What it does

Webhook Subscriptions is an agent skill from RedWoodOG/Hermes-Desktop. Create and manage webhook subscriptions for event-driven agent activation. Use when the user wants external services to trigger agent runs automatically.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Webhooks. It works with GitHub and Stripe.

When your agent uses it

  • The user wants external services to trigger agent runs automatically
  • Tasks that involve Webhooks

Example prompts

  • “/webhook-subscriptions”

Requirements

  • A credential in WEBHOOK_SECRET

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. hermes webhook subscribe writes to ~/.hermes/webhook_subscriptions.json
  2. The webhook adapter hot-reloads this file on each incoming request (mtime-gated, negligible overhead)
  3. When a POST arrives matching a route, the adapter formats the prompt and triggers an agent run
  4. The agent's response is delivered to the configured target (Telegram, Discord, GitHub comment, etc.)

What it can do on your machine

Read from SKILL.md and the folder at commit be46b39. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • WEBHOOK_SECRET

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Webhook Subscriptions loads about 1.4k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 414 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:42
    Add to `~/.hermes/.env`:

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 414 words (~1,423 tokens).

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