Update Project

update_project

Idempotent

Use this to rename a project, change its color or website url, or archive/unarchive it (archived: true hides it from pickers; its tasks keep the association; archived: false brings it back). Only fields you pass are changed, and the values they replace are kept in the board's journal. Idempotent.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.6/5.0

Behavior5/5

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

Goes well beyond the annotations: it defines the partial-update contract ("Only fields you pass are changed"), the side effects of archival on pickers and task associations, how to reverse it (archived: false), and where old values go (the board's journal). The "Idempotent" claim is consistent with idempotentHint=true and destructiveHint=false.

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

Conciseness5/5

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

Three dense sentences, front-loaded with the use case, then the archive semantics, then the update/journal contract. Every clause carries information; no filler or restatement of the title.

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?

Covers mutation semantics, partial updates, and reversibility for a tool with no output schema and no parameter-level schema docs. It does not state permission/auth requirements or what the call returns, which are the remaining gaps for a write operation.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must carry the load. It explains the semantics of name, color, url, and especially the boolean archived (hide from pickers, tasks keep association, false restores) and the partial-update behavior. It omits any note on the required id or the nullability of url, hence not a 5.

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?

States a specific verb (update) plus the exact mutable fields of the resource: rename, color, website url, archive/unarchive. An agent can distinguish it from create_project, list_projects, and update_task without opening any schema.

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?

"Use this to rename a project, change its color or website url, or archive/unarchive it" gives clear triggering conditions for each mode of use. It does not name a sibling alternative or state when NOT to use it (e.g., use create_project for new projects), so it stops short of full routing guidance.

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