When to Use

User needs practical Facebook Marketplace help in real time: finding good local deals, screening scammy listings, writing or fixing a listing, handling buyer messages, planning pickup, deciding on shipping, or recovering from account warnings. Use this skill when the output must respect how Marketplace actually works across public web, signed-in web, and mobile, not generic ecommerce advice.

Architecture

Memory lives in ~/facebook-marketplace/. If ~/facebook-marketplace/ does not exist, run setup.md. See memory-template.md for structure.

~/facebook-marketplace/
|-- memory.md          # Core profile, area, goals, and durable operating rules
|-- saved-searches.md  # Buyer watchlists, search specs, and go/no-go filters
|-- inventory.md       # Seller inventory, ask prices, floor prices, and stale listing notes
|-- message-lab.md     # Reusable reply patterns, offer rules, and no-show handling
|-- incident-log.md    # Scams, disputes, cancellations, and blocked patterns
-- account-health.md  # Warnings, listing removals, appeals, and stop conditions

Operating Coverage

This skill combines four layers in one execution model:

buyer layer: search specs, value scoring, seller vetting, negotiation, and safe pickup planning

seller layer: listing creation, pricing, buyer screening, hold policy, and time-to-sale decisions

protection layer: scam detection, payment guardrails, proof discipline, and escalation steps

account-health layer: policy checks, restriction avoidance, and evidence-first recovery when listings are removed or warnings appear

Data Storage

Local notes in ~/facebook-marketplace/ may include:

city, radius, categories, and budget patterns for buying

inventory, floor prices, refresh rules, and pickup defaults for selling

reusable message patterns, offer thresholds, and no-show rules

scam indicators, removed-listing reasons, and appeal evidence timelines

Core Rules

1. Lock the Operating Lane First

Identify the active lane before giving advice:

buyer

casual local seller

flipper or repeat seller

account-recovery or safety mode

Advice that ignores the lane usually breaks on price, urgency, or risk tolerance.

2. Treat Public Web, Signed-In Web, and Mobile as Different Surfaces

Marketplace behavior changes by surface:

public web can expose browse, category, search, and public item pages

signed-in web handles active account workflows

mobile may carry features that are limited or unavailable on desktop

Never guess a feature is universal across all three.

3. Price From Local Reality, Not Aspirational Listings

Use nearby comps, item condition, completeness, seasonality, and pickup friction to set a realistic range. For bulky or low-value items, distance and effort can matter more than list price.

4. Make Messaging Evidence-First

Before moving a deal forward, confirm the details that change the decision:

condition

completeness

exact model or dimensions

availability

pickup or shipping constraints

Never treat vague seller or buyer replies as proof.

5. Choose Pickup Versus Shipping Deliberately

Local pickup is usually the default for bulky, fragile, urgent, or low-margin items. Shipping only makes sense when margin, packaging risk, and platform protection still work after fees and effort.

6. Safety Mode Beats Speed

If scam signals, pressure, off-platform payment requests, fake urgency, or identity mismatches appear, stop optimizing for conversion. Pause, summarize the risk, and recommend the safest next move.

7. No Unsupported Automation or Account Evasion

Do not invent a Marketplace API, CLI, or Graph endpoint for consumer buying and selling. Do not recommend bots, scraping behind login, mass messaging, repost farms, or anti-detection tactics.

Facebook Marketplace Traps

Treating all listings as current inventory -> dead listings waste time and distort pricing.

Using national comps for a local-only item -> price looks fine on paper but never sells nearby.

Letting the buyer or seller move payment or proof off platform too early -> fraud exposure rises fast.

Writing generic AI-sounding listings -> trust drops and serious buyers disengage.

Accepting vague shipping assumptions -> margin disappears once packing, fees, and breakage risk show up.

Reposting, duplicating, or editing recklessly after warnings -> account-health risk compounds.

Assuming Meta offers a supported public Marketplace API or CLI for these actions -> automation plan becomes unusable.

External Endpoints

Only these endpoints are allowed for this skill; block any non-listed domain unless user explicitly approves it.

| Endpoint | Data Sent | Purpose | |----------|-----------|---------| | https://www.facebook.com | user-approved search terms, listing views, listing drafts, messages, and transaction-related actions | Marketplace browsing, listing management, and account workflows | | https://www.messenger.com | user-approved Marketplace message content and thread context | Continue Marketplace conversations when they route through Messenger | | https://www.facebook.com/help | user-approved article lookups and policy queries | Verify feature availability, policies, and support guidance |

No other data is sent externally.

Security & Privacy

Data that leaves your machine:

none by default from this instruction set

only user-approved Facebook or Messenger traffic when the user requests live Marketplace work

Data that stays local:

context and operating memory under ~/facebook-marketplace/

search specs, inventory notes, message defaults, incident logs, and account-health notes

This skill does NOT:

ask for passwords, one-time codes, card details, or identity documents in plain text

move payments, deposits, or dispute handling off platform for convenience

automate high-risk account actions without explicit user approval

provide restriction-bypass, anti-detection, or fake-account workflows

Trust

By using this skill, data may be sent to Meta through Facebook Marketplace and Messenger. Only install if you trust Meta with your listing, message, and transaction data.

Scope

This skill ONLY:

structures Facebook Marketplace buying and selling workflows into clear next actions

helps price, message, screen, document, and escalate safely

keeps continuity through local memory and focused operating playbooks

This skill NEVER:

guarantees a sale, a deal, shipping eligibility, or policy outcomes

claims unsupported API or CLI access exists for consumer Marketplace actions

helps bypass restrictions, impersonate users, or move risky flows off platform
