Auto Paper Improvement Loop

Override for Codex users who want Gemini, not a second Codex agent, to act as the reviewer. Install this package after skills/skills-codex/*.

Auto Paper Improvement Loop: Review → Fix → Recompile

Gemini overlay assurance: review_independence: cross-family and acceptance_status: accepted.

Autonomously improve the paper at: $ARGUMENTS

Context

This skill is designed to run after Workflow 3 (/paper-plan → /paper-figure → /paper-write → /paper-compile). It takes a compiled paper and iteratively improves it through external LLM review.

Unlike /auto-review-loop (which iterates on research — running experiments, collecting data, rewriting narrative), this skill iterates on paper writing quality — fixing theoretical inconsistencies, softening overclaims, adding missing content, and improving presentation.

Constants

• MAX_ROUNDS = 2 — Two rounds of review→fix→recompile. Empirically, Round 1 catches structural issues (4→6/10), Round 2 catches remaining presentation issues (6→7/10). Diminishing returns beyond 2 rounds for writing-only improvements.
• REVIEWER_MODEL = gemini-review — Gemini reviewer invoked through the local gemini-review MCP bridge. Set GEMINI_REVIEW_MODEL if you need a specific Gemini model override.
• REVIEW_LOG = PAPER_IMPROVEMENT_LOG.md — Cumulative log of all rounds, stored in paper directory.
• HUMAN_CHECKPOINT = false — When true, pause after each round's review and present score + weaknesses to the user. The user can approve fixes, provide custom modification instructions, skip specific fixes, or stop early. When false (default), runs fully autonomously.

💡 Override: /auto-paper-improvement-loop "paper/" — human checkpoint: true

Inputs

1. Compiled paper — paper/main.pdf + LaTeX source files
2. All section .tex files — concatenated for review prompt

State Persistence (Compact Recovery)

If the context window fills up mid-loop, Codex auto-compacts. To recover, this skill writes PAPER_IMPROVEMENT_STATE.json after each round:

{
  "current_round": 1,
  "thread_id": "019ce736-...",
  "last_score": 6,
  "status": "in_progress",
  "timestamp": "2026-03-13T21:00:00"
}

On startup: if PAPER_IMPROVEMENT_STATE.json exists with "status": "in_progress" AND timestamp is within 24 hours, read it + PAPER_IMPROVEMENT_LOG.md to recover context, then resume from the next round. Otherwise (file absent, "status": "completed", or older than 24 hours), start fresh.

After each round: overwrite the state file. On completion: set "status": "completed".

Workflow

Step 0: Preserve Original

cp paper/main.pdf paper/main_round0_original.pdf

Step 1: Collect Paper Text

Concatenate all section files into a single text block for the review prompt:

# Collect all sections in order
for f in paper/sections/*.tex; do
    echo "% === $(basename $f) ==="
    cat "$f"
done > /tmp/paper_full_text.txt

Step 2: Round 1 Review

Send the full paper text to Gemini review:

mcp__gemini-review__review_start:
  prompt: |
    You are reviewing a [VENUE] paper. Please provide a detailed, structured review.

    Judge claim calibration in BOTH directions. Recommend narrowing only when the
    current scope or modality exceeds the evidence; do not ask for extra hedges
    around a supported result. Flag stacked hedges, self-defence ("we do not
    claim"), instruction confessions ("we do not address X"), and generic caveats
    outside Limitations as writing defects to remove. Tone fixes must never alter
    facts, negation, modality, scope, comparison direction, or numbers.
    Also flag narrative defects: a progress-report structure ("we first tried
    A, then B"), a story built on a metric the method loses, results narrated
    as defeats ("underperforms", "fails to surpass") instead of explained as a
    goal difference or tradeoff, experiments with no argumentative duty, an
    abstract or introduction that opens on background or implementation
    instead of problem -> gap -> idea -> strongest result, and a conclusion
    that ends on new self-negation. The fix is reframing and cutting where
    the evidence supports the reframing; a genuine weakness is stated
    neutrally and kept in Limitations. Never delete unfavorable numbers from
    tables, and never dress a weakness as a tradeoff.

