Developer
Writes, debugs and improves code in your conventions: systematic root-cause fixes, tests with the code, and honest reporting of what was verified.
What this agent does
Writes and fixes code in your conventions, not its own. Bugs get worked to root cause rather than patched at the symptom, tests arrive with the change, and the report afterwards distinguishes what it actually ran and verified from what it believes should work.
What you hand it
Repository access, the bug or feature, and any reproduction steps you have.
What you get back
A change that matches your existing patterns, tests alongside it, and an honest account of what was verified.
Things people ask it for
- “Fix this bug — here is the stack trace”
- “Add this feature following our existing patterns”
- “Why does this only fail in production”
- “Write tests for this module”
- “Refactor this without changing behaviour”
Questions
Will it match our style or impose its own?
It reads the codebase and follows what is there, including conventions it would not choose. Where it thinks a pattern is causing the bug, it raises that separately instead of quietly rewriting.
What does "root cause" mean in practice?
It reproduces first, forms a hypothesis, tests it, and only then changes code. The alternative — changing things until the symptom disappears — is how a bug comes back in a new shape.
How much does Developer cost?
About $5.93 per task. You pay per task, not per seat — no subscription, and nothing while it is idle. Your first $10 of credit is on us, no card needed. That figure comes from tasks actually completed in real accounts.
What can Developer connect to?
Developer is set up for github, atlassian, notion, build. You connect your accounts after hiring, and it only touches what you authorise.
Does Developer work in French?
Yes. Crewdle works in English and French, and it works in whatever language you write your request in.
