Create Chained Governance Block

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

The description opens with 'Create a governance block,' a write/mutation framing, while the annotations declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. This is a direct inconsistency about whether the call causes a side effect, so the description undermines rather than supplements the structured metadata. No signing, persistence, or key-handling behavior is described either.

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?

Two short sentences with no filler and the core action front-loaded. Nothing is wasted, though the brevity leaves obvious behavioral questions unanswered that a slightly longer definition could have covered.

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?

With 7 parameters, 5 required, no output schema, and a cryptographic key flow, this definition is too thin. It never says what is returned (a block? an identifier? a receipt), whether anything is persisted, or how parentBlock and the keys are used, so an agent cannot confidently call it from the description alone.

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 71%: content, publicKey, privateKey, parentBlock, and derivationType are documented in the schema, while training and inference are self-describing enums. The description adds no parameter-level meaning (e.g., that privateKey signs the new block, or that parentBlock is the parent JSON), so it neither compensates nor detracts much.

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+resource (create a governance block) and narrows the scope to derivative content that references an original publisher's block, which distinguishes it in spirit from generate_governance_block. It does not name a sibling explicitly, so an agent must still infer the boundary from the phrase 'references the original publisher's block.'

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?

The phrase 'for derivative content that references the original publisher's block' implies the precondition for choosing this tool over a plain block generator. However, no alternatives (generate_governance_block, create_derivation_receipt, create_artifact_provenance) are named, and no when-not guidance or prerequisites for the required keys are given.

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