"""Generator: TypeScript board agents + companion skills from per-agent JSON data files.

Reads every ``scripts/typescript_data/agents/*.json`` (one file per agent) and emits, in
the Java-board static-review house style:

  agents/typescript/<id>/AGENT.md
  agents/typescript/<id>/metadata.json
  agents/typescript/<id>/harnesses/{codex.toml,copilot.agent.md,claude-code.agent.md,
                                cursor.agent.md,gemini.agent.md,kiro-ide.agent.md,
                                kiro-cli.agent.json}
  agents/typescript/<id>/README.md            (maestro only)
  skills/typescript/<skill-id>/SKILL.md
  skills/typescript/<skill-id>/metadata.json
  skills/typescript/<skill-id>/references/*.md

The judgment lives in the per-agent data files; this script only renders structure so
the whole board stays consistent and reproducible (behaviour changes only when the
committed data changes).

Run:  python3 scripts/gen_typescript_agents.py
Then: python3 scripts/update-catalog-new-agents.py --provider typescript && npm run manifest:write:all
      && npm run docs-data:write && npm run model-policy:apply
      && npm run asset-integrity:write && npm run validate

Notes:
- model + model_reasoning_effort are policy-controlled and are projected into
  codex.toml by `npm run model-policy:apply`; this generator never emits them.
- update-catalog-new-agents.py UPSERTS: it adds ids missing from the catalog and
  re-syncs the cataloged fields of any existing id whose metadata.json diverged
  (summary, official_docs, security_notes, harnesses, version, companion_skills).
  It does not prune ids whose metadata.json was deleted — that stays a deliberate
  manual step. Re-running it on an in-sync tree is a no-op.
- asset-integrity:write must run LAST, on its own, after model-policy:apply.
