spatial_markov

Compute a Markov chain on spatial panel data from a shapefile to analyze regional transitions over time and spatial dependence.

Behavior2/5

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

No annotations provided, and the description only states it 'runs' the analysis without disclosing side effects, data validation steps, or what happens with invalid inputs. Behavioral transparency is minimal.

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 description is a single sentence of 15 words, which is very concise. However, it omits necessary details for parameter and usage context, slightly reducing its effectiveness.

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

Completeness2/5

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

Given the tool's complexity (12 parameters, spatial econometrics), the description lacks essential context about output, prerequisites, and how parameters affect analysis. Output schema exists but is unmentioned.

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

Parameters1/5

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

With 0% schema description coverage and no parameter explanations in the description, the agent gains no insight into critical parameters like weights_method, k, m, or permutations. This is a severe deficiency.

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 runs a 'giddy Spatial Markov' analysis on panel data from a shapefile, specifying the input format and type of analysis. This distinguishes it from sibling tools like morans_i or gearys_c.

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 description does not explicitly state when to use this tool versus alternatives like other spatial statistics. While it mentions Spatial Markov, it lacks guidance on appropriate conditions or comparisons.

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