Can I use Coauthor Brief with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works

Fetched the raw SKILL.md via gh API (rate-limited on anon curl) and verified every relative reference resolves in the repo tree: sibling skills (checkpoint, commit, capture-environment, audit-reproducibility, compress-session) and rules files (meta-governance, confidential-data, replication-protocol) all exist. Pure prompt skill using only Read/Write/Glob/Grep/Bash — no external CLI, no exfiltration/hidden-instruction/base64/referral patterns. Trigger phrasings tested (should load): "write a coauthor brief for Sarah before I send her the repo", "bring my collaborator up to speed on what changed since last week", "onboard a new RA with the reproduce and data-access steps"; should NOT load: "write a commit message for these changes" (that's /commit), "checkpoint where I am so I can resume tomorrow" (that's /checkpoint) — all 5 judged correctly.

What Coauthor Brief does

A slash-command prompt skill that writes a Markdown handoff brief for a co-author or your future self on another machine: what changed since the last brief (git delta grouped by area), the state of each artifact, open questions, local reproduce steps, and restricted-data access process. Triggers on phrasings like "coauthor brief", "handoff brief", "bring my coauthor up to speed", or "onboard a collaborator". Slash-command only (disable-model-invocation), scoped to distinguish itself from commit/checkpoint.

How to install Coauthor Brief

Part of the claude-code-my-workflow suite. Clone and copy the skills tree into your project: `git clone https://github.com/pedrohcgs/claude-code-my-workflow && cp -r claude-code-my-workflow/.claude/skills claude-code-my-workflow/.claude/rules your-project/.claude/`. Then invoke `/coauthor-brief`. Copying only the coauthor-brief folder works but breaks the cross-reference links to sibling skills and rules.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
