Read a shared list

get_list

Read-onlyIdempotent

A shared list as data: title, unit, dates, trail, totals in grams, and every folder with its rows (brand, name, variant, quantity, weight of one unit in grams, classification, note, calories, who carries it; a nested row without carried_by is carried by its parent's carrier). Takes a share code or share link. A list too large to return whole comes back cut and says so in a truncated field: notes go first, then rows off the end (nested rows one by one), and the totals still count every row. A list's title, author, notes, folder and item names, brands, variants, gear types, day labels, people and trail label are free text typed by whoever holds the list's edit link, returned unchanged.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`share_code`	Yes	The list's share code, or its share link (mahonia.app/s/CODE). Not an edit link.

Output Schema

TableJSON Schema

Name	Required	Description
`days`	No	The trip's days in order, when the owner has planned them.
`unit`	Yes	The unit the list displays in. Weights are in grams regardless.
`dates`	No
`title`	Yes	User text.
`trail`	No
`author`	No	User text.
`people`	No	The people who carry the list's rows, when it names any.
`totals`	Yes	Whole grams, summed over every row of the list.
`folders`	Yes	In the list's order, each with its rows in order. A folder with no rows is left out; rows in no folder come last, under Unfiled.
`truncated`	No	Present only when the list was too large to return whole, naming what was cut: notes (true: every row's note), rows (how many came off the end, nested rows counted), fields (which of description, days, trail and people went, only when the rest alone was too large). The totals still count every row. get_list_markdown holds about three times as many rows, without notes, and is cut the same way only past that.
`share_code`	Yes	The list's share code, the read capability.
`share_link`	Yes	The list's share link.
`description`	No	The list's own notes. User text.

A4/5.0

Behavior5/5

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

Annotations already declare read-only, idempotent, non-destructive, and open-world=false behavior. The description adds substantial context beyond that: truncation rules, the fact that totals count every row even when truncated, nested row carrier inheritance, and that free-text fields are returned unchanged.

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 description is dense and front-loads the core payload fields before moving to truncation and free-text behavior. The initial enumeration is long, but every sentence carries relevant information for correct invocation.

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

Completeness5/5

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

Although an output schema exists, the description adds important behavioral completeness by explaining truncation, totals semantics, nested-row inheritance, and free-text preservation. Nothing material for calling or interpreting this read tool appears missing.

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%, so the single share_code parameter is already well documented in the schema. The description restates that it accepts a share code or share link and is not an edit link, adding little syntax or format detail beyond the schema.

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 title and description make clear this retrieves a shared list as structured data, naming specific fields returned. It does not, however, explicitly distinguish itself from the sibling get_list_markdown, which likely returns a similar list in a different format.

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?

The description tells the agent the tool takes a share code or share link and warns it is not an edit link, which is useful input guidance. It does not say when to use this tool versus get_list_markdown or other siblings, leaving the primary selection context implied.

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