SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams and developers design, evaluate, and improve agentic harnesses so systems avoid brittle tool-calling, weak permission models, unresolved workflow state, and missing evaluation plans that lead to unsafe or unmaintainable agent behavior.

Core Features & Use Cases

  • Architecture & Shape Selection: Recommend single-agent vs multi-agent patterns, subsystem boundaries, and transport/deployment considerations.
  • Tooling, Permissions & State: Define tool registries, approval gates, permission tiers, session durability, retry/idempotency policies, and state machines.
  • Evaluation & Observability: Produce evaluation plans, replayable evals, acceptance criteria, and observability/UX guidance to detect failures and regressions.
  • Use Cases: Designing a copilot with tool access, auditing an existing agent runtime for gaps, or producing a phased MVP and verification plan for a workflow orchestrator.

Quick Start

Use the n-agentic-harnesses-codex skill to design a lean, testable agentic harness for a tool-calling assistant that includes a tool registry, permission and approval policies, durable sessions with retry semantics, and an evaluation plan.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design an agentic harness with tool registries and permission gates?▼

Designing an agentic harness requires defining explicit subsystem boundaries, tool registries, and permission tiers to prevent unsafe tool-calling. You establish approval gates and state machines to ensure the agent runtime operates safely and maintainably.

What is an agentic harness and when do I need workflow state machines?▼

An agentic harness manages agent runtime behavior, requiring workflow state machines when orchestrating complex, multi-step tasks. You need this architecture to handle unresolved workflow states and ensure durable sessions during automated tool-calling operations.

How to evaluate agent runtime failures and set up replayable evals?▼

Evaluating agent runtime failures involves producing evaluation plans, replayable evals, and acceptance criteria to detect regressions. You implement observability guidance to monitor the agentic harness and verify that permission policies and tool registries perform correctly.

Can I use a single-agent architecture for a tool-calling assistant or do I need multi-agent patterns?▼

You can use single-agent or multi-agent patterns for a tool-calling assistant depending on your subsystem boundaries. Selecting the right architecture shape ensures the agentic harness remains lean, solo-maintainable, and effectively manages workflow state machines.

What's the best way to audit an existing agent runtime for permission and state gaps?▼

Auditing an existing agent runtime involves evaluating its permission policies, approval gates, and session durability against expected subsystem boundaries. You verify retry semantics and context assembly to identify gaps causing unmaintainable or unsafe agent behavior.

Why does my agent runtime lose state during retries and how do I implement session durability?▼

Agent runtime loses state during retries when session durability and idempotency policies are missing from the agentic harness. You implement durable sessions and explicit retry strategies to maintain workflow state machines and prevent unresolved task failures.
