# Accessibility Fix

Fix a broken page so keyboard, screen-reader and contrast checks pass.

## What it measures

Whether a fixed HTML page really repairs injected keyboard, screen-reader, and contrast defects without deleting or hiding content.

Category: `coding`. Status: `alpha`.

## How to run

```console
$ npx benchmark-accessibility-fix list
$ npx benchmark-accessibility-fix run --model <model-id> --provider openrouter
$ npx benchmark-accessibility-fix score results.json
```

`--provider mock` runs the whole benchmark offline with no keys. Real models run
through OpenRouter (`OPENROUTER_API_KEY`) or any OpenAI-compatible base URL
(`OPENAI_BASE_URL`, `OPENAI_API_KEY`).

## Data fields

`data/tasks.jsonl` holds 40 tasks, one JSON object per line
(kinds: 40 single).

| field | type |
|---|---|
| `id` | string |
| `kind` | string |
| `prompt` | string |
| `expected` | string |
| `metadata` | object |

## Provenance

# Accessibility Fix provenance

This file is generated from the benchmark definition.

## Synthetic accessibility fixtures

- Kind: `synthetic`
- URL: https://github.com/pooriaarab/benchmark-accessibility-fix/blob/main/scripts/gen-tasks.mjs
- Licence: `MIT`
- Retrieved: 2026-10-16T00:00:00.000Z
- How to get it: Run `npm run generate:tasks` (or `node scripts/gen-tasks.mjs --seed 20261015` after `npm run build`) from the repository root. The generator grades every reference page with the built package and re-draws until it scores 1. A hidden split uses another seed: `node scripts/gen-tasks.mjs --seed <n> --split hidden --out <path>`; hidden files use a11yh- ids and stay out of git and npm.
- Contamination notes: Public tasks use seed 20261015. Treat them as possibly in training data; use a separately seeded hidden split for final comparisons.
- Refresh: Change the seed, run the generator, and review the JSONL diff.


## Grader

Deterministic static analysis of the fixed HTML: ten WCAG-cited checks score defects fixed, minus regressions, content loss, element removal, and hiding abuse. Model judging is off.

## Limitations

This dataset contains only the public task split (40 tasks).
Hidden evaluation splits use a private seed and are deliberately not part of
this dataset. Source kinds: synthetic. These are evaluation prompts
for the `benchmark-accessibility-fix` benchmark, not training data; scoring requires the package's
deterministic grader. See PROVENANCE.md for contamination notes.
