AI Agent Development

AI agents that ship — and stay shipped.

Agent demos are easy. Agent reliability is hard. We build evaluated, observable agents that complete real tasks in production — with the guardrails, evals, and human-in-the-loop fallbacks that demos skip.

Most agents work in a demo. Few work in production.

Someone builds an agent that handles a happy-path task in a notebook, the team gets excited, and six months later it's still in pilot — because as soon as it meets real data, the success rate craters from 95% to 40%.

The reasons are predictable, and they're not about the model. They're about everything around the model: tool reliability, memory boundaries, error handling, eval coverage, observability, and designing for failure modes instead of demos.

Six classes of agents we ship into production.

Single-purpose task agents

One agent, one tool surface, one job — research, summarization, classification, extraction.

Multi-agent systems

Coordinator + specialists. An orchestrator delegates to focused worker agents.

Browser-using agents

Navigate, click, fill forms, extract from web UIs. Playwright, Browserbase, computer-use.

Voice agents

Inbound/outbound phone agents on LiveKit, Vapi, Retell. Support, qualification, scheduling.

Customer-support copilots

Tier-1 agents with KB retrieval, ticket triage, escalation, tone control.

Internal ops agents

Database queries, ETL, finance reconciliation, RevOps. Boring, valuable, high-ROI.

Evals before agents.

Most teams build the agent first and figure out evals later. We do it backwards.

01

Define success, in writing

Concrete, measurable rubrics for what 'the agent did the task correctly' means.

02

Build the golden dataset

50–500 real examples with correct answers. The harness everything runs against.

03

Build against the harness

Every prompt iteration, model swap, and tool change runs the full eval. Regressions block merge.

04

Shadow production traffic

Run in shadow mode against real traffic before serving users. Diff against humans, then promote.

What “production-ready” actually requires.

  • Tool input/output schemas with runtime validationPydantic / Zod on every tool boundary, with structured errors the agent can recover from.
  • Retry, fallback, and circuit breakersEvery external call has a retry policy and a fallback. Repeated failures circuit-break and escalate.
  • Human-in-the-loop checkpointsHigh-stakes actions pause and ask a human. Configurable per workflow.
  • Cost and latency budgetsHard cost ceilings and latency targets. Runaway agents are killed and logged.
  • Observability with trace IDsEvery LLM call, tool call, and decision tagged. Production failures are replayable.
  • Eval regression gates on deployCI runs the golden-dataset eval on every commit. Regressions block deploy.

Common questions.

What success rate should I expect?
Depends on the task. Narrow tasks (classification, extraction, routing): 85–95%. Complex multi-step tasks: 70–85% with human-in-the-loop on the long tail. Anyone promising 99% on a complex task is showing you the demo set.
How do you measure agent quality?
Measurable rubrics, a golden dataset of 50–500 real examples, scoring via LLM-as-judge plus structured assertions, tracked over time, with regression gates in CI.
Single agent or multi-agent?
Single-agent first, always. Multi-agent earns its complexity only when role separation genuinely helps quality.
What models do you use?
Mixed — frontier models for reasoning, smaller open models for classification and routine tool calls. Often multiple models in one agent.
Self-hosted or hosted models?
Both. Hosted APIs win on capability and speed; self-hosted wins on privacy, cost at scale, and latency. See our Private LLM page.
What happens when a model gets deprecated?
The retainer covers model migrations. We re-run the eval harness against the candidate, port if it's better, roll back if it isn't.
