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 | $0.00029 | $0.00747 |
| Opus 5.5 | $0.00012 | $0.00299 |
| Sonnet 5.5 | $0.00006 | $0.00149 |
| Haiku 4.5 | $0.00003 | $0.00075 |
Grade A, and why
packer-cli 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 23d 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Packer CLI Skill
Use the template table and rules below when constructing all packer commands.
Configuration
Update the table below with your Packer template files and target build environments:
| Environment | Template File | Variables File |
|---|---|---|
| Production | <your-prod-template>.pkr.hcl |
<your-prod.pkrvars.hcl> |
| Staging / Non-Prod | <your-nonprod-template>.pkr.hcl |
<your-nonprod.pkrvars.hcl> |
If the target environment is unclear, ask the user before running any command.
Prerequisites (one-time setup by user)
If packer is not installed, inform the user that setup is required and ask them to complete the following steps manually. Do not perform these steps yourself.
brew install packer
packer init <template.pkr.hcl>
Command Format
packer <command> -var-file=<vars-file> <template.pkr.hcl>
Examples
# Non-Prod — validate before building
packer validate -var-file=<your-nonprod.pkrvars.hcl> <your-nonprod-template>.pkr.hcl
# Non-Prod — build (only with user confirmation)
packer build -var-file=<your-nonprod.pkrvars.hcl> <your-nonprod-template>.pkr.hcl
Available Commands
Read-only (safe, no confirmation needed)
| Command | Description |
|---|---|
packer validate -var-file=<file> <template> |
Validate template syntax and configuration |
packer fmt -check -diff <template> |
Check formatting without modifying the file |
packer inspect <template> |
Show builders, provisioners, and variables defined |
packer console |
Open an interactive expression evaluator |
packer version |
Show Packer version |
Mutating operations (confirm with user before running)
| Command | Description |
|---|---|
packer build -var-file=<file> <template> |
Build a new machine image — provisions real cloud/VM resources during the build |
packer fmt <template> |
Reformat a template file in place |
packer init <template> |
Install required plugins |
Never run — requires explicit human approval
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.

packer-cli is a skill published in the GitHub repository abdullahkhawer/devops-skills (8 stars, last pushed 24d ago), licensed Apache-2.0. It adds 29 tokens to every session and 747 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-23.
