#!/usr/bin/env python3 """Generator: Snowflake board agents + companion skills from per-agent JSON data files. Reads every ``scripts/snowflake_data/agents/*.json`` (one file per agent) and emits, in the house style already established by the AWS/Azure/OCI review boards and the Azure/OCI live-guard boards: agents/snowflake//AGENT.md agents/snowflake//metadata.json agents/snowflake//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/snowflake//{PERMISSIONS,PREFLIGHT,ROLLBACK}.md (live guards only) agents/snowflake//README.md (maestro only) skills/snowflake//SKILL.md skills/snowflake//metadata.json skills/snowflake//references/*.md All judgment lives in the per-agent data files; this script only renders structure, so the board stays internally consistent and reproducible — behaviour changes only when the committed data changes. The generator never consults the wall clock. Run: python3 scripts/gen_snowflake_agents.py Then: python3 scripts/update-catalog-new-agents.py --provider snowflake && 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. - Live guards are `mutating-runtime` by DECLARATION, but — exactly as the pre-existing snowflake/azure/oci live guards do — they are granted NO execution tool in any harness adapter (`sandbox_mode = "read-only"`, copilot tools read/search only). The guard's job is to produce the approval-gated, preflighted, rollback-backed statement; a human runs it. Widening that grant is a deliberate, reviewable change, never a side effect here. - asset-integrity:write must run LAST, on its own, after model-policy:apply.
