ARGUS reads your code. WHETSTONE breaks it. YUMA proves it ships.
Your code works. But does it work well? ARGUS scores your code across 6 structural dimensions. YUMA evaluates your test coverage and finds the gaps. WHETSTONE generates targeted mutations that should break your tests. Then it tells you which ones survive.
Not a linter. Not a formatter. An architectural quality engine that finds the problems your toolchain was never designed to look for.
This is what your vibe-coded endpoint looks like to ARGUS.
app.post('/api/users', async (req, res) => {
const user = req.body
const result = await db.query(
`INSERT INTO users VALUES
('${user.name}', '${user.email}')`
)
const token = jwt.sign(user, 'secret123')
res.json({ user: result, token })
})router.post('/api/users',
rateLimit({ max: 10, window: '1m' }),
validate(createUserSchema),
async (req, res, next) => {
try {
const user = await userService.create(
req.validated
)
const token = await authService
.issueToken(user.id)
res.status(201).json({
id: user.id, email: user.email
})
} catch (err) { next(err) }
}
)The first version works. It passes basic tests. An AI would generate it. A junior developer would ship it. ARGUS catches every issue a senior engineer would flag in code review: SQL injection, hardcoded secrets, no input validation, no error handling, exposed internal data. Then it tells you exactly what to fix.
Not a score. A map of where your code is weak.
A single quality number is useless. 72/100 tells you nothing actionable. ARGUS breaks quality into 6 independent dimensions so you know exactly where to invest your time. The weakest dimension is where the return on improvement is steepest.
Your tests look green. Are they actually catching anything?
100% line coverage means nothing if your tests don't catch behavioral changes. WHETSTONE generates targeted mutations. Each one designed to change behavior in a way your tests should catch. The ones that survive are your real gaps. The ones that tell you exactly which tests to write next.
if (user.isAdmin)→if (!user.isAdmin)limit > 0→limit >= 0if (!token) throw→// guard removedmerge(source, target)→merge(target, source)2 of 4 mutations survived. That means half of the behavioral changes a bug or an attacker could introduce would go undetected. WHETSTONE tells you exactly which tests to write next.
4 more tools. Same $5/mo.
ARGUS, YUMA, and WHETSTONE are the headliners. These four handle the rest of what a thorough code review should cover. Each one catches a category of problems that the others can't.
