Debugging
Find and fix bugs, error analysis
warden
by getsentry
Run Warden to analyze code changes before committing. Use when asked to "run warden", "check my changes", "review before commit", "warden config", "warden.toml", "create a warden skill", "add trigger", or any Warden-related local development task.
bug-hunt-swarm
by Dimillian
"Parallel read-only multi-agent root-cause investigation for bugs, regressions, crashes, flaky behavior, or unexplained failures. Use when the user asks to investigate a bug, find the root cause, trace a regression, understand why something broke, or wants a ranked diagnosis with the fastest proof path without making code edits."
optimizing-query-text
by AltimateAI
Optimizes Snowflake SQL query performance from provided query text. Use when optimizing Snowflake SQL for: (1) User provides or pastes a SQL query and asks to optimize, tune, or improve it (2) Task mentions "slow query", "make faster", "improve performance", "optimize SQL", or "query tuning" (3) Reviewing SQL for performance anti-patterns (function on filter column, implicit joins, etc.) (4) User asks why a query is slow or how to speed it up
Testing Patterns
by Dicklesworthstone
Common testing patterns and practices. This skill is designed to be included in composite skills via the 'includes' feature.
tdd
by udecode
Use when implementing complex logic that needs test coverage - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first; NOT for UI components, simple CRUD, or straightforward code
changelog
by udecode
Use when updating CHANGELOG.md. Enforces consistent formatting with bolded item names, dash separators, and specific section ordering.
learn
by udecode
Continuous learning system that extracts reusable knowledge from work sessions. Triggers: (1) /learn command to review session learnings, (2) "save this as a skill" or "extract a skill from this", (3) "what did we learn?", (4) After any task involving non-obvious debugging, workarounds, or trial-and-error discovery. Creates new Claude Code skills when valuable, reusable knowledge is identified.
trace
by udecode
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
debug
by udecode
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions
download-file
by accomplish-ai
'Download files in Chrome on Windows and macOS. Handles triggering downloads, detecting and resolving popups, verifying completion, and locating files.'
git-commit
by accomplish-ai
Create well-structured git commits with conventional commit messages, proper staging, and commit best practices.
code-simplifier
by caarlos0
Simplify and refine code for clarity, consistency, and maintainability while preserving functionality. Use when asked to "simplify", "clean up", or "refactor" code, after writing complex code that could benefit from simplification, or when code has grown hard to follow.
accessibility-auditor
by TerminalSkills
Audit web pages and components for WCAG 2.2 accessibility compliance. Use when a user asks to check accessibility, find a11y issues, audit for WCAG compliance, fix screen reader problems, check color contrast, ensure keyboard navigation works, or prepare for accessibility regulations like the European Accessibility Act or ADA.
alert-optimizer
by TerminalSkills
Restructure and optimize alert rules for monitoring platforms (Sentry, PagerDuty, Datadog, OpsGenie). Use when someone asks to "reduce alert noise", "fix alert fatigue", "create alert rules", "set up escalation policies", "tune alerting thresholds", or "create on-call runbooks". Generates platform-specific alert configurations and tiered escalation policies.
llvm-learning
by gmh5225
Comprehensive learning resources and tutorials for LLVM, Clang, and compiler development. Use this skill when helping users learn LLVM internals, find educational resources, or understand compiler concepts.
godot-genre-survival
by thedivergentai
"Expert blueprint for survival games (Minecraft, Don't Starve, The Forest, Rust) covering needs systems, resource gathering, crafting recipes, base building, and progression balancing. Use when building open-world survival, crafting-focused, or resource management games. Keywords survival, needs system, crafting, inventory, hunger, resource gathering, base building."
ask-claude
by ryoppippi
Consult Claude Code for a second opinion on implementation plans, code reviews, or problem-solving. Use when you want an independent perspective from a different AI agent before making significant decisions.
setup-check
by ReinaMacCredy
Verify Maestro plugin prerequisites — Agent Teams flag, jq, trace MCP, PSM tools, directories, and hooks.
review
by ReinaMacCredy
Code review with auto-fix — plan-vs-implementation comparison or structured git-diff review. Automatically fixes issues found during review.
doctor
by ReinaMacCredy
Diagnose and fix Maestro installation issues
symfony:test-doubles-mocking
by MakFly
Drive Symfony delivery with deterministic tests and strong regression protection. Use for test doubles mocking tasks.
order-lifecycle
by JoelLewis
"Order lifecycle management: order states, FIX protocol basics, order types, time-in-force, cancel/replace workflows, order validation, and state machine design for trading systems."
sentry-ios-swift-setup
by getsentry
Setup Sentry in iOS/Swift apps. Use when asked to add Sentry to iOS, install sentry-cocoa SDK, or configure error monitoring, tracing, session replay, logging, or profiling for iOS applications using Swift and SwiftUI.
effect-best-practices
by forcedotcom
Enforces Effect-TS patterns for services, errors, layers, and atoms. Use when writing code with Effect.Service, Schema.TaggedError, Layer composition, or effect-atom React components.
