Invoke when the user asks to review, check, audit, or look over Qt6 QML code—or suggests doing so before committing. Runs deterministic linting (48+ rules), then deep-analysis agents scaled to the change size, covering bindings, layout, loaders, delegates, states, and performance. Optionally invokes system qmllint for type-level checks. Reports only high-confidence issues (>80/100) with structured mitigations. Read-only; never modifies code
Commit, push, branch, and manage version control with GitButler. Use for commits, selective dirty-file or hunk commits, branches, diffs, PRs, history edits, squashes, amends, undo, merge, fetching, pulling and syncing a branch with its remote, apply, unapply, and linked worktrees. For selected dirty files or hunks, inspect with `but diff`; use compact `but status` for commit order, branch/stack placement, or conflict overview; use `but status -fv` when file IDs or per-commit file details matter. Replaces git write commands, including fetch and pull. Applies in every checkout of the repository, even when a plain branch is checked out, including linked worktrees such as `.claude/worktrees/*`, and to git writes made while testing or cleaning up (stash, checkout -- <file>, restore, reset)
Guides the agent through migrating an existing Capacitor app project from CocoaPods to Swift Package Manager (SPM) for iOS dependency management. Covers prerequisite checks, inventorying installed Capacitor plugins, backing up customized iOS project files (Info.plist, AppDelegate.swift, Assets.xcassets, Base.lproj, App.entitlements, GoogleService-Info.plist, .xcconfig files, signing configuration), deleting the existing `ios/` folder, re-scaffolding with `npx cap add ios --packagemanager SPM`, restoring preserved files, re-syncing plugins, and verifying the build. Performs all migration steps manually — does not use the interactive `npx cap spm-migration-assistant` command. Do not use for Capacitor plugin projects, app projects already on SPM, app projects without an existing `ios/` folder, or non-Capacitor mobile frameworks
Connect AI agents (Claude Code, Claude Desktop, Cursor, VS Code, Cline, Codex) to Capacitor and Ionic tooling over Model Context Protocol.

External agent skill (MIT, github.com/DietrichGebert/ponytail). Forces the laziest solution that actually works: question whether the task needs to exist at all (YAGNI), reuse what is already in the codebase, reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Climb the ladder on every coding task — writing, adding, refactoring, fixing, reviewing, or designing code, and choosing libraries or dependencies. Supports intensity levels: lite, full (default), ultra. Never cut validation, error handling, security, or accessibility.
Guides consumption and understanding of Fusion backend services, APIs, and patterns for frontend/client developers, integrators, and architects. Shows reference implementations, explains architectural decisions, and clarifies contracts. USE FOR: understanding Fusion backend APIs, learning implementation patterns, exploring reference code, choosing the right integration point, and understanding authorization/validation/async patterns. DO NOT USE FOR: modifying backend services, creating new endpoints, database changes, or backend-specific development (use the fusion-services-developer agent or the target backend service repo instead).
SMS and MMS deep-dive reference. Covers SMS-specific error codes, message filtering troubleshooting ("Messages Being Filtered or Blocked?" diagnostic checklist), MMS media support (US/CA/AU only), and SMS pumping indicators. For sending SMS, use twilio-send-message instead. Use this skill only when debugging SMS delivery issues or needing SMS-specific details not in the consolidated send skill
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
