A test-suite review tool that examines automated tests for weak checks and excessive use of mock objects, which stand in for real parts of an application. It uses code-structure analysis and several review stages to identify quality problems and can rewrite tests when required checks fail.

Use it to review test quality, find over-mocking, check tests before merging code, or add test-quality checks to a CI/CD pipeline, the automated build and verification process.

It helps find tests that pass without proving the real code works. This reduces false confidence caused by tests that only check mocked behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00064	$0.05337
Opus 5	$0.00032	$0.02669
Sonnet 5	$0.00013	$0.01067
Haiku 4.5	$0.00006	$0.00534

Security

Grade A, and why

test-audit 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 10d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/data-flow-analyzer.ts, scripts/integration-mock-detector.ts, scripts/skip-detector.ts, …), 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.

How it starts

The opening of the file, as written. The whole thing — 532 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Audit

User-facing entry point for test suite quality auditing. Orchestrates classification, mock detection, and synthesis stages to identify T1-T4 violations and trigger automatic rewrites when required.

When to Use This Skill

Load this skill when the user request matches ANY of these patterns:

Trigger Pattern	Example User Request
Test quality audit	"Audit my tests", "Check test quality", "Review test suite"
Mock detection	"Find mock violations", "Check for T1 violations", "Are my tests over-mocked?"
Test effectiveness	"How effective are my tests?", "Are my tests real or mocked?"
After writing tests	"I just wrote tests for X, can you audit them?"
CI/CD integration	"Add test audit to pipeline", "Validate tests before merge"

DO NOT use for:

Running tests (use npx jest (or your project test runner))
Writing new tests (implement directly)
General code review (use code-review skill)
Debugging test failures (use issue-debugging skill)

Pre-Flight Gate (BLOCKING)

STOP. Before ANY analysis, you MUST acknowledge what this skill requires.

This skill uses a multi-stage pipeline with sub-agents. You are the orchestrator, NOT the executor.

What You MUST Do

Run Stage 0 AST scripts before any LLM stages:
- npx tsx skills/test-audit/scripts/verification-counter.ts {target} → /tmp/claude/ast-verify-count.json
- npx tsx skills/test-audit/scripts/skip-detector.ts {target} → /tmp/claude/ast-skip-detect.json
- npx tsx skills/test-audit/scripts/data-flow-analyzer.ts {target} → /tmp/claude/ast-data-flow.json
Select mode based on file count and threshold (default 5)
Spawn sub-agents for each applicable stage:
- Stage 1 (Scale mode only): Classification → Task(subagent_type="general-purpose", model="haiku", ...)
- Stage 2: Mock Detection → Task(subagent_type="general-purpose", model="sonnet", ...)
- Stage 3: Synthesis → Task(subagent_type="general-purpose", model="sonnet", ...)

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.

test-audit is a skill published in the GitHub repository ashaykubal/essential-agents-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 64 tokens to every session and 5,337 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-31.
