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 | $0.04176 | $0.04176 |
| Opus 5 | $0.02088 | $0.02088 |
| Sonnet 5 | $0.00835 | $0.00835 |
| Haiku 4.5 | $0.00418 | $0.00418 |
Grade A, and why
flight-finder CLAUDE.md scanned grade A with 1 finding 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 9d 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.

Monorepo
npm workspaces: @flight-finder/web (apps/web/), @flight-finder/cli (packages/cli/).
Root package.json proxies common scripts to @flight-finder/web. apps/desktop/ is a Tauri (Rust) launcher: deliberately NOT an npm workspace member and excluded from npm run ci; it is built only by .github/workflows/desktop-release.yml.
The CLI bundles the shared scraper (apps/web/src/lib/scraper/*) via relative imports but maps @/* to its own packages/cli/src/, so any new @/lib/<x> import added to a shared scraper file needs a matching shim in packages/cli/src/lib/ (re-export the real module like secret-crypto.ts/prisma.ts, or a stub like admin-recovery.ts). Web-only checks pass without it; only the full npm run ci (web + cli) catches a missing shim.
Versioning (locked): apps/web, the root package.json, packages/cli, and apps/desktop all carry the SAME version number. apps/web/package.json is the source of truth; git tags vX.Y.Z track the web release and desktop-vX.Y.Z tags the desktop build at the same number (distinct prefixes, no collision). /create-release must bump all of them to the new version — apps/web/package.json, root package.json, packages/cli/package.json, and apps/desktop (its package.json, src-tauri/Cargo.toml, and src-tauri/tauri.conf.json) — and regenerate both lockfiles (package-lock.json and apps/desktop/src-tauri/Cargo.lock).
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.

flight-finder CLAUDE.md is an instructions file published in the GitHub repository affromero/flight-finder (147 stars, last pushed yesterday), licensed MIT. It adds 4,176 tokens to every session, about $0.0209 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
