arn-code-execute-task
This skill should be used when the user says "execute task N", "run task N", "implement task N", "re-run task N", "retry task N", "run single task", or wants to execute a single specific task from the task list with optional review. This is for ONE task only — for executing the full plan (all tasks), use arn-code-execute-plan instead.

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description excels at trigger term coverage and completeness, with explicit trigger phrases and clear differentiation from the related full-plan execution skill. Its main weakness is that the actual capabilities (what 'executing a task' involves concretely) are somewhat underspecified — it tells you when to use it very well but is lighter on the specific actions performed. The description also uses second person ('the user') in a contextually appropriate way for trigger guidance rather than capability description.
Suggestions
Add 1-2 sentences describing the concrete actions performed when executing a task (e.g., 'Reads task specifications from the task list, implements the required code changes, runs tests, and optionally pauses for review before marking complete').
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain (executing a single task from a task list) and mentions 'optional review', but doesn't describe concrete actions beyond 'execute/run/implement a task'. It lacks specifics about what executing a task entails (e.g., reading task details, running code, updating status). | 2 / 3 |
Completeness | Clearly answers both 'what' (execute a single specific task from the task list with optional review) and 'when' (explicit trigger phrases listed, plus differentiation from the full plan execution skill). The 'Use when' equivalent is the opening clause. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger phrases: 'execute task N', 'run task N', 'implement task N', 're-run task N', 'retry task N', 'run single task'. These are highly specific phrases a user would naturally say, and the variations cover common synonyms. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — explicitly differentiates itself from 'arn-code-execute-plan' for full plan execution, and the trigger terms are very specific ('execute task N' pattern). The 'ONE task only' emphasis and the contrast with the sibling skill make conflict unlikely. | 3 / 3 |

Implementation
70%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill excels at actionability and workflow clarity — every step is concrete, well-sequenced, and includes proper validation/escalation paths. However, it suffers from being a monolithic document (~200 lines) that tries to contain everything inline, including detailed progress tracker JSON update logic, comprehensive error handling branches with exact user prompts, and repeated visual testing configuration notes. Extracting detailed sub-procedures into referenced files would significantly improve token efficiency and progressive disclosure.
Suggestions
Extract the PROGRESS_TRACKER.json update logic (Step 5.4) into a separate reference file, since it contains detailed JSON field manipulation that could be shared across skills.
Move the detailed error handling section (especially the test failure branches with their multi-option prompts and issue creation logic) into a separate ERROR_HANDLING.md reference file.
Consolidate the visual testing configuration mentions — it's referenced in Steps 4, 5, and 6 with repeated caveats about Layer 1 vs multi-layer. A single reference to a visual testing config doc would reduce redundancy.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is quite lengthy (~200 lines) with some redundancy (e.g., visual testing config is mentioned multiple times across steps, the PROGRESS_TRACKER.json update logic is very detailed). However, most content is task-specific configuration that Claude wouldn't inherently know, so it's not explaining basic concepts. It could be tightened by extracting the progress tracker update logic and error handling branches into separate files. | 2 / 3 |
Actionability | The skill provides highly specific, concrete guidance: exact file paths to check, specific tool parameters (Task tool with resume parameter, AskUserQuestion), exact JSON fields to update (completedAt, overallStatus, review.verdict), specific user-facing messages to display, and precise branching logic for test failure scenarios. The directory structure is shown explicitly. | 3 / 3 |
Workflow Clarity | The 6-step workflow is clearly sequenced with explicit validation checkpoints: verify task exists (Step 2), verify project directory (Step 4.2), handle review verdicts with feedback loops (Step 5.3 with max 2 cycles then escalate), and progress tracker updates. Error handling is comprehensive with specific branches for different failure modes including resume fallback. | 3 / 3 |
Progressive Disclosure | This is a monolithic wall of text with no bundle files to offload detailed content. The progress tracker update logic (Step 5.4), the detailed error handling branches (especially the test failure branches with their multi-option user prompts), and the visual testing configuration details could all be extracted into separate reference files. Everything is inline in one large document. | 1 / 3 |
