CCPP STL
Typed code templates, found in plain English and rendered without touching the context.
A cloud library of typed, composable code templates. Claude searches it in natural language, fills the props and slots, and the server renders the code deterministically, so the output never enters the context.

CCPP Limits protects the context from what tools print. CCPP STL protects it from what the agent writes. Instead of generating the same scaffolding for the hundredth time, Claude finds the template, passes its values, and gets a file rendered on the server.
Why it matters
Typed and composable
Templates declare their props and their slots, and each slot the kind of template it accepts. Compositions are checked before they render.
Found in plain English
Search is semantic. Each slot becomes a search of its own, filtered by the kind it accepts.
Complete, and proven
A library tracks every item of the API it covers. Coverage is computed, and every example is rendered and compiled.
How it works
Search, then render. The rendered code is written to disk by the harness; only its path and size come back.
local stl = require("stl")
local hit = stl.search("a Paper command that heals the player", {limit = 1}).matches[1]
return stl.render({template = hit.template.name, props = {name = "heal"}}).codeSpecifications

Works well with CCPP STL
Every productCCPP Lua
The harness Claude Code was missing: one Lua chunk does a whole step of work.
ccpp shell
One Bash, the same on every operating system, with its core commands written in Go.
CCPP Limits
No tool result reaches the agent whole, and every token a session spends is measured.
One account. Every tool Claude needs.
Free products come with a free account. Builder unlocks the rest, the harness first.
