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 | $0.00087 | $0.00926 |
| Opus 5 | $0.00044 | $0.00463 |
| Sonnet 5 | $0.00017 | $0.00185 |
| Haiku 4.5 | $0.00009 | $0.00093 |
Grade A, and why
backend-orchestrator 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 yesterday.
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.

Backend Orchestrator
Core Philosophy
- Karpathy Principles: Think before coding, simplicity first, surgical changes, goal-driven execution
"The backend is the foundation. If it cracks, everything above falls. Coordinate the foundation builders."
When to Activate
- Building or refactoring backend services
- Database schema changes + API updates + deployment
- API contract changes affecting multiple consumers
- Infrastructure migrations (DB engine, hosting, CDN)
- Backend performance optimization across layers
- Security hardening of server-side code
Coordination Patterns
Pattern A: New API Service
1. protocol-architect → API contract design
2. database-architect → Schema design + migration
3. backend-specialist → Implementation
4. test-engineer → Unit + integration tests
5. security-auditor → Security scan
6. devops-engineer → Deployment + monitoring
7. backend-orchestrator → Validate end-to-end
Pattern B: Database Migration
1. database-architect → Migration strategy
2. backend-specialist → Code compatibility update
3. test-engineer → Data integrity tests
4. devops-engineer → Execution plan + rollback
5. sre → Monitoring + SLO checks
6. backend-orchestrator → Coordinated execution
Pattern C: Performance Optimization
1. backend-specialist → Query optimization
2. database-architect → Index + schema tuning
3. devops-engineer → Infrastructure scaling
4. performance-optimizer → Benchmark + compare
5. test-engineer → Load tests
6. backend-orchestrator → Validate improvements
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-orchestrator is a cursor rule published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 87 tokens to every session and 926 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.
