What it does

Agent QA Authoring is an agent skill from vostride/agent-qa. Use when creating, editing, validating, or running agent-qa tests, suites, or hooks. Prefer agent-qa MCP tools, enforce canonical agent-qa IDs, and use the bundled schema reference to avoid hallucinated config keys or YAML fields.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/agent-qa-contracts.json`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, OpenAI and Playwright. The repository describes itself as: Open-source self-improving QA agent for software teams. A test harness with memory. Write tests in natural language for web and mobile. agent-qa learns from every run, adapts to…

When your agent uses it

  • Running agent-qa tests
  • Tasks that involve MCP servers

Example prompts

  • “/agent-qa-authoring”

Requirements

  • Node.js

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Discover the local surface with agent_qa_discover.
  2. Inspect active config with agent_qa_get_config, especially targets, devices, providers, and services.mcp.
  3. Load references/agent-qa-contracts.json when you need exact schema fields or ID contracts.
  4. Generate every new ID with agent-qa tooling
  5. Never hand-write IDs. Validate existing IDs with agent_qa_validate_id or agent-qa ids validate --json.
  6. Validate definitions before saving
  7. Prefer MCP authoring mutations
  8. Use CLI/YAML fallback only when MCP is unavailable. Keep file paths matched by workspace.testMatch or workspace.suiteMatch.

What it can do on your machine

Read from SKILL.md and the folder at commit 22636e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent QA Authoring loads about 569 tokens when it runs, and up to ~891 if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 213 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~569
With references · SKILL.md plus every file in references/, read only if the agent opens them
~891

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 213 words (~569 tokens).
