name: gsd-map-codebase description: "Analyze codebase with parallel mapper agents to produce .planning/codebase/ documents" argument-hint: "[--fast [--focus tech|arch|quality|concerns]] [--query <term>|status|diff|refresh] [area]" allowed-tools: Read, Bash, Glob, Grep, Write, Agent

<objective> Analyze existing codebase using parallel gsd-codebase-mapper agents to produce structured codebase documents.

Each mapper agent explores a focus area and writes documents directly to .planning/codebase/. The orchestrator only receives confirmations, keeping context usage minimal.

Output: .planning/codebase/ folder with 7 structured documents about the codebase state. </objective>

<execution_context> @.github/get-shit-done/workflows/map-codebase.md </execution_context>

<flags> - **--fast**: Lightweight scan mode — spawns one mapper agent instead of four. Accepts an optional `--focus` value: `tech`, `arch`, `quality`, `concerns`, or `tech+arch` (default). Faster and lower-context than the full map. - **--query**: Codebase intelligence query mode. Sub-commands: `query <term>`, `status`, `diff`, `refresh`. Requires intel to be enabled in config (`intel.enabled: true`). Runs inline for query/status/diff; spawns an agent for refresh. - **(no flag)**: Full parallel map — spawns 4 mapper agents to produce all 7 codebase documents. </flags> <context> Arguments: $ARGUMENTS

Parse the first token of $ARGUMENTS:

• If it is --fast: strip the flag, run the scan workflow (passing remaining args including optional --focus).
• If it is --query: strip the flag, run the intel workflow (passing remaining args as the subcommand).
• Otherwise: pass all of $ARGUMENTS as focus area to the map-codebase workflow.

Load project state if exists: Check for .planning/STATE.md - loads context if project already initialized

This command can run:

• Before /gsd-new-project (brownfield codebases) - creates codebase map first
• After /gsd-new-project (greenfield codebases) - updates codebase map as code evolves
• Anytime to refresh codebase understanding </context>

<when_to_use> Use map-codebase for:

• Brownfield projects before initialization (understand existing code first)
• Refreshing codebase map after significant changes
• Onboarding to an unfamiliar codebase
• Before major refactoring (understand current state)
• When STATE.md references outdated codebase info

Skip map-codebase for:

• Greenfield projects with no code yet (nothing to map)
• Trivial codebases (<5 files) </when_to_use>

<process> 1. Check if .planning/codebase/ already exists (offer to refresh or skip) 2. Create .planning/codebase/ directory structure 3. Spawn 4 parallel gsd-codebase-mapper agents: - Agent 1: tech focus → writes STACK.md, INTEGRATIONS.md - Agent 2: arch focus → writes ARCHITECTURE.md, STRUCTURE.md - Agent 3: quality focus → writes CONVENTIONS.md, TESTING.md - Agent 4: concerns focus → writes CONCERNS.md 4. Wait for agents to complete, collect confirmations (NOT document contents) 5. Verify all 7 documents exist with line counts 6. Commit codebase map 7. Offer next steps (typically: /gsd-new-project or /gsd-plan-phase) </process>
