What is SetOptics AGENTS.md?

Repository-specific instructions for SetOptics, an open-source project that detects volleyball rallies in video. They explain the project layout, approved entry points, and working rules for coding agents.

Working on SetOptics detection pipelines, annotation tools, scripts, and rally or segment evaluation tasks.

They give an agent the local context needed to change or run the project without guessing where code belongs or which evaluation tools to use.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01241	$0.01241
Opus 5.5	$0.00496	$0.00496
Sonnet 5.5	$0.00248	$0.00248

Security

Grade A, and why

SetOptics AGENTS.md 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 1mo 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 this repo is

Open-source rally-detection pipelines for volleyball video. Library + scripts, no service layer. The detection modes are: signal, videomae, ensemble, llm (Gemini).

Where the code lives

setoptics/ is the importable Python package (ball tracker, Gemini pipeline, prompts, base classes).
scripts/ holds standalone CLI entry points. They are research-grade but functional. Each one is its own __main__ and uses argparse.
tools/annotation/ holds the ground-truth labeling pipeline. It is importable and runnable.
tools/shared/eval/temporal.py is the canonical evaluation framework. Use it for any new rally/segment metric work; do not write parallel metric code.

Working rules for agents

Read README.md first. It is the source of truth for what each mode does and how to invoke it.
Use the canonical entry points. Detection runs through scripts/*_rally_detector.py. Annotation runs through tools/annotation/annotate_sliding_window.py (high quality) or annotate_fast.py (fast iteration). Do not invent new wrappers.
Activate the venv before running Python. All scripts assume the project venv is active (source .venv/bin/activate).
Do not commit user data. data/ and any *_annotations*.json files are gitignored. Do not stage them.
One file = one purpose. Hard cap of 500 lines per code file. If a change pushes over this, split.
No new directories without reason. The layout is fixed; new modules go in setoptics/, new CLIs in scripts/, new annotation tools in tools/annotation/.
Apache 2.0. All new files inherit the repo license. Do not add conflicting license headers.

Common tasks

Run rally detection on a video

python scripts/signal_rally_detector.py --video FOOTAGE.mp4 --output OUT.json
python scripts/ensemble_rally_detector.py --video FOOTAGE.mp4 --output OUT.json --mode fast
python tools/annotation/annotate_sliding_window.py FOOTAGE.mp4   # LLM path

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.
