Security hygiene for GSD's self-modifying skill and agent system. Use this skill whenever: creating, editing, or deleting skill files (.claude/skills/, .claude/commands/), modifying agent definitions (.claude/agents/), working with YAML configuration or chipset files, handling JSONL observation data (.planning/patterns/), processing community-contributed skills or chipsets, any file path operation

Experimental design principles for scientific inquiry. Covers variable identification and control, control groups (positive and negative), randomization, blinding, sample size and power, replication strategies, factorial designs, quasi-experimental approaches, and common design pitfalls. Use when designing, reviewing, or teaching about controlled experiments in any scientific discipline.

Historical argumentation, evidence-based writing, and oral history methods. Covers thesis development for historical arguments, evidence selection and deployment, counterargument construction and rebuttal, historical writing conventions, and the methodology of oral history as both source and practice. Use when constructing historical arguments, writing analytical essays, conducting oral history in

Craft methodology for the trades — how skilled work is organized, decomposed, sequenced, and evaluated from first principles through finished artifact. Covers the craft arc (intent, layout, roughing, fitting, finishing, inspection), the distinction between process knowledge and product knowledge, and how craft traditions encode error-correction in their sequencing. Use when designing a new trade p

The household as an economic unit with income, expenses, savings, and debt. Covers the envelope method, fixed vs variable expenses, the 50-30-20 baseline, emergency reserves, the true cost of ownership, opportunity cost in household decisions, and the distinction between a budget and a spending plan. Use when building a household budget, diagnosing why a household is always over, planning a major

Generate intelligence briefings for the planning dashboard. Use this skill whenever a request file appears in `.planning/console/inbox/pending/` whose `type` field starts with `intelligence.` (refresh_briefing, triage_finding, snapshot_diff, investigate_section, dismiss_finding). The skill reads the per-project KB at `.gsd/intelligence/intelligence.db`, synthesizes a briefing with a causal hypothe

Active listening techniques for effective communication. Covers attending behaviors, paraphrasing, reflective listening, clarifying questions, empathic response, barriers to listening, listening in conflict, and cross-cultural listening. Use when building listening skills, improving understanding in conversation, mediating disputes, or analyzing communication breakdowns.

Thermodynamics from the zeroth law through statistical mechanics. Covers temperature and thermal equilibrium, heat transfer mechanisms (conduction, convection, radiation), the first law (internal energy, work, heat), PV diagrams, thermodynamic processes (isothermal, adiabatic, isobaric, isochoric), the second law (entropy, Carnot cycle, heat engines, refrigerators), Boltzmann's statistical interpr

Proof writing and verification techniques for mathematical reasoning. Covers 13 proof strategies with canonical worked examples — direct, contrapositive, contradiction, cases, WLOG, vacuous/trivial, biconditional, counterexample, existence (constructive and non-constructive), uniqueness, induction (weak, strong, structural), pigeonhole/double-counting, and diagonal argument/invariants. Use when wr

OpenStack Horizon web dashboard skill. Use when deploying, customizing, or troubleshooting the OpenStack web UI. Covers panel customization, session management, multi-domain support, theme branding, TLS configuration, and common dashboard failure modes including login issues, missing panels, and static asset problems.

Mathematical foundations of uncertainty and random phenomena. Covers sample spaces, events, axioms, conditional probability, Bayes' theorem, independence, random variables, distributions (discrete and continuous), expected value, variance, the law of large numbers, and the central limit theorem. Use when computing probabilities, reasoning about random events, working with probability distributions

Interpretive methods for analyzing literary texts including fiction, poetry, drama, and creative nonfiction. Covers narrative elements (character, plot, setting, point of view, theme), literary devices (symbolism, imagery, irony, foreshadowing, allusion), critical lenses (formalist, reader-response, historical, feminist, postcolonial, psychoanalytic, Marxist), close reading of prose and poetry, in
