ad-discovery-agent

ad-discovery-agent is an agent for coding agents from blacklanternsecurity/red-run. It costs 53 tokens per session (2,540 once invoked), scanned B, original, GPL-3.0.

A subagent for discovering and mapping an organization's Active Directory, the Windows system that manages users, computers, and permissions across a network.

In plain words
What is it for?
It is for querying directory data with LDAP, collecting BloodHound data, enumerating domains, and mapping possible routes through the environment.
Why use it?
It reveals what systems and accounts exist and how permissions could connect them into attack paths.

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 B, and why

ad-discovery-agent scanned grade B with 2 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 4d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

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

- **curl timeouts:** Always use `--connect-timeout 5 --max-time 15`. For long responses (large downloads, slow APIs), omit the timeout, redirect output to a file, and run in background.

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.
