86%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.
A highly actionable, token-efficient SDK reference with executable code throughout and a well-sequenced integration workflow. Its main weakness is structure: it is a monolithic single-file reference with no progressive disclosure to separate reference files.
Suggestions
Move the larger capability areas (Advertisement, Payments/IAP, Leaderboards) into separate files under references/ and link to them from SKILL.md so the main file stays a concise overview with one-level-deep references.
Add an explicit validation checkpoint for storage writes — e.g., re-read with getData() after setData() to confirm the merge persisted — since each call overwrites the full document.
Add a verification step in the consume-purchase flow (re-call getPurchases() to confirm the token is gone after consumePurchase) to close the validation gap on that destructive operation.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean reference-style content: tight executable snippets with prose reserved for SDK-specific gotchas ('Treat wasShown === false as a failure', 'Grant the reward inside onRewarded', 'Every call writes the full document'), avoiding any explanation of concepts Claude already knows. | 5 / 5 |
Actionability | Nearly every section provides fully executable, copy-paste-ready JavaScript functions (getPlayer, showInterstitial, purchase, setLeaderboardScore, etc.) that cover the common integration cases with real SDK method calls. | 5 / 5 |
Workflow Clarity | The Quick Start bootstrap is sequenced as numbered steps 1–7 with 'Verify each step before proceeding to the next', a try/catch fallback for player init, and a purchaseToken check; minor gaps remain, notably no formal validate-retry loop for the full-document storage overwrite. | 4 / 5 |
Progressive Disclosure | The skill is well-organized with clear section headers and an overview map, but at ~390 lines everything is inlined into SKILL.md with no references/ bundle files; distinct capability areas (ads, IAP, leaderboards) that could be split into one-level-deep references are kept inline. | 3 / 5 |
