MasterMindMandan - Field Report

You're running 2.1.37 but BEST-PRACTICES.md documents up to 2.1.34. New features include agent teams polish, Task tool metrics, and mTLS proxy fixes. Update documentation to reflect current version.

Last upgrade check: 2026-02-03. Run winget upgrade --all to catch any Claude Code, Codex, or Gemini CLI patches from the past week.

OX Security found 94 unpatched Chromium CVEs in both Cursor and Windsurf, affecting 1.8M developers. If Commander uses either IDE, update immediately or evaluate risk.

Open-source Gemini CLI extension that stores developer context as versioned Markdown files. Replaces ephemeral chat with persistent context directories -- think CLAUDE.md but for Gemini, with specification/planning/implementation phases and human checkpoints. Interesting pattern to evaluate.

Submit messages while Codex is executing to redirect behaviour mid-task. Enter sends immediately during running tasks, Tab queues follow-up. Shell tools now run in parallel. Useful competitive feature Claude Code doesn't yet offer.

Output limit doubled from 64K to 128K on Opus 4.6. For long-form generation tasks (reports, full documents, large code blocks), this removes a major constraint. Already active on Commander's model.

Bun.SQL provides a unified API for MySQL/Postgres/SQLite with zero deps. HTML files can be served directly with built-in HMR and React Fast Refresh. Significant for rapid prototyping.

Developers found references to "Fennec" (Claude Sonnet 5) in Google Vertex AI logs. No official confirmation from Anthropic, but signals are strong. Would be a significant Sonnet-tier upgrade if pricing stays at Sonnet level.

Structured outputs parameter moved from output_format to output_config.format. Any API code using structured outputs should be updated.

Enterprise-grade agent deployment for trade accounting and client onboarding. Validates the agent architecture patterns Commander is using in CORTEX/PCC.

Using out-of-the-box capabilities, Opus 4.6 uncovered 500+ previously unknown flaws in open-source code, all validated by researchers. Reinforces value of the security-auditor subagent pattern.

Windsurf now supercharged by the Devin team. Continues to operate independently. Watch for integration of Devin's autonomous agent into Windsurf IDE.

claude-3-opus-20240229 now returns errors. Any legacy references should be removed. Commander's systems already on Opus 4.6.
