The content is mostly efficient and avoids explaining concepts Claude already knows, but there's some redundancy between the 'Mandatory implementation stop' section and step 1-3 of the 'Required sequence' which restate the same information. The examples are valuable but the surrounding prose could be tighter.

The skill provides concrete, specific guidance with a fully fleshed-out example of the mandatory stop prompt and a concrete example of the task status update format. The required sequence is explicit with specific file paths and tool actions (tests, lints, build). Claude knows exactly what to do at each step.

The 8-step required sequence is clearly ordered with an explicit approval gate (step 3) before any implementation, validation via tests/lints/build (step 5), and a scope expansion rule that acts as a feedback loop for out-of-scope changes. The mandatory stop before destructive operations (code changes) is well-defined with clear criteria.

For a standalone skill with no bundle files, the content is well-organized into clearly labeled sections (Scope rule, Mandatory implementation stop, Required sequence, Scope expansion rule) with appropriate use of examples inline. The skill is under 80 lines and doesn't need external references; the structure is clean and navigable.

Lists multiple specific concrete actions: 'coding a feature, applying a patch, making targeted file changes' along with specific mechanisms like 'approval gate, scope guardrails, evidence capture, pre-implementation confirmation prompt, test/lint verification, status tracking'.

Clearly answers both what ('executes a single planned implementation task with approval gate, scope guardrails, and evidence capture') and when ('Use when a user wants to implement, run, or execute a specific task from a project plan') with explicit trigger guidance and concrete examples.

Includes strong natural trigger terms users would say: 'implement', 'run', 'execute', 'task', 'project plan', 'coding a feature', 'applying a patch', 'file changes'. These cover common variations of how users would request task execution.

Highly distinctive with its specific niche: executing tasks from a project plan with mandatory approval gates, scope boundaries, and status tracking in a specific file path (context/plans/{plan_id}.md). Unlikely to conflict with general coding or file editing skills due to the structured workflow emphasis.
