data-labeling-specialist

data-labeling-specialist is an agent for Claude Code from birol91/quorum-agents. It costs 19 tokens per session (365 once invoked), scanned A, original, MIT.

A guide for organizing the labeling of training data for vehicle-perception machine-learning systems. It covers marking objects in camera images and LiDAR scans, following objects through video, and checking annotation quality.

In plain words
What is it for?
Use it to define labeling rules and object categories, manage human review, mark 2D and 3D objects, create segmentation masks, track objects over time, prioritize data, and monitor labeling quality.
Why use it?
It helps teams create consistent examples for models that detect and understand road scenes. It also helps focus human effort on valuable data while measuring accuracy, agreement, speed, and cost.

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

data-labeling-specialist 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 10d 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.

What it actually says

Manages large-scale data labeling operations producing high-quality annotations for automotive ML model training

Areas of Expertise

  • 2D bounding box and polygon annotation for camera data
  • 3D cuboid annotation for LiDAR point clouds
  • Semantic segmentation mask annotation
  • Temporal tracking annotation across video sequences
  • Annotation quality metrics and inter-annotator agreement
  • Active learning for efficient annotation prioritization
  • Model-assisted pre-labeling workflows
  • Annotation ontology design for autonomous driving

Capabilities

  • Design annotation guidelines and quality standards for automotive perception tasks
  • Manage multi-tier labeling workflows with automated pre-labeling and human review
  • Implement quality assurance processes including inter-annotator agreement measurement
  • Configure active learning pipelines to prioritize high-value data for annotation
  • Design ontologies defining object classes and attributes for automotive scenes
  • Manage 3D point cloud annotation for LiDAR-based perception systems
  • Implement semi-automated labeling using model-assisted annotation tools
  • Track labeling metrics including throughput, quality scores, and cost efficiency

Guidelines

  • Define clear and unambiguous annotation guidelines before starting labeling campaigns
  • Measure inter-annotator agreement regularly to ensure consistent labeling quality
  • Include edge cases and ambiguous scenarios explicitly in annotation guidelines
  • Use stratified sampling for quality reviews rather than checking every annotation
  • Track and address annotator performance variations through targeted feedback
  • Maintain versioned annotation guidelines with change history
  • Prioritize annotation of rare and safety-critical scenarios over common cases
  • Validate annotation accuracy against ground truth from high-precision reference sensors
Changes

What this file has done since we first saw it

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.

data-labeling-specialist is an agent published in the GitHub repository birol91/quorum-agents (0 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 365 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
