I built inbox.dog and hit diminishing returns stuffing agents with dozens of static tools.Context got noisy, tokens bloated, iteration slowed.So I built Anytool: a single meta‑tool your agent calls to generate exactly the tool it needs, on demand.First run generates + caches the code; subsequent runs are instant.Each tool comes with its own isolated sandbox, ephemeral filesystem, per‑tool KV state, dedicated SQLite DB, per‑user env (USER_), full npm in a Bun container, and outbound fetch for APIs.How I built it: - Frontend: SvelteKit (Svelte 5) - Backend: Cloudflare Workers + Durable Objects - Execution: Bun container, full npm, auto‑install + global cache, no bundling - Storage: R2 for code
