Use when you need to execute R3 (Prototype Generation) in the product requirement Spec process of sdlc-dev, generate requirements/prototype.md based on requirements/prd.md (including task flow + page structure + ASCII wireframe + AC mapping + walkthrough script), and avoid proceeding with generation without context/PRD, using Open Questions instead of verification checklists, or using non-ASCII formats that make the prototype untraceable and unreviewable.
Linux system troubleshooting workflow for diagnosing and resolving system issues, performance problems, and service failures.
This skill should be used when the user asks to "validate a finding", "check if a vulnerability is real", "triage a security finding", "confirm a vulnerability", "determine if a finding is a true positive or false positive", or provides a security finding for review. It validates security vulnerability findings by tracing data flows, verifying exploit conditions, analyzing security controls, and optionally testing attack vectors against a live application.
Navigates C3 architecture docs and explores corresponding code to answer architecture questions. Use when the user asks: - "where is X", "how does X work", "explain X", "show me the architecture" - "find component", "what handles X", "diagram of X", "visualize X" - "describe X", "list components", "trace X", "flow of X" - References C3 IDs (c3-0, c3-1, adr-*) <example> Context: Project with .c3/ directory user: "explain what c3-101 does and how it connects to other components" assistant: "Using c3-query to navigate the architecture docs." </example> <example> Context: Project with .c3/ directory user: "show me a diagram of the C3 architecture" assistant: "Using c3-query to generate an architecture overview." </example> DO NOT use for changes (route to c3-change). DO NOT use for pattern artifact management — listing, creating, updating refs (route to c3-ref). Requires .c3/ to exist.
PostgreSQL database optimization workflow for query tuning, indexing strategies, performance analysis, and production database management.
Builds elaborate multi-component claude.ai HTML artifacts using React 18, TypeScript, Vite, Tailwind CSS, and shadcn/ui bundled into single-file deliverables. Use when asked to "create complex artifact", "build React artifact with routing", "use shadcn/ui components", "create stateful web app artifact", or "build multi-component frontend". Provides initialization scripts, development workflow, and Parcel bundling to create sophisticated single-HTML artifacts with state management and modern components. Works with React/TypeScript stack for claude.ai artifacts requiring complexity beyond simple HTML/JSX.
Parses OpenTelemetry-formatted logs to reconstruct execution traces, extract errors with call chains, and provide AI-powered root cause analysis. Use when investigating errors, checking logs, debugging issues, viewing traces, or analyzing execution flow. Triggers on "check the logs", "analyze errors", "what's failing", "debug this issue", "show me the traces", or "investigate the error".
Comprehensive Excel spreadsheet creation, editing, and analysis using openpyxl and xlwings supporting formulas, formatting, data analysis, charts, and financial model color coding. Use when asked to "create a spreadsheet", "edit this Excel file", "analyze spreadsheet data", "preserve Excel formulas", "create financial model", or "recalculate formulas". Implements industry-standard color conventions (blue=inputs, black=formulas, green=internal links, red=external links, yellow=key assumptions) and zero formula error requirements. Works with .xlsx, .xlsm, .csv, .tsv files for professional spreadsheet workflows.

Helps users discover and install agent skills from the open skills ecosystem (skills.sh). Use when users ask 'how do I do X', 'find a skill for X', 'is there a skill that can...', want to search for tools/templates/workflows, or express interest in extending agent capabilities.
DSPy optimization workflows — teleprompters, metrics, evaluation, and compilation strategies. Use when optimizing DSPy programs with BootstrapFewShot, MIPROv2, or custom metrics.
This skill should be used when users want to migrate from .env files to fnox with 1Password (or another secret provider). It covers installing fnox, creating 1Password items, configuring fnox.toml, and integrating with mise. Use when users mention ".env migration", "fnox setup", "1password secrets", or want to improve their secret management workflow.
