docs

A documentation rule for adding a new commercetools API namespace tool, where a namespace groups related operations such as products.read or products.create. It covers researching the official API and updating the project's README and tool table.

In plain words
What is it for?
Use it when implementing a new commercetools namespace function, checking the official API documentation, and adding its operations to the README.
Why use it?
It gives developers a repeatable way to document new API operations and keeps the list of available tools up to date.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

97% identical to docs — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Creating a New namespace tool Function in @commercetools/commerce-agent

Updating the README.md file in the project root with the newly added feature or namespaces

This document outlines the steps taken to implement an updated README.md file by connecting to the official commercetools API.

The following steps are defining implementation of an example products.create. So the (namespace) here refers to product.

Implementation Steps

  1. Gather info regarding the (namespace)
  1. Define Available Tools In the ### Special Tool Options section of the Available Tools add to the end of the table the newly created or provided namespaces
    • Using the namespace fetched in previous step and complete the table like the example provided below using the product namespace

| products.read | Read product information | | products.create | Create product information | | products.update | Update product information |

  1. After updating the Available Tools table, ensure all the original formatting is maintained and do not add or carryout any other special editing or formatting.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docs is a cursor rule published in the GitHub repository commercetools/commerce-mcp (4 stars, last pushed 21d ago), licensed MIT. It adds 4 tokens to every session and 320 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to docs, differing in 2 lines, and is treated as a copy.
