shell-mcp

Ultra-lightweight MCP server for shell execution with session management.

Features

Zero runtime dependencies - All dependencies are dev-only
Persistent shell sessions - Run multiple commands in the same shell context
Background processes - Start long-running commands that continue in the background
One-off commands - Execute single commands without session overhead

Tiny AI Client

A minimalist, zero-dependency OpenAI-compatible streaming client with automatic tool calling.

Features

~1.3KB gzipped - Zero dependencies
Dual API support - Responses (default) and Completions modes
Streaming - Async generator with typed chunks
Tool calling - Inline handlers or callback dispatch

Claude generates this anti-pattern due to shallow pattern matching across incompatible mental models:

Why It's Wrong

Every getter access creates a new computed signal with fresh subscriptions:

obj.fullName; // Creates computed signal #1
obj.fullName; // Creates computed signal #2 (never cleaned up!)

DOM Audit Logger

A little library for auditing DOM modifications.

Features

Tracks DOM modifications (textContent, innerHTML, className)
Extensible audit system for custom operations
Formatted audit trail output
Event-based subscription for real-time monitoring

`computedWithMemo()`

It's computed(), but with a second argument that gets passed each newly returned value in order to produce a string cache key. If you return the same cache key as the previous run of the computed, no update will be performed (no effects, no renders, etc).

JSFiddle Demo

- computed(
-   () => ['an', 'unstable', 'return', 'value'],
- )
