One search for your own team's files and the public ecosystem. See how real projects write their agent instructions, and bring the good ideas home.
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.

Audit a draft X (Twitter) post or thread against the open-source X algorithm BEFORE publishing. Use when the user shares a tweet draft and wants feedback, asks "will this do well on X / Twitter", "review my post", "is this good to post", or wants to improve reach before posting. Returns a PASS / FLAG / BLOCK verdict per dimension plus a concrete rewrite.

Write or rewrite the first line (hook) of an X (Twitter) post. Use when the user has content, an idea, or a finished post and wants a stronger opening, asks "make this hook better", "how should I start this tweet", "my posts get no engagement", or wants scroll-stopping first lines. Returns ranked hook variants with reasoning.

Audit an X (Twitter) profile — handle, display name, bio, header, pinned post — for follow conversion. Use when the user asks "review my X profile", "improve my bio", "why don't visitors follow me", "audit my Twitter profile", or shares their profile details.

Reverse-engineer why an X (Twitter) post went viral or flopped, mechanism by mechanism. Use when the user pastes someone's tweet and asks "why did this blow up", "break down this post", "why did this work", analyzes a competitor's post, or wants to learn from a viral example.

Returns a numbered thread with a standalone first post.
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
