Conciseness

The body is dense operational instruction with essentially no explanation of concepts Claude already knows — every section prescribes checks, exact paths, or decision branches. Minor trimming is available (the AskUserQuestion prose blocks are verbose, and task-recreation guidance repeats across Step 2 and Error Handling), which keeps it at anchor 4 rather than 5, but it is well above anchor 3's 'some unnecessary explanation'.

Actionability

Guidance is concrete throughout: exact directory structure to verify, exact user-facing questions with numbered options, specific commands ('gh issue create'), and explicit fallback branches for executor/reviewer failures and resume errors. It falls short of anchor 5 mainly because some steps defer to material not directly resolvable from this skill — e.g. 'run the template version check procedure documented in arn-code-save-plan Step 1' — leaving the orchestrator to chase a cross-skill document.

Workflow Clarity

Steps 1–5 are explicitly sequenced with validation checkpoints at every phase: structure verification before execution, user confirmation before starting the batch, and an execute→review→gate cycle with a retry cap (2), escalation to the user, and abort options. This batch operation has textbook feedback loops and error-recovery paths, matching anchor 5 exactly.

Progressive Disclosure

The SKILL.md is a genuine overview: the 12KB dispatch algorithm and pattern-refresh procedure are split into well-signaled, real, one-level-deep reference files ('Read ${CLAUDE_PLUGIN_ROOT}/skills/arn-code-execute-plan/references/dispatch-loop.md'). It falls short of anchor 5 because navigation depends partly on cross-skill pointers the reader must hunt down — dispatch-loop.md repeatedly points into arn-code-ensure-config/references/ensure-config.md, and Step 1 defers to a named step inside arn-code-save-plan — which weakens 'easy navigation'.

Specificity

The description names the domain (structured project plan execution) and one concrete action — 'This skill runs ALL tasks from the task list' — but does not enumerate the skill's actual capabilities (parallel executor dispatch, reviewer validation, retry/escalation gates). It fits anchor 3 (domain plus 1-2 concrete actions, not comprehensive); it is not a 4 because there is no list of several specific actions, and not a 2 because the action stated is concrete and the routing behavior is explicit.

Completeness

Both 'what' ('This skill runs ALL tasks from the task list') and 'when' (explicit trigger phrases) are present, but the 'what' is thin — it never says what the skill does beyond running tasks (no mention of dispatching parallel executors, review gates, or escalation). It is above anchor 3 (both present, 'when' explicit with concrete trigger phrases) but short of anchor 5, which requires the 'what' to be equally explicit and concrete.

Trigger Term Quality

It quotes seven natural trigger phrases users would actually say — "execute plan", "run the plan", "execute project", "execute all tasks", "run all tasks", "run plan in parallel", "execute with review gates" — plus a general intent clause ('wants to execute a full structured project plan'). This is comprehensive coverage of natural terms and synonyms, matching the anchor 5 example.

Distinctiveness Conflict Risk

It occupies a clear niche with an explicit negative trigger ('Do NOT use this skill when executing a single task — use `/arn-code-execute-task` instead') and positive routing to sibling skills (arn-code-execute-task, arn-code-execute-plan-teams, arn-code-taskify). The trigger phrases are distinctive to full-plan execution, so mis-trigger risk is minimal — a clear anchor 5.
