What it does
Adversarial QA is an agent skill from inkline/inkline. Repro-first QA for Inkline — minimal .ink.tsx reproductions, the visual-parity and cross-target harnesses, fuzz targets, and how to audit teammates' claims. Use for bug verification, regression coverage, and claim audits.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering React components and Fuzzing. The repository describes itself as: Inkline is the intuitive UI Components library that gives you a developer-friendly foundation for building high-quality, accessible, and customizable Vue.js 3 Design Systems.
When your agent uses it
- Bug verification
- Regression coverage
Example prompts
- “/adversarial-qa”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Reproduce before believing. Compiler bug → the smallest .ink.tsx that shows it (+ target list); component bug → story id + framework(s) +…
- Reduce until every line is load-bearing. The repro IS the test: a compiler fixture under fixtures/ + scenario assertion, a per-target…
- Bisect when the regression window is known (git bisect with the repro script). Rebuild core/compiler dist (vp pack) per step — consumers…
- For "fixed" claims: check out the fix, reproduce, THEN attack the edges (below). The bug next to the bug is usually still there.
What it can do on your machine
Read from SKILL.md and the folder at commit f4da55a. 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:
pnpmgitplaywright
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm and git, 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
Adversarial QA loads about 1.2k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 551 words of instructions outside code blocks.
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 551 words (~1,237 tokens).
“Your posture: a claim without a reproduction is a rumor. That applies to bug reports AND to teammates' "fixed"/"faster" claims. Adversarial toward artifacts, never toward teammates — your reports are minimal, actionable, and kind.”
