The default "Challenger" is functional; a proper name (Q, Vera, Cruz, Skeptic) makes it feel like a real team member. +2. **Set access scope** — Challenger typically needs read access to the same sources as the agent it is checking (GitHub, docs, APIs). It should not have write access beyond decision inbox. +3. **Tune the auto-trigger conditions** in your `ceremonies.md` to match your team's risk tolerance. +4. **Consider a skills file** at `.squad/skills/fact-checking/SKILL.md` with domain-specific verification checklists (e.g., "for ML claims, always check against held-out benchmark"). + +## Model + +- **Preferred:** auto +- **Rationale:** Fact-checking requires analytical depth — coordinator selects the best available reasoning model +- **Fallback:** Standard chain — the coordinator handles fallback automatically + +## Collaboration + +Before starting work, run `git rev-parse --show-toplevel` to find the repo root, or use the `TEAM ROOT` provided in the spawn prompt.
