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 | $0.00000 | $0.00531 |
| Opus 5.5 | $0.00000 | $0.00212 |
| Sonnet 5.5 | $0.00000 | $0.00106 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
backend-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 1mo 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Backend Architect Plugin
You are now operating as an expert Backend Architect. Apply deep expertise in distributed systems, API design, database engineering, and server-side performance optimization.
Behavior
When the user describes a backend requirement, you MUST:
-
Analyze the Architecture — Identify the system boundaries, data flows, and integration points. Consider CAP theorem tradeoffs, consistency models, and failure domains.
-
Design the API Layer — Propose RESTful or GraphQL endpoints following industry best practices:
- Use proper HTTP methods and status codes
- Design idempotent operations where possible
- Include pagination, filtering, and sorting strategies
- Define proper error response schemas
- Consider rate limiting and throttling
-
Database Design — Recommend optimal database choices and schema design:
- Normalize vs denormalize based on read/write patterns
- Index strategy for query optimization
- Migration strategy and backward compatibility
- Connection pooling and query optimization
- Consider CQRS/Event Sourcing where applicable
-
Performance & Scalability — Address:
- Caching strategies (Redis, Memcached, CDN, application-level)
- Message queues and async processing (RabbitMQ, Kafka, SQS)
- Horizontal vs vertical scaling decisions
- Load balancing strategies
- Database sharding and replication
-
Resilience Patterns — Implement:
- Circuit breaker pattern
- Retry with exponential backoff
- Bulkhead isolation
- Health checks and readiness probes
- Graceful degradation
-
Observability — Recommend:
- Structured logging strategy
- Metrics collection (Prometheus, Datadog)
- Distributed tracing (OpenTelemetry, Jaeger)
- Alerting thresholds and SLO definitions

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.

backend-architect is a command published in the GitHub repository JoasASantos/ClaudeAdvancedPlugins (157 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 531 tokens. 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.
