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 | $0.00027 | $0.00237 |
| Opus 5 | $0.00014 | $0.00118 |
| Sonnet 5 | $0.00005 | $0.00047 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
symfony:symfony-cache 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 5d 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.
This is a copy
86% identical to symfony:messenger-retry-failures — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Symfony Cache (Symfony)
Use when
- Implementing asynchronous workflows with Messenger/Scheduler/Cache.
- Stabilizing retries and failure transports.
Default workflow
- Define async contract and delivery semantics.
- Implement idempotent handlers and routing strategy.
- Configure retries, failure transport, and observability.
- Validate success/failure replay scenarios.
Guardrails
- Assume at-least-once delivery, not exactly-once.
- Keep handlers deterministic and side-effect aware.
- Surface poison-message handling strategy.
Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.
Output contract
- Async config/handlers updated.
- Retry/failure policy decisions.
- Operational validation evidence.

What ships with it
1 file 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.

symfony:symfony-cache is a skill published in the GitHub repository dev-toolings/superpowers-symfony (208 stars, last pushed 4d ago), licensed MIT. It adds 27 tokens to every session and 237 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to symfony:messenger-retry-failures, differing in 6 lines, and is treated as a copy.
Other skills, from other repositories
application
Use when creating application layer artifacts for a NestJS bounded context — use cases, CQRS command/query handlers, DTOs, ports (cross-module interfaces), application services, or read model projections. Supports three patterns: plain UseCase (A), CQRS native (B), and Handler-as-Orchestrator (C).
domain
Use when creating domain layer artifacts for a NestJS bounded context — entities (AggregateRoot), value objects, domain events, repository interfaces, domain services, validators, or data builders. Covers Hexagonal Architecture + DDD patterns with NestJS CQRS native event support.
event-listeners
Use when creating event listeners that react to domain events — same-BC side effects (projections, audit, cache), cross-BC reactions (another bounded context consuming events), or bridge listeners (WebSocket broadcast, RabbitMQ publish, email). Covers listener taxonomy, placement rules, Strategy+Gateway pattern for…
infrastructure
Use when creating infrastructure layer artifacts for a NestJS bounded context — Prisma repositories, in-memory repositories (testing), model mappers, NestJS module wiring, adapters (port implementations), or event handler infrastructure. Repository is pure persistence with no event dispatch.
review-subdomain
Reviews a NestJS bounded context implementation for Hexagonal Architecture + DDD + CQRS compliance. Checks 6 dimensions — domain purity, application patterns, infrastructure isolation, presentation concerns, testing coverage, and module organization. Produces a structured Pass/Warning/Fail report.
presentation
Use when creating presentation layer artifacts for a NestJS bounded context — REST controllers, request DTOs with class-validator, Swagger decorators, custom validators, error filters, or API documentation. Covers the HTTP boundary with proper validation and error mapping.
