What it does

Vscuse Case Diagnosis is an agent skill from OfficeDev/microsoft-365-agents-toolkit. Use when: running an existing vscuse test case, reproducing a failing vscuse plan, deciding product bug vs test plan drift vs setup failure vs flake, repairing a failing case with vscuse-ui/noVNC when useful, and finishing with vscuse CLI validation.

Its SKILL.md is about 4.1k 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. It works with Microsoft 365. The repository describes itself as: Developer tools for building Teams apps.

When your agent uses it

  • : running an existing vscuse test case
  • Reproducing a failing vscuse plan
  • Deciding product bug vs test plan drift vs setup failure vs flake
  • Repairing a failing case with vscuse-ui/noVNC when useful

Example prompts

  • “/vscuse-case-diagnosis”

Requirements

  • Docker

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Locate the Owning Case
  2. Prepare the Runtime and Select the Product Image
  3. Execute the Focused Plan
  4. Gather Failure Evidence
  5. Classify Before Editing
  6. Repair the Smallest Surface with vscuse-ui First
  7. Validate and Report

What it can do on your machine

Read from SKILL.md and the folder at commit c89a0dd. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are powershell).

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • M365_ACCOUNT_PASSWORD

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

Context cost

Vscuse Case Diagnosis loads about 4.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 2,108 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k

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 2,108 words (~4,097 tokens).
