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

outpost 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 6d 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.

Hookdeck Outpost

Outpost is open-source infrastructure for delivering events to user-preferred destinations: Webhooks (HTTP), SQS, RabbitMQ, Pub/Sub, EventBridge, Kafka, and more. Apache 2.0 licensed, available as managed by Hookdeck or self-hosted.

When to Use Outpost

  • You're building a SaaS or API platform and need to send webhooks to your users
  • You need multi-destination support beyond HTTP webhooks (SQS, RabbitMQ, Pub/Sub, EventBridge, Kafka)
  • You want self-hostable webhook delivery infrastructure
  • You need multi-tenant support with per-user observability
  • You want to offer your customers reliable, retryable event delivery

Quick Start

Managed (Hookdeck)

The fastest way to get started — Hookdeck hosts and operates Outpost for you:

  1. Sign up at hookdeck.com
  2. See the Send Webhooks quickstart

Self-Hosted

Run Outpost on your own infrastructure:

  1. See the Outpost documentation
  2. Clone from GitHub

Supported Destinations

Webhooks HTTP/HTTPS
Amazon SQS AWS SQS
RabbitMQ AMQP
Google Pub/Sub gRPC
Amazon EventBridge AWS EventBridge
Apache Kafka Kafka protocol

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.
