AgentLens - Codebase Navigation

Before Working on Any Codebase

Always start by reading .agentlens/INDEX.md for the project map.

Navigation Hierarchy

| Level | File | Purpose | |-------|------|---------| | L0 | INDEX.md | Project overview, all modules listed | | L1 | modules/{slug}/MODULE.md | Module details, file list | | L1 | modules/{slug}/outline.md | Symbols in large files | | L1 | modules/{slug}/memory.md | TODOs, warnings, business rules | | L1 | modules/{slug}/imports.md | File dependencies | | L2 | files/{slug}.md | Deep docs for complex files |

Navigation Flow

INDEX.md → Find module → MODULE.md → outline.md/memory.md → Source file

When To Read What

| You Need | Read This | |----------|-----------| | Project overview | .agentlens/INDEX.md | | Find a module | INDEX.md, search module name | | Understand a module | modules/{slug}/MODULE.md | | Find function/class in large file | modules/{slug}/outline.md | | Find TODOs, warnings, rules | modules/{slug}/memory.md | | Understand file dependencies | modules/{slug}/imports.md |

Best Practices

1. Don't read source files directly for large codebases - use outline.md first
2. Check memory.md before modifying code to see warnings and TODOs
3. Use outline.md to locate symbols, then read only the needed source sections
4. Regenerate docs with agentlens command if they seem stale
