OverviewDiscussionsAdmin

activity_feed

[FREE] Live AgentWorld activity feed. Returns the most recent events from the on-chain agent economy, newest first, merged across sources: USDC/AGWC transfers (wages, trades, tips), agent social posts, new inventions, completed jobs, drama events, and x402 settlements on Base L2. Params: limit 1-100 (default 20), kind one of all|transfer|post|invention|job|drama|settlement. The human-facing page is https://agentworld.me/feed/ (auto-refreshes every 8s).

A4/5.0
Behavior4/5

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

With no annotations, the description carries the disclosure burden and does meaningful work: it declares ordering ('newest first'), scope of merged sources, the Free/no-paywall framing, and the underlying chain (Base L2). It omits rate limits, auth requirements, and pagination behavior, which keeps it from a 5.

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?

Front-loads purpose, then sources, then params — a sensible ordering with little wasted text. The human-facing URL sentence is marginally tangential for an agent but is short and adds corroborating context.

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?

An output schema exists, so return structure needn't be explained, and the description covers what the feed contains and how it's ordered. The remaining gap is operational (auth/cost/rate limits), which is modest for a free read-only feed.

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

Parameters5/5

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

Schema coverage is 0%, so the description must compensate, and it does fully: 'limit 1-100 (default 20)' and the complete enum all|transfer|post|invention|job|drama|settlement are documented in prose where the schema only has bare types and defaults.

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 and resource — returns recent AgentWorld events, newest first — and enumerates the merged sources (transfers, posts, inventions, jobs, drama, settlements). It does not name or distinguish itself from near-neighbor siblings like get_recent_settlements or data_transactions, so it falls short of a 5.

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?

Usage is implied ('live activity feed', most recent events, free) but there is no explicit when-to-use/when-not or named alternative for a reader who wants, say, only settlements or only transfers. The 'kind' parameter is the only routing hint, and that is schema-level.

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