AI Agent Development

Custom AI agents that do more than chat — they use your tools, follow your rules and complete multi-step tasks end to end, with human checkpoints where the stakes are high.

AI Agent Development — custom AI agents that use your tools and data to complete real tasks end to end

Sound familiar?

  • Support volume grows faster than the team can hire.
  • The team spends hours on repetitive work a model could do in seconds.
  • Customer questions arrive at all hours and wait until morning for a reply.

That is the work this service exists for — scoped up front, delivered in clear milestones, with a fixed estimate before anything starts.

What we build

Agent design & tooling

An agent scoped to a real job and wired to the tools and data it needs to actually complete it.

Tool & system integration

The agent connected to your APIs, CRM and knowledge base so it acts, not just answers.

Guardrails & evaluation

Output validation, scoped permissions and an eval harness so the agent stays reliable once it ships.

Human-in-the-loop controls

Approval steps and audit logs on high-stakes actions, so you keep control of what the agent does.

How we work

1

Use case scoping

We pick a task worth automating and define exactly what "done" and "safe" mean before building.

2

Prototype

We ship a working agent fast so you can judge its decisions on real inputs, not a staged demo.

3

Build & harden

We add tools, guardrails, retries and evaluation so the agent holds up well beyond the happy path.

4

Deploy & monitor

We launch with logging, cost tracking and human checkpoints, then tune the agent from real runs.

What an AI Agent Actually Does

An AI agent is software that uses a language model to plan and complete a task, not just talk about it. Where a chatbot returns text, an agent decides what steps a job needs, calls the tools and APIs required to carry them out, checks its own progress, and finishes — or hands off cleanly when it reaches something a human should decide. The model is the reasoning core; the value is in everything wired around it.

The tasks worth handing to an agent share a shape: they are multi-step, they follow rules that can be written down, they run often enough to matter, and a good outcome is something you can define and check. Support triage, sales follow-up, research and enrichment, document processing and internal operations are the common wins. We begin every engagement by separating those from the tasks that impress in a demo but quietly fail once real, messy inputs arrive.

The point is leverage, not novelty. An agent that clears a routine queue on its own, or drafts and files the predictable ninety percent while routing the awkward ten to a person, gives a team back hours a day. That only holds if the agent is built with guardrails and evaluation rather than blind faith in the model — which is exactly where most do-it-yourself attempts come unstuck.

How We Build Agents That Hold Up

We build on the Claude and OpenAI model families and choose per task — a fast model for classification and routing, a stronger one for reasoning over long context. Around the model we build the parts that make an agent production-grade: a clear tool interface so it can act on your systems, scoped permissions so it can only touch what it should, structured-output validation so downstream code never receives free text where it expects fields, and retries with timeouts so one flaky call does not derail a whole run.

Reliability is engineered, not hoped for. We keep prompts and tool definitions in version control, run an evaluation harness that scores the agent against a labelled set before anything ships, and add guardrails against prompt injection and off-topic drift. High-stakes actions pass through a human approval step, and every decision the agent makes is logged so you can audit exactly what it did and why.

  • Model providers: Claude and OpenAI, with per-step model selection
  • Tool use: typed function-calling against your APIs, CRM and knowledge base
  • Retrieval: vector search over your own data so decisions are grounded
  • Guardrails: scoped permissions, validation, retries and prompt-injection defence
  • Oversight: human approval on high-stakes steps, with full audit logs
  • Evaluation: labelled test sets scored automatically before every release

What's Included, Timeline and Honest Limits

An engagement includes use-case scoping, a working prototype you can judge on real inputs, the hardened production agent with tools, guardrails and monitoring, and a handover of the prompts, tool definitions and evaluation set so your team is never locked into us. A focused single-task agent is typically a four to six week build; agents that orchestrate several systems or demand strict reliability run longer and are staged so you see value from the first before committing to the rest.

We will also tell you when an agent is the wrong answer. If a task is a single step, a deterministic rule or a simple automation will be cheaper and more reliable than a model. If the cost of a wrong action is severe and cannot be reviewed, we keep a human firmly in the loop rather than chase full autonomy. The aim is work genuinely taken off your team, not a fragile showpiece that needs babysitting.
