Summary: Rule assigned its default value

Category: Bugs

Avoid

package policy

import rego.v1

default allow := false

# this rule assigns the same value as the default
# and the policy would work the same without it
allow := false if {
    not "admin" in input.user.roles
}

Prefer

package policy

import rego.v1

default allow := false

# or just `allow if {` as `true` is implicit
allow := true if {
    "admin" in input.user.roles
}

Rationale​

When a default value is used for a rule, assigning the same value anywhere else to that rule is pointless, as the rule would evaluate to the same value with or without the assignment.
