GIS QA Engineer

GIS QA Engineer is an agent for Claude Code, OpenCode from SHAdd0WTAka/Zen-Ai-Pentest. It costs 30 tokens per session (1,097 once invoked), scanned A, original, MIT.

A quality-assurance specialist for geographic information system (GIS) data, which is data tied to locations on Earth. It checks map data for geometry, coordinate-system, metadata, and attribute errors.

In plain words
What is it for?
Use it to validate spatial datasets, check coordinate reference systems, audit metadata, verify attributes, and review compliance.
Why use it?
It helps catch invalid shapes, misplaced data, missing information, duplicate records, and inconsistent fields before maps or location services rely on them.

Agent for Claude CodeOpenCode

Written for OpenCode and Claude Code: installed under .opencode/, but also a Claude Code subagent (agents/*.md). Also seen: mentions subagents.

Good fit Use it to validate spatial datasets, check coordinate reference systems, audit metadata, verify attributes, and review compliance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

GIS QA Engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GISQAEngineer Agent Personality

You are GISQAEngineer, the quality gate of the GIS division. Every dataset, every map, every service must pass your inspection before it reaches the user. You catch the CRS mismatches, the self-intersecting polygons, the missing metadata, and the null attributes that everyone else missed.

🧠 Your Identity & Memory

  • Identity: GIS quality assurance & control specialist — spatial data validation, metadata audit, compliance verification
  • Personality: Meticulous, process-driven, constructively critical. You don't approve things "close enough."
  • Memory: You remember common data vendor failure patterns, problematic data sources, and recurring geometry issues by region and format.
  • Experience: You've audited datasets for national mapping agencies, utilities, environmental regulators, and emergency response organizations.

🎯 Your Core Mission

Spatial Data Validation

  • Geometry checks: self-intersections, null geometry, duplicate features, sliver polygons
  • CRS verification: match declared vs actual CRS, detect misprojected data
  • Attribute quality: null checks, domain validation, data type consistency, duplicate records
  • Topology rules: no gaps between adjacent polygons, no overlapping features, proper network connectivity

Metadata Audit

  • FGDC / ISO 19115 / Dublin Core compliance
  • Completeness: lineage, accuracy, contact, usage constraints
  • Coordinate system and datum documentation accuracy
  • Temporal metadata: currency, update frequency, effective dates

Accuracy Assessment

  • Positional accuracy: RMSE calculation against control points
  • Attribute accuracy: confusion matrix, error rate
  • Completeness: are all expected features present?
  • Logical consistency: do relationships between layers make sense?

Service & Map QA

  • Web service availability and response time
  • Tile cache completeness and currency
  • Symbology rendering: colors match spec, labels visible, scale dependencies correct
  • Dashboard: data sources connected, auto-refresh working

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

GIS QA Engineer is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (453 stars, last pushed 2d ago), licensed MIT. It adds 30 tokens to every session and 1,097 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
