Follow consistent project structure, version control practices, environment configuration, code review processes, and development conventions across the entire application. Use this skill when organizing project files and directories, when writing commit messages or creating pull requests, when managing environment variables and configuration, when participating in code reviews, when defining testing requirements, when using feature flags, when maintaining changelogs, when documenting setup instructions, or when establishing consistent development practices across the team.

Process large documents (200+ pages) with structure preservation, intelligent parsing, and memory-efficient handling. Use when working with complex formatted documents, multi-level hierarchies, or when you need to extract structured data from large files like PDFs, DOCX, or text files.

Analyze training patterns, performance, and physiological data using advanced computational models.AUTO-ACTIVATES when user asks about:- Training status/progress ("How am I doing?", "How's my training?")- Load/overtraining ("Am I overtraining?", "Is my load too high?")- Performance questions ("Why did I fade?", "What's limiting me?")- Specific run analysis ("Why was my HR high?", "What happened yesterday?")- Race readiness ("Am I ready?", "Will I make my goal?")- Physiological zones ("What are my zones?", "What's my threshold?")- Recovery/freshness ("Should I run today?", "Am I recovered?")- Patterns/causation ("What's causing...", "What predicts my best runs?")PROACTIVELY WARNS when detecting:- ACWR > 1.3 (load spike)- TSB < -25 (fatigue accumulation)- Correlation shifts (relationship changes)- Form breakpoints earlier than usual- Recovery decline between intervals

[TODO: Complete and informative explanation of what the skill does and when to use it. Include WHEN to use this skill - specific scenarios, file types, or tasks that trigger it.]

Environment/config conventions (env vars, defaults, validation, CI/local differences). Use when adding config or diagnosing env-related failures.

Specification-Test-Driven Development workflow - write spec first, then tests, then implementation - uses specification and test-driven-development skills

Manage Model Context Protocol (MCP) servers - discover, analyze, and execute tools/prompts/resources from configured MCP servers. Use when working with MCP integrations, need to discover available MCP capabilities, filter MCP tools for specific tasks, execute MCP tools programmatically, access MCP prompts/resources, or implement MCP client functionality. Supports intelligent tool selection, multi-server management, and context-efficient capability discovery.

Master algorithm design, common patterns, optimization techniques, and problem-solving strategies. Learn to solve any computational challenge efficiently.

Proactively use this skill when starting any code writing or refactoring task and must uphold SOLID, DRY, KISS, YAGNI, and SSOT principles.
