Conciseness

The body is lean and imperative with essentially no padding — "Task vars are template inputs, not environment exports to cmds" assumes competence and earns every token. Not 5 because the opening blockquote carries time-sensitive version/date information ("Based on Task 3.54.0 documentation retrieved on 2026-10-21") outside any versioning or compatibility section, which the rubric directs to penalize.

Actionability

Concrete keys and flags are named throughout ("deps", "task:" entries in "cmds", "status", "preconditions", "--dry", "--force", "--yes", "task --version"), but several of the most concrete instructions point to files missing from the bundle: "use the [ordered-calls Taskfile](examples/ordered-calls/Taskfile.yml)" and "check uncommon keys against the [bundled schema](docs/contents/reference/schema.md)" are dead references, and no inline Taskfile snippet compensates. This is missing key details rather than the minor gaps of the 4 anchor.

Workflow Clarity

The five-step workflow is clearly sequenced from "Identify the effective configuration" through "Verify the changed behavior", with explicit validation ("exercise a disposable fixture: successful execution, relevant failure, and actual outputs" including caching edge cases) and feedback loops ("expected versus observed outputs/failures", symptom-driven "correction, and recovery check"). The "Essential contracts" section functions as a checklist, and the closing explicitly rejects dry-run transcripts as evidence.

Progressive Disclosure

The in-body structure is good — a well-signaled one-level-deep <references> block where all six listed references/*.md files exist with verified anchors — but five referenced paths are absent from the actual bundle (docs/index.md, docs/contents/reference/schema.md, examples/README.md, examples/ordered-calls/Taskfile.yml, GENERATION.md), breaking navigation to the claimed "complete offline documentation" and "example catalog". Missing referenced files are a structural gap beyond the minor organization issues of the 4 anchor.

Specificity

"Authors, reviews, and diagnoses Task (go-task) automation in Taskfile.yml, Taskfile.yaml, included Taskfiles, and .taskrc.yml" lists multiple concrete actions against specific named artifacts, and the when-clause enumerates seven concrete scenarios (typed inputs, stale builds, watch/CI failures, remote Taskfile trust) covering the tool's surface. Not 4 because coverage extends beyond a few actions into the domain's distinct sub-areas without abstraction or padding.

Completeness

The what-clause ("Authors, reviews, and diagnoses Task (go-task) automation in Taskfile.yml...") and an explicit "Use for ordered or parallel workflows, typed inputs and CLI arguments, stale builds..." when-clause both appear with concrete trigger phrases. Both questions are answered explicitly, matching the top anchor.

Trigger Term Quality

Includes the natural terms users of this tool actually say — "Taskfile.yml", "Taskfile.yaml", ".taskrc.yml", "go-task", "stale builds", "monorepo tasks", "typed inputs and CLI arguments" — with both synonyms and file extensions present. This matches the comprehensive-coverage anchor rather than the good-coverage anchor, which would require missing natural variations.

Distinctiveness Conflict Risk

"Task (go-task)" plus the Taskfile file names establish a clear niche with distinctive triggers, but generic phrases like "ordered or parallel workflows", "stale builds", and "watch/CI failures" carry minor overlap risk with closely related build/CI skills (Make, GitHub Actions). Not 5 because those unscoped generic terms could plausibly trigger the skill for non-Task problems; not 3 because the tool-specific file names dominate the description's identity.
