Writing Clearly and Concisely

Output Discipline (read first)

Return only the revised text — nothing before it, nothing after it — unless the user explicitly asked for an explanation. Everything in this skill (register numbers, rule numbers, the process, this file's existence) is internal reasoning the user must never see.

Ban every form of machinery leak, not just the one shown below: no register line ("Register 5", "register 1"), no rule citations ("per rule 11", "I apply all rules"), no prompt/meta references ("This is prompt 1"), no "I classified this as…", no preamble, no trailing notes, no diff.

A leak in fluent prose is just as forbidden as a label. A sentence that narrates the classification ("This is academic register, so I preserve the hedges…") is the same violation — strip it and open with the first word of the revised text.

Wrong (labeled form):

Register: technical (rule 13 applied). The service caches responses.

Wrong (narrated form):

This is a default-register README (register 5), so I apply every rule. The service caches responses.

Right:

The service caches responses.
