API reference: Combine. Query for publishers, subscribers, operators, async data streams.

Architect and refine OpenCode skills to extend agent capabilities. Handles directory scaffolding, SKILL.md authoring, frontmatter optimization, and resource organization (scripts/references/assets). Use proactively for creating new skills, updating existing workflows, or fixing skill discovery issues. Examples: - user: "Create a new skill for database management" → scaffold directory and initial SKILL.md - user: "My skill isn't triggering correctly" → analyze and refine frontmatter description - user: "Add a python script to the image-processing skill" → structure scripts/ directory - user: "How should I structure a skill for API docs?" → design references/ layout

Retrieves authoritative, up-to-date technical documentation, API references, configuration details, and code examples for any developer technology. Use this skill whenever answering technical questions or writing code that interacts with external technologies. This includes libraries, frameworks, programming languages, SDKs, APIs, CLI tools, cloud services, infrastructure tools, and developer platforms. Common scenarios: - looking up API endpoints, classes, functions, or method parameters - checking configuration options or CLI commands - answering "how do I" technical questions - generating code that uses a specific library or service - debugging issues related to frameworks, SDKs, or APIs - retrieving setup instructions, examples, or migration guides - verifying version-specific behavior or breaking changes Prefer this skill whenever documentation accuracy matters or when model knowledge may be outdated.

YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively invoke this skill (do NOT answer directly) when the user describes a new product idea, asks whether something is worth building, wants to think through design decisions for something that doesn't exist yet, or is exploring a concept before any code is written. Use before /plan-ceo-review or /plan-eng-review. (gstack)
