cohere-hello-world
Run bounded Cohere v2 Chat, Embed, or Rerank requests with current model discovery and explicit validation. Use when proving a new Cohere setup. Trigger with "Cohere hello world", "Cohere quickstart", or "test Cohere API".
Why this skill is useful
Provides specific examples of using the Cohere API v2 for chat, embedding, and reranking that the AI wouldn't reliably generate on its own.
What it needs
Requires cohere-ai installed locally. Requires cohere account access. About 2k tokens when loaded. Last updated 2026-08-07. 2,604 stars on the source repository.
What this skill does
Cohere Bounded First Request Overview Prove one selected endpoint end to end while keeping model choice, input type, output bounds, and evidence explicit. 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 Discover a live model for the intended endpoint before pinning it. Chat v2 accepts a messages array and returns content under the response message. Embed v2 requires inputtype and embeddingtypes; use searchdocument for indexed passages and searchquery for queries. Rerank v2 orders supplied documents; select rerank-v4.0-pro for quality or rerank-v4.0-fast for measured latency needs. 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. Confirm authentication with cohere-install-auth and choose exactly one endpoint. 2. Resolve a live model from the catalog or Models API and record the resolved ID. 3. Use a non-sensitive, tiny fixture and set explicit output or result bounds. 4. Issue one v2 request and capture status, latency, model, billed-unit metadata when available, and response shape. 5. Validate non-empty Chat content, expected embedding dimensions, or monotonic Rerank ordering. 6. Return the minimal reproducible request with credentials redacted. …
