# Story 471: Bot command to show overall test coverage

## User Story

As a user on any chat transport (Matrix, WhatsApp, Slack, or web UI), I want a `coverage` command that runs the test suite with coverage instrumentation and reports the overall coverage percentage, so I can track code quality from any interface.

## Acceptance Criteria

- [ ] New bot command `coverage` registered in the command registry
- [ ] Runs test coverage (e.g. cargo llvm-cov or cargo tarpaulin) and parses the overall percentage
- [ ] Reports overall line coverage percentage in chat response
- [ ] Command appears in `help` output
- [ ] Returns a clear error if the coverage tool is not installed
- [ ] Command works across all transports (Matrix, WhatsApp, Slack, web UI) via the shared command registry
- [ ] Available as both a bot command in chat and a slash command in Claude Code
- [ ] By default, reads cached coverage from .coverage_baseline for an instant response without rerunning tests
- [ ] Optional `coverage run` variant reruns script/test_coverage and reports fresh results

## Out of Scope

- TBD
