Conciseness

The body is mostly skill-specific operational detail Claude would not already know (constants, evidence gates, reviewer receipts), but the AUTO_PROCEED blocking/non-blocking semantics are fully restated at Phase 1, Phase 2, and Phase 4.5 despite the dedicated 'Checkpoint execution rule' section, and the evidence-gate prose (e.g., '--provisional-advances is required because these same-family receipts are explicitly provisional') is dense and repetitive. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened'), not anchor 4 which has only minor trimmable instances.

Actionability

Concrete, near-executable commands are provided throughout: '/research-lit "$ARGUMENTS" — composed: idea-stage/IDEA_REPORT.md', 'python3 <resolved-run_state.py> mark-provisional . <run_id> novelty-check --verdict-id "<agent-or-trace-id>" --reviewer "<actual-reviewer-model>"', and '/render-html "idea-stage/IDEA_REPORT.md" --no-review', plus full output templates and concrete artifact paths. It falls short of anchor 5 because key placeholders (<resolved-run_state.py>, <run_id>) are only resolvable via the external '/research-pipeline' resolver pattern, leaving a dependency gap — anchor 4 ('mostly executable guidance; concrete code or commands with minor gaps').

Workflow Clarity

Phases 0 through 5.6 are clearly sequenced with explicit validation (the per-stage evidence gate with PASS/BLOCKED outcomes, verdict-gated 'done' marking, 'resume <run_id> from the first non-terminal phase') and genuine feedback loops (negative verdict → 're-run that reviewer-bearing phase'; reviewer unavailable → BLOCKED). This is anchor 4 ('clear sequence with most checkpoints present; minor validation gaps') rather than 5 because helper resolution and reviewer routing depend on external context ('the same resolver pattern as /research-pipeline') that makes the flow not fully self-contained or trivially followable.

Progressive Disclosure

Structure is good: clear section headers, and one-level-deep references that are clearly signaled with markdown links ('[output-composition.md](../shared-references/output-composition.md)', the Output Protocols block, '[Selectable Reviewers](../shared-references/reviewer-backends.md)'). However, the body is a monolithic ~490-line file with the Research Brief template, REF_PAPER_SUMMARY template, final report template, and the dense evidence-gate/receipt mechanics all inlined, content that would be better split into separate files — anchor 4 ('good structure; most content appropriately placed; references mostly clear; minor organization gaps'), short of anchor 5's clean overview-plus-split pattern.

Specificity

The description names the domain and one concrete transformation — "go from a broad research direction to validated, pilot-tested ideas" — but never enumerates the pipeline's actual actions (literature survey, brainstorming, novelty verification, critical review, refinement). This matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive'), falling short of anchor 4 which expects several specific listed actions.

Completeness

Both parts are present: the 'what' ("Full idea discovery pipeline to go from a broad research direction to validated, pilot-tested ideas") and an explicit 'Use when user says...' clause with concrete trigger phrases. It exceeds anchor 4's typical weakness (the 'when' here is very explicit), but does not reach anchor 5 because the 'what' is a single abstract pipeline sentence rather than concrete stated capabilities, matching anchor 4 ('both what and when; one could be more explicit').

Trigger Term Quality

Explicit natural phrases users would actually say are quoted: "找idea全流程", "idea discovery pipeline", "从零开始找方向", plus "complete idea exploration workflow". Coverage is good but misses common English variations like 'find research ideas' or 'brainstorm research topics', fitting anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The quoted triggers ("找idea全流程", "从零开始找方向") are distinctive and niche-specific, but the framing "Workflow 1" and "complete idea exploration workflow" overlaps with closely related sibling skills the body itself invokes (/research-pipeline, /research-lit, /idea-creator). This is anchor 4 ('mostly distinct; minor overlap risk with closely related skills'), not 5, since a user asking for a general 'research pipeline' could plausibly hit either skill.
