Input Schema

NameRequiredDescriptionDefault
guideYesThe whole new guide; an empty string clears it.
channelYesThe channel whose guide to replace.
on_behalf_ofNoA teammate's email, or an agency client's from list_agency_clients, to run this call in that account: their agents, settings, connected accounts, and credits. Omit it to act on your own account.

A4.6/5.0
Behavior4/5

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

Beyond the readOnlyHint=false annotation, the description discloses that a set guide overrides the communication style stored in memory and that other channels keep their guides, which is meaningful precedence and scope information. It also warns that user-authored or user-approved text is replaced and instructs the agent to report changes. It does not say whether prior guides are recoverable or versioned, which is the main residual gap given destructiveHint=false on an overwriting operation.

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-loaded with the core action, then usage, then the edit procedure, and the returns block is clearly separated. Slightly repetitive around replacement ("It replaces text the user wrote or approved" followed by "keep everything they didn't ask to change"), but no sentence is wasted.

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?

For a three-parameter mutation tool with no output schema, the description covers action, scope isolation, precedence over memory, the required read-modify-write flow, and return contents via the embedded returns block. An agent has enough to call it correctly without further discovery.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning: the guide parameter must be the whole new guide, assembled by reading with get_writing_style_guide and stripping the notes that tool appends. That is a non-obvious input contract the schema does not express.

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 and resource: "Replace the user's writing style guide for one channel, the voice Sliq writes in there." It also names the sibling it pairs with (get_writing_style_guide), so an agent can distinguish a full replacement from a read without opening either schema.

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

Usage Guidelines5/5

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

Gives explicit when-to-use guidance ("when the user wants to sound different in a channel that has a guide, change the guide") and names the alternative plus the exact read-modify-write procedure via get_writing_style_guide. It also states a preservation rule for text the user didn't ask to change.

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