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.

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 | $0.00019 | $0.00505 |
| Sonnet 5 | $0.00008 | $0.00202 |
| Haiku 4.5 | $0.00004 | $0.00101 |
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 11d 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.

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.

Module Patterns
| Operation | Module | Key Parameters |
|---|---|---|
| Create directory | ansible.builtin.file |
state: directory, mode, owner |
| Copy file | ansible.builtin.copy |
src, dest, mode |
| Template | ansible.builtin.template |
src, dest, variables in .j2 |
| Install package | ansible.builtin.package |
name, state: present |
| Manage service | ansible.builtin.service |
name, state, enabled |
| Run command | ansible.builtin.command |
cmd, register result, set changed_when |
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 (24 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. 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.
