by-scoring

by-scoring is a skill for Claude Code from 001TMF/blatant-why. It costs 3 tokens per session (10,441 once invoked), scanned A, original, MIT.

A scoring and interpretation skill for protein and antibody designs. It explains measures such as ipSAE, ipTM, pLDDT, RMSD, and liability scores, which estimate structure quality and possible design problems.

In plain words
What is it for?
Use it to rank designs, set quality cutoffs for different design types, investigate failed screening runs, compare metrics, and check whether results remain reliable across multiple random runs.
Why use it?
It helps turn several, sometimes conflicting, measurements into a consistent comparison of candidate designs.

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

by-scoring 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/calc_ipsae.py, scripts/composite_score.py, scripts/plot_score_distributions.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.

BY Scoring Skill

Interpret and apply BY custom scoring metrics for protein and antibody design. This skill covers ipSAE (interface Predicted Structural Accuracy Error) — the primary custom metric that differentiates BY from generic structure prediction tools — along with ipTM, pLDDT, RMSD, liability scoring, and the BY composite ranking formula.

ipSAE uses the open-source DunbrackLab formula (Dunbrack et al. 2025) with no proprietary dependencies. Use this skill whenever you need to score designs, interpret scoring output, troubleshoot disagreements between metrics, or advise on candidate ranking.


When to Use This Skill

Use this skill when:

  • ✅ Scoring designs after Protenix refolding — you have NPZ or confidence JSON output
  • ✅ Computing the BY composite score on a panel of screened designs
  • ✅ Explaining why two metrics (ipSAE vs ipTM) disagree on a candidate
  • ✅ Setting modality-specific thresholds (antibody vs nanobody vs de novo)
  • ✅ Diagnosing why an entire panel failed screening (zero LAB-READY)
  • ✅ Auditing whether a multi-seed result is stable or driven by one lucky seed
  • ✅ Interpreting asymmetric ipSAE (dt >> td or td >> dt)
  • ✅ Selecting the right PAE cutoff (10 A Protenix/AF3 vs 15 A AF2)

Don't use this skill for:

  • ❌ Generating designs — use the by-design-workflow skill instead
  • ❌ Running liability or developability screening directly — use the by-screening skill
  • ❌ Choosing which target to design against — use the by-research skill
  • ❌ Submitting candidates to a lab — use the by-lab agent (triple-gated)
  • ❌ Predicting raw structures — use the protenix skill

Quick Start

Compute ipSAE for a single Protenix output:

# JSON confidence file (Protenix /summary_confidence.json)
python scripts/calc_ipsae.py \
    --pae confidence.json \
    --chains confidence.json \
    --design A --target B \
    --pae-cutoff 10.0

# Or run the worked numerical example from references/
python scripts/calc_ipsae.py --example
# Expected: ipsae_min = 0.0396

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.

by-scoring is a skill published in the GitHub repository 001TMF/blatant-why (114 stars, last pushed 23d ago), licensed MIT. It adds 3 tokens to every session and 10,441 once invoked, about $0.0000 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.
