Task automation and scripting
python-concurrency-performance
by ahgraber
Use when designing or reviewing concurrent Python code — selecting between asyncio, threads, or multiprocessing; structuring cancellation and deadline propagation; bounding fan-out and backpressure. Also use when diagnosing race conditions, deadlocks, slow throughput, or thread/task leaks under load.

pomodoro
by jakedahn
Simple Pomodoro timer for focused work sessions with session tracking and productivity analytics. Use when users request focus timers, ask about productivity patterns, or want to track work sessions over time. Demonstrates the System Skill Pattern (CLI + SKILL.md + Database).
realistic-ugc-video
by dennisonbertram
Create realistic long-form AI talking head/UGC videos that don't look AI-generated. Use when user wants to make "realistic AI video", "UGC video", "talking head video", "AI spokesperson", "AI ad content", "video that looks real", "human-looking AI video". Orchestrates Nano Banana for base images and Kling AI for video generation with natural pacing.
bitrix24-agent
by vrtalex
Design, implement, debug, and harden integrations between AI agents and Bitrix24 REST API (webhooks, OAuth 2.0, scopes, events, batch, limits, and REST 3.0). Use when asked to connect AI assistants/agents to Bitrix24, automate CRM/tasks/chats, process Bitrix24 events, choose an auth model, or resolve Bitrix24 API errors and performance issues.
template-skill
by Interstellar-code
Replace with description of the skill and when Claude should use it.
webapp-testing
by Interstellar-code
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
a2a
by Tyler-R-Kendrick
Use when implementing the Agent-to-Agent (A2A) protocol for inter-agent communication, task delegation, and multi-agent collaboration. USE FOR: agent-to-agent communication, task delegation between agents, Agent Card publishing, multi-agent collaboration DO NOT USE FOR: tool integration (use mcp), agent payments (use ap2 or x402), agent definition (use adl)
mastergo
by jeasonstudio
Retrieve and analyze MasterGo design DSL data. Use when users provide MasterGo links (https://mastergo.com/file/xxx or /goto/xxx) to fetch design structure, component documentation, and DSL metadata.
select-svg-icon
by OriAshkenazi
Choose and validate SVG icons for pyRevit extension commands. Use when creating or updating a pyRevit pushbutton and you need an SVG-only icon workflow with automated acquisition from svgrepo.com first, manual fallback on svgfind.com, and vision-based semantic ranking before finalizing icon assets.
algorithm-design
by KentoShimizu
"Design algorithms by modeling constraints, enumerating candidate strategies, proving correctness, and selecting data structures with explicit tradeoffs. Use when implementation success depends on algorithm choice or decomposition under unclear constraints, from vague outcome requests to concrete directives; do not use for persistence schema or deployment topology decisions."
architecture-principles
by KentoShimizu
"Define architecture principles and review guardrails before choosing monolith, microservices, serverless, or event-driven options. Use when teams need explicit decision criteria; do not use to record final decisions."
algorithm-complexity-analysis
by KentoShimizu
"Analyze candidate algorithms for time/space complexity, scalability limits, and resource-budget fit (CPU, memory, I/O, concurrency). Use when feasibility depends on input growth or latency/memory constraints and quantitative bounds are required before implementation; do not use for persistence schema or deployment topology decisions."
design-principles
by KentoShimizu
"Define and align product design principles that teams can apply consistently across UX decisions. Use when product or UX direction is ambiguous and teams need explicit decision guardrails before detailed screens or components are produced; do not use for backend data-model or deployment pipeline decisions."
acceptance-criteria-design
by KentoShimizu
"Design executable acceptance criteria for approved requirements by converting goals/specs into binary pass/fail checks with observable outcomes. Use when implementation handoff, QA validation, or release decisions need testable criteria for stable REQ-/NFR- baselines; do not use for requirement discovery, prioritization, or sprint slicing."
chaos-engineering-basics
by KentoShimizu
"Design and execute controlled chaos experiments to validate resilience assumptions with explicit steady-state metrics, blast-radius limits, and abort rules. Use when reliability claims need evidence before wider rollout; do not use for active incident command or postmortem-only reporting."
code-review-performance
by KentoShimizu
"Run performance-focused code review when changes may affect latency, throughput, or CPU/memory/I/O efficiency on critical paths. Use for merge decisions requiring explicit performance-risk findings; do not use for broad non-performance review scope."
architecture-decision-records
by KentoShimizu
"Architecture Decision Record workflow for capturing technical decisions, alternatives, trade-offs, and revision triggers over time. Use when decisions materially affect system behavior, cost, or team workflow; do not use for trivial implementation choices."
architecture-tradeoff-analysis
by KentoShimizu
"Architecture trade-off analysis workflow for comparing options with explicit criteria, weighting, and sensitivity under uncertainty. Use when multiple viable architecture choices exist and rationale must be defensible; do not use after architecture direction is already fixed."
concurrency-patterns
by KentoShimizu
"Design and review concurrency strategy for shared state, coordination, and contention control. Use when parallel execution or async coordination introduces race/deadlock/liveness risk and explicit pattern selection is required; do not use for persistence schema or deployment topology decisions."
db-transaction-design
by KentoShimizu
"Transaction design workflow for boundary definition, isolation-level choice, and contention control under real workload behavior. Use when correctness depends on concurrent read/write semantics; do not use for schema-only tasks that do not affect transaction behavior."
db-backup-recovery
by KentoShimizu
"Database backup and recovery workflow for defining RPO/RTO-aligned retention, restore strategy, and disaster readiness. Use when data durability and recovery guarantees are in scope; do not use for query-only tuning tasks."
Advocacy Campaign Builder
by Eli-yu-first
"Build advocacy campaigns with messaging frameworks, stakeholder mapping, and action plans"
cellxgene-census
by ovachiever
"Query CZ CELLxGENE Census (61M+ cells). Filter by cell type/tissue/disease, retrieve expression data, integrate with scanpy/PyTorch, for population-scale single-cell analysis."
