Public projects
agent-skills
A large, auto-updating library of agent skills for Claude Code & Codex — Git/GitHub/Actions, Vercel, Serena, Dolt, DDD & SOLID, cross-platform plugin dev, docs tooling, and agentic best-practices. Every skill refreshes weekly from upstream docs.
JavaScript
anti-compact
Claude Code plugin that intercepts automatic compaction and halts it, generating a structured session handoff instead of lossy compression.
JavaScript
agent-marketplace
My curated marketplace and storefront for every plugin, skill, and tool I ship for Claude Code & Codex CLI — also home to the idea-nursery, where nascent macOS tools and automations incubate before earning their own repo.
TypeScriptagentagent-marketplaceagentic-coding
mcp-exec
Reference implementation of Anthropic's 'Code execution with MCP.' Reuses Claude Code's own sandbox and config to keep intermediate tool output out of the context window on every workflow — up to 99% fewer tokens.
TypeScriptai-agentanthropicclaude-code
idiomatic
Fast, language-abstracted idiom enforcement for AI coding agents and humans — teach via a generated skill, enforce via a sub-100ms autofixing gate. Rust core + Python/Node bindings.
Rustai-agentsast-grepcode-quality
lessons-learned
A Claude Code plugin that automatically captures coding mistakes and injects relevant lessons before tool calls — preventing the same mistakes from happening twice.
