justify SKILL.md skillA

justify from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add athola/claude-night-market/justify@git:20260713.f98719b

Pins git:20260713.f98719b in mdr.lock. Pin the fingerprint instead.

Audits changes for additive bias and Iron Law compliance. Use when reviewing completed work before merging or after AI-assisted implementation.

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

> The simplest change that fixes the problem is the
> safest change to merge.
> Adding code is easy. Removing the need for code is
> engineering.

# Justify

## The Additive Bias Problem

AI models are trained to be helpful, which creates
a systematic bias toward *adding* code rather than
*fixing* root causes:

| AI Default Behavior | Correct Behavior |
|---------------------|------------------|
| Add a workaround | Fix the root cause |
| Modify test expectations | Fix the implementation |
| Create a new helper | Use an existing one |
| Add error handling | Prevent the error |
| Add a compatibility shim | Remove the old code |
| Wrap in try/catch | Fix the exception source |

This skill audits changes for these patterns and
requires explicit justification for each.

## When To Use

- After completing implementation work
- Before committing or creating PRs
- When reviewing your own changes for quality
- When scope-guard flags RED/YELLOW zone

## When NOT To Use

- Before writing the code, because this audits work already done (use
  `imbue:karpathy-principles`)
- Deciding whether a feature belongs in scope (use `imbue:scope-guard`)

## Audit Protocol

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/justify@sha256:9f5b2d8c530bee9b

The line at the top of this page pins the label git:20260713.f98719b, 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.
