Fleur: Instructions file for Codex

AGENTS.md

Fleur AGENTS.md is an instructions file for Codex, OpenCode from WackyGem/Fleur. It costs 3,914 tokens per session, scanned A, original, MIT.

Project guidance for WackyGem/Fleur, a multi-part software project with Python data tools, Rust engines, a frontend, deployment files, and documentation. It describes the project layout and where key technical information is kept.

In plain words
What is it for?
Orienting work in the Fleur codebase, locating architecture and deployment documents, understanding the Python, Rust, and frontend areas, and following the project's documentation and workspace structure.
Why use it?
It gives coding agents a shared map of the repository so they can find the right component and follow its boundaries. It reduces confusion in a project made of several languages and subprojects.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Fleur 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 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.

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.
