Scores feature worthiness and enforces branch-size limits against overengineering. Use when evaluating whether a feature belongs in the current scope or branch.

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 cheapest feature is the one you never build.
> Scope-guard weighs each proposed feature against its value,
> its cost, and the branch budget, so only what is earned ships.

# Scope Guard

Prevents overengineering by both Claude and human during the
brainstorm, plan, and execute workflow. Forces explicit evaluation of
every proposed feature against business value, opportunity cost, and
branch constraints.

## Philosophy

**Core Belief:** Not all features deserve implementation. Most ideas should be deferred to backlog until proven necessary.

**Three Pillars:**
1. **Worthiness Scoring** - Quantify value vs cost before building
2. **Opportunity Cost** - Compare against existing backlog
3. **Branch Discipline** - Respect size thresholds

## When To Use

- During brainstorming sessions before documenting designs
- During planning sessions before finalizing implementation plans
- When evaluating "should we add this?" decisions
- Automatically via hooks when branches approach thresholds
- When proposing new features, abstractions, or patterns

## When NOT To Use

- Bug fixes with clear, bounded scope
- Documentation-only changes
- Trivial single-file edits (< 50 lines)

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/scope-guard@sha256:a14244123f8978b1

The line at the top of this page pins the label git:20261005.41f2770, 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.
