Switch coding agents without starting over.
Nexus Prime carries the decisions, constraints, and next step from one coding agent to another—so the work keeps moving.

How Nexus fits in
One local layer for agent work.
Install it once. Use the CLI to prepare a durable handoff, then connect your coding agents through MCP.
Works with the coding tools your team already chose.
-
01npm package
Install on your machine.
npm install -g nexus-prime -
02CLI
Prepare the handoff.
Keep the objective, settled decisions, relevant scope, and next check together.
-
03MCP
Continue in the next agent.
The receiving tool starts from the same working brief.

Built around your workflow
Choose the handoff your team already has.
Pick the environment closest to yours. See what Nexus Prime carries and exactly where the next agent begins.
Move from diagnosis to a tested checkout fix.
One agent isolates the failure. The next opens the affected boundary with the decisions and regression target already attached.
- Nexus carries
- Reproduction · ruled-out causes · affected boundary
- Next agent begins
- Patch the guard and run checkout regression
Keep the risk boundary attached to the change.
Move from clarified acceptance criteria into implementation and review without asking each session to reinterpret the requirement.
- Nexus carries
- Acceptance criteria · risk boundary · test evidence
- Next agent begins
- Review the affected path and complete release checks
Continue a migration without reopening settled choices.
Each batch starts with the compatibility decisions, completed modules, and blockers from the work that came before it.
- Nexus carries
- Compatibility decisions · completed modules · blockers
- Next agent begins
- Implement the next batch and run the mapped regression
Turn a failure cluster into a bounded change.
The implementation session receives the recurring failure, the chosen constraint, and the exact workflow that needs another eval run.
- Nexus carries
- Failure cluster · chosen constraint · affected workflow
- Next agent begins
- Change the orchestration path and rerun the frozen eval
Start the next session inside the right part of the codebase.
Repository conventions, relevant modules, and working commands arrive before the first edit—not after another broad scan.
- Nexus carries
- Conventions · relevant modules · working commands
- Next agent begins
- Open the target module and make the first scoped change
Keep the customer outcome attached to implementation.
The build session starts with the requirement, settled trade-off, and one open decision that still needs an owner.
- Nexus carries
- Requirement · settled trade-off · open decision
- Next agent begins
- Implement from the brief and surface the remaining decision
Compact working context
The next agent gets the decisions, not the transcript.
Nexus Prime narrows the working set to the objective, settled decisions, relevant scope, and next check before the work moves.

Developer community
Builders want agent work that holds together.
01 Bounded execution
“The bounded execution piece is the most valuable part of this architecture — unbounded agents accumulate stale context that silently distorts later decisions…”
02 Workflow continuity
“The ‘works in one prompt, falls apart over a workflow’ problem feels mostly like state + execution, not raw model IQ.”
03 Durable state
“Yeah, the fix is durable state + an audit trail, not bigger prompts: keep a run log (decisions, patches, tool calls) and rebuild context from artifacts every step.”
For engineering teams
Start with one workflow your team repeats.
Turn one recurring handoff into a reusable team workflow. Each agent receives the decisions, relevant scope, and next check it needs to continue.
Start a team pilotQuestions
What changes after install?
Does Nexus Prime replace my coding agent?
No. It keeps work usable as it moves between the coding tools you already use.
What moves with a handoff?
The receiving agent gets the objective, settled decisions, relevant scope, and next check.
Which coding agents can I connect?
Connect Claude Code, Codex, Cursor, Windsurf, and OpenCode through the Nexus setup flow. See integrations.
Can I start as one developer?
Yes. Install the npm package, create an account, and connect the tools you already use.
How does a team pilot start?
Tell us the workflow, tools, team range, and outcome you want. We’ll outline a pilot around that handoff.
