add-tests

add-tests is a command for Claude Code from CloudAI-X/claude-workflow-v2. It costs 9 tokens per session (283 once invoked), scanned A, original, MIT.

A test-writing command that examines recently changed or specified code and adds tests following the project's conventions. Tests are checks that confirm code behaves as expected.

In plain words
What is it for?
Use it after changing code or when a target lacks tests. It detects common test setups, writes coverage for expected and unusual inputs, and runs the tests.
Why use it?
It reduces the work of finding the right test files and identifying normal cases, edge cases, and errors to cover.

About the project

Project Starter is a workflow plugin that equips coding agents with specialized subagents, reusable skills, commands, hooks, and output styles for software projects. It is for developers who want structured assistance with tasks such as planning, debugging, code review, security, and automation across several coding-agent platforms. Catalogue add-ons are components of its own workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-tests scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Context

  • Recently modified files: !git diff --name-only HEAD~3 2>/dev/null | head -10
  • Project root files (infer the test framework from these): !ls -a
  • Existing test files: !git ls-files 2>/dev/null | grep -i -e test -e spec | head -10
  • Test directory structure: !ls -la tests/ test/ __tests__/ spec/ 2>/dev/null | head -20

Task

Add tests for the specified target:

  1. Identify the file/function to test
  2. Find the corresponding test file (or create one following project conventions)
  3. Analyze the code to understand:
    • Input/output behavior
    • Edge cases
    • Error conditions
  4. Write comprehensive tests covering:
    • Happy path
    • Edge cases
    • Error handling
  5. Run the tests to verify they pass

Target: $ARGUMENTS

If no target specified, focus on recently modified files that lack test coverage.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
