y8-js-sdk

Integrates the Y8 JavaScript SDK into JavaScript and HTML5 games. Covers SDK loading and initialization handshake, player authentication via Y8 login, cloud-backed user data storage, interstitial and rewarded ads through Google AdSense, native achievement unlocking and listing, and in-game leaderboard score submission and retrieval. Use when the user mentions Y8 SDK, Y8 API, Y8 integration, Y8 leaderboard, Y8 achievements, Y8 login, or adding Y8 features to a JavaScript or HTML5 game.

Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A high-quality, code-dense skill body with executable functions across every SDK area and a checkpoint-driven integration workflow. It is lean and actionable, with only minor room to split some reference material into bundled files.

Suggestions

Move the full Advertisement or Leaderboards code reference into a bundled reference file (e.g. references/ads.md) and link to it from SKILL.md to improve progressive disclosure for this longer skill.

Tighten the Integration Workflow overview so it reads as a pure checklist rather than restating details already covered in the sections below.

Add an explicit error-recovery feedback loop (validate → fix → retry) for the storage save path, since cloud writes can fail silently.

DimensionReasoningScore

Conciseness

Prose is lean and assumes Claude's competence (no explanations of what an SDK or ads are), but the 'Integration Workflow' overview restates steps that are then fully elaborated in the sections below — a minor trim opportunity rather than padding.

4 / 5

Actionability

Provides fully executable, copy-paste-ready functions covering every common case — loadScript/waitFor, initY8, readPlayerInfo/authorizePlayer, storage CRUD, showInterstitial/showRewarded, achievement unlock/list/popup, and leaderboard submit/fetch.

5 / 5

Workflow Clarity

The 'Integration Workflow' section sequences six numbered steps each with an explicit '✓ Verify' checkpoint, and includes light error-recovery guidance ('if it never fires, check the appId'), matching the anchor for a clear sequence with explicit validation steps.

5 / 5

Progressive Disclosure

Well-organized into clearly headed sections with no broken or nested references, but the ~440-line body keeps all bulk reference code inline in a single file rather than splitting detailed API examples into separate reference files.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that concretely enumerates the SDK's capabilities and pairs them with an explicit, natural-language trigger clause. It is specific, complete, and highly distinguishable from other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'SDK loading and initialization handshake', 'player authentication via Y8 login', 'cloud-backed user data storage', 'interstitial and rewarded ads', 'achievement unlocking and listing', 'leaderboard score submission and retrieval' — giving comprehensive coverage rather than vague language.

5 / 5

Completeness

It explicitly answers both 'what' (detailed capability list) and 'when' (a concrete 'Use when the user mentions...' clause with trigger phrases), matching the anchor for clearly and explicitly answering both.

5 / 5

Trigger Term Quality

The 'Use when the user mentions Y8 SDK, Y8 API, Y8 integration, Y8 leaderboard, Y8 achievements, Y8 login, or adding Y8 features' clause covers the natural phrases a user would say, including synonyms and the platform-specific variations.

5 / 5

Distinctiveness Conflict Risk

Y8 is a specific platform and every trigger is Y8-qualified, giving a clear niche with distinct triggers and minimal overlap risk with unrelated skills.
