What it does
Writing Tests is an agent skill from maread99/market_prices. Instructions and guidance on writing tests
Its SKILL.md is about 320 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. It works with Python, pandas, yfinance and Bitcoin. The repository describes itself as: Get meaningful OHLCV datasets. The licence is MIT.
When your agent uses it
- Testing & QA work in your project
Example prompts
- “Use the writing-tests skill to instruction and guidance on writing tests. An agent skill from maread99/market_prices”
- “/writing-tests”
What it can do on your machine
Read from SKILL.md and the folder at commit abfb3cb. 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
Writing Tests loads about 315 tokens when it runs. Until then it costs about 14 tokens; SKILL.md has 180 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.

- writing-tests
- description
- Instructions and guidance on writing tests
Location
- tests are in
tests/. - doctests can be used instead of unit tests if the doctest fully covers the function/method's functionality.
- fixtures shared by the whole suite are located in
tests/conftest.py; fixtures shared by the tests of one package are located in theconftest.pyof that package's test directory.
Framework
- tests should assume use of the
pytestframework. - use appropriate features of the
pytestframework, to include fixtures and mocking. - a fixture that returns a class is named in CapWords, as a class is; every other fixture is named in snake_case.
Creating Test Datasets
- define test data to include values at the limits of where the output of tested functions/methods changes.
Writing tests
- tests should be written to test the INTENDED implementation with a focus on finding bugs.
- NEVER assume that the implementation is correct and that a test should pass.
- always test on and either side of limits where output changes.
- always seek to identify and test edge cases.
Documentation
- if including a docstring for a test then docstring should start with an imperative, for example 'Verify' or 'Test'.
