cohere-migration-deep-dive
Migrate an application to or from Cohere with a provider adapter, parallel embedding index, quality evaluation, canary traffic, and rollback. Use when changing model providers. Trigger with "migrate to Cohere", "replace OpenAI with Cohere", or "Cohere replatform".
Why this skill is useful
Adds executable scripts for migrating LLM integrations and embeddings, which are not commonly found in public documentation.

What this skill does
Cohere Provider Migration Overview Treat provider migration as a semantic and operational change, not a search-and-replace of SDK calls. Prerequisites The target repository, runtime, environment, and accountable owner An approved Cohere team and key for any live verification Current quality, security, privacy, capacity, and change-control requirements Tool Discipline Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current Cohere primary documentation. Use Write or Edit only when the user requested implementation and the exact target files are known; never write credentials or customer content. Current Contract Cohere offers native v2 SDKs and an OpenAI compatibility API, but the compatibility surface omits Cohere-specific features. Chat messages, tool schemas, citations, safety controls, usage fields, errors, and stream events require explicit mapping. Embedding model changes require a parallel index because vectors from different contracts are not interchangeable. Model identifiers, limits, prices, and availability must be resolved for the target environment. Authentication Use an environment-specific key injected from an approved secret manager. Never print, persist, commit, or place COAPIKEY in an example. Confirm access with the least costly bounded operation appropriate to the task, and treat key creation, rotation, revocation, role changes, and production-capacity requests as owner-approved actions. Instructions 1. Inventory provider calls, prompts, tools, embeddings, indexes, streaming, errors, budgets, and user-visible quality. 2. Define a provider-neutral application port and golden evaluation set before implementing the target adapter. 3. Map supported semantics and record every incompatibility, especially citations, tools, safety, and structured output. 4. Build a parallel target embedding index with versioned model and dimension metadata. 5. …
