Review smart contract activity

portal_evm_get_contract_activity

Read-only

Summarize a specific contract's recent on-chain activity: interaction volume, unique callers, and event logs. Get a contract-level snapshot of what the contract has been doing on an EVM network.

Instructions

Summarize what one specific contract has been doing lately, including recent interactions, unique callers, and optional event activity.

COMMON USER ASKS:

Contract activity snapshot

FIRST CHOICE FOR:

what one specific contract has been doing lately on an EVM network

WHEN TO USE:

You want to ask "what has this contract been doing?" and get a contract-level answer.
You want a contract-centric activity summary instead of raw records.
You need top callers and interaction volume for one contract.

DON'T USE:

You need the underlying raw logs or transactions.
You want general recent network activity without naming one contract.

EXAMPLES:

Contract activity snapshot: {"network":"base-mainnet","contract_address":"0xabc...","timeframe":"24h"}

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, covering the safety profile. The description adds value beyond that by disclosing the tool's aggregate behavior: it returns a summary with unique callers, interaction volume, and optional event activity rather than raw records. This sets accurate expectations about output shape and analytic nature. No contradiction with annotations.

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?

The definition uses a clear lead sentence followed by scannable labeled sections (COMMON USER ASKS, FIRST CHOICE FOR, WHEN TO USE, DON'T USE, EXAMPLES), with the core purpose front-loaded. It is longer than minimal, and COMMON USER ASKS partially overlaps with FIRST CHOICE FOR, but each section earns its place by making routing and invocation faster for the agent.

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?

For a tool with 7 parameters, an output schema, and rich annotations, the description is thorough: it covers intended use cases, exclusions, and provides a concrete example with the required parameters. The main gaps are tool-level context about mode semantics (fast vs deep) and timeframe block-count behavior, but these are already documented in the parameter schema descriptions, so the description need not repeat them.

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 description coverage is 100%, so the schema carries the parameter documentation burden. The description's example call {'network':'base-mainnet','contract_address':'0xabc...','timeframe':'24h'} reinforces realistic usage and that timeframe accepts formats like '24h' (already documented in the schema). It also maps 'optional event activity' to include_events. This is marginal added value on top of complete schema descriptions, so the baseline 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 opens with a specific verb+resource: 'Summarize what one specific contract has been doing lately, including recent interactions, unique callers, and optional event activity.' It names the unit of analysis (one specific contract) and what distinguishes it from siblings (a contract-level summary, not raw records). The DON'T USE section explicitly steers away from raw logs and transactions, which differentiates it from portal_evm_query_logs and portal_evm_query_transactions.

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?

The WHEN TO USE section lists three concrete conditions (contract-level answer, contract-centric summary instead of raw records, top callers and interaction volume) and the DON'T USE section lists two exclusions (raw logs/transactions, general network activity without a specific contract). These conditions map cleanly onto sibling alternatives: query_logs/query_transactions for raw records and get_recent_activity for general network activity. The guidance is explicit and decision-ready.

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