Conciseness

Every section (前置条件, 输入, 执行流程, 内容门禁, verdict branching, 更新状态, 产出) is purely operational with no concept explanations or padding; the single rationale line ("拆成两段的理由：speckit-analyze 是独立skill...") is a necessary design decision, and heavy details are delegated instead of duplicated. This matches the lean, competence-assuming top anchor.

Actionability

Concrete state-machine guidance: exact field updates ("更新 meta.yaml.phase 为 tasks-generated", "meta.yaml.history 追加成功记录，清空 meta.yaml.last_failure"), bounded retries ("最多 3 个 round"), and explicit re-entry targets. Not 5 because the executable SUBAGENT_PROMPT templates and shell commands are fully delegated to subagent-prompt-template.md §2.3+§2.4 rather than available inline; not 3 because the orchestration-level instructions are complete and specific with only template details delegated.

Workflow Clarity

Clear two-stage sequence with an explicit validation checkpoint (tasks-analyze compliance verdict), a content-gate checklist table (格式与可执行性, 用户价值切片, TDD 与验收, etc.), and explicit feedback loops: needs_fix → 同 attempt 内 round+1 (capped at 3), plan/spec_insufficient → 回退重入 with attempt-${N+1}.md. This matches the top anchor including error-recovery loops and a checklist.

Progressive Disclosure

All heavy material (prompt/report templates, verdict rules, reentry conventions, error handling) is delegated one level deep with precise section pointers (§2.3, §2.4) and consolidated in a 参考资料 section — well signaled and easy to navigate. Not 5 because references use parent-relative paths (../references/) and no bundle files exist alongside this SKILL.md to verify the targets resolve; not 3 because references are explicit, organized, and not buried.

Specificity

"调用 /speckit.tasks 生成全量任务，随后调用 /speckit.analyze 验证产物合规" and "两段命令通过两次 subagent 隔离执行" list several concrete, named operations with their outputs. Not 5 because coverage stops at two operations plus the isolation mechanism, unlike the comprehensive multi-action anchor; not 3 because the commands are explicitly named rather than vaguely described.

Completeness

The "what" is clear (task-generation phase: generate tasks.md, then verify compliance via two isolated subagents), but "when" is only weakly implied by the phase framing — there is no explicit "Use when..." clause or equivalent trigger guidance, which caps completeness at 3. Not 4 because no explicit usage condition is stated at all.

Trigger Term Quality

Terms like "迭代执行流水线", "/speckit.tasks", "subagent" are internal pipeline jargon; no natural phrases a user would say, no synonyms or file variations. Not 1 because the named slash-commands and file names (plan.md, research.md) are concrete anchors rather than entirely generic language; not 3 because no common natural-language trigger variations are present.

Distinctiveness Conflict Risk

Naming the specific phase and its two commands (speckit-tasks, speckit-analyze) carves a distinct niche among sibling pipeline-phase skills. Not 5 because the phase label alone ("迭代执行流水线任务生成阶段") overlaps conceptually with adjacent phases without stating what this skill does not cover; not 3 because the named commands and explicit outputs make it mostly distinct.
