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 | $0.01611 | $0.01611 |
| Opus 5.5 | $0.00644 | $0.00644 |
| Sonnet 5.5 | $0.00322 | $0.00322 |
| Haiku 4.5 | $0.00161 | $0.00161 |
Grade A, and why
clawker 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clawker
Clawker is a Go CLI that runs coding agents in Docker containers with controlled access to host resources.
Shared instructions
Claude Code and Codex must use the same project instructions, skills, and memories.
Store instructions in regular AGENTS.md files. Each must have a sibling CLAUDE.md symbolic link with the relative target AGENTS.md.
Before reading or changing files, read the Serena core memory and the memories it names for the touched domain.
Read package AGENTS.md files along the path to each file, including files outside the working directory. Requirements for one package tree live in that tree's AGENTS.md.
Use instructions already loaded in the session. Do not load an entire reference directory.
Keep .agents/ independent of any harness. Store native settings and tool-specific hooks in .claude/ or .codex/. A skill that is also a subagent keeps each harness definition in its agents/ directory.
Work rules
- State assumptions. Present different interpretations and ask when the choice is unclear.
- Define a verifiable result before coding. For work with multiple steps, state a short plan and its checks.
- This is an alpha project. Correct design defects and technical debt before continuing affected work.
- Consider architecture, tests, documentation, and effects on users and developers. Use a simpler design when possible.
- Follow the Serena
designandarchitecturememories; update them when the design changes. - Write tests before production code. Add missing interfaces, mocks, fakes, and test subpackages as required. All applicable tests must pass.
- Update the README, affected
AGENTS.mdfiles, documentation, and shared memories after changes. - When both agents work at the same time, preserve the other agent's edits and check the current diff before writing shared files.
- Use ASD-STE100 Simplified Technical English and its current approved dictionary for chat, documentation, and code comments. Replace unapproved words unless they are standard technical names. Apply the standard; do not restate 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.

clawker AGENTS.md is an instructions file published in the GitHub repository schmitthub/clawker (58 stars, last pushed today), licensed MIT. It adds 1,611 tokens to every session, about $0.0064 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 2026-08-30.
