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 | $0.02063 | $0.02063 |
| Opus 5.5 | $0.00825 | $0.00825 |
| Sonnet 5.5 | $0.00413 | $0.00413 |
| Haiku 4.5 | $0.00206 | $0.00206 |
Grade A, and why
crewplane 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 today.
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 — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Canonical repository instructions for coding agents.
Use this file for repo-wide agent behavior. Use DEVELOPMENT.md for broader engineering context and maintenance notes. More specific AGENTS.md files in subdirectories override this file for their subtree.
Repo Facts
crewplane is a Python 3.13+ Typer CLI for running multi-agent workflows defined in Markdown. The core architectural rule is blackboard-style orchestration: providers do not coordinate through shared in-memory state; they communicate through artifacts written under .crewplane/.
Crewplane supports Linux, macOS, and WSL. Native Windows acceptance is pending. Preserve the scope and lifecycle guarantees in ADR 0018, and require its acceptance evidence before advertising support.
When changing behavior, preserve these properties:
- CLI-first provider integration. The project is built around external AI CLIs, not vendor SDKs.
- Auditable execution. Inputs, intermediate outputs, manifests, and results stay on disk as readable files.
- Explicit boundaries. Config loading, workflow parsing/composition, adapter resolution, provider invocation, runtime execution, artifacts, and observability are separated on purpose.
- Deterministic validation. New behavior should be covered by filesystem-local pytest tests, and mock-driven end-to-end checks should stay available.
Task References
Consult documentation relevant to the task:
- Test guidance: required when creating, changing, or reviewing
tests, fixtures, test helpers, or test automation, including under
scripts/ - README.md: product orientation
- DEVELOPMENT.md: setup, validation, release, and maintenance procedures
- Module and test map: implementation entry points and affected tests
- Public documentation: documented user behavior
- Architecture: boundaries, lifecycle contracts, and ADRs
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.

crewplane AGENTS.md is an instructions file published in the GitHub repository crewplaneai/crewplane (44 stars, last pushed today), licensed Apache-2.0. It adds 2,063 tokens to every session, about $0.0083 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.
