Conciseness

The body is lean — no explanations of concepts Claude already knows, tight bullets, and detail correctly pushed to reference files. It falls short of 5 due to duplication (trigger rules appear in both the CAUTION block and the 触发判断 section, repeating the frontmatter) and a time-sensitive line ('> 更新：2026-02-13' plus 'v3.0' in the title) that is not in a deprecation/old-patterns section.

Actionability

Guidance is largely executable for an instruction skill: concrete Phase 0 snapshot fields, a tiered execution path per task complexity, quantified rules (2-Action, 3-Strike), and a full directory layout with required/optional files. It misses 5 because two operational gaps remain: nothing explains how to bootstrap .taskflow/ or maintain index.json, and the bundle's task-lifecycle.py / session-catchup.py scripts — which would be the natural executable commands for task creation and archiving — are never referenced.

Workflow Clarity

The Phase 0 → Execution → Completion sequence is clear, with explicit checkpoints (2-Action Rule checkpoint updates, 3-Strike escalation with an excluded-options list, final re-grounding against anchor.md completion criteria) and genuine feedback loops (drift → pause → ask user). It stays below 5 because the archive step ('移入 archive/') and the .taskflow/ initialization are underspecified — no command or procedure is given for either.

Progressive Disclosure

Good structure: SKILL.md is a genuine overview with a dedicated 按需加载 (load-on-demand) section plus a reference table, all 7 linked bundle files (4 references, 3 templates) exist and are one level deep. Scored against the actual bundle per the guidelines, it misses 5 because the two scripts in scripts/ (task-lifecycle.py, session-catchup.py) are orphaned — never mentioned anywhere in SKILL.md, so they are undiscoverable from the index.

Specificity

The description names the domain ("复杂任务管理系统" — complex task management system) and one concrete mechanism ("必须使用项目根目录下的 .taskflow/ 目录"), but never states what the skill actually does (anchor/checkpoint phases, re-grounding, etc.). It matches the anchor 'names domain and 1-2 concrete actions, but not comprehensive' rather than 4, since the functional actions are entirely absent; it is above 2 because the .taskflow/ directory mandate and read-first rule are concrete.

Completeness

Both 'what' and 'when' are explicitly present: 'what' is "复杂任务管理系统" with the .taskflow/ directory mechanism, and 'when' is a two-item trigger list with concrete user phrases — the explicit trigger guidance means the completeness cap of 3 does not apply. It does not reach 5 because the 'what' is generic ('task management system') and omits the skill's core capabilities, leaving it weaker than the anchor-5 example's concrete what+when pairing.

Trigger Term Quality

Natural user phrases are present: "用户说'帮我想想/重构/升级/实现'" plus technical conditions like "多文件变更、规划设计、新功能开发" — good coverage of terms a user would actually say. It falls short of 5 because there is no synonym expansion (e.g., "设计方案", "新功能", English equivalents) and the technical conditions are tersely phrased.

Distinctiveness Conflict Risk

The domain (.taskflow task-management protocol) is specific and clearly distinct from domain skills, but the triggers "多文件变更" (multi-file changes), "规划设计" (planning/design), "新功能开发" (new feature development), and "帮我想想" (help me think) fire on a large share of ordinary coding sessions, creating real overlap risk with planning/refactoring workflows. It is above 2 because the description carves out a clear niche and explicitly disambiguates against the built-in artifact directory.
