Audit a focused part of an existing codebase, reconstruct its behavior and past decisions, and record gaps in reasoning, coding practices, features, and technology choices. Use the findings to plan, test, implement, and verify improvements.
Map the impact of a proposed change using real dependencies and project documentation. Identify affected code, data, interfaces, tests, and release steps, then compare the implemented changes with the plan to expose gaps and unverified risks.
Check the full connection between a local agent API and a remote sandbox through a temporary tunnel. Run a task that needs no connected tools, verify its response, and restore the web app’s original API connection.
Create an SVG usage card from local Claude Code, Codex, Gemini CLI, and OpenCode logs. It summarizes token counts, equivalent API cost, consecutive activity days, and each agent's share for inclusion in a README or documentation.
Restructure repeated LLM API requests so shared instructions and reference material can be cached, meaning reused across calls. Track cached input, write and storage costs, and response times to assess whether the changes actually save money.
Investigate photos, videos, public accounts, and records using OSINT, research based on public information. Connect sparse clues, test competing explanations, and report evidence, confidence, and unresolved questions about locations, events, identities, or infrastructure relationships.
Review MCP configuration without running its servers. Identify npm, Python, and Docker references that may fetch different code later, classify their version settings, and recommend pinning versions or image contents that the team has reviewed.
Design and review Java database code using MyBatis and MyBatis-Spring. Covers mapping query results to objects, safe SQL parameters, transactions, pagination, batch writes, and investigating slow or unnecessarily repeated queries.
Route broad requests about project documentation to a suitable specialist skill. When requested, run a read-only audit of document roles, local links, architecture decision indexes, and evidence references, reporting failures and items needing review.
Turn Git changes into a clear commit message using Conventional Commits, a format that labels the change type and optional scope. Review repository history to match its conventions, and flag unrelated changes that should be split.
Plan and verify security controls for AI agents that read untrusted content and use tools. Review permissions, file boundaries, network destinations, and credentials, then test that rejected actions leave no unintended changes.
Build Bengali search and AI features with guidance on consistent character encoding, word splitting, digit conversion, and safe text display. Includes patterns for cleaning training data, storing text, and handling Bengali alongside English.
Plan database structure changes and existing data updates for production systems. Provides migration patterns for adding columns and indexes, switching applications in stages, and documenting recovery steps while accounting for downtime and database locks.
Design and review REST APIs, interfaces that exchange resources over HTTP, with consistent URLs, responses, and error handling. Covers pagination, authentication, request limits, and versioning to clarify how clients interact with an API.
Apply shared coding conventions to new modules, reviews, and refactoring. Guides descriptive naming, readable structure, updates that preserve existing data, and error handling, giving teams a consistent basis for checking code quality.
Extract reusable solutions and project conventions from completed Claude Code sessions and save them as learned skills. This deprecated version documents the older session-end workflow and explains how it differs from its successor.
Prepare web applications for production with Docker configurations, automated testing and deployment workflows, health checks, and rollback plans. Compare release strategies and review application, infrastructure, monitoring, security, and operational readiness before launch.
Turn Claude Code sessions into reusable working rules with evidence and confidence scores. Keep project-specific habits separate, share general patterns across projects, and group learned rules into skills, commands, or agents for repeated tasks.
Structure server-side applications with practical patterns for Node.js, Express, and Next.js API routes. Covers API design, database queries, caching, authentication, error handling, and background jobs, with examples that separate business rules from data access.
Record web application demos with Playwright, a browser automation tool. The workflow explores the interface, rehearses each step, and produces WebM videos with visible cursor movement, subtitles, and readable pacing.
Audit and improve a website’s search visibility by fixing technical issues, refining page titles and headings, adding structured data that describes content to search engines, and planning keywords and internal links.
Configure and troubleshoot Vite projects, covering environment variables, API proxies, plugins, and production builds. The skill also guides library packaging, dependency compatibility, and development server performance, with checks for exposed secrets and missing TypeScript validation.
Convert batches of design screenshots into Vue 3 page components, reusable interface sections, and initial routing code. Map visual elements to Vant, Element Plus, or Ant Design Vue, while using supplied image assets where appropriate.
Design a shared notification workflow across GitHub, Linear, local hooks, desktop alerts, and existing communication tools. Classify urgency and ownership, merge duplicate events, and decide which updates need immediate attention, a digest, or a log entry.
