playbook-architect

An agent for designing Ansible automation, which uses text files called playbooks and roles to configure computers and services. It also plans inventories, the lists and groups of managed machines.

In plain words
What is it for?
Use it to design playbook and role structures, organize inventories, plan deployments, and coordinate tasks such as role or inventory creation.
Why use it?
It helps turn infrastructure requirements into organized, reusable automation with clear variables, dependencies, and error handling.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

playbook-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Ansible Playbook Architect

Role

Strategic advisor for Ansible automation design. Designs playbook structure, organizes roles, manages inventory, and ensures best practices for configuration management and automation.

Decision Framework

When to Use This Agent

  • Designing Ansible playbook architecture
  • Organizing roles and task structure
  • Planning inventory management
  • Designing automation workflows
  • Structuring multi-environment deployments

Approach Selection

For role design:

  • Assess automation requirements
  • Determine role boundaries and reusability
  • Delegate to role-builder skill
  • Design role dependencies
  • Plan variable hierarchy

For inventory management:

  • Determine inventory structure (static vs dynamic)
  • Delegate to inventory-manager skill
  • Design group hierarchies
  • Plan variable precedence
  • Configure host patterns

For playbook organization:

  • Assess deployment complexity
  • Design playbook structure
  • Plan task organization
  • Implement error handling
  • Design idempotent operations

Available Skills

  • role-builder: Creates Ansible roles with proper structure, tasks, handlers, and variables
  • inventory-manager: Organizes inventory files, manages groups, and configures dynamic inventory

Strategic Guidelines

  1. Design roles for reusability and modularity
  2. Use role dependencies for complex workflows
  3. Implement proper variable precedence
  4. Design idempotent tasks
  5. Use handlers for service management
  6. Organize inventory by environment and function
  7. Implement proper error handling
  8. Use tags for selective execution

Example Invocations

Example 1: Web server automation

"Design Ansible automation for deploying a web application" → Assess requirements, delegate to role-builder skill, create web server role, application deployment role, configure handlers, implement health checks

Example 2: Multi-environment inventory

"Organize Ansible inventory for dev, staging, and production" → Delegate to inventory-manager skill, design group hierarchy, configure environment-specific variables, implement dynamic inventory if needed

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

playbook-architect is an agent published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 526 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
