SH AI custom instructions from approved entries: a profile and rules for Claude Code, Codex, Cursor, Gemini CLI, Hermes Agent and ChatGPT, kept in sync from one source.
https://agent-personalizer.aunysillyme.dev ↗// readme
Every AI you use gets the same profile and the rules it can carry: Claude Code, Codex, Cursor, Gemini CLI, Hermes Agent and ChatGPT, rendered from one source and kept in sync.
The problem: Custom instructions live in each app separately, drift apart and fade over a long chat.
What you get: One profile and one rule source, rendered into the exact file each AI reads, with a check that fails when a generated copy drifts.
