SCOPE: $ARGUMENTS

If arguments are provided, use them to narrow the audit (e.g., a specific instrument integration, LIMS module, or compliance domain). If no arguments, scan the full project for lab automation infrastructure, instrument integrations, and data pipelines.

============================================================ PHASE 1: LABORATORY SYSTEM DISCOVERY

Step 1.1 -- Technology Stack Detection

Identify the lab automation platform:

• requirements.txt / pyproject.toml -> Python (SiLA 2, PyLabRobot, opentrons, Hamilton)
• pom.xml / build.gradle -> Java (LabVIEW integrations, custom LIMS)
• package.json -> Node.js (API gateways, dashboard layers)
• .cs / .csproj -> C# (.NET LIMS, instrument drivers)
• *.vi / *.lvproj -> LabVIEW (instrument control, data acquisition)
• Database schemas -> LIMS data model (samples, assays, results, batches)
• Docker/K8s configs -> Containerized instrument services, message brokers

Step 1.2 -- LIMS Architecture Mapping

Map the Laboratory Information Management System:

• Sample registration and accessioning workflows
• Assay/test definitions and method configurations
• Result entry, calculation engines, and approval chains
• Inventory management (reagents, consumables, standards)
• Certificate of Analysis (CoA) generation
• Integration layer (HL7, REST, SOAP, file-based, OPC-UA)
• Multi-site or multi-tenant configurations

Step 1.3 -- Instrument Landscape

Catalog connected instruments:

• Liquid handlers (Hamilton STAR, Beckman Biomek, Tecan, OpenTrons)
• Plate readers (BMG, Molecular Devices, BioTek)
• Mass spectrometers, chromatography (Agilent, Waters, Thermo)
• Sequencers (Illumina, PacBio, Oxford Nanopore)
• Robotic arms, incubators, centrifuges, barcode scanners
• Communication protocols: RS-232, USB, TCP/IP, OPC-UA, SiLA 2, REST
• Driver layer: vendor SDK, custom parsers, middleware (Thermo Fisher SampleManager, IDBS)

Step 1.4 -- Data Flow Architecture

Trace data from instrument to reporting:

• Raw data acquisition (file drops, streaming, API push)
• Parsing and normalization layers
• Database storage (relational, time-series, object storage)
• Calculation engines (derived results, curve fitting, statistics)
• Reporting and visualization (dashboards, PDF reports, SDTM export)
• Archive and retention policies

============================================================ PHASE 2: INSTRUMENT CONNECTIVITY ANALYSIS

Step 2.1 -- Integration Protocol Assessment

For each instrument integration, evaluate:

• Connection type (serial, USB, TCP/IP, cloud API)
• Protocol implementation (SiLA 2 compliance, OPC-UA, proprietary)
• Error handling: connection loss, timeout, retry logic, instrument faults
• Bidirectional communication: command dispatch and status polling
• Data format parsing: proprietary binary, CSV, XML, JSON, HDF5
• Throughput: can the integration handle peak sample volumes?

Step 2.2 -- Instrument Driver Quality

Assess driver implementations:

• Abstraction layer: is there a common interface across instrument types?
• Configuration management: instrument parameters, calibration settings
• State machine: proper modeling of instrument states (idle, running, error, maintenance)
• Concurrency: thread safety for multi-instrument orchestration
• Logging: structured logs with instrument ID, command, response, timestamps
• Testing: unit tests, integration tests, hardware-in-the-loop simulation

Step 2.3 -- Connectivity Resilience

Check robustness patterns:

• Automatic reconnection on connection drop
• Heartbeat/health check monitoring
• Graceful degradation when instruments are offline
• Queue management for command backlog during outages
• Alert escalation for persistent connectivity failures

============================================================ PHASE 3: SAMPLE TRACKING AND CHAIN OF CUSTODY

Step 3.1 -- Sample Lifecycle

Evaluate sample tracking from receipt to disposal:

• Unique sample identification (barcode, RFID, 2D matrix)
• Parent-child relationships (aliquots, derivatives, pooling)
• Location tracking (freezer, shelf, rack, position)
• Status transitions (received, in-process, complete, archived, disposed)
• Chain of custody audit trail (who, what, when, where)

Step 3.2 -- Barcode and Label Management

Assess labeling infrastructure:

