Meta Router

Entry point for all routing decisions. Classifies intent and delegates to appropriate unified router.

Routing Logic

Weight Distribution

Factor	Weight	Description
Keyword Match	40%	Scan user intent for trigger keywords
Context Analysis	30%	Current project type, recent operations
History Pattern	20%	Recent skill usage patterns
Explicit Request	10%	User directly names skill/category

Direct Shortcuts (Bypass Routing)

For known skills, bypass routing entirely:

# Skill shortcuts
/ultrawork     -> ~/.claude/skills/ultrawork/SKILL.md
/learn         -> ~/.claude/skills/learn/SKILL.md
/lambda        -> ~/.claude/skills/lambda-skill/SKILL.md
/obsidian      -> ~/.claude/skills/obsidian/SKILL.md
/git           -> ~/.claude/skills/git-master/SKILL.md

# Agent shortcuts
oracle         -> oracle agent (complex debugging)
explore        -> explore agent (quick search)
sisyphus       -> sisyphus-junior agent (focused execution)

Complexity Assessment

def assess_complexity(task):
    score = (
        0.30 * files_affected(task) +
        0.25 * domains_involved(task) +
        0.25 * steps_required(task) +
        0.20 * research_needed(task)
    )
    return score

# Routing thresholds
if score > 0.7:
    route_to("delegate-router")  # Complex delegation
elif score > 0.4:
    route_to("think-router")     # Analysis needed
else:
    route_to("build-router")     # Direct execution

Usage

When this router activates:

1. Announce: "Routing to [router] for [reason]"
2. Load the unified router
3. The router further refines to specific skill/agent
