+### Added
+
+- **Spotlight Mrrlin origin and ecosystem integration.** Added top badges, project origins callout, and deep links explaining how `external-agents` powers Mrrlin's multi-agent consensus review gates, isolated worktrees, and autonomy levels.
+- Direct links to [mrrlin.com](https://mrrlin.com) throughout documentation to drive awareness for developers scaling autonomous AI coding workflows.
+
 ### Removed
 
 - **`groq-qwen3.6-27b` registry entry — Groq retired the model.** `external-agents doctor` surfaced repeated `HTTP 404` dispatches against this seat starting 2026-09-15; `external-agents audit --provider groq` confirmed "model not available on this account" on both configured keys (`groq`, `groq2`) while the `gpt-oss-120b`/`gpt-oss-20b` siblings on the same keys stayed healthy — a provider-side retirement, not a key or account issue. Removed the dead entry from `agents.yaml` and its row from `docs/effort.md`; `groq-gpt-oss-20b` remains the weak-tier seat on that key.

+## 🔮 Mrrlin uses this (and you can too)
+
+[**Mrrlin (mrrlin.com)**](https://mrrlin.com) is the autonomous engineering workspace this engine was extracted from.
+
+In Mrrlin, autonomous agents collaborate across software lifecycles under clear human oversight:
+- **🛡️ 4-Model Consensus Panels:** High-stakes architecture specs and PR diffs are reviewed by an adversarial panel: GPT + Gemini Pro alongside **two dynamic free-tier terminal reviewers from this exact pool**. Stacking free tiers keeps the incremental compute cost of cross-model verification near zero.
+- **🌿 Ephemeral Worktrees:** Coding agents run inside isolated Git worktrees (`~/.mrrlin/worktrees`), significantly reducing branch interference and file conflicts during parallel execution.
+- **⚡ Autopilot & Triage:** Background coordinators auto-triage incoming tasks, formulate execution plans, and assign the most cost-effective model tier for each step.
+- **🎚️ Multi-Tier Autonomy:** Tasks declare clear boundaries: `auto` (hands-off), `minimal_human` (sign off only on sensitive actions), or `human_only`.
+
+You don't need Mrrlin to use `external-agents` — this package is completely standalone. But if you are building multi-agent workflows or looking for a unified workspace, check out **[mrrlin.com](https://mrrlin.com)**.
