Symphony — OpenAI's First Agent Spec (WORKFLOW.md, SPEC.md)

What happened

OpenAI released Symphony — a spec/framework for building agents that operate over codebases. The key innovation: WORKFLOW.md and SPEC.md as machine-legible instruction files that agents use to navigate and operate within a codebase. This introduced 'harness engineering' as a vocabulary term — the discipline of building AI-legible instruction layers for codebases. 97M MCP installs; MCP donated to Linux Foundation (signal: standard protocol, not proprietary moat).

Why it matters for Seva's category

Symphony is the first signal that agentic infrastructure is standardizing. For AI GTM operators: this means AI agents can now reliably operate over company knowledge bases, CRMs, and workflow tools — not just coding environments. The WORKFLOW.md pattern (a file that tells agents how to operate in your context) is analogous to a 'context document for sales processes' — relevant to RevOps and GTM engineering teams thinking about AI-native workflows.
