Cloud Agents

Cloud Agents

Manage Cursor Cloud Agents through the REST API at https://api.cursor.com/v0.

Prerequisites

• CURSOR_API_KEY environment variable must be set
• jq must be installed (used by the helper script)
• If the key is not set, ask the user to provide it or set it: export CURSOR_API_KEY=<key>
• Keys are created at https://cursor.com/settings

Inferring the Repository

When the user does not specify a repo URL, infer it from the current working directory:

git remote get-url origin

This gives you the GitHub URL to pass to launch. Also infer the current branch with git branch --show-current to use as the ref unless the user specifies otherwise.

Error Handling

If any step fails (API call, git operation, image encoding, etc.), do not attempt to automatically fix or retry. Instead, clearly report the error to the user: what command failed, the error message, and suggest what they can do about it. Let the user decide the next step.

Helper Script

All API calls go through scripts/cloud-agent.sh (relative to this skill directory). Execute it via the Shell tool.

SKILL_DIR="$HOME/.cursor/skills/cloud-agents"
"$SKILL_DIR/scripts/cloud-agent.sh" <command> [args...]

Commands Reference

List agents

"$SKILL_DIR/scripts/cloud-agent.sh" list          # default 20
"$SKILL_DIR/scripts/cloud-agent.sh" list 50        # up to 100

Pipe through jq for readable output:

"$SKILL_DIR/scripts/cloud-agent.sh" list | jq '.agents[] | {id, name, status, branch: .target.branchName, pr: .target.prUrl}'

Check agent status

"$SKILL_DIR/scripts/cloud-agent.sh" status <agent_id> | jq .

Statuses: CREATING, RUNNING, FINISHED, STOPPED, ERROR

Get conversation history

"$SKILL_DIR/scripts/cloud-agent.sh" conversation <agent_id> | jq '.messages[] | {type, text}'

Launch a new agent

"$SKILL_DIR/scripts/cloud-agent.sh" launch \
  "https://github.com/org/repo" \
  "Your prompt here" \
  main \       # ref (optional, default: main)
  true \       # auto-create PR (optional, default: false)
  "" \         # model (optional, empty = auto)
  "my-branch"  # custom branch name (optional)

Launch agent on an existing PR

"$SKILL_DIR/scripts/cloud-agent.sh" launch-pr \
  "https://github.com/org/repo/pull/123" \
  "Fix the failing tests"

Send follow-up

"$SKILL_DIR/scripts/cloud-agent.sh" followup <agent_id> "Also add tests"

Attaching images

Images can be appended as trailing file paths to launch, launch-pr, and followup (max 5). The script base64-encodes them and extracts dimensions via sips.

"$SKILL_DIR/scripts/cloud-agent.sh" launch \
  "https://github.com/org/repo" \
  "Implement this design" \
  main false "" "" \
  /path/to/mockup.png /path/to/reference.jpg

"$SKILL_DIR/scripts/cloud-agent.sh" followup <agent_id> \
  "The button should look like this instead" \
  /path/to/screenshot.png

When the user attaches an image in the conversation, resolve its absolute file path and pass it as a trailing argument.

Stop / Delete

"$SKILL_DIR/scripts/cloud-agent.sh" stop <agent_id>
"$SKILL_DIR/scripts/cloud-agent.sh" delete <agent_id>

Utility

"$SKILL_DIR/scripts/cloud-agent.sh" me       # API key info
"$SKILL_DIR/scripts/cloud-agent.sh" models   # available models
"$SKILL_DIR/scripts/cloud-agent.sh" repos    # accessible GitHub repos (rate-limited: 1/min)

Pulling Agent Changes Locally

After an agent finishes (or while it's running), pull its changes into the local repo.

Step 1: Get the agent's branch name

BRANCH=$("$SKILL_DIR/scripts/cloud-agent.sh" status <agent_id> | jq -r '.target.branchName')

Step 2: Fetch and checkout

git fetch --all
git checkout "$BRANCH"
git pull origin "$BRANCH"

Step 3: Cherry-pick onto current branch (alternative)

If the user wants to apply agent commits onto their current branch instead of switching:

git fetch --all
CURRENT=$(git branch --show-current)

# Find commits the agent made (commits on agent branch not on current)
COMMITS=$(git log --oneline "$CURRENT".."origin/$BRANCH" --reverse --format='%H')

for commit in $COMMITS; do
  git cherry-pick "$commit"
done

Step 4: Merge (alternative)

git fetch --all
git merge "origin/$BRANCH"

Step 5: Diff review

git fetch --all
git diff HEAD..."origin/$BRANCH"

Workflow: Launch and Monitor

1. Launch the agent
2. Poll status every 15-30 seconds until FINISHED or ERROR
3. If FINISHED, show summary and ask user how to apply changes (checkout / cherry-pick / merge)
4. If ERROR, show conversation to diagnose

Workflow: Review Running Agents

1. List agents, filter by RUNNING status
2. For each, show id, name, branch, time since creation
3. Offer to check conversation, send follow-up, or stop
