dataset-annotation

A tool for adding labels and shapes to images or video frames so they can train object-detection models. It can export the annotations in COCO format, a common dataset structure, and can upload datasets to Kaggle or Hugging Face.

In plain words
What is it for?
Draw or suggest bounding boxes, create pixel masks, find similar objects across frames, track objects through video, export COCO datasets, and upload them.
Why use it?
It reduces the manual work of marking every object in a training dataset while leaving a person to review and correct suggested annotations.

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

dataset-annotation 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/annotate.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Dataset Annotation

AI-assisted dataset creation for training custom detection models. Supports three annotation methods with COCO format export.

What You Get

  • BBox annotation — draw bounding boxes, AI auto-suggests
  • SAM2 annotation — click to segment, get pixel-perfect masks
  • DINOv3 annotation — click a patch, find similar objects across frames via visual grounding
  • Object tracking — annotate keyframes, DINOv3 interpolates across the video
  • COCO export — standard images[], annotations[], categories[] format
  • Kaggle/HuggingFace upload — push datasets directly to platforms

Annotation Loop

1. Feed frames from clips → auto-detect objects
2. Human reviews → corrects bboxes, adds labels
3. Save as COCO dataset
4. Train improved model
5. Repeat with better auto-detection

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

dataset-annotation is a skill published in the GitHub repository SharpAI/DeepCamera (3,031 stars, last pushed 2mo ago), licensed MIT. It adds 23 tokens to every session and 813 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 2026-08-30.
