decompose SKILL.md skillA

decompose from tercel/spec-forge is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add tercel/spec-forge/decompose@git:20260916.268f496

Pins git:20260916.268f496 in mdr.lock. Pin the fingerprint instead.

Lightweight project decomposition skill. Analyzes project scope through a brief interview and determines whether the project should be treated as a single feature or split into multiple sub-features. For multi-split projects, generates a project manifest listing sub-features, dependencies, and execution order.

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

# Decompose — Project Scope Analysis

Analyze project scope and determine whether to treat it as a single feature or split into multiple sub-features before entering the spec chain.

## Core Principles

1. **Lightweight**: a brief interview, not a deep investigation — ask only what you cannot already infer
2. **Boundary-focused**: Only care about scope boundaries and dependencies
3. **No demand validation**: That is /idea's responsibility
4. **No deep research**: That is /prd's responsibility
5. **Single is valid**: Not every project needs splitting — a single-feature verdict is a good outcome

## Workflow

### Step 1: Read Context

Scan the project to understand what exists:

@../shared/project-context.md

Execute PC.1 (Project Discovery) and PC.3 (Project Profile). Prefer the fast path — resolve `<sf_scripts>` (see `@../shared/scripts.md`) and run `python3 "<sf_scripts>/sf-scan.py" --root "<project_root>"`, which returns the project structure, languages, frameworks, DB/auth signals, and the existing-doc inventory in one pass. Fall back to the manual PC.1/PC.3 scan only if `python3` is unavailable or the script is not found — switch to the fallback silently.

How to install

The exact contents, by fingerprint
mdr add tercel/spec-forge/decompose@sha256:1143528833575533

The line at the top of this page pins the label git:20260916.268f496, 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.
