Perform a thorough quality review of a pull request or feature branch before merging. Use this skill whenever the user asks to review a PR, check if code is production-ready, assess quality, verify docs are updated, or asks "is this ready to merge?", "review this PR", "check quality", "is this production ready?", or similar. Also use when reviewing your own work before submitting.
Configure consent (opt-in/opt-out) on an Enhanced `MessagingChannel` so activation will accept it. Given a `{CHANNEL_ID}`, sets the channel's `ConsentType` (ImplicitOptIn / ExplicitOptIn / DoubleOptIn) and the `OptInPrompt` / `DoubleOptInPrompt` prompt fields, then creates or updates one `MsgChannelLanguageKeyword` record per language holding the opt-in / double-opt-in / opt-out / help / custom keywords and confirmation messages. Use between channel insertion and activation — activation fails the consent-readiness check unless a valid ConsentType and at least one matching language-keyword record exist.

Role and tier are assessed per system, not per company. Use when the user says "ai inventory", "add an ai system", "what systems do we have", "classify this ai system", "eu ai act register", or "ai system registry."
Build a deposition outline for a witness — pull their documents from the eDiscovery platform, organize topics around the case theory, and surface impeachment material. Use when the user says "depo prep for [witness]", "build a depo outline", or "prepare for [name]'s deposition".
Generate and edit images using OpenAI's GPT Image 1.5 model. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y").

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.
