# Agent Configuration Specification v1.0 > Defines what "well-configured" means for AI agent development across all coding projects. ## CLAUDE.md — Required Sections ### Tier 1 (Required — blocks audit pass) 1. **Conditional Documentation Loading** — Table linking to `~/.config/mosaic/guides/` 2. **Quality Gates** — Bash commands that must pass before commit (build, test, lint, typecheck) 3. **Build/Test/Lint commands** — How to build, test, and lint the project ### Tier 2 (Recommended — logged as warning) 4. Technology Stack table 5. Repository Structure tree 6. Commit format reference 7. Secrets management note 8. Multi-agent coordination note 9. **Campsite Rule** — "Touching it makes it yours" policy for code violations ### Tier 3 (Optional — nice to have) 10. Code Review section (Codex commands) 11. Issue Tracking workflow 12. Session Protocol (start/end) ## AGENTS.md — Required Sections ### Tier 1 (Required) 1. **Codebase Patterns** — At least one entry or placeholder with instructive comments 2. **Common Gotchas** — At least one entry or placeholder with instructive comments 3. **Quality Gates** — Duplicated for quick agent reference ### Tier 2 (Recommended) 4. Key Files table 5. Testing Approaches section ## Monorepo Sub-AGENTS.md Required in any directory under `apps/`, `packages/`, `services/`, or `plugins/` that contains its own `package.json` or `pyproject.toml`. Minimum content: 1. Purpose (one line) 2. Patterns (at least placeholder) 3. Gotchas (at least placeholder) ## Detection Markers The `agent-lint.sh` tool checks for these markers: | Check | Pass Criteria | |-------|---------------| | CLAUDE.md exists | File present at project root | | AGENTS.md exists | File present at project root | | Conditional context/loading | CLAUDE.md contains `~/.config/mosaic/guides` or `Conditional` + `Loading/Context` | | Quality gates | CLAUDE.md contains `Quality Gates` or quality commands (test, lint, typecheck) | | Monorepo sub-agents | Each app/package dir with own manifest has AGENTS.md | ## Fragment Sources Shared sections are maintained in `~/.config/mosaic/templates/agent/fragments/`: | Fragment | Injects Section | |----------|----------------| | `conditional-loading.md` | Conditional Documentation Loading table | | `commit-format.md` | Commit format convention | | `secrets.md` | Secrets management note | | `multi-agent.md` | Multi-agent coordination protocol | | `code-review.md` | Code review commands | | `campsite-rule.md` | Campsite Rule — fix violations you touch |
