Glean Code

Cross-repository code exploration — search code across your org, find examples, and discover similar implementations.

Leverage Glean's code search to explore beyond your local repository.

Prerequisites

Requires glean-core to be installed first.

Installation

claude plugin install glean-core  # if not already installed
claude plugin install glean-code

What's included

Skill

• using-glean-code — Auto-triggers on cross-repo code questions ("how is X implemented", "where is the code for", "find similar code", "how do other teams handle Y"). The skill teaches the workflow; the canonical code_search tool reference lives in glean-core (see using-glean/reference/code-search.md).

  File	Covers
  exploration.md	Workflow for exploring an unfamiliar system across repos
  plan-prep.md	Gathering enterprise context before entering plan mode

Agents

• codebase-navigator — Navigates internal repositories to find implementations and patterns
• plan-prep-researcher — Gathers design docs, implementations, stakeholders, and related systems for planning

Commands

• /glean-code:codebase-context <system> — Get architectural context from internal repos
• /glean-code:find-examples <API/pattern> — Find usage examples across the org
• /glean-code:code-owners <component> — Identify who owns/maintains code areas
• /glean-code:similar-code <pattern> — Find similar implementations across repos
• /glean-code:plan-prep <task> — Research enterprise context before entering plan mode

Example usage

# Get context before working on a system
/glean-code:codebase-context payments service
/glean-code:codebase-context auth middleware

# Find examples of how others use an API
/glean-code:find-examples AuthClient
/glean-code:find-examples retry logic

# Find who to talk to
/glean-code:code-owners billing module
/glean-code:code-owners src/auth

# Find prior art before building something
/glean-code:similar-code rate limiting
/glean-code:similar-code caching layer

# Research enterprise context before planning
/glean-code:plan-prep Add authentication to API
/glean-code:plan-prep Refactor payment service
/glean-code:plan-prep Implement webhooks

Key differentiator

Local search tools only see your current repo. Glean Code searches across ALL repositories in your organization. This enables:

• Finding examples: "How do other teams handle authentication?"
• Understanding systems: "What repos touch the billing service?"
• Finding owners: "Who's actively working on payments?"
• Avoiding duplication: "Has someone already built a rate limiter?"

Works for monorepos and multi-repo

Whether your company uses a monorepo or multiple repositories, Glean Code searches across everything that's indexed.
