The problem
Sound familiar?
If any of these hit home, this kit was built for your team.
The design file answers the wrong questions
Figma Dev Mode tells engineers what a button looks like. It does not tell them what happens when the API fails, what the empty state looks like, or how animation degrades for reduced motion. Those decisions get made at implementation time: the worst possible moment.
Missing states show up as bugs, not questions
Loading, error, disabled, empty. These are systematically underspecified because designers default to the happy path. Every unchecked state becomes a ticket in the next sprint.
"Ready for Engineering" means something different to everyone
A designer marks a ticket ready. Engineering picks it up and finds an incomplete spec, detached components, and an unanswered question they need before writing a line of code.
Terminology drift creates invisible blockers
Design says "component." Engineering says "component" and means something different. The vocabulary gaps don't surface in meetings. They surface in implementation, when assumptions have already been made.
The sync meeting is a status report in disguise
30 minutes of updates that could have been a Slack message. Nobody leaves with a decision made. The cycle repeats.
What's inside
11 files across 6 deliverable groups
Every deliverable ships in multiple formats. Markdown for Notion, Confluence, Linear, and GitHub. DOCX/XLSX for Microsoft 365 and Google Workspace. PDFs for polished reference guides.
Welcome Guide
Four-page branded PDF covering what the kit is, full artifact inventory, rollout guidance, and adaptation advice by team size.
Handoff Spec Template
Behavioral spec covering Why This Was Built This Way, interaction states, loading/empty/error behavior, accessibility, edge cases, and open questions. Pastes cleanly into Notion, Confluence, Linear, and GitHub PR descriptions.
Handoff Spec Supplemental Guide
Four-page guide for teams without Figma Dev Mode or a design system. Covers exactly what to add to the spec when those tools are absent.
"Ready for Engineering" Checklist
14 items across four categories: Design File, Spec, Accessibility, Engineering Alignment. Three to five minutes per feature. Embed directly in Notion, Confluence, Linear, or GitHub PR templates.
PM + Design Sync Agenda
A decisions meeting, not a status update. Two timed sections, a hard rule that cancels the meeting if neither party has items, and a rolling actions log.
Shared Glossary
25 pre-populated terms across Design, Engineering, Product, and Cross-functional categories. The Common Confusion column names the exact misunderstanding that happens in the wild, not just the correct definition.
AI Integration Guide
Two-page PDF covering Notion AI, Microsoft 365 Copilot, and Linear/Jira via Zapier or Make, with concrete before/during/after patterns and the async meeting pattern. Verified March 2026.

Why this kit
What makes it different
There are a lot of templates out there. Here's why these aren't the same thing.
Covers the behavioral layer Dev Mode was never designed for
Dev Mode handles visual specs. This kit handles what happens when the API fails, what the empty state shows, and why this design decision was made instead of the alternative engineering will suggest at implementation time.
14-item checklist. 3–5 minutes. No bureaucracy.
A 30-item checklist becomes checkbox theater that teams abandon in a quarter. This one was kept deliberately lean. The DOCX version includes a 'Why it matters' column for every item so no one has to take any check on faith.
Markdown-first by design, not as an afterthought
Most spec templates are built in Word, then someone suggests Notion. This kit was designed for Notion, Confluence, Linear, and GitHub PR descriptions from the start. A spec that lives in the same tool as the ticket gets read.
The sync agenda was designed around one principle: decisions, not updates
The template has a hard rule that cancels the meeting if neither party has items the day before. That rule is in the template itself, because the meeting never changes until the template changes.
The Shared Glossary addresses the oldest source of handoff friction
Teams assume they speak the same language because they use the same words. 25 pre-populated terms chosen specifically because they're the ones teams think they agree on until implementation reveals they don't.
This kit is for you if...
- Designers who do handoffs regularly and want a repeatable, defensible process
- Design leads tired of post-handoff bugs and want to eliminate them structurally
- DesignOps practitioners setting up handoff standards for the first time
- Teams that started with the Clarity Kit's handoff checklist and need the full behavioral spec system
Probably not for you if...
- Teams that do not hand off to a separate engineering function
- Organizations already running a mature, documented handoff process
Where to start
Start with your sharpest pain point
Don't try to deploy everything at once. Pick the deliverable that solves your most urgent problem first.
| If your pain is... | Start with | Then add |
|---|---|---|
| "Engineering keeps building the wrong edge cases" | Handoff Spec Template | RFE Checklist (run before every handoff) |
| "We don't have a consistent definition of 'done'" | RFE Checklist | Shared Glossary (define it together) |
| "Our PM–Design sync is a waste of 30 minutes" | PM + Design Sync Agenda | RFE Checklist (agenda input) |
| "Design and engineering don't speak the same language" | Shared Glossary | Handoff Spec Template |
| "Bugs keep coming back from states we didn't spec" | Handoff Spec Template (interaction states section) | RFE Checklist (Spec category) |
