get_redux_state

Inspect Redux state and recent actions from DevTools or exposed stores, filtering by path to debug React app issues.

Instructions

Inspect Redux store state and recent actions. Works with Redux DevTools or globally exposed stores.

Input Schema

pathNoDot-notation path to specific state slice (e.g., "user.profile")
actionsLimitNoMaximum number of recent actions to return (default: 20)
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It mentions compatibility but does not disclose read-only guarantees, failure modes if no Redux store is found, or any side effects from connecting to DevTools. The word 'Inspect' implies reading, but this is not explicit.

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 every word earns its place. No redundant details or fluff.

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

Completeness3/5

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

For a simple two-parameter read tool, the description covers the core function and compatibility. However, it does not clarify default behavior when path is omitted, nor does it describe the return format, and with no output schema or annotations, some operational detail is missing.

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 both parameters have clear descriptions. The tool description adds no additional parameter semantics beyond what the schema already provides, so the baseline of 3 applies.

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 identifies the tool as inspecting Redux store state and recent actions, with a specific verb and resource. The explicit mention of 'Redux' distinguishes it from sibling tools like get_zustand_stores.

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 states it works with Redux DevTools or globally exposed stores, giving clear context for when to use it. However, it does not explicitly mention alternatives or exclusion criteria, though the Redux-specific wording implies usage when dealing with Redux.

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