Nick MisasiandCursor b4fcb47201 Remove agent-browser skill and lockfile (#36930 )

* Remove agent-browser skill and lockfile

The computerUse subagent now provides a full desktop with Chrome, making
the bespoke agent-browser skill obsolete.

Co-authored-by: Cursor <cursoragent@cursor.com>

* Remove agent-browser install and docs from cloud env

Drop the agent-browser CLI/headless-Chrome install, skip flag, and docs
from the Cursor Cloud Agent Dockerfile, install hook, and notes. Keep the
AWS CLI and the Playwright e2e runtime libraries.

Cursor Cloud Agent Environment

This directory defines the checked-in Cloud Agent environment for this repository. Cursor resolves .cursor/environment.json before personal or team saved environments, so this replaces the snapshot-dependent /onboard flow for agents started from this repo.

The Docker build context is .cursor/ only. The Dockerfile intentionally does not copy the repository; Cursor checks out the requested commit at runtime.

What Is Baked Into The Image

Ubuntu 24.04.
Docker CE 28.5.2 with fuse-overlayfs and iptables-legacy, matching Cursor's Docker-in-Cloud guidance for complex compose setups.
Go 1.25.9 from server/.go-version.
Node 24.11.1/npm 11 via nvm, matching .nvmrc and webapp/package.json.
Browser runtime libraries for the Playwright e2e suite.
AWS CLI v2 for S3 uploads.
Common Mattermost build/test tools: make, jq, xmlsec1, pgloader, Git LFS, GitHub CLI, Python 3, and build essentials.

Runtime Hooks

cloud-agent-install.sh runs after Cursor checks out the repo. It refreshes nvm, verifies Cursor's multi-repo mattermost/enterprise checkout, runs server Go dependency hydration, installs webapp dependencies, and runs Playwright npm ci.
cloud-agent-start.sh materializes .cursor/cursor.md as .cursor/AGENTS.md, fixes current-session Docker socket access, starts Docker, waits until docker info and docker compose version succeed, then logs in to Docker Hub when credentials are configured.

The environment declares github.com/mattermost/enterprise in repositoryDependencies so Cursor can provide it as part of the multi-repo workspace. Cursor currently clones the repositories as siblings, such as /agent/repos/mattermost and /agent/repos/enterprise, which matches server/Makefile's default ../../enterprise path. The install hook does not clone, pull, or symlink enterprise.

Useful Skips

Set these environment variables to true to shorten startup for narrow tasks:

CLOUD_AGENT_SKIP_ENTERPRISE
CLOUD_AGENT_SKIP_GO_DEPS
CLOUD_AGENT_SKIP_WEBAPP_DEPS
CLOUD_AGENT_SKIP_PLAYWRIGHT_DEPS

Expected Secrets

Configure these in the Cursor Cloud Agents dashboard as environment-scoped secrets for the Mattermost Cloud Agent environment.

AWS uploads use the standard AWS CLI environment variables: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_S3_BUCKET_NAME. The image only supplies the aws binary.
Docker Hub pulls use the same variable names as CI: DOCKERHUB_USERNAME and DOCKERHUB_TOKEN. The start hook runs docker login after dockerd is ready. Mark DOCKERHUB_TOKEN as redacted in the dashboard. When both are set, agents can pull the full default make start-docker image set without hitting anonymous rate limits.
