Build Log

Things I've Built

A log of features, tools, and projects I've shipped that I'm proud of and can share.

Deep Mode
with Hitesh
Tuned prompts for GPT-5.2-Codex, built custom tools, made tool execution async, and added auto-compaction.
Jan 2026
Handoff as a Tool
Made handoff invokable by the agent. Added natural language detection so the agent can handoff when asked.
Jan 2026
Efficient MCP Tool Loading
Made skills carry MCP servers with lazy loading. Tools only load when the skill is called. Reduced chrome-devtools from 17k to 1.5k tokens.
Jan 2026
User Invokable Skills
Added skill invocation to the command palette. Users can now trigger skills directly instead of waiting for the agent to pick them.
Jan 2026
Command Palette
with Lewis
Built the command palette UI and wired up commands. Replaced memorizing slash commands with searchable actions.
Oct 2025
Handoff
Built handoff to replace lossy compaction. Extracts relevant context for the next task and generates a focused prompt for the new thread.
Oct 2025
Custom Slash Commands
Built the slash command system for custom prompts. Supports static text, dynamic generation via scripts, and shebang notation.
