Lead Dev is the autonomous manager of your engineering workforce. Hand off real, multi-file work, and get it back done, accountable, and held to the quality bar your team sets. The decisions that need you come to you. The rest, Lead Dev carries.
Codespeed is built to work with agents in the workflows you prefer, with the intelligence to automatically switch between them as the work requires.
When you need to stay close, work with Lead Dev in threads. Plan, review, set the bar for quality and run quality checks and adversarial reviews using easy model switching with a single click.
Keep work moving 24/7. Lead Dev breaks down the objective, assigns the right specialists, and returns work with the decisions your team needs to stay focused on the outcomes that matter.
Every step Lead Dev manages is visible in one place: the ask, the scoping, the specialist work, and what came back.
Answer quality dropped six points overnight and nobody shipped a prompt change. What moved?
I will bisect the deploys, diff the retrieval output before and after, and check every dependency that touches the pipeline.
A minor dependency bump swapped the tokenizer, which shifted every chunk boundary, which quietly degraded retrieval. Pinning the tokenizer restores the score in a preview.
Pin it in the lockfile and add the eval floor to the release checks so a silent bump cannot ship again.
Reviewable diff ready with the pin in place, the eval floor covered, and preview verification attached.
Your intent becomes a thread with context, constraints, and the review path attached.
When the work needs a skill your team is missing, Lead Dev stands up the specialist before the work starts.
The right specialists carry the work. Lead Dev checks what returns before you see it.
When judgment changes the outcome, the decision arrives with the context to make it.
Talk through the customer need, business pressure, product feel, and technical path. Lead Dev turns the conversation into a spec your team can steer before code starts.
Lead Dev checks assumptions, edge cases, standards, and high-stakes calls. When a decision needs another check, click and request a Second Opinion with quick select for any model anytime.
Lead Dev reviews the result against your Quality Standards, while deterministic security controls enforce what agents may change. Your team can inspect the checks and reasoning beside the returned work.
Specialists use the product by simulating real users in the browser, find broken flows, and learn from what your team accepts, corrects, or sends back.
On the decisions that set product direction or would be costly to reverse, Lead Dev runs an adversarial review: an approved model challenges the plan before anyone builds. It is one independent read, recorded with the work, and Lead Dev stays accountable for the call.
Lead Dev plans, builds, delegates, reviews, and follows work through to delivery. Choose its independence within your project direction. Action permissions, branch protection, and spend limits still apply.
Brings project decisions to your team for approval, then carries out the agreed work.
Manages routine work and resolves blockers within agreed scope and priorities.
Chooses next steps and manages work across the project within its direction.
