What it does

Cohere Local Dev Loop is an agent skill from jeremylongshore/tons-of-skills-marketplace. Build a deterministic local Cohere development loop with a provider adapter, fixtures, and an opt-in live smoke test. Use when developing or testing Cohere features locally. Trigger with "Cohere local dev", "mock Cohere", or "Cohere test loop".

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 Testing & QA, covering QA and bug reports. 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

  • Testing Cohere features locally
  • With Cohere local dev
  • Cohere test loop

Example prompts

  • “Cohere local dev”
  • “mock Cohere”
  • “Cohere test loop”
  • “/cohere-local-dev-loop”

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. Locate the provider boundary and existing test framework before adding files.
  2. Define a narrow Cohere port for the operations the application actually needs.
  3. Add sanitized fixtures for success, rate limit, timeout, and malformed response paths.
  4. Write offline contract tests for request mapping, response parsing, and redaction.
  5. Add one opt-in live smoke test with a single request and hard timeout.
  6. Document the exact offline and live commands and ensure the default test command makes no network call.

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):

    • github.com
    • 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 Local Dev Loop 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 67 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
~67
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 Local Development Loop

Overview

Keep normal development offline and deterministic while preserving one tightly bounded path that proves the real v2 contract.

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

  • Mock the application-owned provider interface, not generated SDK internals.
  • Store representative v2 Chat, Embed, Rerank, stream, error, and tool-call fixtures with secrets removed.
  • Gate real calls behind an explicit environment switch and a protected evaluation key.
  • Treat model IDs and SDK response types as external contracts covered by adapter tests.

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. Locate the provider boundary and existing test framework before adding files.
  2. Define a narrow Cohere port for the operations the application actually needs.
  3. Add sanitized fixtures for success, rate limit, timeout, and malformed response paths.
  4. Write offline contract tests for request mapping, response parsing, and redaction.
  5. Add one opt-in live smoke test with a single request and hard timeout.
  6. Document the exact offline and live commands and ensure the default test command makes no network call.

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
Fixture driftRefresh from a redacted live response and review the diff.
Accidental spendFail closed unless the explicit live-test switch is set.
Flaky testReplace SDK/network dependence with the local provider port.
Secret in snapshotRevoke if real, scrub history, and add a regression assertion.

Examples

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

Input:

text
framework=vitest; default=offline; live-switch=COHERE_LIVE_TESTS

Expected handoff:

text
offline=pass; network-calls=0; live-smoke=opt-in; fixtures=sanitized
