MongoDBAGENTS.md

kingfisher

mongodb/kingfisher/docs/AGENTS.md

Guidance for editing documentation under docs/. - State backward compatibility explicitly when documenting rule/schema changes: existing Kingfisher YAML and Betterleaks TOML rules must work without edits. New HTTP fallback execution uses --fallbacks; both primary-reuse booleans default to false. Reusing validation does not imply revocation reuse. Explain explicit revocation URL replacement and no mutation failover. - Document CLI revoke --fallbacks as validate-to-select followed by one action, without manual VALIDATION_* variables. Distinguish SDK snapshot-based revocation and unchanged direct-primary defaults.

kingfisher / benchmark

mongodb/kingfisher/docs/benchmark/AGENTS.md

Applies to this directory, including main.go, generated reports, and README.md. - Keep main.go as the only Go source file in this directory. It contains the executable benchmark harness and chart generation. Do not add a separate main_test.go or alternate Go implementation. - Build from this directory with go build -o benchmark main.go, and run the resulting executable with the required benchmark options. Check compilation and use targeted benchmark runs to validate changes. - Use a detection-only run of Kingfisher, TruffleHog,…

kingfisher / javascript

mongodb/kingfisher/javascript/AGENTS.md

Guidance for extending and maintaining the JavaScript/TypeScript SDK. - Applies to javascript/. Follow the repository guidance and consult this guide for Node-facing changes in the Node-API bridge or shared Rust crates; those crates retain their own applicable instructions. - The npm package is kingfisher-secret-scanner. It calls the shared kingfisher-core, kingfisher-rules, and kingfisher-scanner crates in process through napi-rs/Node-API, not through Python or a CLI subprocess. - Keep the pipeline composable: Rule loading configures these stages. Revocation is a separate, explicitly authorized…

Guidance for extending and maintaining the Python SDK. - Applies to python/, including the public package, tests, and examples. Follow the repository guidance and any deeper instructions as well. - The native bindings guidance incorporates these principles for the Rust bridge. Consult this guide when shared Rust changes affect Python behavior; shared crates retain their own instructions. - Keep the SDK composable, predictable, and suitable for embedding. Users should be able to supply their own inputs and choose capabilities independently.…

Instructions for AI coding agents working in this repository. This file is the source of truth; tool-specific files (e.g. CLAUDE.md) should only import it. bson is the BSON codec library for JavaScript (Node.js and browser), implementing the BSON specification. It provides BSON type classes, serialization/deserialization to and from BSON bytes, and Extended JSON (EJSON) support. It is the codec used by the node-mongodb-native driver, and also a standalone library external users depend on. All benchmark runs first measure a CPU…

Before changing code, read and follow CONTRIBUTING.md and SECURITY.md. In particular: - Project structure, generated and handwritten code, and repository layout: package ownership, dependency direction, command compatibility, assembly order, safe help recovery, and the separate api_reference/go.mod module. Reuse existing packages; explain any new package's distinct responsibility. - Security requirements: credential handling, synthetic tests, diagnostic redaction, dependency/install review, the existing hourly SDK updater, workflow permissions, signing/publication boundaries, and required SDK CODEOWNER review.

CLAUDE.md vs AGENTS.md

About AGENTS.md

What is AGENTS.md?

An open format for instructions to coding agents, read by Codex, Cursor and others. Think of it as a README written for agents.

Where does it go?

At the repository root, with more specific files in subdirectories. Agents read the one closest to the file they're editing.

What should it contain?

Setup and test commands, code style, and the rules a new contributor would need to know.

Does Claude Code read it?

Claude Code reads CLAUDE.md. A one-line CLAUDE.md that points at AGENTS.md covers both.
