ccc

A tool for searching a codebase by describing what you are looking for in ordinary language. It also creates and updates a searchable index of the project’s code.

In plain words
What is it for?
Use it to locate relevant functions, files, and code patterns, initialise a project for searching, and refresh the index after refactors or new files.
Why use it?
File-name or exact-text searches can miss code that solves the right problem under different names. An indexed search makes it easier to find related code and keeps results current after major changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ccc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
  • 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

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ccc is a skill published in the GitHub repository cocoindex-io/cocoindex-code (2,682 stars, last pushed 2d ago), licensed Apache-2.0. It adds 80 tokens to every session and 720 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
