Reference data, not a reviewer. Compute web accessibility scores (0-100, A-F grades) with severity scoring, confidence levels, and remediation tracking across audits.
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
## Web Severity Scoring This file describes the scoring that `skills/a11y-core/scripts/merge-findings.mjs` computes for every rendered report. Where this file and the script differ, the script decides. A score is not a conformance claim: only a finding-free review against every criterion at the target level supports "conforms". ## Score formula ```text penalty = sum over findings of severity_weight x confidence_factor checks = max(number of findings + number of passed checks, 10) score = max(0, round(100 - (penalty / checks) x 20)) ``` Each severity, with its weight. | Severity | Weight | |---|---| | critical | 10 | | serious | 5 | | moderate | 2 | | minor | 1 | Dividing by the number of checks keeps a large audit from scoring lower only because it looked at more. The floor of 10 checks stops a tiny audit with one finding from scoring near zero. **Example:** one critical finding at high confidence and 9 passed checks gives penalty 10, checks 10, score 100 - (10 / 10) x 20 = 80, grade B. ## Grades Each score band, with its grade. | Score | Grade | |---|---| | 90-100 | A | | 80-89 | B | | 70-79 | C | | 60-69 | D | | 0-59 | F | ## Confidence …

How to install
mdr add community-access/accessibility-agents/kb-web-severity-scoring@sha256:f1a405aa937d244aThe line at the top of this page pins the label git:20261028.d473f9f, 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.
