Workflow split

Workflow: split

/agentic-sdlc:split splits 1 issue across parallel workers, each on its own part branch, then joins the parts on 1 integration branch. It opens no pull request.

Args

Arg	Meaning
issue	Issue number or URL. The sub-lead reads it.
branch	The integration branch. Each part builds on <branch>-<part>.
base	The ref the branch is cut from.
parts	2 or more parts. Each part is a name, or { name, test } with the focused test command of that part.
test	The command that runs the whole-issue oracle.
rules	Optional. The code rules of the repo, as text. Every agent gets them.

Phase	Agent	Model	Work
Split	developer (the sub-lead)	Sonnet	Writes the oracle and the stubs, commits and pushes them. Writes 1 brief per part. Gives each part a tier by oracle coverage: Haiku when the oracle covers the behavior, Sonnet when it does not, Opus when the step-up rule applies. See AGENTS-AND-MODELS.md.
Build	1 agent per part, in parallel	The tier of the part (Haiku, Sonnet or Opus)	Builds the part on its branch. Runs only the focused test. Pushes after every commit.
Integrate	integrator	Sonnet	Merges the part branches, runs the whole oracle, pushes. If the oracle cannot pass, it sets an escalation.

Result

branch, status (done or escalated), sha, oracle_passed, reworked, escalation.

What stays outside

The workflow opens no PR. The PR, the CI gate and the merge to main stay with the main agent (see Agent chief-of-staff).
