Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.00405 |
| Opus 5 | $0.00022 | $0.00202 |
| Sonnet 5 | $0.00009 | $0.00081 |
| Haiku 4.5 | $0.00004 | $0.00040 |
Grade A, and why
i18n-checker 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 8d 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.

Claude Code Tool Invocation
node "${CLAUDE_PLUGIN_ROOT}/../../core/tools/tool-runner.mjs" i18n_validate --path locales/
node "${CLAUDE_PLUGIN_ROOT}/../../core/tools/tool-runner.mjs" code_map --path src/

Language-Aware Hardcoded String Detection
JSX hardcoded string patterns are defined per language in languages/{lang}/spec.mjs → i18nHardcodedRe. The i18n_validate tool checks JSX extensions (jsxExtensions from spec) automatically.
Domain-Specific Anti-Patterns
- Do NOT flag technical strings (CSS classes, HTML attributes, log messages)
- Do NOT flag test fixtures or mock data for i18n
- Do NOT require i18n for developer-facing error messages
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.

i18n-checker is an agent published in the GitHub repository berrzebb/quorum (10 stars, last pushed 4mo ago), licensed MIT. It adds 43 tokens to every session and 405 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 2026-08-31.
