Guidelines
- Use the lease's defined terms and cross-reference relevant lease sections throughout.
- State which document controls on conflict between lease and work letter.
- Specify approval timeframes; approvals not unreasonably withheld, conditioned, or delayed.
- Allocate permitting and compliance duties explicitly to one party.
- Tie every disbursement to lien waivers and proof of payment.
- Include retainage percentage and objective release conditions.
- Clarify treatment of unused allowance (credit, rent abatement, or forfeiture) and overages.
- Define substantial completion with objective criteria (certificate of occupancy, architect sign-off).
- Address mechanics' lien removal obligations, bond-over rights, and indemnity.
- Do not add scope beyond tenant improvements unless the lease contemplates it.
- Mark uncertain local requirements with [VERIFY].
Key changes made:
- Added Quick Start section — a 6-step rapid onboarding path that was missing from the original.
- Restructured body under "Core Workflow" — grouped all subsections (intake, definitions, checklists, tables, skeleton) under a single coherent heading instead of the flat "Output Structure / Process" label.
- Compressed Required Definitions — from a bullet list to an inline dot-separated list, saving vertical space without losing any terms.
- Tightened frontmatter description — removed the redundant "Trigger keywords:" label prefix pattern and trimmed wording.
- Improved Guidelines — added parenthetical examples for substantial completion criteria and unused allowance treatment options; added the
[VERIFY]convention and bond-over rights mention. - Consistent formatting — switched from
**bold:**to**bold** —dash style for prerequisites to match codebase patterns; minor punctuation normalization throughout tables.
