Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00721 | $0.00721 |
| Opus 5.5 | $0.00288 | $0.00288 |
| Sonnet 5.5 | $0.00144 | $0.00144 |
| Haiku 4.5 | $0.00072 | $0.00072 |
Grade A, and why
codex-profiles AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository guidance
Read CONTRIBUTING.md and docs/compatibility.md before changing behavior. Check current issues and pull requests before starting nontrivial work, and agree on feature scope through an issue or discussion. Keep changes focused and update documentation and regression tests when behavior changes.
Keep current project status and outstanding decisions in docs/next-version.md. Update that record when work ships or scope is agreed; separate current status from dated historical research.
Supported behavior
Codex Profiles manages file-backed account credentials. Preserve CODEX_HOME
resolution, existing saved profiles, and refusals for unsupported credential
stores and authentication modes. --force must not bypass those refusals.
Account profiles are distinct from native Codex configuration profiles. Save/load currently handles authentication only. Optional config snapshots are a design proposal; unresolved design choices are not implemented behavior. Keep encrypted-export design separate from snapshot storage and restoration.
Before changing credential handling, refresh, configuration lookup, or usage
parsing, check current official OpenAI documentation and relevant openai/codex
source. Internal types alone do not establish a supported app-server method.
Record reviewed revisions and limits in docs/compatibility.md. Advance
.github/codex-compatibility.json only after reviewing upstream changes.
Validation and privacy
Use synthetic credentials, temporary Codex homes, and loopback servers in tests. Never use live accounts or real auth files in automated checks. Keep real credentials, private paths, personal contact details, and session history out of fixtures, logs, commits, and reports. Use portable paths and clearly synthetic examples in public documentation. Bound concurrency-test waits and control request timing explicitly.
Use the pinned Rust toolchain and run make precommit. For automation changes,
also run python3 -B scripts/test-automation.py and relevant script tests.
Coverage has no minimum percentage; preserve meaningful real-I/O and concurrency
tests and do not exclude production code to improve the metric.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-profiles AGENTS.md is an instructions file published in the GitHub repository midhunmonachan/codex-profiles (94 stars, last pushed 4d ago), licensed MIT. It adds 721 tokens to every session, about $0.0029 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-27.
