The description names the domain (experiment evaluation) and some actions (judge claims, evaluate results against intended claims, route to next action), but the actions are somewhat abstract — 'pivot, supplement, or confirm' are named but not fully concrete in terms of what the skill actually does mechanically.

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

Includes some relevant terms like 'experiments complete', 'results', 'claims', 'ablations', 'paper', but misses common natural variations a user might say such as 'analyze results', 'interpret findings', 'evaluate outcomes', or 'experiment analysis'. The terms are somewhat niche and academic.

The skill occupies a clear niche — post-experiment claim evaluation with routing decisions — and is unlikely to conflict with general data analysis, paper writing, or experiment design skills. The specific workflow position (after experiments, before paper/ablations) makes it highly distinctive.

The skill is reasonably efficient but includes some unnecessary framing ('Experiments produce numbers; this gate decides what those numbers mean') and the 'When to Use' section explains things Claude could infer. The research wiki update section (Step 5) is quite lengthy and could be more terse. However, most content is substantive and non-redundant.

The skill provides a clear structured workflow with specific fields and routing logic, and the Codex prompt template is concrete. However, there's no truly executable code — the W&B snippet is illustrative, the spawn_agent block is pseudocode/template, and the integrity check and wiki update steps use pseudo-logic rather than executable commands. Key details like how to actually spawn the Codex agent or run the ARIS helper are left implicit.

The multi-step workflow is clearly sequenced (collect → judge → parse → check integrity → route → update wiki) with explicit validation via the secondary Codex judgment and integrity audit. The routing logic includes clear feedback loops: partial verdicts trigger supplementary experiments and re-evaluation, multiple partial rounds trigger scope narrowing. The conditional steps (3.5, 5) are clearly marked as skippable with explicit conditions.

The skill references external files (shared-references/experiment-integrity.md, shared-references/review-tracing.md, EXPERIMENT_LOG.md, etc.) which is good progressive disclosure. However, no bundle files are provided to verify these references exist, and the skill itself is quite long (~150+ lines) with the research wiki update section (Step 5) being very detailed inline content that could arguably be split into a separate reference file.
