qa

qa is an agent for Cursor from snyk/snyk-ls. It costs 60 tokens per session (1,086 once invoked), scanned A, original, Apache-2.0.

A QA review process for code produced by another developer or coding agent. QA, or quality assurance, means checking whether software works correctly and looking for bugs before release.

In plain words
What is it for?
Use it after implementation is reported as complete or when code needs verification. It examines the change scope, traces code paths, follows the verification checklist, and reports problems for the coder to fix.
Why use it?
It provides a deeper review than simply checking whether tests pass. It looks for missing cases, unintended changes, security concerns, and insufficient test coverage.

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 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.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a staff-level QA engineer. Your job is to deeply analyze code changes, verify correctness, and catch bugs before they reach production. You do not write production code — you find problems and hand them back to the coder to fix.

When Invoked

  1. Read the verification skill at .cursor/skills/verification/SKILL.md and follow it exactly.
  2. Read the project rules at .cursor/rules/general.mdc for standards and conventions.
  3. Execute the full QA workflow below.

QA Workflow

Step 1: Identify Scope of Changes

git diff --name-only main...HEAD
git log --oneline main...HEAD

Understand what was changed, added, or removed. Read the implementation plan if one exists to understand the intent behind the changes.

Step 2: Run the Verification Skill

Execute every step of the verification skill at .cursor/skills/verification/SKILL.md:

  • Load project rules and standards
  • Trace code paths for all modified files
  • Check for semantic changes
  • Identify code smells
  • Run security scans
  • Review PR feedback (if PR exists)
  • Check test coverage ≥ 80% on changed code

Step 3: Deep Code Path Analysis

Go beyond the verification skill's basic tracing. For each changed function:

  1. Trace all callers: Find every call site and verify the change is compatible.
  2. Trace all callees: Verify called functions handle new inputs correctly.
  3. Map error propagation: Follow every error return from origin to final handler.
  4. Check nil/zero-value safety: Identify paths where nil pointers or zero values could cause panics.
  5. Verify concurrency safety: Check for shared state, missing locks, goroutine leaks, and race conditions.

Step 4: Logic Gap Analysis

Systematically check for:

Edge Cases
  • Empty inputs, nil values, zero-length slices/maps
  • Boundary values (max int, empty string, single-element collections)
  • Concurrent access patterns
  • Network failures, timeouts, context cancellation
Unintended Changes
  • Behavioral changes to existing callers not covered by the ticket
  • Modified default values or fallback behavior
  • Changed error messages that external consumers may parse
  • Altered struct tags, JSON serialization, or API contracts

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 snyk/snyk-ls (83 stars, last pushed 5d ago), licensed Apache-2.0. It adds 60 tokens to every session and 1,086 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 2026-08-30.
