Acceptance Criteria Verifier
When to Use
Use this skill to evaluate acceptance criteria quality. It's most valuable when:
- Reviewing criteria before development starts (catch issues early)
- Auditing existing criteria that have caused confusion or rework
- Ensuring criteria align with product standards
- Converting vague requirements into precise, testable statements
- Preparing criteria for team handoff to engineering
Input Format
The skill accepts acceptance criteria in multiple formats:
- Plain text: A list pasted directly into the message
- Markdown: Bullet points or numbered lists
- CSV/Excel: Uploaded spreadsheet files
- JSON: Structured data
- Mixed: Any combination of the above
Example inputs:
Given the user is logged in
When they navigate to the dashboard
Then they should see a list of their recent items
Or:
- Display loads within 2 seconds
- All product images render correctly
- User can filter by category
Evaluation Framework
Each acceptance criterion is evaluated against five dimensions of quality:
1. Clarity & Conciseness
- Is the language plain and unambiguous?
- Can all stakeholders interpret it the same way?
- Is it free of jargon or unexplained terms?
- Does it say exactly one thing, clearly?
Critical Issues: Ambiguous terms with multiple interpretations
Major Issues: Vague language; jargon without definition
Minor Issues: Wordy phrasing that could be tightened
2. Testability
- Can this criterion be objectively verified?
- Can it be mapped to one or more executable tests?
- Is there a clear pass/fail outcome?
- Would a QA engineer know exactly how to test it?
Critical Issues: No way to objectively verify the criterion
Major Issues: Testability requires subjective judgment; unclear success state
Minor Issues: Testable but the test path is not obvious
3. Outcome-Focused
- Does it describe the result, not the recipe?
- Does it focus on what the user experiences?
- Is it free of implementation details?
- Does it avoid prescribing the "how"?
Critical Issues: Criterion specifies technical implementation steps
Major Issues: Mixes outcome with technical approach
Minor Issues: Slight hints of implementation preference
4. Measurability
- Are expectations quantified where possible?
- Is there a definitive pass/fail threshold?
- Can success be objectively verified with data?
- Would different teams measure it the same way?
Critical Issues: No quantifiable metrics; purely subjective
Major Issues: Quantification is vague ("fast", "many", "some")
Minor Issues: Could be more precise (e.g., "300px" instead of "large")
5. Independence
- Does this criterion stand alone?
- Would it make sense without the others?
- Does it depend on other criteria to be meaningful?
- Can it be tested in isolation?
Critical Issues: Cannot be understood or tested without multiple other criteria
Major Issues: Requires significant context from other criteria
Minor Issues: Minor reference to another criterion for context
Output Format
The skill generates a structured JSON report:
{
"summary": {
"total_criteria": 5,
"passed": 2,
"failed": 3,
"critical_issues": 2,
"major_issues": 4,
"minor_issues": 1,
"overall_score": 65
},
"evaluations": [
{
"id": 1,
"criterion": "The page should load fast",
"status": "failed",
"issues": [
{
"dimension": "Measurability",
"severity": "critical",
"description": "The term 'fast' is not quantified. What constitutes fast? 1 second? 5 seconds?"
},
{
"dimension": "Testability",
"severity": "major",
"description": "Without a specific metric, QA cannot objectively verify this criterion."
}
],
"rewritten_option": "The page loads and displays all content within 2 seconds on a standard 4G connection"
}
],
"recommendations": [
"Add specific metrics to 3 criteria that currently use vague descriptors",
"Clarify technical dependencies between criteria 2 and 4",
"Consider breaking criterion 5 into two independent criteria"
]
}
How the Skill Works
Step 1: Parse Input
The skill first identifies and extracts all acceptance criteria from the input, regardless of format.
Step 2: Evaluate Against Five Dimensions
For each criterion, the skill evaluates it against:
- Clarity & Conciseness
- Testability
- Outcome-Focus
- Measurability
- Independence
Step 3: Identify Issues
The skill identifies specific issues for each criterion and assigns a severity level:
- Critical (~45% of score): Issues that prevent testing or create ambiguity
- Major (~35% of score): Issues that make the criterion harder to interpret or test
- Minor (~20% of score): Issues that could be improved but don't block delivery
Step 4: Calculate Scores
- Individual criterion score: (5 dimensions - issues) / 5 * 100
- Overall score: average of all criteria
- Pass threshold: 80+ is considered "good" quality
Step 5: Suggest Improvements
For each failed criterion, the skill proposes a rewritten version that addresses the identified issues.
Step 6: Generate Report
Output is structured JSON that can be:
- Reviewed directly in the chat
- Saved as a file for documentation
- Integrated into your workflow tools
- Used as the basis for discussions with your team
Bonus: Rewrite to User Story Format
After generating the report, you can ask the skill to convert the improved acceptance criteria into full user story format:
As a [user type],
I want to [action],
So that [benefit].
Acceptance Criteria:
- [Criterion 1]
- [Criterion 2]
...
This provides context for engineering teams and helps them understand the "why" behind each criterion.
Pro Tips
1. Start with high-level scenarios: If your input is very technical or vague, ask the skill to first help you write clear Given-When-Then scenarios.
2. Review one criterion at a time: For complex features, don't try to perfect all criteria at once. Review, implement, then move to the next.
3. Use this before planning: Run this evaluation during backlog refinement, not during sprint planning—catching issues early saves days of rework.
4. Involve your QA team: The testability dimension is often where QA engineers catch gaps. Use this report as a conversation starter.
5. Iterate with stakeholders: If the skill identifies ambiguity, use the report to drive a quick discussion with product and engineering about what you actually mean.
Example: From Vague to Good
Before (Failed):
"The user should be able to search easily and find results quickly"
Issues:
- Measurability (critical): "easily" and "quickly" are subjective
- Testability (major): No clear way to verify
- Clarity (minor): What is "search"? Database search, full-text, autocomplete?
After (Passed):
"The search results page displays at least 10 matching products within 1.5 seconds of the user typing their search query"
This version is measurable, testable, clear, and outcome-focused.
How to Trigger This Skill
Ask your assistant to verify acceptance criteria by saying things like:
- "Review these acceptance criteria and tell me if they're good"
- "Check if these ACs will cause problems during testing"
- "Audit our user story criteria against quality standards"
- "Are these acceptance criteria testable?"
- "Rewrite these acceptance criteria to be clearer"
- "Do we have enough detail in these ACs for the team to start work?"
This skill will automatically and generate a structured evaluation report.
