Release @razroo/iso-route v0.1.0 · Agent-Pattern-Labs/iso

Initial release of @razroo/iso-route — one model policy, every harness.

Declare a default model plus named roles once; iso-route compiles that policy into each harness's native config:

.claude/settings.json (default model) + a resolved role map (.claude/iso-route.resolved.json) that iso-harness consumes when stamping per-subagent frontmatter
.codex/config.toml with [profiles.<role>] blocks
opencode.json with provider-qualified models + per-agent overrides
.cursor/iso-route.md advisory README note (Cursor has no programmatic model binding)

Scope (v0.1)

Config emission for Claude Code, Codex, OpenCode; README note for Cursor
Role-level reasoning effort (low / medium / high)
Fallback chains recorded in the resolved map, but not encoded into harness config — runtime routing belongs in proxy layers (OpenRouter, LiteLLM, Portkey), not a build-time transpiler

Warns loudly where a harness can't express a construct: non-Anthropic roles under Claude Code, fallback chains anywhere, Cursor entirely.

npm install -D @razroo/iso-route
iso-route build models.yaml --out .

See the package README for the full policy shape and fan-out mapping table.
