beanz AGENTS.md

A contributor guide for beanz, a Rust and Cargo project that scores cognitive debt in AI coding sessions. It sets rules for development workflow, communication, naming, public interfaces, and abstractions.

In plain words
What is it for?
It guides developers through checking, testing, and building the Rust project, following its naming and API conventions, reporting new dependencies, and handing off changes without committing unless asked.
Why use it?
It keeps changes focused and makes expectations clear for testing, third-party dependencies, commits, and uncertainty. This helps contributors avoid unrelated refactoring and unreviewed project changes.

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

beanz 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.

General programming workflows

  • beanz is a Rust-only Cargo project (cognitive debt scoring for AI coding sessions). Use idiomatic Rust unless stated otherwise.
  • No drive-by refactors or unrelated files; no new markdown/docs unless the user asks (e.g. READMEs).
  • Use cargo check for fast feedback during iteration; run cargo test (and cargo build --release when relevant) before considering work done.
  • Always report to the developer if you are adding any new third-party crates.
  • Never stray away from the plan set out by the developer.
  • Function as an informative AI coding agent to assist the developer with features, bugs, test coverage, and architecture.
  • Stay within the bounds of the task set out to you.
  • If you are not confident in your answers, say so — honesty is critical.
  • Do not commit unless the developer explicitly asks. Ask first before creating a commit; leave changes for the developer to review and commit when they have not asked.

AI communication

  • Keep replies concise and consistent in tone and structure.
  • Be clear; ask direct questions when something is ambiguous. Do not waffle, hedge with filler, or pad with generic advice.
  • If you are not sure of an answer, say so plainly and work with the developer to close the knowledge gap (what you need checked, what options depend on unknowns, what to read or run next).

Naming conventions (strict)

  • Do not use the words mock, manager, integration test, utility, helper, or sink as substrings in beanz-authored identifiers or API symbols, or in string literals you choose (e.g. not SessionManager, build_helper). Applies to types, functions, methods, fields, locals, modules, and exposed config keys. Prefer neutral names such as setup_*, build_*, with_*, prepare_*.
  • This applies to the entire codebase, not only pub items.

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.
