A4/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the write nature is known. The description adds key context by stating the tool returns an unsigned transaction hex for signing, which is not covered by annotations. No contradiction.

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?

The description is a single, front-loaded sentence that communicates the action, scope, and return type without unnecessary words or repetition.

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?

Given the tool's moderate complexity and the presence of rich annotations and full schema descriptions, the description covers the essential behavioral aspect (returning an unsigned transaction hex) and the domain (Stake 2.0). It does not over-explain details already present in structured fields.

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

Parameters3/5

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

Schema coverage is 100% and each parameter is already described with type and purpose. The description adds no extra parameter-specific meaning beyond the schema, so the baseline score of 3 is appropriate.

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?

The description clearly states a specific action ('Reclaim') and resource ('delegated energy or bandwidth'), plus the Stake 2.0 context. This distinguishes it from the sibling tool 'delegate_resource' and from legacy 'unfreeze_balance'.

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

Usage Guidelines3/5

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

The phrase 'previously delegated' implies when to use this tool, but it does not explicitly mention alternatives or when not to use it. There is no comparative guidance against 'unfreeze_balance' or 'delegate_resource'.

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

B3.2/5.0
Disambiguation3/5

Several tool groups have overlapping responsibilities (e.g., get_energy_prices/get_bandwidth_prices/get_chain_parameters, get_pending_transactions/get_pending_by_address/is_transaction_pending, and analyze_account vs get_account plus its resource/permission variants). These create boundary confusion despite clear descriptions, and with 43 tools an agent will likely select the wrong one occasionally.

Naming Consistency5/5

All tools follow a consistent snake_case verb_noun pattern (e.g., get_account, transfer_trx, delegate_resource, unfreeze_balance). Even the few multi-word verbs (estimate_energy, trigger_constant_contract) remain predictable. No camelCase or inconsistent verb styles.

Tool Count2/5

With 43 tools, the server is heavy. While the TRON domain is broad, the tool surface is bloated with many near-synonyms and split functionalities that could be consolidated. The rubric flags 25+ tools as too many; 43 clearly exceeds that.

Completeness3/5

The server covers a wide range of read and transaction-building operations, including staking, governance, contracts, and TRC20. However, it lacks critical lifecycle steps: there is no sign or broadcast tool, and no ability to deploy contracts or create accounts. This is a significant gap for a tool that returns unsigned transactions.
