Aero Agent Skills

The aerospace knowledge layer for AI agents.

Standards-mapped skills that give a coding agent the certification process, not just the acronyms. Every skill is a verified workflow: the steps, the pitfalls, the gates, and the human sign-off.

WHAT SHIPS

Skills that carry their own proof.

A skill here is not a prompt. It is an engineering workflow with the evidence attached, built to be loaded by an AI agent the moment a task matches it.

Verified, not scraped

Each skill ships a workflow with verification gates, a behavior contract in plain stdlib unittest, and router assertions that prove the right skill loads for the right task.

Standards as the spine

Skills are mapped to 30 aerospace standards: ECSS, DO-178C, DO-254, ARP4754A, NASA handbooks and more. The agent follows the process the certification authority expects.

Open format, no lock-in

Plain SKILL.md files on the open AgentSkills.io format, licensed Apache-2.0. Any agent host that loads skills can load these.

DOMAIN COVERAGE

The whole discipline, measured.

Coverage is not claimed, it is plotted: verified skills against the router assertions that exercise them, family by family.

The inner ring is the 12 engineering families. The outer ring is every installable pack, sized by the verified skills inside it. The chart is computed from the tree at HEAD on every change: if a skill lands, the arc grows.

TWELVE FAMILIES

From airfoil to airworthiness.

Every family is anchored to the standards an aerospace engineer would actually be held to.

HOW IT WORKS

Deterministic in, human out.

A deterministic router picks the skill by its description, the workflow loads with its gates and standards context, and the terminal node is always a human sign-off.

STOP GATE:

FAIL-CLOSED VERIFICATION

Every claim is a gate.

Every push replays five validation gates and three attestation gates, offline and deterministic. A red gate blocks the push: the repository cannot drift from its claims. The same battery regenerates every figure and chart on this page.

PAIRS WITH

Skills become roles.

A skill does one task correctly. Aero Agent Roles binds the right skills into a role that owns a whole deliverable, in order, with evidence gates and a human sign-off. Same repository standard, same gate battery, built to be used together.

Explore Aero Agent Roles

The software product assurance skills for ECSS-Q-ST-80C, the European Cooperation for Space Standardization standard, run on your own evidence. Ashforde OÜ offers a five-day evidence pilot built on these open skills and the Software Product Assurance Engineer role: a clause-by-clause draft compliance matrix, a gap list and a trace to your own files, with a signed record you can check offline, stopping at your own human sign-off.
