What is Nexus
A terminal-first aggregator that curates installable engineering skills and specialist agents into one automation layer.
Agents
Specialized workers for architecture, debugging, planning, and operations.
Skills
Reusable execution intelligence for repeatable engineering outcomes.
Token Management
Built-in token-saving strategy for cost-aware and context-efficient execution.
Orchestration
Context-aware handoffs between agents running in sequence or parallel.
Tooling
MCP integrations across GitHub, Jira, AWS, Slack, and more.
Memory
Long-lived context, TODO intelligence, and cross-session continuity.
Skills Marketplace
Discover installable skills for architecture, security, testing, observability, and token management.
Architecture Mapper
Maps service boundaries, dependencies, and deployment risk before major changes.
/nexus:architecture map this monolith into bounded contexts
nexus skill install architecture-mapper
Autonomous Debugger
Runs evidence-first root-cause analysis with narrow fixes and verification loops.
/nexus:debugging fix production deployment issue
nexus skill install autonomous-debugger
PR Review Guardian
Performs senior-grade code reviews with severity-ranked findings and rollout risk.
/nexus:code-review review this PR for regressions
nexus skill install review-guardian
Refactor Strategist
Plans incremental refactors with dependency awareness and regression containment.
/nexus:planning refactor this service without downtime
nexus skill install refactor-strategist
DevOps Automator
Builds CI pipelines, release gates, and rollback-safe deployment workflows.
/nexus:reliability create release rollout workflow
nexus skill install devops-automator
Security Sentinel
Audits policies, permissions, and secrets exposure with least-privilege guidance.

nexus skill install observability-correlator
Performance Forensics
Investigates latency, memory, and CPU regressions with blast-radius analysis.
/nexus:performance optimize architecture for latency
nexus skill install performance-forensics
Test Stabilizer
Eliminates flaky tests using deterministic fixtures and race-condition isolation.
/nexus:testing investigate flaky tests
nexus skill install test-stabilizer
Token Management
Optimizes context usage, prompt shape, and delegation depth to reduce token spend.
