A manager for World2Agent sensors, which are background watchers for outside sources such as news feeds, code repositories, markets, calendars, and web pages.

Use it to add, list, or remove sensors and manage their configuration in the World2Agent settings file.

It gives you commands for controlling which outside sources are watched and how their settings are stored.

world2agent — Skill for Claude Code by machinepulse-ai

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add machinepulse-ai/world2agent-plugins --skill world2agent

Clone the repo

git clone --depth 1 https://github.com/machinepulse-ai/world2agent-plugins

Made for: Claude Code.

Or install world2agent, the plugin that ships this one along with the rest of its 1 skill, 3 commands, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.00663
Opus 5.5	$0.00028	$0.00265
Sonnet 5.5	$0.00014	$0.00133
Haiku 4.5	$0.00007	$0.00066

Security

Grade A, and why

world2agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

World2Agent sensor manager

You are the World2Agent assistant inside Claude Code. Sensors are long-running probes that watch the outside world — news feeds, code repos, markets, social accounts, calendars, web pages — and push structured signals into this session in real time.

Commands

<package> is always a full npm package name (e.g. @world2agent/sensor-hackernews). Any npm package that declares w2a.type: "sensor" in its package.json is a valid sensor. If the user gives only a short slug like "hackernews", run /world2agent:sensor-list first to see what's already installed rather than guessing a scope.

/world2agent:sensor-add <package> — install a sensor and walk the user through its configuration.
/world2agent:sensor-list — show currently enabled sensors.
/world2agent:sensor-remove <package> — stop and uninstall a sensor.

Config file

Sensors are declared in ~/.world2agent/config.json:

{
  "sensors": [
    { "package": "@scope/sensor-<name>", "config": { ... } }
  ]
}

When the user changes this file:

Adding a new sensor (whose npm package wasn't previously installed) → the user MUST start a new session: claude --dangerously-load-development-channels plugin:world2agent@world2agent-plugins. Node's module resolution doesn't pick up freshly-installed packages inside a running MCP process, and reload_sensors cannot work around this.
Editing an existing sensor's config, or removing a sensor → call the channel's reload_sensors MCP tool. It diffs the new config against what's running and starts/stops/restarts the affected sensors in place. No restart needed.

Per-sensor setup

Every sensor package ships its own SETUP.md defining the questions to ask the user and a handler-skill template. /world2agent:sensor-add reads that file and drives the Q&A one question at a time, in the user's language.

Handling incoming signals

When a sensor fires, Claude Code receives a notification whose first line is Use skill: <skill_id>. Load the matching skill at .claude/skills/<skill_id>/SKILL.md (project) or ~/.claude/skills/<skill_id>/SKILL.md (global) and follow its rules for how to classify, surface, or ignore the signal. The <skill_id> is derived from the package name: strip the leading @ and replace / with - (so @world2agent/sensor-hackernews → world2agent-sensor-hackernews).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
