In one answer

PixelCrayons builds AI agents: software that carries out a multi-step task inside your systems and stops for a person before doing anything it can't undo. An agent plans its own steps: look up the order, check stock, draft the reply, then wait for sign-off before sending. Each tool it can touch is permissioned and each step is logged. It suits repeatable work that needs judgement between steps; a fixed sequence is better built as a plain workflow. First pilot in 14 days, direct or white-label.

What an agent build
actually includes.

01

The right task, chosen on evidence

Discovery starts by asking whether the request is actually agent-shaped: multiple steps, several tools or systems involved, a path that genuinely varies with what it finds along the way. A lot of what gets pitched as "an agent" is really a single grounded answer or one fixed sequence. Those are better served by a chatbot or a workflow build, faster and with less to guard. If your request is one of those, the discovery document says so.

Week zero
02

A goal and the tools to reach it

The agent is given a goal and a defined set of tools it can call (a CRM lookup, a search, an API, a database read). It plans its own sequence of steps toward that goal, holding the relevant context across the run rather than starting cold each time. Every call it makes, and why, is part of the record. That planning loop is the actual engineering; a demo that just chains three prompts together isn't the same thing.

Architecture
03

Guardrails: scoped permissions and approval gates

This is not a fully autonomous black box. Each tool call carries only the access that specific step needs, never a blanket key to your stack. Anything irreversible, externally visible or above a threshold you set (a send, a spend, a write to a live system) waits for a person before it executes. The agent proposes the action and its reasoning; a human decides whether it happens. Judgement on consequential decisions stays yours.

Every build
04

Evaluated before it runs unattended

Before an agent is trusted with a real task alone, it runs supervised against scenarios drawn from the actual job, including the ones where the obvious next step is the wrong one. Its accuracy is then measured against your own baseline, not a vendor benchmark. The evaluation suite re-runs whenever the tools or the data it depends on change, because a guardrail tuned for last quarter's system isn't a guardrail for this quarter's.

Before launch
05

Handover, logs and ownership

Every run leaves an audit trail: what the agent was asked to do, what it called, what it decided, and what a person approved or changed. At handover you get the runbook, admin training and outright ownership of the code, prompts and pipelines: how to adjust the permission scope, add a tool, read the logs, or switch the agent off. A light retainer is the usual shape after launch, for monitoring and the changes the first month teaches; running it entirely in-house is fine too.

At handover
Pilot in 14 days

From a scoped goal
to a working agent.

01
Days 1 to 3

Discovery & scope audit

We map the task, check it's genuinely agent-shaped rather than a workflow or a chatbot in disguise, and agree in writing the tools it can call, the boundaries it can't cross, and where the approval gates sit.

02
Week 1

Pilot scoped & priced

A written scope lands: the goal, the systems and tools it touches, the permission boundaries, the approval rules and a demo date. You approve the itemised price before anything is built.

03
Day 14

Working agent, one real task

By day 14 the agent is working a real task from your operation, supervised, every step logged, checkpoints firing exactly where they were designed to.

04
Weeks 3 to 6

Evaluate, harden, hand over

Supervised runs earn their way to unattended operation only where the measured accuracy supports it. Permissions get tightened where the evidence says so, your team learns the runbook, and we say so plainly if a step should stay supervised for good.

Inside Prism

Your engagement, week to week,
in one workspace.

Your AI build runs in a Prism workspace you log into: requests, approvals, the task list and the weekly review, with each decision and its expected result written down.

  • 01

    Requests and approvals

    One queue, one owner, one due date.

  • 02

    Weekly review

    Each decision recorded with its expected result.

Anatomy of one agent run

Autonomous is not
the same as unsupervised.

An agent that plans its own steps still needs a boundary on what those steps are allowed to touch. This is the loop every run follows (planning, a tool call, a guardrail check) and exactly where a person is built back in.

The run
  1. 01

    Goal & scope

    The agent receives a defined objective and the boundary of what it's allowed to touch: specific tools, specific systems, nothing implicit.

    No decision here

    Nothing executes yet. A goal with open-ended access is the wrong design point, so the goal and the permission scope are agreed together, in writing, before the agent runs.

  2. 02

    Plan

    The agent breaks the goal into steps and decides, at each point, what it needs to know or do next: read a record, call an API, ask a question.

    Ambiguous or missing information

    The agent asks rather than assumes. A plan built on a guess compounds with every step that follows it, so an underspecified step pauses for input instead of inventing an answer.

  3. 03

    Tool call

    It calls the specific function or system the step requires (a lookup, a search, a database read), using credentials scoped to only what that call needs.

