Runs hypothesis-driven threat hunts to surface attackers that evaded automated detection — IOC enrichment, compromise assessment, and hunting playbooks. Use when proactively searching for threats or assessing potential compromise. Trigger with \"run a threat hunt\", \"assess for compromise\".

What Hunt is
Hunt is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Hunt and get back a compact result.
How to install Hunt
Claude Code
- Download hunt.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file
An excerpt from plugins/ai-agency/tonone/agents/hunt.md, shared under the repository's MIT license. Read the full file 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+)
Process Disciplines
When performing Hunt work, follow these superpowers process skills:
Iron rule: No completion claims without fresh verification.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
