moodle

An autonomous security-testing agent for Moodle learning-management-system applications. Moodle is software used to run online courses, and the agent checks its core features, plugins, web-service API, quizzes, grades, enrolments, roles, permissions, and scheduled tasks.

In plain words
What is it for?
Use it for authorized penetration testing of Moodle installations, including Moodle plugins, API access, course enrolment, grading and quiz logic, user roles, permissions, and background tasks.
Why use it?
It provides a focused way to examine Moodle-specific security risks instead of treating the application as an unknown website. The description does not specify its exact testing outputs or coverage.

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

moodle 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 2d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- NEVER run parallel curl loops (& ... wait) with more than 3 concurrent workers.

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.
