Anno tools (6, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • html_review_claim_handoff

    The receiving agent turn must call this first to provide a durable receipt that the exact Anno generation request reached the current session. Idempotent for the active handoff.

  • html_review_get_session

    Read the current session status, output paths, edit counts, and complete annotation payload. Use after the user finishes browser review or when resolving pending free-form annotations.

  • html_review_list_sessions

    List recent local HTML review sessions with concise status and output metadata.

  • html_review_mark_handoff_sent

    Record that the host accepted an Anno follow-up message for transport. This is not an agent receipt; the receiving turn must still call html_review_claim_handoff.

  • html_review_register_final

    Register a fully resolved HTML file as the final output for a review session. Copies it to a new non-overwriting output path, preserves the source, and marks the session resolved. Use only after the agent has applied and visually verified remaining free-form annotations.

  • html_review_start_sessionwrite action

    Create an isolated local review session for an HTML file. Copies the source into session storage, starts a browser editor URL, and chooses a non-overwriting output path. Returns the session id and review URL.

Install Anno in Claude Code, Cursor or VS Code

Runs npx -y @philmingdao/anno on your machine. Read the scan report first; the gateway never runs local packages.

Anno

Anno is a local-first HTML review workspace for AI coding agents. It opens an isolated copy of a local HTML file in a browser, supports direct text and formatting edits, element comments, area annotations, and slide-aware review, then returns a durable handoff that an agent can claim and resolve into a verified standalone HTML file.

The repository contains one shared MCP server and host-neutral skill, native plugin manifests where a host supports them, and copy-ready MCP templates for Cursor, Google Antigravity, Windsurf, GitHub Copilot, and Meta Muse Code. DeepSeek Harness support is maintained separately in philmingdao/anno-dsh-native, an in-process native plug-in built with DeepSeek Harness; Muse Code support remains experimental.

Highlights

  • Local-only HTTP editor bound to 127.0.0.1
  • Source files are never overwritten
  • Direct text, typography, color, position, page-note, element, and area editing
  • Durable, idempotent agent handoffs
  • Legacy compatibility with existing needs_codex sessions
  • Shared MCP and SKILL.md implementation across supported hosts
  • Simplified Chinese and English UI, light and dark themes

Screenshots

The review editor opens an isolated copy of your HTML in the browser. Edit text and styles directly, leave element or area comments, and hand the collected changes back to the agent in one click.

Requirements

  • Node.js 22 or newer
  • A host that supports local stdio MCP servers and can access local files
  • A browser for the review editor

Supported agent tools

Codex, Claude Code, WorkBuddy, and CodeBuddy use packaged plugin manifests. Cursor, Google Antigravity, Windsurf, GitHub Copilot CLI/Chat, and Muse Code connect to the same local stdio MCP server through host-specific configuration templates. DeepSeek Harness uses the independent native anno-dsh-native repository, which integrates directly with the DSH profile, tool registry, and agent lifecycle without an MCP bridge.

See Agent tool integrations for copy-ready configuration and host limitations.

One-command install

No clone or build is required. The installer detects available agent tools, lets you choose them interactively, merges only the anno entry into existing JSON/JSONC configuration, installs the shared skill, creates a timestamped backup before changes, and runs an MCP handshake.
