Conciseness

The ~40-line body is lean with no padding or explanations of concepts Claude already knows ('Give leaf commands explicit inputs and effects', 'sh can execute during --dry'). The inline version pin 'Existing Task examples target 3.54.0' is time-sensitive information not placed in a deprecated/old-patterns section, which the guidelines penalize, keeping this just below anchor 5.

Actionability

Guidance is mostly executable with concrete commands and flags ('Inspect existing changes and task --version', 'check pi --version', 'sh can execute during --dry', 'Use includes for reuse, cmds task calls for order'). Per the instruction-skill scoring note the absence of full code examples inline is acceptable, but some directives remain at policy level ('Give leaf commands explicit inputs and effects') without a concrete illustration, so anchor 4 fits better than 5.

Workflow Clarity

The five-step sequence (locate consumer → read contract → compose smallest change → exercise boundary → close with evidence) is clear, with explicit completion criteria ('Done when the changed behavior has an owner...') and a genuine validation step ('choose a disposable check that could expose the feared failure'). It falls short of anchor 5 because there is no explicit fix-and-retry feedback loop after a failed check, and the dense phrasing slightly obscures some checkpoints.

Progressive Disclosure

Structure is good: a compact overview, a routing rule ('Read only the branches needed for the current decision; follow another when the boundary changes'), and 12 well-signaled one-level-deep references with per-link descriptions. However, three of the referenced paths — examples/README.md, examples/ordered.yml, and GENERATION.md — do not exist in the bundle, so navigation breaks exactly where the body points for the smallest starting point ('[ordered calls](examples/ordered.yml) is the smallest starting point').

Specificity

Lists several specific actions tied to named artifacts ('Create, update, run, publish, and troubleshoot Go Task Taskfiles and Slurpyb pi-taskfile workflows, agent configurations, and helper extensions'). The verbs are somewhat generic lifecycle terms compared to anchor 5's artifact-level actions, and concrete behavior per area (e.g., what 'update' involves) is left to the when-clause, so anchor 4 is the best fit.

Completeness

Clearly answers both parts: the what is the explicit lifecycle ('Create, update, run, publish, and troubleshoot...'), and the when is an explicit 'Use for' clause with concrete triggers ('native task composition, variables and includes, build freshness, Pi invocation and Markdown inputs, package distribution, or execution failures'). This matches anchor 5 directly; anchor 4 would require a vaguer when-clause.

Trigger Term Quality

Good keyword coverage with the natural product names users would say: 'Go Task', 'Taskfiles', 'pi-taskfile', 'variables and includes', 'build freshness', 'package distribution', 'execution failures'. A few natural terms are missing — 'task runner', 'Taskfile.yml', and generic build-tool phrasing — so it sits between anchors 4 and 5, closer to 4.

Distinctiveness Conflict Risk

Mostly distinct: 'Go Task Taskfiles' and 'Slurpyb pi-taskfile' name a clear niche with minimal overlap against unrelated skills. Minor conflict risk remains because the generic word 'task' and the trigger 'execution failures' could plausibly match task-list/todo or generic failure-triage skills, fitting anchor 4 rather than 5.
