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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, covering the safety profile. The description adds the useful atomicity guarantee, but says nothing about what the destructive publish replaces, version-conflict failure behavior, or auth requirements.

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

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

A single front-loaded sentence with zero filler. However, for a destructive, 7-parameter commit operation it is arguably too terse, leaving no room for the operational context the tool warrants.

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

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

This is a destructive, non-idempotent-by-default mutation in a multi-step sync lifecycle, with no output schema and no explanation of the begin/append/seal/commit sequence or failure modes. An agent has to reconstruct the workflow entirely from sibling tool names.

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

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

Schema description coverage is 86%, so the schema documents nearly all parameters (including the version guard and idempotency key semantics). The description adds no parameter-level meaning, which is acceptable at this coverage level.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('publish') and resource ('sealed hosted graph version') with a meaningful qualifier ('atomically'). An agent can infer this is the terminal step of a seal/commit flow distinct from seal_project_sync, though the description never names that sibling relationship explicitly.

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

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

There is no when-to-use guidance, no prerequisites, and no alternatives named. The word 'sealed' hints that a sealing step must precede this, but the agent is left to infer the sequencing from sibling names alone.

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