What it can do
🧹 Clean Markdown: headings, lists, tables and code blocks, in a structure an LLM reads well.
README.md:106🎯 Fit Markdown: filters remove menus, footers and boilerplate: PruningContentFilterLXML, BM25ContentFilter (for a query) and LLMContentFilter.

What needs
a closer look.
Critical details are withheld publicly for the first 30 days after a scan. A matched pattern is a lead for investigation, not a confirmed vulnerability.
Dependencies: 126 exact runtime versions from uv.lock checked against OSV.dev on Oct 12, 2026; 24 with known advisories. Reachability is not checked.
12 findings
MAJORUnsafe deserialization
Unsafe deserialization
The code loads data with a format that can run code while it is read, such as pickle or unrestricted YAML. A poisoned file, cache entry or downloaded model then runs with the agent's permissions.
Use a data-only format (JSON, safetensors, yaml.safe_load) for anything that is not fully trusted.
MAJORDatabase query built from text
Database query built from text
A SQL statement is assembled by inserting values into the query text. If any of those values comes from a user or from model output, as in text-to-SQL agents, it can rewrite the query.
Pass values as bound parameters and allow-list identifiers such as table and column names.

MAJORModel call without fallback
Model call without fallback
A model call has no visible fallback. If the provider fails or is rate limited, the whole agent fails with it.
Configure a secondary model or explicit fallback path for provider failures.
MAJORDomain ownership not verified
Domain ownership not verified
Metal Mantra could not confirm that the owner controls the stated domain. The domain may belong to someone else.
Verify the domain using the Metal Mantra DNS TXT challenge.
