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

add-webhook 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 23d 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.

What it actually says

Skills: webhooks, app-auth

Read the named skills from this plugin before following the workflow. Use only the relevant ones; commands guide work rather than grant permissions.

  1. Verify current topic/config and framework before creating files.
  2. Use supported authentication, raw-body verification where custom code is needed, and durable enqueue before acknowledgement.
  3. Add shop isolation, deduplication, retry/recovery and real privacy cleanup where applicable.
  4. Test forged/altered body, duplicate event and failed queue; verify actual dev-store delivery if authorized.

Beginner-friendly delivery

Explain unfamiliar terms once, recommend one next action and state the expected result before executing. Preserve unrelated work. Never read credential caches or print secrets. Paid runs, store writes, scope/access expansion, charges, deployment and submission require explicit task-specific authorization.

Completion evidence

Separate handler tests, configuration registration and observed real event delivery. Show actual results, the remaining blocker and the next step; do not print anticipated success checkmarks. If the host cannot register commands, invoke the listed skills in ordinary language instead.

Changes

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.