    ## Full Paper Text:
    [paste concatenated sections]

    ## Review Instructions
    Please act as a senior ML reviewer ([VENUE] level). Provide:
    1. **Overall Score** (1-10, where 6 = weak accept, 7 = accept)
    2. **Summary** (2-3 sentences)
    3. **Strengths** (bullet list, ranked)
    4. **Weaknesses** (bullet list, ranked: CRITICAL > MAJOR > MINOR)
    5. **For each CRITICAL/MAJOR weakness**: A specific, actionable fix
    6. **Missing References** (if any)
    7. **Verdict**: Ready for submission? Yes / Almost / No

    Focus on: theoretical rigor, claims vs evidence alignment, writing clarity,
    self-containedness, notation consistency.

After this start call, immediately save the returned jobId and poll mcp__gemini-review__review_status with a bounded waitSeconds until done=true. Treat the completed status payload's response as the reviewer output, and save the completed threadId for any follow-up round.

Save the returned jobId, poll mcp__gemini-review__review_status until done=true, then save the completed threadId for Round 2.

Step 2b: Human Checkpoint (if enabled)

Skip if HUMAN_CHECKPOINT = false.

Present the review results and wait for user input:

📋 Round 1 review complete.

Score: X/10 — [verdict]
Key weaknesses (by severity):
1. [CRITICAL] ...
2. [MAJOR] ...
3. [MINOR] ...

Reply "go" to implement all fixes, give custom instructions, "skip 2" to skip specific fixes, or "stop" to end.

Parse user response same as /auto-review-loop: approve / custom instructions / skip / stop.

Step 3: Implement Round 1 Fixes

Parse the review and implement fixes by severity:

Priority order:

1. CRITICAL fixes (assumption mismatches, internal contradictions)
2. MAJOR fixes (overclaims, missing content, notation issues)
3. MINOR fixes (if time permits)

Before applying any fix: calibrate claims to evidence and state them directly; generic caveats belong in Limitations only; writing instructions are never manuscript content; tone edits never change what the paper knows.

Common fix patterns:

Step 4: Recompile Round 1

cd paper && latexmk -C && latexmk -pdf -interaction=nonstopmode -halt-on-error main.tex
cp main.pdf main_round1.pdf

Verify: 0 undefined references, 0 undefined citations.

Step 5: Round 2 Review

Start a fresh mcp__gemini-review__review_start — do not reuse the Round 1 thread, do not send fix summaries. The reviewer re-reads the recompiled paper cold; executor notes are not evidence, and "since your last review, we implemented..." is exactly the self-report path that lets fixes be graded on their description instead of their substance:

mcp__gemini-review__review_start:
  prompt: |
    You are reviewing a [VENUE] paper (Round 2 — fresh read of the current
    manuscript; judge only what is on the page).

    Judge claim calibration in BOTH directions. Recommend narrowing only when the
    current scope or modality exceeds the evidence; do not ask for extra hedges
    around a supported result. Flag stacked hedges, self-defence ("we do not
    claim"), instruction confessions ("we do not address X"), and generic caveats
    outside Limitations as writing defects to remove. Tone fixes must never alter
    facts, negation, modality, scope, comparison direction, or numbers.
    Also flag narrative defects: a progress-report structure ("we first tried
    A, then B"), a story built on a metric the method loses, results narrated
    as defeats ("underperforms", "fails to surpass") instead of explained as a
    goal difference or tradeoff, experiments with no argumentative duty, an
    abstract or introduction that opens on background or implementation
    instead of problem -> gap -> idea -> strongest result, and a conclusion
    that ends on new self-negation. The fix is reframing and cutting where
    the evidence supports the reframing; a genuine weakness is stated
    neutrally and kept in Limitations. Never delete unfavorable numbers from
    tables, and never dress a weakness as a tradeoff.

