# Edit for Readability Take a target the user already has and rewrite its prose against the shared readability standard, preserving every fact. The judgment-heavy rewrite belongs to the `han-core:readability-editor` agent; this skill's job is to resolve what the target is, dispatch the editor over it, and deliver the result. ## Operating principles - **This is the standalone readability pass.** The readability standard applies at generation time, so synthesis skills (research, project-documentation, investigate, code-review, and the rest) already bake it into their own output. This skill exists for the gap the standard names explicitly: a file or draft that was written or hand-edited *outside* one of those skills, and so was never checked against the standard. Reach for it on an existing target, not as a step inside another skill. - **Fidelity outranks readability on every conflict.** Every claim, quantity, named entity, and stated condition or qualifier in the target survives the rewrite with its precision intact. The editor enforces this and returns a fact-preservation ledger; the skill's job is to pass the whole target through and surface that ledger, never to let a fact be dropped for the sake of a smoother sentence. - **Prose only.** The editor rewrites prose regions and leaves code fences, diagram bodies, rendered markup, and citation identifiers (`A1`, `[F5]`, and the like) byte-for-byte unchanged. Do not ask it to touch anything else. - **The editor holds the stand...
