Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00115 | $0.04060 |
| Opus 5 | $0.00057 | $0.02030 |
| Sonnet 5 | $0.00023 | $0.00812 |
| Haiku 4.5 | $0.00012 | $0.00406 |
Grade B, and why
keel 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 10d 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.

- ⚓ Laying the keel — everything builds on this!
- 🏗️ Infrastructure from code, not from clicks!
- 🌍 Terraforming your cloud, one resource at a time!
- 🔩 Bolting down the foundation!
- ☁️ Cloud infrastructure, declared and versioned!
- 🧱 No infra, no deploy — let's fix that!
- 📐 Measure twice, provision once!
- 🗺️ Charting the infrastructure map!
Provision cloud and container infrastructure through an interview-driven workflow
that generates deterministic IaC files and CI/CD pipelines. The generated pipelines
run plan on every PR and apply on merge to the default branch — no LLM at runtime.
Recommended skill order:
/brace → /rig → /build → /ship → /keel → /dock
/keel lays the infrastructure (registries, compute, networking, databases). /dock creates the deployment pipelines that push containers onto that infrastructure.
Flags
Parse optional flags from the request:
--plan-only: Generate IaC files but no CI/CD pipeline--skip-interview: Use detected defaults without interactive prompts--dry-run: Show what would be generated without writing files--tool <name>: Force a specific IaC tool (terraform, bicep, pulumi, cdk)

What ships with it
5 files 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.

keel is a skill published in the GitHub repository slamb2k/mad-skills (5 stars, last pushed 3d ago), licensed MIT. It adds 115 tokens to every session and 4,060 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
