# `Excessibility.MCP.Tools.CheckWork`
[🔗](https://github.com/lessthanseventy/excessibility/blob/v0.18.1/lib/excessibility/mcp/tools/check_work.ex#L1)

Composite MCP tool that runs tests, accessibility checks, and optional
performance analysis in one call.

Designed to be called automatically by Claude after modifying code.
Runs `mix test`, then `mix excessibility`, and optionally
`mix excessibility.debug` for performance analysis.

# `build_summary`

Builds a human-readable summary from an a11y result and optional perf result.

# `classify_violations`

Classifies a list of violations as `:clean`, `:minor`, or `:critical`.

Critical impacts are "critical" and "serious". If any violation has a critical
impact, returns `:critical`. If there are only minor/moderate violations,
returns `:minor`. If there are no violations, returns `:clean`.

# `extract_violations`

Extracts a violations list from an a11y result, handling both structured
and raw output formats.

- If the result has a `"violations"` key, uses it directly.
- If it only has `"output"` (raw text), returns `[]` for success or a
  synthetic violation with `"unknown"` impact for non-zero exits.
