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. 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:

Load references/reviewer-rubric.md as the system prompt for the simulated reviewer call. The reviewer reads iter<N-1>/paper.pdf (or paper.tex if your host LLM lacks PDF input) and produces a JSON of strengths, weaknesses, questions, and per-axis scores.

The rubric is structured to mimic AgentReview (Jin et al., 2024) — the paper's chosen evaluator. We ship a faithful rubric in the references directory; the host agent's LLM does the actual reviewing.

Save to workspace/refinement/iter<N>/review.json.

2. Score the draft

The reviewer call produces both qualitative feedback and a per-axis score:

{
  "axis_scores": {
    "scientific_depth":     {"score": 65, "justification": "..."},
    "technical_execution":  {"score": 70, "justification": "..."},
    "logical_flow":         {"score": 60, "justification": "..."},
    "writing_clarity":      {"score": 55, "justification": "..."},
    "evidence_presentation":{"score": 72, "justification": "..."},
    "academic_style":       {"score": 68, "justification": "..."}
  },
  "overall_score": 64.5,
  "strengths": [...],
  "weaknesses": [...],
  "questions": [...]
}

Save to iter<N>/score.json. (Combined with review.json if your host emits one document; the schemas overlap.)

3. Apply revision

Load the verbatim Content Refinement Agent prompt at references/prompt.md. Prepend the Anti-Leakage Prompt. Inputs:

• paper.tex — current draft
• paper.pdf — compiled PDF (multimodal context if available)
• conference_guidelines.md
• experimental_log.md — ground truth for numeric claims
• worklog.json — history of previous changes
• citation_pool.json — the allowed bibliography
• reviewer_feedback — the JSON from Step 1

The prompt instructs the model to address weaknesses, integrate question answers, and emit two output blocks:

1. A worklog JSON {addressed_weaknesses[], integrated_answers[], actions_taken[]}
2. The full revised LaTeX code

Save the revised LaTeX as iter<N>/paper.tex. Append the worklog JSON to workspace/refinement/worklog.json via apply_worklog.py.

4. Compile and re-score

cd workspace/refinement/iter<N>/ && latexmk -pdf -interaction=nonstopmode paper.tex

Then re-run the simulated review on the new draft → updated score.json for the new iteration. (This is the "re-score after revision" call.)

5. Apply the accept/revert decision

The calling loop must track CONSECUTIVE_SMALL (starts at 0) and pass it on each call so score_delta.py can detect the plateau:

python skills/content-refinement-agent/scripts/score_delta.py \
    --prev workspace/refinement/iter<N-1>/score.json \
    --curr workspace/refinement/iter<N>/score.json \
    --plateau-threshold 1.0 \
    --plateau-streak 3 \
    --consecutive-small $CONSECUTIVE_SMALL \
    > workspace/refinement/iter<N>/delta.json
 
EXIT=$?
# Update streak for next iteration:
CONSECUTIVE_SMALL=$(python3 -c "
import json
d = json.load(open('workspace/refinement/iter<N>/delta.json'))
print(d['consecutive_small'])
")

Exit codes:

• 0 — ACCEPT (overall improved or tied with non-negative net sub-axis, no plateau)
• 1 — REVERT (overall decreased)
• 2 — REVERT (tied overall, but net sub-axis change negative)
• 4 — HALT_PLATEAU (accepted but N consecutive iterations below threshold — stop early)

Behavior:

• ACCEPT (exit 0): keep iter<N>/paper.tex as the new best. Continue to iter N+1.
• REVERT (exit 1 or 2): copy iter<N-1>/paper.tex back as canonical, halt.
• HALT_PLATEAU (exit 4): keep current (it was accepted), but stop — further

iterations are unlikely to yield meaningful gains. In practice ~85% of refinement gain comes in iteration 1; the plateau fires when subsequent iterations improve by less than 1 point for 3 consecutive rounds.

Always log the decision via apply_worklog.py --decision ....

6. Halt rules

Halt the loop when ANY of these is true:

1. Iteration count reaches ITER_CAP (default 3).
2. score_delta.py returned exit code 1 or 2 (REVERT).
3. The simulated reviewer's weaknesses list is empty (no actionable

feedback to apply).

1. score_delta.py returned exit code 4 (HALT_PLATEAU — plateau early-stop).

7. Promote the best snapshot

Identify the iteration with the highest accepted overall_score (this may be the latest accepted iteration, OR an earlier one if a later iteration was reverted). Copy:

cp workspace/refinement/iter<best>/paper.tex workspace/final/paper.tex
cp workspace/refinement/iter<best>/paper.pdf workspace/final/paper.pdf

Then in the final report, tell the user:

• How many iterations were run
• The final overall score
• The score trajectory (e.g., "iter0 64.5 → iter1 67.3 (accept) → iter2 69.1 (accept) → iter3 68.9 (revert, halt)")
• Which iteration was promoted

Critical safety constraints (App. F.1 page 50–51)

The paper explicitly notes that early versions of the Refinement Agent "exploited the automated reviewer's scoring function by superficially listing missing baselines as limitations to artificially inflate acceptance scores." The verbatim prompt forbids this. You must honor it:

• Ignore reviewer requests for new experiments, ablations, or baselines.

The Refinement Agent's job is presentation, not new science. If the reviewer asks for missing data, simply skip those points — do NOT add fabricated experiments, do NOT add a "future work" item promising them.

• Never explicitly state a limitation. The phrase "we acknowledge as a

limitation that..." is forbidden. The model can address weaknesses through clearer explanation, but must not game the evaluator by listing them defensively.

• All numeric claims MUST be verified against `experimental_log.md`.

The agent cannot introduce new numbers, only re-present existing ones.

These rules prevent reward hacking and keep the refinement loop honest.
