What it does

Writing Manual Test Cases is an agent skill from bitwarden/ai-plugins, published by the product's own GitHub organization. Use when authoring NEW manual test cases in Gherkin format from a feature description, Jira ticket, acceptance criteria, PR, or design doc — the kind a QA engineer imports into Testmo. Triggers on "write test cases for", "manual test cases", "Gherkin scenarios for this ticket", "test cases for Testmo", "what scenarios should we test for this feature". Produces a paired .txt and Testmo-importable .csv. Do NOT use it to write automated test code (NUnit, Jest, xUnit, Playwright), to inventory what tests already…

Its SKILL.md is about 1.9k 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 Unit testing. It works with Jira, Jest and Playwright. The repository describes itself as: AI plugin marketplace.

When your agent uses it

  • Authoring NEW manual test cases in Gherkin format from a feature description
  • Acceptance criteria
  • Design doc — the kind a QA engineer imports into Testmo
  • Write test cases for

Example prompts

  • “write test cases for”
  • “manual test cases”
  • “Gherkin scenarios for this ticket”
  • “/writing-manual-test-cases”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, Bash(gh pr view:*), Bash(gh pr diff:*), Skill(bitwarden-atlassian-tools:researching-jira-issues)

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Gap check — Using AskUserQuestion, ask for the top 3 critical pieces of information missing before test cases can be written (affected…
  2. Plan — Outline the scenario coverage as a bullet agenda: the areas to be covered and roughly how many cases each. Wait for approval. Write…
  3. Draft — Write the cases following the approved plan.
  4. Review — Pause and ask for feedback on clarity, tone, and completeness.
  5. Revise — Apply the notes. Repeat 3–4 until the user agrees the set is complete.
  6. Deliver — Write both output files (see Output files).

What it can do on your machine

Read from SKILL.md and the folder at commit 0e684b9. 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
    • Write
    • Glob
    • Grep
    • Bash(gh pr view:*)
    • Bash(gh pr diff:*)
    • Skill(bitwarden-atlassian-tools:researching-jira-issues)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Writing Manual Test Cases loads about 1.9k tokens when it runs. Until then it costs about 160 tokens; SKILL.md has 853 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~160
When it runs · the whole SKILL.md, loaded when a task matches
~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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 853 words (~1,886 tokens).

“Act as a Quality Assurance engineer and platform tester. Turn a feature's requirements into comprehensive, descriptive Gherkin test cases covering happy paths, negative cases, edge cases, and role/permission variations — written for other QA engineers in a formal, precise voice…”
