Workers, agent kits, and tools for the iii engine.
Pick your pieces. Make something great.
THE REGISTRY
Explore the workers, kits, and tools developers are building with.
Distributed key-value state management — registers the `state::*` functions and `state::on-changed`, a private function observers watch for every committed change.
iii trigger compose::add worker=stateExpose functions as HTTP endpoints — hosts `http::on-request`; each observer of it declares a route, and its target answers the matched requests.
iii trigger compose::add worker=httpRoutes sandbox::* in the default namespace to the configured sandbox adapter worker (sandbox-libkrun by default).
iii trigger compose::add worker=iii-sandboxDurable function queues - hosts `queue::on-message`, which topic subscribers observe, and the queue/DLQ service functions.
iii trigger compose::add worker=queueRun functions on cron schedules — hosts `cron::on-tick`; each observer of it passes `{ expression }` as args and receives that expression's ticks.
iii trigger compose::add worker=cronOne front door + provider protocol in front of every LLM provider.
iii trigger compose::add worker=llm-routerEngine introspection, workers registry proxy, filesystem-backed skills, system prompts, and agent profiles, kit install and update with reviewed plans, plus function search ranked by the judge worker (falling back to local hybrid/lexical) with a conditional pre-generate hint.
iii trigger compose::add worker=iii-directoryTalk to PostgreSQL, MySQL, and SQLite from iii — query, execute, transactions, prepared statements, and database::on-row-changed for observing committed writes.
iii trigger compose::add worker=databaseDurable, reactive, branching store of typed conversation entries with six observable session event functions.
iii trigger compose::add worker=session-managerMeasure Harness capability, retain reproducible evidence, and expose the E2E dashboard.

Checkout failed because the payment retry was never awaited. I reproduced it in a sandbox, patched it, and opened PR #512. The tests pass.
Sample session: the prompt “Checkout is failing on staging. Find out why and open a fix.” runs directory::search_functions, which finds five functions in 3 milliseconds. The harness then calls browser::navigate, sandbox::exec, router::chat, state::set and github::pr::create through iii, and replies: Checkout failed because the payment retry was never awaited. I reproduced it in a sandbox, patched it, and opened PR #512. The tests pass.
