What it does

Cohere Core Workflow B is an agent skill from jeremylongshore/tons-of-skills-marketplace. Build a bounded Cohere v2 tool-use loop with JSON Schema, explicit dispatch, result correlation, and approval gates. Use when adding Cohere-powered agents or function calling. Trigger with "Cohere tool use", "Cohere agent", or "Cohere function calling".

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 AI & LLM Engineering, covering Structured output and tool calling. 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

  • Adding Cohere-powered agents
  • Function calling
  • With Cohere tool use
  • Cohere function calling

Example prompts

  • “Cohere tool use”
  • “Cohere agent”
  • “Cohere function calling”
  • “/cohere-core-workflow-b”

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.

  1. Define a minimal tool allowlist, strict schemas, timeouts, and side-effect classifications.
  2. Resolve a live tool-capable model and submit the user message plus tool definitions.
  3. Validate tool name, arguments, tenant scope, and approval state before dispatch.
  4. Execute read-only calls automatically only if policy allows; pause for consequential writes.
  5. Append correlated tool results and continue until content is returned or the iteration budget is exhausted.
  6. Test unknown tools, invalid arguments, duplicate calls, timeouts, denial, and loop exhaustion.

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:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    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 Core Workflow B 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 69 tokens; SKILL.md has 440 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

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 Tool-Using Agent Loop

Overview

Let the model propose typed tool calls while application code validates, authorizes, executes, correlates, and limits every side effect.

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

  • Define each v2 tool as a function with JSON Schema parameters.
  • Read proposed calls from the response message and correlate results with tool_call_id.
  • Append the assistant tool-call message and tool results to the application-managed messages history.
  • Command A+ was the current high-capability tool-use candidate on the review date; resolve availability before pinning it.

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. Define a minimal tool allowlist, strict schemas, timeouts, and side-effect classifications.
  2. Resolve a live tool-capable model and submit the user message plus tool definitions.
  3. Validate tool name, arguments, tenant scope, and approval state before dispatch.
  4. Execute read-only calls automatically only if policy allows; pause for consequential writes.
  5. Append correlated tool results and continue until content is returned or the iteration budget is exhausted.
  6. Test unknown tools, invalid arguments, duplicate calls, timeouts, denial, and loop exhaustion.

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

ConditionResponse
Unknown toolReturn a structured denial result; never dispatch by reflection.
Invalid argumentsReject before execution and preserve validation evidence.
Missing correlationStop because tool results cannot be safely attached.
Loop exhaustedReturn partial state and request direction without another model call.

Examples

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

Input:

text
goal=lookup-order; tools=read-only-order-status; max-iterations=4

Expected handoff:

text
iterations=2; tool-calls=1; side-effects=none; final=validated
