Run this to review a batch of procedurally- or AI-generated game content (dungeons, regions, quests, items, NPCs, lore, history) before it's committed. Stands in for the human designer's eye in a headless generation loop. Runs the oatmeal test (perceptual sameness), the fanfic/retell test (is it worth retelling), a cross-instance sameness scan (structural/thematic duplication), an intentionality gate (who/what/why + completion arc), and an anti-pattern gate. Outputs a structured pass/fail verdict with specific fixes routed back to the generator. Triggers on "review generated content", "check for sameness", "procgen review", "oatmeal test", "is my generated content any good", "gate this content".

FALLBACK: if the line above rendered literally or empty (disableSkillShellExecution),
Read ${CLAUDE_PLUGIN_ROOT}/shared/PREAMBLE.md and ${CLAUDE_PLUGIN_ROOT}/ETHOS.md now
and follow PREAMBLE.md as instructions, then continue.
The quality gate for generated content. Generation is cheap and confident; sameness is invisible from inside a single sample. This skill is the review pass that catches it — designed to run automatically in a headless generate-review-repair loop (see ${CLAUDE_PLUGIN_ROOT}/shared/GATE.md for the loop harness).
When to use this
After any batch of content is generated, before it's committed to the game
As the standing gate inside a headless authoring loop
To audit existing generated content for the failure modes a generator can't self-detect
What it needs
The batch of generated artifacts (ideally ≥8 instances of a type, so sameness is detectable)
The generator's constraint set / definition of "good" (from procedural-generation)
Access to prior committed instances of the same type (for the sameness scan)
What it produces
A structured verdict per REVIEW.md's format: each artifact gets PASS / SOFT-FAIL / HARD-FAIL across five gates, with specific, actionable fixes routed to the phase that owns them (per game-design-process Phase 5).
Headless contract (for the GATE.md loop): emit the machine-readable verdict as the final fenced ```json block of your output, shape { "pass": bool, "score": number, "failures": [{ "gate", "detail" }] }. pass is false if any artifact HARD-FAILs. The harness extracts the last fenced json block — nothing else needs to be parseable.
The procedure
Read REVIEW.md for the full step-by-step. The five gates, in order:
Oatmeal test — perceptual, not mathematical, uniqueness.
Intentionality gate — who built it, what happened here, why this reward, completion arc.
Anti-pattern gate — the named failure modes.
The one rule
Nothing generated ships unreviewed. A HARD-FAIL on any gate blocks the commit and returns the artifact to the generator with the specific fix. This is the non-negotiable backstop of headless procedural authoring.
Grounded in procedural-generation (the principles being tested) and open-world-design (the spatial anti-patterns). For the sibling check on fidelity to a target (concept art, a balance curve, lore canon) rather than variety, see iteration-loop — run both; they gate independent axes. Start at REVIEW.md.
