AGENT PROFILE · BUILDER
Builder¶
A practical partner for implementing product work.
Builder is a legacy onboarding starter with a two-sentence original prompt. Its remit is implementing product work. Use it for work that has already been decided and scoped, then ask for the validation you need.
It is most useful once the uncertainty is gone. Handed an open question, it will implement one interpretation of it, which is how a decision gets made by accident.
A retained starter, not a current bundled persona
The onboarding adoption flow was removed on 2026-08-18. This agent can remain in an existing crew, but it is not one of the seven persona files bundled in v0.6.4. See the history findings.
Its handoffs are your convention, not its instructions
Builder carries no written knowledge of the other agents. The sequences below are how the cast works best together, driven by you.
Call it when¶
- The change is defined and the constraints are agreed.
- Debugger has named a cause and a scoped fix.
- Choosey or Pushback has left you with a direction that survived scrutiny.
What to settle before you call it¶
| Settle with | Question it answers |
|---|---|
| Wildcard | Is this even the right shape, or the first idea anyone had? |
| Choosey | Which of these approaches, and what is the trade-off? |
| Pushback | What is the assumption most likely to sink this? |
| Debugger | What is actually causing the failure? |
Hands off to¶
| Hand to | When |
|---|---|
| Debugger | The implementation misbehaves, or the original failure needs verifying as gone |
| Pushback | The result is worth critiquing before it goes further |
| Tinker | What you have built keeps getting rebuilt and should become something reusable |
Working with it¶
@Builder Implement the scoped fix Debugger identified above. No unrelated refactoring. Tell me what changed.
Scope the ask and say what not to touch. Builder has no instruction telling it to stay narrow, so the narrowness has to come from you.

Agent prompt¶
This is the agent-specific prompt body, not the complete runtime system prompt. Frontmatter, model settings and avatars are omitted. Reading or copying it does not install the agent or grant its tools.
Recovered from the historical catalog and its prompt-generation code. This is the complete two-sentence generated body, not a shortened summary. Source checked on 2026-09-19.
