📋 Decision Context

Question:

Session 139 Computer Use: What was the full scope of work delivered?

Task: Session 139 milestone: Computer Use fully operational

🎯 Decision Made

Chosen:

End-to-end Computer Use system: E2B Desktop persistent sandboxes, Playwright fallback with lifecycle fix, robotjs desktop control, 9 service profiles, mid-session reply, Chrome enforcement, dynamic tool versioning, centralized LLM config, self-hosted infrastructure plan for S140

Options Considered:

• No alternatives documented

💭 Reasoning

Session 139 took Computer Use from completely broken (sessions never appeared in UI) to fully functional (Gmail login + compose + send in 23 steps, ~3 minutes). Key milestones: (1) Fixed non-blocking executeGoal so sessions appear in UI immediately. (2) Fixed model ID from non-existent claude-sonnet-4-5-20251022 to correct claude-sonnet-4-6 with dynamic computer_20251124 tool selection. (3) Added system prompt authorizing Claude to use credentials and interact with communications platforms. (4) Integrated E2B Desktop as primary execution engine with persistent per-user sandboxes (30min idle TTL). (5) Added service profiles with suggested tasks, credential validation, and systemPromptHint per service. (6) Built mid-session reply for 2FA codes. (7) Enforced Chrome over Firefox in E2B sandboxes. (8) Migrated desktop control from unmaintained cliclick to @jitsi/robotjs. (9) Fixed Playwright page/context leaks (session-scoped agentId + cleanup in finally block). (10) Centralized all hardcoded LLM model IDs into ai-models.config.ts. (11) Wrote comprehensive self-hosted E2B infrastructure plan for S140 (Hetzner $46/mo, custom Firecracker images, unlimited sessions).
