# Plan-first protocol > Make the AI write PLAN.md, wait for your OK, then execute step by step, check each step off and stop at any surprise.

Chat: paste it first. Reload: new session. Check it loaded: ask it to repeat one rule from the file. Source: https://agents.md/ (checked 2026-10-12). - Any text chat: Paste the whole file as your first message, then your task. A chat cannot read files or run commands: it must hand you the command and wait for the output. Reload: paste it again in a new chat. Check it loaded: ask it to repeat one rule from the file; a general answer means it is not in context. Source: https://videotomd.com/use-with-your-ai/ (checked 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. Source: https://code.claude.com/docs/en/memory (checked 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`. Source: https://learn.chatgpt.com/docs/agent-configuration/agents-md (checked 2026-10-12). - Cursor: Save as AGENTS.md in the repo root, or as .cursor/rules/.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. Source: https://cursor.com/docs/context/rules (checked 2026-10-12). - Cline: Save as .clinerules/.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. Source: https://docs.cline.bot/customization/cline-rules (checked 2026-10-12). - Roo Code: Save as .roo/rules/.md in the repo root, or as AGENTS.md. Commit it. Start a new task. Reload: new task. Check it loaded: the system prompt block USER'S CUSTOM INSTRUCTIONS shows '# Rules from {path}:'. Source: https://roocodeinc.github.io/Roo-Code/features/custom-instructions (checked 2026-10-12). - OpenCode: Save as AGENTS.md in the project root. Commit it. Start a new session. Reload: new session. Check it loaded: none documented: ask it to repeat one rule from the file. Source: https://opencode.ai/docs/rules (checked 2026-10-12). - Aider: Save as CONVENTIONS.md and add `read: [CONVENTIONS.md]` to .aider.conf.yml, or start with `aider --read CONVENTIONS.md`. Aider does not read AGENTS.md on its own: pass it with --read too. Reload: restart aider. Check it loaded: none documented: ask it to repeat one rule from the file. Source: https://aider.chat/docs/usage/conventions.html (checked 2026-10-12). - Ollama: Put the text in a Modelfile as SYSTEM """...""" with FROM and PARAMETER num_ctx , then `ollama create -f Modelfile` and run . Chat-only: paste it as the first message instead. Reload: ollama create again. Check it loaded: `ollama show --modelfile ` prints the SYSTEM; `ollama ps` shows the loaded context size.

A member's browser downloads the file there; an AI without that session needs the member to attach it.
