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.

SkillSpector: 2 findings, up to critical
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- critical YARA Match · line 61 YARA rule matched a known malware signature (reverse shell, backdoor, ransomware, C2 framework, or info stealer).Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.
- medium Data Exfiltration · line 36 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00103 | $0.01457 |
| Opus 5 | $0.00051 | $0.00728 |
| Sonnet 5 | $0.00021 | $0.00291 |
| Haiku 4.5 | $0.00010 | $0.00146 |
Grade A, and why
jndi-map scanned grade A with 1 finding 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.

JNDIMap
Use this skill to help with JNDIMap setup, documentation lookup, command construction, URL format selection, protocol configuration, module selection, and troubleshooting. JNDIMap supports LDAP, RMI, and LDAPS services, Basic payloads, BeanFactory bypasses, JDBC-related payloads, LDAP deserialization, Hessian, Tomcat XXE, custom scripts, and advanced runtime options.
Start Here
- Check the local runtime before giving run commands:
- JNDIMap is recommended for JDK 8 or newer.
- Run
java -versionwhen the user wants to execute JNDIMap locally. - If Java is missing or older than Java 8, explain that JDK 8+ is required before running the jar.
- Ensure the JNDIMap jar exists before using it.
- Look for
scripts/JNDIMap*.jar. - Treat
scripts/as empty if it only contains placeholder files such as.gitkeep. - On first use, if no JNDIMap jar is present, automatically download the latest release jar from
https://github.com/X1r0z/JNDIMap/releases/latestintoscripts/.
- Look for
First-Use Setup
When scripts/ has no JNDIMap*.jar, download the latest release asset whose name matches JNDIMap*.jar.
Use this approach from the skill directory:
mkdir -p scripts
asset_url="$(curl -s https://api.github.com/repos/X1r0z/JNDIMap/releases/latest | sed -n 's/.*"browser_download_url": "\(.*JNDIMap[^"]*\.jar\)".*/\1/p' | head -n 1)"
test -n "$asset_url"
curl -L "$asset_url" -o "scripts/$(basename "$asset_url")"
After downloading, use the discovered jar path in later commands:
jar_path="$(find scripts -maxdepth 1 -type f -name 'JNDIMap*.jar' | sort | tail -n 1)"
java -jar "$jar_path" -h
Documentation Selection
Read only the document section relevant to the user's task.
Prefer Chinese references for Chinese conversations and English references for English conversations.
- General overview, features, compile notes, and quick start:
references/README.mdorreferences/README.en.md - CLI flags, ports, URL format, payload categories, bypasses, JDBC, deserialization, scripts, and advanced options:
references/USAGE.mdorreferences/USAGE.en.md
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 10d ago First seen · 120 lines · 103 tokens per session scan A a8e0c69b7f86
jndi-map is a skill published in the GitHub repository X1r0z/JNDIMap (601 stars, last pushed 4mo ago), licensed MIT. It adds 103 tokens to every session and 1,457 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
