Every Agent Skill we could find on GitHub, deduplicated by content. 79 404 files from 1 741 authors, of which 61 763 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.

Triggers on "Build", "Create", "Implement", "Document", or "Spec out". Version 3.5 adds Phase 2.5 Adversarial Review and renames internal verification to Spec Gate (structural completeness). Clarity Gate is now a separate standalone tool for epistemic quality.

Builds custom community nodes for n8n, the workflow automation platform. Activates when the user wants to create, scaffold, develop, test, lint, or publish an n8n node — including both declarative (REST API) and programmatic styles. Also triggers when the user mentions n8n nodes, n8n-cli, n8n-node, community nodes, node credentials, or anything related to extending n8n with custom integrations. Encodes all official best practices from n8n's documentation.
Builds, tests, validates, and manages n8n workflows programmatically using the @n8n/workflow-sdk. Activates when the user wants to create n8n workflows with code, convert between JSON and code, validate workflows, generate test/pin data, build AI agent workflows, or work with the n8n workflow SDK in any capacity. Also triggers on mentions of workflow-sdk, workflow builder, n8n workflow code, workflow JSON, workflow validation, code generation, or programmatic workflow creation.
