Conciseness

The body is mostly efficient and free of padding, but the stop-before-commit/authority rule is restated across Philosophy ("does not authorize implementation, staging, commits, Linear updates, or closure"), Procedure step 6, Execution Boundaries, Failure Mode, Gotchas, and Validation Gates. Consolidating these overlapping safety restatements would tighten the document noticeably.

Actionability

The numbered procedure, exact output field names (slack_policy, stop_rule_status, next_safe_action), and a fully filled Output Template with an exact command ("bash scripts/verify-work.sh --fast") give mostly executable guidance. Minor gaps remain where steps defer to named contracts ("run the phase gate contract", "apply the context-disposition policy") without any inline summary of what those entail.

Workflow Clarity

The 6-step procedure is clearly sequenced, the fail-fast rule ("stop at the first failed gate and do not proceed until the blocker is fixed") provides an explicit feedback loop, and Validation Gates plus the Failure Mode recovery step form a checklist with error recovery. Validation for the risky operations is explicitly present, so the destructive-operation cap does not apply.

Progressive Disclosure

The References section is clearly signaled and one level deep, and references/phase-gate-contract.md, references/contract.yaml, and references/evals.yaml exist in the bundle. However, three referenced paths (../../references/stage-arc-boundary-contract.md, ../../references/subagent-call-contract.md, ../../references/deferred-context-index.md) do not resolve in the bundle, and references/task-profile.json is present but never referenced, leaving organization gaps beyond the minor ones allowed at level 4.

Specificity

The description lists several concrete routing actions ("check the approved plan, reuse or create a 10-minute continuation only with authority, run phase gates, delegate the active slice to he-work, and stop before commit or tracker closure"), but terms like "HE phase work" and "he-work" are unresolved internal jargon that leaves minor gaps in coverage. It is above level 3 because it names the domain plus five specific actions, but below level 5 because comprehensiveness is diluted by jargon a reader cannot decode.

Completeness

It explicitly answers both "what" (routes old phase-heartbeat requests into HE phase work with enumerated actions) and "when" (three concrete user trigger phrases). It clearly matches the level 5 anchor rather than level 4, since the when clause is explicit and specific rather than weakly implied.

Trigger Term Quality

"Use when a user says phase heartbeat, keep this PR moving, or continue phases" provides natural phrases a user would actually say. Good coverage, but common variations such as "recurring phase work", "heartbeat loop", or "10 minute continuation" are missing, keeping it just below comprehensive.

Distinctiveness Conflict Risk

Triggers like "phase heartbeat" carve a fairly distinct niche, but the skill family it belongs to (he-work, he-plan, he-spec, he-phase-work) shares trigger space around "continue phases" and phase continuation requests, creating minor overlap risk with closely related skills.
