# zoom-out > A small Matt Pocock Claude Code skill that tells the agent to step up one layer of abstraction and give a map of the relevant modules and callers — using the project's domain glossary vocabulary — when you're navigating an unfamiliar section of code. **Use case**: Ask the agent for a higher-level map of unfamiliar code **Canonical URL**: https://agentcookbooks.com/skills/zoom-out/ **Topics**: claude-code, skills, context-engineering **Trigger phrases**: "zoom out", "give me the bigger picture", "map the modules in this area" **Source**: [Matt Pocock](https://github.com/mattpocock/skills/tree/main/skills/engineering/zoom-out) **License**: MIT --- ## What it does `zoom-out` is one of the smallest skills in the Pocock collection — a single instruction, no sub-docs, no procedures. When triggered, the agent stops what it was doing line-by-line and emits a map of the relevant modules and their callers for the area you're navigating, using the project's *own* domain glossary vocabulary rather than generic English. The skill is marked `disable-model-invocation: true` in its frontmatter, which means it's intended to be invoked explicitly rather than auto-fired by the model on a keyword guess. You ask for it; the agent doesn't decide for you. ## When to use it Reach for it when: - You've been dropped into an unfamiliar section of a large codebase and the line-level view isn't telling you *why* anything is shaped the way it is - You're about to plan a refactor or feature in territory you haven't navigated before, and you want a structural read before committing to an approach - The previous few messages are deep in a single function and you've lost the surrounding context - You're onboarding to a project and want a forced re-orientation at a domain-vocabulary level rather than a file-tree level When *not* to reach for it: - You already have the structural picture — the output would duplicate what you already hold - The codebase has no `CONTEXT.md` or shared glossary; the instruction "use the project's domain vocabulary" can degrade into generic English without it ## Install The skill is distributed via Pocock's [skills repo](https://github.com/mattpocock/skills). Install via his recommended path (`npx skills add` or manual copy of the `SKILL.md` into `.claude/skills/zoom-out/`) — see the repo README for canonical install instructions. Once installed, invoke explicitly with one of the trigger phrases above. ## What a session looks like A typical use is a single round-trip: you trigger the skill, the agent produces the map (modules, primary callers, the seams between them), and you read it before deciding the next step. The agent doesn't continue with the original task automatically — the skill is structural reflection, not a workflow. The map quality tracks the quality of the project's shared vocabulary. On a codebase with a maintained `CONTEXT.md` or glossary, the output reads like a domain map. On a codebase without one, the output drops to a generic-English module list — useful but lower-leverage. ## Receipts TODO — to be filled in from a real session. When the skill is triggered in production use, capture: which area of the codebase you were in, what the map surfaced that the line-level view hadn't, and whether the project's domain glossary made the output domain-specific or generic. ## Source and attribution Originally written by [Matt Pocock](https://github.com/mattpocock).
