What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is Twist?
A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.
This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.

Slack
6.3COMMSCOLLAB
Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
Twist
0.0COMMS
A French telecom-fleet management tool quietly shipping fixes — no recent activity in over a year.
◆ Current state
This Twist is not Doist's messaging app — it's a French B2B platform for managing corporate mobile telecom fleets (lines, SIM cards, terminal inventory, operator orders). The visible window is dominated by small audit-module fixes, SIM validation tweaks, mail parser improvements and one earlier Bouygues operator API connector. The most recent shipping activity dates to September 2024.
◆ Where it's heading
The trajectory in the captured window points to operational maintenance rather than category expansion: tightening data validation, fixing edge cases in audit reporting, supporting more telecom-data formats. The earlier Bouygues API connector hinted at a machine-to-machine ambition with the major French carriers, but follow-through (Orange, SFR) is not visible in this window. Public release cadence appears to have gone quiet.
◆ Prediction
Hard to call from the visible entries. If the Orange and SFR API connectors promised in 2024 ever shipped, they would have been the natural next chapter; their absence suggests either delayed delivery or a move to private release notes. Watch for whether public changelog cadence resumes at all.
