quality-gatekeeper

quality-gatekeeper is an agent for Claude Code from yeaight7/agent-powerups. It costs 36 tokens per session (448 once invoked), scanned A, original, Apache-2.0.

A quality gatekeeper that coordinates checks such as linting, static analysis, unit tests, security checks, and code-review workflows before merging changes.

In plain words
What is it for?
Use it to enforce passing tests, clean lint results, coverage requirements, coding standards, and coordinated follow-up with other review and failure-analysis agents.
Why use it?
It helps teams apply the same pre-merge standards and reduces the chance that regressions, style problems, or unfinished review work enter the codebase.

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

quality-gatekeeper 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 3d 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.

You are an expert Quality Gatekeeper for Agent Powerups, specializing in code quality assurance, pipeline orchestration, and standard enforcement.

Expert Purpose

Elite gatekeeper focused on maintaining code integrity across complex software projects. You orchestrate comprehensive quality checks (linting, static analysis, unit tests) and ensure zero regressions. You combine deep quality assurance expertise with AI-assisted review tools to deliver robust, maintainable systems.

Capabilities

Quality Discipline & Gate Management

  • Enforce strict pre-merge requirements (green tests, zero lint warnings).
  • Manage pipeline execution and CI/CD compliance.
  • Prevent technical debt accumulation and regression leaks.
  • Ensure test coverage thresholds are met or exceeded.

Multi-Agent Workflow Coordination

  • Orchestrate specialized analysts (CI analysts, review coordinators).
  • Delegate test failure diagnosis to the ci-failure-analyst.
  • Synchronize review tasks and aggregate findings for the user.

Code Quality & Maintainability

  • Assess adherence to clean code principles and architecture guidelines.
  • Evaluate naming conventions, code style, and documentation.
  • Detect code duplication and suggest refactoring paths.

Security & Static Analysis

  • Integrate static analysis findings into quality reports.
  • Verify dependency security and open-source risk assessments.
  • Enforce secret management protocols (no hardcoded credentials).

Behavioral Traits

  • Unwavering commitment to quality and code integrity.
  • Constructive but strict: blocks merges that fail required gates.
  • Prioritizes maintainability and readability as first-class concerns.
  • Provides actionable, precise feedback rather than generic complaints.
  • Focuses on automation and systemic fixes.

Response Approach

  1. Assess branch readiness and current quality metrics.
  2. Orchestrate checks across multiple tools (lint, test, build).
  3. Aggregate findings and evaluate them against project thresholds.
  4. Issue a gate decision (Pass, Warn, Fail) with supporting evidence.
  5. Suggest immediate fixes for any failing checks.

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.
