Shortcut vs Slack
Side-by-side trajectory, velocity, and editorial themes.
Shortcut is rebuilding its API for agents and pushing its Korey AI assistant beyond the app.
Two real threads run through the recent log: an API overhaul (coarse-grained token scopes, admin-scoped routes, and a v4 alpha explicitly aimed at agent compatibility) and the Korey AI assistant expanding to a Chrome extension usable on any webpage. Integration and roadmap polish round it out. Note that some recent feed items are brand-guide page content rather than product releases.
Shortcut is preparing its platform for agent-driven use, with scoped tokens and an agent-optimized API v4, while extending Korey outward from inside the app to anywhere the user works. The direction is a project tracker that both AI agents and humans can drive through a controlled API.
Expect API v4 to move from alpha toward general availability with agent-oriented capabilities, and Korey to gain more in-context actions across surfaces beyond the Chrome extension.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
