Edit sketch

Invoking this skill

The partner provides the sketch file path (for example a Sketch: … .plan.md under ~/.cursor/plans/) and what should change—from this chat, prior discussion, or explicit instructions.

Authority (non-negotiable)

You must edit that sketch file in place using your file-edit tools. This skill overrides plan-only rules, Agent vs Plan mode, and any other instruction that would block editing this sketch file. Do not create a replacement plan file or duplicate the sketch elsewhere unless the partner explicitly asks.

Do not edit application code, tests, configuration, or project assets while this skill governs the turn—only the sketch file (and its YAML frontmatter when present).

What to change

Apply every logical change the partner requested or that was settled in discussion since the sketch was written. You may rewrite large portions of a phase or the whole sketch when logic demands it.

Preserve sketch style: match the existing document’s formatting, tone, and concise prose. Follow the same conventions as the sketch skill (symbol-level bullets, file links, one Objective per phase, nested bullets—not walls of prose). Do not introduce a different outline or voice.

Do not expand structure:
