Hermes Code Bridge Multi-Agent Router
System Blueprint Overview: The Hermes Code Bridge Multi-Agent Router workflow is an elite agentic system designed to automate general operations. By leveraging autonomous AI agents, it significantly reduces manual overhead, saving approximately 20-30 hours per week while ensuring high-fidelity output and operational scalability.
Hermes Agent v0.13 acts as a central routing layer that accepts task descriptions via Telegram, CLI, or webhook, then assigns each coding task to the best-suited agent among Claude Code, OpenAI Codex CLI, Gemini CLI, or OpenCode. The agentic reasoning step happens inside Hermes when it evaluates each task against four criteria: codebase language (Python tasks go to Codex, TypeScript to Claude Code), task complexity (simple refactors to OpenCode, multi-file features to Claude Code), model availability (Gemini CLI for Google Cloud-integrated projects), and developer preference overrides. This is not simple round-robin load balancing — Hermes maintains a skill registry that tracks which agent performed best on which task type historically and adjusts routing weights accordingly. A unified MCP bridge standardizes the interface to all four coding agents, so adding a fifth agent requires one config entry. Developers using this multi-agent router report 20-30 hours saved per week through parallel task execution and agent specialization.
BUSINESS PROBLEM
A development team using multiple AI coding tools faces a coordination problem: Claude Code excels at TypeScript and full-stack work, Codex handles Python and data pipelines best, Gemini CLI is optimized for Google Cloud deployments, and OpenCode offers the widest model selection for experimental work. Without a router, team members manually choose which tool to use for each task, context-switch between terminals, and duplicate project context files across tools. McKinsey research found that AI tools could add $2.6-$4.4 trillion annually to the global economy, but only if adoption is structured rather than ad-hoc (Source: McKinsey, 2024). Manual tool selection costs each developer 30-60 minutes daily in decision fatigue and setup overhead. For a team of five senior developers at $100/hour, that is $62,500-$125,000 per year lost to inefficient tool routing. The multi-agent router eliminates this by treating the tool fleet as a unified resource pool with automatic assignment.
WHO BENEFITS
Technical team leads managing 4-8 developers who each use different AI coding tools and need to standardize without forcing a single tool on everyone. This workflow lets each developer keep their preferred tool while the router ensures optimal task assignment. Freelance platform engineers who maintain codebases across Python, TypeScript, Go, and Rust and need the best model for each language without installing four separate tool configurations per project. DevOps engineers managing infrastructure-as-code (Terraform/Pulumi) alongside application code who want Gemini CLI for GCP operations and Claude Code for app logic, routed through one Telegram interface.
HOW IT WORKS
- Task Intake: Hermes Agent receives a task via Telegram message, CLI input, or incoming webhook. Input: natural language task description (e.g., Refactor the auth module to use JWT and add unit tests). Output: structured task object with language, scope, and urgency fields.
- Codebase Analysis (Agentic Reasoning): Hermes reads the project's CLAUDE.md, AGENTS.md, and package.json (or equivalent) to determine the primary language, framework, and tool conventions. It evaluates task complexity by counting file references and keywords like refactor or migration. Output: routing recommendation with confidence score.
- Agent Assignment: Hermes consults its routing table — a configurable YAML map that assigns preferred agents per language, framework, and task type. Example: Python+FastAPI goes to Codex, Next.js+TypeScript goes to Claude Code, GCP deployment goes to Gemini CLI, experimental R&D goes to OpenCode. Output: selected agent ID and connection parameters.
- MCP Bridge Execution: Hermes opens an MCP session with the selected agent. The agent receives the task with project context, workspace files, and success criteria. Output: execution logs streamed back to Hermes in real time.
- Parallel Dispatch (Optional): If the task has independent sub-tasks, Hermes splits them and dispatches to multiple agents simultaneously. Claude Code handles API routes while Codex handles data migrations. Output: merged result with per-agent attribution.
