crispr-screen-analyzer

Process CRISPR screening data to identify essential genes and hit candidates. Performs quality control, log fold change calculation, z-score-based sgRNA scoring, and hit calling for pooled CRISPR screens including viability, drug resistance, and synthetic lethality studies.

Quality

Discovery

82%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong, technically specific description that clearly defines the domain (CRISPR screening) and lists concrete analytical capabilities. The main weakness is the absence of an explicit 'Use when...' clause, which would help Claude know exactly when to select this skill. The domain-specific terminology provides excellent distinctiveness.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user mentions CRISPR screens, sgRNA analysis, gene essentiality, or pooled screening data.'

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'quality control, log fold change calculation, z-score-based sgRNA scoring, and hit calling' along with specific study types (viability, drug resistance, synthetic lethality).

3 / 3

Completeness

Clearly answers 'what does this do' with detailed capabilities, but lacks an explicit 'Use when...' clause or equivalent trigger guidance. The when is only implied through the domain context.

2 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'CRISPR screening', 'essential genes', 'hit candidates', 'sgRNA', 'pooled CRISPR screens', 'viability', 'drug resistance', 'synthetic lethality' - comprehensive coverage of domain terminology.

3 / 3

Distinctiveness Conflict Risk

Highly specialized niche with distinct triggers like 'CRISPR screening', 'sgRNA scoring', 'pooled CRISPR screens' - very unlikely to conflict with other skills due to the specific scientific domain.

Implementation

64%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill provides strong actionable guidance with executable commands, clear parameter documentation, and specific QC thresholds. However, the workflow section is generic rather than domain-specific, and there's notable redundancy between output-related sections. The skill would benefit from a more explicit analytical workflow with validation checkpoints between QC, normalization, and hit-calling steps.

Suggestions

Replace the generic 5-step workflow with a CRISPR-specific analytical sequence: (1) Load and validate inputs → (2) Run QC checks → (3) If QC passes, calculate LFC → (4) Score sgRNAs → (5) Call hits with FDR correction, with explicit validation gates between steps.

Consolidate 'Output Requirements', 'Response Template', and 'Stress-Case Output Structure' into a single section to reduce redundancy.

Add a validation checkpoint after QC assessment that explicitly gates whether to proceed with differential analysis (e.g., 'If Gini > 0.3 or correlation < 0.7, stop and report QC failure before LFC calculation').

DimensionReasoningScore

Conciseness

The skill contains useful information but includes some redundancy (e.g., the 'Output Requirements' and 'Response Template' sections overlap significantly, and the 'Stress-Case Output Structure' duplicates guidance). The workflow section is generic and could be tightened.

2 / 3

Actionability

Provides fully executable commands with concrete examples, clear parameter tables with types and defaults, specific QC thresholds with action items, and copy-paste ready usage examples for both QC-only and full analysis modes.

3 / 3

Workflow Clarity

The workflow section is too abstract and generic (not specific to CRISPR analysis). While there's a good fallback template and error handling section, the actual analytical workflow (QC → LFC → scoring → hit calling) is not explicitly sequenced with validation checkpoints between steps.

2 / 3

Progressive Disclosure

Content is reasonably organized with clear sections and tables, but everything is inline in one file. References to upstream/downstream tools are mentioned but not linked. Some sections (Output Requirements, Response Template, Stress-Case Output Structure) could be consolidated or moved to a separate reference file.
