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 | $0.00038 | $0.01529 |
| Opus 5 | $0.00019 | $0.00764 |
| Sonnet 5 | $0.00008 | $0.00306 |
| Haiku 4.5 | $0.00004 | $0.00153 |
Grade A, and why
inventory-manager 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 4d 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.

Inventory Manager
Quick Start
Organize Ansible inventory with proper host groups, variables, and dynamic inventory sources.
Instructions
Step 1: Create static inventory
INI format:
# inventory/production
[webservers]
web1 ansible_host=192.168.1.10
web2 ansible_host=192.168.1.11
[databases]
db1 ansible_host=192.168.1.20
db2 ansible_host=192.168.1.21
[loadbalancers]
lb1 ansible_host=192.168.1.30
[production:children]
webservers
databases
loadbalancers
[production:vars]
ansible_user=deploy
ansible_python_interpreter=/usr/bin/python3
environment=production
YAML format:
# inventory/production.yml
all:
children:
production:
children:
webservers:
hosts:
web1:
ansible_host: 192.168.1.10
web2:
ansible_host: 192.168.1.11
databases:
hosts:
db1:
ansible_host: 192.168.1.20

loadbalancers:
hosts:
lb1:
ansible_host: 192.168.1.30
vars:
ansible_user: deploy
environment: production
Step 2: Organize group variables
Directory structure:
inventory/
├── production
├── staging
├── group_vars/
│ ├── all.yml
│ ├── webservers.yml
│ ├── databases.yml
│ └── production.yml
└── host_vars/
├── web1.yml
└── db1.yml
group_vars/all.yml:
---
# Variables for all hosts
ansible_python_interpreter: /usr/bin/python3
ntp_servers:
- 0.pool.ntp.org
- 1.pool.ntp.org
group_vars/webservers.yml:
---
# Variables for webservers group
nginx_port: 80
nginx_worker_processes: 4
app_directory: /var/www/app
group_vars/production.yml:
---
# Variables for production environment
environment: production
backup_enabled: true
monitoring_enabled: true
Step 3: Configure host-specific variables
host_vars/web1.yml:
---
nginx_worker_connections: 1024
server_id: 1
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.

inventory-manager is a skill published in the GitHub repository armanzeroeight/fastagent-plugins (29 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 1,529 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.
