apply_tracker_update

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

With no annotations, the description carries the transparency burden and does convey the key conditional behavior: the append occurs only when the two fingerprints match and no duplicate exists. It does not disclose what happens on mismatch/duplicate (error vs no-op), return value, or side effects beyond append.

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 sentence that is front-loaded with the action and quickly states the two guarding conditions. There is no filler or repetition of schema content.

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?

Given a required nested candidate object, zero annotations, and no output schema, the description is too minimal to fully support a correct call. It explains neither candidate semantics nor expected outcomes for failed checks, and does not place the tool in the propose/apply workflow beyond 'approved'.

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 0%, and the description only loosely maps tracker_sha256 and proposal_sha256 to 'tracker fingerprint' and 'proposal fingerprint'. The candidate object, which is complex and required, receives no explanation of its fields or how it relates to an approved proposal.

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 conditional operation: appending an approved proposal, guarded by fingerprint matching and duplicate checking. The phrase 'approved proposal' hints at distinction from propose_tracker_update, though it does not name the sibling 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?

Implies this tool is for applying already-approved proposals, and the stated match/no-duplicate conditions describe when the append can happen. However, it never tells an agent when to choose this over propose_tracker_update or the other siblings, leaving the selection largely implicit.

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