Conciseness

Mostly efficient tables and terse directives, but redundancy exists: the note "(requires NVIDIA_API_KEY env var; free key at build.nvidia.com)" is repeated five times in the tools table and again in the NVIDIA NIM Requirements section, and the Common Parameter Mistakes table partially repeats the key parameters already given. Not score 5 because not every token earns its place; well above score 3's noticeable padding.

Actionability

Concrete guidance throughout — exact tool names, required parameters ("contigs + input_pdb (both required), diffusion_steps (NOT num_steps...)"), sampling thresholds, and tier cutoffs ("pLDDT >85, pTM >0.8") — but no executable example invocations in the body; the code examples are delegated to DESIGN_PROCEDURES.md, which is not in the bundle. Fits 'mostly executable with minor gaps' rather than fully copy-paste ready.

Workflow Clarity

The 6-phase workflow is clearly sequenced with validation checkpoints (filter backbones by geometry, pLDDT/pTM thresholds, '>= 3 passing') and a completeness checklist, but the error-recovery feedback loop (what to do when validation fails, e.g., regenerate backbone or resample at different temperature) is only implied and delegated to a reference file. Score 4 rather than 5 because feedback loops are not explicit in the body.

Progressive Disclosure

The Reference Files section is well-signaled with one-line descriptions and would be one level deep, but none of the five referenced files (DESIGN_PROCEDURES.md, TOOLS_REFERENCE.md, EXAMPLES.md, CHECKLIST.md, design_templates.md) exist in the bundle — no references/, scripts/, or assets/ directories are present — so the disclosure paths are dangling and the detail content they promise is unavailable. Structure is better than score 2, but broken references keep it below score 4.

Specificity

Lists multiple concrete pipeline actions with named tools and metrics — "RFdiffusion backbone generation, ProteinMPNN sequence design, structure validation (pLDDT, pTM, MPNN scores)" — covering the full design workflow comprehensively, matching the anchor for multiple specific concrete actions rather than the score-4 anchor with minor gaps.

Completeness

Explicitly answers both: what ("RFdiffusion backbone generation, ProteinMPNN sequence design, structure validation") and when ("Use for designing therapeutic protein binders, novel scaffolds, enzyme variants, and miniprotein/protein-interface design before experimental validation"), with concrete trigger phrases exactly as the score-5 anchor requires.

Trigger Term Quality

Good natural-term coverage ("protein design", "therapeutic protein binders", "novel scaffolds", "enzyme variants", "protein-interface design") but misses common synonyms a user might say such as "protein engineering", "antibody/nanobody", or "peptide design". Not score 5 since synonyms are not comprehensively covered; clearly above score 3's partial coverage.

Distinctiveness Conflict Risk

Clear niche (de novo therapeutic protein design) with named tools (RFdiffusion, ProteinMPNN) and distinct design-oriented triggers; minimal overlap with general structure-prediction or campaign-management skills since the 'Use for' clause scopes it to design tasks specifically.
