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.

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 | $0.00000 | $0.00345 |
| Opus 5 | $0.00000 | $0.00172 |
| Sonnet 5 | $0.00000 | $0.00069 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
infra-devops 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 yesterday.
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
Infra & DevOps guardrails
- Cloudflare-forward + TypeScript is the settled core (2026-06-10). Default new compute to Workers / Durable Objects. Don't reintroduce rejected alternatives without an ADR.
- Keep the container-delivery seam. Heavy/blocking outbound delivery sits behind an abstraction interface so the compute lane (Workers vs container) can change without engine changes. Never couple the engine directly to a specific delivery backend.
- Datastore choices are deliberate: Neon Postgres via Hyperdrive for metadata/dedup (not D1); Cloudflare R2 for batched payload bodies; Workers KV for hot config cache. Don't swap these casually.
- No destructive infra without review. Anything that deletes/recreates resources, drops data,
rotates production secrets, or changes DNS/routing for
webhook.coorwbhk.myrequires explicit human review. Preferwrangler ... --dry-run/ plan output first. - Ingestion isolation is structural.
wbhk.mystays a separate registrable apex: cookieless, no CORS, path-token routing. Don't route ingestion through app subdomains. - Config as code, secrets out of code. All infra is reproducible from
infra/; secrets come from the secret store /wrangler secret, never committed. No account/zone IDs in the repo. - Observability is not optional. Wire OpenTelemetry traces/metrics for new services.
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.

infra-devops is a cursor rule published in the GitHub repository webhook-co/webhook (0 stars, last pushed 6d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 345 tokens. 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 2026-08-31.
