What are Agent Specifications?

The missing layer between product thinking and AI code generation. Learn what agent specs are, why they matter, and how they transform the way AI-native teams build software.

The problem: AI agents lack context

AI coding agents like GitHub Copilot, Claude Code, Cursor, and Devin are transforming software development. But there's a critical gap: these agents are only as good as the context they receive.

What happens without agent specs

  • Vague prompts like "build a settings page" produce generic, off-strategy features
  • AI agents don't know your product vision, strategic boundaries, or success criteria
  • Early adopter teams report spending hours per feature reworking AI-generated code that missed the point
  • No learning loop — the same context gaps repeat every sprint

Agent specifications: the solution

An agent specification is a structured, context-rich document designed specifically for AI coding agents. It includes everything an agent needs to implement a feature correctly on the first try:

Product Vision & Strategy

The strategic direction and guardrails that define acceptable solutions

Discovery Insights

Validated customer needs, risks assessed, and assumptions tested

OKR Success Criteria

Measurable outcomes the feature must drive, connected to team objectives

Implementation Context

Technical constraints, architecture patterns, API contracts, and coding standards

Acceptance Criteria

Precise, testable scenarios with edge cases and error handling

How agent specs work in practice

Agent specifications are generated from your existing product thinking \u2014 you don't write them from scratch.

1

Think

Define vision, validate strategy, run discovery, set OKRs

2

Generate

Delvyn Studio assembles all context into a structured agent spec

3

Push

Push to GitHub (Copilot), Linear (Claude Code), or sync to repo

4

Learn

Capture implementation learnings → future specs improve

Who needs agent specifications?

  • Product Leaders: Ensure AI agents build what you envisioned, not what they guessed
  • Engineering Managers: Reduce rework from vague requirements. Get it right the first time.
  • Teams using GitHub Copilot: Push context-rich issues that Copilot Agent can implement with strategic alignment
  • Teams using Claude Code / Devin: Create Linear tasks with full product context for AI agent delegation
  • Teams adopting Cursor: Sync specification context directly to repository instruction files
