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 | $0.00400 | $0.00400 |
| Opus 5.5 | $0.00160 | $0.00160 |
| Sonnet 5.5 | $0.00080 | $0.00080 |
| Haiku 4.5 | $0.00040 | $0.00040 |
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 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.

Nix symlinks — when to rebuild
Almost every file under config/ (shell, editors, macos, git, agents) is symlinked into place by home-manager with mkOutOfStoreSymlink (see config/nix/system/symlinks.nix). Editing those files takes effect immediately — never suggest running rebuild after editing them.
rebuild is only needed when config/nix/ itself changes:
packages/*.nix— packages added or removedsystem/symlinks.nix— symlink entries added, removed, or repointedsystem/macos-defaults.nix,flake.nix
Special cases:
karabiner.edn→ rungoku(never editkarabiner.json)config/agents/global_skills/→ each skill directory is linked one by one into~/.claude/skillsand~/.agents/skills, so adding or removing a skill needsgit add+rebuild; editing an existing skill does not- Shell config (aliases, functions, zshrc) → only affects new shell sessions
Git
- If you think it makes sense to split something into separate commits, go ahead and do it.
- Do not autocommit
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.
