# Feature Research

**Domain:** Public-first gear discovery platform with catalog enrichment
**Researched:** 2026-04-09
**Confidence:** MEDIUM-HIGH
**Milestone scope:** v2.1 Public Discovery — builds on v2.0 multi-user foundation

---

## Context: What Already Exists (v2.0)

These are shipped. New features below only mention them when v2.1 extends them:

- Full gear collection CRUD with weight/price tracking, categories, images
- Planning threads with candidate comparison, ranking, pros/cons, impact preview
- Named setups with classification, donut chart, weight breakdowns
- PostgreSQL multi-user data model, Logto OIDC external auth
- S3 image storage (MinIO), global item catalog with tags and search
- User profiles with avatar/bio, public setup sharing
- Catalog-driven add flow, global FAB, item/catalog detail pages
- MCP server (19 tools), API key + OAuth auth methods

All features below are **new for v2.1** unless explicitly marked "extend existing."

## Feature Landscape

### Table Stakes (Users Expect These)

Features that public-first gear discovery platforms are expected to provide. Missing these makes the product feel broken or hostile to new visitors.

| Feature | Why Expected | Complexity | Notes |
|---------|--------------|------------|-------|
| Browse catalog and setups without login | All comparable platforms (Lighterpack shared lists, BikeGearDatabase, RTINGS) allow full read access. Forcing login before browse kills SEO and casual discovery. | LOW | Middleware change: lift auth guard from all GET /api/* endpoints. Public setup sharing already exists at v2.0 — generalize to all read routes. Session-optional pattern already proven. |
| Discovery landing page with catalog search prominent | RTINGS, Wirecutter, and BikeGearDatabase all lead with search or category browse above the fold. Users arriving from search engines expect to search immediately, not to log in. | MEDIUM | Replace dashboard for unauthenticated visitors. Search bar + tag chips already exist as FAB overlay — promote to inline page hero. Authenticated users still see their dashboard. Route-level auth split. |
| Contextual auth prompt only on write actions | Users must understand the access model without reading documentation. "Browse freely, sign in to save" must be self-evident. Confusing this causes drop-off. | LOW | Inline "Sign in to add to your collection" CTA on catalog item detail pages. No login wall on any browse action. |
| Product attribution: brand and manufacturer fields | Any gear database users trust shows where a product originates. Missing attribution makes catalog look scraped or unverifiable. | LOW | Add `brand`, `manufacturer` fields to catalog items schema. Already has `name` — add structured attribution alongside. Display prominently on detail pages and cards. |
| Image source attribution display | Legal requirement and trust signal. Gear Patrol, BikeGearDatabase, and manufacturer catalogs all credit image source. Omitting creates IP risk on manufacturer-supplied images. | LOW | Add `imageCredit` (display text, e.g. "Apidura") and `imageSourceUrl` fields to catalog items. Display as "Photo: [credit]" beneath product images on detail pages. |
| Community usage signal on catalog items | Users expect to see "owned by N people" or "in N setups" to gauge real-world adoption. Lighterpack shows this per shared list. RTINGS shows review counts. | LOW | `ownerCount` already exists on catalog items in v2.0. Surface it prominently on catalog cards and detail pages. Add "appears in N setups" count derived from setupItems. |
| Shareable catalog item and setup URLs resolve without login | Public-first means deep-linking works. If a setup or catalog item URL is shared, it must render for anyone — no login redirect. | LOW | Detail pages already exist at v2.0. Verify: unauthenticated API responses work end-to-end, meta tags render, no auth redirect on page load. Likely already 90% working given public setup sharing. |

### Differentiators (Competitive Advantage)

Features that set GearBox apart from Lighterpack (lists only, no catalog), BikeGearDatabase (editorial, not user collections), and generic wishlist tools.

| Feature | Value Proposition | Complexity | Notes |
|---------|-------------------|------------|-------|
| Discovery landing feed (community setups + catalog items) | No direct competitor combines a global gear catalog with user setup feeds. Lighterpack has no discovery page. BikeGearDatabase is editorial, not community-driven. GearBox can show real user gear choices with weight data. | MEDIUM | Two feed sections: (a) recently shared public setups sorted by recency, filterable by category; (b) popular/new catalog items by ownerCount. No algorithm needed at launch — recency + ownerCount is sufficient and honest. |
| Agent-powered catalog seeding via MCP tools | Unique to GearBox. No other gear platform has agent-friendly structured import. Enables rapid catalog population by Claude agent swarms without manual data entry. Programmatic SEO value compounds with catalog size. | HIGH | Requires: bulk create MCP tool, structured import with dry-run/preview mode, attribution tracking on agent-inserted records. GearBox already has MCP server and API key auth — foundation exists. |
| Catalog enrichment infrastructure with provenance tracking | Enables crowd + agent contributions with full source tracking. Comparable to Wikipedia's citation model but structured. Builds long-term trust in catalog data quality. | MEDIUM | New schema fields: `sourceUrl`, `sourceType` (enum: manufacturer / community / agent / import), `contributedBy` (userId or agent identifier string), `verifiedAt`. Migration only, lightweight UI needed initially. |
| SEO-indexable catalog pages ranking for product searches | Public catalog pages that rank for "[product name] weight specs" are a major organic acquisition channel. RTINGS built a durable traffic moat this way via programmatic SEO. GearBox can do the same for gear. | MEDIUM | Pages already exist. Add: `<title>` tags with product name + category, OG meta tags, JSON-LD Product schema markup. Primary complexity: TanStack Router is client-rendered — crawlers need either SSR or static prerender for bots. This is the phase's primary technical risk. |
| Setup impact preview teaser on public catalog pages | Showing "add this to your setup and base weight changes by +Xg" is unique. No other gear catalog does this. Showing the feature on public pages teases value and drives sign-up intent. | MEDIUM | Extend existing impact preview (v1.3) to show a teaser CTA on unauthenticated catalog detail pages: "See how this affects your setup → [Sign in to try]". Requires no new backend work — frontend auth-conditional render. |

