Conciseness

The body is dense and imperative with zero concept-explanation padding, but the sync-debt paragraph ("inspect every completed task's Context synchronization field in the plan, in plan order...") duplicates plan-review.md nearly verbatim, the "do not restate/summarize/reconstruct" guard repeats four-plus times, and the Rules section restates constraints already stated inline. This is more than minor trimming, matching the mostly-efficient-but-could-be-tightened anchor.

Actionability

Fully executable instruction guidance: exact $ARGUMENTS parsing grammar with token-matching rules and explicit error behavior ("A token matching neither a task ID nor approved is an error... and stop"), exhaustive status-branch tables, named render targets, concrete command templates like "/next-task {candidate-path}", and exact lifecycle-write fields. As an instruction-only skill whose guidance is maximally concrete, the absence of code is not penalized.

Workflow Clarity

A clear four-step sequence with explicit gates, per-status branch handling, defined stop conditions for every outcome, and error-recovery feedback loops ("If that lifecycle write fails, treat the outcome as blocked"; "Preserve completed work and evidence when a later phase fails"), plus a Rules checklist. Validation is built into each phase (task execution verifies, sync verifies root context files), so the missing-validation cap does not apply.

Progressive Disclosure

The overview holds only control flow and dispatches phase detail to one-level-deep references via a clear step-to-file table with explicit read-before rules; all referenced files (plan-review.md, task-execution.md, context-sync.md, output.md) exist. Not 5 because the sync-debt rules are inlined in the body despite living in plan-review.md, and sync-report.md is reachable only via a second hop through context-sync.md; not 3 because references are clearly signaled and the split is otherwise appropriate.

Specificity

"Review, approve, implement, verify, and synchronize one SCE plan task" lists five concrete action verbs with a bounded object, matching the several-specific-actions anchor. Not 5 because it gives no coverage of what each action entails (what is reviewed, what is synchronized); not 3 because more than 1-2 concrete actions are named.

Completeness

A clear "what" is present (five named actions on an SCE plan task) but there is no "when" clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. This exactly matches the anchor-3 pattern of an action list without a use-when clause.

Trigger Term Quality

Relevant domain keywords are present ("plan", "task", "approve", "review") but the natural phrase a user would say for this skill — "next task" — is entirely absent, along with any synonyms or invocation context. Not 4 because core natural trigger terms are missing, not 2 because several relevant keywords exist beyond one or two generic ones.

Distinctiveness Conflict Risk

"one SCE plan task" carves a clear niche and scopes execution to a single task, keeping it mostly distinct. Not 5 because of overlap risk with closely related sibling SCE skills (e.g. sce-decision) and the absence of trigger guidance to disambiguate invocation; not 3 because the SCE-plan-task domain is far more specific than generic file or document skills.
