Conducts hypothesis-driven, evidence-preserving threat hunts with bounded negative conclusions and telemetry-gap handling. Use for hunt hypotheses, scoped offline analysis, or analytic follow-up; not unscoped scanning, malware execution, or generic intelligence summaries.
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
# Cyber Threat Hunting ## **Priority: P0 (CRITICAL)** Preserve provenance and bound every conclusion to authorized evidence. ## Structure Input: falsifiable hypothesis, behavior, entities, scope, sources, window, expected signal, stop condition. Process: define positive/negative observations; normalize without overwriting originals; test narrowest evidence; correlate by entity/time; record gaps and alternatives. Output: status, cited evidence, bounded conclusion, limitations, owner. ## Rules - Active collection or network operations require `cyber-authorization`, documented scope, and runtime-proven controls; unsupported or missing scope blocks execution. - Use controlled synthetic/offline fixtures. Preserve query/version, fixture provenance, retention, clock, identity, and source limitations. - Status is `confirmed`, `suspected`, `false-positive`, `blocked`, or `not-tested`; only cited evidence supports a status. - “No evidence found in the examined dataset/time window” is bounded negative evidence, never proof of no compromise. …

How to install
mdr add hoangnguyen0403/agent-skills-standard/cyber-threat-hunting@sha256:d81d7b4719d77ca6The line at the top of this page pins the label git:20260929.bdf124b, 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.
