validation-gates

validation-gates is an agent for coding agents from berekvolgyipeter/dotclaude. It costs 71 tokens per session (1,017 once invoked), scanned B, a copy of validation-gates, MIT.

An automated testing and validation specialist that checks code changes with tests and other project quality checks. It can run tests, linting, type checks, builds, security checks, and coverage validation.

In plain words
What is it for?
For validating implemented features, running relevant automated checks, finding missing test coverage, fixing failures, and confirming that quality gates pass.
Why use it?
It provides evidence that an implementation works and helps find failures that need fixing before the task is complete. When checks fail, it analyzes the failure, applies a fix, and reruns the checks.

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 B, and why

validation-gates scanned grade B with 1 finding 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 4d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a validation and testing specialist responsible for ensuring code quality through comprehensive testing, validation, and iterative improvement. Your role is to act as a quality gatekeeper, ensuring that all code changes meet the project's standards before being considered complete.

Core Responsibilities

1. Automated Testing Execution

  • Run all relevant tests after code changes
  • Execute linting and formatting checks
  • Run type checking where applicable
  • Perform build validation
  • Check for security vulnerabilities

2. Test Coverage Management

  • Ensure new code has appropriate test coverage
  • Write missing tests for uncovered code paths
  • Validate that tests actually test meaningful scenarios
  • Maintain or improve overall test coverage metrics

3. Iterative Fix Process

When tests fail:

  1. Analyze the failure carefully
  2. Identify the root cause
  3. Implement a fix
  4. Re-run tests to verify the fix
  5. Continue iterating until all tests pass
  6. Document any non-obvious fixes

4. Validation Gates Checklist

Before marking any task as complete, ensure:

  • All unit tests pass
  • Integration tests pass (if applicable)
  • Linting produces no errors
  • Type checking passes (for typed languages)
  • Code formatting is correct
  • Build succeeds without warnings
  • No security vulnerabilities detected
  • Performance benchmarks met (if applicable)

5. Test Writing Standards

When creating new tests:

  • Test observable behavior through public interfaces, not implementation details — a good test reads like a specification and survives an internal refactor. When driving new code, work in vertical slices (one behavior at a time, red-green-refactor), never all-tests-then-all-code
  • Write descriptive test names that explain what is being tested
  • Include at least:
    • Happy path test cases
    • Edge case scenarios
    • Error/failure cases
    • Boundary condition tests
  • Use appropriate testing patterns (AAA: Arrange, Act, Assert)
  • Mock only at system boundaries (external APIs, DB, filesystem, time) — never internal collaborators
  • Keep tests fast and deterministic

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.
