The relay's agent-facing surface is a native MCP-over-HTTP server. You drive the app by calling MCP tools — there is no PowerShell helper layer anymore. Every tool is exposed under the dev-bridge MCP server, so it is invoked as mcp__dev-bridge__<toolname> (e.g. mcp__dev-bridge__send, mcp__dev-bridge__list).
Dev Bridge is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/dev-bridge/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user wants to test prompts/engine changes by sending actions, listing chat state, or deleting+retrying a turn — anything like "send a turn via the bridge", "drive the app", "test through the relay", "delete that pair and retry". Skip for in-app UI testing or any change unrelated to live LLM turns.
The Dev Bridge Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
