Conciseness

The body is lean and efficient — compact schema tables, bare executable commands with flags, and JSON return formats — with no explanation of concepts Claude already knows; every token earns its place, matching the 'lean and efficient' anchor.

Actionability

All commands are copy-paste ready with full argument lists (e.g. 'bd-record record-creator --platform ... --notes <备注>'), each returns an explicit JSON contract (e.g. '{"ok": true, "id": <记录ID>}' or '{"ok": false, "error": "..."}'), and init is stated as idempotent — fully executable guidance covering the common cases.

Workflow Clarity

Both modes have an explicit check-before → skip-if-exists → record-after sequence with real checkpoints ('打开创作者主页前先用 check-creator 判断…已在记录中则跳过'), but there is no guidance for handling '{"ok": false, "error": ...}' responses or recovering from failed writes — a minor validation gap that keeps it below level 5.

Progressive Disclosure

Content is appropriately inline for a skill this compact, organized into clear sections (location, schema, commands, rules). Minor gap: the scripts/ bundle and the 'bd-record' PATH wrapper are never connected — the body says not to splice script paths but never explains how the wrapper maps to the bundled scripts, so organization is good but not fully self-navigating.

Specificity

Names the domain ("BD 线索与互动记录数据库（SQLite）") and two concrete actions ("已探索创作者去重、已互动帖子去重"), but omits recording leads, checking/ recording posts, and init — comprehensive coverage is missing, matching the 'domain plus 1-2 concrete actions' anchor rather than the fuller action list of level 4.

Completeness

The 'what' is reasonably clear (a BD lead/interaction SQLite database for dedup), but there is no 'Use when...' or equivalent trigger clause at all — per the judging guideline this caps completeness at 3, and it cannot reach 4 without any explicit 'when'.

Trigger Term Quality

Relevant domain keywords are present ("BD", "线索", "创作者", "帖子", "去重", "SQLite") but common natural variations users would say (e.g. "记录潜客", "已联系过的创作者", "check 重复") are missing, fitting the 'some relevant keywords but missing variations' anchor rather than the good coverage of level 4.

Distinctiveness Conflict Risk

The BD lead-hunting dedup niche is distinct with low overlap risk against typical skills; it falls short of level 5 only because the terse description leaves trigger boundaries under-specified, staying at 'mostly distinct; minor overlap risk'.
