SpecFlow Use

This skill helps you drive Grid Dynamics SpecFlow from a local workspace via SpecFlow MCP. Rosetta stays local; SpecFlow runs everything remotely. The skill loads project context from gain.json and guides the user through SpecFlow MCP tool usage.

SpecFlow MCP is the only user interface to SpecFlow: you order work and download outputs. You do not connect to or operate on the remote workspaces directly.

Quick Start

When the user mentions SpecFlow or works in a SpecFlow-enabled project:

Detect gain.json at the workspace root (and up to 2 parents). If missing, SpecFlow MCP will create it on the first tool call (together with specflow_session.json).
Load and summarize the project context.
Guide the user to the right phase — APPLY SKILL FILE references/specflow-mcp-tools.md.

Step 1: Detect gain.json

Check for gain.json at the current workspace root. If not found, check parent directories up to 2 levels. If still missing, tell the user this workspace is not yet initialized for SpecFlow — the first SpecFlow MCP tool call will create both gain.json and specflow_session.json.

Step 2: Parse and Display Context

When gain.json is found, present a compact summary:

## SpecFlow Project Context

**Description**: [gain.json.description]
**Services**: specflow — [gain.json.servicesDescription.specflow]
             rosetta  — [gain.json.servicesDescription.rosetta]
**Supported Coding Agents**: [gain.json.codingAgents]
**Versions**:
  - rosetta: [gain.json.versions.rosetta]
  - specflow:    [gain.json.versions.specflow]
**Vocabulary overrides** (if present in gain.json.vocabulary):
  - (See references/specflow-vocabulary.md for defaults.)

Version Compatibility Check

Compare gain.json.versions.rosetta with the current Rosetta version:
