Build Claude Desktop mods, plugins, or .mcpb extensions in this repo. Load the matching project skill first.
We split this claude-desktop-skills.mdc into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

When the task is to create or debug something for Claude Desktop, read the matching skill before writing code:
≈ “Common” is an estimate: at least 1 in 5 of the 6,350 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.

Load the matching project skill first. alwaysApply: false --- # Claude Desktop build skills (repo-local) When the task is to create or debug something for Claude Desktop, read the matching skill before writing code: | Build a... | Skill | | --- | --- | | Mod (JS module in Claude Code: hooks, panes, UI) | `.agents/skills/claude-desktop-mods/SKILL.md` | | Mod recipes (Token Weather, Blast Radius, Replay Theater; mod vs hook/skill/MCP) | `.agents/skills/claude-code-mods-guide/SKILL.md` | | Plugin (skills, commands, agents, hooks, MCP/LSP; requirements, publishing) | `.agents/skills/claude-desktop-plugins/SKILL.md` | | Extension (`.mcpb` local MCP server bundle) | `.agents/skills/claude-desktop-extensions/SKILL.md` | A mod is a plugin plus a module; start with the plugins skill when unsure. ## Maintaining them - `.agents/skills/` is canonical. `.claude/skills/` is a mirror for Claude Code. After editing, run `node scripts/sync-project-skills.mjs`; `npm test` fails on drift. - These skills are repo-only. Never add `.agents` or `.claude` to `package.json` `files`, and never move them into `skills/` (that autoloads with the Mental plugin). - Re-verify against the live docs before changing facts (`https://code.claude.com/docs/llms.txt`); Claude Desktop surfaces change quickly.
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 3,978 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.

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.
