Harness engineering for AI products
Your AI feature shipped.Now harden the harness.
Progressical diagnoses where production LLM features lose signal, rebuilds the parts that matter, and leaves your team with an eval set, a PR, and a harness it can keep extending.
Audit-first access
Start with the layeryour users actually experience.
Progressical works on the harness around your LLM: retrieval, prompt assembly, conversation memory, tools, validation, retries, and fallbacks. Join the list for early audit availability.
Drop your work email. We use the list for audit availability and practical notes on production LLM harnesses.
Harness audit
Two weeks of trace review, failure-mode taxonomy, and a prioritized fix list for the LLM feature that matters most.
Rebuild as a PR
Retrieval, prompt assembly, memory, validation, and fallback changes delivered inside your codebase.
Eval set included
A scored set of real production cases so your team can measure model swaps and prompt changes before users do.
