pylabrobot
Laboratory automation toolkit for controlling liquid handlers, plate readers, pumps, heater shakers, incubators, centrifuges, and analytical equipment. Use this skill when automating laboratory workflows, programming liquid handling robots (Hamilton STAR, Opentrons OT-2, Tecan EVO), integrating lab equipment, managing deck layouts and resources (plates, tips, containers), reading plates, or creating reproducible laboratory protocols. Applicable for both simulated protocols and physical hardware control.
ab-test-analysis
Design and analyze A/B tests, calculate statistical significance, and determine sample sizes for conversion optimization and experiment validation
domain-healthcaremedical-device-software
Medical device software development covering IEC 62304 software lifecycle, ISO 14971 risk management, design controls, software verification and validation, FDA regulatory submissions, software change control, and cybersecurity for medical devices.
archive-experiment
Archive a completed experiment, preserving all experiment files while deleting bulk checkpoint artifacts. Use after summarize-experiment or analyze-experiment when an experiment is complete and results have been reviewed.
fix-test-failures
This skill should be used after running tests when failures occur. It ensures test failures are properly diagnosed through instrumentation and logging until the root cause is found and fixed. The skill treats all test failures as real bugs that must be resolved, never skipped.
data-analysis-patterns
Best practices for data aggregation, recalculation, and category management in scientific analyses. Covers when to recalculate vs reuse aggregated data, handling category changes, and ensuring analytical accuracy.
metrics-analytics
Product analytics: AARRR framework, North Star Metric, A/B testing with statistical significance (95% confidence, minimum detectable effect), PostHog event tracking, funnel analysis, retention cohorts, feature flags for experiments. Vanity metrics vs actionable metrics. Use when defining KPIs, designing experiments, interpreting data.
worktree-sparsity-eval
Evaluate repository size metrics to determine whether worktrees should use sparse checkout. Invoke when starting work in an unfamiliar repository, before creating the first worktree in a repo where no sparsity metrics exist in CLAUDE.md, or for periodic re-evaluation when a repo has grown significantly.
experiment-structure
Standard experiment folder structure and templates. Reference for creating or validating experiment folders.
colibri-audit-memory
Bridge audit trails and memory frames for comprehensive session recording. Greek: ζ (zeta) — Decision Trail, η (eta) — Proof Store. Use when recording audit sessions, creating memory bundles, linking audit trails to memory, or finalizing session proofs with memory archives.
ams-observability
Redirect stub → use colibri-observability. Observability + proof — memory management, Merkle proof trees, audit sessions, system health. Load .claude/skills/colibri-observability/SKILL.md for full content.
colibri-audit-memory
Bridge audit trails and memory frames for comprehensive session recording. Greek: ζ (zeta) — Decision Trail, η (eta) — Proof Store. Use when recording audit sessions, creating memory bundles, linking audit trails to memory, or finalizing session proofs with memory archives.
medical-device-distribution

Also use when the user mentions "medical device logistics," "UDI compliance," "device traceability," "consignment management," "implant tracking," "loaner sets," "FDA compliance," "sterile device distribution," "recall management," or "GS1 standards." For hospital internal logistics, see hospital-logistics. For pharmaceutical distribution, see pharmacy-supply-chain.
clinical-trial-logistics
When the user wants to optimize clinical trial supply chain, manage investigational products, implement IRT systems, or ensure GCP compliance. Also use when the user mentions "clinical trial supply," "IMP logistics," "IVRS/IWRS," "drug accountability," "randomization and supply," "comparator sourcing," "depot management," "clinical packaging," "site resupply," or "GCP compliance." For pharmacy operations, see pharmacy-supply-chain. For general healthcare logistics, see hospital-logistics.
cycle-counting
When the user wants to implement or optimize cycle counting programs, improve inventory accuracy, or design physical inventory processes. Also use when the user mentions "inventory accuracy," "physical inventory," "stock counting," "ABC cycle counting," "perpetual inventory," "inventory reconciliation," or "variance analysis." For inventory optimization, see inventory-optimization. For warehouse operations, see warehouse-design.
nucleus-apple-health
Query and analyze exported Apple Health metrics and raw samples with the `nucleus-apple` CLI. Use when the task involves trend summaries, daily metrics, raw sample inspection, sync change history, or diagnosing gaps between aggregates and raw exports.
