One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
Owner verbally instructed superintendent on Monday morning to install an additional access hatch in room 204. Materials cost $650, labor was 8 hours at $80/hr. Allowed markup is 12% per Clause 5.3. Create the Change Order Request.

The instructions your model reads when the skill loads.
A change order that just says "extra work — $48,500" gets cut in half in review. A defensible one answers three questions before they're asked: why am I entitled (which contract clause, triggered by what event), what exactly changed (scope delta from the contract baseline), and what does it really cost (built-up pricing plus time). This skill drafts change orders that survive an owner's rep audit — and preserves rights on the impacts you can't price yet.
Ask for what's missing; from a thin brief, draft anyway and mark every gap [confirm]:
Entitlement first. Classify the trigger — it drives the clause you cite:
| Trigger | Typical basis |
|---|---|
| Owner/architect directive or design revision | Changes clause (e.g. AIA A201 §7 / EJCDC / contract equivalent) |
| Differing site condition | DSC clause — Type I (differs from documents) or Type II (unusual for the locality) |
| RFI answer adding work | Changes clause via the RFI/ASI as the directive document |
| Owner-caused delay/interference | Changes + delay provisions (pair with a delay notice) |
Never assert entitlement without naming the clause and the triggering document by number and date. If notice deadlines have passed, say so and frame the submission accordingly — don't hide it.
Pricing build-up. Price from records, not round numbers: labour (crew × hours × loaded rates — base plus burden), material (quantities × quoted prices, attach quotes), equipment (owned at established rates, rented at invoice), subcontractor cost, then apply OH&P at the contract-specified markups on self-performed and sub work separately. Include small-tools/consumables, supervision, and bond/insurance adjustment if the contract allows. Anything estimated rather than quoted gets labelled.
Time. State added work duration and whether it hits the critical path. If time impact can't be fixed yet, request a to-be-determined extension and reserve rights — never write "no schedule impact" as a default.
