Making a Repository Agent-Ready

A practical guide to configuring any repository so that AI agents can operate effectively within it.

#What Agent-Ready Means

An agent-ready repository is one where an AI agent can enter, understand the project, and execute meaningful tasks with minimal human guidance. This is not about a single file or tool — it's a structural property of the entire project.

#The Entry Point: AGENTS.md

The most critical file. When an agent enters a repository, this is the first thing it reads. Name it AGENTS.md and symlink it as CLAUDE.md, .cursorrules, and .windsurfrules so every major agent tool finds it automatically. It should contain:

1. Project purpose — one paragraph on what this project does and why
2. Architecture map — directory layout with what each folder contains
3. Build and test commands — exact commands to build, test, and run
4. Conventions — commit message format, code style, naming patterns
5. Pointers — where to find specs, skills, rules, and other context

Keep it under 200 lines. Every line competes for context window space.

#Directory Structure

Agent-friendly structure follows these principles:

• Predictable layout: Agents navigate by convention. Standard directories (src/, tests/, docs/) reduce exploration overhead
• Self-describing names: A directory named specs/ is immediately understood; misc/ is not
• Flat over deep: Shallow hierarchies are easier to scan and reference
• Co-located context: Keep related files together (tests next to source, translations next to originals)

#Atomic Commits

Agents work best with atomic, well-labeled commits:

• Each commit does one thing
• Commit messages use consistent prefixes (feat:, fix:, refactor:, docs:)
• The commit message explains why, not just what
• This makes git log and git blame useful context sources for agents

#SPEC-Driven Decisions

For non-trivial decisions, write a spec before implementing:

• Specs capture the reasoning behind architectural choices
• Agents can read specs to understand constraints without re-deriving them
• Specs prevent agents from unknowingly reversing deliberate decisions

#Configuration: .claude/settings.json

Project-level agent configuration reduces friction:

• Permission allowlists for common operations (build, test, git)
• Hook definitions for automated checks
• Environment-specific overrides via .claude/settings.local.json

#Failure Journal

Maintain a record of agent failures and their resolutions:

• What went wrong and why
• What was changed to prevent recurrence
• This enables agent self-evolution across sessions