• Barcode standards (1D Code 128, 2D DataMatrix per ANSI/SLAS)
• Label printing integration (Zebra, Brady, DYMO)
• Scanner integration at each workflow touchpoint
• Barcode validation (checksum verification, duplicate detection)
• Container-sample association integrity

Step 3.3 -- Storage and Logistics

Check sample storage management:

• Freezer/refrigerator mapping with position-level tracking
• Temperature monitoring and excursion alerting
• Capacity planning and optimization
• Sample retrieval workflows (pick lists, location guidance)
• Shipping and receiving (manifest generation, chain of custody)

============================================================ PHASE 4: PROTOCOL AUTOMATION AND WORKFLOW ENGINE

Step 4.1 -- Workflow Definition

Evaluate protocol automation:

• Workflow engine type (state machine, DAG, BPM, custom)
• Protocol definition format (JSON, YAML, visual designer, code)
• Step types: manual, automated, conditional, parallel, approval gates
• Parameter management: protocol templates vs. instance overrides
• Version control for protocol definitions

Step 4.2 -- Execution Engine

Assess runtime behavior:

• Task scheduling and prioritization (FIFO, priority queue, SLA-based)
• Resource allocation (instruments, operators, reagents)
• Parallelization: concurrent sample processing across instruments
• Error recovery: retry policies, skip-and-flag, manual intervention
• Real-time progress tracking and ETA estimation

Step 4.3 -- Automation Orchestration

Check multi-instrument coordination:

• Workcell integration (plate movements between instruments)
• Scheduling optimization (minimize idle time, reduce plate wait)
• Dead volume and tip management
• Plate mapping and well-level tracking
• Robotic arm path planning and collision avoidance

============================================================ PHASE 5: DATA PIPELINE AND INTEGRITY

Step 5.1 -- Data Acquisition Pipeline

Evaluate data ingestion:

• File watchers, streaming consumers, API endpoints
• Format validation and schema enforcement
• Duplicate detection and idempotent processing
• Transformation logic (unit conversion, normalization, outlier flagging)
• Pipeline monitoring (lag, throughput, error rates)

Step 5.2 -- Calculation Engine

Assess scientific calculations:

• Curve fitting (4PL, 5PL, linear regression, Michaelis-Menten)
• Statistical analysis (mean, CV, standard deviation, Grubbs test)
• Acceptance criteria enforcement (specification limits, system suitability)
• Audit trail for calculation parameters and formula versions
• Validation documentation for calculation methods

Step 5.3 -- 21 CFR Part 11 Compliance

Audit electronic records and signatures:

• Electronic signatures: meaning, linking to record, non-repudiation
• Audit trails: creation, modification, deletion with timestamp and user ID
• Access controls: role-based, least privilege, separation of duties
• Data integrity: ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate)
• System validation: IQ/OQ/PQ documentation per GAMP 5 categories
• Backup and recovery: validated restore procedures
• Closed system controls or open system security measures

Step 5.4 -- GAMP 5 Classification

Verify software categorization:

• Category 1: Infrastructure software (OS, database, network)
• Category 3: Non-configured products (firmware, embedded)
• Category 4: Configured products (LIMS, COTS with configuration)
• Category 5: Custom applications (bespoke lab software)
• Verify appropriate validation rigor matches category
• Check for risk-based approach to validation activities
• Verify traceability matrix (requirements -> tests -> results)

============================================================ PHASE 6: WRITE REPORT

Write analysis to docs/lab-automation-analysis.md (create docs/ if needed).

Include: Executive Summary, System Architecture Diagram (text-based), Instrument Inventory with connectivity status, Sample Tracking Assessment, Protocol Automation Maturity, Data Pipeline Integrity, 21 CFR Part 11 Compliance Gaps, GAMP 5 Classification Review, Prioritized Remediation Plan.

============================================================ 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 /research-data-management to assess FAIR data principles and metadata governance."
• "Run /experiment-tracking to evaluate reproducibility and experiment versioning."
• "Run /pharma-compliance to audit broader GxP compliance across the organization."

DO NOT:

• Do NOT modify any instrument drivers, LIMS configurations, or production workflows.
• Do NOT execute any instrument commands or trigger automated protocols.
• Do NOT access or display patient/subject identifiable data from sample records.
• Do NOT skip 21 CFR Part 11 assessment even for research-use-only systems.
• Do NOT assume GAMP 5 category without verifying the actual software configuration.

============================================================ 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:

### /lab-automation — {{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.
