vectra-hunt

vectra-hunt is a skill for Claude Code, Codex from vectra-ai-research/vectra-soc-agent-starter. It costs 214 tokens per session (2,976 once invoked), scanned A, original, MIT.

A search and investigation guide for Vectra security metadata. Vectra is a cybersecurity platform, and its metadata can describe network activity such as DNS, HTTP, authentication and cloud events.

In plain words
What is it for?
It is for investigating network and cloud activity, searching for indicators of compromise, checking threat techniques and reporting matches, coverage and gaps.
Why use it?
It helps turn security questions or threat reports into prepared database searches and combine the results into a hunt report.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

vectra-hunt scanned grade A with 0 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vectra Hunt — Metadata Search & Threat-Intel Hunting

This skill is the search and hunt layer over Vectra metadata. It runs in two modes:

Mode Trigger Output Reference
Ad-hoc query "Did host X talk to evil.com last night?", "Find RC4 TGS requests", "Show me POST exfil traffic" Single Investigation Query result, summarized in chat references/mode-ad-hoc.md
TI-driven hunt "Hunt this CISA advisory", "Sweep our tenant for APT-9999", "Are we affected by this Cobalt Strike campaign?" Multi-query sweep + consolidated hunt report (IOC hits, TTP coverage, gaps, recommendations) references/mode-ti-hunt.md

Both modes draw on the same library of pre-validated SQL recipes (catalog below). Ad-hoc mode runs one recipe. TI mode batches many of them around a report's IOCs and TTPs.

This is not:

  • A canned dashboard / KPI report — that's vectra-reports (Python) or vectra-reports-mcp (MCP).
  • A detection-triage playbook ("how do I triage a Smash and Grab?") or queue-triage workflow ("walk me through tier 1") — that's vectra-investigator (loads the matching playbook-<category>.md).

How this skill is organized

The detail for each piece lives in references/ — load only what the current task needs (see references/MANIFEST.md for the required per-mode and per-domain load set; progressive load is mandatory). Two distinct kinds of reference file:

Orchestration / methodology (how to run the skill):

Sub-area Reference
Mode 1 — Ad-hoc workflow + decision guide references/mode-ad-hoc.md
Mode 2 — TI-hunt 6-phase methodology + execution rules references/mode-ti-hunt.md
MITRE TTP & tools/malware → recipe lookup (used by both modes) references/ti-hunt-ttp-map.md
TI Hunt Report markdown template (Phase 6 of TI-hunt) references/ti-hunt-report-template.md
Query Construction Rules (SQL — used when no recipe matches) references/query-construction.md
Table-specific gotchas (per-table quirks to check before authoring) references/table-gotchas.md

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.
