rules

An instruction set for using greplm, a code-search and navigation tool, instead of grep, ripgrep, or find. It also covers symbol navigation, structural searches, call relationships, and code history.

In plain words
What is it for?
Use it to search a codebase, load task-specific context, find definitions and callers, trace impact, inspect structure, or review when code changed.
Why use it?
It helps an agent locate relevant code and understand relationships without opening many unrelated files.

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

rules 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.

What it actually says

Code search & navigation: prefer greplm

Use greplm instead of grep/ripgrep/find for searching and navigating this codebase. It returns ranked, jump-ready locations with real code intelligence (call graph, typed go-to-definition, structural/AST search, git history) and is far cheaper on context than reading whole files.

  • Search: greplm search "<query>" — add --word (whole identifier), -e '<regex>', --lang <lang>, or --exhaustive for grep-parity full matches.
  • Task context: greplm pack "<task>" --budget 8000 — load exactly the relevant code instead of opening files blindly.
  • Navigate: greplm def <file> <line> <col>, greplm callers <sym>, greplm callees <sym>, greplm impact <sym>, greplm xref <sym>.
  • Structural: greplm ast '<pattern>' --lang <lang> for matches regex can't express.
  • History: greplm blame <file> <line>, greplm history <sym>, greplm changed <rev>.

Run greplm index once to build/refresh the index (incremental; indexed 0 files means nothing changed, not an empty index). greplm serve keeps it hot for an agent loop. Add --json for machine-readable output.

Drop to raw grep only for a quick one-off confirmation of an exact string.

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.

rules is an agent published in the GitHub repository KhaledSMQ/greplm (14 stars, last pushed 21d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 335 tokens. 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.
