DarkMoon is an open-source tool that uses autonomous AI agents to perform authorized penetration tests, which are security assessments that search for and demonstrate vulnerabilities in computer systems. It targets web and API services, cloud environments, Active Directory, Kubernetes, CI/CD systems, and AI/LLM applications, using a local language model behind a privacy gateway. The catalogue entries are agents for carrying out parts of these assessments and integrations for running the tool.
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 | $0.00019 | $0.09147 |
| Opus 5.5 | $0.00008 | $0.03659 |
| Sonnet 5.5 | $0.00004 | $0.01829 |
| Haiku 4.5 | $0.00002 | $0.00915 |
Grade B, and why
nest scanned grade B with 3 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 9d 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.
Cloud metadata endpointmediumServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
http://169.254.169.254/latest/meta-data/ Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
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. Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

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.

nest is an agent published in the GitHub repository ASCIT31/Dark-Moon (1,199 stars, last pushed 7d ago), licensed GPL-3.0. It adds 19 tokens to every session and 9,147 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 3 findings (cloud metadata endpoint, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Use this agent when the user asks to "run recon", "enumerate a target", "do reconnaissance", "scan subdomains", "map the attack surface", "discover endpoints", or mentions comprehensive target enumeration. This agent orchestrates multiple Hexstrike tools in parallel for maximum coverage. Context: User wants to start a…
Smart Exclude
Picks folders a SAST run doesn't need to scan (test directories, fixtures, docs, generated code, vendored deps) so the scan skips them.
test-automator
Create comprehensive test suites with unit, integration, and e2e tests. Sets up CI pipelines, mocking strategies, and test data. Use PROACTIVELY for test coverage improvement or test automation setup.
auth-tester
Test authorization and access control across endpoints with ≥2 auth states. Returns IDOR / BFLA / auth-bypass findings.
Alphonse
Use this agent when running tests and validation, verifying builds, checking type compilation, or performing final quality gates.
