Listing history

listing_history
Read-onlyIdempotent

Timeline of the listing's repository: last events (abandono = no push for 12 months, sumiu, renomeado, readme_mudou, manifesto_mudou), newest first; empty when nothing changed since the series began. The listing page carries the same list as history; updates may be cached for up to 15 minutes. An empty list means no change since the series began — the listing still exists. Stale means no push for 12 months. Reading this endpoint does not refresh the record.

A3.6/5.0
Behavior4/5

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

Annotations already cover readOnly/idempotent/non-destructive, and the description adds genuinely non-obvious behavior: results may be cached up to 15 minutes, and reading the endpoint does not refresh the record. It also pre-empts a likely misinterpretation by explaining that an empty list does not mean the listing is gone.

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

Conciseness3/5

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

Front-loaded with the timeline concept, but it repeats itself: emptiness is explained twice ('empty when nothing changed since the series began' and again 'An empty list means no change...') and the 12-month stale rule is stated both inline in the event list and again as a standalone sentence. Roughly a third of the text is redundant.

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?

With no output schema, the description carries the burden of describing the return value, and it does: newest-first ordering, event type vocabulary, and the empty case. Caching and non-refresh semantics round it out; only explicit alternative-tool routing is absent.

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 description coverage is 100% and both parameters (id, retry_key) are documented in-schema with their source and the five-minute idempotency window. The description adds no additional parameter meaning, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb+resource: a timeline of a listing's repository events, newest first, with the event vocabulary enumerated (abandono, sumiu, renomeado, readme_mudou, manifesto_mudou). An agent can tell it apart from get_listing or listing_status, though the distinction is inferred rather than stated.

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

Usage Guidelines3/5

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

Provides interpretive context (empty list meaning, 15-minute cache, what 'stale' means) but never says when to reach for this versus get_listing, listing_status, or listing_security. Usage is implied by the resource described rather than routed explicitly.

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