Cooperative multi-agent engineering suite for Antigravity. Consolidates the best of Plannotator (visual plan & code review) and Matt Pocock's Skills (engineering workflows) into a single, lightweight, configuration-only plugin.
No binary dependencies. No hooks. No scripts. One slash command, four specialized agents, TOON-serialized output.
agy plugin install ./antigravity-supertoolsVerify:
agy plugin listEvery interaction goes through a single entry point:
/supertools <your request>
The /supertools skill classifies your intent and delegates to the right agent:
| Intent | Agent | Examples |
|---|---|---|
| Plan, design, grill, domain modeling | Architect | "plan a new auth module", "grill me on this design", "update the glossary" |
| Implement, TDD, prototype | Developer | "implement with TDD", "build a prototype", "write the feature" |
| Code review, diff analysis, annotations | Reviewer | "review my changes", "annotate this file", "check the last diff" |
| Bug diagnosis, regression tracing | Debugger | "there's a bug in auth", "diagnose this failure", "why is this slow" |
| Ultra-terse communication | (caveman mode) | "caveman mode", "be terse" |
| Session handoff | (handoff) | "handoff", "summarize for next session" |
| Agent | Consolidates | Core Loop |
|---|---|---|
| Architect | grill-me, grill-with-docs, domain-modeling, to-prd, to-issues, improve-codebase-architecture | Grill → plan → update memory |
| Developer | tdd, prototype, implement, codebase-design | RED → GREEN → REFACTOR → self-reflect |
| Reviewer | plannotator-review, plannotator-annotate, plannotator-last, plannotator-visual-explainer | Diff → annotate → TOON table output |
| Debugger | diagnosing-bugs | Reproduce → minimise → hypothesise → instrument → fix |
The Architect maintains a memory/ folder of interlinked markdown using [[wikilinks]]:
memory/
├── domain.md # Glossary, ubiquitous language
├── architecture.md # Module map, seams, design decisions
└── index.md # Unified TOON file index
All structured data uses TOON (Token-Oriented Object Notation) for 30–60% token savings:
[3]{task,status,assignee}:
Implement auth middleware,done,developer
Write regression test,in-progress,debugger
Update domain glossary,todo,architect
