Turn an Agent that works into a product customers trust to keep using

Hast helps product teams organize user tasks, proprietary knowledge, business tools, and human service responsibility into deliverable capabilities, with real-task evaluation, tenant isolation, runtime observability, release gates, and rollback for every version.

Controlled pilot

  1. Task contract defined
  2. Tool permissions isolated
  3. Representative evaluations passed
  4. Human takeover available

The product gap is not demo quality. It is whether every real execution is predictable

Know what the Agent completes and refuses

Turn 'smarter' into a task contract covering inputs, outputs, success, clarification, refusal, and transfer so product, engineering, and service use the same standard.

Knowledge and tools must form a recoverable capability

Retrieval is only the start. Real work needs identity, validation, permissions, idempotency, timeout, retry, result checks, and a fallback when tools fail.

Explain every tenant and version independently

Customer configuration, knowledge, models, and tools change. Teams need to know what a version did, for whom, why it failed, what it cost, and whether it can roll back safely.

Move the essential design and operating work of an Agent product to verifiable deliverables

Every step creates an output product, engineering, service, and customers can review together instead of leaving only prompts, model scores, or one successful demo.

01

Define task contracts and human takeover

Use real user work and failures to set what the Agent completes, confirms, refuses, and transfers to service.

DeliverableTask contract, input-output examples, escalation conditions, owners, and acceptance metrics.
02

Package proprietary knowledge and tools as a capability

Apply tenant identity, validation, and permission constraints and verify success, failure, duplicate execution, and result readback.

DeliverableCapability definition, tool contracts, permissions, failure strategy, and execution record.
03

Use representative tasks for release decisions

Evaluate success, factuality, tool completion, refusal, escalation, latency, and cost against the prior usable version.

DeliverableEvaluation report, failure distribution, regression baseline, risk note, and release decision.
04

Operate tenant versions, quality, and cost

Find tenant-specific quality decline, abnormal tool calls, and cost changes, release fixes gradually, and retain fast rollback.

DeliverableTenant health view, version trace, alerts, rollback record, and improvement queue.

Connect more of the systems behind product delivery

Hast supports customer-authorized connectors across engineering, documents, communication, credentials, and runtime systems while preserving tenant scope.

Product definition and engineering delivery

Turn the product promise into a testable, isolated, recoverable system

Agent products touch real data and actions across tenants. Hast carries identity, capability version, evaluation, and execution records through every run so teams can prove who a version serves, what it can do, and when it must stop.

Tenant identity reaches every retrieval and tool call

Configuration, knowledge, tools, logs, and cache stay bound to tenant and role, including test and debugging work.

  • Agent may complete autonomously — Bounded low-risk tasks with verifiable outcomes and recoverable failure
  • Allowed

Every capability change triggers evaluation

Model, prompt, knowledge, tool, and policy changes run independent regression with quality, safety, latency, and cost differences.

  • Customer or service confirmation required — External send, record write, exception route, and medium-impact action
  • Confirm first

Failure can degrade, transfer, and roll back

Tool failure, insufficient evidence, and risky tasks have stop conditions; human takeover gets full context and bad versions can be withdrawn.

  • Authorized people remain responsible — High-impact decisions, irreversible actions, contractual commitments, and account access
  • Human decision

Start with one task a real customer is willing to hand to the product

Choose bounded input, verifiable output, and a task the service team already knows how to recover, then deliver an end-to-end controlled pilot instead of a universal Agent platform.

Turn one existing service workflow into an Agent capability

Use a repetitive customer task to define the deliverable, failures, takeover, and service level.

Add release gates to one live Agent

Build regression from historical tasks and compare current quality, safety, latency, and cost.

Verify isolated rollout and rollback for one tenant

Test identity across configuration, knowledge, tools, and logs plus anomaly detection and recovery speed.

Use one real customer task to test whether the Agent has become a deliverable product

We will define the task contract, capability boundary, evaluation gates, and operating responsibility with product, engineering, service, and security teams, then scale from customer pilot outcomes.
