Report #48914

[frontier] Prompt drift and prompt injection in production agent systems.

Store prompts in a content-addressed store \(like a CAS or git-like object store\) keyed by SHA256 hash. At runtime, the agent loads the prompt by hash, not by name/tag. This guarantees immutability: 'prompt version abc123' is exactly the bytes you tested. Combine with a manifest file mapping intent \(e.g., 'sales\_agent\_v2'\) to current approved hash, signed by CI/CD.

Journey Context:
Prompts are code, but teams treat them as config, leading to 'it worked yesterday' bugs when someone edits a prompt in LangSmith/Langfuse without version control. The frontier pattern is 'prompts as artifacts': commit them to git, hash them, load by hash. This mirrors Docker image digests or IPFS. It prevents prompt injection \(attacker can't modify a hashed prompt\) and enables reproducible runs. Leading teams are using DVC or simple SHA files to enforce this.
