Write, fix, or review HTTP contract tests in tests/stand/api/ — the deployed-stand suite against a real gateway, real Keycloak sessions and real backend images. Covers the operation catalogue, which persona session to take, requires_seed markers, the scratch-resource policy, the hand-written vs generated response models, status-code discipline (identity 404 vs analytics 403 outside a scope, 400 vs 415 vs 422) and the endpoint coverage gate. Use when adding or changing anything under tests/stand/api/, closing a coverage-gate gap, or turning a stand-scenarios claim into an API case. For browser journeys use stand-ui-test. Seeded-bronze → served-metric specs are the data-path suite in tests/datapath/ (metric-test).

Sirv dynamic imaging URL API for on-the-fly image transformation.

Covers 100+ URL parameters for scaling, cropping, effects, text, watermarks, frames, and optimization.

Sirv REST API integration for image and file management. Use when working with Sirv CDN, uploading/downloading files to Sirv, managing image metadata, searching files, creating 360 spins, converting videos, or any Sirv API operations. Covers authentication, file operations, metadata, search queries, async jobs, and account management.

Guide for implementing smooth, native-feeling animations using React's View Transition API (`<ViewTransition>` component, `addTransitionType`, and CSS view transition pseudo-elements). Use this skill whenever the user wants to add page transitions, animate route changes, create shared element animations, animate enter/exit of components, animate list reorder, implement directional (forward/back) navigation animations, or integrate view transitions in Next.js. Also use when the user mentions view transitions, `startViewTransition`, `ViewTransition`, transition types, or asks about animating between UI states in React without third-party animation libraries.

Checks which private files (.env, keys, secrets) Claude Code and its subagents reached in this project, whether a value came into an agent's context, and which key to change, by running the open source agentwhy CLI over the session records Claude Code already keeps on disk. Use when the user asks whether the agent or a subagent read their .env or other secrets, which private files a session touched, whether a key leaked into the conversation, or which key to rotate. Runs locally and never prints a secret value.

Active runtime recovery for coding agents: when something breaks mid-task, diagnose the root cause, write a fix, VERIFY by re-running the broken thing, then file a `HEAL-` entry to `.learnings/HEALS.md` with proof. Use whenever a command, test, build, or lint fails or exits non-zero; on missing tooling, dependency/lockfile mismatch, wrong runtime version, venv or permission errors, port conflicts, dirty git state, or a missing `.env`; when the agent needs a helper or one-off script that doesn't exist yet; when an external API, tool, or MCP errors or rate-limits; or when a test flakes. Search `HEALS.md` by `Pattern-Key` first — most heals are recurrences, so increment `Recurrence-Count` instead of duplicating. Verify is mandatory: mark `pending-verify` honestly if sandboxed, `abandoned` if the fix can't be made to work. Pairs with `self-improvement` (which promotes recurring heals to durable memory) but owns the verify-before-persist discipline self-improvement doesn't.

Skill de isolamento de workspace via git worktree, com deteccao de isolamento existente, preferencia por ferramenta nativa (`EnterWorktree`/`ExitWorktree` ou dispatcher do kit `/worktree`) antes de cair para `git worktree add` cru, e baseline de testes obrigatoria antes de liberar a task para trabalho. Eleva o comando `/worktree` do kit para protocolo completo quando a situacao exige as garantias extras (evitar aninhamento de worktree, confirmar workspace limpo antes de comecar). Trigger em: "worktree", "isolar workspace", "trabalhar isolado", "workspace isolado", "criar worktree", "ja estou num worktree", "aninhar worktree", "worktree dentro de worktree", "baseline de testes", "verificar baseline limpa", "detectar isolamento", "git worktree add", "ferramenta nativa de worktree", "EnterWorktree", "plano de implementacao isolado", "trabalho paralelo sem afetar o branch atual".

Use when writing or reviewing C# code in this repo that builds an interactive Deepgram Voice Agent over WebSocket. Covers `ClientFactory.CreateAgentWebSocketClient()`, `SettingsSchema`, event subscriptions, microphone audio streaming, injected user messages, and function-call-related message types.

MUST be used for Vue.js tasks. Strongly recommends Composition API with `<script setup>` and TypeScript as the standard approach. Covers Vue 3, SSR, Volar, vue-tsc. Load for any Vue, .vue files, Vue Router, Pinia, or Vite with Vue work. ALWAYS use Composition API unless the project explicitly requires Options API.

Searches, installs, updates, and lists skills from the Antigravity Skill Vault. Use when choosing or managing workspace or global skills through the npm CLI.

Start and control Minutes Coach, the separate real-time copilot HUD, with an explicit meeting goal. Use only for explicit Coach or HUD lifecycle requests such as "start Minutes Coach", "open the Coach HUD", "pause Minutes Coach", "resume Minutes Coach", "Minutes Coach status", or "stop Minutes Coach". Do not use for requests that explicitly ask the current terminal agent to watch or strategize; those belong to minutes-live-sidekick. An ambiguous request such as "coach me live" requires one short surface clarification and must not automatically start Coach.

Manage old recordings — find large files, archive old meetings, delete processed originals. Use when the user says "clean up recordings", "how much space are meetings using", "delete old recordings", "archive meetings", "manage meeting storage", or asks about disk space from minutes.

Localizes keywords, meta tags, numbers, dates, currencies, and quote styles per locale. Flags machine-translation artifacts for review. Run BEFORE blog-localize: this handles language conversion; localize handles cultural adaptation after translation completes. Use when user says "translate blog", "blog translate", "uebersetzen", "traduire", "traducir", "translate post", "blog auf Deutsch", "blog en espanol".
