The machine-readable provider-result / install-preview / provenance contracts live under `schemas/`; the actual search, preview/apply, update, uninstall, and harness placement must be supplied by the current environment's provider/installer adapter. When that capability isn't available, the only honest output is a manual-review plan — never claim a search or install actually happened. ## The core five steps (whenever a task needs a capability you don't have) 1. **Check the team's own shelf first**: `{{TEAM_SKILL_SHELF, e.g. <team-root>/methodology/skill-library/}}` — reuse what the team has already sedimented before you reinvent it. 2. **Search for an existing wheel** — go through whatever provider is genuinely available in the current environment, and get a structur
