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

Skills

  • code-exploration - Guidance for cross-repo code search, triggers on implementation questions
  • plan-prep - Research enterprise context before entering plan mode, triggers on planning-related phrases

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.

Planning with Enterprise Context

The plan-prep command brings enterprise knowledge into your planning process:

  • Research Before Planning: Use /glean-code:plan-prep to gather design docs, similar implementations, and stakeholder info
  • Better Decisions: See what's been tried, what patterns are proven, and who needs to be involved
  • Informed Architecture: Make decisions informed by organizational knowledge and prior art

Example workflow:

  1. Run /glean-code:plan-prep "Add webhook support to payments service"
  2. Review the enterprise context: design decisions, similar implementations, stakeholders
  3. Enter plan mode with this fresh knowledge
  4. Design your approach informed by organizational patterns and constraints
