alltrails_get_activity_feed

Read-only

Get an AllTrails user's activity feed (recorded hikes and posts). Specify a userId for a public profile, or pass a feed type to retrieve items instead of the feed directory.

Instructions

Get an AllTrails user's activity feed (recorded hikes and posts). Defaults to the signed-in user; pass a userId to target a specific public profile. Without a feed argument this returns the feed DIRECTORY (the available feeds: local, timeline (following), personal (own posts)) — pass feed to get the actual items. Returns slim projections by default; pass view:"full" for the whole records.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
feedNoWhich feed to read: local (nearby activity), timeline (people you follow), personal (own posts). Omit to list the available feeds.
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact returns { count, hasNextPage, nextCursor, items: [{ type, timestamp, description, user, trail, activity, review }] } — and the no-feed directory as { name, displayName } per feed; "full" returns AllTrails' whole records.
cursorNoOpaque nextCursor from a previous page, for pagination
userIdNoNumeric AllTrails user id. Defaults to the signed-in user.
maxItemsNoMax items per page (server-side)

TDQS

A3.9/5.0
Behavior4/5

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

The readOnlyHint annotation already establishes safety, and the description adds meaningful non-obvious behavior beyond it: the dual-mode response (directory vs actual items), the default-to-signed-in-user behavior, and the slim-versus-full projection switch. No contradiction with the annotation.

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?

Three compact sentences, front-loaded with the purpose, with every sentence earning its place (purpose, target resolution, dual-mode behavior, projection behavior). No fluff or repetition of schema content.

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 5-parameter tool with no output schema, the description covers the essential decision points: how to select a feed, how to target a user, and how the view parameter changes the response. Combined with the 100% schema coverage, an agent has what it needs to invoke correctly.

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 carries a description, so the baseline is 3. The tool description does add connective value by explaining the feed omission-to-directory behavior and the view projection default, but the schema already documents the enum values and response shapes in detail, so the description adds limited extra meaning.

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?

The description opens with a specific verb-plus-resource statement ('Get an AllTrails user's activity feed (recorded hikes and posts)') that clearly delimits the scope. It additionally clarifies the target resolution (signed-in user vs userId), which helps distinguish it from the sibling trail/GPX/list tools, though it never names an alternative explicitly.

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?

The description gives explicit conditional invocation context: omitting 'feed' returns the feed directory, passing 'feed' returns items, and userId defaults to the signed-in user. This is clear usage context with no ambiguity, though it offers no exclusions or named alternatives among the sibling tools.

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