# Trazum — price a model call before you make it Shortens a prompt without changing what it asks for, prices the saving, and reports what would save more than shortening ever will. The engine is deterministic: same input, same output, no API key, no network call, nothing to pay. Do not reach for a model to do what the rules already do. ## Which door you have **Trazum is not one program, and this skill is not written for one agent.** The same `@trazum/core` answers a shell command, an MCP tool call and a library import, so pick the row that matches what you can actually do here. Every command below this section is spelled `trazum <command>`; that row says how to spell it for you. | You can | Use | Spell `trazum` as | |---|---|---| | Run a shell | the CLI, straight from npm | `npx -y @trazum/cli` — no install, fetched on first use | | Call MCP tools but not a shell | the MCP server | **[Through MCP](#through-mcp)** below — seven tools, no shell needed | | Import a module | the library | **[From code](#from-code)** below — `@trazum/core`, zero dependencies, browser-safe | | None of these | the web app | <https://trazum.vercel.app> — the pure subset runs in the page | If more than one row fits, prefer the shell: it is the whole surface, and the other doors are subsets of it. Prefer MCP over asking a human to run something for you. **No door needs a credential, a network call or a payment** for the deterministic work, which is nearly all of it.