- Output Collection and Validation: Each agent returns its results (diffs, test outputs, commit hashes) through the MCP bridge. Hermes validates that all required files were changed and tests pass. Output: consolidated summary.
- Human Review Gate: Hermes sends the consolidated result to Telegram or Slack. The developer reviews and responds with /approve, /reject, or /revise. Rejected tasks return to step 3 with a different agent. Output: final approval token.
- Routing Table Update: If the developer manually overrides a routing decision, Hermes records the override and adjusts future routing weights for similar tasks. Output: updated routing table with recalculated confidence scores.
TOOL INTEGRATION
Hermes Agent v0.13: The central router. Runs on a VPS or local server. Connects to all four coding agents via MCP client mode. Configure routing rules in config.yaml under a custom agent_routing section. Rate limit: depends on LLM provider. Gotcha: Hermes's MCP client mode loads all configured MCP servers at startup, but if any server fails to connect (e.g., Codex is offline), Hermes blocks startup. Use the tools.include filter to make servers optional.
Claude Code: Primary agent for TypeScript, full-stack, and complex multi-file refactors. Installed via npm. API key from console.anthropic.com. Rate limit: 80 RPM on API tier. Permission: project filesystem. Gotcha: Claude Code reads CLAUDE.md at startup — if your project does not have one, the agent will not know your conventions, resulting in style-inconsistent code.
OpenAI Codex CLI: Primary agent for Python, data pipelines, and testing. Installed via npm globally. Authentication uses ChatGPT plan or API key. Rate limit: included in ChatGPT subscription for Plus/Pro users. Permission: OS-level sandbox (Bubblewrap on Linux). Gotcha: Codex uses AGENTS.md, not CLAUDE.md — you must maintain both files if you route between Claude Code and Codex.
Gemini CLI: Primary agent for Google Cloud operations and API integrations. Installed via npm globally. Requires Google Cloud project with billing enabled. Rate limit: 60 RPM on free tier, 1200 RPM on paid. Gotcha: Gemini CLI's MCP support is still experimental as of May 2026 — you may need to use the HTTP Request node in n8n as a fallback bridge.
OpenCode: Primary agent for experimental work and model-agnostic tasks. Installed via Homebrew or npm. Connects to 75+ model providers. Rate limit: none (uses your own API keys). Gotcha: OpenCode supports both AGENTS.md and CLAUDE.md conventions, but reads them in a different priority order than Claude Code — test your instruction files.
ROI METRICS
- Tool selection overhead: 30-60 min/day per developer choosing and configuring the right tool → under 2 min/day with automatic routing.
- Parallel task execution: 1 task at a time per developer → 3-4 tasks in parallel via multi-agent dispatch, measurable in week 1.
- Context file duplication: 15-20 min per project per tool maintaining CLAUDE.md, AGENTS.md, and config files → one set of instruction files in the repo root, read by all agents.
- Task completion time for multi-language projects: 8-12 hours per feature spanning Python backend + TypeScript frontend → 3-5 hours with parallel agent dispatch.
- Cost at $100/hr for team of 5: $4,000/week in tool-selection overhead → $200/week in API costs across 4 agents.
CAVEATS
- MCP server cascade failure: If Hermes's MCP client loses connection to one agent, it may hang waiting for a response rather than failing over. Configure timeout of 30 seconds per server in config.yaml.
- Inconsistent output formats: Each agent returns diffs in different formats. Codex returns unified diffs, Claude Code returns git-formatted patches, Gemini CLI returns inline edits. Hermes does not normalize these — your review step must handle multiple formats.
- API key sprawl: Four agents means four API keys (or subscriptions). A misconfigured routing rule could route high-volume tasks to an expensive agent. Set max_cost_per_task in the routing table.
- This workflow does NOT handle real-time collaborative editing or simultaneous file writes to the same file — agents work on isolated copies and Hermes merges with git.
