+# Clarify spec-stage gate
+
+Opt-in wrap of `/speckit.clarify`. Core already lists the spec taxonomy. This preset adds a stage gate so agents do not dump NFRs, acceptance criteria, edge cases, and similar items into Plan.
+
+Install it if you want that enforcement. Leave it off if core `/speckit.clarify` is enough.
+
+## What it does
+
+It wraps `speckit.clarify` with `{CORE_TEMPLATE}`, so core command updates still land. On top of that it:
+
+- Treats a taxonomy hit as a spec-stage question
+- Defers only implementation method, tech-stack comparison, or task breakdown
+- Pauses when more than 60% of unresolved items would be deferred
+- Adds a MUST-NOT on spec-taxonomy deferral
+
+## Installation
+
+```bash
+specify preset add clarify-spec-gate
+```
+
+## Development
+
+```bash
+specify preset add --dev ./presets/clarify-spec-gate
+specify preset resolve speckit.clarify
+specify preset remove clarify-spec-gate
+```

+
+## Spec-vs-plan stage gate
+
+This preset tightens deferral. Apply it while you scan the spec (the taxonomy lives in the core command below).
+
+For every unchecked checklist item and every Partial/Missing taxonomy category, classify before considering deferral:
+
+1. Match the item against the spec-oriented taxonomy in the core command.
+2. A hit on any taxonomy category is a question candidate for this stage. Do not defer NFRs, acceptance/DoD testability, edge cases, UX empty states, domain constraints, or external-dependency failure modes.
+3. Defer to planning only when the item is specifically about implementation method, tech-stack comparison, or task breakdown.
+4. Mixed items (spec decision plus plan detail): split them and handle the spec part now.
+
+If more than 60% of unresolved items would be marked Defer, pause, report the ratio, and re-check each against the taxonomy before continuing.
+
+Do not use a vague "better deferred to planning" catch-all.
+
+{CORE_TEMPLATE}
+
+## Spec-taxonomy MUST-NOT
+
+MUST NOT defer spec-taxonomy items to Plan. Concurrent-user volume, NFR quantification, acceptance-criteria testability, empty-state UX, and external-dependency failure modes are spec questions. How you implement pagination can wait. Whether the API paginates cannot.
