phenix-tools-reference

phenix-tools-reference is a skill for Claude Code, Codex from openscientist-io/openscientist. It costs 15 tokens per session (2,238 once invoked), scanned A, original, Apache-2.0.

A reference guide to Phenix commands, a software toolkit used to analyze and refine three-dimensional protein structures.

In plain words
What is it for?
Use it to select Phenix tools for validation, steric-clash and backbone checks, model-to-data comparison, structural superposition, refinement, and map analysis.
Why use it?
It helps choose the right command for checking structure quality, comparing models, refining them, or analyzing experimental maps.

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

phenix-tools-reference 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phenix Tools Reference

If Phenix is available, prefer run_phenix_tool over execute_code for structural biology tasks like validation, superposition, refinement, and map analysis. Phenix is the gold standard for these tasks.

Call run_phenix_tool(tool_name="phenix.<command>", input_files=["file.pdb"], description="..."). This reference lists the most useful commands grouped by task. Most commands accept PDB or mmCIF files, but some take map files, reflection data, sequences, or other formats — check each tool's --help if you are unsure.

Validation and Quality Assessment

Command Purpose
phenix.molprobity Comprehensive validation: Ramachandran, rotamers, clashes, C-beta deviations; the single best overall quality check
phenix.clashscore All-atom steric clash analysis
phenix.ramalyze Ramachandran backbone analysis
phenix.rotalyze Side-chain rotamer analysis
phenix.cablam C-alpha based backbone validation
phenix.cbetadev C-beta deviation analysis
phenix.omegalyze Cis/trans peptide bond validation
phenix.model_vs_data Model versus diffraction data statistics
phenix.model_statistics Summary geometry statistics for a model
phenix.emringer Map-model validation for cryo-EM structures
phenix.validation_cryoem Comprehensive cryo-EM validation
phenix.undowser_validation Check waters for clashes and poor contacts
phenix.clashscore2 Updated all-atom clash score (prefer over clashscore when available; slightly different scoring)
phenix.undowser2_validation Updated water validation (same relationship to undowser_validation as above)
phenix.holton_geometry_validation Holton-method geometry validation — complementary signal to molprobity; useful for second-opinion checks

Example: Full validation

run_phenix_tool(
    tool_name="phenix.molprobity",
    input_files=["structure.pdb"],
    description="Comprehensive structure quality check",
)

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.
