Enterprise practice

AI & Agentic Systems

AI experiments are not becoming dependable production systems. Models may perform in isolation while the surrounding workflow lacks reliable context, permissions, evaluation, and human control.

Talk to an Engineer Explore the engineering scope

When organizations bring us in

The commercial trigger

A model, copilot, or agent must operate inside a material business or regulated workflow, and its decisions must be observable, bounded, and recoverable.

Who owns the problem

Accountable technology leadership

Technology, product, and data leaders moving AI from demonstration into accountable production use.

What we engineer

Production AI applications and agentic workflows connected to real enterprise systems.

Agent and tool orchestration

Retrieval and enterprise knowledge pipelines

Model routing and structured outputs

Human review, escalation, and override paths

Evaluation, tracing, and production observability

Identity, permissions, and workflow integration

What makes it difficult

Consequence changes the technical work.

The hard part is rarely the model call. Reliability depends on changing data, nondeterministic behavior, tool failures, authorization boundaries, latency, cost, and knowing when the system should stop and ask a person.

How we approach it

Architecture through controlled release.

Define decision boundaries and failure modes before selecting models
Build evaluations around representative tasks, edge cases, and unsafe behavior
Integrate tools through explicit contracts and least-privilege access
Release with observable controls, human escalation, and rollback paths

Production AI X-Ray

The model is not the production system.

Reveal the engineering layers that turn model capability into bounded, observable workflow behavior.

Routing

Select an evaluated model and an explicit fallback path.

Retrieval

Ground work in approved, versioned sources.

Permissions

Authorize data and tools for the purpose of the request.

Evaluations

Gate behavior against quality, policy, and safety cases.

Fallback

Degrade safely when a model or dependency fails.

Human escalation

Stop and route material exceptions to an accountable person.

Observability

Trace latency, cost, errors, and task outcomes.

Audit

Retain reviewable decisions, versions, and approvals.

Rollback

Restore a known release when evidence crosses a threshold.

Buyer context

What has to be true before this investment works.

Buyers arrive after a useful model demonstration stalls at the boundary between language and accountable action. The production question is not whether a model can answer. It is whether the complete workflow can use tools and enterprise data without exceeding authority, hiding failure, or leaving operators unable to intervene.

Problems behind the search

Visible symptoms, technical causes, and the decision to make.

The agent works only on the happy path

What the buyer sees: Tool calls loop, missing context produces confident answers, and unusual cases fall into an unowned queue.
What causes it: The prototype encoded a conversation, not a stateful workflow with typed tools, terminal states, and exception ownership.
What to evaluate: Evaluate the workflow state model, tool contracts, stop conditions, and the exact point where a person assumes control.

Permissions exist outside the execution path

What the buyer sees: A user can ask the agent to retrieve or change data that the underlying application would normally restrict.
What causes it: Prompts are being used as access control, or service credentials collapse the user and agent identities into one broad role.
What to evaluate: Require authorization at retrieval and action time, scoped credentials, purpose-aware policy, and denial tests.

Nobody can prove that an update is safer

What the buyer sees: Model, prompt, retrieval, or tool changes ship after anecdotal review and production regressions appear later.
What causes it: There is no representative evaluation set, version lineage, or release threshold tied to task and safety outcomes.
What to evaluate: Inspect evaluation coverage, versioning, shadow tests, rollback triggers, and ownership for failed evaluations.

Architecture depth

The design decisions underneath the outcome.

Agent or deterministic workflow

Use deterministic orchestration when states and rules are knowable. Introduce an agent where the work requires interpretation, planning, or variable tool selection, while keeping irreversible actions behind explicit policy and approval.

Context, memory, and grounding

Separate short-lived task state from durable memory. Retrieval should preserve source identity, freshness, entitlements, and citations; memory writes need purpose, retention, and deletion rules.

Tools, MCP, and authorization

MCP can standardize how tools expose capabilities, but it does not create a security boundary by itself. Each tool still needs typed inputs, least privilege, policy checks, idempotency, timeouts, and reviewable results.

Routing, fallback, and observability

Route models by task risk, capability, latency, residency, and cost. Trace model input lineage, retrieval, tool decisions, approvals, outcome, and fallback without copying unnecessary sensitive content into telemetry.

