What it does
Test Design Reviewer is an agent skill from citypaul/.dotfiles. Review test quality using Dave Farley's eight properties of good tests. Use when assessing a test file or suite for understandability, maintainability, repeatability, atomicity, necessity, granularity, speed, and evidence of test-first development.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/source-notes.md`).
It sits in Testing & QA, covering Test-driven development.
When your agent uses it
- Assessing a test file
- Suite for understandability
- Maintainability
- Evidence of test-first development
Example prompts
- “/test-design-reviewer”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Establish the claimed behavior, test layer, repository policy, and relevant risk.
- Read the tests without implementation and record what a failure would mean.
- Inspect the public production boundary, fixtures, and configured runner.
- Run focused tests or timing only when authorized and useful; report exactly what ran.
- Rate every property with evidence, including Not assessed where evidence is absent.
- Rank only actionable findings by severity and impact. Include the smallest credible fix.
- Separate test defects from production-design seams and local policy preferences.
What it can do on your machine
Read from SKILL.md and the folder at commit cd4028d. 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 (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
linkedin.com
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 Design Reviewer loads about 1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 425 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 425 words (~1,018 tokens).
“Review tests as executable specifications and safety evidence. Read the tests before the implementation so their public story can stand on its own, then inspect the production boundary and repository constraints needed to judge the claims accurately.”
