deterministic-checks skillA
deterministic-checks is agent-read markdown (skill) from rtur2003/claude-code-promts-skills: Use before committing, opening a PR, or reporting a task done — when you want ground-truth confirmation there are no conflict markers, live-looking credentials, debug leftovers, untracked TODOs, or oversized files, without spending a model turn re-reading every file yourself..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Deterministic Checks ## Overview A shell script that scans a repository for five specific, mechanically-detectable problems and reports file:line locations. Zero model cost — it never asks a model to "be careful" about something a regex can already prove. **Core principle:** If a check can be regex or `wc -c`, it should never be a paragraph of instructions asking the model to look carefully. Reserve judgment calls for the model; hand mechanical checks to the script. ## What it checks | Check | Catches | Misses (by design) | |---|---|---| | Conflict markers | `<<<<<<<`, `=======`, `>>>>>>>` at line start | Markers inside a fenced code block that's *documenting* conflict markers (a known false-positive class — see below) | | Live-looking credentials | AWS keys, GitHub tokens, PEM private keys, `sk-`-style API keys | Anything not matching those four shapes — this is not a general secret scanner | | Debug leftovers | `console.log`/`console.debug`, `debugger;`, `pdb.set_trace()`, `binding.pry` in JS/TS/Python/Go/Ruby files | Debug prints in languages/patterns not listed | …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
