Update threat intelligence through AgentSec

Scope: this guide repository and its AgentSec and landing consumers. This skill does not change global agent configuration. Its canonical source is .claude/skills/update-threat-db/; regenerate the Codex projection with python3 scripts/sync-threat-skill.py --write from the guide root.

Resolve the workflow

Read .claude/commands/update-threat-db.md from the guide root in full. It owns the delegation contract and consumer checks. Resolve AGENTSEC_REPO if set, otherwise the sibling ../agentsec-triage. Verify the required files before continuing. Do not silently substitute the guide's compatibility database.

Read the resolved AgentSec AGENTS.md and .claude/commands/update-threat-db.md in full, then execute that workflow. Preserve unrelated edits in all checkouts. Use the latest recorded update date through today's date as the research window.
