Conciseness

The body is efficient and assumes Claude's competence — no known-concept explanations — with concrete file paths and a fill-in template. Minor trimming is possible (the 'Composing with Other Skills' section and some Key Rules restate the sibling-skill pointers from the Overview), so it fits anchor 4 rather than 5.

Actionability

Guidance is concrete for an instruction-only skill: named output files per phase, explicit exit criteria for Phase 1, a gate checklist for Phase 2, and a copy-ready PIPELINE_SUMMARY.md template. Per the rubric's code-vs-instruction note the absence of code is not penalized, but execution detail ultimately depends on the sibling skills, keeping it at anchor 4.

Workflow Clarity

Phases 0-5 are clearly sequenced with explicit validation checkpoints: Phase 0 checks whether FINAL_PROPOSAL.md exists, is stale, or misaligned; Phase 2 is a dedicated planning gate with the fallback 'If these answers are not crisp, tighten the final proposal first'; Phase 0 also has an in-doubt recovery rule ('prefer re-running aris-research-refine'). This matches the anchor-5 pattern of explicit validation steps and error-recovery feedback loops.

Progressive Disclosure

The body is a well-sectioned overview that defers stage detail to clearly signaled, one-level-deep sibling-skill links ('read these sibling skills only when needed'), and no bundle files exist to organize. It falls short of anchor 5 because the references point outside the bundle and the long Phase 4 summary template is inlined rather than split out.

Specificity

The description names the two chained workflows ('aris-research-refine' and 'aris-experiment-plan') and both concrete outputs ('focused final proposal plus detailed experiment roadmap'), going beyond 1-2 actions. It stops short of comprehensive coverage (e.g., review history and tracker deliverables are not mentioned), matching anchor 4 rather than 5.

Completeness

It explicitly answers both questions: the 'what' ('Run an end-to-end workflow that chains... to focused final proposal plus detailed experiment roadmap') and the 'when' ('Use when the user wants a one-shot pipeline... or asks to 串起来, build a pipeline, do it end-to-end...') with concrete trigger phrases, matching the anchor-5 example structure.

Trigger Term Quality

Natural trigger phrases are well covered: 'one-shot pipeline', 'build a pipeline', 'do it end-to-end', 'generate both the method and experiment plan together', plus the Chinese synonym '串起来'. A few natural variants (e.g., 'experiment design', 'research roadmap') are missing, so it fits anchor 4 rather than 5.

Distinctiveness Conflict Risk

The integrated-pipeline niche is mostly distinct, with triggers ('pipeline', 'end-to-end', '串起来', 'generate both') clearly differing from single-stage use. There is minor overlap risk because the description names the two component skills that exist as separate skills, fitting anchor 4 rather than 5.
