In plain words

Why use it?
They keep repository changes consistent and prevent edits to generated files or related configuration from being missed.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is patrickclery/ruly's own configuration. It tells Claude Code how to work on ruly itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ruly configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/patrick/.local/share/mise/installs/ruby/3.3.3/bin/ruly.

Reuse

Borrowing it

Nothing to install: this file belongs to patrickclery/ruly. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

ruly 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.

How it starts

The opening of the file, as written. The whole thing — 353 lines — stays where its author put it; the contents beside it link to each section on GitHub.

  • Shared recipe definitions live in recipes.yml at the root of the rules repo (https://github.com/patrickclery/rules), using repo-relative paths. ~/.config/ruly/recipes.yml holds only remotes: and overrides: (per-machine additions). ~/.config/ruly/remotes/ is generated by ruly squash --sync — never edit it.
  • Every time the slash commands are updated, make sure to update the slash command section of README.md
  • When changing ruly CLI commands (squash, clean, analyze, mcp, etc.), always update README.md to reflect the changes
  • NEVER edit CLAUDE.local.md — it is generated output from ruly squash and will be overwritten. Fix the source rules in ./rules/ instead.
  • When I ask to change rules, don't change the rules in .claude/ always look in ./rules/
  • When I ask to create a skill, add it to rules/{tag}/skills/{skill-name}.md (Ruly searches for skills in that structure)
  • Skills in rules/ are regular .md files, NOT SKILL.md - Ruly converts them to SKILL.md format on squash
  • Always use git mv to move/rename files instead of deleting and re-creating them (preserves git history)
  • When deleting/moving/renaming files in rules/, always search for references to update:
    • requires: frontmatter in other rule files
    • Recipe files (recipes.yml in the rules repo, ~/.config/ruly/recipes.yml, .recipes.yml)
    • Section anchor links that may have changed
  • When I say "commit" or "commit all", commit and push ALL modified files in BOTH repos (don't assume any changes are unrelated):
    1. The rules submodule (./rules) → https://github.com/patrickclery/rules
    2. The parent ruly repo → https://github.com/patrickclery/ruly (update submodule reference)
  • Always use Mermaid for diagrams/flowcharts in rules (never graphviz/dot). Exception: Jira/Confluence don't support Mermaid, so use ASCII diagrams there instead.

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.
