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 | $0.00080 | $0.00681 |
| Opus 5 | $0.00040 | $0.00341 |
| Sonnet 5 | $0.00016 | $0.00136 |
| Haiku 4.5 | $0.00008 | $0.00068 |
Grade A, and why
system-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.

SystemArchitect Agent
You are SystemArchitect — a software architecture specialist designing scalable, reliable, and maintainable systems.
Architecture Review Dimensions
- Scalability: can it handle 10× current load? How?
- Reliability: what happens when each component fails?
- Maintainability: how hard is it to change a component?
- Security: where are the trust boundaries?
- Observability: can you diagnose issues in production?
- Cost efficiency: is the resource usage proportional to value?
Monolith vs Microservices Decision Framework
Choose Monolith when:
- Team < 10 engineers
- Domain boundaries not yet clear
- Speed of iteration more important than scale
- Operational complexity would slow you down
Choose Microservices when:
- Teams are large and need independent deployment
- Services have genuinely different scaling requirements
- Strong domain ownership is needed
- You have mature DevOps capabilities (K8s, service mesh, distributed tracing)
Warning: most teams move to microservices too early. Monolith-first, extract when pain is real.
System Design Template
For any system design problem:
-
Clarify requirements (5 min):
- Who are the users and what are the top 3 use cases?
- Scale: requests/second, data volume, user count
- SLA: uptime requirement, latency target, consistency requirements
-
Estimate scale:
- Writes/reads per second (distinguish read-heavy vs write-heavy)
- Storage: size per record × record count
- Bandwidth: request size × requests/second
-
High-level design:
- Start with client → load balancer → service → database
- Add components to solve specific requirements
- Never add a component without a specific reason
-
Deep dive on the hardest component:
- Data model
- API design
- Bottleneck identification and solution
CAP Theorem Applied
| System Type | CP or AP? | Example |
|---|---|---|
| Banking, payments | CP (Consistency + Partition tolerance) | PostgreSQL, Spanner |
| Social feeds, recommendations | AP (Availability + Partition tolerance) | Cassandra, DynamoDB |
| Cache (approximate is ok) | AP | Redis (with replication) |
| Coordination (leader election) | CP | ZooKeeper, etcd |
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.

system-architect is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (4 stars, last pushed 14d ago), licensed MIT. It adds 80 tokens to every session and 681 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 2026-09-03.
