map

An on-demand codebase analysis command that examines a project's technology, architecture, quality, or technical concerns. A codebase is the collection of source files that make up a software project.

In plain words
What is it for?
Use it to map languages and dependencies, document system structure, review coding and testing practices, or identify technical debt and risks.
Why use it?
It gives you a structured view of an unfamiliar project instead of requiring you to inspect every file manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

map scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/shipyard:map - On-Demand Codebase Analysis

You are executing on-demand codebase analysis. Follow these steps precisely.

Step 1: Parse Arguments

Extract from the command:

  • focus (optional): Analysis focus area. Accepts:
    • No argument / "all": Run all 4 focus areas in parallel (dispatches 4 mapper agents)
    • "technology": Map technology stack — languages, frameworks, dependencies, build tools (produces STACK.md + INTEGRATIONS.md)
    • "architecture": Map system architecture — patterns, layers, boundaries, data flow (produces ARCHITECTURE.md + STRUCTURE.md)
    • "quality": Map code quality — conventions, testing, patterns (produces CONVENTIONS.md + TESTING.md)
    • "concerns": Map technical debt — outdated deps, security risks, performance issues (produces CONCERNS.md)

Step 2: Detect Context

  1. Check if .shipyard/ exists (optional — this command works anywhere).
  2. If .shipyard/config.json exists, read model_routing.mapping for model selection and codebase_docs_path for the output directory.
  3. Otherwise, use default model: sonnet and default codebase_docs_path: .shipyard/codebase.
  4. Follow Worktree Protocol (see docs/PROTOCOLS.md) — detect worktree context.
  5. Store the resolved codebase_docs_path for use in Steps 3 and 5.

Step 2a: Team or Agent Dispatch

Detection: Check the SHIPYARD_TEAMS_ENABLED environment variable (exported by scripts/team-detect.sh). This variable is set to true when CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

Prompt (conditional): If SHIPYARD_TEAMS_ENABLED=true, use AskUserQuestion with exactly two options:

  • "Team mode (parallel teammates)" — uses TeamCreate/TaskCreate/SendMessage/TeamDelete lifecycle
  • "Agent mode (subagents)" — uses standard Task dispatch (current behavior)

Question text: "Teams available. Use team mode (parallel teammates) or agent mode (subagents)?"

Silent fallback: If SHIPYARD_TEAMS_ENABLED is false or unset, silently set dispatch_mode to agent with no prompt (zero overhead).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

map is a command published in the GitHub repository lgbarn/shipyard (65 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 1,674 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
