Generating mod learning envs

Use this skill to create JSON envs consumed by /mods learn --env=<path> or bun scripts/mod-learning/learn-mod.ts --env <path>. An env describes the mod behavior to learn and the scenario-suite eval used to score candidates.

Workflow

1. Define the behavior and eval before writing JSON.
   • What should the mod do? Tool, turn event, tool event, provider, command, status, etc.
   • What would a placebo/no-op mod fail?
   • What unique sentinel strings make success unambiguous?
2. Choose a path:
   • Repo example: docs/examples/mods/learning/<slug>.env.json
   • Local/private: any user-requested path
3. Draft strict JSON. Start from assets/mod-learning-env.template.json if useful. No comments or trailing commas.
4. Prefer evaluation.scenarios with at least:
   • happy path
   • discrimination/exact-target path
   • negative control
5. Validate:
