Guidance for writing Ansible playbooks, roles, and inventory files. Ansible is a tool that configures computers from YAML files describing the desired system setup.

Creating Ansible projects, installing packages, managing services, copying files, and configuring servers. It also helps diagnose failed automation.

It helps avoid repeated manual setup and common YAML, module, and variable errors. Re-running the same instructions can keep systems in the intended state without unnecessary changes.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add ibm-self-serve-assets/building-blocks --skill playbook

Clone the repo

git clone --depth 1 https://github.com/ibm-self-serve-assets/building-blocks

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.01011
Opus 5.5	$0.00016	$0.00404
Sonnet 5.5	$0.00008	$0.00202
Haiku 4.5	$0.00004	$0.00101

Security

Grade B, and why

playbook scanned grade B with 1 finding 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 2mo 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ansible Playbook Development

Ansible playbooks declare desired system state rather than imperative commands. The core principle is idempotency: running a playbook multiple times produces the same result without unintended changes.

What this file has done since we first saw it

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 is a skill published in the GitHub repository ibm-self-serve-assets/building-blocks (28 stars, last pushed yesterday), licensed Apache-2.0. It adds 39 tokens to every session and 1,011 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
