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

Observational cosmology from Hubble's law to the CMB. Covers redshift, Hubble expansion, the cosmological parameters, the cosmic microwave background, large-scale structure, galaxy rotation curves and dark matter, Type Ia SNe and dark energy, and the current state of Lambda-CDM. Use when reasoning about the large-scale universe, interpreting cosmological surveys, or teaching the Big Bang evidence

Voice, style, and register in writing across all forms. Covers voice (authorial presence, authenticity, persona, tone), style as choice (diction, syntax, rhythm, density, register), the elements of style (Strunk's principles, economy, parallel construction, definite/specific/concrete language), distinctive voices (stream of consciousness, minimalism, maximalism, vernacular, lyric, journalistic), s

Embedded firmware development for microcontrollers including memory-mapped I/O, GPIO, interrupts, timers, UART/SPI/I2C serial protocols, PWM generation, ADC sampling, interrupt-driven versus polled architectures, RTOS fundamentals, and the bring-up sequence from power-on reset through first printf. Covers AVR/Arduino, ARM Cortex-M, and ESP32 patterns. Use when writing, porting, debugging, or revie
