Code conventions for names, file layout, docstrings and the source of truth. Use when writing or reviewing code, when a review comment asks what a name means or why a thing exists, when a docstring or comment explains how the code works, when a helper sits outside its owning class, or when a value is parsed out of a string, read from a file, or taken from a built-in default instead of read from where it is stored.

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

# Code naming and layout

Four rules for code in any repo. Each one puts the meaning where the reader
looks first: the name, the file, the first line of the docstring, the stored
column.

## No short or cute names, ever

- A name is spelled out in full. A two-letter name is wrong; a three-letter
  name has to be a real word (`datadog_steps_loader` not `dd`, `config` not
  `cfg`, `query_params` not `q`, `trigger` not `trig`, `job_family_names`
  not `F`).
- A name carries the domain concept, so the reader never opens the body to
  learn what it holds: a class is named for the thing it models with its
  vendor or domain in the name (`GitlabCiYaml`, `PipelineDependencyGraph`,
  `RequestBudget`), never a generic private class (`_Loader`, `_Pool`); a
  function is a verb plus its object (`parse_yaml`, `run_git_checkout`).
- A route, page key or JSON key says what it returns, so a reader of the
  path alone knows the payload.
- A constant says why it exists, with its role in the name
  (`ERROR_FILE_UNREADABLE_REASON`, `STEP_DURATION_SECONDS`), never a bare
  value name.
- A legend that maps short names to their meanings at the top of a file is
…

How to install

The exact contents, by fingerprint
mdr add edbertchan/catstack/code-naming@sha256:806201710b29849c

The line at the top of this page pins the label git:20261030.53ce6d5, 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.
