Apply thermodynamic reasoning — entropy, free energy, reversibility — to codebase decay, tech debt, drift, and the cost of maintenance.

Skill Claude Code
Reason about absolute and relative error, floating-point precision, condition numbers, and accumulated error in iterative methods, money, timestamps, geo, and ML pipelines.

Skill Claude Code
Apply natural selection thinking to API and codebase evolution — what is being selected for, what drifts, what persists vestigially, and where the system sits on its fitness landscape.

Skill Claude Code
Designed margin against expected load, applied to capacity, retries, rate limits, and headroom decisions. Use when deciding "how much buffer is enough" for a system that must not fail under realistic peaks.

Skill Claude Code
Enumerate failure modes, effects, severity, detectability, and mitigations before risky changes.

Skill Claude Code
Cyclic loading failure below yield strength, applied to systems that work fine for years until they suddenly do not. Use when intermittent sub-threshold stress accumulates damage that single-event analysis misses.

Skill Claude Code
Analyze retries, queues, rate limits, cancellations, streaming, and reactive loops for stability.

Skill Claude Code
Order-of-magnitude back-of-envelope reasoning for capacity, latency, cost, and feasibility — before optimizing or designing.
not rated 3 5mo ago A 28 tokens
Skill Claude Code
Reason about iterative systems — retries, type checkers, schedulers, autoscalers, eventual consistency, dataflow — using fixed points, convergence, and contraction.
not rated 3 5mo ago A 39 tokens
Skill Claude Code
Sports technique discipline applied to engineering quality under pressure. Use when deadlines, incidents, or fatigue threaten the discipline that prevents the next failure.

Skill Claude Code
Discover system invariants and mathematical properties, then design logical rules that can be verified with assertions, contracts, or tests.

Skill Claude Code
Risk transfer and pooling — design redundancy, error budgets, multi-region, backups, and on-call as deliberate insurance instruments with explicit premiums.
not rated 3 5mo ago A 33 tokens
Skill Claude Code
Apply immunology to defense system architecture — innate vs adaptive layers, self/non-self discrimination, memory, vaccination, and the cost of overreaction.
not rated 3 5mo ago A 33 tokens
Skill Claude Code
Predict how users, maintainers, systems, and attackers respond to rules, defaults, metrics, and rewards.
not rated 3 5mo ago A 27 tokens
Skill Claude Code
Perform blameless incident analysis focused on contributing factors, safeguards, and recurrence prevention.
not rated 3 5mo ago A 20 tokens
Skill Claude Code
Analyze loss, noise, ambiguity, compression, redundancy, and propagation of information across a system.
not rated 3 5mo ago A 23 tokens
Skill Claude Code
Hermeneutics for code, specs, PRs, and error messages — the disciplined practice of charitable interpretation, the hermeneutic circle, and distinguishing reading-out from reading-in.

Skill Claude Code
Reconcile state transitions so every acquire/release, enqueue/dequeue, event/source, and resource/owner pair balances.
not rated 3 5mo ago A 28 tokens
Skill Claude Code
Queueing-theory reasoning for latency, throughput, and utilization. Use when sizing pools, diagnosing tail latency, or trading off concurrency vs response time using L = λW and the utilization/latency curve.
not rated 3 5mo ago A 50 tokens
Skill Claude Code
Choose a strategic maintenance posture (reactive, preventive, predictive, RCM) per subsystem using MTBF, MTTR, criticality, and the bathtub curve — not by default or hype.
not rated 3 5mo ago A 44 tokens
Skill Claude Code
Apply order-book mechanics — bid/ask, queue position, latency arbitrage, batch vs continuous matching — to schedulers, load balancers, and any system that matches supply to demand.
not rated 3 5mo ago A 43 tokens
Skill Claude Code
Choose tech stack, libraries, and tools by property fit using required-vs-desirable specs, weighted decision matrices, Ashby-style trade-off plots, and lifecycle cost — not hype.

Skill Claude Code
Design rules, APIs, quotas, and protocols so the dominant strategy of self-interested participants is the cooperative one. Use when an interface will be used by parties who optimise their own metric and your job is to make the system robust to that.
