cypher-investigation SKILL.md skillA
cypher-investigation from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dreadnode/capabilities/cypher-investigation@git:20260504.2a64374Pins git:20260504.2a64374 in mdr.lock. Pin the fingerprint instead.

Open-ended graph investigation via raw OpenCypher queries. Use when the prebuilt tools don't capture the question — bespoke "find every X that can reach Y via Z" queries, ad-hoc relationship walks, novel attack-path patterns, or one-off exports for analysis. Read-only by default; writes require explicit opt-in.
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
# Cypher investigation The pre-built BHE endpoints answer most common questions, but the graph holds far more than they expose. Cypher is the escape hatch — a query language that walks nodes and edges arbitrarily — and `run_cypher` is the tool that lets the agent ask anything. The cost of that flexibility is that bad queries can either drown the session in results or accidentally mutate state. This skill walks the agent through the discipline of writing safe, scoped, useful Cypher. ## Preconditions `bhe-bootstrap` has run. ## Workflow ### 1. Reach for prebuilt tools first Before writing Cypher, check whether the question maps to one of the dedicated tools: - "Who has admin on this computer?" → `computer_admins`. - "What does this user have RDP on?" → `user_admin_rights(kind="rdp-rights")`. - "What attack paths are active in this domain?" → `domain_attack_paths`. - "Who is in this asset group tag?" → `list_tag_members`. Use Cypher only when the answer needs a graph traversal the prebuilt tools don't cover. ### 2. Browse the saved-query library …

How to install
mdr add dreadnode/capabilities/cypher-investigation@sha256:52f870f36e9fb065The line at the top of this page pins the label git:20260504.2a64374, 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.
