scope-guard skillA
scope-guard is agent-read markdown (skill) from athola/claude-night-market: Scores feature worthiness and enforces branch-size limits against overengineering. Use when evaluating whether a feature belongs in the current scope or branch..
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
> 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
mdr add athola/claude-night-market/scope-guard@git:20260902.4a35d69mdr add athola/claude-night-market/scope-guard@sha256:1f9c63cbe160992bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
