'Core Principles:'
error-message-explainer
by wedsamuel1230
Interprets Arduino/ESP32/RP2040 compiler errors in plain English for beginners. Use when user shares error messages, compilation failures, upload problems, or asks "what does this error mean". Covers common errors like undefined references, type mismatches, missing libraries, and board-specific issues.
typescript-coding-standards
by williamzujkowski
TypeScript coding standards covering strict type system, advanced types, decorators, generics, and best practices for type-safe applications. Use for TypeScript projects requiring robust type safety and maintainable code.
mcp-installer
by IgorWarzocha
Find, install, and configure MCP servers. Use proactively for MCP discovery, OAuth setup, env vars, stdio vs SSE transport, or troubleshooting MCP connections. Examples: - user: "Add the filesystem MCP server" → read server file, add to mcpServers in opencode.json, verify transport type - user: "How do I use MCP with GitHub?" → check catalog, install @modelcontextprotocol/server-github, configure OAuth token - user: "MCP not connecting" → check transport type (stdio/SSE), verify args/command, check env vars are passed - user: "What MCPs are available?" → run list_mcps.py, show catalog with auth types and install commands
opencode-config
by IgorWarzocha
Edit opencode.json, AGENTS.md, and config files. Use proactively for provider setup, permission changes, model config, formatter rules, or environment variables. Examples: - user: "Add Anthropic as a provider" → edit opencode.json providers, add API key baseEnv var, verify with opencode run test - user: "Restrict this agent's permissions" → add permission block to agent config, set deny/allow for tools/fileAccess - user: "Set GPT-5 as default model" → edit global or agent-level model preference, verify model name format - user: "Disable gofmt formatter" → edit formatters section, set languages.gofmt.enabled = false
skill-creator
by IgorWarzocha
Guide for creating effective opencode skills. Use for creating or updating skills that extend agent capabilities with specialized knowledge, workflows, or tool integrations. Examples: - user: "Create a skill for git workflows" → define SKILL.md with instructions and examples - user: "Add examples to my skill" → follow the user: "query" → action pattern - user: "Update skill description" → use literal block scalar and trigger contexts - user: "Structure a complex skill" → organize with scripts/ and references/ directories - user: "Validate my skill" → check structure, frontmatter, and discovery triggers
tdd-strict
by Svenja-dev
Erzwingt striktes Test-Driven Development mit Red-Green-Refactor Zyklus. Blockiert Code-Generierung ohne vorherige Tests. Dokumentiert 13 ungueltige Rationalisierungen. Aktivieren bei neuen Features, Bug Fixes, Refactoring.
skill-doc-generator
by Svenja-dev
Auto-generates standardized README documentation from SKILL.md files, validates consistency (frontmatter, descriptions, terminology), and creates usage examples. Use when documenting individual skills, generating docs for multiple skills in a directory, or validating skill quality standards.
strict-typescript-mode
by Svenja-dev
Enforces TypeScript best practices when writing code. Automatically enables strict typing for TypeScript projects, prevents any usage, and recommends generic constraints. Activate on TS/TSX files, new features, code reviews.
multi-agent-patterns
by Svenja-dev
Design multi-agent architectures for complex tasks. Use when single-agent context limits are exceeded, when tasks decompose naturally into subtasks, or when specializing agents improves quality.
dehallucination
by axiomantic
"Verify claims, references, and assertions are grounded in reality. Triggers: 'does this actually exist', 'is this real', 'did you hallucinate', 'verify these references', 'check if this is fabricated', 'reality check', 'ground truth'. Invoked as quality gate by roundtable feedback, Forge workflow, and after deep-research verification."
documenting-tools
by axiomantic
"Use when writing MCP tools, API endpoints, CLI commands, or any function that an LLM will invoke. Also use when LLMs misuse tools due to poor descriptions. Triggers: 'document this tool', 'write tool docs', 'MCP tool', 'tool description quality', 'model keeps calling this wrong', 'improve tool description'. For human-facing API docs, standard documentation practices apply instead."
async-await-patterns
by axiomantic
"Use when writing JavaScript or TypeScript code with asynchronous operations, fixing promise-related bugs, or converting callback/promise patterns to async/await. Triggers: 'promise chain', 'unhandled rejection', 'race condition in JS', 'callback hell', 'Promise.all', 'sequential vs parallel async', 'missing await'. Enforces async/await discipline over raw promises."
sharpening-prompts
by axiomantic
Use when reviewing LLM prompts, skill instructions, subagent prompts, or any text that will instruct an AI. Triggers: "review this prompt", "audit instructions", "sharpen prompt", "is this clear enough", "would an LLM understand this", "ambiguity check". Also invoked by instruction-engineering, reviewing-design-docs, and reviewing-impl-plans for instruction quality gates.
gathering-requirements
by axiomantic
"Use when eliciting or clarifying feature requirements, defining scope, identifying constraints, or capturing user needs. Triggers: 'what are the requirements', 'define the requirements', 'scope this feature', 'user stories', 'acceptance criteria', 'what should this do', 'what problem are we solving', 'what are the constraints'. Also invoked by implementing-features during DISCOVER stage and by the Forged workflow."
dbos-typescript
by dbos-inc
DBOS TypeScript SDK for building reliable, fault-tolerant applications with durable workflows. Use this skill when writing TypeScript code with DBOS, creating workflows and steps, using queues, using DBOSClient from external applications, or building applications that need to be resilient to failures.
