Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01559 | $0.01559 |
| Opus 5 | $0.00779 | $0.00779 |
| Sonnet 5 | $0.00312 | $0.00312 |
| Haiku 4.5 | $0.00156 | $0.00156 |
Grade A, and why
codex-auth-switcher 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 yesterday.
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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository development guide
Purpose
This file contains repository-specific rules for humans and automated coding agents.
Follow the global engineering guide for general planning, Git safety, scope control, test-first development, verification, and reporting.

Do not add model routing, personal settings, or other machine-specific configuration to this repository guide.
Project map
codex-switch is an unofficial Go CLI for managing local OpenAI Codex CLI
authentication profiles.
cmd/codex-switch/— CLI entry point.internal/app/— command dispatch, orchestration, and user-visible output.internal/auth/— extraction of non-secret account identity metadata.internal/store/— profile storage, atomic writes, switching, rollback, cleanup, and filesystem permissions.internal/usage/— livecodex app-serverusage capture and normalization..github/workflows/ci.yml— authoritative CI validation sequence.
Correctness, rollback behavior, filesystem permissions, and secret-safe output take priority over convenience.
Security boundaries
Read SECURITY.md before changing authentication, profile storage, switching,
cleanup, permissions, or account-related output.
Never print, commit, attach, or retain as evidence:
auth.jsonor its raw contents;- JWTs or OAuth tokens;
- access, refresh, or bearer tokens;
- contents of
~/.codex-auth-switcher; - Codex session logs;
- unredacted account identifiers;
- terminal output or screenshots containing authentication data.
Tests and routine validation must never read or mutate the developer's real Codex state.
Do not run these commands against the default user environment as routine validation:
codex-switch add;codex-switch use;codex-switch rename;codex-switch delete;codex-switch capture;codex-switch prepare-login;codex-switch cleanup --apply;- equivalent mutating commands through
go run; make install;- Codex login or logout flows.
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-auth-switcher AGENTS.md is an instructions file published in the GitHub repository curserio/codex-auth-switcher (1 stars, last pushed 27d ago), licensed MIT. It adds 1,559 tokens to every session, about $0.0078 per session on Opus 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 2026-08-31.
