What a digital expert can access in a group should be configured by administrators, rather than varying with the individual who asked. ## Current Access Foundation | Capability | Status | Notes | | ------------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | IM integration credentials | Available foundation | [Lark](../plugin/integration/lark-integration), [DingTalk](../plugin/integration/dingtalk-integration), and [WeCom](../plugin/integration/wecom-integration) credentials are stored and used through system integrations. | | Trigger binding | Available foundation | Triggers bind an IM integration to a target digital expert. | | Digital expert runtime identity | Available foundation | Digital experts execute through existing platform runtime and workflow permissions. | | Toolset authorization | Available foundation | Toolsets, knowledge bases, and business plugins use current Xpert access models. | | Webhook authentication | Available foundation | Plugins protect inbound routes with guards, signatures, tokens, or encrypted callbacks. | | Group-level Access Bundle | Planned | There is no cross-IM group capability package model yet. | | Unified Tag audit | Planned | There is no single Tag-session-centered audit page yet. | | Credential Proxy | Planned | There is no unified credential proxy with default-deny egress yet. | ## Group-Level Access Bundle Access Bundle is the most important future governance object for Xpert Tag. It should package reusable capabilities and bind them to an organization, IM workspace, group, or channel. | Configuration | Example | Status | | -------------------- | --------------------------------------------------------------------------- | ------- | | Knowledge scope | Company policies, project materials, product docs. | Planned | | Toolsets and plugins | Ticketing, CRM, BI, code platform, approval, documents. | Planned | | Business credentials | Service-account API keys, OAuth clients, read-only database accounts. | Planned | | Allowed domains | API hosts, document hosts, code platform hosts. | Planned | | Default instructions | Output format, risk notes, citation requirements, forbidden content. | Planned | | Write policy | Read-only, confirmation required, approval required, or auto-write allowed. | Planned | | Model policy | Default model, allowed model switching, cost limits. | Planned | | Budget and usage | Group budget, daily limits, anomaly alerts. | Planned | Recommended bundle patterns: * `project-readonly`: project knowledge, read-only docs, read-only tickets. * `support-triage`: support knowledge, ticket creation, customer-state lookup. * `bi-readonly`: semantic metrics and read-only data queries. * `code-review`: repository read, PR comments, CI state read. * `code-write`: repository write and PR creation, approval required by default. ## Service Account Principle The target Xpert Tag identity model is: shared group work uses administrator-configured service accounts or platform technical users by default, not the requester’s personal credentials. | Scenario | Recommended identity | Status | | ----------------------------------- | ----------------------------------------------------- | -------------------- | | IM send/receive | IM bot application identity. | Available foundation | | Digital expert background execution | The platform runtime identity for the target expert. | Available foundation | | Business-system read/write | Dedicated service account or governed API credential. | Partially available | | Personal private tasks | User personal connections and permissions. | Planned | Service accounts provide: * Consistent group capabilities regardless of who asked. * Clear external audit logs showing what the Xpert Tag service account did. * Central revocation, rotation, and scope reduction without affecting personal accounts. * Central confirmation, approval, and risk limits for write operations. ## Credentials And Network Egress Today, plugins and tools use credentials through existing Xpert integration and tool mechanisms. Xpert Tag should add a unified Credential Proxy. | Capability | Goal | Status | | -------------------------------- | ------------------------------------------------------------------- | ------------------- | | Write-only credentials | Do not show saved secret values again. | Partially available | | Boundary credential injection | Inject credentials only at a controlled runtime boundary. | Planned | | Default-deny network egress | Block hosts not allowed by bundle or environment. | Planned | | Host/path/method controls | Restrict exact APIs the agent can reach. | Planned | | Credentialless allowlist | Allow public hosts without injecting credentials. | Planned | | Internal and metadata protection | Block private networks, metadata services, and sensitive addresses. | Planned | ## Audit Requirements Unified Tag audit is `Planned`. The target audit record should include at least: * Source platform, group, DM, thread, and message ID. * Triggering user, visible member scope, and digital expert. * Effective Access Bundle, model, knowledge bases, tools, and skills. * Input summary, attachment summary, and context sources. * Tool name, parameter summary, result summary, and errors. * Write confirmation, approval status, and external record IDs. * Output summary, artifact links, and final status. * Token usage, cost, duration, and retry records. ## Risk Controls Xpert Tag should include these built-in controls: | Risk | Control | Status | | --------------------------------------------- | ------------------------------------------------------------------- | ------------------- | | Group members overreach into business systems | Group-level Access Bundle and least-privilege service accounts. | Planned | | Sensitive output posted to a large group | Sensitive filters, pre-send checks, group-level forbidden content. | Partially available | | Accidental write operations | Confirmation, approval workflow, read-only defaults, rollback logs. | Partially available | | Long task runs away | Cancel button, budget limits, timeout, retry limits. | Partially available | | Plugin credential leak | Write-only credentials, proxy injection, redacted logs. | Partially available | | Audit gaps | Unified Tag session audit. | Planned | ## Recommended Defaults Before full Xpert Tag productization, pilot with conservative defaults: * Group chats respond only to explicit bot mentions by default. * Group history reading is off by default and enabled explicitly per group. * Write operations require human confirmation by default. * High-risk tools start read-only. * New bundles are first attached to private pilot groups. * [WeCom](../plugin/integration/wecom-integration) should degrade according to platform capability instead of promising full parity with other platforms.