### Anti-Features (Commonly Requested, Often Problematic)

| Feature | Why Requested | Why Problematic | Alternative |
|---------|---------------|-----------------|-------------|
| Algorithmic feed ranking using engagement signals | "Show popular content" feels natural | Requires engagement data volume that does not exist at v2.1 scale. Empty or manipulated feed is worse than no feed. Gaming and spam risk immediately. | Simple recency + ownerCount sort. Add engagement signals only when data volume and moderation infrastructure justify it. |
| Open wiki-style catalog editing (anyone edits any item) | Fastest path to catalog enrichment | Data quality collapses without moderation. Adversarial edits, edit wars. Requires revert/history infrastructure. Already decided out-of-scope in PROJECT.md. | Structured contributions: users submit items, agents bulk-seed with attribution, admins verify. provenance fields track every change. |
| Bulk catalog import from scraped external sources | "Just import all BikeGearDB items" | Copyright risk. Data quality issues. Stale data. Attribution impossible — you do not know who owns the content. Legal exposure. | Agent-seeding via MCP with explicit source tracking. Manual + agent creates clean provenance chain with `sourceUrl` per item. |
| Real-time "X users viewing this" presence indicators | Social proof, FOMO feeling | Zero signal value at current traffic scale, adds WebSocket complexity, privacy concern for a utility tool. | ownerCount ("X people own this") is sufficient social proof without live presence tracking. |
| Comments on catalog items or setups | Community enrichment, Q&A | Freeform UGC explicitly blocked in PROJECT.md until moderation infrastructure exists. Moderation requires policy, tooling, reporting. | Structured fields only: tags, ratings, attribution. Defer freeform to future milestone after moderation is designed. |
| Social follow / activity feed | "See what friends added" | Social graph is a separate product. Deferred explicitly in PROJECT.md. Notification infrastructure, feed ranking, retention loops all out of scope. | Public setup browsing by category or recency is sufficient discovery without requiring a follow graph. |
| Infinite scroll personalized feed | "Netflix for gear" | Personalization requires user history. Unauthenticated visitors have no history. Personalized recommendations require ML infrastructure far beyond v2.1 scope. | Category-filtered browse + search. Personalization post-login once collection data exists is a v3+ feature. |

### Dependency Notes

- **Public browse is the prerequisite for everything.** Auth middleware change must land first. All other v2.1 features depend on unauthenticated API access working correctly.
- **Catalog enrichment schema must precede agent MCP tools.** The bulk create and import MCP tools write attribution fields. Building tools before schema means schema-breaking changes later.
- **SEO crawlability is the primary technical risk.** TanStack Router renders client-side. Search engine bots do not execute JavaScript. Without SSR or a static prerender pass, catalog pages will not be indexed. This is a known gap with the current stack — needs a solution before SEO-targeted work makes sense. Defer SEO metadata work to P2 until crawlability is resolved.
- **Agent seeding is high complexity but high leverage.** It is both a catalog population tool and a v2.1 launch enabler. Without sufficient catalog items, the discovery feed is thin and the platform feels empty. Prioritize MCP tooling early so catalog seeding can run in parallel with UI work.

## MVP Definition

This is a subsequent milestone on an existing shipped product. MVP here means minimum to deliver the v2.1 goal: public-first discovery platform.

### Launch With (v2.1 core)

- [ ] Public browse without login — lift auth guard from all GET routes. Every other feature depends on this.
- [ ] Discovery landing page — replaces dashboard for unauthenticated visitors. Catalog search hero + two feed sections (recent setups, popular catalog items). Recency + ownerCount sort, no algorithm.
- [ ] Catalog enrichment schema migration — add `brand`, `manufacturer`, `sourceUrl`, `sourceType`, `imageCredit`, `imageSourceUrl`, `contributedBy` fields. Schema first, UI follows.
- [ ] Image attribution display on catalog detail pages — "Photo: [credit]" below product images, sourced from new `imageCredit` field.
- [ ] Agent MCP catalog seeding tools — bulk create endpoint/tool, structured import with attribution, dry-run/preview mode, batch result reporting.
- [ ] Initial catalog population via agent — run agent seeding for 3-5 priority categories (bikepacking bags, tents, sleeping bags, navigation devices, cycling computers). Target: 100+ catalog items with attribution.
- [ ] Community usage signals surfaced — ownerCount and "appears in N setups" count prominent on catalog cards and detail pages.

### Add After Core is Stable (v2.1.x)

- [ ] Contextual "See how this affects your setup" CTA on public catalog pages — setup impact preview teaser with login prompt. Add once public browse is confirmed stable.
- [ ] Manufacturer/brand filter on catalog browse — add brand as a filterable facet. Only valuable once catalog volume justifies filtering (target: after initial seeding).
- [ ] SEO metadata on catalog pages — `<title>`, OG tags, JSON-LD Product schema. Add after crawlability solution is determined.

### Future Consideration (v2.2+)

- [ ] Personalized discovery feed post-login — requires collection data volume and recommendation design.
- [ ] Verified catalog item badge — admin-marked verified items. Requires admin tooling.
- [ ] User-submitted catalog enrichment — structured form to suggest corrections or add missing items. Requires contribution review workflow.
- [ ] Engagement signals in feed — view count, saves. Requires data volume to be meaningful.
