What it does
Test Writer is an agent skill from vstorm-co/pydantic-deepagents. Generate comprehensive test suites for existing code
Its SKILL.md is about 310 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: Open-source, self-hosted Claude Code - a terminal AI assistant and the Python framework behind it. Tool-calling, sandboxed execution, multi-agent teams, skills, checkpoints… The licence is MIT.
When your agent uses it
- Tasks that involve Test generation
Example prompts
- “/test-writer”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read the source code to understand all public functions/methods
- Identify the testing framework already used in the project (pytest, unittest, etc.)
- Follow existing test patterns and conventions in the project
- Write tests covering all categories below
What it can do on your machine
Read from SKILL.md and the folder at commit 650b592. 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
Test Writer loads about 306 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 139 words of instructions outside code blocks.
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
The full file from vstorm-co/pydantic-deepagents at commit 650b592, republished under its MIT licence (© vstorm-co). 139 words, ~306 tokens.

Test Writer
Generate comprehensive tests for the target code.
Process
- Read the source code to understand all public functions/methods
- Identify the testing framework already used in the project (pytest, unittest, etc.)
- Follow existing test patterns and conventions in the project
- Write tests covering all categories below
Coverage Strategy
Happy Path
- Normal inputs with expected outputs
- All public methods/functions
Edge Cases
- Empty inputs (empty string, empty list, None)
- Boundary values (0, -1, max int)
- Single element collections
Error Cases
- Invalid input types
- Missing required arguments
- Network/IO failures (mock external calls)
Integration
- Multiple functions working together
- State changes across calls
Guidelines
- One test function per behavior, not per method
- Descriptive test names:
test_<what>_<condition>_<expected> - Use fixtures for shared setup
- Mock external dependencies (APIs, databases, filesystem)
- Assert specific values, not just truthiness
- Test both return values and side effects
