## blq - Build Log Query

Run builds and tests via blq MCP tools, not via Bash directly:
- `mcp__blq_mcp__commands` - list available commands
- `mcp__blq_mcp__run` - run a registered command (e.g., `run(command="test")`)
- `mcp__blq_mcp__register_command` - register new commands
- `mcp__blq_mcp__status` - check current build/test status
- `mcp__blq_mcp__errors` - view errors from runs
- `mcp__blq_mcp__info` - detailed run info (supports relative refs like `+1`, `latest`)
- `mcp__blq_mcp__output` - search/filter captured logs (grep, tail, head, lines)

Do NOT use shell pipes or redirects in commands (e.g., `pytest | tail -20`).
Instead: run the command, then use `output(run_id=N, tail=20)` to filter.
