Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.
-
tibsfox Skill Time Series AnalysisAnalyzing and forecasting data ordered in time. Covers stationarity and differencing, autocorrelation (ACF and PACF), AR, MA, ARMA, and ARIMA models, the Box-Jenkins methodology, seasonality and SARIMA, forecasting with prediction intervals, and residual diagnostics including the Ljung-Box test. Use when data is indexed by time, when forecasting future values, when detecting trend or seasonality, or when checking whether residuals still carry structure.
-
tibsfox Bundle Intelligence InvestigatorGenerate 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 hypothesis + acknowledged uncertainty + confidence label and ranked moves, then writes the result back to the KB. Always trigger this skill for these request types — do not generate briefings manually.
-
tibsfox Skill Digital Logic DesignDesign and analysis of combinational and sequential digital circuits using Boolean algebra, truth tables, K-maps, CMOS gate implementation, flip-flops, registers, counters, and finite state machines. Covers De Morgan's theorems, canonical sum-of-products and product-of-sums forms, minimization techniques, propagation delay, setup and hold times, metastability, synchronous design discipline, and FSM encoding. Use when designing, minimizing, verifying, or debugging any circuit whose signals take only discrete logic values.
-
tibsfox Skill Decision Framework InvokerTriggers for automatically invoking the decision-framework skill before irreversible or high-blast-radius operations. Use as a checkpoint: when a proposed action matches a trigger pattern, pause and run the appropriate framework (first-principles, inversion, decision matrix, second-order thinking) before proceeding. Prevents ad-hoc calls from becoming regret.
-
tibsfox Skill Analog Circuit DesignDesign of active analog circuits built around operational amplifiers and discrete gain stages — inverting, non-inverting, difference, and instrumentation topologies, negative feedback and loop stability (gain-bandwidth product, phase margin, compensation), active filters (Sallen-Key, multiple-feedback biquad), sinusoidal and relaxation oscillators, comparators and Schmitt triggers, voltage references (bandgap, shunt, series), and linear versus switching voltage regulators. Covers how to pick a topology, close a feedback loop that stays stable, set gain and bandwidth, and choose a power-conversion approach. Use when designing an amplifier, filter, oscillator, reference, comparator, or regulator, or when reasoning about feedback stability, loop gain, phase margin, or op-amp non-idealities.
-

ariffazil Skill Arifos Eight Verb Canonical ChainThe canonical 8-verb authority chain for arifOS kernel operations. USE WHEN: any kernel interaction — 'init session', 'gather evidence', 'reason', 'route to organ', 'recall memory', 'constitutional verdict', 'governed execution', 'seal to VAULT999'. Chain: arif_init (000 session bind — ALWAYS first) → arif_observe (111 sense with epistemic tags) → arif_think (333 structured reasoning) → arif_route (444 intent→organ dispatch) → arif_memory (555 L1-L6 governor) → arif_judge (666 SEAL/HOLD/SABAR/VOID) → arif_forge (777 execution gate — mutates only after SEAL) → arif_seal (999 VAULT999 append — irreversible). Iron rules: never skip a gate (OBSERVE before REASON, JUDGE before EXECUTE); only arif_seal writes VAULT999; only A-FORGE mutates production; kernel's no is final — never self-authorize past a refused capability check.
