jmix-verify-api-symbol

jmix-verify-api-symbol is a skill for Claude Code, Codex from jmix-framework/jmix-agent-toolkit. It costs 99 tokens per session (1,676 once invoked), scanned A, original, no licence file.

A verification guide for checking that Jmix and Java classes, methods, events, enum values, and icon names actually exist in the current project before using them.

In plain words
What is it for?
Use it before writing code that depends on an unfamiliar Jmix API symbol, especially when project documentation or a connected codebase can confirm its definition.
Why use it?
It prevents errors caused by guessed class names, package paths, event types, methods, or icon constants.

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

jmix-verify-api-symbol 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 1mo 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.

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.
