Inspect raw blocks

portal_debug_query_blocks

Read-only

Query raw block records for EVM, Solana, or Bitcoin to debug Portal coverage, inspect block-level fields, or retrieve raw blocks without transaction or log details.

Instructions

ADVANCED: Query raw block records directly for EVM, Solana, or Bitcoin.

COMMON USER ASKS:

Recent Base blocks

WHEN TO USE:

You are debugging Portal coverage or block-level fields.
You need raw block records instead of transactions, logs, or summaries.

DON'T USE:

You are answering a normal end-user question; prefer recent activity, time series, or raw transaction tools first.

EXAMPLES:

Recent Base blocks: {"network":"base-mainnet","timeframe":"1h","limit":5}

First observedv0.7.9Jun 25, 2026

TDQS

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnly=true and destructive=false, low'ering the bar. The description adds useful behavioral context: it is an ADVANCED debugging tool, queries raw block records, and covers multiple chains. It also clarifies the result is block records rather than transaction-level or summmary data, which is behavioral and return-type information beyond the annotations.

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 organized into labeled sections, front-loaded with the ADVANCED warning and core purpose. Common asks, when-to-use, don't-use, and examples each earn their place without fluf. It is longer than average but structured so an agent can scan quickly.

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

Completeness5/5

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

Given 11 parameters, zero required, 100% schema coverage, and an output schema, the description supplies the missing selection-level context: when to choose this debugging tool over all siblings, what raw blocks are, and how to build a typical query. An agent has enough to select and invoke it correctly.

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

Parameters4/5

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

Schema description coverage is 100%, so parameter semantics are already well documented. The description adds an example ('Recent Base blocks: {"network":"base-mainnet","timeframe":"1h","limit":5}') that demonstrates how typical parameters combine, and it names the three block-chain contexts. This is meaningful added value above the schema, though it does not need to restate every parameter.

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 the tool's action and resource: 'Query raw block records directly for EVM, Solana, or Bitcoin.' It differentiates from sibling tools by emphasizing raw block records rather than transactions, logs, or summaries, which is a meaningful distinction. The title 'Inspect raw blocks' reinforces this without ambiguity.

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?

WHEN TO USE and DON'T USE sections provide explicit guidance. It says to use when debugging Portal coverage or block-level fields and to avoid when answering normal end-user questions, routing the agent toward recent activity, time series, or raw transaction tools instead. This is exemplary alternative-selection guidance.

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