How do I install the Si skill?

Run npx skillmds@latest add frankxai/si in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Si skill do?

Superintelligence router — composes /superintelligence reasoning with swarm execution only when verb intent demands it. Defaults to reasoning-only to prevent runaway swarm cost. Triggers — /si , "think deeply about X", "analyze X with full depth", or any ask requiring multi-perspective + first-principles + contrarian framing. It is listed under Coding & Dev Tools on SkillMD.

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Si?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

/si — Superintelligence Router

Route ANY ask through this 3-step protocol:

Step 1 — Classify intent

Parse $ARGUMENTS for verb. Match against these classes:

Execution verbs (route to: reasoning + swarm)

build, ship, deploy, fix, elevate, create, refactor, migrate, scaffold, wire, sync, audit-and-fix, redesign, rebuild, generate, render

Reasoning verbs (route to: reasoning only)

think, plan, compare, analyze, should, what if, why, evaluate, audit, research, explore, decide

Bare topic (no verb)

Route to: reasoning only, then ASK "Should I dispatch a swarm to execute this?"

Step 2 — Invoke /superintelligence

Always. Pass $ARGUMENTS as the topic. Capture the reasoning output.

Cost: ~5K input + ~3K output tokens, ~$0.05. Cheap enough to always run.

Step 3 — Route based on Step 1 classification

If execution intent

After /superintelligence returns, dispatch the appropriate swarm:

"build / scaffold / create / generate" → BUILD lane (e.g., /v BUILD or feature-dev or frankx-website-builder agent)
"deploy / ship / sync" → DEPLOY lane (e.g., /v DEPLOY)
"fix / refactor / migrate" → FIX lane
"elevate / redesign / rebuild" → ELEVATE lane (e.g., /v ELEVATE)
"audit-and-fix" → /v ELEVATE
Multi-domain ambiguity → ask which lane

If reasoning intent

Return /superintelligence verdict directly. Surface a one-line "Want to execute this?" footer.

If bare topic

Return /superintelligence verdict. Surface explicit "Should I dispatch a swarm to execute this?" question with 3 options (yes-execute / no-thinking-only / scope-first).

Cost discipline

Never auto-dispatch a swarm on a bare-topic ask
Never skip /superintelligence on execution intent (the framing is the value)
Per-invocation cost budget: ~~$0.05 reasoning + variable swarm cost (~~$0.30-$3 per agent × N agents)
Compare to: a pure /v ELEVATE run is ~$1.50-$5 — /si adds $0.05 of reasoning at the front for better orchestration

Anti-patterns

Auto-dispatching swarm on every /si call (burns money on tasks that needed only thinking)
Skipping /superintelligence on execution (loses multi-perspective framing)
Treating /si as an alias for /superintelligence (it's a router, not a duplicate)
