It depends: minimal mode best matches the single-binary constraint, but it skips agent integration and is not equivalent to the full workflow.

• The README says a full install may contact GitHub beyond downloading the release, the optional Ataraxy-Labs/sem sidecar, and npm for Pi, extra skills, or the managed agent-terminal runtime.
• --minimal installs only the plannotator binary to ~/.local/bin and skips all skills, hooks, slash commands, and per-agent configuration, reducing the network and supply-chain surface.
• The project is a local, browser-based review surface, which is suitable when sensitive code should not be uploaded to a third-party service. However, that does not mean the installer and agent extensions are fully offline.

Minimal is viable if the team can configure agents separately and accepts core CLI functionality. Automatic Claude Code or Codex integration requires additional network-boundary review.

Yes, because the README explicitly provides Claude Code integration, plan review, and direct feedback return.

• The installer detects installed agents and configures hooks, skills, and slash commands; Claude Code still requires /plugin marketplace add backnotprop/plannotator and plugin installation.
• Plannotator is a local browser review surface. When the agent proposes a decision, plan, HTML artifact, or finishes work, the browser opens so annotations and feedback can be sent back.
• macOS, Linux, and WSL are covered by the shared installer command. Claude Code 2.1.287+ also supports a non-blocking flow where the decision arrives later as a message.

The README does not define the full compatibility boundary for older Claude Code versions or complex existing plugin configurations.

Yes, because Inbox is specifically presented as the unified review layer for multi-agent workflows.

• The README describes Plannotator Inbox as surfacing decisions, prototypes, variations, and plans, and says it works with all coding agents and personal assistants.
• Claude Code, Codex, Gemini CLI, and OpenCode all appear in the supported integration list, matching your four hosts.
• Integration differs by host: Claude Code and Gemini CLI use plugin or hook configuration, Codex uses a Stop hook, and OpenCode requires adding a plugin entry to opencode.json.
• The browser supports marking up, commenting, and sending feedback directly to the agent, reducing manual context transfer between terminals.

However, the README does not specify Inbox sorting, permissions, or team operating rules when many parallel items accumulate.

Yes, because it combines automatic Gemini CLI integration with visual annotation for plans, documents, and HTML artifacts.

• The README requires Gemini CLI 0.36.0+ and says the hook, policy, and slash commands are configured automatically, without an additional plugin command.
• The product description explicitly supports annotating plans, specifications, Markdown, HTML, and other interactive artifacts, as well as reviewing diffs and PRs.
• When the agent proposes a plan, HTML, or another artifact, the browser opens a review page where users can mark up, comment, and send feedback directly back.
• This is better than terminal-only text review when feedback must refer to visual structure, prototype interaction, or exact document locations.

The README does not clarify whether complex HTML retains all browser-runtime capabilities or define loading limits for very large documents.

It depends: Codex plan review is available, but native Windows has a weaker automation path than macOS, Linux, and WSL.

• The README says Codex plan review is enabled automatically through Codex’s experimental Stop hook, with support listed for macOS, Linux, and WSL.
• For native Windows, the README explicitly says Codex hooks are experimental and that the installer prints manual setup steps. Therefore, one-click automatic interception cannot be treated as guaranteed.
• The $plannotator-review, $plannotator-annotate, and $plannotator-last skills are included for Codex and can provide manual entry points.

If stable, no-manual-configuration interception on native Windows is a hard requirement, the available evidence is insufficient. If manual setup or WSL is acceptable, the fit is better.

It depends: the project explicitly includes Remote, SSH, and devcontainer scenarios, but network forwarding and access control between the remote agent and local browser remain prerequisites.

• The project insights list Remote, SSH, and devcontainer support within the intended feature scope.
• The README describes Plannotator as a local, browser-based review surface, with feedback returned through the host agent rather than automatically sending code to a cloud service.
• OpenCode requires adding "plugin": ["@plannotator/opencode@latest"] to opencode.json and restarting; that configuration must still be completed inside the remote environment.
• Link sharing, remote environments, and team collaboration introduce additional access-control and exposure risks and should not be treated exactly like single-machine local mode.

The fit is good if secure port forwarding and browser access can be established. The README does not specify forwarding commands, authentication, or the exact cross-container return topology.
