User-facing 'Stop' action button for agents within Slack session blocks.

Technical Positioning
Enhancing user control and agent management within collaborative chat environments, specifically for halting runaway or undesirable agent actions.
SaaS Insight & Market Implications
The absence of a direct 'Stop' button for agents in Slack threads represents a critical usability and control deficiency. Users are currently forced into complex API calls or sandbox commands to halt runaway agents, a process inaccessible to most. This directly impacts user trust and productivity in agent-driven workflows. Implementing a visible, accessible stop mechanism is essential for managing agent behavior in real-time, preventing resource waste, and improving the overall user experience in collaborative environments. This highlights a market need for intuitive, immediate control over autonomous systems, particularly in enterprise communication platforms where user intervention must be frictionless.

Raw Developer Origin & Technical Request

Repo: paradigmxyz/centaur
Add a "Stop" action button to the Slack session block

## Problem

The Slack session block (the bot's status card in a thread) exposes interactive actions for the running agent, but there is no user-facing way to stop the agent from the thread itself. Today, the only way to halt a runaway turn is via the API (`POST /agent/stop` → `agent_release_requests`) or `call agent stop` from another sandbox — neither of which is reachable for normal Slack users.

This came up in a live thread where the agent kept producing follow-ups that the user wanted to cancel; the user explicitly asked for "an action to stop the agent."

## Proposal

Add a **Stop** button to the Slack session block renderer that:

1. Is shown while the agent is busy (mirrors the existing `busy` state already tracked in `agent/status`).
2. On click, dispatches to the same code path as `call agent stop` / `agent_release_requests` for the active `thread_key`.
3. Visually transitions the block to a "stopped by " state once the release is acknowledged, similar to how completion is rendered today.
4. Is restricted to thread participants (or at minimum, the original requester + workspace admins) to avoid drive-by cancels.

Maybe it could also be useful to add a Retry button in case a job fails. For example, in the image below, the job failed, but the bot didn’t send any feedback

hmm - we already have steering / stopping using `@ stop` - do you think a stop button would be better UX here?

Closing as we are unlikely to introduce other ways to interact with Centaur outside of natural language back and forth. We can always re-open later if we want to add some common quick actions pattern later.

Makes sense - wanna do a stab at it? Also @pseudolabel cc re subscriptions

Happy to! I have a local workaround which passes the smoke test but requires iron-proxy changes. Will look for something more robust over the weekend

Manual chart publish completed from the sandbox as a workaround for the failed Release Chart workflow. Evidence: - `gh-pages` updated to commit `068587e390b13fd80b7a82d4c948248276a1a174` with `cent...

The patch in the issue body is enough to land this as a very small workflow PR: - replace `git switch -` with an explicit `${GITHUB_REF_NAME:-main}` switch after orphan bootstrap - add the 1Passwor...
