face-recognition

face-recognition is a skill for Claude Code from liortesta/ClawdAgent. It costs 0 tokens per session (790 once invoked), scanned A, original, Apache-2.0.

A face-recognition software development kit for security and access-control work. It can locate faces, verify or identify people, check whether a face is live, assess image quality, and process several faces at once.

In plain words
What is it for?
Use it to audit access-control systems, test identity verification, check enrollment images, and evaluate anti-spoofing and demographic-analysis workflows.
Why use it?
It helps developers test whether biometric systems correctly recognize authorized people and resist simple spoofing attempts such as photos or video replays.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

face-recognition scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Face Recognition Security — FacePlugin

For authorized security testing and access control auditing only.

Overview

FacePlugin is a face recognition SDK used in security contexts for access control systems, identity verification auditing, and biometric security assessments. Understanding face recognition technology is critical for auditing biometric authentication systems.

Core Capabilities

  • Face Detection: Locate faces in images/video with bounding boxes
  • Face Recognition: 1:1 verification (is this person who they claim?) and 1:N identification (who is this person?)
  • Liveness Detection: Anti-spoofing checks (photo attack, video replay, 3D mask detection)
  • Age/Gender Estimation: Demographic analysis for access control policies
  • Face Quality Assessment: Image quality checks for enrollment suitability
  • Multi-Face Processing: Detect and process multiple faces in a single frame

Key Security Concerns in Face Recognition Systems

  1. Presentation Attacks: Spoofing with photos, videos, masks, or deepfakes
  2. Template Theft: Extracting stored face templates from database
  3. Adversarial Attacks: Subtle perturbations that fool the system
  4. Bias Testing: Ensure equal accuracy across demographics (skin tone, age, gender)
  5. Privacy Compliance: GDPR/CCPA compliance for biometric data storage
  6. API Security: Authentication and rate limiting on face recognition endpoints
  7. Data Minimization: Ensure only necessary biometric data is stored

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

face-recognition is a skill published in the GitHub repository liortesta/ClawdAgent (11 stars, last pushed 14d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 790 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
