OSINT investigation agents — domain and infrastructure intel, and people/entity investigation with mandatory ethical authorisation gates.
Investigator — people-focused investigation using public records and open sources. Identity verification, background research, social media footprint, corporate beneficial ownership. Use when you need to verify a person's identity, research their public background, or map corporate ownership structures. Mandatory ethical gate runs before every investigation.
OSINT analyst — technical investigation of domains, IP infrastructure, and organisational digital footprints using public registries and open sources. Use when mapping a domain's infrastructure, investigating an IP address, or building an entity's digital footprint. Does NOT investigate private individuals.
Map a company's ownership chain, related entities, and director networks. Use for beneficial ownership investigation, M&A research, or understanding complex corporate structures. Full AU/NZ/UK/US registry coverage.
Investigate a domain's registration, DNS, certificates, hosting, and history using passive public sources. Use when mapping a domain's infrastructure or researching who owns/operates it.
Map an organisation's complete public digital presence: domains, web presence, social profiles, apps, code repositories, job postings, and regulatory filings.
Verify that a named individual is who they claim to be, or resolve ambiguity between people sharing a name. Anchors on verifiable claims and cross-references independently. Requires authorisation gate.
Investigate an IP address: ownership, hosting provider, ASN, reputation, and associated infrastructure. Passive sources only — no active scanning.

A plugin marketplace for Claude Code. Agents, skills, rules, and conventions that work together as a virtual team.
/plugin marketplace add hpsgd/turtlestack
Start with the core plugins (rules, thinking skills, and code review), then add agents for your stack:
/plugin install coding-standards@hpsgd
/plugin install writing-style@hpsgd
/plugin install security-compliance@hpsgd
/plugin install thinking@hpsgd
/plugin install tooling@hpsgd
/plugin install code-reviewer@hpsgd
/plugin install ai-engineer@hpsgd
Add a technology stack if relevant:
/plugin install dotnet-stack@hpsgd
/plugin install nextjs-stack@hpsgd
/plugin install python-stack@hpsgd
Then reload:
/reload-plugins
Browse the full plugin list below to see what else is available.
Per-project overrides. Create your own .claude/rules/ files. Project-level rules take precedence over marketplace rules.
Disabling a plugin. Set it to false in .claude/settings.json:
{
"enabledPlugins": {
"writing-style@hpsgd": false
}
}
Local overrides (not committed). Use .claude/settings.local.json for personal preferences that shouldn't affect the team.
