Speckit Specify Skill
User Provided Context
{{user_provided_context}}
You MUST consider the User Provided Context before proceeding (if not empty).
Outline
The text the user typed after speckit-specify in the triggering message is the feature description. Assume you always have it available in this conversation even if {{user_provided_context}} appears literally below. Do not ask the user to repeat it unless they provided an empty skill.
Given that feature description, do this:
Generate a concise short name (2-4 words) for the branch:
- Analyze the feature description and extract the most meaningful keywords
- Create a 2-4 word short name that captures the essence of the feature
- Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
- Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
- Keep it concise but descriptive enough to understand the feature at a glance
- Examples:
- "I want to add user authentication" → "user-auth"
- "Implement OAuth2 integration for the API" → "oauth2-api-integration"
- "Create a dashboard for analytics" → "analytics-dashboard"
- "Fix payment processing timeout bug" → "fix-payment-timeout"
Check for existing branches before creating new one:
a. First, fetch all remote branches to ensure we have the latest information:
git fetch --all --prune
b. Find the highest feature number across all sources for the short-name:
- Remote branches:
git ls-remote --heads origin | grep -E 'refs/heads/[0-9]+-<short-name>$'
- Local branches:
git branch | grep -E '^[* ]*[0-9]+-<short-name>$'
- Specs directories: Check for directories matching
specs/[0-9]+-<short-name>
c. Determine the next available number:
- Extract all numbers from all three sources
- Find the highest number N
- Use N+1 for the new branch number
d. Run the script .specify/scripts/bash/create-new-feature.sh --json "{{user_provided_context}}" with the calculated number and short-name:
- Pass
--number N+1 and --short-name "your-short-name" along with the feature description
- Bash example:
.specify/scripts/bash/create-new-feature.sh --json "{{user_provided_context}}" --json --number 5 --short-name "user-auth" "Add user authentication"
- PowerShell example:
.specify/scripts/bash/create-new-feature.sh --json "{{user_provided_context}}" -Json -Number 5 -ShortName "user-auth" "Add user authentication"
IMPORTANT:
- Check all three sources (remote branches, local branches, specs directories) to find the highest number
- Only match branches/directories with the exact short-name pattern
- If no existing branches/directories found with this short-name, start with number 1
- You must only ever run this script once per feature
- The JSON is provided in the terminal as output - always refer to it to get the actual content you're looking for
- The JSON output will contain BRANCH_NAME and SPEC_FILE paths
- For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'''m Groot' (or double-quote if possible: "I'm Groot")
Load .specify/templates/spec-template.md to understand required sections.
Follow this execution flow:
- Parse user description from Input
If empty: ERROR "No feature description provided"
- Extract key concepts from description
Identify: actors, actions, data, constraints
- For unclear aspects:
- Make informed guesses based on context and industry standards
- Only mark with [NEEDS CLARIFICATION: specific question] if:
- The choice significantly impacts feature scope or user experience
- Multiple reasonable interpretations exist with different implications
- No reasonable default exists
- LIMIT: Maximum 3 [NEEDS CLARIFICATION] markers total
- Prioritize clarifications by impact: scope > security/privacy > user experience > technical details
- Fill User Scenarios & Testing section
If no clear user flow: ERROR "Cannot determine user scenarios"
- Generate Functional Requirements
Each requirement must be testable
Use reasonable defaults for unspecified details (document assumptions in Assumptions section)
- Define Success Criteria
Create measurable, technology-agnostic outcomes
Include both quantitative metrics (time, performance, volume) and qualitative measures (user satisfaction, task completion)
Each criterion must be verifiable without implementation details
- Identify Key Entities (if data involved)
- Return: SUCCESS (spec ready for planning)
Write the specification to SPEC_FILE using the template structure, replacing placeholders with concrete details derived from the feature description (arguments) while preserving section order and headings.
