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 5.1 | $0.00089 | $0.00543 |
| Opus 5 | $0.00044 | $0.00271 |
| Sonnet 5 | $0.00018 | $0.00109 |
| Haiku 4.5 | $0.00009 | $0.00054 |
Grade A, and why
rc-resilience 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 10d 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
Resiliência (event-driven) — guias por tarefa
Leia o guia da tarefa em references/ antes de agir. A premissa de todo guia aqui é a mesma:
falha de rede, entrega duplicada e consumidor morto não são exceção — são o caso normal
em sistemas distribuídos (Lambda, ECS, EventBridge, SQS). Projete para isso, não para o
caminho feliz.
Roteamento
| Tarefa | Guia |
|---|---|
| Idempotência, deduplicação e "exactly-once" | references/idempotency.md |
| Timeout, retry com backoff/jitter, circuit breaker, bulkhead | references/retries-timeouts.md |
| Poison message, DLQ, redrive, partial batch failure | references/dlq-poison.md |
Princípios sempre válidos
- Assuma at-least-once. Todo consumidor precisa ser idempotente — a mensagem duplicada vai chegar.
- Toda chamada remota tem timeout. E é retryable ou não — decida explicitamente, nunca por padrão implícito da lib.
- Falha precisa ter destino. DLQ, não log-e-segue. Se a falha não vai a lugar nenhum, ela vira perda silenciosa de dado.
- Retry sem backoff+jitter é ataque DDoS ao próprio sistema. Retry ingênuo em massa derruba o serviço que já está degradado.
Error Handling
Sem acesso à infra real (fila, tabela de idempotência, alarmes), projete a resiliência no
código e no IaC (Terraform/CDK/SAM) e diga explicitamente que a validação em runtime —
redrive de DLQ, teste de duplicata em ambiente real, disparo do circuit breaker sob carga —
ficou pendente. Para ver o efeito de uma falha em produção (logs, métricas, alarme de
profundidade de DLQ), use rc-observability.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rc-resilience is a skill published in the GitHub repository rodolfochicone/rc-project (19 stars, last pushed 1mo ago), licensed MIT. It adds 89 tokens to every session and 543 once invoked, about $0.0004 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 2026-08-30.
Other skills, from other repositories
opensrc
Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for"…
multi-tenant-architecture
Designs tenant isolation, hostname routing, custom-domain lifecycle, and plan limits on Cloudflare or Vercel. Use when asked to "isolate tenant data", "support custom domains", "build a white-label platform", or assess PSL registration. For general module structure use codebase-architecture; for SEO content use seo.
inbound-email
Handle email arriving at a ServiceNow instance — inbound email action ordering and stop-processing, the real syseventinemailaction column names, and reading sysemail when a message created no record.
mcp-tool-discovery
Find and call tools on this ServiceNow MCP server — the two meta-tools it starts with, why a missing session id makes every other tool unreachable, which queries actually match, and which advertised tools are not on the server at all.
background-script-execution
What actually happens when you call snowexecutescript — the Scripted REST endpoint Serac auto-deploys on first use, the scheduled-job fallback, what scheduledjobpending means, and how to get output back when the call comes home empty.
csdm-modeling
Pick the right ServiceNow service class under the Common Service Data Model — business service, service offering, application service, business application — and point the CMDB tools at it without creating the records CSDM tells customers to migrate away from.
