Debugging
Find and fix bugs, error analysis
rust
by cosmix
Rust language expertise for writing safe, performant, production-quality Rust code. Primary language for the Loom project. Use for Rust development, ownership patterns, error handling, async/await, cargo management, CLI tools, and serialization. Triggers: rust, cargo, rustc, ownership, borrowing, lifetime, trait, impl, struct, enum, Result, Option, async, await, tokio, serde, clap, thiserror, anyhow, Arc, Mutex, RwLock, RefCell, Box, Rc, Vec, HashMap, HashSet, String, derive, macro.
before-after
by cosmix
Generates before/after verification pairs for loom plans. Proves a stage actually changed system behavior by capturing state before and after implementation. Use for delta-proof verification — proving new commands, endpoints, modules, or bug fixes work by comparing system state.

Supports Gemini CLI for deep analysis. Triggers on "skill tuning", "tune skill", "skill diagnosis", "optimize skill", "skill debug".
mssql
by sanjay3290
"Execute read-only SQL queries against multiple Microsoft SQL Server databases. Use when: (1) querying MSSQL/SQL Server databases, (2) exploring database schemas/tables, (3) running SELECT queries for data analysis, (4) checking database contents. Supports multiple database connections with descriptions for intelligent auto-selection. Blocks all write operations (INSERT, UPDATE, DELETE, DROP, etc.) for safety."

Test Quality Inspector
by bobmatnyc
Systematically inspect unit and E2E tests to verify they test the right behavior, provide meaningful coverage, and catch real regressions
pm-bug-reporting
by bobmatnyc
Bug reporting protocol for PM and agents to file GitHub issues
Root Cause Tracing
by bobmatnyc
Systematically trace bugs backward through call stack to find original trigger
Testing Anti-Patterns
by bobmatnyc
Never test mock behavior. Never add test-only methods to production classes. Understand dependencies before mocking.
testing-anti-patterns
by sammcj
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behaviour, production pollution with test-only methods, and mocking without understanding dependencies
django-celery-expert
by vintasoftware
Expert Django and Celery guidance for asynchronous task processing. Use when designing background tasks, configuring workers, handling retries and errors, optimizing task performance, implementing periodic tasks, or setting up production monitoring. Follows Celery best practices with Django integration patterns.
