DevAgentRadar → Repo Harness Rule Patch

Goal: update our repository's permanent harness instructions based on this release.

Update the file that tool actually reads. Do not dump everything into one file.

• Claude Code → CLAUDE.md plus .claude/ (skills, hooks, settings, agents, commands). It does not read AGENTS.md natively; start CLAUDE.md with @AGENTS.md.
• Codex, Copilot, Cursor, Factory Droid, Grok Build, Roo Code, Goose, OpenCode, Amp, Zed, Aider → AGENTS.md.
• Gemini CLI / Antigravity → GEMINI.md. AGENTS.md only if context.fileName is set.
• Cursor glob-scoped rules → .cursor/rules/*.mdc (plain .md is ignored), not a second constitution.
• Codex MCP → .codex/config.toml, not .mcp.json.
• Copilot extra instructions → .github/copilot-instructions.md; custom agents → .github/agents/.
• Windsurf → .windsurf/rules (do not assume AGENTS.md).
• Cline → .clinerules.
• Procedures → a skill (SKILL.md). Enforcement the model must not skip → a hook. Isolated roles → subagents.
• Do not fork the same rule into three tool files.

Context

Assistant: Zed AI Proposal: Upgrade Zed to v1.25.0-pre and rotate leaked remote-agent MCP secrets Summary: Zed v1.25.0-pre adds ACP context compaction and session notices for external agents, Gemini 4 Argon plus new Bedrock models, and stops remote-project agent/MCP secrets from appearing in the local process list. Upgrade, rotate those secrets, and point agents at gemini-4-argon or the new Bedrock models. Primary source: https://github.com/zed-industries/zed/releases/tag/v1.25.0-pre

Why it matters

This prerelease is worth adopting immediately if you run external agents or MCP servers over SSH remotes: environment variables, including secrets, were visible in the local process list (#65174). After you upgrade, rotate every key that was injected that way. The same build enables session notices and context compaction for ACP external agents (#65414), so long threads can stay open instead of being restarted to manage context. It also fixes prompts that were slow or never sent because of unneeded Git checkpoints (#65304) and first updates that were dropped in new threads (#65339). Update model routing now that the Google AI provider includes gemini-4-argon and Amazon Bedrock includes GPT-6 Astra, Claude Fable 5.1, and Claude Opus 5.5. In the editor, apply inlay hint edits with a double-click or editor: accept inlay hint, and rely on automatic unfolding when jumping to a location. Do not infer anything from the unpublished extra change.

Suggested actions

1. Install Zed v1.25.0-pre from https://github.com/zed-industries/zed/releases/tag/v1.25.0-pre and fully restart so ACP session notices, context compaction, the remote MCP/agent env-var process-list fix (#65174), and faster external-agent prompts (#65304) are active.

2. Rotate every API key and secret previously passed as an environment variable to external agents or MCP servers in SSH remote projects; those values were visible in the local process list before this build, then reconnect the remote project on v1.25.0-pre.

3. In Zed Agent / Google AI settings, set the model id to gemini-4-argon. If you use Amazon Bedrock, add GPT-6 Astra, Claude Fable 5.1, and Claude Opus 5.5 to the Bedrock provider.

4. Keep long-running external ACP agent threads open and use the new context compaction and session notices instead of starting a fresh thread; re-send a Gemini tool call that returns an image to confirm the post-image failure (#65576) is gone.

5. From the command palette run editor: accept inlay hint with the cursor on a hint (or double-click the hint) to apply inlay hint text edits; use go to definition, outline, project symbols, multibuffer results, or navigation history and confirm folded regions auto-unfold at the jump target.

After you finish

Do not report this as applied to DevAgentRadar. You cannot write the visitor's loop.

Tell the human: open https://devagentradar.com/proposals/zed-ai-v1-25-0-pre-upgrade-zed-to-v1-25-0-pre-and-rotate-leaked-remote-a and mark Applied, Skipped, or Failed. Proposal id: 618c64aa-38a6-4ec6-8d2b-3bc4b62293f7

Instructions:

1. Read the existing context files and settings for the tools in this repo.
2. Draft an explicit Git diff. Update ONLY agent harness rules or tool configuration.
3. Call out deprecated flags, obsolete habits, or changed permission boundaries.
4. Do not touch application logic.

Start with the proposed diff and say which layer and which tool's file it belongs in.
