ccc

ccc is a skill for Claude Code from cocoindex-io/cocoindex-code. It costs 80 tokens per session (827 once invoked), scanned A, original, Apache-2.0.

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.

About the project

CocoIndex Code is a command-line code-search engine that analyzes a codebase's syntax trees to find relevant code and provide it to language models. It is for developers and coding agents that need fast, context-aware codebase search, with integrations for tools such as Claude, Codex, and Cursor. The catalogue add-ons are its plugin, skill, hook, and MCP integrations for coding agents.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 9d ago.

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.
    • 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.

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.

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.
