Unicorn Platform

WORKING SLICE
Assemble a startup landing page from a small constrained component library, edit claims and imagery and publish a static export. Include pricing or testimonials only when the owner supplies real approved content.

Build this scoped Unicorn Platform-inspired workflow with a documented data model and visible failure states.

Architecture
- Eleventy, Markdown content and typed JSON section manifests for a static website.
- A local Node editor/build command with Sharp image processing; generated files publish to a user-owned host.

Prerequisites and limits
Node, a selected output folder, licensed content/assets and a user-owned deployment target. DNS, email delivery and any server-side forms require separate configuration.
Outside this release: template polish, hosted publishing, forms, and AI copy convenience; large template marketplace

Data model and correctness
landing-page sections, approved copy, theme tokens, CTA destinations and static publish revisions
Invariant: Empty content fields remain absent rather than becoming fabricated social proof; every CTA must have an intentional reachable destination.
Build into a new output directory from a saved content revision. Preview at narrow and wide widths and deploy the complete artifact atomically; retain the previous release.

Security and privacy
Escape content, sanitize Markdown, constrain asset paths and never embed API secrets in the static output. Private content requires a real authenticated server rather than a hidden URL.

Recovery and export
Export source Markdown/JSON and original assets alongside the generated site. A clean build from that archive must not depend on an editor database.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Assemble a startup landing page from a small constrained component library, edit claims and imagery and publish a static export. Include pricing or testimonials only when the owner supplies real approved content. Record prerequisites, select representative user-owned fixtures and document the unsupported features: template polish, hosted publishing, forms, and AI copy convenience; large template marketplace
2. Phase 2 — Durable model. Model landing-page sections, approved copy, theme tokens, CTA destinations and static publish revisions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Empty content fields remain absent rather than becoming fabricated social proof; every CTA must have an intentional reachable destination.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Build into a new output directory from a saved content revision. Preview at narrow and wide widths and deploy the complete artifact atomically; retain the previous release.
4. Phase 4 — Permissions and integration failure. Escape content, sanitize Markdown, constrain asset paths and never embed API secrets in the static output. Private content requires a real authenticated server rather than a hidden URL. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export source Markdown/JSON and original assets alongside the generated site. A clean build from that archive must not depend on an editor database. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Export a page with no testimonials and show no placeholder endorsements; navigation and CTA focus order remain usable on a narrow viewport. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Export a page with no testimonials and show no placeholder endorsements; navigation and CTA focus order remain usable on a narrow viewport.
Use real source data or clearly labeled fixtures. Explain unsupported input and provider failures; do not fabricate analytics, delivery receipts, accuracy claims or security guarantees.

# AGENTS.md — Build guide for Unicorn Platform

## Project scope
Assemble a startup landing page from a small constrained component library, edit claims and imagery and publish a static export. Include pricing or testimonials only when the owner supplies real approved content.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Unicorn Platform, assemble a startup landing page from constrained components and export static code. The hard boundary is template polish, hosted publishing, forms, and ai copy convenience, plus editor polish, hosting, templates, and ecosystem.
Use the implementation prompt below to define the deliverable. Complete each phase's acceptance checks before extending the scope.

## Working agreement
- Inspect the repository and its existing instructions before choosing paths, dependencies or commands. Keep one coherent stack and explain changes to the proposed architecture.
- Plan a vertical slice that accepts a real input and produces the useful output described below. Persist only the state the prompt calls for; respect memory-only and upstream-managed workflows. Use fixtures only when they are clearly labelled.
- After scaffolding, document the actual install, development, check and build commands in README and keep them synchronized with the package or project manifest. Do not report commands as successful unless they ran.
- Work in small steps. At handoff, list implemented flows, checks actually performed, remaining blockers, and any credentials or provider setup the owner must supply.
- Do not publish, spend money, contact customers, delete source data or run irreversible migrations without the project owner's authorization.

## Prerequisites
- Node, a selected output folder, licensed content/assets and a user-owned deployment target. DNS, email delivery and any server-side forms require separate configuration.
- Implementation components: Eleventy, Markdown content and typed JSON section manifests for a static website. A local Node editor/build command with Sharp image processing; generated files publish to a user-owned host.
- Scope boundary: template polish, hosted publishing, forms, and AI copy convenience; large template marketplace

## Stack and architecture
- Eleventy, Markdown content and typed JSON section manifests for a static website.
- A local Node editor/build command with Sharp image processing; generated files publish to a user-owned host.
- Domain model: landing-page sections, approved copy, theme tokens, CTA destinations and static publish revisions

## Security and data integrity
- Escape content, sanitize Markdown, constrain asset paths and never embed API secrets in the static output. Private content requires a real authenticated server rather than a hidden URL.
- Correctness boundary: Empty content fields remain absent rather than becoming fabricated social proof; every CTA must have an intentional reachable destination.
- Build into a new output directory from a saved content revision. Preview at narrow and wide widths and deploy the complete artifact atomically; retain the previous release.
- Export source Markdown/JSON and original assets alongside the generated site. A clean build from that archive must not depend on an editor database.

Read the linked SKILL.md and its dependencies before adding a skill. Select only the skills matching this project's runtime and task; their documentation does not supply API access, credentials or approval to perform external actions. Pin the reviewed revision where the tool supports it. Follow the chosen agent's documented project-level installation mechanism.

## Distribution ideas
These are optional planning notes. Obtain the owner's approval before publishing or contacting anyone.
- Demonstrate the actual Unicorn Platform-inspired workflow with owned or clearly labeled sample data: Assemble a startup landing page from a small constrained component library, edit claims and imagery and publish a static export. Include pricing or testimonials only when the owner supplies real approved content.
- Publish a reproducible walkthrough with this observable result: Export a page with no testimonials and show no placeholder endorsements; navigation and CTA focus order remain usable on a narrow viewport.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: template polish, hosted publishing, forms, and AI copy convenience; large template marketplace Avoid guaranteed savings, performance scores or implied endorsement.

Preserve this rule: Empty content fields remain absent rather than becoming fabricated social proof; every CTA must have an intentional reachable destination.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Build into a new output directory from a saved content revision. Preview at narrow and wide widths and deploy the complete artifact atomically; retain the previous release.

## Completion evidence
Demonstrate the prompt's acceptance scenarios against the scoped workflow. Include setup from a clean checkout and failure recovery. Check persistence across restart and export/restore only for the state the prompt says to store; for memory-only tools, confirm that temporary content is discarded as specified. Record actual results and remaining limitations. A detailed plan alone does not establish a working replacement.
