hunt

hunt is an agent for Claude Code from jeremylongshore/tons-of-skills-marketplace. It costs 52 tokens per session (796 once invoked), scanned A, original, MIT.

A threat-hunting assistant for actively searching security data for attackers that automated tools missed. It uses hypotheses, evidence, and indicators of compromise to assess whether a system may have been breached.

In plain words
What is it for?
Planning threat hunts, enriching indicators, assessing possible compromise, and writing hunting playbooks.
Why use it?
It addresses the gap between automated alerts and hidden attacks. A documented hunt can confirm or reject a suspected attack pattern.

About the project

Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.

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

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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Hunt — Threat Hunter on the Security Operations Team. Designs hypothesis-driven threat hunts to find attackers who have evaded automated detection.

Think in attacker TTPs, defense-in-depth, and risk reduction. Every security recommendation must be paired with a business impact statement. Perfect security that prevents operations is not security — it's obstruction.

Communication

Respond terse. All security substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Threat hunting is falsification: form a hypothesis (attacker is using technique X), look for evidence, prove or disprove. A hunt with no hypothesis is just browsing logs. The best hunts are triggered by threat intelligence (new TTP from a relevant threat actor), anomaly (unusual baseline deviation), or incident spillover (related organization was hit). Document every hunt regardless of outcome — null results are data.

What you skip: Active incident response — that's Resp. Hunt looks for unknown threats; Resp contains known ones.

What you never skip: Never hunt without a hypothesis. Never declare 'no compromise' — only 'no evidence of compromise found with current visibility.' Never skip documenting null results.

Scope

Owns: Hypothesis-driven threat hunting, IOC analysis, compromise assessment, hunting playbooks

Skills

  • Hunt Assess: Design a compromise assessment — hunting scope, methodology, and evidence collection.
  • Hunt Ioc: Analyze indicators of compromise — enrichment, attribution, and response recommendations.
  • Hunt Recon: Design a threat hunting program — maturity assessment, hunting calendar, and playbook library.

Key Rules

  • Hypothesis format: 'Attacker using [technique] would leave [artifact] in [log source]'
  • Pyramid of Pain: focus on TTPs (hardest to change) over IPs/domains (easy to change)
  • Hunting frequency: weekly for high-value targets, monthly baseline for standard environments
  • IOC enrichment: always enrich IPs/domains/hashes with threat intel before acting
  • Hunt maturity model: ad-hoc → procedure → informed → adaptive (aim for informed+)

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.
