Topics covered:

• Why data pipelines are more than copying from point A to point B (schema normalization, incremental loads, schema evolution as a SEV)
• Scaffolding a project with uvx dlthub start and what gets generated for Claude (skills, roles, starter pipeline)
• Installing dlt toolkits for REST APIs, data quality, and file systems
• One-shotting a GitHub issues pipeline with Claude and the REST API skill
• Switching destinations with a single line of code (DuckDB, Snowflake, Iceberg, S3, Hugging Face)
• Schema contracts with Pydantic and the gatekeeper pattern for handling bad rows
• Attaching to a pipeline with Marimo notebooks to inspect data, schemas, and run data quality checks
• Failure introspection via checks.get_failures() and feeding failed rows into another dlt pipeline
• Exporting dlt transformations as dbt models for regulated industries (health, finance)
• Where Ibis fits in (Python expressions that compile to SQL in Snowflake)
• Snowflake Cortex AI operators through Ibis as a way to shift left on AI workloads
• Skills vs. MCP in the dlt setup, and how skills get tuned differently for Claude, Codex, and Copilot
• dltHub Pro for hosted pipelines, monitoring, and deploying Marimo notebooks as dashboards

If you have ever wired up a brittle ingestion script, fought with a managed connector that did not quite fit, or wondered how agents should actually pull data into your warehouse, this episode is for you.

Holden Karau (Snowflake, formerly Databricks) and Lisa Cao (Databricks DevRel) joined us to dig into what it actually looks like to write Spark code with AI agents in 2026.

We worked through a real example from Holden's High Performance Spark Second Edition — a Goldilocks-style exact percentiles problem across hundreds of columns — and watched Claude Code handle it from a cold-start repo, then again with proper context and a reference solution.

Lisa walked through using a skill file to get Claude to write declarative pipelines the right way instead of hallucinating the syntax, and we talked about why local mode, Arrow UDFs, and the upcoming Python UDF transpilation work in Spark 4.3 matter for AI-assisted Spark development.

We also covered: why the "agents trying to shut you up" failure mode shows up in code generation, the case for property-based testing as a guardrail for agentic coding, Spark 3 to Spark 4 porting as a more reliable path than one-shotting Spark 4, and where agents still struggle (dependency management, Spark internals, real stack trace debugging vs. pattern matching from Stack Overflow).

Shabnam Emdadi, staff software engineer at Shopify and Temporal Constellation member, on what AI frameworks are rediscovering from distributed systems, why retries are more expensive in an LLM world, and the case for judgment over one-more-prompt addiction.

Francesc Campoy, Go expert and JustForFunc creator, on his first take on Temporal after the Go workshop, the cognitive offloading vs cognitive surrender distinction, and why software engineering still matters in production.

Vibe Check co-hosts Melissa and Shy on the Replay keynote: Melissa's robot arm demo and agents workshop, and Shy's marathon to ship 2,300 hackable conference badges, including how Codex and Claude got the firmware over the line.

Brian Douglas from Paper Compute breaks down their work on agent runtime and durable session recording, and where context engineering is heading post-MCP.

Beverly Lu from Chime walks through what it actually takes to ship AI in a regulated fintech: evals as a discipline, domain experts in the loop, and per-model harnesses.

We close with Johann Schleier-Smith from Temporal on the AI announcements from the keynote: priority and fairness, large payload storage, workflow streams, serverless workers, and where the harness conversation is heading.

Sarah Deaton, Technical Content Engineer at Anthropic and the person who owns the Claude Code docs, joined myself and my co-host Angela Zhou (Sr Technical Curriculum Dev @ Temporal) to walk through what's new and what's underused in Claude Code. We covered Claude Design for non-designers, the difference between CLAUDE.md, skills, hooks, and subagents (and when to reach for each), routines that run on schedules or GitHub events, the new rewind feature, auto mode, forked subagents, and the layers of sandboxing available for safer execution.

Topics covered:

• Claude Design for visual work, mockups, and slide decks (and the handoff into Claude Code)
• When to use CLAUDE.md vs skills vs hooks vs subagents
• Why hooks are the deterministic layer underneath the model and where teams misuse CLAUDE.md
• Slash init for scaffolding a new repo with Claude Code
• Routines: scheduled tasks plus GitHub events and API triggers
• Rewind: pulling failed attempts out of the context window without polluting the next try
• Auto mode and the classifier that gates risky actions
• Forked subagents: subagents that inherit the full conversation but keep their work isolated
• Sandboxing tiers: slash sandbox, dev containers, VMs, and Claude Code on the web

Terry Ryan from Google walks us through Naval Plan, a real app he built (and actually uses) to plan sailing trips using ADK Go. The app combines agentic research — pulling from old sailing forums and local knowledge — with deterministic API calls for tides, weather, and sunrise/sunset data. We dig into how the agents are architected, the quirks of working with Google Search as a tool in ADK, and Terry's dev workflow using Gemini CLI.

Topics covered:

• Building Naval Plan: an agentic sailing trip planner with ADK Go
• Mixing agentic research with deterministic API tools (tides, weather, sunrise/sunset)
• ADK agent architecture: subagents, tool composition, and the Google Search tool workaround
• Structured JSON output from agents and how to make it reliable
• Dev workflow: Gemini CLI in YOLO mode, git-based rollback, and prompt management
• Using LiteLLM for multi-model support in ADK
• Tool count limits and context window considerations
• Upcoming Temporal + ADK integration

In this livestream, Donald (AI Foundations engineer at Temporal) and Mark Biza (DX engineer at Vercel) join us for a Vibe Check on skills — what they are, how to build them, and what they unlock for AI-assisted development. Donald previews the upcoming Temporal Agent Skill and live-demos it in Claude Code, while Mark walks through skills.sh, the distribution platform Vercel built to share skills across agents and teams.

We go beyond the surface and explore:

• What Claude Code skills actually are — markdown files with YAML frontmatter that give coding agents structured, domain-specific context
• Why skills matter: how they guide agents past incomplete or inaccurate training data toward real best practices
• How the Temporal Agent Skill is structured — a shared core for cross-language concepts plus language-specific folders for Python, TypeScript, Go, and more
• A live demo: Claude Code building a durable payment workflow using the Saga pattern — unprompted — because it was encoded in the skill
• Why being able to run and iterate on workflow code (not just write it) is the key unlock for agents debugging Temporal apps
• How skills.sh works — installation via npx skills add owner/repo, the leaderboard, auditing, and community contributions
• Vercel's Chat SDK skill and how it scaffolds agents for Slack, Discord, Teams, and WhatsApp
• Using skills outside of code — marketing, SEO, copywriting, and motion graphics with Remotion
• Skills vs. MCP: why the future likely uses both together, and where each fits
• The case for skill cross-dependencies and skill bundles — a feature Donald and Mark noodle on live

If you're building on Temporal, experimenting with Claude Code, or trying to understand how to give your coding agents better guardrails and domain knowledge, this episode is for you.

The Temporal Agent Skill is launching next week — look for it on skills.sh.
