webhook-subscriptions

webhook-subscriptions is a skill for Claude Code, Codex from braxtonROSE4/zorro-agent. It costs 29 tokens per session (1,423 once invoked), scanned A, original, MIT.

A tool for creating and managing webhooks, which are URLs that receive event notifications from outside services and can start an agent run automatically.

In plain words
What is it for?
It helps set up subscriptions, configure the webhook gateway, verify its health, and connect external events from services or devices to agent workflows.
Why use it?
It removes the need for someone to start an agent manually whenever GitHub, Stripe, a CI system, or another connected service produces an event.

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

webhook-subscriptions scanned grade A with 1 finding 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 yesterday.

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.

Webhook Subscriptions

Create dynamic webhook subscriptions so external services (GitHub, GitLab, Stripe, CI/CD, IoT sensors, monitoring tools) can trigger Zorro Agent runs by POSTing events to a URL.

Setup (Required First)

The webhook platform must be enabled before subscriptions can be created. Check with:

zorro webhook list

If it says "Webhook platform is not enabled", set it up:

Option 1: Setup wizard

zorro gateway setup

Follow the prompts to enable webhooks, set the port, and set a global HMAC secret.

Option 2: Manual config

Add to ~/.zorro/config.yaml:

platforms:
  webhook:
    enabled: true
    extra:
      host: "0.0.0.0"
      port: 8644
      secret: "generate-a-strong-secret-here"

Option 3: Environment variables

Add to ~/.zorro/.env:

WEBHOOK_ENABLED=true
WEBHOOK_PORT=8644
WEBHOOK_SECRET=generate-a-strong-secret-here

After configuration, start (or restart) the gateway:

zorro gateway run
# Or if using systemd:
systemctl --user restart zorro-gateway

Verify it's running:

curl http://localhost:8644/health

Commands

All management is via the zorro webhook CLI command:

Create a subscription

zorro webhook subscribe <name> \
  --prompt "Prompt template with {payload.fields}" \
  --events "event1,event2" \
  --description "What this does" \
  --skills "skill1,skill2" \
  --deliver telegram \
  --deliver-chat-id "12345" \
  --secret "optional-custom-secret"

Returns the webhook URL and HMAC secret. The user configures their service to POST to that URL.

List subscriptions

zorro webhook list

Remove a subscription

zorro webhook remove <name>

Test a subscription

zorro webhook test <name>
zorro webhook test <name> --payload '{"key": "value"}'

Prompt Templates

Prompts support {dot.notation} for accessing nested payload fields:

  • {issue.title} — GitHub issue title
  • {pull_request.user.login} — PR author
  • {data.object.amount} — Stripe payment amount
  • {sensor.temperature} — IoT sensor reading

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.
