— HOW IT BEHAVES
How Document comparison produces its result
The mechanics behind this specific template — what it reads, what it calculates, and where a human stays in the loop.
Difference, not description
Two states are compared directly, so what actually changed is separated from what only reads differently.
Criteria-based analysis
Material is assessed against explicit criteria you control, so the same standard is applied on every run.
Grounded in your own material
The run works from documents and data you supply, so conclusions are anchored to your evidence rather than to general model knowledge.
Why this is expensive by hand
Version comparison by eye misses the changes that matter and flags the ones that don't. Contract and policy versions is the typical trigger — see what actually changed between two drafts before signing or approving. Done properly it is defensible; done at pace it becomes a judgement call nobody can retrace. And "properly" usually means 1 day of manual work.
How this Skill produces it
Skillsize turns that work into a Skill: you supply the material, and what comes back is a list of meaningful differences with context, with substantive changes separated from noise. The criteria, ordering and review points that make the answer trustworthy are encoded in the Skill itself — which is the difference between a structured method and a prompt someone pastes in. Net effect: 1 day down to ~10 minutes, no drift between runs, and every conclusion traceable back to the evidence behind it.
Who it's for
- Independent consultants codifying their own methodology
- Strategy and transformation teams standardising delivery
- Internal advisory functions under pressure to produce faster
- Operators who need defensible output, not a one-off chat answer
Run it in Skillsize — or export it anywhere
Document comparison exports as a structured SKILL.md file and is MCP-ready, so the same method runs in ChatGPT, Claude, Copilot or your own AI products. Adapt it to your methodology, and the intelligence stays yours — not locked to one vendor.
