main-router

main-router is a skill for Claude Code, Codex from VCnoC/Claude-Code-Zen-mcp-Skill-Work. It costs 93 tokens per session (12,790 once invoked), scanned A, original, Apache-2.0.

A routing tool that reads a request and sends it to the most suitable specialized skill or analysis tool.

In plain words
What is it for?
Use it to classify requests, select one or more skills, coordinate them in order or in parallel, and apply project rules such as CLAUDE.md files.
Why use it?
It removes the need to choose the right workflow yourself when a task could involve code review, planning, documentation, deep analysis, or general questions.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/vc/.claude/CLAUDE.md.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

main-router scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Main Router - Intelligent Skill Routing Scheduler

Overview

This skill serves as the central intelligence hub that analyzes user requests and automatically routes them to the most appropriate skill(s) for execution. It acts as a smart dispatcher, understanding user intent and orchestrating the right tools for the job.

Core Capabilities:

  • Standards-based routing (follows CLAUDE.md)
  • Intent analysis and classification
  • Skill matching and selection
  • Multi-skill orchestration (sequential or parallel)
  • Conflict resolution and disambiguation
  • Automatic routing without user intervention
  • Full automation mode support (router makes decisions autonomously)

Division of Responsibilities:

  • Main Router: Analyzes request → Reads standards → Determines skill(s) → Invokes skill(s) → Coordinates execution
  • Specialized Skills: Execute their specific tasks when invoked by router

Standards Compliance:

  • MUST read global and project CLAUDE.md before routing
  • Apply standards hierarchy: Global CLAUDE.md > Project CLAUDE.md
  • All routing decisions must align with documented rules and workflows

Active Task Monitoring (CRITICAL - Router Must Not Be Lazy):

Main Router MUST actively monitor the entire task lifecycle and proactively invoke appropriate skills at each stage. Do NOT skip skill invocations to save time - proper skill usage ensures quality and compliance.

Mandatory Workflow Rules:

  1. Planning Phase:

    • When user requests "make a plan" / "generate plan.md" / "plan tasks"
    • MUST use plan-down skill (not Main Claude direct planning)
    • Rationale: plan-down provides multi-model validation and structured decomposition
  2. Code Generation → Quality Check Cycle:

    • After Main Claude completes ANY code generation/modification
    • MUST invoke codex-code-reviewer to validate quality
    • Rationale: Ensures 5-dimension quality check (quality, security, performance, architecture, docs)
  3. Test Code Generation Workflow:

    • When Main Claude needs test code
    • Step 1: MUST invoke simple-gemini to generate test files
    • Step 2: MUST invoke codex-code-reviewer to validate generated tests
    • Step 3: Return validated tests to Main Claude for execution
    • Rationale: Ensures test quality before execution

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
