lore-index

lore-index is a skill for Claude Code, Codex from hyunjae-labs/lore. It costs 143 tokens per session (970 once invoked), scanned A, original, MIT.

A skill for managing Lore, a search index of past Claude Code and OpenAI Codex CLI conversations. It explains how projects are included or excluded and how to check indexing status before changing it.

In plain words
What is it for?
Use it to check indexing status, list projects, exclude or include projects, and guide an indexing or project-management operation before using Lore’s management tools.
Why use it?
It helps prevent accidental indexing decisions by showing what is already indexed and clarifying that projects are included by default unless explicitly excluded.

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

lore-index 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 10d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Lore Indexing & Project Management

Lore uses an opt-out (blacklist) model: ALL projects are indexed by default. Users can exclude specific projects they don't want indexed.

Two source agents are indexed in the same DB:

  • Claude Code sessions from ~/.claude/projects/ (override with CLAUDE_PROJECTS_DIR)
  • OpenAI Codex CLI sessions from ~/.codex/sessions/ (override with CODEX_SESSIONS_DIR)

Codex sessions are grouped by cwd (read from each file's session_meta line) and surfaced as virtual projects with a codex- dirName prefix. The same project working directory may appear twice in the list — once as a Claude Code project (no prefix) and once as a Codex project (codex- prefix). They are independent rows; excluding one does not affect the other.

First-Time Setup

If the user has never used lore indexing before, or asks to index without context, walk them through:

  1. Check current state first -- call status to see if anything is indexed, then manage_projects(action: "list") to see available projects.
  2. Explain what they're looking at:
    • How many projects exist, how many are excluded. By default, all are indexed.
  3. Ask what they want:
    • Index everything (just run index())? Exclude certain projects first?
  4. Execute based on their answer.

Do not skip the explanation step. The user needs to understand what's happening.

Index Options

User intent Tool call Existing data
Index everything (default) index() -- incremental index for all non-excluded projects Preserved
Index a specific project index(project: "/full/path/to/project") -- indexes that project (even if excluded) Preserved
Start fresh index(mode: "rebuild") -- deletes ALL indexed data and re-indexes from scratch Deleted
Stop running index index(mode: "cancel") --

Important: Always use full project paths, not fuzzy names. Never summarize or drop rows from tool results when presenting to the user.

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.
