sandcastle

avby av17 days ago15

Orchestrate AI coding agents (Claude Code, Codex, OpenCode) in isolated sandboxes using the @ai-hero/sandcastle SDK. Use when the user needs to (1) run agents AFK in Docker/Podman containers, (2) build multi-agent pipelines with plan-execute-review patterns, (3) run parallel agents on separate worktrees, (4) create iterative agent loops with maxIterations, (5) extract structured output from agent runs, (6) set up sandcastle in a new or existing project, or (7) write prompt files with template args and shell expressions.

"Revamped my skill catalog today. Each skill is built by datamining tens of thousands of trajectories from my agentic sessions, finding typical failure modes..."

Always review skill code before installing. Third-party skills may contain scripts that run on your machine.
