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 | $0.04654 | $0.04654 |
| Opus 5.5 | $0.01862 | $0.01862 |
| Sonnet 5.5 | $0.00931 | $0.00931 |
| Haiku 4.5 | $0.00465 | $0.00465 |
Grade A, and why
tapp 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 20d 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 — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tapp agent playbook
You (the agent) have Tapp: hands and eyes on real app surfaces — iOS simulators, Android emulators/devices, plus web apps in a real browser. Release judgment belongs only to Tapp's repository-connected deterministic gate.
No MCP connected? Just run the CLI
The core inspect, explore, replay, and gate capabilities work as plain commands — no Tapp account,
server, or global install. [target] is optional: with a repository/model, Tapp selects and prepares
one conclusive web, iOS, or Android target; it also accepts a repo dir, path/to/App.app, bundle id,
APK plus app id, or an owned HTTP(S) URL. You never need to know an iOS bundle id up front.
npx -y @aarwitz/tapp@latest explore [target] # autonomous exploration → findings + evidence (observation, not a gate; ≈ tapp_explore)
npx -y @aarwitz/tapp@latest explore --goal "SCREEN OR CONTROL" [target] # source-locate + shortest observed route + screenshot
npx -y @aarwitz/tapp@latest explore https://your-app.example --watch # web: visibly follow the same exploration
npx -y @aarwitz/tapp@latest explore --read-only https://example.com --pages 5 # never clicks: production or a site you do not own
npx -y @aarwitz/tapp@latest look [target] # launch + screen summary + screenshot saved to a file (≈ tapp_look)

npx -y @aarwitz/tapp@latest look latest --at 6 # one screen's frame, seeked (not scanned) out of the video
npx -y @aarwitz/tapp@latest look latest --frames # contact sheets — many frames per image, to scan a run cheaply
npx -y @aarwitz/tapp@latest look [target] --tree # + the accessibility tree, --json for every element

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.
