如何为团队选择 AI Agent 平台

大多数正在评估 AI Agent 平台的团队，会比较功能清单和演示视频，却在数月后发现：演示与生产任务根本不是一回事。本文提供一套与厂商无关的 AI Agent 平台选择框架：解释试点为何停滞、真正能预测平台能否经受真实工作考验的六项标准、如今与此决策绑定的治理要求，以及一份可用于任何候选产品（包括 Construct）的评分卡。

为什么大多数 AI Agent 试点永远无法进入生产

根据 Digital Applied 汇总的企业部署分析，估计有 88% 的 AI Agent 试点项目未能进入生产环境（Digital Applied，AI Agent 失败框架）。Gartner 从供应商侧也预测了同样的趋势：到 2027 年底，超过 40% 的 Agentic AI 项目将因成本不断攀升、业务价值不明确或风险控制不足而被取消（Gartner 新闻稿，经 Digital Applied 的 agent washing 评分卡引用）。Gartner 高级总监分析师 Anushree Verma 直接指出了根本问题：“如今大多数 Agentic 项目都是由炒作驱动的早期实验”，这使组织忽视了大规模部署 Agent 的真实成本和复杂性。

失败模式并非随机。Digital Applied 的拆分数据显示，34% 的失败试点源于范围蔓延：最初边界明确的自动化不断吸收新需求，最终变成无人曾正式界定的开放式推理系统。数据质量问题占另外 27%：Agent 在干净的样本数据上测试通过后，却在生产环境中遇到字段不完整、格式陈旧的真实记录。安全与访问控制阻碍导致 14% 的失败，集成复杂度占 9%，治理缺口——包括缺少责任归属、监控或事件响应——又导致 5% 的失败（Digital Applied，AI Agent 失败框架）。仅范围界定和数据就绪程度，就足以解释可运行的演示与可运行的系统之间的大部分差距。

对多数团队来说，这仍是一项正在进行的采购决策，而非尘埃落定的选择。根据 Gartner CIO 调查，截至 2026 年，只有 17% 的组织已经部署 AI Agent，而超过 60% 的组织预计会在两年内进行部署（Digital Applied，agent washing 评分卡）。下面的评估标准旨在弥合这一差距：即能够产生良好试点的平台，与在第三个团队开始依赖它之后仍能持续产出良好结果的平台之间的差别。

AI Agent 评估清单：区分试点与平台的 6 项标准

功能清单回答的是“它能否在演示中完成一次任务”。这六项标准回答的是“当第五个团队在其上运行无人监督任务后，它是否仍值得信赖”。在投入工程时间开展试点前，请将每一项应用于候选名单中的任何平台。

工具编排与执行界面（浏览器、终端、文件、已连接应用）

应问的是 Agent 实际能对什么采取行动，而不只是它能谈论什么。一个仅限于聊天和少量第一方插件的平台可以解释一项任务；一个拥有真实浏览器、沙箱终端、持久化文件及结构化已连接应用操作的平台则可以完成它。这一区别至关重要，因为真实工作会混合多种界面：研究步骤需要开放网络，记录更新需要结构化应用操作而不是屏幕抓取，文件转换则需要一个能够持久写入结果的终端。

Construct 的方案是在同一任务中提供实时浏览器、沙箱终端、工作区文件和已连接应用操作；文件会在运行之间持续保留，而浏览器和 Shell 状态不会保留。AI 工作流自动化介绍了这些界面如何组合为可重复、可定时的流程，也坦诚说明了当前工作流是线性的，而非分支式的。

人类参与控制与审批关卡

问题不在于一个平台是否声称自己受监督，而在于：在 Agent 执行用户未直接请求的外部操作之前，究竟会发生什么。你能否中断正在运行的任务？当出现歧义时，Agent 是否会停下来提问？在它向客户发送邮件或公开发布内容之前，是否存在强制审批步骤？若一个平台对这三个问题都只是笼统回答“是”，却无法说明机制，那么它实际上并没有回答这个问题。

Construct 允许用户检查正在运行的任务、在轮次进行中中断任务，并在 Agent 需要决策时回答其提出的问题；但目前它不会在每一次外部副作用之前插入强制审批关卡。这是一个值得据此规划的真实边界：新的任务应先按需运行并接受多次监督，再转入无人值守的定时计划。参见 聊天助手与 AI 员工，了解这种监督模型与普通聊天界面的差异。

