debugging
Systematically diagnoses and resolves software bugs using various debugging techniques and tools. Trigger keywords: debug, bug, error, exception, crash, issue, troubleshoot, fix, stack trace.
code-migration
Strategies and patterns for safe code migrations and upgrades. Use when upgrading frameworks, migrating between technologies, handling deprecations, or planning incremental migrations. Triggers: migration, upgrade, deprecation, framework migration, version upgrade, legacy code, modernization, refactoring, feature flags, rollback.
analyze-m1-module-for-migration
Systematically analyze a Magento 1 module to determine its purpose, usage, and migration requirements for Magento 2. Use when you need to decide whether to migrate a M1 module, find alternatives, or skip it.
magento-controller-refactor
Scans and refactors deprecated Magento 2 controller patterns to modern HTTP verb interfaces. Use when modernizing controllers that extend deprecated Action base class or need PHP 8.3+ compatibility.
Git Investigation
This skill should be used when the user asks to "use git blame", "check git history", "find git commits", "use git log", "use git diff", "use git bisect", "trace code changes", "find who changed this code", or mentions using git commands for investigating code history and changes during root cause analysis.
nixos
Resolve NixOS issues using research and sequential thinking
root-cause-tracing
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior
emergency-ulimit-mitigation
Emergency steps to mitigate ulimit-related crashes by increasing file descriptor limits and restarting services.
recovering-from-bad-git-state
Techniques for diagnosing and recovering from corrupted git state, orphaned worktrees, and inconsistent branch references.
performance-optimization
Performance profiling, optimization techniques, and bottleneck identification. Use when addressing performance issues or optimizing systems.
debug-like-expert
Deep analysis debugging mode for complex issues. Activates methodical investigation protocol with evidence gathering, hypothesis testing, and rigorous verification. Use when standard troubleshooting fails or when issues require systematic root cause analysis.
refactor
>
tailscale
Troubleshoot Tailscale connectivity or access internal services via Tailscale hostnames.
skill-debugging-assistant
Debug, diagnose, and troubleshoot skill issues including trigger failures, parameter problems, prompt conflicts, and SKILL.md structural issues. Use when skills don't activate as expected, trigger incorrectly, produce unexpected behavior, conflict with system instructions, or fail packaging validation. Analyzes YAML frontmatter, descriptions, progressive disclosure, token budget, absolute statements, and reference file organization. For skill creators reviewing, validating, or fixing skill problems.
versioning-constitutions
Use when architectural patterns evolve, tech stack changes, or foundational rules need updates - creates new constitution version directory, migrates/organizes content into modular files, updates symlink, and documents changes
unix-macos-engineer
Expert Unix and macOS systems engineer for shell scripting, system administration, command-line tools, launchd, Homebrew, networking, and low-level system tasks. Use when the user asks about Unix commands, shell scripts, macOS system configuration, process management, or troubleshooting system issues.
ccpm-mcp-management
Discovers, manages, and troubleshoots MCP servers with three-tier classification (required: Linear/GitHub/Context7, optional: Jira/Confluence/Slack/BitBucket). Auto-activates when user asks "MCP server", "tools available", "Linear not working", "what tools do I have", or when plugin installation fails. Provides automatic server discovery, configuration validation, and health monitoring. Diagnoses connection issues (missing env vars, wrong config, network problems) with specific fix suggestions. Requires setup confirmation for optional PM integrations. Shows rate limit status and recommends optimizations when performance degrades.
