TARGET: $ARGUMENTS

If arguments are provided, focus on that area (e.g., "screening workflows", "ADMET models", "IND readiness"). If no arguments, scan the full codebase for drug discovery infrastructure, screening workflows, and pipeline management.

============================================================ PHASE 1: DISCOVERY PLATFORM INVENTORY

Step 1.1 -- Technology Stack Detection

Identify platforms from package manifests and config files:

• requirements.txt with rdkit, deepchem, schrodinger -> cheminformatics / computational chemistry.
• pom.xml / .jar files -> Java-based platforms (IDBS, Dotmatics, CDD Vault).
• Database schemas with compound/assay tables -> screening data management.
• *.sdf, *.mol2, *.pdb, *.smi -> chemical structure files.
• *.fasta, *.pdb -> bioinformatics / structural biology.
• Jupyter notebooks with molecular modeling -> computational pipeline.
• Configuration for Schrodinger, OpenEye, MOE, ChemAxon -> modeling tools.
• REST/GraphQL APIs -> registration systems, ELN integration.

Step 1.2 -- Compound Library Assessment

Catalog compound management capabilities:

• Compound registration system: unique IDs, structure normalization, salt stripping.
• Library composition: diversity library, focused library, fragment library, natural products.
• Library size and chemical space coverage.
• Storage and logistics: plate management, cherry-picking, reformatting.

============================================================ PHASE 2: SCREENING WORKFLOW ANALYSIS

Step 2.1 -- High-Throughput Screening (HTS)

Evaluate HTS infrastructure quality:

• Assay format: biochemical, cell-based, phenotypic, fragment-based.
• Screening cascade design: primary, confirmatory, dose-response, selectivity.

• Selectivity panel: off-target pharmacology, kinase selectivity.
• In vivo PK studies: exposure, bioavailability, distribution.
• Efficacy models: disease-relevant in vivo or ex vivo models.
• Data integration across profiling endpoints.

============================================================ PHASE 4: ADMET PREDICTION AND MODELING

Step 4.1 -- ADMET Model Inventory

Catalog all predictive models and verify coverage:

• Absorption: Caco-2 permeability, PAMPA, oral bioavailability prediction.
• Distribution: plasma protein binding, volume of distribution, BBB penetration.
• Metabolism: CYP substrate/inhibitor prediction, metabolic stability, metabolite ID.

Step 4.2 -- Model Quality Assessment

Critically evaluate ADMET model performance:

• Validation methodology: temporal split, scaffold split, random split.
• Performance metrics: R-squared, RMSE, accuracy, AUC for classification.
• Applicability domain definition and out-of-domain flagging.
• Model update frequency and retraining triggers.
• Predicted vs. measured concordance on recent compounds.

Step 4.3 -- Integration and Decision Support

Assess how models feed into decisions:

• ADMET predictions integrated into compound selection workflows.
• Multi-objective scoring: balancing potency, selectivity, ADMET.
• Visualization of ADMET profiles: radar charts, traffic-light scoring.
• Alerts for liability flags: hERG above threshold, CYP inhibition, reactive metabolites.
• Confidence scoring on predictions.

============================================================ PHASE 5: CLINICAL CANDIDATE SELECTION

Step 5.1 -- Candidate Selection Criteria

Evaluate selection framework quality:

• Target product profile (TPP) documentation and compliance checking.
• Go/no-go criteria at each stage gate.
• Candidate selection package requirements: potency, selectivity, PK, safety.

• Stability study planning.

Step 5.3 -- Regulatory Strategy

Evaluate IND preparation:

• FDA Pre-IND meeting preparation.
• IND application component tracking: CMC, pharmacology/toxicology, clinical.
• Regulatory pathway assessment: 505(b)(1), 505(b)(2), biosimilar.
• Orphan drug or breakthrough therapy designation evaluation.
• Timeline and milestone tracking to IND filing.

============================================================ PHASE 6: OPERATIONAL METRICS AND GOVERNANCE

Step 6.1 -- Pipeline Metrics

Assess operational KPIs:

• DMTA cycle time: days from design to data.
• Screening throughput: compounds per week.
• Hit rate and confirmation rate by target class.
• Lead optimization progress: number of cycles, MPO improvement.
• Stage gate transition rates and timelines.
• Cost per stage: hit finding, lead optimization, candidate selection.

Step 6.2 -- Data Governance

Evaluate data integrity:

• Compound registration integrity: no duplicates, correct structures.
• Assay data quality controls and review workflows.
• Electronic lab notebook compliance.
• Data archival and long-term accessibility.
• IP documentation and invention disclosure tracking.

============================================================ PHASE 7: WRITE REPORT

Write analysis to docs/drug-discovery-ops-analysis.md (create docs/ if needed).

Include: Executive Summary, Platform Inventory, Screening Workflow Assessment, Hit-to-Lead Pipeline Review, ADMET Model Evaluation, Candidate Selection Readiness, Operational Metrics Dashboard, Governance Assessment, Prioritized Recommendations.

============================================================ SELF-HEALING VALIDATION (max 2 iterations)

After producing output, validate data quality and completeness:

1. Verify all output sections have substantive content (not just headers).
2. Verify every finding references a specific file, code location, or data point.
3. Verify recommendations are actionable and evidence-based.
4. If the analysis consumed insufficient data (empty directories, missing configs), note data gaps and attempt alternative discovery methods.

IF VALIDATION FAILS:

• Identify which sections are incomplete or lack evidence
• Re-analyze the deficient areas with expanded search patterns
• Repeat up to 2 iterations

IF STILL INCOMPLETE after 2 iterations:

• Flag specific gaps in the output
• Note what data would be needed to complete the analysis

NEXT STEPS:

• "Run /regulatory-submissions to assess eCTD assembly and FDA submission readiness."
• "Run /lab-automation to evaluate screening instrument automation and LIMS integration."
• "Run /experiment-tracking to assess compound profiling data reproducibility."

DO NOT:

• Do NOT modify any compound records, assay data, or pipeline configurations.
• Do NOT access or display proprietary chemical structures outside the analysis report.
• Do NOT make clinical efficacy or safety predictions -- flag data for expert review.
• Do NOT skip GLP compliance assessment even for early-stage discovery programs.
• Do NOT assume ADMET model accuracy without checking applicability domain and validation metrics.

============================================================ SELF-EVOLUTION TELEMETRY

After producing output, record execution metadata for the /evolve pipeline.

Check if a project memory directory exists:

• Look for the project path in ~/.claude/projects/
• If found, append to skill-telemetry.md in that memory directory

Entry format:

### /drug-discovery-ops — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}

Only log if the memory directory exists. Skip silently if not found. Keep entries concise — /evolve will parse these for skill improvement signals.
