Specialized agent for integrating BarqNet backend with multiple client platforms (Desktop/Electron, iOS/Swift, Android/Kotlin). Handles API contracts, authentication flows, error handling, token management, cross-platform compatibility, and end-to-end data flow validation. Use when connecting backend APIs to client applications or debugging integration issues.

Compress, resize, and convert images for web/mobile. Handles PNG, JPG, WebP, SVG optimization. Use when user needs to optimize images for performance or convert formats.

File-to-agent mapping and manifest generation for composite monorepo audits. Provides dynamic discovery of all config agents, generates structured audit manifests with priority-ordered spawn instructions, and handles library vs consumer repo exclusions. Use when performing root-level composite audits that scan repository for all config files and coordinate parallel agent execution across 26+ config domains.

Lazy-load access to enterprise_bot codebase. Provides 12 nuclear protocol exports (cfg, CogTwin, auth, memory) and zipped source. Load SKILL.md instead of 60 files. Extract from src.zip on demand.

Use when the app is slow or when optimizing functions. Enforces profile-first methodology to prevent premature optimization.

Validate and manage D&D party configuration files including player names, character mappings, and DM information. Use when creating new party configs, troubleshooting speaker mapping issues, or verifying configuration before session processing.

Select appropriate models (haiku/sonnet/opus) and parallelize tasks. Use at the start of implementation to optimize model selection and identify parallelization opportunities.

This skill is used to design Android user flows and screen structures that match the existing app patterns and keep forms, lists and navigation clear.

Generate high-quality recommendation letters for graduate school (MS/PhD), academic positions (faculty/postdoc), and industry/government/NGO roles. Uses template-based approach with context-aware customization. USE WHEN user says 'write recommendation letter', 'letter of recommendation', 'reference letter', or requests academic/professional recommendations.

Update ClaudeKit Engineer projects to the latest version. Capabilities include update single projects (safe mode with test branches), batch update multiple projects, find all ClaudeKit projects in home directory, verify updates with automated checks, preserve user settings and code, create timestamped backups, handle git workflows (branch, commit, merge), and rollback if needed.
