uv-package-manager
Master the uv package manager for fast Python dependency management, virtual environments, and modern Python project workflows. Use when setting up Python projects, managing dependencies, or optimizing Python development workflows with uv.
ultrathink-detective
A specialized Claude skill that enforces AST-based code analysis using claudemem v0.3.0, prohibiting grep/find/glob. Provides structured workflows for architecture mapping, dependency tracing, and impact analysis through six distinct analysis dimensions with clear command patterns.
react-patterns
Provides concrete patterns for React 19 features including React Compiler optimization, Server Actions, and new hooks. Offers clear guidance on when to use Actions vs TanStack Query mutations, with practical code examples for form handling, optimistic updates, and component composition.
api-contract-design
Provides concrete patterns for designing REST and GraphQL APIs, including resource modeling, HTTP semantics, error formats, pagination, and versioning strategies. Includes specific examples for OpenAPI specifications and authentication flows. Focuses on contract-first design and consistency across endpoints.
claude-cli
Provides comprehensive control over Claude's CLI for interactive sessions, script automation, and MCP server management. Offers fine-grained tool permissions, session persistence, JSON output for parsing, and project-specific MCP configuration.
work-summary
This skill analyzes git repositories to generate work summaries for performance reviews. It extracts commit history, code changes, and contribution patterns over a user-defined time range, producing structured reports in markdown, text, or JSON formats. It helps developers quantify their work output.
refactoring-patterns
Provides concrete refactoring patterns and safety rules for improving code structure. Includes specific examples like Extract Method and Replace Loop with Pipeline, plus anti-patterns to avoid. Emphasizes test-first approach and small, incremental changes.
wheels-migration-generator
Generates database-agnostic migration code for CFWheels applications with transaction handling, error recovery, and cross-database compatibility. Provides concrete examples for creating tables, altering schemas, managing indexes, and handling foreign keys while preventing database-specific SQL anti-patterns.
condition-based-waiting
Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses
implementing-jsc-classes-zig
Creates JavaScript classes using Bun's Zig bindings generator (.classes.ts). Use when implementing new JS APIs in Zig with JSC integration.
domain-driven-design
Provides tactical and strategic Domain-Driven Design patterns including entities, value objects, aggregates, and bounded contexts. Includes concrete examples, decision tables, and visual diagrams for modeling business domains with clear boundaries and consistency strategies.
skill-creator
Create or update AgentSkills. Use when designing, structuring, or packaging skills with scripts, references, and assets.
fix
Use when you have lint errors, formatting issues, or before committing code to ensure it passes CI.

submit-work
Submit completed work for a task on OpenAnt. Submission = text description + files. IMPORTANT — before submitting, always check if your work produced any files and upload them first. Use when the agent has finished work and wants to deliver results, submit a solution, turn in deliverables, upload files, or send proof of completion. Covers "submit work", "deliver results", "I'm done", "here's my work", "submit solution", "upload and submit", "attach proof", "deliver file", "send deliverable".
activitypub-dev-cycle
This Skill provides a reference for development workflows in the WordPress ActivityPub plugin. It covers environment setup with wp-env, running PHP and E2E tests, code linting for PHP/JS/CSS, building assets, and automated pre-commit hooks. It includes specific commands for common tasks like debugging tests and generating coverage reports.
handling-rust-errors
This skill provides HASH-specific patterns for using the error-stack crate in Rust projects. It enforces consistent error handling, distinguishes between compiler and infrastructure code, and includes practical examples for defining, propagating, and documenting errors. The skill is tightly integrated with HASH's development workflow.
claude-reflect
A two-stage system that captures user corrections during Claude sessions and queues them for review. Users run /reflect to apply learnings to CLAUDE.md files. It detects correction patterns like 'no, use X' and 'actually...' to help Claude remember preferences across sessions.
react-hook-form-zod
Build type-safe validated forms using React Hook Form v7 and Zod v4. Single schema works on client and server with full TypeScript inference via z.infer. Use when building forms, multi-step wizards, or fixing uncontrolled warnings, resolver errors, useFieldArray issues, performance problems with large forms.
financial-modeling
A structured workflow for financial modeling that guides users through six phases: scoping, architecture, assumptions, build, validation, and documentation. It enforces best practices like input separation, no hardcoding, and mandatory sensitivity analysis while dispatching to a specialized financial-modeler agent.
qa-resilience
Provides concrete patterns for testing system resilience including circuit breakers, retry strategies, timeout policies, and chaos experiments. Includes decision trees, library recommendations, and anti-patterns to avoid. Focuses on validating degraded modes and production guardrails.
simpy
Process-based discrete-event simulation framework in Python. Use this skill when building simulations of systems with processes, queues, resources, and time-based events such as manufacturing systems, service operations, network traffic, logistics, or any system where entities interact with shared resources over time.
exploratory-testing-advanced
Comprehensive exploratory testing framework with excellent structure, practical heuristics, and thoughtful agent integration for systematic quality investigation.
bioservices
Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.
