Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00240 |
| Opus 5 | $0.00000 | $0.00120 |
| Sonnet 5 | $0.00000 | $0.00048 |
| Haiku 4.5 | $0.00000 | $0.00024 |
Grade A, and why
java 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 yesterday.
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 it actually says
Java conventions
- Non-blocking only: Kafka/HTTP work via Vert.x
Future<T>; no blocking calls on event loops - Model types are Java 21 records under
model/ - Config via
Env.resolve()— env var →-DNAME→-Dname.dotted(env wins) - Logging: SLF4J; package loggers follow existing
logback.xmllevels (LOG_LEVEL_*env vars)
Testing
- Unit tests mirror package layout under
src/test/java/ - Run
./gradlew testbefore PRs; add tests for non-trivial metric or Kafka client behavior - Do not add tests that only assert obvious behavior
Kafka client notes
- AdminClient only; read-only DESCRIBE ACLs (cluster, topic
*, group*) - Request batching:
KAFKA_CHUNK_COUNT,KAFKA_CHUNK_DELAY_MS - Kafka 2.x:
MAX_TIMESTAMPlistOffsets unsupported — falls back to LATEST (expected WARN once per process)
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.

java is a cursor rule published in the GitHub repository themoah/klag (81 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 240 tokens. 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 2026-08-30.
