Conciseness

Mostly dense, high-value domain guidance, but there is real redundancy: the 'When to use this skill' section (lines 64–78) restates the Activation Contract's 'Use this first when' / 'Do NOT use for' scope almost verbatim, and the wechatide-missing policy is stated three times (Activation Contract gotchas, 'How to use this skill' step 5, and 'Debugging, Preview, and Publishing'). This fits the score-3 anchor ('mostly efficient... could be tightened') rather than score 2, since none of it is generic explanation of concepts Claude already knows — nearly every line carries skill-specific rules.

Actionability

Concrete, executable material is present: a copy-paste `app.json` custom-tabBar config with a flex-centering recipe, a full minimal project skeleton (app.js/wxml/json + `project.config.json`), exact flags ('-c <clientName>', '--remote-npm-install'), and the precise API 'cloud.openapi.customerServiceMessage.send'. It falls short of the score-5 anchor because the highest-frequency executable actions — actual `wechatide` command invocations and `miniprogram-ci` calls — are deferred to reference files rather than shown inline, leaving the body's most common cases as routing instructions rather than copy-paste commands.

Workflow Clarity

The 'How to use this skill' section lays out a clear 5-step sequence with per-scenario routing, and the publish path has an explicit decision branch with a checkpoint (wechatide missing → report, offer install, wait for user; only after decline → fallback and enumerate lost capabilities), plus mandatory Change Safety Protocol and Deployment Gate gates before code changes and uploads. It sits at score 4 rather than 5 because the validation content of those gates lives entirely in referenced protocol files — the body never states what the gate checks are — so checkpoints are enforced by pointer rather than by explicit inline steps.

Progressive Disclosure

The body is a true overview: six reference files exist in the bundle, every one is linked with a clear 'read X when <scenario>' signal, and detail is split appropriately (SEO, message push, DevTools debugging, pitfalls, CloudBase integration each live in their own file). Reference files cross-link only to same-level peers as 'see also' navigation, not as buried content chains, so references are effectively one level deep — matching the score-5 anchor of a clear overview with well-signaled one-level-deep references and easy navigation.

Specificity

The description enumerates many concrete capabilities — 'building, debugging, previewing, testing, publishing, and optimizing' — and grounds them in specifics like '`project.config.json`, `appid`, `miniprogramRoot`, `tabBar`', '`wechatide` CLI', '`miniprogram-ci` preview/upload', 'message push (消息推送)', 'mini program SEO / search indexing', and 'CloudBase integration (`wx.cloud`)'. This matches the score-5 anchor ('multiple specific concrete actions; comprehensive coverage') and exceeds the score-4 anchor, which expects only 'several specific actions with minor gaps' — here coverage spans the full lifecycle from project structure to publishing to promotion.

Completeness

It explicitly answers 'what' (the enumerated capability list) and 'when' via the literal clause 'Use when users create, develop, modify, debug, preview, deploy, publish, or promote WeChat Mini Programs', plus an explicit exclusion clause ('NOT for Web frontend... pure backend services... UI-design-only tasks'). This is a direct match for the score-5 anchor ('clearly and explicitly answers both what AND when with concrete trigger phrases'); the score-4 anchor requires a 'when' that 'could be more explicit', which is not the case here.

Trigger Term Quality

Trigger coverage is comprehensive and bilingual: '小程序开发、调试、预览、发布', '消息推送', '客服消息', '云开发', '小程序搜索优化、页面收录、搜索推广', plus technical tokens users would echo verbatim ('project.config.json', 'appid', 'wechatide', 'wx.cloud', 'mpcrawler'). This matches the score-5 anchor (natural terms including synonyms and variations); the score-4 anchor ('a few natural terms missing') does not apply since both English and Chinese phrasings users would actually say are present.

Distinctiveness Conflict Risk

The niche is unambiguous (WeChat Mini Programs) and the description pre-empts the nearest conflicts by naming the skills to use instead: 'use web-development', 'use cloudrun-development / cloud-functions', 'use ui-design'. This matches the score-5 anchor ('clear niche with distinct triggers; minimal conflict risk') and goes beyond the score-4 anchor's 'minor overlap risk with closely related skills' by explicitly routing those overlaps away.
