BitFun AGENTS.md

Repository guidance for BitFun, a Rust workspace with React desktop interfaces and general-purpose AI-agent features.

In plain words
What is it for?
Use it when changing Rust code, React frontends, shared product logic, platform adapters, dependencies, or repository documentation.
Why use it?
It explains the project structure, where product logic belongs, how platform-specific adapters work, and which formatting and verification practices to follow.

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

BitFun 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 2d 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.

# AGENTS.md

BitFun is a Rust workspace plus React frontends.

Repository rule: **keep product logic platform-agnostic, then expose it through platform adapters**.

## Quick start

1. Read `README.md` and `CONTRIBUTING.md` before architecture-sensitive changes.
2. Use the primary product loop below for normal development. Surface-specific
   alternatives belong in the nearest app guide.
3. After Rust file changes, prefer `pnpm run fmt:rs` to format only changed or staged `.rs` files. Use `cargo fmt` only when you intentionally want broader formatting coverage.
4. After changes, use the nearest local `AGENTS.md` for the focused verification
   command. The repository-level verification section below only covers
   cross-cutting checks.
5. Workspace Rust dependencies own compatible versions, not broad capability
   unions. Each crate must select the dependency features it actually uses;
   keep test-only features in dev-dependencies and attach feature-gated service
   capabilities to the owning crate feature. Disable third-party defaults in
   `[workspace.dependencies]` when they are not part of every consumer's
   contract; members inherit that policy and add only their needed slices. For
   internal crates whose guarded `default` is empty, do not repeat
   `default-features = false` on every edge. Narrow consumers of an intentional
   compatibility default, such as ACP, must still disable it explicitly.
   Manifests copied into a standalone Docker build context must keep explicit
   versions and default policy because they cannot inherit the workspace root.
   `tokio/full` is forbidden in the root workspace and workspace members.

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.

BitFun AGENTS.md is an instructions file published in the GitHub repository GCWing/BitFun (1,871 stars, last pushed 2d ago), licensed MIT. It adds 5,169 tokens to every session, about $0.0258 per session on Opus 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.
