Changes

• scripts/route_policy.schema.json is a verbatim copy of Lemonade's route_policy.schema.json. validate.py takes its allowed keys, condition types, classifier types and value checks from it instead of hard-coded lists. A small set of checks the schema can't express stays hand-written: ECMAScript regex, cross-references, and empty reference_phrases entries.
• min_total_chars / max_total_chars are documented in SKILL.md and reference.md, and there's a new eval (long-conversation-router).
• Server-side check: step 8b now starts with POST /api/v1/routing/validate (v11.6.0+), which runs the target server's own parser on the policy without registering it.

Verification

• The bundled schema is identical to Lemonade main and to v2026.43.3.
• All 29 policies in Lemonade's conformance tests and its router examples pass. The old validator rejected conditions_total_char_bounds.
• 40 policies the server rejects are still rejected.

Closed: this is a vendored copy

skills/lemonade-router-builder is a mirror of a product repo, not source. The nightly federate-skills run re-imports the folder wholesale, so a change merged here is deleted the next time the source repo moves. Please make it upstream instead:

Vendored copy	Edit it here	Land it on
skills/lemonade-router-builder	lemonade-sdk/skills/skills/lemonade-router-builder	main

Once it is on that branch there, this catalog picks it up on its own (nightly, or by dispatching
federate-skills). See CONTRIBUTING.md.

Maintainers: if the change has to land here (retiring a federated skill, forcing a re-import), add the federation-override label and reopen.
