* feat(gemini): add Gemini CLI plan review integration Adds a new `apps/gemini-hook/` adapter that enables Plannotator plan review for Gemini CLI users via the BeforeTool hook system. The adapter reads the plan file from disk (Gemini provides a path, not inline content), delegates to the shared @plannotator/server for the browser-based review UI, and translates the decision back into Gemini's hook output format. Requires an upstream fix (google-gemini/gemini-cli#21802) that makes `decision = "allow"` user policies work for exit_plan_mode, allowing hooks to replace the built-in TUI approval dialog. Includes: - apps/gemini-hook/server/index.ts — stdin/stdout adapter - apps/gemini-hook/hooks/ — policy TOML + settings snippet - scripts/install.sh — Gemini binary download, policy install, settings config For provenance purposes, this commit was AI assisted. * refactor(gemini): use single binary with auto-detection instead of separate app Removes apps/gemini-hook/ — the plannotator binary now auto-detects Gemini CLI from stdin (plan_path = file on disk) vs Claude Code (plan = inline content) and branches input parsing + output formatting. Config fixtures live in apps/gemini/ (policy TOML + settings snippet). Install script gates on ~/.gemini existing so Claude-only users are unaffected. For provenance purposes, this commit was AI assisted. * test(gemini): add manual sandbox script for Gemini CLI integration Three modes: - --simulate: pipes BeforeTool JSON to hook, tests approve/deny output - (default): runs local patched Gemini build - --nightly: installs Gemini nightly and runs it Backs up and restores ~/.gemini config on exit. For provenance purposes, this commit was AI assisted. * feat(gemini): add slash commands, marketing tab, and docs for Gemini CLI - Add /plannotator-review and /plannotator-annotate slash commands (.toml) - Install Gemini slash commands in all three install scripts (sh, ps1, cmd) - Add Gemini tab to marketing landing page with icon - Add Gemini CLI to top-level README install section - Create apps/gemini/README.md with full setup and usage docs - Remove stale dev:gemini script and regenerate bun.lock For provenance purposes, this commit was AI assisted. * fix(gemini): merge hook into existing settings.json instead of printing instructions When ~/.gemini/settings.json already exists, use node to JSON-merge the BeforeTool hook config rather than asking the user to do it manually. Falls back to instructions only if node is unavailable. For provenance purposes, this commit was AI assisted. * fix(gemini): handle plan_filename rename and fix scoping bug Gemini CLI nightly renamed plan_path to plan_filename in exit_plan_mode. Accept both field names for forward/backward compatibility. Reconstruct full plan path from transcript_path + session_id + plans/ + filename. Also hoist planFilename variable out of try block so it's accessible in the deny output path (was causing ReferenceError). For provenance purposes, this commit was AI assisted. * fix(gemini): dim approve button when annotations exist for Gemini CLI Gemini's hook runner ignores systemMessage on the allow path, so approve-with-feedback is silently dropped — same limitation as Claude Code. Extend the existing UI gate to also apply for gemini-cli origin. For provenance purposes, this commit was AI assisted. * fix(gemini): add AGENT_CONFIG entry and fix sandbox simulate mode Register "gemini-cli" in AGENT_CONFIG so the UI shows "Gemini CLI" with proper badge styling instead of generic "Coding Agent" fallback. Update sandbox simulate mode to match production input format: use plan_filename instead of plan_path, include transcript_path, and simulate the Gemini directory structure for path reconstruction. For provenance purposes, this commit was AI assisted.

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 Gemini 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
The installer auto-detects Gemini CLI (checks for ~/.gemini) and configures the plan review hook and policy. It also installs /plannotator-review and /plannotator-annotate slash commands.
Then in Gemini CLI:
/plan # Enter plan mode — plans open in your browser
/plannotator-review # Code review for current changes
/plannotator-review <pr-url> # Review a GitHub pull request
/plannotator-annotate <file.md> # Annotate a markdown file
Requires Gemini CLI 0.36.0 or later.
See apps/gemini/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)
