Route Skill

Auto-routes tasks to the optimal profile + model combination based on bench-validated cost/capability data.

Routing table (bench-validated)

Triggers

Load this skill when the user asks:

• "which profile should I use for X"
• "should I use haiku for this"
• "route this task"
• "which model is best for"
• "how should I launch"

When triggered, run the classifier and print the routing recommendation:

~/.agents/venv/bin/python ~/.agents/skills/route/scripts/route.py "<task description>"

For in-session auto-routing (session start only): if the user's first message clearly signals a specific task type (≥2 keyword matches from the routing table), surface the routing suggestion briefly:

"This looks like a recall task — claude-recall (marvin + haiku) handles it at ~60% of this session's cost."

Only say this once, at the top of the session. Don't repeat it mid-session.

CLI usage

# After running install.sh:
route "what were the bench results?"      # classify + print
route "fix the bug" --launch              # classify + exec claude
route --recall --launch                   # explicit mode + launch
route --table                             # full routing table
route --aliases                           # print alias definitions
 
# Aliases (after install):
claude-recall       # marvin profile + Haiku
claude-research     # marvin profile + Haiku
claude-code         # lean profile + Sonnet
claude-arch         # marvin profile + Sonnet (default)
