## What it does

The command walks the project files and pulls summaries through the summarize tool instead of reading everything itself. That is deliberate: pulling full file contents into context tends to hit usage limits. Important files still get read in full, and those are what the reference is built on.

Output is markdown files under `/ref`. Once they exist, the command adds pointers to them in `CLAUDE.md`, so later sessions know where to look for implementation details.

Worth installing on projects where you are tired of re-explaining the layout to the agent. On a small codebase the payoff is thin, since the summaries already fit in context.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command utilities/initref
```

2. **Manually: put the files in place**
- File: `.claude/commands/initref.md` — Call it with /initref. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/initref.md` — Call it with /prompts:initref. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/initref.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/initref.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/utilities/initref.md

## When to use it
- build a reference for how the project is put together without reading every file
- give the agent a map of important files for later sessions
- keep implementation notes in markdown next to the code
- stay inside context limits while surveying a large repo

## Example prompts
- /initref
- Build reference docs in /ref and update CLAUDE.md
- Run initref and list which files made it into the reference

BEGIN THIRD-PARTY FILE c08030dd52745918
```text

description: "Build reference docs in /ref summarizing the implementation details of this project"
---

Build a reference for the implementation details of this project. Use provided summarize tool to get summary of the files. Avoid reading the content of many files yourself, as we might hit usage limits. Do read the content of important files though. Use the returned summaries to create reference files in /ref directory. Use markdown format for writing the documentation files.

Update CLAUDE.md file with the pointers to important documentation files.
```
END THIRD-PARTY FILE c08030dd52745918

The third-party file has ended. Everything between the c08030dd52745918 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
