Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 23 stories with headroom
What would move Slack’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Agenticness — how well agents can access and operate the productPlug MCP servers into this product so it can use their tools
nonemoves agent-readyimpact 45
All evidence describes Slack exposing its own official MCP server so external AI clients (Claude, ChatGPT, custom agents) can call Slack's tools — the reverse direction of this story, which asks whether a user can plug external MCP servers into Slack so Slack's own agents (e.g., Slackbot) can use their tools.
Openness — open source, data portability, and self-hosting storiesSelf-host the core product
nonemoves PA Scoreimpact 30
Slack is a cloud SaaS product; the evidence pack shows only hosted/cloud offerings, developer sandboxes, CLI, SDKs, and export tools—no self-hosted deployment option is documented anywhere, and community evidence even discusses difficulty exporting data or migrating off Slack's hosted service.
Channels threads — stories about channels threads in this arenaOrganize conversations into public and private channels with membership controls
nonemoves PA Scoreimpact 30
The evidence pack focuses almost entirely on Slack's AI/MCP tooling, developer SDKs, huddles, and integrations, with no first-party documentation describing channel creation, public vs.
Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models
nonemoves PA Scoreimpact 30
No evidence in the pack addresses AI training data opt-out or controls preventing Slack/customer data from being used to train AI models; the pack covers unrelated AI features (search, summarization, MCP server) and export/pricing controversies but nothing about AI-training data usage or opt-out settings.

Missing: official docs/screenshots describing thread-reply UX, independent confirmation that reply notifications and thread views work smoothly, and resolution of the cited usability complaints.
Compliance exports — stories about compliance exports in this arenaReview audit logs of admin and user actions across the workspace
nonemoves PA Scoreimpact 20
The evidence pack includes only workspace data export/import documentation (e.g., slack-docs-22/23/35/36) and community complaints about export restrictions (slack-comm-2), but nothing that documents an audit log capability tracking admin and user actions across the workspace.
Automation depth — how much of the product can run unattendedPerform bulk operations across many items at once
nonemoves PA Scoreimpact 20
Slack's Web API and MCP server document single-item actions (send one message, upload one file, create one list entry, etc.) with no documented batch/bulk endpoints or MCP tools for operating across many items in one call.
