cmos dev ee0bcd107e formatter: skip temperature override for reasoning models
GPT-5 and the o-series reject temperature=0 with a 400 BadRequestError —
only the default (1) is supported for reasoning models. Add an
_is_reasoning_model helper and pass temperature only when the model name
does not start with gpt-5/o1/o3/o4. Determinism on reasoning models is a
property of the architecture, not a parameter.

Discovered on the first real LLM run against the seed exemplars.

cmos — Chicago Manual of Style 18 bibliography reformatter

A Python tool that reformats the bibliography section of an English-language markdown draft to CMOS 18th edition, notes-and-bibliography form.

Accuracy-first, iterative, built with a karpathy/autoresearch-style dev loop.

See program.md for the goal specification and /home/claudecode1/.claude/plans/pure-mixing-yao.md for the implementation plan.

Quick start

uv sync
uv run pytest
uv run cmos format path/to/draft.md > out.md

Layout

  • src/cmos/formatter.py — the iterable artifact (edited every loop iteration).
  • src/cmos/parser.py — extracts the bibliography section from a draft.
  • src/cmos/linter.py — deterministic CMOS 18 rule checks (versioned).
  • src/cmos/cli.pycmos format entry point.
  • harness/score.py, harness/diff.py — frozen scoring.
  • exemplars/ — TOML test corpus.
  • tests/ — pytest suite (linter, parser, formatter, cli).
  • rough_drafts/ — user-supplied messy drafts for ad-hoc iteration.
  • logs/ — per-run scores, model ids, linter version hashes.
