Conciseness

The body is lean and sectioned with no explanations of concepts Claude already knows (it never explains what Biome or linting is). Anchor 4 rather than 5 because of minor trim opportunities: the "Avoid" and "Anti-Patterns" sections overlap substantially, and the bare-noun Inputs/Outputs lists plus "Philosophy" platitudes ("Keep the workflow evidence-first and bounded to the requested scope") earn their place only loosely.

Actionability

No concrete command appears anywhere — no `biome check`, no `biome check --fix --safe`, no named config file, and "Inspect 2-3 focused surfaces" never says which surfaces. This matches anchor 2 ("Minimal concrete guidance; high-level hints but missing the specific steps to execute") rather than anchor 1, because the Workflow and Validation sections do instruct sequencing and fail-fast behavior rather than merely describing.

Workflow Clarity

The Workflow section gives a clear five-step sequence with explicit validation checkpoints ("Stop at the first failed gate or blocker", "Rerun the relevant validation after fixes before claiming completion") and a fix-then-rerun feedback loop, echoed by the Validation section — so the destructive/batch cap at 3 does not apply. Anchor 4 rather than 5 because the steps are abstract ("Take the smallest action that advances the confirmed goal") without the concrete commands the anchor-5 example includes.

Progressive Disclosure

Sections are well organized and the body is short, but scored against the actual bundle: the only reference pointer ("Archived source, scripts, assets, and long-form references live under `Infrastructure/references/deferred-skill-context/agent-ops-biome-linting/`") does not resolve to any file in the bundle, while the real bundle files (`references/contract.yaml`, `references/evals.yaml`, `references/task-profile.json`) are never mentioned. This fits anchor 3 ("references present but not clearly signaled" / organization gaps) better than anchor 4, since the sole pointer is dangling relative to the actual file listing.

Specificity

The description lists several concrete actions ("Analyze, fix, and validate") tied to a named domain, with objects like "Biome commands, diagnostics, safe fixes, or CI lint gates". It sits at anchor 4 rather than 5 because coverage within the Biome niche has minor gaps — no mention of formatting, config setup, or rule tuning, which are core parts of Biome usage.

Completeness

It explicitly answers both parts: the "what" ("Analyze, fix, and validate Biome linting workflows") and the "when" via a concrete "Use when JavaScript or TypeScript projects need Biome commands, diagnostics, safe fixes, or CI lint gates" trigger clause. This matches the anchor-5 pattern of a clear what plus an explicit when with concrete trigger phrases.

Trigger Term Quality

Good natural keyword coverage: "Biome" (repeated), "lint", "diagnostics", "CI lint gates", "safe fixes", "JavaScript or TypeScript projects" — terms a user with a Biome problem would plausibly say. Not anchor 5 because common variations like "linter", "lint errors", or "formatting" are missing, so a few natural terms users might say are absent.

Distinctiveness Conflict Risk

"Biome" is a specific named tool, making this a clear niche with distinct triggers; the description is unlikely to capture generic linting or ESLint requests because every capability is scoped to Biome. Anti-drift check against anchor 4 ("minor overlap risk with closely related skills") finds no meaningful overlap, since the tool name gates every trigger.
