Claude Skills

Initialize and manage specification directories with auto-incrementing IDs. Use when creating new specs, checking spec status, tracking user decisions, or managing the docs/specs/ directory structure. Maintains README.md in each spec to record decisions (e.g., PRD skipped), context, and progress. Orchestrates the specification workflow across PRD, SDD, and PLAN phases.

Create and validate product requirements documents (PRD). Use when writing requirements, defining user stories, specifying acceptance criteria, analyzing user needs, or working on product-requirements.md files in docs/specs/. Includes validation checklist, iterative cycle pattern, and multi-angle review process.

Document business rules, technical patterns, and service interfaces discovered during analysis or implementation. Use when you find reusable patterns, external integrations, domain-specific rules, or API contracts. Always check existing documentation before creating new files. Handles deduplication and proper categorization.

Discover patterns, rules, and interfaces through iterative analysis cycles. Use when analyzing business rules, technical patterns, security, performance, integration points, or domain-specific areas. Includes cycle pattern for discovery to documentation to review workflow.

Apply scientific debugging methodology through conversational investigation. Use when investigating bugs, forming hypotheses, tracing error causes, performing root cause analysis, or systematically diagnosing issues. Includes progressive disclosure patterns, observable actions principle, and user-controlled dialogue flow.

Validate implementation against specifications (PRD/SDD/PLAN). Use when verifying specification compliance, checking interface contracts, validating architecture decisions, detecting deviations, or ensuring implementations match documented requirements. Provides structured compliance reporting.

Create and validate implementation plans (PLAN). Use when planning implementation phases, defining tasks, sequencing work, analyzing dependencies, or working on implementation-plan.md files in docs/specs/. Includes TDD phase structure and specification compliance gates.

Create and validate solution design documents (SDD). Use when designing architecture, defining interfaces, documenting technical decisions, analyzing system components, or working on solution-design.md files in docs/specs/. Includes validation checklist, consistency verification, and overlap detection.

Coordinate multi-agent code review with specialized perspectives. Use when conducting code reviews, analyzing PRs, evaluating staged changes, or reviewing specific files. Handles security, performance, quality, and test coverage analysis with confidence scoring and actionable recommendations.

Analyzes user requirements and recommends the best Taiwan payment gateway. Provides comparison between NewebPay, ECPay, and PAYUNi based on specific needs. Use when choosing a payment solution or comparing 金流服務.

Implements NewebPay transaction query functionality using QueryTradeInfo API. Use when building order status checking, transaction verification, or payment confirmation features for 藍新金流.

Provides PAYUNi (統一金流) integration guide including payment gateway setup and API configuration. Use when integrating PAYUNi payment services or unified payment solutions.

Provides NewebPay integration overview and guides users to the appropriate skill. Use when starting NewebPay integration, setting up environment, or needing general guidance about 藍新金流.

Provides ECPay (綠界科技) integration guide including payment setup and electronic invoice integration. Use when integrating ECPay payment gateway or e-invoice features.

Implements NewebPay refund functionality for credit cards and e-wallets. Use when building refund processing, transaction cancellation, or return payment features for 藍新金流.

Implements NewebPay MPG checkout integration including AES256 encryption, form submission, and payment callback handling. Use when integrating payment gateway, creating checkout flows, or building 藍新金流 payment pages.

Create commit messages following Sentry conventions. Use when committing code changes, writing commit messages, or formatting git history. Follows conventional commits with Sentry-specific issue references.

This skill should be used when the user asks to "create AGENTS.md", "update AGENTS.md", "maintain agent docs", "set up CLAUDE.md", or needs to keep agent instructions concise. Guides discovery of local skills and enforces minimal documentation style.

Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
