- Knowledge Sources
- Contributing
- 4x Faster — Parallel execution with wave-based execution
- Pattern Reuse — Codebase pattern discovery prevents reinventing wheels
- Higher Quality — Specialized harness agents + TDD + verification gates + contract-first
- Built-in Security — OWASP scanning, secrets/PII detection on critical tasks
- Resilient — Pre-mortem analysis, failure handling, auto-replanning
- Accessibility-First — WCAG compliance validated at spec and runtime layers
- Safe DevOps — Idempotent operations, health checks, mandatory approval gates
- Constructive Critique — gem- critic challenges assumptions, finds edge cases
- Established Patterns — Uses library/harness conventions over custom implementations
- Source Verified — Every factual claim cites its source; no guesswork
- Knowledge-Driven — Prioritized sources (PRD → codebase → AGENTS.md → Context7 → docs)
- Continuous Learning — Memory tool persists patterns, gotchas, user preferences across sessions
- Auto-Skills — Agents extract reusable SKILL.md files from successful tasks (high confidence: auto, medium: confirm)
- Skills & Guidelines — Built-in skill & guidelines (web-design-guidelines)
- Spec-Driven — Multi-step refinement defines "what" before "how"
- Verified-Plan — Complex tasks: Plan → Verification → Critic
- Traceable — Self-documenting IDs link requirements → tasks → tests → evidence
- Intent vs. Compliance — Shifts the burden from writing "perfect prompts" to enforcing strict, YAML-based approval gates
- Diagnose-then-Fix — gem-debugger diagnoses → gem-implementer fixes → re-verifies
- Pre-Mortem — Failure modes identified BEFORE execution
- Contract-First — Contract tests written before implementation
Optimized for reduced LLM token consumption without quality loss:
- Concise Output — No preamble, no meta commentary, no verbose explanations
- Strict Formats — JSON/YAML exactly matching schemas — eliminates parse errors and retries
- Empty is OK — Skip empty arrays, nulls, verbose fields where not needed
- File-Based — Researcher/Planner save to YAML files (not all in JSON output)
- Learnings — Empty patterns/conventions unless critical
Result: ~40-60% reduction on output tokens while maintaining quality.
- Design Agents — Dedicated agents for web and mobile UI/UX with anti-"AI slop" guidelines for distinctive aesthetics
- Mobile Agents — Native mobile implementation (React Native, Flutter) + iOS/Android testing
Raw reasoning isn't enough in single-pass chat. Gem-Team wraps your preferred LLM in a rigid harness with verification-first loops, fundamentally boosting its effective capability on SWE tasks.
Gem Team includes specialized design agents with anti-"AI slop" guidelines for distinctive, modern and unique aesthetics with accessibility compliance.
