agents-md

Author and maintain AGENTS.md files — the open, tool-agnostic format for giving coding agents project context. Use when: creating AGENTS.md; writing an agent instructions file; root or nested AGENTS.md for monorepos; migrating CLAUDE.md, AGENT.md, .cursor/rules, or copilot-instructions.md to AGENTS.md; greenfield project setup before code exists; brownfield onboarding for an existing codebase; documenting build/test/lint commands, code style, PR/commit conventions, and security considerations for agents; AGENTS.md discovery and precedence rules. Works for any language, framework, or project size. DO NOT USE FOR: authoring SKILL.md skill files (use create-skill); APM package/plugin authoring (use apm-producer); language-specific style rules (use language skills e.g. csharp-best-practices).

AGENTS.md

A README for agents: plain Markdown, no required fields, read by 20+ coding agents (Codex, Cursor, Copilot, Aider, Gemini CLI, Windsurf, Devin, and more).

Quick Facts

Fact	Detail
Location	`AGENTS.md` at repo root; additional copies nested per package/subproject
Discovery	Agent reads the nearest `AGENTS.md` up the directory tree from the file it's editing
Precedence	Closest file to the edited file wins; explicit chat/user instructions override everything
Format	Standard Markdown, any headings, no schema to validate
Execution	Agents run commands listed in it (tests, lint) and try to fix failures before finishing

Workflow Picker

flowchart TD
    A[Writing AGENTS.md] --> B{Code, CI, or docs already exist?}
    B -- No --> C[Greenfield workflow]
    B -- Yes --> D[Brownfield workflow]
    C --> E{≥2 packages?}
    D --> E
    E -- Yes --> F[Nest AGENTS.md per package]
    E -- No --> G[Single root AGENTS.md]

Situation	Use
No code yet / scaffolding a new repo	Greenfield workflow
Existing codebase, README/CI/CLAUDE.md already exist	Brownfield workflow
Monorepo with multiple packages	Nesting rules
Migrating from AGENT.md, CLAUDE.md, `.cursor/rules`, `copilot-instructions.md`	Legacy migration

Core Principle

Never hardcode language, framework, or tool assumptions into an AGENTS.md — every instruction must reflect the target repo's actual, verified stack and commands, not a generic template left unfilled.

AGENTS.md is still a Markdown file: run markdown-best-practices over the draft before treating it as finished (heading spacing, table/list consistency, fenced-code language tags).

Reference Files

File	Load When
references/anatomy-and-discovery.md	Deciding where files live, how precedence works, or migrating from a legacy agent file
references/authoring-workflow.md	Writing a new AGENTS.md for a greenfield or brownfield project
references/writing-style.md	Wording and formatting an AGENTS.md section for density and scannability
references/quality-and-security.md	Reviewing content quality, verifying commands, or covering security considerations

3d-rotation-theory

無料

Abstract math for 3D rotation representations and conversions. USE FOR: understanding axis-angle representation; Euler angles (yaw/pitch/roll, convention choices); rotation matrices (SO(3)); quaternion-based rotation; converting between representations; identifying and avoiding gimbal lock; composing rotations; half-angle formula; right-hand rule. DO NOT USE FOR: quaternion arithmetic details (use quaternion-algebra); slerp/lerp interpolation (use interpolation-on-manifolds); coordinate system definitions (use coordinate-system-conversions).