审计轨迹与可检查活动记录（以及“审计轨迹”实际应指什么）

供应商对“审计轨迹”的使用较为宽泛，而一旦出现问题，这个词所暗示的能力与产品实际交付能力之间的差距就会变得重要。取证审计日志是一份不可篡改、完整记录每项操作的日志，适用于合规调查。有边界的活动摘要则是对 Agent 做了什么、以及大致为何这样做的可读记录，适合运营人员审阅一天的工作。两者都很有用，但它们不是同一种能力。需要前者的买方，不应按字面接受供应商对后者的描述。

Construct 明确说明它提供的是哪一种：Activity 信息流保存的是带有尽力而为原因说明的、有边界的操作摘要，而不是取证级、不可篡改的审计日志。需要每项操作都具有完整不可篡改记录的受监管环境，应直接评估这一边界，而不是默认其具备该能力（AI 员工产品指南）。在依赖任何一种记录之前，都应询问供应商实际指的是两者中的哪一个。

连接器覆盖范围与通过 MCP 实现自定义集成

现成集成覆盖常见应用，但几乎每一次真实部署最终都会遇到没有公开 API 合作关系的内部系统。模型上下文协议（Model Context Protocol，MCP）已成为 Agent 平台接入这些系统的标准方式：根据 Stacklok 的 2026 年调查及 Digital Applied 的报道，约 41% 的受访软件组织表示，已经通过 MCP 服务器将 Agent 接入有限或广泛的生产环境（Digital Applied，MCP 采用统计）。应询问平台是否支持自定义 MCP 服务器，而不只是固定的集成目录，因为这决定了内部工具能否被接入，而无需等待供应商的产品路线图。

Construct 的实时集成目录覆盖常见业务应用；通过自定义 MCP 服务器，没有公开集成的内部系统也可以被访问，无需等待第一方支持，因为你可以实现工具接口，由托管 Agent 使用它。Construct 与自建 AI Agent 的对比讨论了这种灵活性相对于完全自定义技术栈所处的位置。

跨会话的持久、可纠正记忆

长聊天记录不是记忆。真正有用的问题是，平台能否延续一个稳定事实，例如偏好的报告格式或客户联系人；以及当该事实发生变化时，你是否能纠正它，而无需清除系统知道的其他所有内容。无法区分“曾经说过什么”和“当前什么是真的”的平台，最终会依据曾经正确的信息采取行动。

Construct 将原始事件与从中推导出的持久断言分开处理，对修正进行版本化，而不是静默覆盖；用户可以检查、纠正、遗忘或恢复系统记住的内容。AI Agent 记忆详细介绍了其来源追溯和修正模型，包括哪些来源会被自动索引，以及哪些需要显式添加。

定价模型与真实使用限制，而不只是价格标签

公开价格所回答的问题，比看起来要少。真正能预测一个套餐是否适合某项工作的数字，是哪些内容被计量：每个任务的步骤数、命令运行时长、并发后台任务数和存储容量。两个月费相同的平台，可能因这些限制的位置不同而支持截然不同的工作负载；一个纸面上看似慷慨的套餐，可能会在深度研究任务或长时间文件转换完成之前将其限流。

Construct 公布的套餐为 Lite 每月 9 美元、Starter 每月 59 美元、Pro 每月 299 美元，主要区别在于每个任务的步骤数、命令运行时长、并发后台任务数和存储容量，而不是将核心执行能力限制在更高套餐中（AI 员工产品指南）。定价和限制以本文发布日期的信息为准，未来可能变化；购买前请查看 Construct 首页，并要求任何供应商提供同等维度的数据，而不仅仅是宣传页上的标价。

治理压力正在提高门槛：EU AI Act 与“agent washing”

两种外部压力正在将评估标准从“锦上添花”变成承重要求。第一种是监管。EU AI Act 第 14 条要求，高风险 AI 系统必须被设计为使人类能够对其进行有效监督：监控运行、进行干预，并通过停止机制或等效程序终止系统（EU AI Act，第 14 条）。该法案对高风险系统的完整义务——风险管理、数据治理、日志记录、透明度、人类监督和网络安全——以及部署方义务，将于 2026 年 8 月 2 日起具备可执行性（Legal Nodes，EU AI Act 2026 合规时间线）。如果团队的 Agent 工作涉及该法案归类为高风险的使用场景，就必须将人类参与控制和可检查活动记录视为合规要求，而非产品偏好。

