Interactive conversation to resolve [NEEDS CLARIFICATION] markers using /speckit.clarify command. Claude asks questions about missing features, UX/UI details, behavior, and priorities. Updates specs in .specify/memory/ with answers to create complete, unambiguous documentation. This is Step 5 of 6 in the reverse engineering process.
Audit and improve SwiftUI runtime performance from code review and architecture. Use for requests to diagnose slow rendering, janky scrolling, high CPU/memory usage, excessive view updates, or layout thrash in SwiftUI apps, and to provide guidance for user-run Instruments profiling when code review alone is insufficient.
Apply Android/Jetpack Compose design principles following Material Design 3 when building any Android UI component. Only execute this when the current project is an Android project and involves UI-related work. Use this skill for Compose layouts, Material components, or Android app development. Ensures Material You compliance with Dynamic Color, expressive theming, 4dp grid spacing, Roboto typography with Type Scale, and native Android patterns. Prevents common anti-patterns like hardcoded colors, Dark Mode neglect, and touch target violations.
Secure provisioning for TizenRT/ARTIK IoT devices. Coordinates certificate installation, key management, and network onboarding.
Local storage, data sync, and conflict resolution for offline-capable apps.
Debug running App Platform applications by accessing containers, analyzing logs, running diagnostics, and applying fixes. Use when apps fail to deploy, crash at runtime, have connectivity issues, or need performance diagnosis.
This skill enables control of Android devices via ADB and the accessibility API. Use this skill when users want to automate Android phone tasks, control apps remotely, tap buttons, type text, navigate UI, or perform any action on a connected Android device. Requires ADB and a connected device with USB debugging enabled.
Package entire code repositories into single AI-friendly files using Repomix. Capabilities include pack codebases with customizable include/exclude patterns, generate multiple output formats (XML, Markdown, plain text), preserve file structure and context, optimize for AI consumption with token counting, filter by file types and directories, add custom headers and summaries. Use when packaging codebases for AI analysis, creating repository snapshots for LLM context, analyzing third-party libraries, preparing for security audits, generating documentation context, or evaluating unfamiliar codebases.
Use this skill when managing packages, external dependencies, binaries, or CLI tools in a chezmoi dotfiles repository. Handles adding/updating/removing packages in .chezmoidata/packages.yaml, creating .chezmoiexternals/ organized files, pinning versions with Renovate automation, and selecting the correct package ecosystem (Homebrew, mise, Python, Docker, chezmoi externals).
Manage and analyze releases across projects, review deployment processes, and track Git branch deployments
Generate and maintain CHANGELOG.md files following Keep a Changelog format. Use when creating changelogs, documenting releases, or tracking project changes.
Auto-detects project language and framework from package.json, pyproject.toml, Cargo.toml, go.mod, and other configuration files with comprehensive pattern matching based on 17,253+ production code examples.
Enhanced changelog generation with semantic versioning, auto-categorization, and release notes. Parses conventional commits, determines version bump (MAJOR.MINOR.PATCH), categorizes changes by type, generates CHANGELOG.md updates, and creates GitHub release notes. Use before releases or on PR merge to automate version management.
