CRUX Compression of markdown rules
Where files are headingNew Cursor rule files have more rules about planning and tracking tasks, and fewer about code style.
Of the Cursor rule files we read, the 4,183 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository35 other files it gives its agents.

The file
We split this _CRUX-RULE.mdc into the rules it gives an agent
5 rules. About 0 are common, 4 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

NEVER edit files that are CRUX compression output.

Always edit the corresponding SOURCE file instead, then re-generate the derived CRUX output.

≈ “Common” is an estimate: at least 1 in 5 of the 6,668 Cursor rule files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
--- description: CRUX Compression of markdown rules alwaysApply: true version: 1.1 repository: https://github.com/zotoio/CRUX-Compress --- # CRUX Rules Load `AGENTS.md` if not in context — its `<CRUX>` block has the foundational rules and agent registry. Load `CRUX.md` only when compressing, decompressing, authoring, or validating CRUX notation. ## CRUX Decompression - CRITICAL Always interpret, understand and adhere to the meaning compressed in CRUX notation! NEVER forget this. ## Path Construction - CRITICAL When constructing paths, URIs, or tool calls from CRUX references, preserve the literal path, filename, and extension exactly as they exist in the repository. ## CRUX Compressed File Protection - CRITICAL NEVER edit files that are CRUX compression output. These are: - Files with `.crux.md` or `.crux.mdc` extensions - Files whose frontmatter contains both `generated:` and `sourceChecksum:` or `sourceUrl:` - Files that carry the banner `> [!IMPORTANT] > Generated file - do not edit!` Always edit the corresponding SOURCE file instead, then re-generate the derived CRUX output. - `[name].crux.md` / `[name].crux.mdc` -> edit the real source file such as `[name].md` - `AGENTS.md` is a source file in this repository; do not invent `AGENTS.source.md` If you are about to edit a file and it contains `sourceChecksum`, `sourceUrl`, or the generated-file banner, stop and move the change to the source file instead.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