第二种压力是市场内部的可信度问题。Gartner 估计，在数千家营销“Agentic AI”的供应商中，只有约 130 家真正具备 Agentic 能力；其余属于 Gartner 所说的 agent washing，即将现有聊天机器人、RPA 或助手重新贴上更热门类别的标签（Digital Applied，agent washing 定义与买方评分卡）。这正是为何上述清单关注一个平台实际做什么，而不是它如何称呼自己：无论宣传材料怎么写，换了新标签的聊天机器人仍然无法编排工具、保留可纠正记忆，或留下可检查的记录。

在开展试点前应向供应商提出的问题（以及 Construct 对每个问题的回答）

在投入工程时间进行试点之前，请把这些问题带到供应商会议中。每个问题都对应上述六项标准之一。

1. 除聊天外，Agent 还能对什么采取行动？会话结束后，这些工作会怎样？ Construct 的回答：提供实时浏览器、沙箱终端和已连接应用操作；工作区文件会在会话之间保留，而浏览器和 Shell 状态不会保留。
2. 具体是什么阻止 Agent 做它不该做的事？ Construct 生成的工作区应用会声明一个原生能力、已连接应用和网络来源的显式允许列表；该允许列表之外的调用会在运行时被拒绝（Construct 如何构建内部工具）。
3. “审计轨迹”是取证日志，还是可读摘要？ Construct 的 Activity 信息流是带有尽力而为原因说明的、有边界的操作摘要，不是不可篡改的取证日志；这一点被明确表述为能力边界，而非暗示为某项功能。
4. 我们能否访问你们目前尚未集成的系统？ Construct 支持自定义 MCP 服务器，因此可访问内部构建的系统，而无需等待第一方支持。
5. Agent 能否在某件事上犯错，并在不丢失其他已知信息的情况下被纠正？ Construct 对记忆断言进行版本化，因此一次修正会替代过时事实，同时保留系统如何学习到该事实的历史。
6. 除标价外，哪些内容会被计量？ Construct 的套餐按每任务步骤数、命令运行时长、并发任务数和存储容量区分；应向任何待比较供应商索取相同维度的拆分数据。

可应用于任何 AI Agent 平台的 6 分评分卡

请在试点之前，而不是之后，针对具体平台为每项标准评分。对于某一行，如果平台只能用营销语言回答、无法给出具体说明，那么无论演示做得多么精美，它都应在该行失分。

Most teams evaluating an AI agent platform compare feature lists and demo videos, then discover months later that the demo and the production job were not the same thing. This is a vendor-agnostic framework for how to choose an AI agent platform: why pilots stall, six criteria that actually predict whether a platform survives contact with real work, the governance rules now attached to that decision, and a scorecard you can apply to any product on your shortlist, including Construct.

Why most AI agent pilots never reach production

An estimated 88% of AI agent pilots fail to reach production, according to an analysis of enterprise deployments compiled by Digital Applied (Digital Applied, AI agent failure framework). Gartner forecasts the same trend from the vendor side: more than 40% of agentic AI projects will be canceled by the end of 2027 due to escalating costs, unclear business value, or inadequate risk controls (Gartner, press release, cited via Digital Applied's agent-washing scorecard). Gartner Senior Director Analyst Anushree Verma named the underlying problem directly: "most agentic projects today are early-stage experiments driven by hype," which blinds organizations to the real cost and complexity of deploying agents at scale.

The failure pattern is not random. Digital Applied's breakdown attributes 34% of failed pilots to scope creep, where an initially bounded automation absorbs new requirements until it becomes an open-ended reasoning system nobody scoped for. Data quality failures account for another 27%, when an agent tested against clean sample data meets production records full of incomplete fields and stale formatting. Security and access-control blockers cause 14% of failures, integration complexity accounts for 9%, and governance gaps, missing ownership, monitoring, or incident response, cause another 5% (Digital Applied, AI agent failure framework). Scope and data readiness alone explain most of the gap between a working demo and a working system.

