Cohere Error Diagnosis

Overview

Classify the failing layer before changing code, and return a minimal reproduction plus the safest next action.

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

• 400 and 422 usually indicate an invalid request contract or incompatible feature combination.
• 401 means the key is absent, invalid, expired, or injected into the wrong runtime.
• 402 indicates a billing limit; 429 indicates a current endpoint or model limit.
• Eligible 5xx and transport failures may be retried boundedly; deterministic client errors must not be retried.

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. Capture timestamp, endpoint, status, SDK version, resolved model, redacted request shape, and provider request identifier when available.
2. Check Cohere status and determine whether failures are global, model-specific, environment-specific, or request-specific.
3. Compare required v2 fields and feature combinations with the current reference.
4. Run one minimal non-sensitive reproduction with retries disabled.
5. Apply the smallest correction or mitigation and verify with one bounded probe.
6. Record the classification, evidence, correction, and rollback or escalation owner.

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

Examples

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

Input:

status=400; endpoint=/v2/embed; fields=model,texts,input_type; secret=redacted

Expected handoff:

cause=missing-embedding_types; retryable=false; fix=add-required-field
