cad-why from crenshawdev/cadence is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add crenshawdev/cadence/cad-why@git:20261029.0ae5ff0Pins git:20261029.0ae5ff0 in mdr.lock. Pin the fingerprint instead.

Why is this code like this - a git-log chain over one file[:line], joined to the phase, task, decision, deviation and review record on disk.
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
<objective>
Answer "why is this code like this" from the record already on disk, at one
file and line. Read-only: no write, no dispatch, no summarization - the seam
does the whole join and this skill relays what it returns.
</objective>
<process>
1. Run the seam with the query as ONE single-quoted literal word:
`node "${CLAUDE_PLUGIN_ROOT}/cadence-core/bin/why.mjs" '<path>[:<line>]' --dir .`
Single quotes, never double: `$ARGUMENTS` is caller-supplied, and a
double-quoted `$(...)` or backtick inside it runs before Node starts. A
query containing a single quote is refused here, never escaped. Parse the
one JSON line it prints.
2. `ok:false` - state the `reason` and `detail` fields plainly and stop.
3. `ok:true` - print the `text` field VERBATIM and nothing else: no summary
before it, no commentary after it, no reformatting. `text` is already the
whole answer, quoted from the record in its own words - reformatting it
here would make the byte-identity a reader can check against the seam's
own output false.
</process>Read the whole file at its exact version.
How to install
mdr add crenshawdev/cadence/cad-why@sha256:c90a6d99d48350c2The line at the top of this page pins the label git:20261029.0ae5ff0, 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.
