Quoin

quoin is a bundle of Quire modules, agent skills, and workflows for authoring ISO/IEC/IEEE 29148-aligned software specifications and other technical documents. It includes prepackaged modules for the spec vocabulary and ideation/authoring/review/planning workflows agents need to write and validate specs directly as Markdown.

quoin is built on the Quire document standard and validation engine by Agent-IX.

Why: AI agents write code fast but drift from vague intent. Quoin makes the spec the source of truth — your agent authors a validated, traceable spec first, then plans and builds against it.

How

In Claude Code, Codex, or the coding agent of your choice:

1. Ideate & Specify

Ideate, then pass your idea to /specify. A specification containing user stories, functional requirements, stakeholder requirements, non-functional requirements, and other artifacts will be created.

> /specify an electron app for tracking spice production

2. Spec Review

Use /spec-review for agent-assisted review. Multiple analysis tasks will run in parallel and output Reviews with Findings and suggested fixes.

> /spec-review review the specs for the spice production tracker.

3. Convert to plans

Build the test traceability matrix and plan. These skills will break the work down into a plan with multiple tasks.

> /spec-matrix /spec-to-plan prep the spice tracking app for coding

4. Implement!

Call /implement-plan to trigger your coding agent to begin work on the plan.

> /implement-plan build the spice tracking app

5. Gap review

/gap-analysis validates that the UserStory and Functional Requirements are implemented and tested using the traceability matrix as the guide. /gap-analysis will optionally perform a semantic comparison of spec, code, and tests to ensure the plan is faithfully implemented.

What's included

The default module set defines the spec archetypes and domain-object vocabulary.

Artifact archetypes — the document types you author:

Module	Archetypes
spec-artifacts-iso	StR, FR, NFR, US, IT, TC, Spec, master-requirements
spec-artifacts-app	ApplicationSpec, MasterRequirements
spec-artifacts-process	ADR, Plan, Task, Review, Finding, TestMatrix, Standard

Domain objects — prefab templates for common objects
