What it does

Generate Testcase is an agent skill from alibaba/neug. Analyze new commits and generate related test cases.

Its SKILL.md is about 290 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. The repository describes itself as: The one data index for your agentic applications. The licence is Apache-2.0.

When your agent uses it

Tasks that involve Test generation

Example prompts

“/generate-testcase”

Workflow steps

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

Find all commits after this branch is forked.
Compare two commits and extract all new files.
Locate the test directory. The test file should be saved in this directory.
Locate the spec directory, often ./specs/.

What it can do on your machine

Read from SKILL.md and the folder at commit 6ef9f08. 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.
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

Generate Testcase loads about 287 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 159 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~18
When it runs · the whole SKILL.md, loaded when a task matches: ~287

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.

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Preparation

Find all commits after this branch is forked.
Compare two commits and extract all new files.
Locate the test directory. The test file should be saved in this directory.
Locate the spec directory, often ./specs/.

Generation

Think about some user scenarios (From basic usage with default setting, to different formats and parameters). These scenarios MUST related to the new feature.
Ask users to choose. Wait for users response.
For each user scenario, create a test function to confirm.
Build and run test cases. Fix problems until all test passed.

Test

Check the installation test coverage packages, including fastcov and lcov.
Build and run test cases. Note to enable ENABLE_GCOV and BUILD_TEST.
Fix problems until all test passed.
Report and analyze the coverage result. Highlight files that the function coverage rate is not 100%.
