Claude Cowork adds finance workflow plugins

This is less about “AI for finance” hype and more about Anthropic productizing prompt engineering into reusable workflow software. The interesting move is that Anthropic is packaging domain expertise, MCP connectors, slash commands, and sub-agents as installable plugins instead of pretending raw model intelligence is enough.

• –The repo ships a core financial-analysis plugin plus role-specific add-ons, which suggests Anthropic wants Cowork to win through repeatable vertical workflows rather than generic chat
• –Anthropic says the bundle includes 41 skills, 38 commands, and 11 MCP integrations, connecting Claude to providers like FactSet, PitchBook, Moody’s, Morningstar, LSEG, and S&P Global
• –The plugins generate real work products like Excel models, IC memos, pitch decks, and earnings reports, which is much more concrete than the usual “agent for knowledge work” pitch
• –Because the components are file-based markdown and JSON, firms can customize process, templates, and connectors without building full internal agent infrastructure
• –The bigger takeaway for developers is architectural: Cowork is becoming a plugin marketplace for domain-specific agent behavior, with finance as one of the first serious vertical examples
