The description names the domain (experiment evaluation) and some actions ('judge what claims the results support', 'routes to the next action: pivot, supplement, or confirm'), but the concrete actions are somewhat abstract rather than listing specific technical operations.

Clearly answers both 'what' (a secondary Codex agent evaluates results against intended claims and routes to next action) and 'when' (after experiments finish, before writing the paper or running ablations), with explicit temporal triggers and a 'Use when' clause.

Includes some relevant terms like 'experiments complete', 'results', 'claims', 'ablations', 'writing the paper', but misses common variations users might say such as 'evaluate results', 'interpret findings', 'statistical significance', or 'experiment analysis'. The terms are moderately natural but not comprehensive.

The description carves out a very specific niche — post-experiment claim evaluation with routing decisions (pivot, supplement, confirm) — that is unlikely to conflict with other skills like data analysis, paper writing, or experiment design skills.

The skill is mostly efficient but includes some unnecessary elaboration. Phrases like 'Experiments produce numbers; this gate decides what those numbers mean' and the 'When to Use' section explain context Claude can infer. The workflow steps themselves are reasonably tight, but the overall document could be trimmed by ~20%.

The skill provides concrete, actionable guidance throughout: specific API calls for W&B data collection, a complete prompt template for the secondary agent, structured output fields to extract, and explicit routing actions for each verdict outcome. The instructions are specific enough to execute directly.

The four-step workflow is clearly sequenced (Collect → Judge → Parse → Route) with explicit branching logic for each verdict. The partial verdict path includes a feedback loop (re-run after supplementary experiments), and there's a clear escalation path for repeated partial verdicts. Validation is embedded via the external reviewer judgment step.

The skill references external files like `findings.md`, `IDEA_CANDIDATES.md`, `EXPERIMENT_LOG.md`, and `/ablation-planner` but doesn't provide clear navigation links or explain what those contain. The content is well-structured with headers but is somewhat long for a single file—the detailed prompt template and routing logic could potentially be split out.
