Router

router

A meta-skill that helps you navigate your own skill library. It tracks which skills you actually invoke (via a PostToolUse hook into a local SQLite DB), ranks candidate skills for a request, and chains skills into named, declarative workflows the way superpowers chains brainstorming → planning → execution.

Variables

• DB_PATH: <skill-dir>/data/usage.db by default — the script resolves its own install location via __file__, so the DB lives wherever the skill is installed. Override with the ROUTER_DB env var.
• CLI: python3 <skill-dir>/scripts/router.py <subcommand> (stdlib only)
• WORKFLOWS_DIR: <skill-dir>/workflows/ — resolved at runtime; one *.md per workflow.
• HOOK_SETTINGS: $HOME/.claude/settings.json by default; override with --settings on install-hook.

The default install location is $HOME/.claude/skills/router/ (see README). If you install elsewhere, swap that path into the commands above.

How It Works

A PostToolUse hook on the Skill tool logs every skill invocation (name, args, session, timestamp) into SQLite. stats aggregates that log; pick blends lexical relevance + usage frequency + recency into a shortlist that you choose from; workflows are declarative markdown files the agent walks step by step, announcing each handoff.

install-hook embeds the absolute path to the script at install time, so the hook works no matter where the skill is installed.

Arguments

Invoke as /router <command> [arguments]. Parse the text after /router: the first whitespace-delimited token is the command; everything after it is that command's arguments (free text and/or --flags). --flags pass straight through to the CLI.

Invocation	Command	Arguments
/router stats [--days N] [--limit N]	stats	optional window + cap
/router pick <request>	pick	free-text task description (required)
/router run <workflow>	run	a workflow name from /router workflows
/router workflows	workflows	none
/router setup	setup	none

Defaults & aliases (apply before dispatching):

• No command but free text follows (e.g. /router fix a flaky test) → treat the whole thing as pick <that text>.
• No command and no text → show this Arguments table and stop.
• Aliases: top / most-used / usage → stats; recommend / choose / which → pick; list → workflows.
• Unrecognized command → show the table and ask which they meant; do not guess.

Once the command and arguments are parsed, read the matching cookbook file, then execute it with those arguments.

Commands

Command	Purpose
/router setup	Install the usage hook + initialize the SQLite DB
/router stats	List your most-used skills (all-time or a recent window)
/router pick <request>	Recommend the best-fit skills for a request; you choose
/router workflows	List defined multi-skill workflows
/router run <workflow>	Walk a named workflow step by step, with handoffs

Cookbook

Each command has a detailed step-by-step guide. Read the relevant cookbook file before executing a command.

Command	Cookbook	Use When
setup	cookbook/setup.md	First-time install, or the hook/DB is missing or broken
stats	cookbook/stats.md	User wants most-used / top skills or usage numbers
pick	cookbook/pick.md	User wants to choose a skill for a task, or "what should I use"
workflows	cookbook/workflows.md	User wants to list, run, or define a back-to-back workflow

When a user invokes a /router command, read the matching cookbook file first, then execute the steps.

Notes

• The hook records skills invoked through the Skill tool in the main session, which includes skills you trigger with /slash (the agent routes those through the Skill tool). Counting starts when setup runs — there is no backfill.
• Plugin skills (e.g. superpowers:brainstorming) are tracked by name even though their SKILL.md lives in the plugin cache rather than the scanned catalog roots; combine the file catalog with the live in-context skill list when picking.
