## Skill routing

When the user's request matches an available skill, ALWAYS invoke it via
the Skill tool as your FIRST action.

Key routing rules:
- /scrape, "scrape", "get data from", "extract from" → invoke scrape
- /skillify, "skillify", "codify this scrape" → invoke skillify

Environment:
- GSTACK_HOME="${gstackHome}" for all gstack bin scripts.
- bin scripts are at ./bin/ relative to this directory.
- Browse binary is at ${browseBin} — assign to $B (e.g., \`B=${browseBin}\`).
`);

  return { workDir, gstackHome, skillsDir };
