Using with GStack¶

GStack is a workflow harness for AI coding agents (/ship, /qa, /review, /browse, …). Context Management for Agents is a context-engineering knowledge pack. They are complementary — not substitutes.

Responsibility matrix¶

Question	Use GStack	Use context-engineering skills
Ship this PR?	`/ship`, `/review`	—
Browser regression QA?	`/qa`, `/browse`	—
Context window nearly full?	—	`context-compression`, platform session skills
Verbose tool output?	—	`context-optimization`, runtime `mask_observation`
Design agent harness + HITL?	`/careful`, `/guard` (tactical)	`harness-engineering` (design)
Semantic handoff between agents?	—	`context-compression` (handoff summary)
Save workspace/git state?	`/context-save`, `/context-restore`	—
Long-horizon memory architecture?	`/learn` (tactical logs)	`memory-systems`

Install paths (namespaced)¶

Platform	GStack	Context engineering (this repo)
Claude Code	`.claude/skills/gstack/`	`.claude/skills/context-engineering/`
Cursor	`.cursor/skills/gstack/`	`.cursor/skills/context-engineering/`
Antigravity	`.agents/skills/gstack-*`	`.agents/skills/context-engineering/`

# Context engineering (this repo)
npx context-management-for-agents --platform cursor --setup

# GStack (separate install — see gstack README)
git clone --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup

The --setup flag creates per-skill discovery symlinks (GStack-compatible layout).

MCP servers¶

You may run both:

GStack browse / workflow tools
Context-skills runtime (runtime/mcp/server.py) for route_task, compact_session, run_context_pipeline

Disable unused MCP servers per task — tool schema bloat competes with code context (tool-design).

Example session¶

/office-hours or /plan-eng-review (GStack) — shape the feature
Implement with Cursor Agent
Context ring fills → read context-compression or call runtime compact_session
/qa (GStack) — browser verification
/ship (GStack) — tests, PR
