Install the Update Skills skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/nanocoai/nanoclaw --skill update-skills

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/nanocoai/nanoclaw.git /tmp/nanoclaw
mkdir -p ~/.claude/skills
cp -R /tmp/nanoclaw/.claude/skills/update-skills ~/.claude/skills/update-skills

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

Until it is used, update-skills costs about 25× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 64 skills from nanocoai/nanoclaw would load 3,369 tokens of descriptions. Skills vs MCP study

  1. add-anydocnanocoai/nanoclaw

    Add local office-document-to-Markdown conversion to NanoClaw agent containers with the pinned Firecrawl AnyDoc CLI. Use when agents need to read attached Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, or text-based PDF files without uploading them to a hosted parser.

  2. add-atomic-chat-toolnanocoai/nanoclaw

    Add Atomic Chat MCP server so the container agent can call local models served by the Atomic Chat desktop app via its OpenAI-compatible API.

  3. add-clidashnanocoai/nanoclaw

    Add clidash — a zero-dependency, read-only web dashboard that derives its tabs and tables at runtime from any CLI that lists resources as JSON. Ships pre-wired for NanoClaw's ncl CLI (agent groups, sessions, channels, users, roles), plus message-activity charts, a log tail, and a read-only file viewer for group skills/CLAUDE.md/profiles.

  4. add-codexnanocoai/nanoclaw

    Use Codex (OpenAI's codex app-server) as a full agent provider — planning, tool orchestration, MCP tools, server-side history, session resume — alongside or instead of Claude. ChatGPT subscription or OpenAI API key, vault-only via the selected gateway. Per-group via `ncl groups config update --provider codex`. Distinct from using OpenAI as an MCP tool (where Claude remains the planner).

  5. add-cursornanocoai/nanoclaw

    Use Cursor (local Agent SDK) as a full agent provider — planning, tool orchestration, MCP tools, session resume — alongside or instead of Claude. Cursor-account sign-in or API key, held by the credential gateway. Per-group via `ncl groups config update --provider cursor`. Distinct from using Cursor as a cloud agent (those run on Cursor VMs and are not this provider).
