What it does
Cohere Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Migrate Cohere API v1 or older SDK usage to v2 with contract tests, model lifecycle checks, canarying, and rollback. Use when upgrading Cohere dependencies or endpoints. Trigger with "Cohere v1 to v2", "upgrade Cohere SDK", or "Cohere deprecation".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live verification requires network access and an approved Cohere API key
It sits in DevOps & Cloud, covering Integration testing. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Upgrading Cohere dependencies
- With Cohere v1 to v2
- Upgrade Cohere SDK
- Cohere deprecation
Example prompts
- “Cohere v1 to v2”
- “upgrade Cohere SDK”
- “Cohere deprecation”
- “/cohere-upgrade-migration”
Requirements
- A credential in CO_API_KEY
- Compatibility (from SKILL.md): Designed for Claude Code; live verification requires network access and an approved Cohere API key
- Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Inventory SDK versions, endpoints, parameters, models, stream events, connectors, fine-tunes, and response parsing.
- Read the current migration and deprecation pages and classify each dependency as live, legacy, deprecated, or shut down.
- Add golden contract tests around current user-visible behavior and failure paths.
- Introduce the v2 client and provider adapter while retaining a feature-flagged rollback path.
- Migrate request and response shapes, then reindex embeddings if their model contract changes.
- Canary representative traffic, compare quality and operations, and remove v1 only after rollback criteria remain clear.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepWebFetchWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.cohere.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
CO_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Designed for Claude Code; live verification requires network access and an approved Cohere API key
From compatibility in the SKILL.md frontmatter.
Context cost
Cohere Upgrade Migration loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 450 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cohere API and SDK Upgrade
Overview
Inventory legacy behavior, move through the documented v2 contract, and prove semantic parity before removing rollback paths.
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
- V2 uses
messagesinstead of separate message, preamble, and managed conversation history fields. - V2 requires explicit models; Embed also requires embedding types.
- V2 tools use JSON Schema and correlate results with tool-call IDs.
- Legacy Generate, Summarize, Classify, managed connectors, selected models, and fine-tuning paths appear on Cohere's deprecation schedule.
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
- Inventory SDK versions, endpoints, parameters, models, stream events, connectors, fine-tunes, and response parsing.
- Read the current migration and deprecation pages and classify each dependency as live, legacy, deprecated, or shut down.
- Add golden contract tests around current user-visible behavior and failure paths.
- Introduce the v2 client and provider adapter while retaining a feature-flagged rollback path.
- Migrate request and response shapes, then reindex embeddings if their model contract changes.
- Canary representative traffic, compare quality and operations, and remove v1 only after rollback criteria remain clear.

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 |
|---|---|
| Missing v2 feature | Use an application-owned tool or retain a time-bound v1 path if still supported. |
| Embedding drift | Build a parallel index and cut over atomically. |
| Stream parser fails | Update from legacy text events to typed v2 events. |
| Quality regression | Stop the canary and preserve the old model path. |
Examples
Use this compact handoff shape to keep the selected scope, validation evidence, and operational result reviewable.

from=Client-v1; to=ClientV2; endpoints=chat,embed; canary=10%Expected handoff:
