qgis-syntax-plugins is a skill for Claude Code, Codex from Impertio-Studio/QGIS-Claude-Skill-Package. It costs 97 tokens per session (2,460 once invoked), scanned A, original, MIT.

A guide to building QGIS plugins, which are add-ons that extend the desktop mapping and geographic-data application. It covers the files, startup and shutdown steps, user interface integration, and publishing requirements.

In plain words
What is it for?
Use it to create QGIS menus, toolbars, dock panels, and other custom interfaces. It also helps structure plugin files and prepare metadata and resources for publication.
Why use it?
It helps avoid plugins that fail to start, leave menus or signals behind, or do not meet QGIS repository requirements.

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

qgis-syntax-plugins 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 10d 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.

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.
