watcher-creator

watcher-creator is a skill for Claude Code, Codex from asheshgoplani/agent-deck. It costs 87 tokens per session (2,740 once invoked), scanned A, original, MIT.

A guided setup for watchers, which listen for events from services such as GitHub, Slack, Gmail, webhooks, or ntfy and send them to an agent-deck conductor.

In plain words
What is it for?
Use it to create a watcher, prepare its configuration files, and get the command needed to connect an event source to agent-deck.
Why use it?
It removes the guesswork from choosing a connection type and collecting the settings needed to make event routing work.

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.

Security

Grade A, and why

watcher-creator 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 5d 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.

Watcher Creator

Overview

This skill guides users through setting up a new agent-deck watcher from scratch. A watcher listens for incoming events (webhooks, ntfy notifications, GitHub events, Slack messages, or Gmail messages) and routes them to the appropriate conductor session. The skill asks clarifying questions, collects required settings, and emits the exact CLI command and configuration files to create a working watcher.

When to use

Invoke this skill when a user says things like:

  • "I want to set up a new watcher"
  • "How do I connect GitHub webhooks to agent-deck?"
  • "Help me route Slack messages to a conductor"
  • "Create a watcher for my Gmail inbox"
  • "I need agent-deck to listen for ntfy notifications"

Step-by-step conversational flow

Step 1: Choose adapter type

Ask the user which source they want to receive events from. Present the five options:

  1. webhook - Generic HTTP POST webhook (any service that can send HTTP)
  2. ntfy - ntfy.sh push notification topic
  3. github - GitHub repository webhooks (issues, PRs, pushes)
  4. slack - Slack messages via a Cloudflare Worker bridge to ntfy
  5. gmail - Gmail inbox via Google Cloud Pub/Sub watch

Step 2: Gather required settings for the chosen type

Once the user picks a type, ask for the settings specific to that adapter (see the per-type sections below). Ask for each required setting one at a time to avoid overwhelming the user.

Also ask:

  • Watcher name: A short lowercase identifier (e.g., my-webhook, github-alerts). This becomes the directory name under the effective watcher data dir (${XDG_DATA_HOME:-$HOME/.local/share}/agent-deck/watcher for new users; legacy ~/.agent-deck/watcher remains in use when existing watcher state is present).
  • Conductor: Which conductor session this watcher should route events to by default (the conductor field in clients.json).
  • Group: Which group the conductor session lives in (the group field in clients.json).

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.
