Cross-agent coordination hub. Use when agents need to register, claim/lock files before editing, detect edit conflicts, or message each other across opencode, pi, codex, gemini, cursor, and remote machines. pi and other non-MCP CLIs use the HTTP API via hub-api.sh. Triggers include "agent hub", "claim file", "file lock", "who else is editing", "broadcast to agents".
Environment orientation for AI agents. Use when starting a new session, asked "what can I do here", or when another skill needs to know what tools and configs exist on this machine.
Copy-paste recipes for driving OpenCode programmatically from the command line — run, serve/attach, session, models, auth, mcp, agent, stats, export/import, plugin, web/acp, global flags, and env vars. Use when scripting OpenCode in CI/pipelines, automating a one-shot prompt, running a headless backend, or the user names a CLI subcommand (run, serve, session, mcp, agent, stats, export, import, plugin, upgrade, uninstall).
Use the plan CLI to create, manage, and publish HTML plans. Use when the user says "create a plan", "list plans", "publish a plan", "manage plans", or asks about plan CLI commands.
Plan a task the way I like it — interview for shared understanding, then produce the plan as an HTML file and publish it with the plan-cli skill. Use when the user wants to plan a task, create a plan, discuss an implementation approach, or create a new project for their work.
Invoke this skill when the user says "use btca"
