# `mix release.smoke`
[🔗](https://github.com/andreasronge/ptc_runner/blob/main/lib/mix/tasks/release.smoke.ex#L1)

Runs the local release-readiness smoke checks used before pushing a release tag.

    mix release.smoke

This task does not publish anything. It runs deterministic root release checks,
root and MCP memory soak checks, then builds and smoke-tests the sibling
`mcp_server` release binary.

The MCP smoke builds `mcp_server` with `MIX_ENV=prod mix release --overwrite`
and then runs `mcp_server/test/integration/release_stdio_test.exs` against the
built binary. Set `PTC_SOAK_ITERATIONS` to tune soak duration; it defaults to
`3000`.
