Codex MCP evaluates results against intended claims and routes to next action (pivot, supplement, or confirm). Use after experiments finish — before writing the paper or running ablations.

Experiments produce numbers; this gate decides what those numbers mean. Collect results from available sources, get an objective judgment, then route based on the verdict.
gpt-5.4 - Used via a secondary Codex agent for objective claim assessment.Gather experiment data from whatever sources are available in the project:
wandb.Api().run("<entity>/<project>/<run_id>").history() - metrics, training curves, comparisonsEXPERIMENT_LOG.md - full results table with baselines and verdictsEXPERIMENT_TRACKER.md - check which experiments are done vs still runningssh server "tail -100 /path/to/training.log" if no other sourcedocs/research_contract.md or project notes - intended claims and experiment designAssemble the key information:
Send the collected results to a secondary Codex agent for objective evaluation:
textspawn_agent: model: REVIEWER_MODEL reasoning_effort: xhigh message: | RESULT-TO-CLAIM EVALUATION I need you to judge whether experimental results support the intended claim. Intended claim: [the claim these experiments test] Experiments run: [list experiments with method, dataset, metrics] Results: [paste key numbers, comparison deltas, significance] Baselines: [baseline numbers and sources - reproduced or from paper] Known caveats: [any confounding factors, limited datasets, missing comparisons] Please evaluate: 1. claim_supported: yes | partial | no 2. what_results_support: what the data actually shows 3. what_results_dont_support: where the data falls short of the claim 4. missing_evidence: specific evidence gaps 5. suggested_claim_revision: if the claim should be strengthened, weakened, or reframed 6. next_experiments_needed: specific experiments to fill gaps (if any) 7. confidence: high | medium | low Be honest. Do not inflate claims beyond what the data supports. A single positive result on one dataset does not support a general claim.
If delegation is unavailable, run the same evaluation locally and mark the verdict [pending external review] instead of blocking the pipeline.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted, and 19 counted toward the lift figure. The other 3 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +36 percentage points is the difference between those two pass rates over the 19 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
| Model | Method | Date | Lift |
