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 input_type and embedding_types; use search_document for indexed passages and search_query 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 CO_API_KEY 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.

Approval Boundaries

Do not expose or rotate keys, change Cohere Team roles, accept commercial terms, enable sensitive production data, increase spend or capacity, switch production models, send a support bundle, or execute model-proposed side effects without the accountable owner's approval. Keep diagnosis read-only unless implementation was requested.

Output

Return the resolved API and model contract, files or settings inspected, evidence collected, validation result, remaining risk, owner, and rollback or next action. Redact keys, authorization headers, prompts, retrieved documents, embeddings, customer identifiers, and unrestricted environment output.

Error Handling

| Condition | Response | |---|---| | 400 | Check required v2 fields and endpoint-specific input types. | | 401 | Re-run the read-only authentication probe. | | 404 model | Resolve an accessible live model instead of guessing an alias. | | 429 | Honor the endpoint limit and stop the smoke test. |

Examples

Use this compact handoff shape to keep the selected scope, validation evidence, and operational result reviewable.

Input:

text
endpoint=embed; input=two-public-sentences; model=resolve-live; max-requests=1

Expected handoff:

text
endpoint=embed-v2; model=resolved-id; vectors=2; validation=pass
