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 | $0.02521 | $0.02521 |
| Opus 5.5 | $0.01008 | $0.01008 |
| Sonnet 5.5 | $0.00504 | $0.00504 |
| Haiku 4.5 | $0.00252 | $0.00252 |
Grade B, and why
odin-claude-plugin AGENTS.md scanned grade B 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 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
Edit both carriers in place. Never commit them from this repository, and never stage `~/.codex/config.toml`; their owning repositories live outside this submodule. How it starts
The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository contract
Repository file
Edit AGENTS.md, never CLAUDE.md. CLAUDE.md is a symlink, so replacing it forks the two files.
Canonical baseline
Make every persona or doctrine change in system-prompt-baseline.md; it is the only source of truth. The Claude Code loader resolves no references, so each of the six output styles under plugins/odin-core/output-styles/ embeds the full baseline as its tail, byte-identical from its second <role> through EOF. The generator owns that tail; never hand-propagate it:
- Edit
system-prompt-baseline.mdwithout changing an output style below its charter<role>. - Run
python3 scripts/sync-baseline.py. It replaces each style from its second<role>through EOF and preserves the persona preamble above it. - Run
python3 scripts/sync-baseline.py --check. Exit 0 means all styles match; exit 1 names drifted files; exit 2 means the canonical file or a required two-<role>layout is missing. - Stage and commit the canonical file and all six styles together.
Never hand-edit plugins/odin-core/output-styles/benchmark.md. Its margin-runner v0.5.5 header marks it as generated. The baseline generator may change only the embedded cascade below the runner preamble; a hand edit above that region requires explicit user authorization.
Submodule publishing
Commit and push from this repository, not its parent ~/.claude, because this tree is a Git
submodule. This checkout's .git is an unwritable submodule pointer, so git operations must run
in a clone inside .outline/worktree/<name>, never in /tmp, where work is easily lost.
Never force-push, and that includes every --force-with-lease variant: a lease protects the
remote from a stale overwrite and protects nothing from a rewrite you intended. On a branch with
an open pull request, rewriting history strands every inline review comment on commits that no
longer exist, and no permission error tells you that.
If a push is rejected as non-fast-forward, the answer is to fetch and rebase or to ask, never to reach for a force variant.
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.

odin-claude-plugin AGENTS.md is an instructions file published in the GitHub repository OutlineDriven/odin-claude-plugin (40 stars, last pushed 29d ago), licensed Apache-2.0. It adds 2,521 tokens to every session, about $0.0101 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
