Conciseness

Dense and imperative with essentially no filler ('决策层跑偏的根因不是提示词不够强，而是状态没有物化'), but the gate-1 trigger-event list is stated twice nearly verbatim (核心规则 item 2 and 阶段 3) and the '零 token 原则' paragraph partially restates the per-gate annotations — trimmable duplication, so above the midpoint but not the lean ideal of 5.

Actionability

Mostly executable: real script invocations ('gate_scope_lock.py', 'gate_deadband.py', 'python scripts/run_tests.py'), a concrete polling call ('job_output(job_id, wait=true, timeout_ms=60000)'), and a full anchor-JSON field contract. Minor gaps: every reference to 'templates/raw_evidence_anchors.json' and 'templates/adversarial-audit-brief.md' points at files that do not exist in the bundle, and 'create_goal' is invoked without any definition, so a few steps cannot be executed as written.

Workflow Clarity

Six phases are explicitly sequenced with validation gates and rollback loops throughout: gate 2 must pass before acceptance ('❌ 冲突不得进入验收'), audit ⚠️/❌ must be resolved before the next checkpoint, DEFENSE_DRIFT triggers rollback to the last clean checkpoint, recovery enforces a hard read order ('先锚后摘要'), and a 验证 section provides runnable regression commands. This matches the clear-sequence-with-explicit-validation-and-error-recovery anchor.

Progressive Disclosure

The single-file structure is coherent and script references (gate_consistency/cost/selfcheck/scope_lock/deadband/run_tests) resolve to real files, but the body repeatedly points to a 'templates/' directory (raw_evidence_anchors.json, adversarial-audit-brief.md) that is absent from the bundle — broken one-level references. It is not a 4 because navigation to core artifacts dead-ends; not a 2 because the remaining structure and references are mostly appropriate.

Specificity

Names the domain (DSH long-horizon tasks) and lists five concrete mechanisms ('原始证据锚、对抗式对齐审计、跨包一致性校验、成本比对、防御自检') plus concrete actions ('checkpoint 记录与恢复'), but says '五道闸门' while the body now defines seven gates (scope lock and deadband interceptor are absent), a minor coverage gap.

Completeness

Explicitly answers both: what ('为决策层加装五道防偏闸门' with named gates and the harms prevented: '目标漂移、验收失真与摘要偏差') and when ('用于跨会话长任务、多 worker 并行、审计类任务、成本敏感任务的 checkpoint 记录与恢复，以及任何需要...的执行场景'). Not below 4 because the 'when' clause is explicit with concrete trigger phrases; not applicable above 5.

Trigger Term Quality

Natural trigger phrases are present ('跨会话长任务', '多 worker 并行', '审计类任务', '成本敏感任务', 'checkpoint 记录与恢复') and would plausibly appear in a user's request, but a few common variations (e.g. 断点恢复, 验收) only appear in the frontmatter triggers rather than the description itself.

Distinctiveness Conflict Risk

The '决策层不跑偏' / evidence-anchor framing carves a clear niche distinct from generic task-management skills, but '长程任务/checkpoint 记录与恢复' overlaps with the execution-discipline/task-mode-router skills it declares as dependencies — minor overlap risk, not the clear-niche minimal-conflict case of a 5.
