create-rule SKILL.md skillA

create-rule from mgiovani/cc-arsenal is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add mgiovani/cc-arsenal/create-rule@v2.0.0

Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Create a new memory/instruction rule for whatever AI coding tool a project.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Create Rule

Generate a new memory rule (a project instruction, coding standard, or workflow
guideline) in whatever format the project's AI tooling actually reads.

This creates **memory rules**, not skills or commands (use `create-skill`) and not a
search for existing skills to install (use `find-skills`).

- Tool conventions, OS-specific paths, and frontmatter formats: [references/memory-hierarchy.md](references/memory-hierarchy.md)
- Worked templates per tool and scope: [references/rule-examples.md](references/rule-examples.md)
- Claude Code memory docs: https://code.claude.com/docs/en/memory

## Anti-hallucination guidelines

- Verify existing patterns first: check the actual codebase, don't assume conventions.
- Base rules on real code found in the project, not invented standards.
- If no convention exists, ask the user rather than making one up.
- Check existing CLAUDE.md / AGENTS.md / `.claude/rules/*.md` / `.cursor/rules/*.mdc` for conflicts before adding a new rule.
- Only use `paths` frontmatter on `.claude/rules/*.md` (Claude Code) or `globs` on `.cursor/rules/*.mdc` (Cursor), never on CLAUDE.md or AGENTS.md, which have no frontmatter.

## Steps

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add mgiovani/cc-arsenal/create-rule@sha256:b0cf974f248f3dfa

The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
