rag-rat AGENTS.md

Repository instructions for coding agents working on rag-rat, a tool that indexes code and stores useful project memories. They explain how to browse the repository, understand dependencies, and keep durable notes.

In plain words
What is it for?
Use them to search code semantically, look up symbols, assess the impact of edits, consult repository memories, and follow the project’s worktree rules.
Why use it?
They help an assistant find relevant code and past decisions before making changes, reducing the risk of overlooking project-specific constraints.

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

rag-rat AGENTS.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 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.

Prefer the rag-rat MCP for code browsing

This repo ships rag-rat — a local repo-intelligence index and MCP server — and it is indexed by its own server (dogfooded). Heavily prefer the rag-rat MCP tools over raw grep/cat/file reads when browsing or understanding code. One MCP call returns more context, faster, than a shell sweep, and it surfaces drive-by repo memories (source-anchored invariants, decisions, risks) attached to the code you're touching — context you would otherwise never see.

Reach for these first:

  • semantic_search — "where is this concept implemented?" Returns current source chunks with inline graph (callers/callees), git, and GitHub papertrail, all validated against current source.
  • symbol_lookup — exact/fuzzy symbol resolution (Rust/TS/Kotlin/C/C++/Python/Swift/Go), with any bound memories attached.
  • impact_surface — the coding preflight before editing a symbol: graph callers/callees, tests, git history, papertrail, and repo memories crossing the call path. Run it before changing anything non-trivial.
  • find_callers / trace_callees — reverse/forward graph traversal instead of grepping for call sites.
  • read_chunk — current text for a chunk with anchor validation + graph + memories.
  • repo_brief / repo_clusters — orientation (spine, churn, god-modules, ownership clusters).
  • important_symbols — load-bearing symbols by (SCIP-aware) PageRank; pass personalize to bias toward what you're editing. Compiler-grade once rag-rat oracle run has run.

Symbol handle: symbol-returning tools emit id, an opaque sym_<hex> token — the stable handle to cache and pass back into graph/impact/memory tools as the id param (copy verbatim; never parse it as a number). There is no numeric symbol_id on the wire (it's an internal rowid reassigned on every reindex). Use ref (the path::name qualified name) for the human-readable identity. The symbol-tool params are ref / id / lang (formerly symbol_path / logical_symbol_id / language).

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.

rag-rat AGENTS.md is an instructions file published in the GitHub repository cq27-dev/rag-rat (17 stars, last pushed 4d ago), licensed MIT. It adds 2,971 tokens to every session, about $0.0149 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.
