Arcpy Plan

ArcPy Plan

Create a concrete, step‑by‑step ArcPy plan before writing code. Plans should be grounded in the actual ArcGIS Pro project context.

Intent

Turn a GIS task into a deterministic sequence of ArcPy operations, with inputs, outputs, and checks defined up front.

Inputs

• task_description (string)
• project_path (string, optional)
• map_name (string, optional)
• output_workspace (string, optional)
• constraints (string, optional)

Use arcgispro-cli (preferred)

If available, gather real project context:

• arcgispro layers --json
• arcgispro fields "LayerName"
• arcgispro connections

Use real layer/field names and data sources in the plan.

Output

A plan object with:

• inputs: layers/tables/paths
• steps: ordered ArcPy tools with purpose
• outputs: new datasets + locations
• checks: preflight validations and counts
• risks: destructive operations or performance concerns

Example

User: “Find parcels within 500 ft of schools and export.”

Plan:

1. Validate layers: Parcels, Schools exist
2. Select schools (optional filter)
3. Buffer schools (500 ft) → Schools_Buffer_500
4. Select parcels by location intersecting buffer
5. Export selection to Output.gdb
6. Report counts

Outputs

Return a concise, usable result with the key artifacts or recommendations.

Safety

Do not invent data, credentials, or system context. Flag uncertainty and risky operations clearly.
