Turn PRDs into Ready-to-Use Test Plans with AI: The Requirements Analysis Skill in TRAE IDE

Problem statement

PRDs are long, fragmented, frequently changed, and often lack clear documentation, causing difficulty in determining test scope, missed regressions, and reliance on subjective priority decisions. The core inefficiency is the low conversion rate from requirements to test assets.

Skill functionality

After importing, the AI transforms a PRD into:

Module priority analysis with P0/P1/P2 grading and justification

Acceptance criteria in Given‑When‑Then format

Risk matrix (high/medium/low) with testing suggestions

Test checklist highlighting mandatory tests and missing requirements

Import methods

Method 1 – UI import (recommended)

Open TRAE → Settings ⚙ → Rules & Skills

Switch to Skills panel and click Create / + New Skill

Upload SKILL.md (or a .zip containing it)

Confirm after TRAE parses name, description, and commands

Enable the requirements-analysis entry

Global skill is available to all projects; project‑specific skill is stored under <project>/.trae/skills/requirements-analysis/SKILL.md.

Method 2 – Manual file placement

Create the following directory structure in the project root and place the skill file:

your-project/
└─ .trae/
   └─ skills/
      └─ requirements-analysis/
         └─ SKILL.md   ← paste the skill content here

Restart TRAE; the skill appears in the Skills panel.

Method 3 – Generate via TRAE Chat

In TRAE Chat, issue a command such as:

Help me create a Skill under .trae/skills named requirements-analysis with description: “From a tester’s perspective, break down a PRD into module priority, GWT acceptance criteria, risk matrix and test checklist.”

TRAE generates the SKILL.md automatically.

Usage scenarios

Scenario 1 – Full PRD analysis

In TRAE Chat or SOLO mode, input the PRD (or attach PRD.md) and invoke the requirements-analysis skill. The AI returns:

Module P0/P1/P2 priority table

GWT acceptance conditions (normal, abnormal, edge cases)

Risk matrix

P0 mandatory test checklist and identified documentation gaps

Save the output as 需求分析报告‑xxx.md for use as a test plan.

Scenario 2 – Impact assessment for requirement change

Provide the affected modules (e.g., “order and payment”) and the change description (e.g., “add combo discount stacking”). The AI marks which modules require regression testing and which can be omitted.

Scenario 3 – Test plan preparation

Use the P0 checklist generated by the skill, then add resource estimates and schedule dates to draft the initial test plan.

Technical value

Extracts core flows from PRDs, reducing manual reading.

Provides objective P0/P1/P2 priority classification.

Creates a structured risk matrix instead of ad‑hoc judgments.

Generates GWT‑formatted acceptance criteria ready for test case creation.

Lists missing requirements and clarification points, lowering communication overhead.
