The problem
What you're seeing
You want to switch (or add) Anthropic Claude for cost, quality, or vendor-risk reasons — but tool calls, system prompts, and streaming differ.
How we fix it
Our approach
We port the call sites, translate tool definitions, retune prompts for Claude's style, and verify with side-by-side evals before flipping traffic.
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Evaluation harness with scored test cases
Implementation behind feature flags + rollback plan
Cost & latency dashboard wired to your observability
Hand-off doc covering prompts, models, and guardrails
Tooling we use
Industry-standard stack, no proprietary lock-in
