webhook-subscriptions

webhook-subscriptions is a skill for Claude Code, Codex from graniet/kheish. It costs 24 tokens per session (1,603 once invoked), scanned A, original, Apache-2.0.

A workflow for creating and managing webhooks, URLs that receive event notifications from external services and can trigger agent runs.

In plain words
What is it for?
Use it with services such as GitHub, GitLab, Stripe, CI/CD systems, IoT sensors, or monitoring tools, subject to the deployment tooling available.
Why use it?
It connects outside events to automated agent work instead of requiring someone to start each run manually.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kheish Compatibility

This skill is repo-local and stays inactive until explicitly activated.

When the original instructions refer to legacy tool names, use these Kheish mappings:

  • terminal => bash
  • web_extract => web_fetch, plus web_search when discovery is needed
  • search_files => grep_search and glob_search
  • browser_* tools require a browser-capable surfaced tool or MCP; if none is available, use the closest available surface and say so explicitly

When the instructions mention local helper files, resolve them from ${KHEISH_SKILL_DIR}.

Kheish does not currently ship a dedicated webhook subscription CLI. In the examples below, webhook-manager and gateway-manager are placeholders for your deployment tooling around daemon connector config, ingress routing, and lifecycle management.

Webhook Subscriptions

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

Setup (Required First)

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

webhook-manager list

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

Option 1: Setup wizard

gateway-manager setup

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

Option 2: Manual config

Add to ~/.kheish/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 ~/.kheish/.env:

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

After configuration, start (or restart) the gateway:

gateway-manager run
# Or if using systemd:
systemctl --user restart kheish-daemon

Verify it's running:

curl http://localhost:8644/health

Commands

All management is via the webhook-manager CLI command:

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.
