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 | $0.00090 | $0.01671 |
| Opus 5 | $0.00045 | $0.00835 |
| Sonnet 5 | $0.00018 | $0.00334 |
| Haiku 4.5 | $0.00009 | $0.00167 |
Grade A, and why
microservices 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Microservices and Distributed Systems
Microservices architecture splits a system into independently deployable services, each owning a specific business capability. This approach trades the simplicity of a monolith for flexibility in scaling, deployment, and technology choice - but only when the organizational and technical complexity is justified.
When to Use Microservices vs Monolith
There is no universal answer. The decision depends on team size, domain complexity, and operational maturity.
| Factor | Monolith Favored | Microservices Favored |
|---|---|---|
| Team size | Small team (fewer than 10 developers) | Multiple autonomous teams that need independent release cycles |
| Domain complexity | Simple or poorly understood domain | Well-understood domain with clear bounded contexts |
| Deployment cadence | Infrequent releases are acceptable | Different parts of the system need to ship at different speeds |
| Scaling needs | Uniform load across the application | Specific components need independent scaling |
| Operational maturity | Limited infrastructure automation | Mature CI/CD, monitoring, and container orchestration |
| Data isolation | Shared database is manageable | Services need independent data stores and schemas |
Start monolithic unless you have a clear reason not to. A well-structured modular monolith can be decomposed later. A premature microservices architecture adds distributed systems complexity without proportional benefit.
Service Decomposition Strategies
Deciding where to draw service boundaries is the hardest part. Get it wrong and you end up with a distributed monolith - all the costs of distribution with none of the benefits.
By Business Capability
Align services to what the organization does rather than how the software is structured. Each service maps to a business function: order management, inventory, billing, notifications. Services change when the business capability they represent changes.
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.

microservices is a skill published in the GitHub repository krzysztofsurdy/code-virtuoso (20 stars, last pushed 3mo ago), licensed MIT. It adds 90 tokens to every session and 1,671 once invoked, about $0.0005 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.
