A Codex skill for generating minimal zine-style editorial poster prompts and images.

Agent-first screenshots — an agent drives the real app via CDP and produces clean, defect-free product screenshots (newsletters, landing pages, social, decks, PR). Dual-channel verification (DOM + pixels + vision) in a capture loop. Use for any "take/redo screenshots of the app" task.

Whole-repo audits in eight modes. Codebase — merged structural + correctness audit, should this exist AND does it do what it promises. Triggers "nuclear review", "code judo", "whole codebase review", "should this exist", "adversarial audit", "fable audit", "correctness audit", "expectation gaps". Docs/Process — doc drift, walkable journeys. Triggers "audit the docs", "doc drift", "process audit", "walk the journeys". Performance — measured-only perf audit; no finding without a number. Triggers "perf audit", "performance audit", "why is it slow", "bundle audit", "build is slow". Threat-model — abuse paths. Triggers "threat model", "STRIDE", "attack surface". Motion — animation audit. Triggers "motion audit", "audit the animations". SEO — discoverability + AEO. Triggers "seo audit", "aeo", "answer engine", "llms.txt", "rank better". Debt — `SHORTCUT:` ledger. Triggers "debt ledger", "shortcut ledger". Owns bare "audit the codebase"; single-page CWV fix loops go to /lighthouse.

Rewrite existing text under the EW anti-AI rules and the writer's voice profile, then show a structured before/after with specific failure analysis. Use when the user pastes a draft and asks to fix, tighten, de-slop, humanize, critique, or improve it.

Searches code specifically for potential bugs, edge cases, race conditions, and incorrect assumptions rather than general style/quality. Use when the goal is finding what's broken, not improving what already works.

Audit or edit Sero Markdown documentation and other product prose to remove AI-writing patterns while preserving technical meaning, product terminology, links, examples, and the repository voice. Use when the user asks to humanize, de-slop, tighten, simplify, rewrite, or audit Sero documentation, README text, UI copy, release notes, plans, or specifications for AI tells. Also use when prose needs ASD-STE100 Simplified Technical English. Do not use for code review or for creative and promotional writing.

Review a PR, a branch, or a diff in the Sero monorepo and post the findings. Use when the user asks to review code, review a PR, re-review after new commits, check a branch before merge, or double-check an earlier review. Trigger on phrases like "review this PR", "review the delta", "check the changes", "double check it", or any request that ends in review findings. Use this in place of the built-in code-review skill.

Review changes on current branch and output a structured review. Optionally post to PR with --pr flag, or apply non-blocking follow-ups inline with --apply-followups.
