Journey Durable Agent Skill

Use as the durable-objects build stage of the Butterbase journey. Implements the Durable section of 02-plan.md by delegating to durable-objects. Calls manage_durable_objects (deploy). Skipped if the plan has no per-key stateful actors (chat rooms, multiplayer, rate limiters).

Journey: Durable Objects

Stage 3i of the guided journey. Deploy stateful per-key actors.

When to use

Dispatched by journey when current_stage: durable.
Directly via /butterbase-skills:journey-durable.
Skipped (annotated (n/a)) if the plan has no Durable section.

Preflight

If docs/butterbase/03-preflight.md is missing, older than 24 hours, or 00-state.md has app_id: null, invoke butterbase-skills:journey-preflight first. Wait for it to return successfully before proceeding.

Inputs

docs/butterbase/02-plan.md — the Durable section.
docs/butterbase/00-state.md — for app_id.

Procedure

Refresh docs. Call butterbase_docs with topic: "functions". For Durable Object class structure, also WebFetch https://docs.butterbase.ai/durable-objects. Skip if cache is fresh.

For each Durable Object class in the plan:

Print: "About to deploy Durable Object: <name>. Proceed?". Wait for yes.
Invoke butterbase-skills:durable-objects via the Skill tool with the DO spec and app_id. The wrapped skill calls manage_durable_objects action: deploy, sets env via set_env if needed.
Verify with manage_durable_objects action: list and action: get.
Append one line per DO to docs/butterbase/04-build-log.md:

<ISO timestamp> durable manage_durable_objects <do-name> ok

After all DOs are done, tick - [x] durable in 00-state.md, set current_stage: to the next unchecked stage.
Return to journey orchestrator (or ask "Continue to the next stage? (yes/no)").

Outputs

Deployed Durable Object classes.
One line per DO in 04-build-log.md.

Anti-patterns

❌ Sharing state across users via a single DO key — keys should be naturally per-room / per-user / per-resource.

Azure Kubernetes Automatic Readiness

by microsoft

vendor ×3

Assess Kubernetes workloads and cluster configuration for AKS Automatic compatibility. Identifies incompatibilities, generates fixes, and guides migration from AKS Standard to AKS Automatic. WHEN: migrate to AKS Automatic, check AKS Automatic readiness, validate manifests for Automatic, assess cluster for Automatic compatibility, fix deployment for Automatic compatibility, identify AKS Automatic migration blockers, is my cluster ready for AKS Automatic.

Discovers available Azure OpenAI model capacity across regions and projects. Analyzes quota limits, compares availability, and recommends optimal deployment locations based on capacity requirements. USE FOR: find capacity, check quota, where can I deploy, capacity discovery, best region for capacity, multi-project capacity search, quota analysis, model availability, region comparison, check TPM availability. DO NOT USE FOR: actual deployment (hand off to preset or customize after discovery), quota increase requests (direct user to Azure Portal), listing existing deployments.

Interactive guided deployment flow for Azure OpenAI models with full customization control. Step-by-step selection of model version, SKU (GlobalStandard/Standard/ProvisionedManaged), capacity, RAI policy (content filter), and advanced options (dynamic quota, priority processing, spillover). USE FOR: custom deployment, customize model deployment, choose version, select SKU, set capacity, configure content filter, RAI policy, deployment options, detailed deployment, advanced deployment, PTU deployment, provisioned throughput. DO NOT USE FOR: quick deployment to optimal region (use preset).

Unified Azure OpenAI model deployment skill with intelligent intent-based routing. Handles quick preset deployments, fully customized deployments (version/SKU/capacity/RAI policy), and capacity discovery across regions and projects. USE FOR: deploy model, deploy gpt, create deployment, model deployment, deploy openai model, set up model, provision model, find capacity, check model availability, where can I deploy, best region for model, capacity analysis. DO NOT USE FOR: listing existing deployments (use foundry_models_deployments_list MCP tool), deleting deployments, agent creation (use agent/create), project creation (use project/create).

Intelligently deploys Azure OpenAI models to optimal regions by analyzing capacity across all available regions. Automatically checks current region first and shows alternatives if needed. USE FOR: quick deployment, optimal region, best region, automatic region selection, fast setup, multi-region capacity check, high availability deployment, deploy to best location. DO NOT USE FOR: custom SKU selection (use customize), specific version selection (use customize), custom capacity configuration (use customize), PTU deployments (use customize).

This skill should be used when working with LaminDB, an open-source data framework for biology that makes data queryable, traceable, reproducible, and FAIR. Use when managing biological datasets (scRNA-seq, spatial, flow cytometry, etc.), tracking computational workflows, curating and validating data with biological ontologies, building data lakehouses, or ensuring data lineage and reproducibility in biological research. Covers data management, annotation, ontologies (genes, cell types, diseases, tissues), schema validation, integrations with workflow managers (Nextflow, Snakemake) and MLOps platforms (W&B, MLflow), and deployment strategies.

Latch platform for bioinformatics workflows. Build pipelines with Latch SDK, @workflow/@task decorators, deploy serverless workflows, LatchFile/LatchDir, Nextflow/Snakemake integration.

Run Python code in the cloud with serverless containers, GPUs, and autoscaling. Use when deploying ML models, running batch processing jobs, scheduling compute-intensive tasks, or serving APIs that require GPU acceleration or dynamic scaling.
