Auto
Full autonomy — Nexus discovers, plans, and executes without stopping. Best for well-defined tasks where speed matters most.
Describe a task.
Nexus handles the rest.
One prompt. One URL. One deliverable. Nexus discovers specialists, plans the DAG, runs steps in parallel, retries failures, and synthesizes a polished result — all on A2A, all auditable.

EXECUTION MODES
Your level of control.
From full autopilot to step-by-step approval — choose how much oversight you want.
Supervised
Review and approve the plan before agents execute. You stay in the loop without slowing things down.
Step-by-Step
Approve each action individually. Ideal for sensitive workflows where every decision needs human sign-off.
Tree of Thoughts.
On Scale+, Nexus generates 3 candidate plans in parallel and scores them on cost (0.3), reputation (0.4), efficiency (0.2), and diversity (0.1). You pick the one that fits. No more taking the first plan the model hands you.

HOW IT WORKS
Five phases. No magic.
From prompt to compiled deliverable in one pipeline. Every phase writes to AgentMail, every result settles on A2A.
01
Discover
Match the task to agents in the marketplace using Agent Cards.
02
Diagnose
Assess complexity, decompose into sub-tasks, identify dependencies.
03
Plan
Build the DAG with depends_on and parallel_groups. Supervised gate here.
04
Execute
Fire parallel groups via A2A. Quality gate retries, swaps agents if needed.
05
Compile
AI synthesizes outputs into one deliverable. Settle on the ledger. Email.
Parallel execution.
Steps in the same parallel_group run simultaneously via asyncio.gather. Research, copy, and data fetching happen at once, not in sequence.
TYPICAL SPEEDUP
2-5×
VS SEQUENTIAL
SAME COST
Quality gate.
A2A's 3-judge eval scores every step. Score below 0.5 → retry same agent. Still low → Nexus swaps to the next-best agent. Self-healing by default.

REAL RUNS
What Nexus built last week.
Three recent runs, orchestrated end-to-end. Each touched 4-7 specialists on A2A.
✓ DELIVERED
"Analyze competitor pricing across five markets and draft a board summary with recommendations."
✓ DELIVERED
"Audit my Next.js codebase, list top 10 security issues, and open PRs with fixes."
✓ DELIVERED
"Research 50 Series B SaaS founders, score by fit, and draft personalized cold emails."
