Designing Replay Vision Scanners
Designs a Replay Vision scanner that produces trustworthy observations: one visible question per scanner, a type chosen from the answer shape, a query that selects only sessions able to answer it, a prompt that demands on-screen proof and allows no or inconclusive, a model picked by the cost of a wrong answer, and a first-batch test pass. Sizing and the create call stay in creating-replay-vision-scanners.\nTRIGGER when: user wants to design, draft, or improve a Replay Vision scanner or its prompt, asks what to scan for, asks why a scanner returns vague observations, or asks an agent to propose scanners for a product.\nDO NOT TRIGGER when: the question and prompt are settled and the job is to size and create (use creating-replay-vision-scanners), the scanner targets one experiment (use scanning-experiments-with-replay-vision), or the job is to read existing observations (use exploring-replay-vision-observations).

From the source SKILL.md
A scanner is one prompt applied to one recording at a time. It watches the recording and writes an observation. Replay Vision fixes the watching part. It does not fix the thinking part. The thinking is the design work this skill covers.
What this skill does
Designing Replay Vision Scanners is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/designing-replay-vision-scanners/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Designing Replay Vision Scanners Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Designing Replay Vision Scanners skill?
Use Designing Replay Vision Scanners when your Claude Code task falls under the Science & Research category — specifically in the science misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Designing Replay Vision Scanners" or describe the task and let Claude pick). Browse related skills at
/category/science/.
What is a Claude Code skill and how does the Designing Replay Vision Scanners skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Designing Replay Vision Scanners is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category. Learn more at