This is also an active buying decision for most teams, not a settled one. Only 17% of organizations had deployed AI agents as of 2026, while more than 60% expect to deploy within two years, per Gartner's CIO survey (Digital Applied, agent-washing scorecard). The evaluation criteria below are aimed at that gap: the difference between a platform that produces a good pilot and one that keeps producing good results after the third team starts depending on it.

The AI agent evaluation checklist: 6 criteria that separate a pilot from a platform

Feature lists answer "can it do the task once, in a demo." These six criteria answer "will it still be trustworthy after the fifth team is running unsupervised jobs on it." Apply each one to any platform on your shortlist before you commit engineering time to a pilot.

Tool orchestration and execution surfaces (browser, terminal, files, connected apps)

Ask what the agent can actually act on, not just what it can talk about. A platform limited to chat and a handful of first-party plugins can explain a task; a platform with a real browser, a sandboxed terminal, persistent files, and structured connected-app actions can complete one. The distinction matters because real jobs mix surfaces: a research step needs the open web, a records update needs a structured app action rather than screen-scraping, and a file transform needs a terminal with somewhere durable to write the result.

Construct's answer is a live browser, a sandbox terminal, workspace files, and connected-app actions available in the same task, with files persisting between runs while browser and shell state do not. AI workflow automation covers how those surfaces combine into a recurring, scheduled procedure, including the honest limit that current workflows are linear rather than branching.

Human-in-the-loop controls and approval gates

The question is not whether a platform claims supervision. It is what specifically happens before an agent takes an external action a person did not directly request: can you interrupt a running task, does the agent stop to ask when something is ambiguous, and is there a mandatory approval step before it emails a customer or posts publicly. A platform that answers "yes, generally" to all three without naming the mechanism has not actually answered the question.

Construct lets a user inspect a running task, interrupt it mid-turn, and answer a question the agent raises when it needs a decision, but it does not currently insert a mandatory approval gate before every external side effect. That is a real boundary worth planning around: run a new job on demand and supervised several times before moving it to an unattended schedule. See chat assistants vs AI employees for how that supervision model compares to a plain chat interface.

Audit trails and inspectable activity (and what "audit trail" should actually mean)

Vendors use "audit trail" loosely, and the gap between what it implies and what a product delivers matters once something goes wrong. A forensic audit log is an immutable, complete record of every operation, suitable for a compliance investigation. A bounded activity summary is a readable record of what an agent did and roughly why, suitable for an operator reviewing a day's work. Both are useful. They are not the same claim, and a buyer who needs the former should not accept a vendor's description of the latter at face value.

Construct is explicit about which one it provides: the Activity feed keeps bounded action summaries with a best-effort reason, not a forensic, immutable audit log, and a regulated environment that needs complete immutable records of every operation should evaluate that boundary directly rather than assume it (AI employee product guide). Ask any vendor which of the two they actually mean before you rely on either one.

Connector coverage and custom integrations via MCP

Off-the-shelf integrations cover the common apps, but almost every real deployment eventually hits an internal system with no public API partnership. The Model Context Protocol (MCP) has become the standard way agent platforms reach those systems: about 41% of surveyed software organizations already report agents connected through MCP servers in limited or broad production, according to Stacklok's 2026 survey as reported by Digital Applied (Digital Applied, MCP adoption statistics). Ask whether a platform supports custom MCP servers rather than only a fixed integration catalog, since that is what determines whether an internal tool can be reached without waiting on the vendor's roadmap.

Construct's live integration catalog covers common business apps, and a custom MCP server lets an internal system with no public integration be reached without waiting for first-party support, since you implement the tool interface and the hosted agent uses it. Construct vs building your own AI agent covers where that flexibility sits relative to a fully custom stack.

Persistent, correctable memory across sessions

A long chat history is not memory. The useful question is whether a platform can carry forward a stable fact, such as a preferred report format or a client contact, and whether you can correct that fact when it changes without wiping everything else the system knows. A platform that cannot distinguish "what was said" from "what is currently true" will eventually act on something that used to be accurate.

