Tracking AI prompts is a nightmare. So we built an open-source Prompt Bill of Materials (PBOM)

If you are building AI applications in production, you already know the dirty secret: prompt management is a mess

What starts as a clean system prompt quickly turns into a tangled web of hardcoded strings, tweaked parameters, and fragmented version histories. When an AI feature suddenly starts hallucinating or fails a security check, tracing the exact combination of the prompt, model version, and temperature that caused the issue is incredibly painful.

In traditional software, we solved supply-chain chaos with the SBOM (Software Bill of Materials).

AI needs the exact same thing. That is why we are open-sourcing the PBOM (Prompt Bill of Materials) Specification.

🧩 Enter the PBOM

EqoAI/pbom-spec is an open-source standard designed to track, version, and secure the lifecycle of AI prompts.

Just like an SBOM tells you exactly which open-source libraries are running in your application, a PBOM provides a machine-readable ledger of your AI supply chain. It acts as a standardized contract that describes the components of an AI prompt system.

What does it look like?

Instead of guessing what went into a production AI call, a PBOM gives you a structured, verifiable manifest. Here is a conceptual look at how you can standardize a prompt's footprint:

  },

      "parameters": {
        "temperature": 0.7,
        "max_tokens": 500
      }
    },
    {
      "type": "prompt_template",
      "id": "customer-support-v2",
      "hash": "sha256:8f434346648f...",
      "dependencies": ["user_context_module"]
    }
  ]
}
