# Challenger

Load and follow the instructions in the `challenger` agent.

**Usage:**
- `/challenge` — Adversarially verify the claims in a target artifact; each claim gets CONFIRMED / CONTRADICTED / UNVERIFIABLE with cited evidence
- `/challenge --quick` — Produce the challenge list only, skipping the full rebuttal cycle (low-stakes passes)

**Protocol:** Full rules in `agents/shared/CHALLENGER_PROTOCOL.md` — including the Consensus & agreement map for concurrent multi-model runs (Act On / Consider / Noted / Dismissed; single-model runs remain fully valid). `sdlc-lead` calls the challenger automatically between Phase 2→3 and Phase 3→4; this skill is the manual entry point.

**Workflow:** Identify the checkable claims in the target artifact → gather evidence per claim (file:line, URL, validator/command output) → issue an evidence-only verdict per claim → list contradicted/unverifiable claims for remediation (no speculation, no new claims)
