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 5.1 | $0.00049 | $0.02820 |
| Opus 5 | $0.00024 | $0.01410 |
| Sonnet 5 | $0.00010 | $0.00564 |
| Haiku 4.5 | $0.00005 | $0.00282 |
Grade A, and why
unauthorized-access-common-services 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 6d 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.

SKILL: Unauthorized Access to Common Services — Expert Attack Playbook
AI LOAD INSTRUCTION: Expert techniques for exploiting unauthenticated or weakly authenticated management services. Covers Redis write-to-RCE, Rsync data theft, PHP-FPM code execution, Ghostcat AJP file read, Hadoop YARN job submission, and H2 Console JNDI. These are infrastructure-level findings distinct from web application vulnerabilities.
0. RELATED ROUTING
- ssrf-server-side-request-forgery when these services are reachable via SSRF (e.g., SSRF → Redis)
- jndi-injection when H2 Console or similar accepts JNDI connection strings
- deserialization-insecure when RMI Registry or T3 protocol is exposed
- network-protocol-attacks for layer 2/3 attacks during service enumeration
- reverse-shell-techniques for shell payloads after gaining command execution

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.

unauthorized-access-common-services is a skill published in the GitHub repository JustineDevs/premortem (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 49 tokens to every session and 2,820 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to unauthorized-access-common-services, differing in 0 lines, and is treated as a copy.
