At a glance

Run the backend test suite correctly — working directory, Docker requirement, single-test vs full-suite commands.

  • Writing backend tests in apps/backend
  • Calls uv
  • Tasks that involve Test generation
  • Tasks that involve Containers

What it does

Backend Testing is an agent skill from rhesis-ai/rhesis. Run the backend test suite correctly — working directory, Docker requirement, single-test vs full-suite commands. Use when running or writing backend tests in apps/backend.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test generation and Containers. It works with Docker. The repository describes itself as: The collaboration layer for AI teams: domain experts annotate and review agent behavior, engineers improve the agent from what they find.

When your agent uses it

  • Writing backend tests in apps/backend
  • Tasks that involve Test generation
  • Tasks that involve Containers

Example prompts

  • “/backend-testing”

Requirements

  • Docker

What it can do on your machine

Read from SKILL.md and the folder at commit 1a2c578. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Backend Testing loads about 400 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~400

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 163 words (~400 tokens).

“Ask the user before running the whole backend suite. It takes a very long time. Default to the narrowest selection that covers the change (single test, class, or file); only run ../../tests/backend/ in full once the user says to.”
