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 | $0.02422 | $0.02422 |
| Opus 5.5 | $0.00969 | $0.00969 |
| Sonnet 5.5 | $0.00484 | $0.00484 |
| Haiku 4.5 | $0.00242 | $0.00242 |
Grade A, and why
bitbottle 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 4d 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Context and delegation — highest priority
- Keep the main chat and its context lean. Delegate large file reads and data retrieval to dedicated subagents using smaller models; return concise findings with source paths and line numbers, never full content dumps.
- NEVER use the same agent to retrieve large content and make decisions, evaluations, judgments, or edits. Retrieval agents gather evidence only; the caller decides from their concise results.
- Assign actions to separate small subagents with explicit instructions, a bounded scope, and a clear completion check. They return the result, changed paths, and verification evidence.
- Pass each subagent only the context needed for its task. Reuse concise findings instead of reloading large sources into the main chat or action agents.
See CONTRIBUTING.md for full workflow, code style, and testing conventions.
Reference implementations
reference/gh/ contains a shallow clone of github.com/cli/cli. When in doubt about CLI design patterns (flag naming, config structs, auth flows), check how gh does it there first.
Design principles
Read before designing any new command, interface, package, transport, MCP tool, or error site. Pre-merge-check §6 ("Design-judge") gates merges against both.
docs/TASTE.md— UX (gh philosophy, standard flags, TTY-aware output, error format), agentic skill experience, MCP tool shape.docs/ARCHITECTURE.md— SOLID, layered structure, composite + optional interfaces, deep modules, design decisions, gh references.

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.

bitbottle AGENTS.md is an instructions file published in the GitHub repository proggarapsody/bitbottle (3 stars, last pushed 4d ago), licensed MIT. It adds 2,422 tokens to every session, about $0.0097 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 2026-08-31.
