What it does

Specflow Use is an agent skill from griddynamics/rosetta. To connect Rosetta with Grid Dynamics SpecFlow MCP; only when SpecFlow is mentioned and the MCP is installed.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `README.md`, `references/specflow-mcp-tools.md` and `references/specflow-schema.md`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: An instruction layer for AI coding agent. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/specflow-use”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Detect gain.json
  2. Parse and Display Context
  3. Guide the User Journey
  4. Consolidate Review Feedback

What it can do on your machine

Read from SKILL.md and the folder at commit 5441232. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Specflow Use loads about 780 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 324 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~780
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

  1. 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).
  2. Load and summarize the project context.
  3. 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:

  • Minor difference: warn and continue.
  • Major difference: alert the user about potential incompatibilities.

Step 3: Guide the User Journey

APPLY SKILL FILE references/specflow-mcp-tools.md to route the user to the correct phase (pregeneration, generation, or post-run).

Step 4: Consolidate Review Feedback

When SpecFlow returns a review report and the user wants to fix their specs before another iteration, delegate to Rosetta core:

  • Skill: skills/requirements-authoring
  • Workflow: workflows/requirements-authoring-flow.md

That skill handles iterative requirement updates with explicit user approval — matching the "consolidate the review report into updated specs" loop.

Reference Files

Read as needed:

  • APPLY SKILL FILE references/specflow-mcp-tools.md — Phase routing and post-run skill bootstrap.
  • READ SKILL FILE references/specflow-vocabulary.md — Status values and checkpoint gates users encounter in responses.
  • READ SKILL FILE references/specflow-schema.md — Session files, version channels, and status enum quick lookup.
