78%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 a well-structured, highly actionable skill: a gated workflow with explicit checkpoints, runnable quick commands with expected results, concrete BAD/GOOD anti-pattern code, and a clean reference split across three real bundle files. The deductions are minor — a duplicated principles section, overlapping anti-patterns, and a non-compiling `y` field in the main example's Schema — none of which undermine the guidance.
Suggestions
Add the missing `y` field (e.g. `@type("number") y: number = 0;`) to the `Player` Schema in the room implementation example so the `move` handler compiles as written.
Merge the "Philosophy" and "Core Principles" sections, which restate the same four rules, and consolidate the overlapping anti-patterns on trusting client position/score and absolute coordinates into one entry.
Add a failure branch to each workflow checkpoint (e.g. "if propagation fails, check for plain properties and re-run the test client") to close the workflow-clarity gap.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and assumes Claude's competence — no basic-concept explanations — but there is tightening available: the "Philosophy" bullets and "Core Principles" list restate the same four rules ("Server is authoritative for all game state" vs "the server decides, the client only asks"), and anti-patterns "NEVER trust client position or score updates directly", "NEVER skip payload validation", and "NEVER accept absolute client coordinates" overlap substantially. This sits between anchor 4 (minor instances that could be trimmed) and anchor 3; the duplication is real but localized, so 4 fits better than 3. | 4 / 5 |
Actionability | Guidance is mostly copy-paste ready: runnable commands ("npm create colyseus-app@latest server", "bun run src/index.ts") with expected results, a full room implementation, and BAD/GOOD code pairs. However, the main example's `move` handler executes `player.y += dy` while the `Player` Schema declares only `sessionId`, `x`, and `score` — the code does not compile as written, a minor gap that keeps it below anchor 5 ("copy-paste ready code ... cover the common cases") but comfortably above anchor 3 (pseudocode/incomplete). | 4 / 5 |
Workflow Clarity | The "Deterministic Workflow" gives a clear 8-step sequence with two explicit bolded checkpoints ("**Checkpoint:** Verify schema sync with a test client before proceeding — confirm field changes propagate and no plain properties are used") plus a final multi-client verification step, so validation is present and gating ("before proceeding"). It falls short of anchor 5 only because there are no failure branches (what to do when a checkpoint fails) — matching anchor 4 ("clear sequence with most checkpoints present; minor validation gaps") rather than 3, since checkpoints are explicit, not merely implicit. | 4 / 5 |
Progressive Disclosure | The body is a clear overview with a navigation table of three one-level-deep references, each with a topic and a "When to Use" column, and all three linked files exist in ./references/ with content matching their stated scope. Detail (lifecycle ordering, timeout policies, handler skeletons) is appropriately split out of SKILL.md, matching anchor 5 ("Clear overview with well-signaled one-level-deep references; content appropriately split"). | 5 / 5 |
