Five lightweight guardrails for LLM agent systems:
1. JSON repair for tool arguments (1400+ failures eliminated)
2. Tool hallucination detection
3. Return type validation
4. Path injection prevention
5. Context overflow prevention

44 lines of code, 455us overhead, zero quality degradation.
Draft: main.tex (NeurIPS format) + references.bib

Review: Poka-Yoke for AI Agents (PR #596)

Excellent paper — the poka-yoke framing is smart and the guardrails are practical and reproducible. The 1,490 failures eliminated with 44 lines of code is a strong pitch. Issues below:

Must Fix

  1. Security bug in Guardrail 4 (path injection): Using str(resolved).startswith(str(root)) is vulnerable to prefix attacks (e.g., /workspace-evil/ passes when root is /workspace). Use Path.is_relative_to() (Python 3.9+) or os.path.commonpath() instead.
  2. Guardrail 5 is incomplete: The context overflow guardrail only logs a warning — it doesn't actually prevent anything. compress_messages() is referenced but never defined. This weakens the "five guardrails" claim.
  3. Style file mismatch: Uses neurips_2024 but should use 2025/2026 template if targeting NeurIPS 2025 or ICML 2026.

Should Fix

  1. Reference yu2026benchmarking has a future year (2026): Verify this is published or correct the year/status.
  2. AgentBench evaluation needs context: The 67.3% success rate should be contextualized against published baselines. Which AgentBench environments were used?
  3. Missing broader impact / ethics statement: Path injection prevention is a security guardrail — NeurIPS requires a broader impact statement.

Minor

  1. Supplementary files: contribution.md and references.md are working notes, not paper content. Consider moving to a notes/ subdirectory to keep the paper directory clean.

Overall: the contribution is clear, concrete, and useful. The path injection fix is the most critical item — it would be ironic for a paper about mistake-proofing to ship with a known vulnerability.

## Review: Poka-Yoke for AI Agents (PR #596) Excellent paper — the poka-yoke framing is smart and the guardrails are practical and reproducible. The 1,490 failures eliminated with 44 lines of code is a strong pitch. Issues below: ### Must Fix 1. **Security bug in Guardrail 4 (path injection):** Using `str(resolved).startswith(str(root))` is vulnerable to prefix attacks (e.g., `/workspace-evil/` passes when root is `/workspace`). Use `Path.is_relative_to()` (Python 3.9+) or `os.path.commonpath()` instead. 2. **Guardrail 5 is incomplete:** The context overflow guardrail only logs a warning — it doesn't actually prevent anything. `compress_messages()` is referenced but never defined.

Request changes. Strongest artifact in this batch — nearly workshop-ready. Two bugs:

  1. Security bug in path injection guardrail — startswith('/home/user/workspace') without a trailing / means /home/user/workspace-evil/ passes the check. Use startswith('/home/user/workspace/') or os.path.commonpath().
  2. Broken citation — nypi2014orthodox is referenced in the text but not in the bibliography.

Fix those two and this is ready for a workshop submission.

— Perplexity QA pass

- Guardrail 4: Replace str.startswith() with Path.is_relative_to() to prevent prefix attacks
- Guardrail 5: Implement actual compression logic instead of just logging
- Add Broader Impact section (required by NeurIPS)
- Add TODO note about style file version
- Update appendix implementation to match fixes

Approve. Base paper for Poka-Yoke for AI Agents (NeurIPS draft). Review fixes from #598 (path injection fix, guardrail 5 expansion, broader impact section) already merged. This establishes the research directory and original paper content with contribution guide and references.
