What it installs

Skills (13)

  • adversarial-qa

    Autonomous Adversarial QA agent. Reads machine-readable specs and code to execute edge-case and security testing, returning a JSON verdict.

  • autonomous-orchestrator

    Sovereign loop manager. Handles file initialization, feature lifecycle tracking, and recursive TDD-Validation-Optimization cycles. Strictly delegates all technical tasks to sub-agents.

  • harness-evaluator

    Harness performance evaluator. Reads all execution traces in docs/harness-history/traces/, computes composite scores per skill_chain, identifies the Pareto frontier of best harness configurations, and recommends the optimal chain for the next session. Run periodically or on demand to guide harness o

  • harness-tracer

    Execution trace recorder. Captures what happened during a skill session and persists structured logs to docs/harness-history/traces/. Enables retrospective analysis and harness optimization via harness-evaluator and meta-harness.

  • memory-context

    Initialize and maintain a local multi-project Harness Memory cache, then use Harness Memory MCP efficiently for evidence-backed context, relationships, environment comparisons, and change impact.

  • meta-harness

    Autonomous Meta-Harness proposer. Reads the full harness history filesystem, diagnoses failure patterns, proposes a targeted improvement, stores the candidate, and outputs a JSON decision.

  • pbb-design

    Designs a Product Backlog using the Product Backlog Building (PBB) methodology from an initial product or feature scope.

  • project-memory

    Orchestrate sequential creation, updates, and evidence-backed consolidation of project documentation in docs/ and targeted root README.md edits. Use for documentation changes, scoped audits, and incremental memory maintenance.

  • qa-orchestrator

    Plan and run evidence-backed acceptance tests with the Harness Kit `hrns qa` CLI. Use when the user wants to install or use `@romabeckman/hrns`, define QA scope and scenarios, execute runtime QA against an application, or summarize a QA run. Do not use for unit-test-only requests or static code revi

  • read-ui-prototype

    UI/UX prototype reader. Analyzes interface prototypes (screens, Figma links, images, frames) and translates them into a structured, semantic, LLM-actionable frontend specification — without writing any code or inventing visual values. Output targets the developer-frontend agent.

  • scope-refinement

    DDD Scope Refinement Orchestrator — coordinates all Domain-Driven Design phases from business discovery to test scenario specification and machine-readable exports. Supports both interactive and autonomous headless execution.

  • tdd-orchestrator

    Orchestrates development workflow using Test-Driven Development (TDD) methodology. Coordinates between testing and development skills to ensure quality implementation. Guides the process from test creation to implementation, validation, and documentation updates, strictly following the project-speci

  • the-grumpy-tech-lead

    Senior Tech Lead and Software Architect specialized in technical code review with a focus on systemic impacts, security, performance, scalability, etc. Acts as a mentor using Socratic questioning to identify N+1 risks, memory leaks, race conditions, SOLID/DRY violations, and production failures with

Subagents (10)

  • cto

    Chief Technology Officer for business design and autonomous delivery governance. Routes product discovery through pbb-design before technical refinement or implementation.

  • developer-backend

    Senior Backend Developer specialized in TDD, API design, database modeling, security, and performance. Use for writing backend code (APIs, services, workers), fixing server bugs, implementing business logic, and backend testing.

  • developer-debugging

    Systematic Investigation and Debugging Specialist. Uses an evidence-driven workflow and the "5 Whys" to identify the root cause of bugs before implementation.

  • developer-devops

    Senior DevOps/Platform Engineer specialized in CI/CD pipelines, infrastructure as code, containerization, observability, and release automation. Use for pipeline implementation, Dockerfile/Compose/Helm authoring, IaC (Terraform, Pulumi), and deployment automation tasks.

  • developer-frontend

    Senior Frontend Developer specialized in TDD, UI/UX implementation, accessibility, and performance. Use for writing frontend code (React, Vue, CSS, HTML), fixing UI bugs, implementing designs, and frontend testing.

  • developer-qa

    Senior QA Engineer specialized in test strategy, automation, exploratory testing, and quality gates. Use for implementing test suites, writing E2E/contract/load tests, auditing test coverage, and establishing quality standards across the pipeline.

  • harness-qa

    Adversarial QA specialist for autonomous or independent review. Identifies concrete security, boundary, concurrency, integration, and behavioral defects and returns a structured JSON verdict.

  • harness-tech-lead

    Senior Tech Lead and Software Architect specialist for the autonomous-orchestrator pipeline. Evaluates systemic risks, scalability, security design, resilience, architecture boundaries, and maintainability. Returns a structured JSON verdict for Phase C Decision Gate evaluation.

  • meta-harness-agent

    Meta-Harness proposer agent. Reads the harness history filesystem (docs/harness-history/traces/, candidates/, pareto-frontier.md), diagnoses failure patterns across sessions, and proposes targeted improvements to existing skills. Implements the automated harness search loop described in the Meta-Har

  • software-architect

    Senior Software Architect specialized in DDD, system design, technical refinement, and technical decision-making. Use for architecture decisions, scope refinement, design refinement, and technical quality gates.
