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 | $0.00611 | $0.00611 |
| Opus 5.5 | $0.00244 | $0.00244 |
| Sonnet 5.5 | $0.00122 | $0.00122 |
| Haiku 4.5 | $0.00061 | $0.00061 |
Grade A, and why
codex-trace 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

Commands
# Dev
npm run dev # Vite dev server
npm run tauri dev # Full Tauri desktop app
npm run dev:web # Web mode (opens browser)
# Lint
npx oxlint # JS/TS lint
cargo clippy --manifest-path src-tauri/Cargo.toml # Rust lint
# Format
npx oxfmt # JS/TS format
cargo fmt --manifest-path src-tauri/Cargo.toml # Rust format

# All at once
npm run check # tsc + oxlint + oxfmt --check + clippy + cargo fmt --check + vitest + cargo test
Rule
After every code change (src, tests, config that affects build), always add enough tests for the changes, then run lint, format, and test before committing:
npx oxfmt && npx oxlint && npx tsc --noEmit && cargo fmt --manifest-path src-tauri/Cargo.toml && cargo clippy --manifest-path src-tauri/Cargo.toml -- -D warnings && cargo test --manifest-path src-tauri/Cargo.toml
Architecture
- Backend: Rust + Tauri v2 + axum HTTP server (port 11424)
- Frontend: React 19 + TypeScript + Vite
- Sessions:
~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl

JSONL format
Three session_meta variants (new/mid/oldest). Turn boundary detection uses
task_started/task_complete for newer CLI; user_message boundaries for older.
Tool calls classified by end event type, not function name.
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-trace AGENTS.md is an instructions file published in the GitHub repository PixelPaw-Labs/codex-trace (116 stars, last pushed 6d ago), licensed MIT. It adds 611 tokens to every session, about $0.0024 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 2026-08-30.
