semantic-ci-lint SKILL.md skillA
semantic-ci-lint from mrmps/classifier-dev is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add mrmps/classifier-dev/semantic-ci-lint@git:20260919.33ae531Pins git:20260919.33ae531 in mdr.lock. Pin the fingerprint instead.

Check every changed hunk of a pull request against conventions written in prose (naming, error handling, logging, docs) with a keyless classifier, and comment only on findings above a confidence threshold. Use when a convention cannot be expressed as a lint rule, when someone says "enforce our conventions in CI" or "check the PR against the style guide", or when the same review comment keeps being typed by hand.
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
# Lint the conventions a linter cannot express
"Log ids, never a person's name" and "never swallow a failure" are rules a
team writes down and then enforces by memory. A classifier can check them: one
label and a calibrated confidence per hunk, no prose, cheap on every push.
## One convention per call
The `instructions` field carries the convention in your own words; each call
asks about one convention. Four conventions in a single
`instructions` line put a hunk that logs a person's address and name at
`follows the convention` 0.27. The same hunk against the logging convention
alone came back `breaks the convention`, and with the whole hunk and its file
path in the input, 1.0.
Keep three labels: follows, breaks, and `the convention does not apply to this
hunk` - the third stops unrelated hunks being forced into a verdict.
## The script
`.github/semantic-lint.py` reads the output of `git diff -U0`:
```python
import json, re, sys, urllib.request
CONVENTIONS = [
("logging", "One convention only: a log line may carry ids and counts, never "
"a person's name, address or anything else that identifies them."),
…Read the whole file at its exact version.
How to install
mdr add mrmps/classifier-dev/semantic-ci-lint@sha256:553bc90d1643af33The line at the top of this page pins the label git:20260919.33ae531, 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.
