lyndonkl Skill

Reads and updates the FIFA World Cup Fantasy tournament state machine (footballfantasy/context/tournament-state.md) — the temporal backbone tracking phase (pre-tournament → group MD1-3 → R32 → R16 → QF → SF → final), budget ($100m group / $105m knockouts), nation cap (3 group, loosening in knockouts), chips remaining, surviving nations, each owned player's elimination-risk horizon, and deadlines. Validates state on load (count/feasibility checks), applies phase transitions, and appends to the append-only state log (never silent overwrite). Use to load state at the start of a run and to commit state changes after the manager makes a move.

lyndonkl Bundle

Generates structured experimental designs (factorial, response surface, Taguchi) to systematically discover how multiple factors affect outcomes while minimizing experimental runs. Use when optimizing multi-factor systems with limited experimental budget, screening many variables to find the vital few, discovering interactions between parameters, mapping response surfaces for peak performance, validating robustness to noise factors, or when users mention factorial designs, A/B/n testing, parameter tuning, or process optimization.

lyndonkl Skill

The mutation operator for the FIFA World Cup Fantasy evolution engine. Applies small, bounded, feasibility-preserving perturbations to a recombined offspring squad/plan — swap one differential for an adjacent-price alternative, reorder the bench by kickoff, shift one captain-ladder step, try one fixture-swing transfer, nudge one enabler. Mutation rate is low by default and raised on demand by the diversity governor when the population has collapsed. Each mutation stays inside budget/nation/formation feasibility. Use in the mutate stage after recombination, or when wc-population-diversity calls for more exploration.

lyndonkl Skill

For each spending category, computes current-period spend, 6-month rolling average, year-over-year delta, and budget variance, then flags categories that are outliers (>1.5x rolling average or >130% of budget). Produces a ranked list of categories that grew, shrank, or stayed flat, plus the top transactions driving each outlier. Use for monthly spending reviews, identifying lifestyle creep, evaluating budget adherence, or when user mentions category trends, spending changes, budget variance, or outlier spend.

lyndonkl Bundle

Values companies the standard DCF cannot handle, across five branches — distress (failure probability from a bond price or rating, blended with the distress-sale outcome), financial service firms (equity excess return and FCFE against regulatory capital, since a bank gets no FCFF and no optimal debt ratio), private companies (total beta for an undiversified owner, Silber and bid-ask illiquidity discounts), cyclical and commodity firms (mid-cycle normalized earnings), and young negative-earnings firms (a revenue and margin path plus survival odds, emitted as a dcf-valuation-engine payload). Also walks a private owner's value to an IPO offer price line by line. Use when valuing a bank, insurer, startup, distressed firm, private business, miner or deep cyclical, when pricing an IPO or a sale to a public buyer, or when asked about probability of distress, total beta, illiquidity discount, excess return models, normalized earnings, or negative-earnings valuation.

lyndonkl Bundle

Computes the optimal shaded bid for a first-price sealed-bid auction given a true private value, an estimate of the number of competing bidders N, and a value-distribution assumption. Implements the `(N-1)/N` equilibrium shading rule for uniform private values, adjusts for log-normal or empirical value distributions, layers a risk-aversion adjustment, and caps output against the bidder's remaining budget. Domain-neutral auction theory reusable across fantasy sports (baseball FAAB, NBA/NHL waiver auctions), prediction-market limit sizing, sealed procurement bids, and any blind-bid context. Use when user mentions "first-price auction bid", "sealed bid shading", "(N-1)/N", "FAAB bid amount", "auction shading", "optimal bid first-price", "bid for sealed-bid", "blind bid sizing", or when downstream logic needs a principled shade factor rather than an ad-hoc heuristic.

lyndonkl Bundle

Turns limitations into creative fuel by strategically imposing constraints that force novel thinking, break habitual patterns, and reveal unexpected solutions. Covers resource constraints (budget/time/tools), format constraints (length/medium), rule-based constraints, and perspective constraints. Use when brainstorming feels stuck or generates obvious ideas, working with limited resources, designing with specific limitations, or when user mentions "think outside the box", "we're stuck", "same old ideas", "tight constraints", or "limited budget/time".

lyndonkl Bundle

Evaluates a discrete investment, project or acquisition from its cash flow stream — NPV, IRR with every root reported when the stream has more than one, MIRR, profitability index and project selection under a capital budget, equivalent annuities and replication for unequal lives, payback and discounted payback, project return on capital and EVA, synergy value with the ceiling price it supports, the value of control and its expected value, the four-number acid test for a deal, and control premiums and minority discounts. Use when deciding whether to take a project, ranking competing projects, comparing projects with different lives, sizing a capital budget, testing whether a stream is truly incremental, valuing synergy or control, pricing a majority or minority stake, or setting the maximum price for an acquisition.

lyndonkl Skill

The recombination operator for the FIFA World Cup Fantasy evolution engine. Crosses elite candidate squads/plans at BUILDING-BLOCK boundaries (Captain Core, Clean-Sheet Spine, Mid-Engine, Differential Pod, Enabler Bench; or for matchday plans the XI/captain-ladder/bench/sub/chip blocks) — harvesting the strongest module from each parent rather than swapping individual players — then runs a feasibility REPAIR operator (budget, nation cap, formation, 15-man shape) that restores legality from the cheapest block first and never guts a value-bearing block. Records block lineage (which parent each block came from). Implements the Evolution document's central lesson that naive crossover destroys good building blocks. Use in the recombine stage after fitness selection.

posthog-skills Bundle

Qualify and draft outreach for PostHog product-led leads who are hitting a billing transition — either startup program customers rolling off free credits, or users whose first invoice will be >= $2K. Use this skill when a TAE needs to work a startup rolloff lead, a high first-invoice alert, or any lead where the matching criteria mentions 'startup rolloff', 'credit spend', 'first invoice', 'credits expiring', or 'high usage transition'. Also trigger when a TAE pastes Salesforce lead details with matching criteria like 'Startup rolloff + high credit spend' or 'First invoice >= $2K'.
