Prompt Management
Centralized system prompts, templates, and format contracts—versioned, reviewed, and deployed without redeploying every agent
Exemplar
How this harness capability fits the Exemplar platform—governed agent operations, not a standalone prompt playground.
Why Exemplar
Prompt engineering alone cannot govern production agents—but ad-hoc prompts in every repo drift fast and are impossible to audit.
Exemplar separates prompt (instructions and format) from context (retrieval per turn) and harness (policy, tools, audit).
What Exemplar delivers
Managed prompt registry tied to agent types, orchestration steps, and evaluation suites.
Templates that compose with skills and live context instead of static mega-prompts.
How teams use it
Define base system prompts and output schemas in the harness console; roll forward with version tags.
Pair prompts with evals so prompt changes are gated on regression tests before production traffic.
