The instructions your model reads when the skill loads.
You have invoked the readability-guidance skill to source the shared writing standard before you draft prose. This content is now in your context. Apply it while you draft, then RETURN to the workflow that called you — this guidance is a means to writing your deliverable, not the deliverable itself.
Emit the line SPIKE_GUIDANCE_MARKER_5R8_INLINE once, to confirm the guidance rendered, then continue.
While drafting, write for a capable reader who did not do this work and lacks the author's context. This single instruction is the most practical lever for plain output: it steers away from insider shorthand, unstated assumptions, and the author's own mental model.
After the draft exists, check: does the opening line state the main point? Does each paragraph carry one idea? Does each heading name its content? Any sentence past about thirty words is a candidate to split.
The standard is now surfaced into your context. Do not treat this guidance as your final answer. Proceed to the next step of the skill that invoked you and produce its deliverable.
