Listspace for coding agents

The pieces that let an agent use a Listspace board as its project memory. This folder is public as github.com/listspace/agent, and the CLI is on npm as listspace. Install and sign in with:

npx listspace login     # paste a personal token from Listspace: Settings > API
npx listspace boards

Editing the skill

Edit skills/listspace/ only, then run:

node agent/scripts/sync-skill.mjs
node agent/scripts/check-agent.mjs

The plugin gets a real copy, not a symlink, so the plugin folder still works when it is copied or downloaded on its own. CI fails when the two differ. Keep SKILL.md short: steps and rules there, detail in reference/.

One version runs through cli/package.json, cli/src/version.ts, plugin.json and the skill's metadata.version; the check fails when they differ.

Try it locally

The CLI

cd agent/cli
npm ci
npm run build
node dist/listspace.mjs login            # paste a token from Listspace: Settings > API
node dist/listspace.mjs whoami
node dist/listspace.mjs session "<board title or id>"
node dist/listspace.mjs add "<board>" ideas "Try dark mode" --description "Seen in **settings**"

npm link in agent/cli puts listspace on the PATH. LISTSPACE_TOKEN overrides the saved token for one run, and LISTSPACE_API_URL points the CLI at another server. Every command takes --json. The token is saved in the OS config directory (%APPDATA%\listspace on Windows, ~/Library/Application Support/listspace on macOS, ~/.config/listspace elsewhere) as credentials.json, mode 600.

Tests: npm test (node:test with a fake fetch, no network). npm run typecheck runs the strict type check.

The skill on its own

Any agent that reads Agent Skills:

npx skills add ./agent -s listspace     # the skills CLI reads skills/ in a local folder

or copy agent/skills/listspace to ~/.claude/skills/listspace for Claude Code. Connect the MCP server separately (claude mcp add --transport http listspace https://mcp.listspace.app), or use the CLI above.

The Claude Code plugin

For one session:

claude --plugin-dir ./agent/claude-code-plugin

Or as a local marketplace, which keeps it installed:

claude plugin marketplace add ./agent
claude plugin install listspace@listspace

Then run /mcp, pick the listspace server and sign in (OAuth through Listspace). The skill shows up as /listspace:listspace and Claude loads it on its own when the project has a board. claude plugin validate ./agent/claude-code-plugin checks the manifest.

If you already added the Listspace MCP server yourself, Claude Code may show both; remove one.

What is left out, and why

• comment and attach: the API has them now (POST /v1/items/:id/comments, POST /v1/items/:id/attachments, MCP add_comment, attach_file), but the CLI does not yet. Agents on the CLI log progress in a Project info item (the skill says so).
• Device pairing for login: comes with sign-up (PR 9). login already separates "how the token is obtained" from saving it; a TODO in cli/src/cli.ts marks where pairing goes. --token and a piped token stay for scripts.
• A token in the plugin: .mcp.json has no headers on purpose. A token would ship to every user; sign-in through /mcp is per user. The check script refuses headers there.
• The CLI inside the plugin (bin/): left out, because claude.ai and Cowork do not install plugins with a top-level bin/ and the MCP server covers Claude Code.

Publishing

1. Skill via npx skills add: published. The public repository listspace/agent holds this folder at its root, so npx skills add listspace/agent works.
2. CLI on npm: published as the unscoped listspace (0.1.0). To release a new version: bump the one version (see "Editing the skill"), check the package contents with npm pack --dry-run, then npm publish from agent/cli with an npm account with 2FA. prepublishOnly runs the type check, tests and build.
3. Claude Code plugin: the public repo doubles as a marketplace (.claude-plugin/marketplace.json), so users run /plugin marketplace add listspace/agent and /plugin install listspace@listspace. Listing in Anthropic's plugin directory is a separate submission; the owner decides on it, with privacy policy and terms URLs for that listing.
