This skill should be used when the user asks to "convert this shapefile to SQL", "show me the MongoDB inserts for this geodatabase", "give me the PostGIS DDL for this DWG", "translate this GIS file to JSON I can paste into Mongo", or invokes `/gis-to-db:convert <file>`. Parses a GIS or CAD file inline using fiona/ezdxf/LibreDWG (host or Docker), then prints ready-to-execute SQL inserts (PostGIS or MySQL spatial) or MongoDB documents directly into the chat. Does NOT write to a database — the user can copy the output, review, and run themselves.

This skill should be used when the user asks to "publish the cadastre", "generate a public-facing parcel map", "create a parcel lookup API", "produce official extract PDF", "publish land registry to the web", "generate cadastre change log", "public cadastre publication", or invokes `/civic-gis:cadastral-publish`. Takes an official cadastral dataset (typically the output of `gis-to-db:convert` to PostGIS or MongoDB) and produces public-facing artifacts: a searchable Leaflet map, parcel-extract PDF templates, JSON API stubs, and a change log against the previous publication.

This skill should be used when the user discusses municipal or civic GIS work — terms like "zoning ordinance", "setback", "FAR (floor area ratio)", "lot coverage", "building permit", "use permit", "variance", "rezoning", "master plan", "cadastre", "parcel ID", "deed", "title", "land registry", "PIN" (Parcel Identification Number), "tax map", "ROW (right of way)", "easement", "land-use code", "comprehensive plan", "subdivision", "plat", "TIF (tax increment financing)", "opportunity zone", "enterprise zone", "investment incentive", "economic development", "investor profile", "site selection", "small town economic development", "post-conflict reconstruction", "damage assessment", "displaced persons", "property restitution", or asks about civic / municipal / governmental geospatial workflows in any country (US, Europe, MENA, etc.). Provides terminology, data-source references, ruleset patterns, and cross-jurisdiction guidance.

This skill should be used when the user asks to "generate an investor profile for this town", "create an economic development pitch", "show investor metrics for city X", "what would investors want to know about this town", "build an investment one-pager", "town profile for site selection", "economic development brief", or invokes `/civic-gis:investment-profile`. Generates an investor-ready profile of a small city or town: demographics, infrastructure, available land, key industries, incentives, comparable cities. Pulls from user-supplied data and free public sources. Outputs markdown, JSON, or a one-page PDF brief.

This skill should be used when the user asks to "find suitable sites for this investment", "match a proposed investment to parcels", "where could this factory go in this town", "show me parcels matching these criteria", "site selection for X industry", "investment site matching", or invokes `/civic-gis:investment-sites`. Filters a town's parcel inventory against an investment brief (industry, size, budget, requirements) and returns ranked candidate sites with concrete rationale. Composes on top of gis-to-db's analyze-site rule engine.

This skill should be used when the user asks to "monitor land use changes", "detect unauthorized changes in land use", "compare current land use against the master plan", "land use change detection", "flag illegal conversions", "track parcel use over time", "land use compliance monitoring", or invokes `/civic-gis:landuse-monitor`. Periodically compares the current land-use snapshot against an approved master plan AND against the previous snapshot, flags both unauthorized changes (current ≠ master plan) and recent changes (current ≠ previous snapshot). Composes on top of gis-to-db:analyze-diff.

This skill should be used when the user asks to "check if this project complies with zoning", "validate a building permit application", "does this proposal meet setback requirements", "check zoning rules for site X", "permit compliance check", "is this project allowed in zone Y", or invokes `/civic-gis:permit-check`. Scores a proposed project (location + building parameters) against a jurisdiction's zoning ruleset and reports violations with citations. Rule-based and transparent — produces a per-rule pass/fail report, never a black-box decision.

This skill should be used when the user asks to "track reconstruction progress", "compare pre-conflict vs current cadastre", "damage assessment for this area", "find destroyed buildings", "post-conflict reconstruction monitoring", "map damaged parcels", "show reconstruction status", or invokes `/civic-gis:reconstruction-tracker`. Compares a pre-event cadastre baseline (parcels + buildings before conflict / disaster) with a post-event survey or remote-sensing layer, classifies each parcel as intact / damaged / destroyed / rebuilt, and produces a per-parcel status report plus aggregate statistics. Composes on top of gis-to-db:analyze-diff.
