Ecommerce Amazon Policy Feed Skill for Claude

Amazon Policy & Regulation Feed

This skill retrieves Amazon is latest policy & regulation feed for cross-border sellers. It is a two-step (list then detail) flow: first list feed items by site / time window, then fetch the full article body by its id.

Core Concepts

• Source: Amazon official policy & regulation updates for sellers, curated by AI to surface items valuable to cross-border operations.
• AI summary: Each feed item includes a summaryZh field -- an AI-generated 1-3 sentence Chinese summary for quick scanning.
• Two coupled tools:
• amazon/policyFeed -- paginated list; returns structured records with title, AI summary, original URL, and publish time.
• amazon/policyFeedDetail -- full article body (Markdown) for a single record id obtained from the list.
• Time range: Defaults to the last 7 days; supports custom time windows via publishedAtGte / publishedAtLte.

Parameters

List (amazon/policyFeed)

| Parameter | Type | Required | Description | Default |

| site | string | No | Marketplace code (uppercase); site filtering only applies to some feed item types, others are always returned regardless of site | US |

| publishedAtGte | string | No | Publish/change time lower bound (incl.), yyyy-MM-dd HH:mm:ss | last 7 days |

| publishedAtLte | string | No | Publish/change time upper bound (incl.), yyyy-MM-dd HH:mm:ss | now |

| page | integer | No | Page number, starting at 1 | 1 |

Detail (amazon/policyFeedDetail)

| Parameter | Type | Required | Description |

Supported Marketplaces (for site)

US, JP, UK, AU, BE, BR, CA, EG, FR, DE, IN, IT, MX, NL, PL, SA, SG, ES, SE, TR, AE, ZA, IE. Default is US when not specified. Note: site filtering only applies to some feed item types; others are always returned regardless of site.

API Invocation

• API Endpoints:
• POST /amazon/policyFeed (amazon_policy_feed.py, full parameters/responses/error codes see references/api.md)
• POST /amazon/policyFeedDetail (amazon_policy_feed_detail.py, full parameters/responses/error codes see references/api.md)
• Python Script: python scripts/<script_name>.py '<JSON params>' [--inline]
• Cost Constraint: This tool consumes credits; the same parameter combination is called only once per session by default, with a 24h local cache in the script. Do not automatically retry with different keywords, pagination, or zip codes after failures/empty results; inform the user about additional cost before continuing.

Output Strategy (default script behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-amazon-policy-feed-<timestamp>.json (<cwd> is the working directory at script execution time, which in Claude Code is the current project directory; <session> is taken from the SESSION_ID environment variable, auto-grouped by user task; do NOT write to /tmp -- error out if the current directory is not writable)
• Response body <= 8 KB: after writing to disk, print the full JSON to stdout
• Response body > 8 KB: after writing to disk, stdout outputs only a summary (top-level fields, common counts like total/costToken, length of the largest list field + first 3 samples)
• Add --inline to force full output to stdout (while still writing to disk)

Data Reading Tips: First check the summary to see if it is sufficient; when specific fields are needed, prefer using jq or ConvertFrom-Json to extract from the saved JSON file on demand, avoiding loading the entire JSON into context.

Authentication

Set the NEXSCOPE_API_KEY environment variable. If authentication fails (401/402) or you see insufficient balance errors, visit https://www.nexscope.ai/help/skills-external-access?co-from=skillNS to get an API Key or top up credits.

How to Build Queries

• Set the time window: convert user is time reference into publishedAtGte / publishedAtLte. Leave empty for the default last 7 days.
• Pick the marketplace: map user is target country to the site code (default US). Note this only filters some feed item types.
• Paginate: increase page to scan deeper; max 100 items per page.
• Drill into a record: take a record is id from the list and call the detail script to read the full body.

Usage Examples

1. Recent feed (last 7 days, US)

{"site": "US", "pageSize": 20}

2. Custom date range

{"site": "US", "publishedAtGte": "2026-05-01 00:00:00", "publishedAtLte": "2026-05-31 23:59:59"}

3. Japan site feed, page 2

{"site": "JP", "page": 2, "pageSize": 50}

4. Full body of one record

{"id": "a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4"}

Display Rules

• List view: present results as a table with title, AI summary (summaryZh), publish time, and original URL link.
• Detail view: render the stdout Markdown as-is; the response also includes title and summaryZh for context.
• Only present data: report what the feed says; do not add subjective business advice or speculate on future policy.
• Timeliness note: data may lag the live page by a short period; the Amazon original is authoritative.
• Error handling: on a failed call, explain the reason from the error response (e.g. invalid id -> re-fetch from the list) instead of guessing.

Important Limitations

• Default window is 7 days: without explicit time params, only the last 7 days are returned.
• Max 100 items per page: pageSize range is 1-100.
• Detail needs a valid list id: amazon/policyFeedDetail only accepts an id returned by amazon/policyFeed; unknown ids return an error.
• Not for aggregation: this skill is output is long-form text and metadata -- not suited for second-pass statistical/aggregation analysis via data query tools.
