ccc

This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the index', 'ccc', 'cocoindex-code'.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/cocoindex-io/cocoindex-code --skill ccc
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads ccc automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

It facilitates the installation of the tool, management of its local daemon, and execution of search queries against a project's codebase. While the skill processes project files which could theoretically contain instructions designed to influence the agent (indirect prompt injection), it follows industry standard practices for developer tooling and utilizes legitimate vendor-owned packages.

ccc - Semantic Code Search & Indexing

ccc is the CLI for CocoIndex Code, providing semantic search over the current codebase and index management.

Ownership

The agent owns the ccc lifecycle for the current project — initialization, indexing, and searching. Do not ask the user to perform these steps; handle them automatically.

  • Initialization: If ccc search or ccc index fails with an initialization error (e.g., "Not in an initialized project directory"), run ccc init from the project root directory, then ccc index to build the index, then retry the original command.
    • Exception: if ccc index refuses because the directory holds ccc's user settings directory (usually your home directory), do not run ccc init there. Run ccc from inside the project instead, or ask the user which project to use.
    • Exception: if a ccc note says the project in use is that directory (a repo below it has no project of its own), tell the user. Do not run ccc reset there yourself: whether it should stay a project is the user's call.
  • Index freshness: Keep the index up to date by running ccc index (or ccc search --refresh) when the index may be stale — e.g., at the start of a session, or after making significant code changes (new files, refactors, renamed modules). There is no need to re-index between consecutive searches if no code was changed in between.
  • Installation: If ccc itself is not found (command not found), refer to management.md for installation instructions and inform the user.

Searching the Codebase

To perform a semantic search:

ccc search <query terms>

The query should describe the concept, functionality, or behavior to find, not exact code syntax. For example:

ccc search database connection pooling
ccc search user authentication flow
ccc search error handling retry logic

Filtering Results

  • By language (--lang, repeatable): restrict results to specific languages.

    ccc search --lang python --lang markdown database schema
    
  • By path (--path): restrict results to a glob pattern relative to project root. If omitted, defaults to the current working directory (only results under that subdirectory are returned).

    ccc search --path 'src/api/*' request validation
    

Pagination

Results default to the first page. To retrieve additional results:

ccc search --offset 5 --limit 5 database schema

If all returned results look relevant, use --offset to fetch the next page — there are likely more useful matches beyond the first page.

Working with Search Results

Search results include file paths and line ranges. To explore a result in more detail:

  • Use the editor's built-in file reading capabilities (e.g., the Read tool) to load the matched file and read lines around the returned range for full context.
  • When working in a terminal without a file-reading tool, use sed -n '<start>,<end>p' <file> to extract a specific line range.

FAQ

What does the ccc skill do?

This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the index', 'ccc', 'cocoindex-code'.

How do I install ccc?

Run npx skills add https://github.com/cocoindex-io/cocoindex-code --skill ccc in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/ccc/ (personal) or .claude/skills/ccc/ (project).

Which AI agents can use ccc?

Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.

Is ccc safe to install?

Security partners have reviewed it: Gen Agent Trust Hub passed; Socket passed; Snyk passed; ZeroLeaks passed. As with any skill, read the SKILL.md and bundled scripts before installing.

Who maintains ccc?

It is published by cocoindex-io in cocoindex-io/cocoindex-code. It has 5,964 recorded installs.
