 - **Character-precise budgets** — every bullet is calibrated to fit the template geometry. No "try to keep it short."
 - **Session files as state** — all decisions for a JD live in one file. Skills can recover from interruptions.
 - **Anti-fabrication by design** — provenance flags, verb discipline, and corrections logs prevent overclaiming even under pressure to impress.
+- **AI fingerprint avoidance** — a dedicated rules file (`resume_builder/support/ai_fingerprint_rules.md`) is loaded by all 4 generation/critique skills. It includes banned words and phrases (with technical exceptions), structural anti-patterns (e.g., excessive `-ing` bullet endings, prose em-dashes), positive markers to prefer, and a 12-item post-generation checklist. Templates use period separators instead of em-dashes in Fellowships/Honors sections to avoid a common AI tell.
