTransport UDP-port mechanics paragraph could be tightened or pushed to references.

Actionability

Fully executable throughout: 'git status --porcelain # must be clean', './mvnw install -DskipTests -Pfastinstall', 'grep 'AI config:' target/sweep/<sample>-<port>.log', the complete 'sweep-sample.sh start <sample> --port <9101+n> --ready-path <path> --env LLM_MODE=local' invocation, exact model names ('qwen2.5:3b', 'qwen2.5:7b-instruct-q4_K_M'), and a copy-paste attestation JSON template. This matches the 5 anchor — copy-paste-ready commands covering the common cases.

Workflow Clarity

Steps 0–5 are explicitly sequenced with validation checkpoints at every risky point (clean-tree check, launcher that 'refuses to boot if the port is already answering', teardown that 'verifies the port is actually released', PASS/PARTIAL/FAIL evidence rules) plus an explicit feedback loop — 'Repeat triage → fix → re-test until the sweep is clean'. For a 33-sample batch operation this matches the 5 anchor with validation, error recovery, and checklists all present.

Progressive Disclosure

Verified against the actual bundle: all seven references/, the script, and the asset exist with real content, and each is cited at the exact point of use (references/expo-sweep.md at Step 1b, references/cli-sweep.md at Step 1c, references/regression-specs.md at Step 3). References are one level deep with no nested pointers, and the 'Files in this skill' table aids discovery — matching the 5 anchor. Not a 4: there is no content that clearly belongs in a separate file still inlined; the body keeps only the orchestration procedure.

Specificity

Enumerates multiple concrete actions with comprehensive coverage — 'booted from their packaged artifacts and driven in a real browser via chrome-devtools MCP', 'the per-sample launch/drive/collect/teardown loop', 'the evidence ledger, the fix phase (every issue gets a biting regression test in the right suite), the re-test subset, and the report'. Every phrase names a distinct capability with no padding, matching the 5 anchor; it exceeds 4 because the phase list is complete rather than having minor gaps.

Completeness

Explicitly answers both: what — 'Run the pre-release end-to-end sweep of every user-facing surface — the 33 samples... the Expo/React Native client, and the atmosphere CLI'; when — 'Use before cutting a release, and after any change to the Console bundle, a shared module, atmosphere.js, the CLI, or several samples at once'. Concrete trigger phrases match the 5 anchor exactly; a 4 would require the 'when' to be less explicit than this.

Trigger Term Quality

Good natural-keyword coverage: 'release', 'sweep', 'samples', 'chrome-devtools', 'Console', 'CLI', 'Expo client' — phrases a maintainer would actually say. It falls short of the 5 anchor ('comprehensive coverage including synonyms and file extensions') because variations like 'E2E', 'smoke test', or 'pre-release check' are absent.

Distinctiveness Conflict Risk

A clear niche with distinct triggers — repo-specific surfaces ('33 samples under samples/', 'the atmosphere CLI', 'chrome-devtools MCP') make it unmistakable and virtually impossible to trigger for the wrong skill. It is not a 4 because there is no realistic overlap with even closely related skills.
