What it does

Testcase Writer Plus is an agent skill from naodeng/awesome-qa-skills. Use this skill when you need high-quality test cases from requirements and analysis artifacts; triggers include testcase writer plus and advanced test case writing.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 36 other files, including scripts and reference files (for example `README.md`, `agents/openai.yaml` and `evals/cases/basic-success.yaml`).

When your agent uses it

  • You need high-quality test cases from requirements and analysis artifacts
  • Triggers include testcase writer plus and advanced test case writing

Example prompts

  • “/testcase-writer-plus”

Workflow steps

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

  1. Read and follow the main prompt listed under Progressive disclosure (coverage, structure, quality bar).
  2. Add only project context that changes the result: scope, environment, constraints, risks, dependencies, expected deliverable.
  3. If input is incomplete, return a usable first draft and explicitly mark assumptions and gaps.
  4. Default to Markdown; switch formats only when the user asks.

What it can do on your machine

Read from SKILL.md and the folder at commit 52c4eaf. 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

    Ships 1 file in scripts/, which the agent can run.

    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 no API keys, tokens, secrets or passwords.

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

Context cost

Testcase Writer Plus loads about 631 tokens when it runs, and up to ~755 if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~631
With references · SKILL.md plus every file in references/, read only if the agent opens them
~755

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); the scripts in this folder 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 297 words (~631 tokens).

“Chinese version: See the corresponding Chinese skill.”