Material use cases

Where the system fits, and where people remain accountable.

Clinical document intake

Classify incoming material, extract bounded fields, identify missing evidence, and route the packet into the existing clinical or administrative queue.

Human accountability. A clinician or authorized operator owns clinical interpretation and exceptions.

Engineering constraints. PHI access, source provenance, document quality, hallucinated fields, and integration with the system of record.

Regulatory evidence collection

Locate control evidence across approved systems, assemble a review packet, and flag stale or conflicting artifacts.

Human accountability. Control owners attest sufficiency and auditors determine acceptance.

Engineering constraints. Evidence freshness, authorization boundaries, immutable provenance, and avoiding unsupported compliance conclusions.

Security investigation assistance

Correlate alerts and approved telemetry, propose investigation steps, and execute low-risk queries through bounded tools.

Human accountability. Responders own containment and consequential actions.

Engineering constraints. Hostile log content, tool misuse, incomplete telemetry, urgency, and preservation of investigative evidence.

Implementation sequence

From system truth to an operated release.

01
Model workflow state
Trace decisions, terminal states, reversible actions, exceptions, and the moments that require accountable human judgment.
02
Design tool contracts
Give every tool typed inputs, bounded authority, idempotency rules, timeouts, and an explicit denial response.
03
Propagate identity and retrieval authority
Carry user identity and purpose through retrieval and action instead of inheriting a broad service-account view.
04
Build the evaluation corpus
Represent routine work, edge cases, hostile content, denied requests, and known failure histories with release thresholds.
05
Test denial and escalation paths
Prove that prohibited actions stop, ambiguous work reaches the right reviewer, and interrupted work can resume safely.
06
Shadow, stage, and roll out
Compare agent decisions with the current workflow before progressively enabling bounded actions and rehearsed rollback.

Failure modes

How production breaks, and what the architecture must do next.

Prompt injection through retrieved content

Signal. Instructions embedded in documents alter tool selection or disclosure behavior.

Architecture response. Treat retrieved text as untrusted data, isolate instructions, enforce tool policy outside the model, and test adversarial corpora.

Runaway action or cost

Signal. Repeated planning, retries, or tool calls consume budget without advancing the task.

Architecture response. Apply step, time, token, and spend budgets with circuit breakers and an explicit incomplete outcome.

Authorization mismatch

Signal. The agent can see or act beyond the requesting user or stated purpose.

Architecture response. Propagate identity and purpose to every retrieval and tool call, deny by default, and record policy decisions.

Dependency or model failure

Signal. Latency, refusals, schema drift, or provider outage makes the workflow unreliable.

Architecture response. Use typed validation, bounded retry, model or deterministic fallback, durable state, and safe human takeover.

Buyer evaluation

Questions to resolve before selecting an approach.

Can the workflow be deterministic instead of agentic?
Which actions are reversible, approval-gated, or prohibited?
How are user identity and purpose enforced at every tool?
What evaluation blocks a model, prompt, data, or tool release?
How does an operator inspect, stop, resume, and roll back work?

Buyer questions

Frequently asked before an engineering engagement.

When should an AI workflow use an agent instead of deterministic automation?

Use an agent when the workflow genuinely requires interpretation or variable planning. Keep known rules, financial calculations, permission checks, and irreversible actions deterministic. Many dependable systems combine an agent for analysis with a state machine for execution.

How do you prevent an agent from using a tool it should not access?

Do not rely on the prompt. Authenticate the user and workload, issue narrowly scoped credentials, authorize each action against policy and current resource state, validate typed inputs, and test denied paths. The tool must reject an unauthorized call even if the model requests it.

Does MCP make an agent secure?

No. MCP provides an integration protocol. Security still depends on server trust, authentication, authorization, data minimization, input and output validation, network controls, and how the host exposes each capability.

Can agents run in a private cloud or VPC?

Yes. Models, retrieval, orchestration, and tools can be placed in public, private, hybrid, or sovereign environments. The choice follows data residency, latency, provider capability, operating maturity, and the actual control boundary.
