Developer tools
Small, single-purpose tools that do one thing to something you already have. Whatever you paste stays in the tab, never reaches a server, and no tool here asks for an email.
AGENTS.md generator
Turns a short form into a root AGENTS.md with your stack, the exact commands that prove a change works, hard constraints, and a session continuity protocol.
Claude Code cost calculator
Estimates API and eligible Agent SDK costs from Anthropic's published token prices, with every workload assumption visible and editable.
MCP config validator
Checks your mcp.json for missing commands, duplicate server names JSON silently drops, secrets pasted into env, and variable references that never expand.
