MasterMindMandan - Field Report

Cursor, Windsurf, and Google Antigravity were recommending non-existent extensions from OpenVSX registry, allowing attackers to claim namespaces and upload malicious code. Cursor fixed Dec 2025, Google fixed Jan 1, 2026. Verify your extensions are from trusted sources.

Model was shut down on January 15, 2026. If you have any integrations using this model, migrate immediately to Gemini 3 Flash.

Bun.SQL - unified API for MySQL, MariaDB, PostgreSQL, SQLite with zero dependencies. Zero-config frontend - run HTML files directly with HMR and React Fast Refresh built-in. bun update --interactive for selective dependency updates. Response.json() is 3.5x faster, 15% faster async/await.

Agent Skills - reusable instruction bundles invoked with $skill-name syntax. Web search - Codex can now search the internet for docs and solutions. SKILL.toml metadata for skill config. Multi-conversation agent control for spawning/messaging other conversations.

New agentic coding model optimized for long-horizon context, big refactors, Windows performance, and cybersecurity. Now the default model for Codex CLI and IDE extensions.

Built-in skill-creator and pr-creator skills. Dynamic mode-aware policy evaluation. Refined Gemini 3 system instructions to reduce model verbosity.

Pro-grade reasoning at Flash-level speed and lower cost. Available via Gemini API, Google AI Studio, Vertex AI, Gemini CLI, and Android Studio. Good for coding, complex analysis, and interactive apps.

File size limit increased from 20MB to 100MB. Now supports Cloud Storage buckets and pre-signed URLs as data input sources.

SWE-bench: Antigravity 76.2%, Cursor ~77%, Windsurf similar. All significantly outperform standalone models. Antigravity's "Manager View" runs 5 parallel agents with Chrome integration.

Anthropic seeking $10B funding at $350B valuation. Revenue grew from $1B to $5B+ in eight months. "Do more with less" strategy focusing on algorithmic efficiency over raw compute.

OAuth-based wrappers that pilot Claude Pro/Max accounts for automation are being actively blocked. Ensure any automation uses official APIs, not consumer account automation.

Billing for Grounding with Google Search began January 5, 2026. Factor into cost projections if using this feature.
