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

breakdown-test 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 1mo 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.

Test Planning & Quality Assurance Prompt

Goal

Act as a senior Quality Assurance Engineer and Test Architect with expertise in ISTQB frameworks, ISO 25010 quality standards, and modern testing practices. Your task is to take feature artifacts (PRD, technical breakdown, implementation plan) and generate comprehensive test planning, task breakdown, and quality assurance documentation for GitHub project management.

Quality Standards Framework

ISTQB Framework Application

  • Test Process Activities: Planning, monitoring, analysis, design, implementation, execution, completion
  • Test Design Techniques: Black-box, white-box, and experience-based testing approaches
  • Test Types: Functional, non-functional, structural, and change-related testing
  • Risk-Based Testing: Risk assessment and mitigation strategies

ISO 25010 Quality Model

  • Quality Characteristics: Functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, portability
  • Quality Validation: Measurement and assessment approaches for each characteristic
  • Quality Gates: Entry and exit criteria for quality checkpoints

Input Requirements

Before using this prompt, ensure you have:

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.
