What is cocoindex CLAUDE.md?

Project-specific instructions for working on CocoIndex, an open-source incremental engine for long-running AI agents. An instruction file tells a coding agent how to handle a particular repository.

Use it when making changes in the CocoIndex repository and needing its local agent instructions.

It gives the agent repository context and working rules that may not be obvious from the source code.

How cocoindex-io/cocoindex configures Claude Code

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00011	$0.00011
Opus 5.5	$0.00004	$0.00004

Security

Grade A, and why

cocoindex CLAUDE.md 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 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.

Origin

This is a copy

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.
