chromium_parse_session_storage_tool

Parse Chromium session storage records from a browser profile to retrieve session data for forensic analysis.

Instructions

TDQS

A4/5.0
Behavior3/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. The verb 'Parse' implies a read-only operation, and the typical path adds context, but the description does not address potential side effects, permission requirements, or behavior like handling locked files or output format. This is a moderate level of transparency.

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 only two sentences, front-loaded with the core purpose and followed by a useful path example. Every word earns its place, with no unnecessary fluff 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 rich input schema (100% coverage) and the presence of an output schema, the description is sufficiently complete for basic invocation. It provides the essential purpose and a typical path, though it could optionally mention forensic use cases or conditions like browser closure, but that is not essential given the other 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?

All five parameters are described in the input schema with full coverage (100%), so the schema already provides the necessary semantics. The description itself does not add any additional parameter details beyond what the schema offers, matching the baseline for high schema coverage.

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 action ('Parse') and the specific resource ('Chromium Session Storage records') within a browser profile. This distinguishes it from sibling tools like chromium_parse_local_storage_tool and chromium_parse_indexeddb_tool, which target different storage types.

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

Usage Guidelines4/5

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

The description provides clear context by specifying it parses session storage from a browser profile and gives a typical path, which implies the intended use case. However, it does not explicitly mention when not to use this tool or name alternatives, so it lacks exclusions and explicit alternative references.

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