Specification Quality Validation: After writing the initial spec, validate it against quality criteria:
a. Create Spec Quality Checklist: Generate a checklist file at FEATURE_DIR/checklists/requirements.md using the checklist template structure with these validation items:
# Specification Quality Checklist: [FEATURE NAME]
**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: [DATE]
**Feature**: [Link to spec.md]
## Content Quality
- [ ] No implementation details (languages, frameworks, APIs)
- [ ] Focused on user value and business needs
- [ ] Written for non-technical stakeholders
- [ ] All mandatory sections completed
## Requirement Completeness
- [ ] No [NEEDS CLARIFICATION] markers remain
- [ ] Requirements are testable and unambiguous
- [ ] Success criteria are measurable
- [ ] Success criteria are technology-agnostic (no implementation details)
- [ ] All acceptance scenarios are defined
- [ ] Edge cases are identified
- [ ] Scope is clearly bounded
- [ ] Dependencies and assumptions identified
## Feature Readiness
- [ ] All functional requirements have clear acceptance criteria
- [ ] User scenarios cover primary flows
- [ ] Feature meets measurable outcomes defined in Success Criteria
- [ ] No implementation details leak into specification
## Notes
- Items marked incomplete require spec updates before `speckit-clarify` or `speckit-plan`
b. Run Validation Check: Review the spec against each checklist item:
- For each item, determine if it passes or fails
- Document specific issues found (quote relevant spec sections)
c. Handle Validation Results:
If all items pass: Mark checklist complete and proceed to step 6
If items fail (excluding [NEEDS CLARIFICATION]):
- List the failing items and specific issues
- Update the spec to address each issue
- Re-run validation until all items pass (max 3 iterations)
- If still failing after 3 iterations, document remaining issues in checklist notes and warn user
If [NEEDS CLARIFICATION] markers remain:
Extract all [NEEDS CLARIFICATION: ...] markers from the spec
LIMIT CHECK: If more than 3 markers exist, keep only the 3 most critical (by scope/security/UX impact) and make informed guesses for the rest
For each clarification needed (max 3), present options to user in this format:
## Question [N]: [Topic]
**Context**: [Quote relevant spec section]
**What we need to know**: [Specific question from NEEDS CLARIFICATION marker]
**Suggested Answers**:
| Option | Answer | Implications |
|--------|--------|--------------|
| A | [First suggested answer] | [What this means for the feature] |
| B | [Second suggested answer] | [What this means for the feature] |
| C | [Third suggested answer] | [What this means for the feature] |
| Custom | Provide your own answer | [Explain how to provide custom input] |
**Your choice**: _[Wait for user response]_
CRITICAL - Table Formatting: Ensure markdown tables are properly formatted:
- Use consistent spacing with pipes aligned
- Each cell should have spaces around content:
| Content | not |Content|
- Header separator must have at least 3 dashes:
|--------|
- Test that the table renders correctly in markdown preview
Number questions sequentially (Q1, Q2, Q3 - max 3 total)
Present all questions together before waiting for responses
Wait for user to respond with their choices for all questions (e.g., "Q1: A, Q2: Custom - [details], Q3: B")
Update the spec by replacing each [NEEDS CLARIFICATION] marker with the user's selected or provided answer
Re-run validation after all clarifications are resolved
d. Update Checklist: After each validation iteration, update the checklist file with current pass/fail status
Report completion with branch name, spec file path, checklist results, and readiness for the next phase (speckit-clarify or speckit-plan).
NOTE: The script creates and checks out the new branch and initializes the spec file before writing.
General Guidelines
Quick Guidelines
- Focus on WHAT users need and WHY.
- Avoid HOW to implement (no tech stack, APIs, code structure).
- Written for business stakeholders, not developers.
- DO NOT create any checklists that are embedded in the spec. That will be a separate skill.
Section Requirements
- Mandatory sections: Must be completed for every feature
- Optional sections: Include only when relevant to the feature
- When a section doesn't apply, remove it entirely (don't leave as "N/A")
For AI Generation
When creating this spec from a user prompt:
- Make informed guesses: Use context, industry standards, and common patterns to fill gaps
- Document assumptions: Record reasonable defaults in the Assumptions section
- Limit clarifications: Maximum 3 [NEEDS CLARIFICATION] markers - use only for critical decisions that:
- Significantly impact feature scope or user experience
- Have multiple reasonable interpretations with different implications
- Lack any reasonable default
- Prioritize clarifications: scope > security/privacy > user experience > technical details
- Think like a tester: Every vague requirement should fail the "testable and unambiguous" checklist item
- Common areas needing clarification (only if no reasonable default exists):
- Feature scope and boundaries (include/exclude specific use cases)
- User types and permissions (if multiple conflicting interpretations possible)
- Security/compliance requirements (when legally/financially significant)
Examples of reasonable defaults (don't ask about these):
- Data retention: Industry-standard practices for the domain
- Performance targets: Standard web/mobile app expectations unless specified
- Error handling: User-friendly messages with appropriate fallbacks
- Authentication method: Standard session-based or OAuth2 for web apps
- Integration patterns: RESTful APIs unless specified otherwise
Success Criteria Guidelines
Success criteria must be:
- Measurable: Include specific metrics (time, percentage, count, rate)
- Technology-agnostic: No mention of frameworks, languages, databases, or tools
- User-focused: Describe outcomes from user/business perspective, not system internals
- Verifiable: Can be tested/validated without knowing implementation details
Good examples:
- "Users can complete checkout in under 3 minutes"
- "System supports 10,000 concurrent users"
- "95% of searches return results in under 1 second"
- "Task completion rate improves by 40%"
Bad examples (implementation-focused):
- "API response time is under 200ms" (too technical, use "Users see results instantly")
- "Database can handle 1000 TPS" (implementation detail, use user-facing metric)
- "React components render efficiently" (framework-specific)
- "Redis cache hit rate above 80%" (technology-specific)
