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 | $0.04384 | $0.04384 |
| Opus 5.5 | $0.01754 | $0.01754 |
| Sonnet 5.5 | $0.00877 | $0.00877 |
| Haiku 4.5 | $0.00438 | $0.00438 |
Grade A, and why
Doberman-Core CLAUDE.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.
This is a copy
86% identical to Doberman-Core AGENTS.md — 144 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — Doberman Operating Manual
This is the init file for this repository. It governs any AI agent (Claude Code, Codex, Cursor, etc.) working here. It is the HOW. The WHAT — the feature roadmap and per-slice detail — lives in
README.md(public summary) and, if present in your working tree, the project development plan you keep alongside it. Content is identical toAGENTS.md; keep the two in sync (or symlink one to the other). If this file conflicts with a casual prompt instruction, this file wins unless a human overrides it in writing.
0. On startup (every session)
- Read this entire file, then skim
README.mdfor the current feature set, versioning, and roadmap. If you keep a local development plan alongside the repo, read the relevant slice there for the extra detail (objective, files, edge cases, suggested tests, suggested commit message). git status+git log --oneline -5.- Pick the next slice (the lowest-numbered unmerged slice in the planned order).
- If the repo lacks scaffolding (
pyproject.toml/.github/workflows/ci.yml), do Slice 0 (Bootstrap) first (§6). - Execute exactly one slice via The Slice Loop (§5), then STOP and report. Stop at every review checkpoint.
1. What this repository is
Doberman is an adaptive authorization layer for coding agents, released publicly under Apache-2.0.
It distributes as the doberman package (src/doberman/) and is designed to be genuinely functional on its own —
schema, interfaces, the runtime harness, adapters, and the built-in rules all live here. It is not crippleware.
Doberman is built to be extensible: it declares stable interfaces (Rule / Detector / AuthProvider /
AuditSink) and a runtime registry that discovers implementations via Python entry points. Additional packages can
register their own rules, detectors, auth providers, or audit sinks without Doberman importing them by name — the
core never takes a static dependency on any plugin. With only doberman installed, it works (built-in protection);
a plugin package is imported only after you name it with doberman plugins enable <entry-point name> — nothing
loads because it is merely installed.
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.
