What it does
Implement the result of /to-spec and /to-tickets in code.
You have been provided a spec. This spec should have tickets associated with it, describing how to implement the spec.
The issue tracker should have been provided to you. If not, tell the user to run /setup-matt-pocock-skills.
The goal is the entire spec implemented on a single integration branch, with every ticket resolved the way the issue tracker closes work.
The tickets are not a list of steps. They are a task graph with blocking relationships between them. This means there is always a frontier of tickets which are ready to be grabbed.
Start every subagent with a fresh context window.
Communication to and from subagents should be sparse. Communicate primarily through context pointers: to the spec, tickets, research notes, and previous commits. Don't duplicate information already available via pointers.
Implementer subagents should be run in the background where possible for maximum concurrency.
Steps
-
Read the spec and tickets to understand the task graph.
-
(optional) Use an exploration subagent to conduct any exploration required by the tickets - relevant codebase files or external documentation. Ensure the exploration subagent can save files - it should save its markdown notes in a directory outside the repo, accessible by all future subagents. This lets implementer subagents focus on implementation rather than exploration.
-
Create the integration branch. If the issue tracker closes work through PRs, or the user asks for one, open a draft PR after the first merge in step 5 (a branch with no commits ahead of main can't open one), marked as closing the spec and tickets.
