datacore-gstack

Sprint workflow integration for Datacore, powered by gstack by Garry Tan.

Adds persistent memory, autonomous quality gates, enriched retros, and a sprint orchestrator on top of gstack's battle-tested sprint skills.

What it does

Skill	Purpose
/sprint	Orchestrates idea-to-ship: office hours, planning, build, quality gates, ship, retro
/gate	Runs code review + QA + security audit as sequential quality gates
/retro-dc	Wraps gstack /retro with engram capture and enriched journal entries

What Datacore adds on top of gstack

• Persistent memory: review findings, bug patterns, and shipping insights become engrams that inform future sprints
• Autonomous execution: quality gates run overnight via nightshift after AI builds complete
• Enriched retros: velocity metrics, session classification, and improvement insights captured as engrams
• Sprint tracking: full audit trail from idea through shipped product
• Journal integration: every phase logs to the Datacore knowledge base

Requirements

• Datacore installed
• gstack installed at ~/.claude/skills/gstack/

Install

# Clone into your Datacore modules directory
git clone https://github.com/datacore-one/datacore-gstack .datacore/modules/gstack

Setup

Nothing runs these steps automatically; do them once after cloning.

1. Install gstack if ~/.claude/skills/gstack/ does not exist yet:

   git clone https://github.com/garrytan/gstack.git ~/.claude/skills/gstack
   cd ~/.claude/skills/gstack && ./setup && cd -

2. Link this module's skills into Claude Code, from the module directory (.datacore/modules/gstack). Each skills/<name>/ becomes ~/.claude/skills/gstack-dc:<name>; existing links are left alone:

   for skill_dir in skills/*/; do
     skill_name=$(basename "$skill_dir")
     target="$HOME/.claude/skills/gstack-dc:$skill_name"
     [ -e "$target" ] || ln -s "$(pwd)/$skill_dir" "$target"
   done

Then use /sprint, /retro-dc or /gate.

Engram Pack: garry-tan-v1

This module includes a knowledge pack distilling shipping methodology from gstack into reusable engrams:

• 3-Strike Debugging Rule
• WTF-Likelihood Heuristic
• Fix-First Code Review Flow
• Scope Drift Detection
• Verification-Before-Claims Protocol
• Session Classification
• Boil the Lake Principle
• Anti-Sycophancy
• Scope Lock During Debugging
• Blast Radius Gate

These patterns work independently of gstack and improve any AI-assisted development workflow.

Architecture

gstack (Garry maintains, you update via git pull)
  ~/.claude/skills/gstack/

datacore-gstack (this module, thin integration layer)
  .datacore/modules/gstack/
    skills/sprint/    -- orchestrates gstack skills with Datacore plumbing
    skills/gate/      -- quality gate runner for nightshift
    skills/retro-dc/  -- retro wrapper with engram capture
    agents/           -- nightshift gate runner agent
    lib/              -- bridge: reads gstack outputs, routes to Datacore

gstack is a runtime dependency, not bundled. Updates are independent.
