cocoindex: Hook for Claude Code

.claude/settings.json

PostToolUse is a hook for Claude Code from cocoindex-io/cocoindex. Its token cost is not measured, scanned A, a copy of SessionStart, Apache-2.0.

A post-tool hook configuration for the CocoIndex project. A hook is an automatic command that runs after a coding action; these hooks check documentation builds and mark or run Python type checks.

In plain words
What is it for?
Use it to run documentation build checks and Python type-checking steps after edits and when the agent stops.
Why use it?
It catches documentation and Python typing issues during the agent's work, reducing the chance that edits leave these checks unresolved.

Hook for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable.

This is cocoindex-io/cocoindex's own configuration. It tells Claude Code how to work on cocoindex itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cocoindex configures →

One of 3 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 2 are separate, each on its own page.

About the project

CocoIndex is an incremental data-processing engine that keeps code, documents, messages, PDFs, and videos continuously updated as context for AI agents and language-model applications. Engineers use it to build declarative Python pipelines that process only changed data, and its catalogue skills help coding agents work with CocoIndex correctly.

Security

Grade A, and why

PostToolUse 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 2mo ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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.

Origin

This is a copy

42% identical to SessionStart — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
