From 0a0ed05e075259dc6ddb3d8f1c4d3ac466bce34d Mon Sep 17 00:00:00 2001 From: TomTang Date: Thu, 28 May 2026 14:55:23 +1000 Subject: [PATCH 1/8] feat: replace Slack with Lark for approval notifications MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace SlackClient/SlackNotifier with LarkClient/ApprovalNotifier using Lark's tenant_access_token + interactive card API - Replace SlackWebhookHandler with LarkWebhookHandler at POST /lark/actions with SHA-256 signature verification and URL challenge support - Add examples/mock-lark for local testing (replaces mock-slack) - Update config env vars: SLACK_* → LARK_APP_ID/APP_SECRET/CHAT_ID/VERIFICATION_TOKEN - Expose postgres:5432 and redis:6379 host ports in docker-compose -

Slack → Lark migration (gateway + eval runner): - Rename all Slack references to Lark throughout gateway config, webhook handler, policy gate, approval bridge, stack health, and tests - Add LARK_APP_ID / LARK_APP_SECRET / LARK_CHAT_ID / LARK_VERIFICATION_TOKEN env vars; remove SLACK_* vars from config and docker-compose files - Implement LarkNotifier in slack_webhook.go using Lark Open Platform APIs (tenant_access_token + im/v1/messages); keep HMAC signature verification for inbound callbacks on /lark/actions - Update mock-lark example server and mock-slack to match new Lark API shape - Update deploy/docker-compose.yml with mock-lark service and Lark env vars Fix approval-timeout eval scenario: - Add Lark reachability precondition check to approval-timeout scenario: fails fast with a clear message if mock-lark is still up (mirrors the existing MCP-crash precondition pattern); mock-lark auto-approves every ticket so the scenario can never reach 'expired' while it is running - Add APPROVAL_TIMEOUT=25s to root docker-compose.yml gateway service (was missing; deploy/docker-compose.yml already had it); without this the 5-minute default outlasts the eval runner's 90s poll window - Wire STACK_HEALTH_SLACK_URL → scenarioDeps.larkURL in serve.go so the precondition probe uses the same address as the stack health check - Update UI scenario description from "Slack is down" to "Lark is down" localstripe_demo submodule (d652019): - Bump to commit that fixes approval-flow race conditions in demo webapp: emit SSE done only after full event stream exhaustion, handle late-arriving tool_end badges, discourage dry_run=True in agent prompt and MCP docstring Co-Authored-By: Claude Sonnet 4.6 --- cmd/eval-runner/runner.go | 2 +- cmd/eval-runner/scenarios.go | 89
