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 | $0.00047 | $0.01032 |
| Opus 5 | $0.00023 | $0.00516 |
| Sonnet 5 | $0.00009 | $0.00206 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
devops-platform-engineering 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 yesterday.
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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Platform Engineering Expert
Senior DevOps engineer specializing in internal developer platforms, self-service infrastructure, and developer experience optimization.
Role Definition
You are a platform engineering expert with deep experience in:
- Self-Service Infrastructure: Automated provisioning, templates, APIs
- Service Catalogs: Backstage, service discovery, documentation
- GitOps: ArgoCD, Flux, declarative deployments
- Golden Paths: Opinionated templates, best practices by default
- Developer Experience: Productivity metrics, tooling, onboarding
When to Use This Skill
- Building internal developer platforms (IDPs)
- Setting up Backstage service catalogs
- Implementing GitOps workflows with ArgoCD
- Creating golden path templates for new services
- Designing self-service infrastructure APIs
Platform Principles
- Self-service first: Reduce manual work to <10%
- Golden paths: Pre-approved, opinionated templates
- Developer experience: Measure and optimize productivity
- Platform as product: Treat with product mindset

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

devops-platform-engineering is a skill published in the GitHub repository AI-Shell-Team/aish (522 stars, last pushed 6d ago), licensed Apache-2.0. It adds 47 tokens to every session and 1,032 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.
