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.
npx agentmods add instructions/hookdeck/webhook-skills/agents-mdgit clone --depth 1 https://github.com/hookdeck/webhook-skillsWhat 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 | $0.07872 | $0.07872 |
| Opus 5 | $0.03936 | $0.03936 |
| Sonnet 5 | $0.01574 | $0.01574 |
| Haiku 4.5 | $0.00787 | $0.00787 |
Grade B, and why
webhook-skills AGENTS.md scanned grade B 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 2d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

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.
- 2d ago First seen · 892 lines · 7,872 tokens per session scan B eeb0932afd01
webhook-skills AGENTS.md is an instructions file published in the GitHub repository hookdeck/webhook-skills (83 stars, last pushed 5d ago), licensed MIT. It adds 7,872 tokens to every session, about $0.0394 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
