Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like). 2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data. 4.

Related use cases
See what Claude Code forgot each time it compacted a session
After checking 73 compactions and finding 26 summaries that dropped a server, deployment or port the agent was using, a developer built compact-receipts to log what each compaction dropped.
Generate a visual workspace UI for each agentic coding task
Built Radix so you prompt an agent to generate a persistent on-disk interactive widget workspace for the task at hand.
Auto-route model and effort for each Claude Code task
Built a JEV Auto Router skill that picks the model and reasoning level for each Claude Code task via TypeSafe Jev, with more agents planned.
Generate slide decks from a repo that flag when they drift from the code
SlideOps is an agent skill that turns a codebase into a slide deck where every file reference carries a line range and hash, so a fast offline check tells the agent exactly which slides went stale.
