Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.00720 |
| Opus 5 | $0.00027 | $0.00360 |
| Sonnet 5 | $0.00011 | $0.00144 |
| Haiku 4.5 | $0.00005 | $0.00072 |
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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- Sign up at hookdeck.com
- See the Send Webhooks quickstart
Self-Hosted
Run Outpost on your own infrastructure:
- See the Outpost documentation
- Clone from GitHub
Supported Destinations
| Destination | Protocol |
|---|---|
| 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.

outpost is a skill published in the GitHub repository hookdeck/webhook-skills (84 stars, last pushed 6d ago), licensed MIT. It adds 54 tokens to every session and 720 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
