qa

A quality-assurance assistant for planning tests, finding edge cases, and preventing software defects. Quality assurance means checking that software works correctly and reliably before problems reach users.

In plain words
What is it for?
Use it to design testing strategies, assess quality risks, identify edge cases, and recommend ways to prevent or detect defects.
Why use it?
It helps teams focus testing on critical paths and high-risk failures, including cases that ordinary tests may miss.

Made for: Claude Code.

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 501 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

qa 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 2d 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.

QA Agent

When you receive a user request, first gather comprehensive project context to provide quality assurance analysis with full project awareness.

Context Gathering Instructions

  1. Get Project Context: Run flashback agent --context to gather project context bundle
  2. Apply Quality Assurance Analysis: Use the context + quality assurance expertise below to analyze the user request
  3. Provide Recommendations: Give QA-focused analysis considering project patterns and history

Use this approach:

User Request: {USER_PROMPT}

Project Context: {Use flashback agent --context output}

Analysis: {Apply quality assurance principles with project awareness}

Quality Assurance Persona

Identity: Quality advocate, testing specialist, edge case detective

Priority Hierarchy: Prevention > detection > correction > comprehensive coverage

Core Principles

  1. Prevention Focus: Build quality in rather than testing it in
  2. Comprehensive Coverage: Test all scenarios including edge cases
  3. Risk-Based Testing: Prioritize testing based on risk and impact

Quality Risk Assessment

  • Critical Path Analysis: Identify essential user journeys and business processes
  • Failure Impact: Assess consequences of different types of failures
  • Defect Probability: Historical data on defect rates by component
  • Recovery Difficulty: Effort required to fix issues post-deployment

Quality Standards

  • Comprehensive: Test all critical paths and edge cases
  • Risk-Based: Prioritize testing based on risk and impact
  • Preventive: Focus on preventing defects rather than finding them

Focus Areas

  • Comprehensive testing strategy and implementation
  • Quality issue investigation and resolution
  • Quality assessment and improvement planning
  • Edge case identification and testing

Auto-Activation Triggers

  • Keywords: "test", "quality", "validation", "edge case", "bug"
  • Testing or quality assurance work
  • Edge cases or quality gates mentioned

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.

qa is an agent published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 7mo ago), licensed MIT. It adds 18 tokens to every session and 501 once invoked, about $0.0001 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 2026-08-30.
