Drive a full desktop computer over the iii bus: start a session, see the screen as an image, click, type, and scroll by coordinate, and — on native sessions — read an app's accessibility tree and act on elements by reference. Reach for it when a task needs to…

The iii web console — chat, trace explorer, worker catalog, and the runtime host every worker injects its own pages, renderers, and configuration forms into. Read it before building or changing any console UI, and when an agent must drive the operator's…

Durable cross-session memory: named banks of always-injected markdown rules and auto-extracted memories with hybrid recall. Reach for it when the user asks you to remember, forget, or inspect what is remembered.

File-backed kanban board: create, read, move and comment on tickets by key or uuid, assign agent profiles, and wake on comments through the kanban:comment trigger instead of polling. Group tickets as subtasks and file them under projects and releases. Reach…

Discovery entry point for the engine — search the live function catalog, read the skills, system prompts, and agent profiles that installed workers ship off local disk, browse the public iii workers registry over HTTP, and install new worker bundles and kits…

See and manage the host's tmux sessions and windows from iii: which pane runs Claude Code, Codex or another agent CLI and whether it is working, waiting for the person or idle; which pane runs `iii compose` and on which ports its engine and workers listen;…

Use the WhatsApp worker to manage linked-device sessions, send authorized messages, operate groups, consume events, or use an existing Meta Cloud API account.

DEPRECATED (will be removed in an upcoming release; migration guide https://github.com/iii-hq/iii/blob/6901a589dd39d9c34f9d5b6bd8bc82170ee21548/docs/next/upgrading/migrate-from-streams.mdx). Fire-and-forget topic pub/sub: broadcast an event with `publish` and…

Durable real-time streams with a CRUD function surface plus reactive triggers that fire on item changes and WebSocket subscriber lifecycle — reach for it to build live backends without polling. iii-stream is deprecated (iii-stream) and will be removed in an…

Use when composing iii primitives into backend architectures: durable workflows, reactive backends, observer side effects, agentic pipelines, event-driven CQRS, effect pipelines, and trigger-transform-action automation.

Use when registering iii functions, binding triggers, observing functions, selecting sync/void/enqueue invocation, creating workers, inspecting the live worker registry, installing registry workers, authoring event sources, moving channel data, or adapting…

Configure a managed iii engine through worker-compose.yaml or a directly supervised engine through config.yaml. Use for engine ports, RBAC via the rbac-proxy worker, observer limits, streams, sandboxes, and configuration storage.

Handle iii engine and SDK errors across Node, Python, Rust, and browser workers. Use when interpreting error codes, retryability, RBAC denial, timeouts, handler failures, or SDK-specific exception surfaces.

Install the iii engine, set up your first worker, and get a working backend running. Use when a user wants to start a new iii project, install the SDK, or needs help with initial setup and configuration.

Use when observing iii functions with iii.observe, writing filters, reacting to engine events, writing observable functions with owner delivery (onObserverAdded, obs.emit, obs.call), tuning local dispatch, or migrating from the deprecated registerTrigger /…

Use when working with iii SDK APIs across Node.js, browser, Python, Rust, or Go: package installation, worker initialization, function/trigger registration, observers, invocation, local dispatch, channels, logging, OpenTelemetry, and language-specific caveats.

Skill bundle index for authoring Mintlify-shaped docs that iii-skill-check validates.

Skill bundle index for authoring the partials iii-skill-check renders into a worker README and a single skill.md (leaves inlined as HOWTOs).

Targeted AI-layer fixture for worker concept drift.

Targeted AI-layer fixture for SDK convention drift.

A worker shipped with intentional rule violations for testing the validator.

UI/UX design intelligence. 50 styles, 21 palettes, 50 font pairings, 20 charts, 9 stacks (React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind, shadcn/ui). Actions: plan, build, create, design, implement, review, fix, improve, optimize,…

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js…
