Claim Matrix Rewriter Skill for Codex

Claim Matrix Rewriter (Evidence-first, NO PROSE)

Purpose: make outline/claim_evidence_matrix.md a navigation/index layer that is driven by evidence packs (not by outline bullets).

Key property: keep the legacy, gate-checked format so downstream QA can rely on stable markers:

• - Claim: (one per subsection)
• - Evidence: (>=2 per subsection)

Inputs

• outline/subsection_briefs.jsonl
• outline/evidence_drafts.jsonl
• citations/ref.bib

Outputs

• outline/claim_evidence_matrix.md

Non-negotiables

• NO PROSE: bullets only.
• No placeholders: no ..., unicode ellipsis (…), TODO, (placeholder), or <!-- SCAFFOLD -->.
• Claims are evidence-aware:
• fulltext-backed: may summarize comparisons
• abstract-only/title-only: must be provisional (no strong “dominant trade-offs” language)

Helper script

• uv run python .codex/skills/claim-matrix-rewriter/scripts/run.py --help
• uv run python .codex/skills/claim-matrix-rewriter/scripts/run.py --workspace <workspace>

Script

Quick Start

• uv run python .codex/skills/claim-matrix-rewriter/scripts/run.py --help
• uv run python .codex/skills/claim-matrix-rewriter/scripts/run.py --workspace <workspace>

All Options

• See --help.
• Requires: outline/subsection_briefs.jsonl, outline/evidence_drafts.jsonl, citations/ref.bib.

Examples

• Rewrite the matrix from evidence packs:
• Ensure outline/subsection_briefs.jsonl and outline/evidence_drafts.jsonl exist and blocking_missing is empty.
• Ensure citations/ref.bib exists and contains the cited keys.
• Run: uv run python .codex/skills/claim-matrix-rewriter/scripts/run.py --workspace <workspace>

Troubleshooting

Issue: cited keys are missing from citations/ref.bib

Fix:

• Run citation-verifier (or fix the upstream notes) so every referenced key exists before rewriting.

Issue: evidence packs still have blocking_missing

Fix:

• Fix upstream evidence (paper-notes / evidence-draft) first; the matrix should not “paper over” missing evidence.
