This skill should be used when the user asks about "spec system", "session workflow", "createprd", "plansession", "implement session", "validate session", "phase build", "session scope", "task checklist", or when working in a project containing .spec_system/ directory. Provides guidance for specification-driven AI development workflows.
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
# Apex Spec Workflow
A specification-driven workflow system for AI-assisted development that breaks large projects into manageable 2-4 hour sessions with 12-25 tasks each.
## Core Philosophy
**1 session = 1 spec = 2-4 hours (12-25 tasks)**
Break large projects into manageable, well-scoped implementation sessions that fit within AI context windows and human attention spans.
A collection of sessions is a phase. A collection of phases is a mature/late technical PRD.
## The 13-Command Workflow
The workflow has **3 distinct stages**:
### Stage 1: INITIALIZATION (One-Time Setup)
```text
/initspec -> Set up spec system in project
|
v
/createprd -> Generate PRD from requirements doc (optional)
OR OR
[User Action] -> Manually populate PRD with requirements
|
v
/createuxprd -> Generate UX PRD from design docs (optional)
OR OR
[User Action] -> Manually populate UX PRD with requirements
|
v
/phasebuild -> Create first phase structure (session stubs)
```
### Stage 2: SESSIONS WORKFLOW (Repeat Until Phase Complete)

How to install
mdr add moshehbenavraham/apex-spec-system/Apex Spec Workflow@sha256:217e13f1db621cd4The line at the top of this page pins the label v2.0.4-beta, 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.
