Readme First Run Check

Checks Agent Skills (SKILL.md folders) for portability and common mistakes with a standard-library Python script, then explains each finding and the fix.

Reads a job post for a job seeker and says in plain words what the job is, which requirements are firm and which are wishes, what the post leaves out (pay, location, hours, team), which phrases are worth a question, and what to ask the recruiter. It quotes the post for everything and never guesses about the employer.
