Confident output, wrong behavior
The code compiles. The naming fits. The behaviour is still wrong because the agent never knew the product rule.
Tasks
Watch the work happen
Each task is a discrete unit of work codemix executes on its own. You can see exactly which step it's on, what's already done, and where it's blocked — without having to ask. The plan stays visible and you can intervene at any point.
The agent problem
Your agents are building confidently. The problem is they're guessing.
AI coding tools are good at plausible output. They are bad at knowing what the product is supposed to do. That is not a prompting problem. It is a missing context problem.
Without product intent, agents fill gaps from nearby code. The diff looks clean. The tests pass. The behaviour is wrong in a way you find after merge.
Drift that surfaces too late
By review time the mistake has usually spread. Fixing it costs more than building it properly did.
Product knowledge in the wrong places
The domain model lives in heads, tickets and old threads. Every new task starts with another context download.
Velocity that creates invisible debt
Ungrounded generation does not just make output faster. It makes wrong assumptions pile up faster too.
Start from product intent
Know what the system is supposed to do before you touch the code
Most drift starts before the first line is written. A ticket title is not enough context for a human or an agent.
Codemix keeps the product model queryable: concepts, flows, constraints and decisions. You start from intent instead of reverse-engineering it from nearby code.
Project overview
See everything in flight, at a glance
The overview surfaces every active proposal, running task, and recent conversation in one place — no status updates required. Codemix keeps it current as work progresses, so anyone on the team can see what's happening and where things stand.
Hand agents better briefs
Give agents the why, not just the what
An agent handed a ticket title will invent the missing context. A grounded brief gives it a fighting chance.
Codemix turns product intent into implementation tasks with the behaviour, edges and dependencies attached. Less prompting. Fewer plausible wrong answers.
Task plan
A complete task plan, ready to execute
Once a proposal is approved, codemix breaks it into parallelisable tasks and executes them autonomously. The task plan keeps every behavioural commitment visible while the build is underway.
Ask the product mid-build
Stop guessing what the rules are in the middle of a task
Edge cases show up during implementation. That is normal. Hunting through old threads is not.
Codemix lets you ask the product model mid-build and get the rule that applies. Better while the fix is one file than after it becomes a revert.
Conversations
Work through the problem together
Codemix grounds every reply in how your product actually works — not generic advice, but specific to your codebase and domain. When you're ready, it drafts a proposal that captures the intent in a form the rest of the team can review and challenge.
Review for intent, not just syntax
Catch the cases where the code is right and the behavior is wrong
Code review catches style and structure. It is weaker at catching a clean implementation of the wrong idea.
Codemix compares the change to the intent before merge. That catches the kind of mistake tests often miss: code that works, but does the wrong thing.
Proposal review
Catch the problems before the work starts
Codemix flags gaps in the proposal — ambiguities, missing cases, or things that conflict with how the product already works. Resolve them here, and the work that follows is far less likely to need rethinking.
How it works
How Codemix carries context through the full lifecycle
Most product drift happens in the handoffs: from discussion to spec, spec to task, task to code, and code back to the roadmap. Codemix keeps those handoffs explicit.
- 00start
Start with a conversation or from code
Chat with codemix if you're still at the idea stage, or import your existing codebase.
A product baseline
Start with an interview
Talk through the product in plain English. Codemix turns the important parts into something the team can inspect, question, and build from.
Start with the repo
Connect the existing codebase. Codemix reads how the system behaves today, including the bits nobody remembered to write down.
- 01model
model the product
Codemix builds a working model of the product: the concepts, screens, actions, rules, edge cases, and decisions that explain how it is meant to behave.
A model the team can ask about
- 02proposal
shape the change
Before implementation starts, you can ask questions, edit the spec, and turn a rough idea into a concrete proposal for what should change.
A proposal people can review
- 03tasks
write the tasks
Once the proposal is approved, Codemix turns it into implementation work. Send it to Linear or Jira, hand it to a coding agent, or let humans and agents split it up.
Tasks with the context attached
- 04answers
answer questions mid-build
Implementation always uncovers questions. Codemix gives engineers and coding agents answers from the product model, so they don't have to guess from a ticket title or a nearby file.
Product answers during the build
- 05review
review what changed
Codemix reviews the code against the product decision, not just against style, tests, or neighbouring code. That's where a lot of agent mistakes hide.
Review that checks intent
- 06release
ship, then update the spec
Shipping often reveals details nobody saw at planning time. Codemix helps fold those decisions back into the spec, so the source of truth doesn't go stale the moment the PR lands.
Code and spec brought back together
- 07feedback
bring the context forward
Bring in bugs, customer feedback, support notes, and product signals. The next proposal starts with the context you already built, instead of another round of archaeology.

Stop reviewing code that only looks right.
Codemix gives engineers and tech leads a shared product model that agents can build against. What ships should match what was decided, not what the agent guessed.
