From b17def3cd9ca6d18f5936c6f3d902b7c5504681c Mon Sep 17 00:00:00 2001 From: dhruv-15-03 Date: Fri, 3 Jul 2026 22:05:02 +0530 Subject: [PATCH] feat(extensions): add EARS requirements syntax extension (#1356) Add a bundled first-party extension that brings EARS (Easy Approach to Requirements Syntax) to Spec Kit. EARS constrains each requirement to one of five sentence patterns built around the mandatory modal "shall", producing unambiguous, testable requirements. The extension provides three explicit commands, mirroring the structure of the bundled bug extension and writing artifacts under .specify/ears//: - speckit.ears.author - draft requirements for a feature directly in EARS - speckit.ears.lint - read-only audit of existing requirements for EARS conformance and ambiguity, with suggested rewrites - speckit.ears.convert - rewrite free-form requirements into EARS and emit an original-to-EARS traceability matrix The extension is optional and additive: it changes no core templates and no default behavior, and is registered as a bundled catalog entry alongside the existing agent-context, bug, and git extensions. Adds tests/extensions/ears covering the bundled layout, catalog registration, bundle resolution, and install via ExtensionManager.

Each command reads and writes Markdown under `.specify/ears//`, keeping EARS work self-contained and optional. + +## Overview + +EARS was developed at Rolls-Royce to remove ambiguity from natural-language requirements and is widely used in aerospace, automotive, and other safety-critical domains. It constrains each requirement to one of five patterns built around the mandatory modal **shall**: + +| Pattern | Template | +|---------|----------| +| **Ubiquitous** | The `` shall ``. | +| **Event-Driven** | When ``, the `` shall ``. | +| **State-Driven** | While ``, the `` shall ``. | +| **Unwanted Behavior** | If ``, then the `` shall ``. | +| **Optional Feature** | Where ``, the `` shall ``. | + +This extension delivers three commands that any AI coding agent can drive: + +1. **Author** - turn a feature idea into a fresh EARS requirements set. +2. **Lint** - audit existing requirements for EARS conformance and ambiguity (read-only). +3. **Convert** - rewrite free-form requirements into EARS with a traceability matrix. + +The commands communicate through Markdown files in a single per-topic directory: + +``` +.specify/ears// +├── requirements.md # written by speckit.ears.author and speckit.ears.convert +└── lint-report.md # written by speckit.ears.lint +``` + +## Commands + +| Command | Description | Output | +|---------|-------------|--------| +| `speckit.ears.author` | Drafts requirements for a feature directly in EARS format, classified by pattern. | `.specify/ears//requirements.md` | +| `speckit.ears.lint` | Audits existing requirements for EARS conformance and ambiguity, with suggested rewrites. | `.specify/ears//lint-report.md` | +| `speckit.ears.convert` | Rewrites free-form requirements into EARS and records original-to-EARS traceability. | `.specify/ears//requirements.md` | + +## Slug Conventions + +A *slug* is the per-topic directory name under `.specify/ears/`.

A generated slug **MUST** produce a unique directory for new work - if `.specify/ears//` already exists, the agent appends the shortest disambiguating suffix needed (`-2`, `-3`, …) or a short date (`-20260605`).