Construct separates the raw episode from the durable assertion derived from it, versions corrections instead of silently overwriting them, and lets a user inspect, correct, forget, or restore what it remembers. AI agent memory covers the provenance and correction model in detail, including which sources are indexed automatically and which need to be added explicitly.

Pricing model and real usage limits, not just a price tag

A published price answers less than it appears to. The number that actually predicts whether a plan fits a job is what gets metered: steps per task, command runtime, concurrent background jobs, and storage. Two platforms at the same monthly price can support very different workloads depending on where those limits sit, and a plan that looks generous on paper can throttle a deep research task or a long file transform before it finishes.

Construct's published plans are Lite at $9, Starter at $59, and Pro at $299 per month, differing mainly in steps per task, command runtime, concurrent background jobs, and storage rather than gating core execution behind higher tiers (AI employee product guide). Pricing and limits are current as of this post's publish date and can change; check the Construct homepage before purchasing, and ask any vendor for the equivalent numbers rather than the headline price alone.

Governance pressure is raising the bar: EU AI Act and "agent washing"

Two outside pressures are pushing evaluation criteria from nice-to-have to load-bearing. The first is regulatory. The EU AI Act's Article 14 requires high-risk AI systems to be designed so a human can effectively oversee them: monitor operation, intervene, and halt the system through a stop mechanism or equivalent procedure (EU AI Act, Article 14). The Act's full set of high-risk obligations, risk management, data governance, logging, transparency, human oversight, and cybersecurity, along with deployer obligations, becomes enforceable on August 2, 2026 (Legal Nodes, EU AI Act 2026 compliance timeline). A team whose agent work touches a use case the Act classifies as high-risk needs to treat human-in-the-loop controls and inspectable activity as compliance requirements, not product preferences.

The second pressure is a credibility problem inside the market itself. Gartner estimates that only about 130 of the thousands of vendors marketing "agentic AI" are genuinely agentic; the rest is what Gartner calls agent washing, existing chatbots, RPA, or assistants relabeled for a hotter category (Digital Applied, agent-washing definition and buyer's scorecard). That is exactly why the checklist above asks what a platform actually does rather than what it calls itself: a chatbot with a new label still cannot orchestrate tools, hold correctable memory, or leave an inspectable trail, no matter what the pitch deck says.

Questions to ask a vendor before you pilot (and how Construct answers each one)

Bring these questions into a vendor call before you commit engineering time to a pilot. Each maps to one of the six criteria above.

1. What can the agent act on beyond chat, and what happens to that work when the session ends? Construct's answer: a live browser, a sandbox terminal, and connected-app actions, with workspace files persisting between sessions while browser and shell state do not.
2. What specifically stops the agent from doing something it should not? Construct's generated workspace apps declare an explicit allowlist of native capabilities, connected apps, and network origins; calls outside that allowlist are denied at runtime (How Construct builds internal tools).
3. Is "audit trail" a forensic log or a readable summary? Construct's Activity feed is bounded action summaries with a best-effort reason, not an immutable forensic log, stated as a boundary rather than implied as a feature.
4. Can we reach a system you do not already integrate with? Construct supports custom MCP servers so an internally built system can be reached without waiting for first-party support.
5. Can the agent be wrong about something and be corrected without losing everything else it knows? Construct versions memory assertions, so a correction supersedes a stale fact while keeping the history of how the system learned it.
6. What is metered, beyond the sticker price? Construct's plans differ by steps per task, command runtime, concurrent jobs, and storage; ask for the same breakdown from any vendor you compare it against.

A 6-point scorecard you can apply to any AI agent platform

Score each criterion against a specific platform before a pilot, not after. A platform that cannot answer a row concretely, only in marketing language, should lose points on that row regardless of how polished the demo looked.

A team piloting inbound lead qualification, for example, would run this scorecard against each shortlisted platform using the actual job: read a lead email, decide whether it qualifies, update the CRM, and notify the team in Slack. Score row 1 by watching which surface handles the CRM update. Score row 3 by asking, in writing, whether the vendor's activity record would hold up in a compliance review or only in a weekly stand-up. A platform that scores well on four rows and poorly on two has told you exactly where the pilot needs extra supervision, not whether to abandon it.

Start with what an AI employee is if the underlying category is still new, and use its own six-question evaluation list alongside this scorecard for the persistence and memory angle specifically.