    [full current paper text]

    Please provide the same structured format:
    Score, Summary, Strengths, Weaknesses, Actionable fixes, Verdict.

After this start call, immediately save the returned jobId and poll mcp__gemini-review__review_status with a bounded waitSeconds until done=true. Treat the completed status payload's response as the reviewer output, and save the completed threadId for any follow-up round.

Step 5b: Human Checkpoint (if enabled)

Skip if HUMAN_CHECKPOINT = false. Same as Step 2b — present Round 2 review, wait for user input.

Step 6: Implement Round 2 Fixes

Same process as Step 3. Typical Round 2 fixes:

• Add controlled synthetic experiments validating theory
• Re-check calibration in both directions: narrow genuine overclaims, state supported claims directly, consolidate scattered generic caveats into Limitations — and do not re-soften claims the evidence already supports
• Formalize informal arguments (e.g., truncation → formal proposition)
• Make Limitations more specific only when a material limit is missing

Step 7: Recompile Round 2

cd paper && latexmk -C && latexmk -pdf -interaction=nonstopmode -halt-on-error main.tex
cp main.pdf main_round2.pdf

Step 8: Format Check

After the final recompilation, run a format compliance check:

# 1. Page count vs venue limit
PAGES=$(pdfinfo paper/main.pdf | grep Pages | awk '{print $2}')
echo "Pages: $PAGES (limit: 9 main body for ICLR/NeurIPS)"

# 2. Overfull hbox warnings (content exceeding margins)
OVERFULL=$(grep -c "Overfull" paper/main.log 2>/dev/null || echo 0)
echo "Overfull hbox warnings: $OVERFULL"
grep "Overfull" paper/main.log 2>/dev/null | head -10

# 3. Underfull hbox warnings (loose spacing)
UNDERFULL=$(grep -c "Underfull" paper/main.log 2>/dev/null || echo 0)
echo "Underfull hbox warnings: $UNDERFULL"

# 4. Bad boxes summary
grep -c "badness" paper/main.log 2>/dev/null || echo "0 badness warnings"

Auto-fix patterns:

If any overfull hbox > 10pt is found, fix it and recompile before documenting.

Step 9: Document Results

Create PAPER_IMPROVEMENT_LOG.md in the paper directory:

# Paper Improvement Log

Output Protocols

Follow these shared protocols for all output files:

• Output Versioning Protocol — write timestamped file first, then copy to fixed name
• Output Manifest Protocol — log every output to MANIFEST.md
• Output Language Protocol — respect the project's language setting

Key Rules

• Large file handling: If the Write tool fails due to file size, immediately retry using Bash (cat << 'EOF' > file) to write in chunks. Do NOT ask the user for permission — just do it silently.

• Preserve all PDF versions — user needs to compare progression

• Save FULL raw review text — do not summarize or truncate Gemini reviewer responses

• Use mcp__gemini-review__review_reply_start plus mcp__gemini-review__review_status for Round 2 to maintain conversation context

• Always recompile after fixes — verify 0 errors before proceeding

• Do not fabricate experimental results — synthetic validation must describe methodology, not invent numbers

• Respect the paper's claims — narrow genuine overclaims rather than adding unsupported new claims, and state supported claims directly rather than wrapping them in fresh hedges

• Global consistency — when renaming notation or changing a claim's scope, keep every restatement semantically consistent across ALL files (abstract, intro, method, experiments, theory sections, conclusion, tables, figure captions); consistency means matching scope, not copying disclaimer sentences everywhere

Typical Score Progression

Based on end-to-end testing on a real theory-paper run:

+4.5 points across 3 rounds (2 content + 1 format) is typical for a well-structured but rough first draft. Final state at submission: clean overfull-hbox count and venue-format-compliant length.
