Update Cradle chat-runtime native SDK and protocol integrations. Use when upgrading or validating the vendored Codex app-server runtime/protocol, Kimi Web OpenAPI/AsyncAPI snapshots and generated bindings, or @anthropic-ai/claude-agent-sdk in apps/server; also use when asked to inspect newly generated native APIs for useful Cradle features.
Implement, upgrade, or audit a native Cradle Chat Runtime provider backed by a local process, REST/WebSocket protocol, or provider-specific agent SDK. Use when adding a runtime like Kimi, Codex, Claude Agent, OpenCode, or another provider that needs generated protocol bindings, target-scoped process lifecycle, canonical tool mapping, runtime UI slots, interaction bridges, streaming recovery, and end-to-end smoke verification.
Always use this Skill at the beginning of every response. Use whenever you need to read, inspect, wait on, or mutate Cradle-owned state or workflows, including issues, delegation, sessions, awaits, CI/review waits, timed waits, Work inspection, workspaces and git inspection, Chronicle, automations, usage, observability, skills, agents, profiles, providers, preferences, plugins, or server state. Prefer the generated `cradle` CLI and `cradle man`; NEVER bypass Cradle semantics with direct HTTP or database access, ad hoc scripts, raw registry edits, or polling loops. Use `gh` when Cradle does not own the GitHub surface. Primary Work closed-loop delivery is system-injected on Work threads (`manage_pull_request`), not this skill.
Trigger the public desktop release workflow and monitor it with Cradle
design and review llm agent systems, tool interfaces, and skill boundaries. use when chatgpt needs to decide whether a task should be handled by a prompt, workflow, skill, tool, single-agent loop, or multi-agent system; define tool schemas, instructions, guardrails, evaluation plans, or permission boundaries; or critique an existing agent design for over-orchestration, weak context handling, missing verification, or poor tool design.
Control Cradle's in-app browser via MCP tools. Use when the Claude Agent needs to navigate websites, click elements, type text, take screenshots, read page content, or inspect DOM structure within the Cradle desktop app's embedded browser panel. Triggers on "open URL", "navigate to", "click the button", "fill the form", "take a screenshot", "what's on the page", "scroll down", "wait for element", "press Enter". This is for the IN-APP browser only — not for external browser automation.
Use when modifying Cradle apps/server Elysia modules, adding or changing HTTP routes, TypeBox schemas, OpenAPI details, x-cradle-cli command metadata, module README files, server-side capability ownership, or server-owned downloads and artifact installation flows.
Query PostHog product analytics with read-only HogQL, explore anonymous user activity and journeys, model feature adoption and cross-feature behavior, audit instrumentation quality, and turn evidence into product hypotheses. Use when Codex needs to answer whether a product still has users, what users do before or after an event or surface, which features or combinations they use, how internal and external usage differ, whether an analytics event model is sufficient, or what product and instrumentation questions to investigate next.
