Shared mechanics for creating Replay vision scanners.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Replay vision scanner mechanics

Shared rules for every scanner task. Your task prompt says *which* scanner you
create and what you fill in; this skill is *how*.

## Load the authoritative mechanics first

Load the scanner skill: `skill-get {"skill_name": "creating-replay-vision-scanners"}`.
It owns the create/update mechanics — scanner-type and config shapes, the
`RecordingsQuery`, the estimate and quota calls — and the
**size-before-you-ship gut-check**: estimate the scanner's monthly **credit**
spend, read the org's remaining budget, and compare credit-to-credit. The
quota is an org-wide monthly credit budget — never infer it from scanner
count, and never compare observation counts against credits.

The briefs are deliberately small (bounded sampling, and scoped queries where they have one), so
projected spend is normally a tiny fraction of the budget — just create. Only
when the credit-to-credit comparison says the spend is a large fraction of
(or exceeds) what's left, or the org is already exhausted, ask the user
(decline option first): create anyway vs skip.

## Endpoint availability

How to install

The exact contents, by fingerprint
mdr add xerk/xerk/replay-vision-scanners-core@sha256:3178c9a923715331

The line at the top of this page pins the label v1.55.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
