codeindex-guide

A reference guide for CodeIndex, a tool that builds a searchable map of a codebase. It explains the available searches, stored code information, and recommended workflows.

In plain words
What is it for?
Use it to learn how to inspect the code map, check whether its data is current, trace changes that may be affected, investigate failures, and plan refactors.
Why use it?
It helps developers choose the right CodeIndex operation instead of guessing how to search or inspect a project.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

codeindex-guide 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CodeIndex Guide

Quick reference for all CodeIndex MCP tools, resources, and the knowledge graph schema.

Always Start Here

For any task involving code understanding, debugging, impact analysis, or refactoring:

  1. Read codeindex://repo/{name}/context — codebase overview + check index freshness
  2. Match your task to a skill below and read that skill file
  3. Follow the skill's workflow and checklist

In Conductor worktrees, a stale warning can be an overlay/canonical-checkout mismatch rather than a broken shared index. Do not run codeindex analyze or codeindex update from a feature worktree. Run scripts/codeindex-health.sh; only if it reports the shared base index is stale, run scripts/codeindex-health.sh --repair.

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.

codeindex-guide is a skill published in the GitHub repository GetKlai/klai (11 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 781 once invoked, about $0.0003 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.
