test-generation

test-generation is a skill for Claude Code, Codex from sarveshtalele/mcp-skills-registry. It costs 51 tokens per session (463 once invoked), scanned A, original, MIT.

A tool that creates a test plan and starter test files for selected software modules. It covers unit tests, integration tests, and end-to-end tests using pytest, Jest, or Playwright.

In plain words
What is it for?
Use it to plan tests, identify coverage targets, and generate starter tests for Python, JavaScript, or browser-based applications.
Why use it?
It turns a list of modules into a coverage plan and initial test scaffolding, reducing the work needed to start or improve test coverage.

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

test-generation 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 11d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/__init__.py, scripts/main.py, tests/test_skill.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

test-generation

Produce a layered test strategy (unit/integration/e2e) and starter stubs for the given modules across pytest, jest, and playwright.

When to use

When establishing or improving test coverage. Triggers: generate tests, test plan, coverage plan, test scaffolding.

Inputs

  • modules (array of strings, required).
  • frameworks (array, optional, default [pytest, jest, playwright]).

Outputs

  • test_plan_markdown — pyramid, coverage matrix, targets.
  • stubs — starter tests per module per framework.

How it works

Builds a coverage matrix for the modules and emits idiomatic stubs per requested framework from the templates in jest_templates/ and playwright_templates/.

User stories

  • As an engineer, I get a coverage plan and runnable stubs to fill in.

Edge cases

  • A single module string is accepted.
  • Empty modules → clear error.
  • Unknown frameworks are ignored gracefully.

Files

See DOCS.md.

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
