Listing content changes

get_listing_content_changes
Read-only

Return factual listing-content changes from agentcentral-retained snapshots. Diffs title, brand, description, product type, status/classification, browse classifications, item/package dimensions, main image, bullets, and image set from append-only Catalog Items history, plus backend generic_keyword from weekly Listings Items snapshots. Returns one row per changed field with source snapshot dates. Amazon exposes no native listing edit-history API; first-snapshot accounts report insufficient retained history instead of claiming no change. Video and A+ module content are not diffed.

Input Schema

NameRequiredDescriptionDefault
skuNoFilter to a seller SKU. Applies to the weekly backend-keyword source.
asinNoFilter to a single ASIN. Exact match.
limitNoMax changed-field rows to return (1-500). Defaults to 100.
fieldsNoOptional changed-field allowlist.
offsetNoPagination offset (0-100000, default 0). Use the returned pagination.next_offset to continue.
end_dateNoOptional retained snapshot range end, YYYY-MM-DD. Pass with start_date.
start_dateNoOptional retained snapshot range start, YYYY-MM-DD. Pass with end_date.
lookback_daysNoWhen explicit dates are omitted, compare snapshots in this trailing window. Defaults to 30 days.
include_raw_rowsNoFor tabular results, false returns compact rows capped at MCP_TEXT_ROW_PREVIEW_LIMIT (default 10), regardless of limit. Complete-page and custom non-tabular responses may ignore this option; see tool-specific notes. Default true; large full-row responses are capped separately. Freshness fields require include_diagnostics=true in either row mode, where supported.
include_diagnosticsNoTrue enables expanded freshness diagnostics. Where supported, snapshot_capture_at and snapshot_data_through_date are populated only when include_diagnostics=true, in both compact and full-row modes; values may still be null if source data is unavailable. Default false. Basic empty-result data-window diagnostics are included by default when available.

A4.3/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/openWorld=false/destructive=false, and the description adds substantial context on top: append-only Catalog Items history plus weekly Listings Items snapshots, one row per changed field with source snapshot dates, and the important behavioral guarantee that accounts with only a first snapshot report 'insufficient retained history' rather than falsely claiming no change. That negative-result caveat is exactly the kind of behavior an agent cannot infer from annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core scope is front-loaded in the first sentence, and the caveats (no native API, first-snapshot behavior, video/A+ exclusion) are placed after it. The middle sentence is long because it packs a full field list into one clause, which is slightly heavier than necessary given the enum already lists them.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 10-parameter read tool with full schema coverage, annotations, and an output schema, the description covers the essentials: sources, row granularity, snake_case caveats, and exclusions. It leaves the interplay between start_date/end_date and lookback_days to the schema, which is acceptable but slightly thins out an otherwise complete definition.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and every parameter already has a description, so the baseline is 3. The description does not add syntax or constraint detail for sku, asin, date range, lookback_days, or the fields allowlist beyond what is already in the schema — it only names the diffable fields generically, which the enum already enumerates precisely.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource ('Return factual listing-content changes') and then enumerates exactly which fields are diffed (title, brand, description, dimensions, images, bullets, generic_keyword). It also names its data sources, making it clearly distinguishable from sibling history tools like get_ads_change_history or get_action_history, which cover ad/action domains rather than listing content.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage context is clear: it is for detecting what changed in a listing across a snapshot window, and the description notes that Amazon exposes no native edit-history API, which explains why an agent must route here. It also states exclusions (video and A+ modules are not diffed) and the first-snapshot edge case. It stops short of explicitly naming an alternative tool to use for those excluded content types.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
