Need help deploying codebase-understanding?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/cellrishi-code-codebase-understanding
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# Codebase Understanding Build understanding before proposing edits. Prefer evidence from the repository over assumptions. ## Process 1. Identify entry points, package/build files, configuration, tests, and documentation. 2. Map the relevant directory structure. 3. Trace the execution path for the requested feature or bug. 4. Identify important data models, interfaces, dependencies, and integration boundaries. 5. Search for existing implementations before proposing new ones. 6. Record constraints, conventions, and likely regression points. 7. Summarize the model in a compact form before changing code. ## Rules - Read targeted files before broad exploration. - Do not invent architecture that is not supported by repository evidence. - Prefer existing abstractions over introducing parallel ones. - Distinguish observed facts from hypotheses. - If the change crosses multiple layers, state the dependency order. ## Output Return: - Repository map - Relevant execution/data flow - Existing patterns to reuse - Constraints and risks - Proposed change locations - Verification plan
