82%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is highly actionable and well-structured: executable commands with expected results, a complete canonical room example, four WHY/BAD/GOOD anti-patterns, a checkpointed workflow, and verified one-level-deep references. The main costs are duplicated code between the example and anti-patterns, two skill-maintenance commands that don't serve the task, and inline bulk that could partially move to references.
Suggestions
De-duplicate the reconnection and move-validation code: the anti-patterns repeat the 'onLeave' and 'move' handler blocks verbatim from the main example — reference the example and show only the delta.
Remove or relocate the meta commands ('Evaluate this skill quality', 'Lint this skill docs') out of the task-facing Quick Commands section; they consume tokens without helping implement a Colyseus server.
Add fix-and-retry guidance to the two workflow checkpoints (e.g., 'if plain properties are found, migrate them to Schema fields and re-verify') to upgrade validation steps into feedback loops.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and assumes Claude's competence — no space is spent explaining what websockets or Colyseus are — but the 'onLeave' reconnection code is duplicated verbatim between the main example and its anti-pattern, the 'move' validation appears twice, and two meta commands ('Evaluate this skill quality', 'Lint this skill docs') serve skill maintenance rather than the task. This puts it above anchor 3 (only minor trimming needed) but below anchor 5's every-token-earns-its-place standard. | 4 / 5 |
Actionability | Scaffold and run commands are copy-paste ready with expected results ('npm create colyseus-app@latest server', 'bun run src/index.ts'), and the TypeScript room example is complete and executable with imports, Schema definitions, handlers, and server-side clamping. Anti-patterns pair BAD/GOOD code for each rule, matching anchor 5's fully-executable, common-cases-covered standard. | 5 / 5 |
Workflow Clarity | The 8-step 'Deterministic Workflow' is clearly sequenced with two explicit checkpoints ('Verify schema sync with a test client', 'Simulate a transient disconnect and confirm allowReconnection restores session'). It falls short of anchor 5 because the checkpoints state what to verify but give no fix-and-retry recovery guidance if verification fails. | 4 / 5 |
Progressive Disclosure | Three real, one-level-deep reference files (room-lifecycle-and-state.md, message-validation-and-security.md, matchmaking-and-reconnection.md) are clearly signaled with one-line descriptions, matching good structure. It stops short of anchor 5 because roughly 150 lines of inline example and anti-pattern code sit in SKILL.md where some could be split into the references to keep the overview lean. | 4 / 5 |
