distributed-routing-testing SKILL.md skillA
distributed-routing-testing from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Geo-distributed DNS resolution via in-region open resolvers (Shodan/Censys) to detect geo-fenced infrastructure, GSLB-routed backends, and region-specific endpoints invisible from a single vantage point. Use when the target appears to serve different infrastructure per region, when encountering geo-blocking or geo-fencing, or when recon from a single location misses region-locked assets.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Distributed Routing Testing **Activation gate:** Only use this skill when `GEO_RESOLVERS_ENABLED` is set (any value). If unset, do not suggest, reference, or offer geo-distributed resolution. Do not ask the user to enable it. **Credential requirement:** At least one of `SHODAN_API_KEY` or `CENSYS_PAT` must be set. When both are present, `auto` selects Shodan first (cheaper credit cost for this query pattern). ## Concept Some targets use geo-aware authoritative nameservers, GSLB appliances, or geo-fenced edges that return different A/AAAA records depending on where the DNS **resolver** sits. From a single vantage point you only ever see your own region's answer — the target's region-specific infrastructure is invisible. This is orthogonal to IP rotation (`flareprox`/`fireprox`): those change the **egress IP** of an HTTP request; this changes the **vantage point** of a DNS lookup. Open recursive resolvers physically located in different countries act as regional vantage points. Querying the same hostname through resolvers in DE, SG, BR, JP reveals whether the authoritative nameserver hands back different addresses per region. ## When to Use …

How to install
mdr add dreadnode/capabilities/distributed-routing-testing@sha256:443d3c39a8ba82a5The line at the top of this page pins the label git:20260825.9c682d7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
