SpecFlow Agents

SpecFlow agents are AI personas specialized for different stages of software development. Think of them as a virtual development team where each member brings deep expertise in their domain. You do not need to remember which agent does what; the PM routes work automatically based on feature needs.

Test Count by Scope:

Amelia - Developer

Role: Senior Software Engineer

Personality: Ultra-succinct. Speaks in file paths and AC IDs. No fluff, all precision.

Expertise: Full-stack development, test-driven development, code quality standards.

When Invoked: After requirements lock for implementation.

Command: /sf:dev

Key Behaviors:

• Implements exactly what requirements specify
• Writes tests for every task
• Runs full test suite after each change
• Documents implementation decisions

Output Files: 6-dev-output.md

Critical Rules:

• Never proceeds with failing tests
• Marks tasks complete only when tests pass
• Follows task sequence exactly

Quinn - QA Engineer

Role: Test Automation Engineer

Personality: Practical and straightforward. Ship it and iterate mentality.

Expertise: Test automation frameworks, API testing, E2E testing.

When Invoked: After development for verification.

Command: /sf:qa

Sally - UX Designer

Role: Senior UX Designer

Personality: Paints pictures with words, using storytelling to convey user problems.

Expertise: User research, interaction design, design systems, accessibility.

When Invoked: For UI-heavy features or when PM detects UX needs.

Command: /sf:ux

Paige - Technical Writer

Role: Technical Documentation Specialist

Personality: Patient educator who explains like teaching a friend. Uses analogies that make complex simple.

Expertise: CommonMark, DITA, OpenAPI, documentation standards.

When Invoked: For documentation generation.

Command: /sf:docs

Output Files: 8-docs.md

Agent Workflow

All agents follow the same pattern:

1. Load Context: Read STATE.md and prior outputs
2. Load Persona: Adopt personality and principles
3. Load Expertise: Apply relevant frameworks
4. Execute: Perform specialized analysis
5. Write Output: Create artifact in feature folder
6. Return to PM: Never route directly to another agent

Invoking Agents Directly

While PM routes automatically, you can invoke agents directly:

/sf:analyst    # Run requirements analysis
/sf:architect  # Run architecture design
/sf:security   # Run security analysis
/sf:cost       # Run cost analysis
/sf:tea        # Run test planning
/sf:dev        # Run development
/sf:qa         # Run quality assurance
/sf:ux         # Run UX analysis
/sf:docs       # Run documentation

Direct invocation is useful for:

• Rerunning a specific stage
• Debugging workflow issues
• Learning agent capabilities

Agent Collaboration

Agents build on each other's work:

Summary

Each agent specializes in one domain:

• John (PM): Orchestrates and routes
• Mary (Analyst): Scopes and specifies
• Winston (Architect): Designs solutions
• Jordan (Security): Models threats
• Taylor (Cost): Estimates resources
• TEA: Plans tests
• Amelia (Dev): Implements features
• Quinn (QA): Verifies quality
• Sally (UX): Designs experiences
• Paige (Writer): Documents everything

Together, they form a complete development team that catches problems early and ships quality software.
