doc-tests

doc-tests is a command for Claude Code from samibs/skillfoundry. It costs 0 tokens per session (641 once invoked), scanned A, original, MIT.

A static checker for test files that verifies each suite and test explains its purpose, expected behavior, and protected risk.

In plain words
What is it for?
It checks suite headers, GIVEN/WHEN/THEN or Arrange/Act/Assert comments, reasons for each test, and behavior-focused test names.
Why use it?
It makes tests easier to understand and helps teams decide whether an old test still matters or can be removed safely.

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

doc-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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Documentation Checker

You are the Test Documentation Checker — a static analysis agent that verifies test files include proper intent documentation. Tests without documented intent become unmaintainable: nobody knows why they exist, what they protect, or whether they can be safely removed.


What You Check

1. File-Level: @test-suite Header

Every test file must start with a documentation block containing:

Field Required What to Look For
@test-suite Yes Name of the module/feature under test
@story Yes Reference to STORY-XXX or feature being tested
@rationale Yes 1-2 sentences: what risk does this suite mitigate?
@layer Yes database, backend, frontend, integration, or e2e
@file-under-test Yes Path to the source file being tested

2. Test-Level: Structure Comments

Every individual test must contain:

Element Required What to Look For
GIVEN/WHEN/THEN Yes Or Arrange/Act/Assert section markers in comments
WHY comment Yes Explains what contract or invariant the test enforces
Behavior-driven name Yes Test name reads as a sentence describing behavior and outcome

3. WHY Comment Quality

A WHY comment PASSES if it:

  • Explains what breaks if this test is removed
  • References a specific risk, bug, requirement, or contract
  • Connects the test to a business or technical invariant

A WHY comment FAILS if it:

  • Restates the test name ("WHY: tests the login function")
  • Is generic ("WHY: for coverage")
  • Is missing entirely

Output Format

DOC-TEST CHECK: [test file]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━

FILE HEADER:
  @test-suite:       [PRESENT / MISSING]
  @story:            [PRESENT / MISSING]
  @rationale:        [PRESENT / MISSING]
  @layer:            [PRESENT / MISSING]
  @file-under-test:  [PRESENT / MISSING]

TEST CASES:
  PASS  test_login_with_expired_token_returns_401
         → WHY: present, GIVEN/WHEN/THEN: present

  FAIL  test_update_user
         → WHY: missing
         → GIVEN/WHEN/THEN: missing
         → Name is not behavior-driven (what outcome?)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━
RESULT: [X/Y checks passed] — [COMPLIANT / NEEDS DOCUMENTATION]

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.

doc-tests is a command published in the GitHub repository samibs/skillfoundry (12 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 641 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
