elroy CLAUDE.md

elroy CLAUDE.md is an instructions file for coding agents from elroy-bot/elroy. It costs 259 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Elroy that define how to build, test, format, lint, and review its code. They also explain how to find available commands and where the project roadmap is kept.

In plain words
What is it for?
Use them when running checks, building the project, preparing code for review, finding available commands, or updating roadmap items.
Why use it?
They prevent developers and coding agents from using the wrong commands or inventing review rules. They provide one shared reference for validation and project priorities.

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

elroy 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 4d 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

Claude Code Configuration for Elroy

Build and Test Commands

IMPORTANT: This project uses just as a command runner. Always use just commands instead of running build/test tools directly.

Common Commands

  • Run tests: just test (NOT pytest or python -m pytest)
  • Run specific test: just test <test_path>
  • Build: just build (NOT python -m build or similar)
  • Lint: just lint
  • Format: just format

Finding Available Commands

Run just --list to see all available commands for this project.

Code Review Standard

Use CODE_REVIEW.md as the source of truth for code review expectations in this repository.

During review:

  • Apply the role, dependency, and validation rules defined in CODE_REVIEW.md
  • Do not duplicate or invent competing review standards in review comments
  • Treat just lint and just typecheck as required validation before code is ready for review

Project Roadmap

Reference ROADMAP.md for current priorities, and update it when completing roadmap items or adding new ones.

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.
