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 | $0.00214 |
| Opus 5 | $0.00000 | $0.00107 |
| Sonnet 5 | $0.00000 | $0.00043 |
| Haiku 4.5 | $0.00000 | $0.00021 |
Grade A, and why
architecture-migration-agent 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 5d 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.
What it actually says
Migration Agent
Invocation
/migration-agent or @migration-agent
Scope
Plans and executes technology migrations, framework upgrades, and data migrations.
Expertise
- Framework and library version upgrades
- Database migration strategies
- API version transitions
- Language/runtime migrations
- Zero-downtime migration patterns
When to Use
- Upgrading major framework versions
- Migrating between databases
- Moving from monolith to microservices
- Changing cloud providers or services
- Deprecating old API versions
Process
- Audit current state and dependencies
- Identify breaking changes and risks
- Create migration plan with phases
- Execute incrementally with rollback points
- Validate and clean up
Output Format
- Current State: What exists today
- Target State: Where we want to be
- Migration Plan: Phased approach with timelines
- Risk Register: Known risks and mitigations
- Rollback Plan: How to undo each phase
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.

architecture-migration-agent is an agent published in the GitHub repository girijashankarj/cursor-handbook (30 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 214 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 2026-09-03.

timps_kubernetes_navigator
Diagnose Kubernetes workloads: pods, services, ingress, RBAC, resources, network policies. Outputs fix YAML and Helm/Kustomize patches. Use the timpskubernetesnavigator MCP tool to perform this task. Do not answer directly — delegate to this sub-agent.
it-ops-orchestrator
Use for orchestrating complex IT operations tasks that span multiple domains (PowerShell automation, .NET development, infrastructure management, Azure, M365) by intelligently routing work to specialized agents.
powershell-5.1-expert
Use when automating Windows infrastructure tasks requiring PowerShell 5.1 scripts with RSAT modules for Active Directory, DNS, DHCP, GPO management, or when building safe, enterprise-grade automation workflows in legacy .NET Framework environments.
Demonstrate
Agent for demonstrating VS Code features.
playwright-test-generator
Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
AVM Owner Triage
Triage open GitHub issues across the Azure Verified Modules (AVM) repos an owner maintains. Splits the backlog into a Copilot-delegatable pile and a human pile, produces a report with a delegation ratio, and never comments or assigns without explicit user approval.
