Engineering Assurance

Engineering Assurance is the Agent IX assurance module for making engineering decisions explicit, reviewable, and owned by a person. It gives a coding agent one canonical onboarding skill and four resumable workflows for deciding what assurance work a repository actually needs.

It is deliberately not a compliance oracle. Engineering Assurance does not calculate a trust score, import external rules, or approve a release. The decision owner remains responsible for the boundary, claims, exceptions, evidence sufficiency, and terminal decision.

How it fits

Engineering Assurance is a small part of the Agent IX documentation toolchain:

Quire-rs validates the artifacts, Quoin installs and composes the modules, and ix-flow records the workflow lifecycle.

This module uses the Rust quire-rs engine through quire-cli

Install

1. Install the toolchain

These are the versions recorded in engineering_assurance/compatibility-matrix.json:

npm install --global \
  @agent-ix/quire-cli@0.31.0 \
  @agent-ix/quoin@0.23.1 \
  @agent-ix/ix-flow@0.2.3
rustup toolchain install 1.98.1

Install the unpublished native CLI from the tagged source checkout:

cargo +1.98.1 install \
  --git https://github.com/agent-ix/engineering-assurance \
  --tag v0.3.1 \
  --locked \
  --bin engineering-assurance

2. Install the Quire module

Install the module directory from the same tag. The //engineering_assurance suffix selects the module root inside this repository:

quoin module install \
  github:agent-ix/engineering-assurance//engineering_assurance@v0.3.1

The installed module contains manifest.yaml, schemas/, and skeletons/. Quire-rs consumes those files when validating assurance artifacts.

3. Install the agent skill

The same assurance-onboarding skill is available to Claude Code, Codex, OpenCode, and GitHub Copilot. Use the section for your agent.

/plugin marketplace add agent-ix/engineering-assurance
/plugin install engineering-assurance@engineering-assurance

codex plugin marketplace add agent-ix/engineering-assurance
codex plugin add engineering-assurance@engineering-assurance

gh skill install agent-ix/engineering-assurance \
  engineering_assurance/skills/assurance-onboarding \
  --pin v0.3.1 \
  --scope user \
  --agent opencode

copilot plugin marketplace add agent-ix/engineering-assurance
copilot plugin install engineering-assurance@engineering-assurance

gh skill install agent-ix/engineering-assurance \
  engineering_assurance/skills/assurance-onboarding \
  --pin v0.3.1 \
  --scope user \
  --agent github-copilot

What it provides

Artifact types

The module supplies Quire schemas and Markdown skeletons for five artifact types:

Agent skill and workflows

Ask the agent to use assurance-onboarding and provide the repository root, exact decision boundary, and human decision owner. The skill inventories before proposing anything and preserves malformed or conflicting existing artifacts.

It routes bounded work through these ix-flow definitions:

Example prompt:

Use assurance-onboarding for this repository. The decision boundary is the
database migration in this change, and Jane Doe owns the terminal decision.
Inventory the existing assurance context before proposing work.

Validate Markdown documents with quire-cli (the quire-rs-backed CLI):

quire validate --scope . 'spec/**/*.md'

Native CLI reference

The native CLI is primarily an automation boundary. Every stdin/stdout protocol is versioned and documented by the schemas under engineering_assurance/schemas/.

Run engineering-assurance --help or engineering-assurance <command> --help for argument details. Maintainer-only commands do not make a release decision and should not be invoked as a substitute for the human workflow gates.
