huntkit

Investigation toolkit for Claude Code. Case management, OSINT, structured analytic techniques, chain-of-custody evidence capture, and bundled MCP servers for infrastructure recon and threat intel.

Not just a scraper wrapper. A full investigation workflow — from case intake to evidence-grade dossier.

Use it for: OSINT, due diligence, threat intelligence, incident response, digital forensics, journalistic research, competitive intel, security research, CTF challenges.

What you get

Skills

• osint — 6-phase investigation: tooling check → seed collection → optional internal intel → platform extraction → cross-reference → psychoprofile → completeness scoring → dossier.
• structured-analysis — CIA tradecraft primer library (Heuer's ACH, key assumptions check, quality of information check, red team, premortem, 66-technique taxonomy). Apache 2.0, upstream Blevene/structured-analysis-skill.

Commands (22)

Case management: /q-new-case, /q-scope, /q-begin, /q-status, /q-checkpoint, /q-handoff, /q-end

Collection: /q-intake, /q-collect, /q-osint, /q-target, /q-screenshots

Analysis: /q-analyze, /q-challenge, /q-reality-check, /q-client-questions, /q-timeline, /q-link

Reporting: /q-brief, /q-debrief, /q-export

Specialized: /q-sec-stack (SaaS security stack intel)

MCP servers (bundled)

• osint-infra — WHOIS, DNS, reverse DNS, Wayback snapshots / fetch.
• threat-intel — VirusTotal, URLhaus, ThreatFox, crt.sh certificate transparency.

Rules (enforced)

• evidence-capture-protocol — every URL routes through capture-evidence.sh (Wayback + archive.today + Chrome PDF + SHA-256 + metadata). Atomic EV-NNNN-<slug>/ folders. Reports cite by ID.
• q-investigation — fail-stop on errors, token discipline, state-vs-session file authority, source reliability A-F scale.
• token-discipline — stop conditions, retry limits.
• sycophancy — anti-RLHF drift, decision origin tagging.

Templates

• new-investigation/ — full case scaffold (canonical/, investigation/evidence|findings|targets|timelines/, memory/, output/).
• sec-stack-case/ — SaaS security stack investigation template.

Typical workflow

/q-new-case acme-breach
/q-scope          # define question, targets, constraints
/q-begin          # resume session
/q-intake <file>  # ingest client-provided docs
/q-osint linkedin https://linkedin.com/in/someone
/q-collect domain acme.com
/q-target acme-ceo
/q-timeline       # reconstruct event sequence
/q-analyze ach    # analysis of competing hypotheses
/q-challenge      # red team own conclusions
/q-brief          # generate evidence-grounded report
/q-export         # final package

Every URL captured routes through the evidence protocol. Every report cites [EV-NNNN]. Every claim has an A-F reliability grade.

Provenance & sync

huntkit is built from a live investigation practice. The commands, skills, and rules here are the same files running real cases daily, synced automatically on every upstream change through a build script that anonymizes case references and gates the publish behind a client-indicator blocklist plus a gitleaks secret scan. Case-specific tooling and client data never leave the source repo.

Enforcement hooks ship wired since v0.3.0 (hooks/hooks.json): a token-bleed circuit breaker (PreToolUse) and a findings-attribution gate that blocks a CONFIRMED/HIGH-CONFIDENCE finding citing an identifier still marked UNVERIFIED (PostToolUse). Installing the plugin activates both; no manual settings edits.

Contributing

Issues and PRs welcome. Backward-compatible additions preferred. Note that synced paths (commands/, skills/, rules/, .q-system/, mcp-servers/) are overwritten by the upstream sync; PRs against them are best raised as issues so the change lands upstream first.
