Lore: Instructions file for Claude Code

CLAUDE.md

Lore CLAUDE.md is an instructions file for Claude Code from jafreck/Lore. It costs 611 tokens per session, scanned A, original, MIT.

Developer instructions for Lore, a code-intelligence tool that indexes source code, documentation, relationships, and Git history so agents can query a large codebase.

In plain words
What is it for?
Use them when working on repository indexing, code relationships, documentation or Git-history analysis, and the database exposed through MCP, a standard way for AI tools to access services.
Why use it?
They explain how the project builds structured knowledge about code, helping contributors understand its purpose and follow its development conventions.

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 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 1mo 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.

Project

Lore is a pre-release code-intelligence service. It stores recognized source snapshots and SCIP/LSP-derived facts in SQLite, can add Git history and vector embeddings, and serves the effective index through 11 MCP tools. It has no tree-sitter extraction path, documentation corpus, dependency crawler, or active complexity-metrics producer.

Architecture invariants

  • The active stage order is ScipIndexerStage → FileDiscoveryStage → LspExtractionStage → ImportResolutionStage → [LspEnrichmentStage + git-history] → symbol-resolution → ReverseDepsStage → EmbeddingStage → FtsRefreshStage.
  • Baseline validation and generation promotion occur after the stage pipeline. Promotion is not an active pipeline stage.
  • SCIP is the primary baseline structural source and does not run for overlay updates. LSP extracts changed-file overlays.
  • Baseline LSP supplementation selects every non-SCIP-sourced file and SCIP-sourced C/C++ files with no symbols or repairable spans. It is bounded by supplementation.maxFiles and fileConcurrency; strict mode fails rather than truncating the plan.
  • Schema v3 uses branch-scoped promoted generations, dirty-file selectors, persistent effective_* views, and connection-local staging views. Keep candidate generations hidden until validation succeeds.
  • Public query paths use effective state. When overlays replace targets, reconcile stored file IDs and requeue symbol targets before resolution.
  • Repository .lore.config values are requests, never execution authority. Host grants must remain separate and explicit.

Change policy

Lore may make clean breaking changes before 1.0. Remove dead implementations instead of maintaining parallel APIs, and prefer the smallest complete design.

The current schema contract is different from a compatibility shim: writable opens must apply the declared ordered migrations [1, 2, 3], both schema markers must be present and agree, and read-only consumers must reject incompatible databases. Any schema change must deliberately update the version, migration sequence, capability inspection, and tests. Do not remove required migration behavior merely because the product is pre-release.

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.
