U Spec Templates
Canonical TEMPLATE.* artifacts for SDD spec writers — domain spec, back spec, front spec, feature spec, flow, component spec, decisions, design-system rules and design-system bundle. Consumed by u-spec-writer, u-spec-back, and u-spec-front, which read templates by path. Resource bundle — no scripts. Not user-invocable.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

u-spec-templates
Resource bundle: canonical templates consumed by SDD spec agents. Templates are read by path (.claude/skills/u-spec-templates/); the directory listing is authoritative.
Index
| Template | Produces | Primary consumer | |---|---|---| | TEMPLATE.spec.md | domains/{domain}/{domain}.spec.md | u-spec-writer | | TEMPLATE.back.md | domains/{domain}/back/{domain}.back.md | u-spec-back | | TEMPLATE.front.md | {SPECS_DIR}/front/front.md (global frontend spec) | u-spec-front | | TEMPLATE.feature.spec.md | {SPECS_DIR}/front/features/*.feature.spec.md | u-spec-front | | TEMPLATE.flow.md | {SPECS_DIR}/front/flow.md | u-spec-front | | TEMPLATE.component.spec.md | design-system/components/*.spec.md | u-fe-spec-writer | | TEMPLATE.decisions.md | {SPECS_DIR}/decisions.md | u-spec-writer | | TEMPLATE.design-system-rules.md | front/design-system-rules.md | u-spec-front | | TEMPLATE.design-system/ | design-system/ bundle (_index.md, tokens.md, composition.md, components.md, implementation.md) | u-spec-front | | FRONTEND-MANDATORY-ARTIFACTS.md | single source of truth for the frontend design-system artifacts the front pipeline must produce and the validator blocks on (F-07) | u-spec-front (produces), u-spec-validator (gates) |
Constraints
- Templates contain `` placeholders — producers MUST resolve every placeholder; none may survive into generated artifacts
- Identifier prefixes used across templates follow the global pattern defined in
u-spec-globals/conventions.md(UC, BR, ST, EV, UI, FL)
