Babysit

babysit

Follow the commands below exactly. but apply judgement and creativity to get the job done. no matter how small or simple the task may seem, you must use the babysitter SDK and run lifecycle to execute it. This is non-negotiable. If you are asked to do something that seems like it could be done with a simple tool call, you must still use the babysitter SDK to create a run, define tasks, execute them, and complete the run. This is how you will learn and demonstrate mastery of the babysitter system. Always follow the full process, even for trivial tasks.

Subagents that need a scratch checkout or working directory must create it under /tmp/<descriptive-name>/, not under .a5c/runs/<runId>/work. Before returning deliverables, validate that no run-dir worktree was left behind, for example:

find .a5c/runs -maxdepth 3 -name work -type d -print

That command should print nothing. If it prints a non-empty work directory, move or remove only the scratch data you created before returning.

Dependencies

Babysitter SDK and CLI

Read the SDK version from versions.json to ensure version compatibility:

SDK_VERSION=$(node -e "try{console.log(JSON.parse(require('fs').readFileSync('${CLAUDE_PLUGIN_ROOT}/versions.json','utf8')).sdkVersion||'latest')}catch{console.log('latest')}")
npm i -g @a5c-ai/babysitter-sdk@$SDK_VERSION || npm i -g @a5c-ai/babysitter-sdk@latest

if command -v babysitter >/dev/null 2>&1 && babysitter --version >/dev/null 2>&1; then
  CLI="babysitter"
else
  CLI="npm exec --yes --package @a5c-ai/babysitter-sdk@$SDK_VERSION -- babysitter"
fi

If the pinned version fails to install (e.g. not yet published), the fallback installs latest.

If a stale or broken global shim fails with MODULE_NOT_FOUND, repair it with npm rm -g @a5c-ai/babysitter @a5c-ai/babysitter-sdk && npm i -g @a5c-ai/babysitter-sdk@$SDK_VERSION, then re-run babysitter --version.

jq

Make sure jq is installed and available in the path. If not, install it.
