Skill Stack Router

You have 50+ skills installed and your agent still picks the wrong one half the time. It uses the coding skill for a writing task. It reaches for a marketing persona when it needs a research tool. It tries three skills before finding the right one — burning credits and context window on every wrong guess. The problem isn't missing skills. It's missing routing. Your agent doesn't know which skill is best for which job.

Skill Stack Router adds a zero-config routing layer for skill-heavy workspaces. Before your agent starts a task, the router identifies the real job, shortlists the best installed skills and personas using a weighted scorecard, picks the winner, and surfaces capability gaps honestly instead of pretending the right skill exists. It asks only the clarifying questions that actually change the route — no unnecessary interruptions. One install, and your agent stops thrashing.

What's Included

• Complete SKILL.md with routing workflow and decision logic
• Weighted scorecard for skill selection (relevance, specificity, reliability, recency)
• Tie-break rules when multiple skills score equally
• File-format trigger map — route by deliverable type (code, docs, data, media)
• Clarifying-question bank — minimal questions that change the route, nothing else
• Capability-gap detection template — honest "you don't have a skill for this" output
• Example routing decisions showing the scorecard in action
• 60-second install path with first-install verification

Why This is Better

• Zero config — works immediately with whatever skills you have installed
• Weighted scorecard beats random skill selection or naive keyword matching
• Detects capability gaps instead of forcing a bad-fit skill onto the task
• Minimal clarifying questions — only asks when the answer changes the route
• Built from operating a workspace with 150+ skills where wrong-skill thrash was a daily problem
• Pairs naturally with Model Choice Router — right skill AND right model for every task
