Write, review, and repair Elixir or Erlang code with verified syntax, exact API arities, OTP lifecycle handling, and executable checks. Use for .ex/.exs, mix.exs, GenServer, supervision, Ecto, Phoenix, and BEAM runtime bugs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Elixir and OTP: verify the code path ## Workflow 1. Read the repository instructions, `.tool-versions`, `mix.exs`, and relevant existing modules/tests. Use its matched Elixir/OTP pair; run `elixir --version` and `mix --version`. Do not hardcode another developer's installation path. 2. Read [syntax and API examples](references/syntax.md) for matching, guards, strings, maps, pipes, and error handling. Read [OTP and integration pitfalls](references/gotchas.md) for servers, tasks, configuration, and Ecto. 3. Verify external calls against the installed dependency source or its pinned HexDocs version. `Code.ensure_loaded!/1` followed by `function_exported?/3` checks functions; use `macro_exported?/3` for macros. A missing module is not evidence that its documented API does not exist. 4. Write the smallest implementation following the project's conventions. Use explicit success/error return contracts at boundaries, validate external data, and keep arbitrary input as strings rather than creating atoms. 5. Run `mix format --check-formatted`, `mix compile --warnings-as-errors`, and the …

How to install
mdr add miosa-osa/osa/elixir-otp@sha256:77cc1869208c45a5The line at the top of this page pins the label git:20260914.92db90a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
