Always on: put it where your tool reads instructions every session:
Any AI
Coding agent: save as AGENTS.md in the project root (read natively by Codex, Cursor, Copilot, Gemini CLI, Kiro, Devin, Cline, Roo, OpenHands, OpenCode, Goose, Amp, Zed, Warp, Junie, Factory and Jules; Claude Code when no CLAUDE.md exists; Aider with --read). Chat: paste it first.
Reload: new session
Check it loaded: ask it to repeat one rule from the file
Checked against the official page on 2026-10-12.
Claude Code
Save as CLAUDE.md in the project root, or .claude/CLAUDE.md. Other agents share the repo: put the shared rules in AGENTS.md and make CLAUDE.md one line, @AGENTS.md. Commit it. Start a new session: the file is read at launch.
Reload: new session (or /memory to open the files)
Check it loaded: /context lists the Memory files it read; /skills, /agents, /hooks list the rest; the InstructionsLoaded hook event fires once per loaded instruction file
Checked against the official page on 2026-10-12.
Codex
Save as AGENTS.md in the repo root. Codex concatenates AGENTS.md from the git root down to the working directory, closer wins. Commit it. Start a new session.
Reload: new session
Check it loaded: ask: Summarize the current instructions; codex status
Checked against the official page on 2026-10-12.
Cursor
Save as AGENTS.md in the repo root, or as .cursor/rules/<name>.mdc with alwaysApply: true in its frontmatter. Commit it. Reopen the project so it reindexes.
Reload: reopen the project
Check it loaded: Cursor Settings → Rules shows each rule and its status; no per-reply indicator
Checked against the official page on 2026-10-12.
Cline
Save as .clinerules/<name>.md in the repo root (a folder, not the old single file), or as AGENTS.md. Commit it. Start a new task.
Reload: new task
Check it loaded: the Rules panel; the reply shows 'Conditional rules applied: …' for path rules
Checked against the official page on 2026-10-12.
OpenHands
Save as AGENTS.md in the repo root. Keyword snippets go in .agents/skills/<name>/SKILL.md with a triggers: list. Commit. Start a new conversation after edits.
Reload: new conversation
Check it loaded: Agent Canvas → Customize → Skills
Checked against the official page on 2026-10-12.
Open WebUI
Workspace → Models → your model → System Prompt: paste the text and save. Long reference goes in Knowledge and is retrieved, not always loaded.
Reload: start a new chat
Check it loaded: the model's System Prompt field; ask the model to repeat one rule