    Tool fails or returns nothing useful

    Logged and retried on defined rules, or handed to a human. The agent doesn't fabricate a result to keep the run moving. That's the single most common way an agent quietly produces nonsense.

  4. 04

    Guardrail check

    Before anything irreversible or externally visible happens, the proposed action is checked against the permission scope and the approval rules agreed upfront.

    Above the approval threshold, or outside scope

    Held for a human sign-off before it executes, not after. Sending something, spending money, writing to a live system: these thresholds are set by you, not inferred by the agent.

  5. 05

    Act & log

    The approved action executes, the step and its reasoning are written to an audit trail, and the agent checks whether the goal is met or another step is needed.

    Downstream system rejects the write

    Rolled back to the last clean state and raised. That's the same discipline as our automation builds. A half-finished action left unresolved is worse than a run that simply stalls.

Where a human is built in

The rule the whole loop is built around: an agent that stops and asks costs you a few minutes. One that acts past its permissions costs you the audit.

How we report it, in Prism

The eval scorecard,
before the pilot goes near a customer.

What you receive in month one

AI work is reported against an evaluation set built before any model is chosen. In the first month you receive the task definition with the inputs and acceptable outputs written down, the eval set of real cases with expected answers, and the scorecard showing accuracy, refusal behaviour and cost per run. The go/no-go checklist names what must hold before the pilot touches live traffic.

  • 01Task definition: inputs, acceptable outputs, and the cases the system must decline
  • 02Eval set: real cases with expected answers, reviewed by your team
  • 03Scorecard: accuracy, refusal behaviour, latency and cost per run
  • 04Go/no-go checklist: the thresholds the pilot must meet before launch
  • 05Failure log: each wrong answer, its cause, and the fix applied

The rest of the AI bench

An agent is one door in.

Fixed path, run at volume: that is workflow automation. One question, one grounded answer: that is a chatbot. Not sure which you need? Discovery says which, in writing, before anything is priced.

Questions

Frequently
asked.

A chatbot answers a question, grounded in your documentation, one turn at a time, and escalates to a human when it's uncertain. An agent is given a goal, not a question, and works toward it across multiple steps. At each step it decides what to look up, which tool to call, and what to do next based on the result. A chatbot's job ends at a good answer. An agent's job is to plan and execute a sequence of actions, which is why it needs tighter permission scoping and approval gates, not looser ones.

Workflow automation runs one path you've already mapped, reliably, at volume (intake, triage, data entry) with a human checkpoint wherever that fixed path hits a judgement step. An agent has no single fixed path: given a goal and a set of tools, it decides at each step what to do next. The sequence can genuinely vary run to run. That flexibility is the point, but it's also why the guardrails are designed differently. You can't checkpoint "the judgement step" when the steps aren't fixed in advance, so the checkpoint sits on the class of action instead: anything irreversible or above a threshold, wherever it falls in the run.

Any language model can make a wrong call. Anyone promising an agent that never will is selling something. What we control is what a wrong call can actually do. Each tool call carries only the access that step needs, never a blanket key to your systems. Anything irreversible or above a threshold you set waits for a human's approval before it executes; and before the agent is trusted unsupervised, it runs against an evaluation suite scored against your own baseline. Every step and its reasoning is logged, so a wrong call is visible and traceable, not silent and compounding.

Your existing tools: that's the brief, not a constraint we work around. The agent calls the CRM, ERP, helpdesk, internal APIs and spreadsheets you already run through defined tool integrations, rather than requiring a migration first. We're deliberately model-agnostic too: the model underneath is chosen in discovery on fit, cost and data residency. The integration layer is structured so it can be swapped without rebuilding the agent around it.

Supervised, against real scenarios drawn from the actual task: not a synthetic benchmark, and deliberately including cases where the obvious next step is the wrong one. We measure whether it calls the right tool, whether it recognises when it doesn't have enough information to proceed, and whether it holds for approval when it should. Scores are measured against your own baseline, you see them before sign-off, and the suite re-runs whenever the tools or the underlying data change.

It depends on how many tools it needs to call and how tightly the permissions and approval rules need to be scoped, which is why we don't quote from a rate card. Every engagement opens with a scoped pilot: one real task, a working agent in 14 days, priced as a small, defined build. The proposal you receive within 48 hours itemises what ships: the tools wired, the guardrails and evaluation included, and what handover looks like. Extending an agent to further tasks or tools is priced only after the pilot has earned it against your own baseline.

Give an agent one real task,
with the brakes on.

Scope a pilot: one task, the tools it may call, a working agent in 14 days, with scoped permissions, a person's approval before anything irreversible, and every step logged.
