Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Codecast

Live-stream coding agent sessions to Discord. Zero AI tokens burned.

Setup

First-time setup: see references/setup.md for webhook creation, unbuffer install, bot token, and smoke test.

Invocation

Launch with exec background:true. Background exec sessions survive agent turns and OpenClaw fires notifyOnExit automatically when the process ends. exec background:true command:"{baseDir}/scripts/dev-relay.sh -w ~/projects/myapp -- claude -p --dangerously-skip-permissions --output-format stream-json --verbose 'Your task here'" Note the session ID from the response β€” use it to monitor via process.

Agent Launch Checklist

Start background session β†’ note session ID and PID from response Post to dev channel β†’ announce agent name, workdir, task Write breadcrumb for completion routing: echo '{"channel":"<invoking-channel-id>","relayDir":"<relay-dir>","pid":<PID>}' > /tmp/codecast-pending-<PID>.json Log to daily memory β†’ session ID, relay dir, invoking channel The breadcrumb file tells the heartbeat precheck where to post results when the session completes. It auto-detects completion by checking if the PID is still alive. That's it. When the process ends, OpenClaw's notifyOnExit fires a system event + heartbeat request. The heartbeat handler reads the result from the relay dir's stream.jsonl and posts to the invoking channel.

Completion Detection

OpenClaw handles this natively: tools.exec.notifyOnExit: true (default) β€” system event + heartbeat on process exit Heartbeat precheck script detects completed sessions via /tmp/dev-relay-sessions/ No cron watcher needed Backup: Append this to the inner agent's prompt for an additional signal: When completely finished, run: openclaw system event --text "Done: <brief summary>" --mode now
