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 | $0.00058 | $0.01107 |
| Opus 5 | $0.00029 | $0.00553 |
| Sonnet 5 | $0.00012 | $0.00221 |
| Haiku 4.5 | $0.00006 | $0.00111 |
Grade A, and why
microservices-architect 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 8d 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.

Microservices Architect
Design production-ready microservices following Chris Richardson's Microservices Patterns with battle-tested principles for observability, reliability, and operability.
Overview
This skill guides you through microservices design with a focus on:
- Operability over cleverness — Systems we can run, trust, and evolve
- Observability first — If you can't see it, you can't trust it
- Async by default — Pub/sub patterns for resilience
- Explicit trust — Security and authorization built-in
Prime Directives (Non-Negotiables)
These are the rules every microservices design must follow. Exceptions require explicit justification.
| # | Directive | Meaning |
|---|---|---|
| 1 | Nothing unwatched exists | Ship observability with every feature. Know before customers. |
| 2 | Produce it → publish it. Consume it → consume all | Client-side filtering; wire is a consistent, schema'd data space |
| 3 | Pub/sub by default | Prefer event-driven; route through wireline formats quickly |
| 4 | Async by default; sync only when unavoidable | Pub/sub default; sync only for ACID/idempotency; isolate with feature flags |
| 5 | Trust must be explicit, scoped, and observable | Authenticate everything; authorize narrowly; emit signals on failures |
| 6 | Customers report it first = failure | Breaks happen; surprise is the failure. Detect before impact. |
| 7 | Observability over performance | Accept 20-30% overhead to eliminate blind spots |
| 8 | Siloing/bulkheading by design | Not using bulkheads = deployment choice. Not supporting them = architecture failure |
| 9 | Explicit Runtime Trust Profile | Time-bound, observable, revocable trust; policy via profiles, not patches |
| 10 | Operational knobs must be exposed | Expose the control, inputs, and effects. Operating > building |
Design Workflow
For every feature request, produce these outputs:
1. Design
- Message flows and sequence diagrams
- Schemas (events, commands, queries)
- Idempotency strategy
- Failure modes and recovery
What ships with it
4 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.

microservices-architect is a skill published in the GitHub repository OneDro1d/dark-factory (0 stars, last pushed today), licensed Apache-2.0. It adds 58 tokens to every session and 1,107 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 2026-09-01.
