Conciseness

The body is dense operational instruction rather than concept explanation, but there is noticeable duplication: the external-cadence/heartbeat doctrine appears both in the opening blockquote and again in full in the "Overnight heartbeat" section, and the canonical helper-resolution chain (`.aris/tools → tools → $ARIS_REPO`) is stated three times, including a 7-line shell block. This fits the 3 anchor (mostly efficient but could be tightened) better than 2 (no pervasive padding) or 4 (only minor trims needed).

Actionability

Mostly executable guidance: exact slash-command invocations with argument passthrough (e.g. `/experiment-bridge "$CHOSEN_IDEA_TITLE" — code review: $CODE_REVIEW, base repo: $BASE_REPO`), concrete `run_state.py` invocations, and a filled-in report template. Minor gaps keep it below 5: state transitions are written in shorthand (`set <run_id> <phase> running` without the script prefix) and variables like `$ROOT`, `$RUN_ID`, `$STAGE`, `$N_NEW_FINDINGS` are used without being defined anywhere.

Workflow Clarity

Stages 1-5 are clearly sequenced with explicit gates, each gate's blocking vs non-blocking behavior is spelled out under AUTO_PROCEED, acceptance criteria are tabulated per phase, and there are feedback loops throughout (re-run failed stages, re-audit done-but-unaccepted stages, review rounds with an explicit STOP condition, bounded 3-attempt debugging). This matches the 5 anchor (clear sequence, explicit validation, feedback loops, checklists).

Progressive Disclosure

References are clearly signaled with markdown links (external-cadence.md, resumable-runs.md, output-versioning/manifest/language protocols), but no bundle files exist in the skill directory and the linked shared-references/templates are not resolvable here. Moreover, material that belongs in those referenced files — the full heartbeat doctrine and the multi-line shell helper-resolution chain — is duplicated inline in the ~390-line body. This fits the 3 anchor (references present, but content that should be separate is inline) rather than 4's 'appropriately placed' or 2's 'references buried'.

Specificity

The description names concrete pipeline actions — "from a broad research direction through idea discovery, experiments, and review all the way to a polished paper PDF" — listing several specific stages. It falls short of a 5 because the individual actions are stage names rather than fully enumerated capabilities, and short of 3 because it clearly covers the whole lifecycle, not just 1-2 actions.

Completeness

Both halves are explicit: the "what" is the full pipeline from research direction to polished paper PDF, and the "when" is a literal "Use when user says ..." clause with concrete trigger phrases. This matches the 5 anchor (explicit what AND when with concrete trigger phrases) and exceeds the 4 anchor where 'when' is present but less specific.

Trigger Term Quality

Triggers include natural phrases users would say: "全流程", "full pipeline", "从找idea到投稿", "end-to-end research", plus the paraphrase "wants the complete autonomous research lifecycle". Coverage is good with bilingual synonyms, but common single-stage variations a user might actually say (e.g. "write my paper", "run the whole pipeline", "投稿") are only partially represented, keeping it below the comprehensive 5 anchor.

Distinctiveness Conflict Risk

The pipeline framing ("full end-to-end research pipeline", "complete autonomous research lifecycle") carves a clear orchestrator niche distinct from its component skills (idea discovery, experiments, review, paper writing). Minor overlap risk remains: a user asking only for "end-to-end research" during a single sub-stage could plausibly trigger this skill instead of a component skill, so it is not the minimal-conflict 5.
