Explains code with WHAT, WHY, ANALOGY, DIAGRAM, CRUXES, and GOTCHAS. Use when you want to know how code works or when the user asks "how does this work?".

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.

<objective>
*Analyze* the source code of <getopt-arguments/>, and its directly related source

<flow>

1.  <step id="STEP 1: Investigate Code Base">
    Investigate the code. If the code base is large, you *MUST* use
    the `Agent` tool (not inline work) to create multiple sub-agents to
    split the investigation task into appropriate chunks.

2.  <step id="STEP 2: WHAT and WHY">
    **Explain the WHAT and WHY**.

    First, explain *WHAT* the code does (*functionality*).
    Second, explain *WHY* the code does it (*rationale*).

    Keep your explanations *brief* and *concise*.

    The project source artifacts are classified as a *black box*, so the

How to install

The exact contents, by fingerprint
mdr add rse/ase/ase-code-explain@sha256:f28f5aea8c2870a5

The line at the top of this page pins the label git:20260804.af0eeb8, 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.
