Pulumi Neo Skill

Prerequisites

• Pulumi Cloud account with Neo access
• PULUMI_ACCESS_TOKEN environment variable set with your Personal Access Token
• Organization: Required for all Neo API calls

Detecting Organization

# Get current Pulumi organization from CLI
pulumi org get-default

# If no default org or using self-managed backend, ask user for organization name

If pulumi org get-default returns an error or shows a non-cloud backend, prompt the user for their Pulumi Cloud organization name.

Quick Start

IMPORTANT: Always use --no-poll in Claude Code to prevent blocking.

Preferred: Python Script

python <skill-base-directory>/scripts/neo_task.py --org <org> --message "Your message" --no-poll

Alternative: Direct API

export PULUMI_ACCESS_TOKEN=<your-token>
TIMESTAMP=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
curl -s -X POST "https://api.pulumi.com/api/preview/agents/<org>/tasks" \
  -H "Authorization: token $PULUMI_ACCESS_TOKEN" \
  -H "Accept: application/vnd.pulumi+8" \
  -H "Content-Type: application/json" \
  -d "{\"message\":{\"type\":\"user_message\",\"content\":\"How many stacks do I have?\",\"timestamp\":\"$TIMESTAMP\",\"entity_diff\":{\"add\":[],\"remove\":[]}}}"

Fetch events: curl -s "https://api.pulumi.com/api/preview/agents/<org>/tasks/<task-id>/events" -H "Authorization: token $PULUMI_ACCESS_TOKEN" -H "Accept: application/vnd.pulumi+8" | jq '.events[-1].eventBody.content'

MCP Tools (if Pulumi MCP server is installed): mcp__pulumi__neo-bridge, mcp__pulumi__neo-get-tasks, mcp__pulumi__neo-continue-task

Using the Python Script

The script handles Neo task creation, polling, and management:

# Create a task and poll for updates (interactive/terminal use)
python scripts/neo_task.py --org <org-name> --message "Help me optimize my Pulumi stack"

# Create task without polling (CI/CD or programmatic use)
python scripts/neo_task.py --org <org-name> --message "Analyze this" --no-poll

# Create task with stack context
python scripts/neo_task.py --org <org-name> \
  --message "Analyze this stack" \
  --stack-name prod --stack-project my-infra --no-poll

# Create task with repository context
python scripts/neo_task.py --org <org-name> \
  --message "Review this infrastructure code" \
  --repo-name my-repo --repo-org my-github-org --no-poll

# List existing tasks
python scripts/neo_task.py --org <org-name> --list

# Fetch current events (single request, no polling)
python scripts/neo_task.py --org <org-name> --task-id <task-id> --get-events

# Poll an existing task for updates (interactive)
python scripts/neo_task.py --org <org-name> --task-id <task-id>

# Send approval for a pending request
python scripts/neo_task.py --org <org-name> --task-id <task-id> --approve

# Cancel a pending request
python scripts/neo_task.py --org <org-name> --task-id <task-id> --cancel

Neo Task Workflow

Creating Tasks

Tasks are created with a natural language message describing what you want Neo to do:

• Infrastructure analysis: "Analyze my production stack for security issues"
• Maintenance operations: "Help me upgrade my Kubernetes cluster"
• Configuration changes: "Add monitoring to my Lambda functions"
• Multi-step workflows: "Set up a complete CI/CD pipeline for this project"

Entity Context

Attach entities for context: stack (name + project), repository (name + org + forge), pull_request (number + merged + repository), policy_issue (id).

Task Status

Status	Description
running	Neo is actively processing the task
idle	Task is waiting for input or has finished processing

Note: Task completion and approval requests are determined by examining events, not task status.

Approval Flow

When Neo requires confirmation for an operation (this is a key concept — Neo never makes destructive changes without asking):

1. Task status remains running or transitions to idle
2. An agentResponse event contains tool_calls with an approval_request tool — this is the specific event structure to look for
3. The approval_request_id is found in the tool call parameters
4. User reviews the proposed changes
5. Send approval via --approve or cancellation via --cancel

Detecting approvals: Check events for eventBody.tool_calls containing approval_request entries rather than relying on task status. The approval_request_id from the tool call parameters is needed to respond.

# Approve a pending request
python scripts/neo_task.py --org <org> --task-id <task-id> --approve

# Cancel/reject a pending request
python scripts/neo_task.py --org <org> --task-id <task-id> --cancel

Common Workflows

Analyze Infrastructure

python scripts/neo_task.py --org myorg \
  --message "What security improvements can I make to my AWS infrastructure?" \
  --stack-name prod --stack-project aws-infra --no-poll

Fix Policy Violations

python scripts/neo_task.py --org myorg \
  --message "Help me fix the policy violations in my production stack" --no-poll

Generate Pulumi Code

python scripts/neo_task.py --org myorg \
  --message "Create a new Pulumi TypeScript project for a containerized web app on AWS ECS" --no-poll

Review Pull Request

python scripts/neo_task.py --org myorg \
  --message "Review the infrastructure changes in this PR" \
  --repo-name infra --repo-org myorg --repo-forge github --no-poll

Troubleshooting

Error	Cause	Solution
401	Invalid/missing token	Verify with curl -s -H "Authorization: token $PULUMI_ACCESS_TOKEN" https://api.pulumi.com/api/user
404	Wrong org or endpoint	Verify org with pulumi org get-default
409	Task busy	Wait for current operation to complete
Script hangs	Missing --no-poll	Kill with Ctrl+C, add --no-poll flag
Token not found	Not exported	Run export PULUMI_ACCESS_TOKEN="$PULUMI_ACCESS_TOKEN"
