Use the Volcengine RDS MySQL MCP Server to help users manage instances, operate databases, manage accounts, and perform maintenance tasks related to RDS MySQL. Call the uv run ./scripts/call_rds_mysql.py script directly to get real-time results.
Use when building a narrated, voiceover-synced motion-graphics explainer or B-roll film in Remotion — paper-texture collage, cut-out subjects with an offset red marker stroke, code-drawn charts, newspapers, documents and typewriter reveals. Horizontal 1920x1080 by default, vertical 1080x1920 for TikTok, Reels and Shorts on request. Triggers on "make a vox style video", "vox editorial video", "b-roll sequence", "Remotion explainer", "documentary motion graphics about X", "turn this script into a video", "make a TikTok explainer". Not for hard-sell product ads (use fastcut-ad).

Use when writing tests for vvvv packages, setting up test infrastructure, creating test patches, running automated compilation checks, or integrating vvvv tests into CI/CD.
Webflow Enterprise API endpoints for workspace management, audit logs, site activity, 301 redirects, robots.txt, and well-known files. Use when working with Enterprise-only Webflow API endpoints that require an Enterprise workspace.
Reviews Workers and Cloudflare Developer Platform code for type correctness, API usage, and configuration validity. Load when reviewing TypeScript/JavaScript using Workers APIs, wrangler.jsonc/toml config, or Cloudflare bindings (KV, R2, D1, Durable Objects, Queues, Vectorize, AI, Hyperdrive).
Shared lifecycle contract for manual/auto control-flow plus optional ai-proxy overlay recognition in workflow skills: auto and overlay always revert to manual on completion or interruption; re-entry needs an explicit trigger; implicit continuation never re-activates them; batch orchestrators pass Stage-exit policy explicitly. Overlay maps to auto carrier + policy; charter stays in ai-proxy-discipline. Hosts that omit ai-proxy triggers ignore overlay. Referenced via frontmatter dependencies. Triggers — 「模式生命周期」「切换自动模式」「切换 ai-proxy」 / workflow mode lifecycle. Do NOT use as the proxy charter or as a third control-flow enum.
Unified test-fix pipeline combining test generation (session, context, analysis, task gen) with iterative test-cycle execution (adaptive strategy, progressive testing, CLI fallback). Triggers on "workflow-test-fix", "test fix workflow".
Expert guidance for using JJ (Jujutsu) version control system. Use when working with JJ, whatever the subject. Operations, revsets, templates, debugging change evolution, etc. Covers JJ commands, template system, evolog, operations log, and interoperability with git remotes.
Read and use comments attached to the current PostHog task, its artifacts, and any canvas through the PostHog MCP exec dispatcher. Use when the user mentions task comments, artifact or canvas comments, annotations, selected-text feedback, replies, unresolved comments, or asks an agent to inspect or act on feedback left in PostHog Desktop. Covers exec discovery and calls, target filtering, pagination, full-thread retrieval, anchor/version context, task-scoped access, and standalone canvas comments that have no task
worma OpenAPI code generation and configuration. Use this skill whenever the user mentions worma config, API code generation, OpenAPI/Swagger integration, worma CLI, or migration from @alova/wormhole, axios, or ky. Trigger for questions about worma.config, npx worma init/gen, generating API code from OpenAPI specs, or switching from @alova/wormhole, axios, or ky to worma.
WordPress admin UI review and development guidance. Use when reviewing admin pages, settings screens, menu pages, notices, list tables, metabox-like interfaces, screen options, capability checks, admin scripts or styles, or when user mentions "admin UI", "settings page", "wp-admin", "admin screen", "options page", "list table", "admin menu", "admin notice", "screen options", or "dashboard page".

Use when the user wants to improve accessibility, make a component accessible, fix WCAG violations, add keyboard support, or ensure screen reader compatibility.
Remediate GitHub Actions action findings identified by the action-audit skill. Applies the appropriate fix per action type — `@main` ref for internal `bitwarden/` actions, full SHA with inline version comment for external actions, or full replacement — across selected repos and creates draft PRs. Run the action-audit skill first to identify findings before using this skill. <example> User: Go ahead and fix the unpinned actions from the audit Action: Trigger action-remediate to apply fixes and create PRs </example> <example> User: Replace tj-actions/changed-files with the safe version across those repos Action: Trigger action-remediate to swap the action and create PRs </example>
Triages open PR feedback, verifying each review thread, review summary, and comment against the code, then carrying out each item's recommended option, declines and clarifying questions included, and pausing only on exclusions. Use when the user says "address the PR comments", or when the user explicitly asks to address or fix PR comments. Never infer from unresolved comments.
Send images, audio, video, or documents into an AG2 `Agent` alongside text. Pass `ImageInput`, `AudioInput`, `VideoInput`, or `DocumentInput` as positional args to `agent.ask(...)`. Use when the user wants the agent to process non-text input — describe a photo, transcribe audio, summarise a PDF, analyse a video. Covers per-provider support matrix, the four ways to source data (URL / path / bytes / file_id), Gemini-specific YouTube + media-resolution + clipping, OpenAI image-detail, Anthropic prompt-caching on attachments, and `FilesAPI` for upload lifecycle.
Monitor an AG2 agent's stream — log events, detect repeated tool calls, track token spend, build trigger-driven observers, route observer alerts to the model, and halt on FATAL conditions. Covers `@observer(...)` (stateless), `BaseObserver` (stateful), built-ins (`TokenMonitor`, `LoopDetector`), `Watch` primitives (`EventWatch`, `CadenceWatch`, `DelayWatch`, `IntervalWatch`, `CronWatch`, `AllOf`, `AnyOf`, `Sequence`), `ObserverAlert` (`Severity.INFO/WARNING/CRITICAL/FATAL`), `AlertPolicy`, and `HaltEvent`. Use when the user wants observability, runtime safety guards, alerts, or batch/time-based reactive logic.
Get a typed Python value back from an AG2 `Agent` instead of free text. Pass `response_schema=` (a Pydantic model, dataclass, primitive, union, `ResponseSchema`, or `@response_schema` validator) and read the parsed result via `await reply.content()`. Use when the user wants validated structured output, classification, extraction, or scoring. Covers `ResponseSchema`, `@response_schema`, `PromptedSchema` (for providers without native structured output), per-turn override, validation retries, and primitive embedding.
Test AG2 agents and tools without hitting a real LLM provider. Pass `TestConfig(...)` from `ag2.testing` as the agent's config (or per-`ask`) to mock LLM responses, inject `ToolCallEvent`s to simulate tool execution, and assert success / error paths. Use when the user is writing pytest tests for an Agent or Tool.
