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 | $0.02657 | $0.02657 |
| Opus 5.5 | $0.01063 | $0.01063 |
| Sonnet 5.5 | $0.00531 | $0.00531 |
| Haiku 4.5 | $0.00266 | $0.00266 |
Grade A, and why
dotfiles 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 2mo 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md (Project)
This is fmind/dotfiles — a chezmoi + mise dotfiles repo for AI-CLI-first development on Linux and Mac OS with Go and Python as the core programming languages.
User-facing install and usage docs live in README.md; this file is for agents working inside the repo.
House rules
- Chezmoi Force: Always use
chezmoi apply --forcein scripts/automation to prevent interactive prompt blocks. - Edit-source: Change files in chezmoi source (
~/.local/share/chezmoi/...), never deployed copies under~/.geminior~/.config. - GitHub Access: Use
ghCLI for repository, issue, and PR operations. - Git Push to Main: Direct commit/push to
mainbranch is permitted (no feature branch required). - Lint-before-done:
mise run all(format + check + test + build, the same gate CI runs) must pass before reporting a task complete. - Markdown Lists: Only use
1.for all numbered list items in markdown files to ensure correct dynamic rendering. - No-Hard-Wrap: Every
*.mdkeeps each paragraph on a single line. - No-Sudo: Stay user-space; install via
mise. - README Scope: Keep setup/auth instructions in
README.md; exclude repository tasks, aliases, and workflows. - Secrets:
*.agefiles are encrypted; never modify or commit decrypted versions. - Theme: Tokyo Night (Moon) is default across every tool that supports theming.
- Vim mode: Enable in every TUI that supports it.

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.
