Use when a personal or team operating system needs a bounded redesign using Four-C, closed-loop controls, 70/30 allocation, 3B creativity, experiments, and prediction-error learning.

<skill_contract>
<input>One owned work system with its workflow, users, traces, permissions, metrics, constraints, and review horizon.</input>
<output>A supervised operating-system redesign with one bounded experiment, control gates, cadence, and rollback.</output>
<done>The selected practice has a baseline, hypothesis, owner, metric, guardrail, budget, stop rule, and review receipt.</done>
<non_goals>Extreme productivity claims, surveillance, automatic policy evolution, or cadence without supporting context and capability.</non_goals>
Redesign one work system as a supervised learning loop. Plasticity means practices may change from evidence; competition means alternatives contend; constraint means attention, time, permissions, and review bandwidth shape the design. Load references/operating-system-playbook.md for diagnostics and artifacts.
Provide: system boundary, owner, desired outcome, users, current workflow, local metrics, traces/data, permissions, failure history, review capacity, and horizon.
<intake>
Define one operating bottleneck and baseline. Run Four-C in order: Context (truth/history), Connections (systems/accounts), Capabilities (skills/SOPs/evals), Cadence (triggers/reviews). Do not add automation cadence until the first three can support and verify it.
</intake>
<unknowns_gate>
Treat productivity multipliers, culture narratives, maturity scores, and vendor case claims as hypotheses until local evidence exists. If outcome owner, trace consent, or approval authority is absent, return NEEDS_INPUT. Do not infer the expansion of local labels such as CASH when the system has not defined them.
</unknowns_gate>
<execute>
Use independent evaluation for organizational, cultural, or high-impact recommendations. A rollback restores the prior practice/config while retaining evidence and decision history.
</execute>
<evaluate>
Compare baseline and outcome on the named metric and guardrails. Inspect operator comprehension, review load, false positives, prediction calibration, and unintended incentives. Reject “success” when throughput rises but quality, agency, privacy, or local understanding falls.
</evaluate>
<retry_policy>
max_attempts: 2 per practice experiment. Retry only after changing the hypothesis, constraint, cohort, or mechanism. Stop on repeated signature, weak feedback, review overload, guardrail regression, or NO_PROGRESS.
</retry_policy>
<state_contract>
Persist {run_id, status, attempt, budget, evidence, unknowns, last_error, next_action} plus system boundary, Four-C audit, maturity evidence, flywheel/bottleneck, allocation, predictions, experiment version, metrics/guardrails, consent/approval, independent review, rollback point, and promotion decision.
</state_contract>
NEEDS_INPUT: owner, consent, outcome, or approval authority is missing.INSUFFICIENT_EVIDENCE: a maturity/policy claim lacks local observations.BLOCKED_PERMISSION: trace or delegated action exceeds authorized access.VERIFY_FAILED: outcome, guardrail, comprehension, or calibration check fails.NO_PROGRESS: changed experiments repeat the failure. max_attempts: 2.BUDGET_STOP: preserve the prior operating system and return a supervised next test.Return status, result (diagnosis, one redesigned loop, experiment, and review decision), evidence, unknowns, and next_action including approval or rollback.

Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
