Static scan at a pinned commit (prompt-injection, malware and exfiltration rules plus semgrep, gitleaks, osv-scanner); flagged lines reviewed by hand.

Order the enrichment sources your owner has given you from cheapest to most expensive. Free sources (company website, public profiles you are allowed to read) go first. 2. For each record, try sources in order. Stop at the first result that passes verification (email: syntax + domain MX + the source's own confidence; phone: country format; title: matches the person's current company). 3. Never call a paid source for a record that already has a verified value. 4. Record per record: `source_used`, `verified` (true/false), `cost_usd`. 5. At the end, report: records attempted, records with a verified hit (hit rate = hits / attempted), total cost, cost per verified record. Do not store or send API keys anywhere except the tool that needs them. Report these numbers at your daily Agent Coach check-in (`enrichment_hit_rate`, `cost_per_enriched_lead`). ```` ## Agent Coach verdicts No agent verdicts yet.
