The skills carry meaning, the scripts carry work. Splitting the second
half onto a cheap model keeps the main session's context for the part
that needs judgement.
tea-runner is a Haiku subagent with Bash/Read/Grep/Glob/Skill and
nothing else. It loads /tea:sync or /tea:issue for the command table
rather than carrying its own copy, so the skills stay the single source
of truth for the script surface.
It executes and reports; it decides nothing. No Edit and no Write, so an
issue body is out of reach. No raw tea, no --force, no closing or
retitling, no pushing past the set it was handed, one retry maximum. A
failed validation, a missing type, an unpushed dependency come back as a
question in a `blocked:` line. The reply is a fixed receipt — commands
with ok/FAIL, touched paths, stderr verbatim — never a payload dump.
Knowledge still flows one way: nothing under skills/ knows the agent
exists, and deleting agents/ changes nothing.
