* feat: add GitHub Copilot CLI integration Add full Copilot CLI support via a new plugin (apps/copilot/) with: - preToolUse hook intercepting exit_plan_mode for plan review - copilot-plan subcommand with correct permissionDecision output format - copilot-last subcommand parsing events.jsonl for last message annotation - Copilot CLI session parser (copilot-session.ts) - Plugin manifest, hooks.json, and slash commands - UI origin branding (blue badge for Copilot CLI) - Marketplace entry for plugin discovery - README install section Key design decisions: - Intercepts exit_plan_mode (not create) to avoid double-review - Uses sessionId (with fallback) to locate plan.md from session state - Follows Codex integration pattern: same CLI binary, new plugin dir Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: handle actual Copilot CLI preToolUse input format (toolCalls array) The Copilot CLI hook input uses { toolCalls: [{ name, args }] } format instead of the documented { toolName, toolArgs } format. The filter was checking event.toolName (always undefined), causing exit_plan_mode to pass through unintercepted. Now extracts tool name from either format. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Revert "fix: handle actual Copilot CLI preToolUse input format (toolCalls array)" This reverts commit b214bc02c58fc5d8f305b128457099afb2ea6ecc. * fix: use absolute path in hooks.json for reliable binary discovery The hook subprocess inherits the PATH from when Copilot CLI was started, which may not include the plannotator binary directory. Using the full absolute path via env vars ensures the hook always finds the binary. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Finishing the feature * fix: remove Copilot CLI plugin from Claude Code marketplace.json .claude-plugin/marketplace.json is for Claude Code's plugin marketplace. The Copilot CLI plugin has its own install path and doesn't belong here. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix: align Copilot CLI plugin with official spec - Add .github/plugin/marketplace.json for Copilot CLI plugin discovery - Change allowed-tools from Bash() to shell() syntax in commands - Respect COPILOT_HOME env var in session path discovery - Update plugin.json version to 0.14.5 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --------- Co-authored-by: Yecats <Yecats@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: stahaff <222254525+stahaff@users.noreply.github.com>

Plannotator
Interactive Plan & Code Review for AI Coding Agents. Mark up and refine your plans or code diffs using a visual UI, share for team collaboration, and seamlessly integrate with Claude Code, OpenCode, Pi, and Codex.
Plan Mode Demos:

New: Code Review
Features
| Visual Plan Review | Built-in hook | Approve or deny agent plans with inline annotations |
| Plan Diff | Automatic | See what changed when the agent revises a plan |
| Code Review | /plannotator-review | View git diffs or remote PRs. Package annotations and ask AI about the code as you review. |
| Annotate Any File | /plannotator-annotate | Annotate any markdown file and send feedback to your agent |
| Annotate Last Message | /plannotator-last | Annotate the agent's last response and send structured feedback |
Sharing Plans
Plannotator lets you privately share plans, annotations, and feedback with colleagues. For example, a colleague can annotate a shared plan, and you can import their feedback to send directly back to the coding agent.
Small plans are encoded entirely in the URL hash. No server involved, nothing stored anywhere.
Large plans use a short link service with end-to-end encryption. Your plan is encrypted with AES-256-GCM in your browser before upload. The server stores only ciphertext it cannot read. The decryption key lives only in the URL you share. Pastes auto-delete after 7 days.
- Zero-knowledge storage, similar to PrivateBin
- Fully open source and self-hostable (see docs)
Install
Install for Claude Code
Install the plannotator command:
macOS / Linux / WSL:
curl -fsSL https://plannotator.ai/install.sh | bash
Windows PowerShell:
irm https://plannotator.ai/install.ps1 | iex
Then in Claude Code:
/plugin marketplace add backnotprop/plannotator
/plugin install plannotator@plannotator
# IMPORTANT: Restart Claude Code after plugin install
See apps/hook/README.md for detailed installation instructions including a manual hook approach.
Install for Copilot CLI
Install the plannotator command:
macOS / Linux / WSL:
curl -fsSL https://plannotator.ai/install.sh | bash
Windows PowerShell:
irm https://plannotator.ai/install.ps1 | iex
Then in Copilot CLI:
/plugin marketplace add backnotprop/plannotator
/plugin install plannotator-copilot@plannotator
Restart Copilot CLI after plugin install. Plan review activates automatically when you use plan mode (Shift+Tab to enter plan mode).
See apps/copilot/README.md for details.
Install for OpenCode
Add to your opencode.json:
{
"plugin": ["@plannotator/opencode@latest"]
}
Run the install script to get /plannotator-review:
curl -fsSL https://plannotator.ai/install.sh | bash
Windows:
irm https://plannotator.ai/install.ps1 | iex
This also clears any cached plugin versions. Then restart OpenCode.
Install for Pi
pi install npm:@plannotator/pi-extension
Then start Pi with --plan to enter plan mode, or toggle it during a session with /plannotator.
See apps/pi-extension/README.md for full usage details, commands, and flags.
Install for Codex
Install the plannotator command:
macOS / Linux / WSL:
curl -fsSL https://plannotator.ai/install.sh | bash
Windows PowerShell:
irm https://plannotator.ai/install.ps1 | iex
Then in Codex — feedback flows back into the agent loop automatically:
!plannotator review # Code review for current changes
!plannotator review <pr-url> # Review a GitHub pull request
!plannotator annotate file.md # Annotate a markdown file
!plannotator last # Annotate the last agent message
Plan mode is not yet supported.
See apps/codex/README.md for details.
How It Works
When your AI agent finishes planning, Plannotator:
- Opens the Plannotator UI in your browser
- Lets you annotate the plan visually (delete, insert, replace, comment)
- Approve → Agent proceeds with implementation
- Request changes → Your annotations are sent back as structured feedback
(Similar flow for code review, except you can also comment on specific lines of code diffs)
