description: Step 5 of the PaperOrchestra pipeline (arXiv:2604.05018). Iteratively refine drafts/paper.tex by simulating peer review and applying targeted revisions, with strict accept/revert halt rules, deterministic 0-100 decision bands (Accept/Minor/Major/Reject) that drive a target-met early stop, and a Devil's Advocate concession-threshold guard that blocks acceptance on unresolved critical findings. Maintains a worklog and snapshots each iteration so revert is real, not symbolic. TRIGGER when the orchestrator delegates Step 5 or when the user asks to "refine the draft", "iterate on the paper", or "run peer review on this paper".

Content Refinement Agent (Step 5)

Faithful implementation of the Content Refinement Agent from PaperOrchestra (Song et al., 2026, arXiv:2604.05018, §4 Step 5, App. F.1 pp. 49–51).

**Cost: ~5–7 LLM calls** (App. B), typically ~3 refinement iterations, each consisting of one reviewer call and one revision call.

The paper highlights this step as one of the largest contributors to overall quality: refinement alone accounts for +19% (CVPR) and +22% (ICLR) absolute acceptance-rate improvement (Fig. 4). Get this step right.

Inputs

• `workspace/drafts/paper.tex` — output of Step 4
• `workspace/inputs/conference_guidelines.md`
• `workspace/inputs/experimental_log.md` — used as ground truth for the

hallucination check

• `workspace/citation_pool.json` / `workspace/refs.bib` — the allowed

bibliography

Outputs

• `workspace/refinement/iter1/`, `iter2/`, `iter3/` — per-iteration snapshots

containing `paper.tex`, `paper.pdf`, `review.json`, `score.json`

• `workspace/refinement/worklog.json` — append-only history of decisions
• `workspace/final/paper.tex` and `workspace/final/paper.pdf` — copy of the

best accepted snapshot

The refinement loop

prev_score = score(paper.tex)                  # baseline from initial draft
snapshot iter0/

for iter in 1..ITER_CAP (default 3):
    1. simulate_review(paper.tex) → review.json
       (uses `references/reviewer-rubric.md` rubric)

    2. apply_revision(paper.tex, review.json) → new_paper.tex
       (uses verbatim Refinement Agent prompt at `references/prompt.md`)

    3. snapshot iter<N>/ with new_paper.tex, review.json
       latexmk -pdf new_paper.tex → iter<N>/paper.pdf

    4. score(new_paper.tex) → curr_score

    5. decide via score_delta.py:
       - if curr.overall > prev.overall:                       ACCEPT
       - elif curr.overall == prev.overall and net_subaxis ≥0: ACCEPT
       - else:                                                 REVERT

    6. apply_worklog.py to append the decision

    7. if REVERT or no actionable weaknesses or iter == ITER_CAP: HALT

    paper.tex ← new_paper.tex   (only on ACCEPT)
    prev_score ← curr_score

cp <best iter>/paper.tex → workspace/final/paper.tex

The "best" snapshot at HALT is the one with the highest accepted overall score. On a REVERT halt, the best is the iteration immediately before the revert.

Step-by-step

0. Pre-refinement integrity gate

Before snapshotting or scoring the initial draft, run two gates in order:

**Gate A — AI failure modes** (load `references/ai-failure-modes.md`, runs once):

Load `references/ai-failure-modes.md` (which points to `skills/shared/ai_failure_modes.md`). Run all 7 checks against the draft and the inputs. This gate runs **once only**, at the start of iteration 1.

• CONFIRMED failure → write HALT entry to worklog.json, report to user, stop.
• SUSPECTED failure → add WARNING comment to paper.tex, log in worklog.json, continue.
• No failures → proceed.

**Gate B — Claim-evidence provenance** (runs once, WARN gate):

python skills/paper-orchestra/scripts/claim_evidence_gate.py \
    --paper workspace/drafts/paper.tex \
    --log   workspace/inputs/experimental_log.md \
    --out   workspace/claim_evidence_report.json

Exit 0 → PASS, proceed normally. Exit 1 → WARN: unsupported numeric claims found. Log in worklog.json as: `{gate: "claim_evidence", status: "WARN", unsupported_count: N, report: "workspace/claim_evidence_report.json"}` Pass the `unsupported` list from the report to the revision agent in Step 3 as an additional instruction: "The following numeric values appear in the paper but cannot be corroborated in experimental_log.md — verify or remove them: ..." Do NOT halt on Gate B warnings; the revision agent will address them.

**Gate C — Read research brief** (every run, no exit code):

If `workspace/research_brief.md` exists, read it before all reviewer calls. Pass the "Sections where evidence was thin" list from §4 as additional context to the Devil's Advocate reviewer. This surfaces the highest-risk sections for CRITICAL scrutiny.

0b. Snapshot the initial draft

python skills/content-refinement-agent/scripts/snapshot.py \
    --src workspace/drafts/paper.tex \
    --dst workspace/refinement/iter0/

This creates `iter0/paper.tex`. Then compile to `iter0/paper.pdf`:

cd workspace/refinement/iter0/ && latexmk -pdf -interaction=nonstopmode paper.tex

Score it (see Step 1 below) → `iter0/score.json`.

1. Simulate peer review

For each iteration N starting from 1:

**Writing quality pre-check (start of every iteration):** Load `references/writing-quality-check.md` and run the 5-category checklist (Categories A–E) against the current draft. Note violations and add them to the revision agenda.

**Update critique memory before the reviewer call** (iter N ≥ 2 only — skip for iter 1):

python skills/content-refinement-agent/scripts/update_critique_memory.py \
    --worklog workspace/refinement/worklog.json \
    --review  workspace/refinement/iter<N-1>/review.json \
    --iter    <N> \
    --out     workspace/refinement/critique_memory.json

This produces `critique_memory.json` with `focus_on` (persistent unresolved issues) and `do_not_reflag` (already-resolved issues). Inj
