Codemap

skill-shalomb-agent-skills-codemap · by shalomb

Analyze codebase structure, dependencies, changes, and multi-agent handoffs using codemap. Use this skill as the primary entry point when a task requires understanding project architecture, mapping dependencies, tracing logic, or generating cross-agent handoff artifacts. Always trigger this first when exploring unfamiliar code or when codemap output indicates noisy configurations.

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Codemap

Gives instant architectural context: project tree, dependency flow, hub detection, diff, intent classification, and multi-agent handoff.

Commands

codemap .                       # Project tree with file counts and top files
codemap --deps .                # Dependency flow + hub files (requires ast-grep)
codemap --diff                  # Changes vs main branch
codemap --diff --ref    # Changes vs specific branch
codemap --importers       # Who imports this file? Is it a hub?
codemap handoff .               # Build + save cross-agent handoff artifact
codemap handoff --latest .      # Read latest saved handoff
codemap skill list              # Show available skills
codemap skill show        # Load full skill instructions
codemap config show             # Show current project config
codemap context --compact       # Minimal JSON context envelope

First-Use Setup

Before deeper analysis in a new repo:

  1. Run codemap . — if output is noisy or config is missing, run codemap skill show config-setup first
  2. Run codemap --deps . — dependency graph and hub files
  3. Config is repo memory: once tuned, all future calls benefit automatically

When to use

| Situation | Command | |---|---| | Starting any task | codemap . | | "Where is X?" / "What uses Y?" | codemap --deps . | | About to edit a file | codemap --importers | | "What changed?" / before committing | codemap --diff | | Switching agents / resuming work | codemap handoff . | | Config missing or output noisy | codemap skill show config-setup | | Risk warning in hook output | codemap skill show |

Hook output

The prompt-submit hook fires on every message and emits:


Skills matched: hub-safety, explore — run `codemap skill show ` for guidance

Skills are pull-based — names are surfaced automatically, full body loaded only when needed.

Builtin skills

| Skill | When to load | |---|---| | config-setup | Config missing, boilerplate, or output noisy | | hub-safety | Editing a file with 3+ importers | | explore | Understanding how code works | | handoff | Switching between agents |
