Change or extend a Tessl factory that is already set up on this repository, and suggest what to add next. Use when someone wants to let a teammate start runs, change the model an automation uses, change what an automation does, change how Code Review behaves, stop or remove an automation, update the setup hook, change what the cloud environment can access, add another automation, set up Learn from past work so the factory learns from its mistakes, act on its findings, or asks what they should add to their factory.

Run a branch's setup hook on a Tessl cloud machine and report its output and what the machine then has, so factory setup can confirm the hook works in the cloud before it goes live. Use when factory setup launches a cloud run to check a setup hook.

Write and file a GitHub issue for the Tessl factory to turn into a pull request, with the person's own GitHub account. Use when someone wants Tessl to work on something in a repository whose factory takes GitHub issues, wants a task split into issues the factory builds in order, or asks how to write an issue for Tessl.

Creates CI/CD pipelines, test workflows, deployment configurations, matrix builds, caching strategies, composite actions, Docker actions, JavaScript actions, and reusable workflows. Use when creating or scaffolding GHA resources, writing .github/workflows YAML files, setting up build automation, implementing deployment pipelines, adding security scanning, or building reusable actions — including triggers like 'create a workflow', 'build a pipeline', 'add CI', 'set up GHA', or 'generate a YAML workflow'.

Comprehensive toolkit for validating, linting, and testing GitHub Actions workflow files, custom local actions, and public actions. Use this skill when working with GitHub Actions YAML files (.github/workflows/*.yml), validating workflow syntax, testing workflow execution with act, or debugging workflow issues.

Generate Terraform modules, configure providers, define variables and outputs, set up remote state backends, and write production-ready HCL (.tf files) following current standards. Use when creating new Terraform resources, building Terraform projects, writing infrastructure as code (IaC), scaffolding AWS/Azure/GCP cloud infrastructure, working with terraform plan/apply workflows, or structuring multi-environment configurations.

Comprehensive toolkit for validating, linting, testing, and automating Terraform configurations and HCL files. Use this skill when working with Terraform files (.tf, .tfvars), validating infrastructure-as-code, debugging Terraform configurations, performing dry-run testing with terraform plan, or working with custom providers and modules.

Back up new Audible audiobook purchases, decrypt to M4B, and append to books-library.csv. Use on "audible backup", "check new audiobooks", "sync audible library", or from weekly scheduled task.

Checks tracked upcoming TV shows in watchlist.json and sends a Telegram notification message via MCP when any have been released. Use when running nightly release checks, monitoring streaming release dates, or checking whether new episodes or shows from a watchlist are now available to watch. Fires nightly via its own scheduled_tasks row (post-#404).
