Tokens do the rest.

Aquarium Crash Card

For the new or intermediate freshwater fishkeeper who walks downstairs to a cloudy tank, a gasping fish at the surface, or a dead corydoras on the gravel, and has 20 minutes to figure out whether the tank is cycling, crashing, poisoning, or infected. Tell the tool the tank size, days since setup, livestock, test-kit readings and visible symptoms, and one structured pass returns a ranked emergency card: top 2 to 3 diagnoses in descending confidence, the exact next 60 minutes of action, a tank-sized water-change plan with Seachem Prime dosing in mL, a do-not-do list, assumptions receipts for every blank reading, and safety notes that fire on saltwater, dropsy, test-strip readings, overstocking, or an uncycled tank.

Homebrew Off-Flavor Fixer

For the home brewer who just cracked open the first bottle of a six-week batch and tastes something wrong, a sour that should not be sour, a buttery that should not be buttery, a weird plasticky phenol, or a cardboard note, and now has 44 bottles sitting in the closet waiting on a drink-vs-dump decision. Tell the tool the beer style, yeast strain, pitch temperature, fermentation temperature profile, days in primary, days in secondary, days bottle-conditioned, water source, cleaner and sanitizer used, and the off-flavor descriptors from a checklist of 17. One structured pass returns a diagnosis card: top 2 to 3 ranked root causes (sanitation, under-pitched yeast, fermentation temp too high or low, no diacetyl rest, oxidation, light-struck, DMS short boil, water chemistry mismatch, yeast strain ester profile, cold-side infection), the exact process change for next brew (lower pitch temp by 4 F, add diacetyl rest, swap cleaner, closed transfer), whether the current batch can be aged out or should be dumped, and a one-line sensory test the brewer can run on bottle 2 to confirm. Hard refusals fire for methanol fear questions, pressure-canned wort (botulism trap), gluten-free grain bills, proprietary house or brewpub yeast strains, and out-of-scope styles (sour and wild, mead and cider, distillate).

Print Fail Fix Card

For the 3D printing hobbyist whose print just failed at midnight and who is one tab away from posting a photo to r/FixMyPrint hoping someone diagnoses it before morning. Tell the tool the printer, slicer, filament, the failure symptom and whatever settings you remember, and one structured pass returns a ranked diagnosis card: two or three ranked candidate causes with per-cause settings-delta tables in your slicer's dialect, a one-line physical-inspection step, a short test-print recipe with a time estimate, an assumptions receipt list for every blank field, and a one-line closing message that routes you when the failure is actually a resin print, a structural part, or a thermal-runaway signature.

Sourdough Starter Rescue

For the home baker whose sourdough starter is on day 7, is not rising, smells like nail polish remover, or just produced a brick instead of a loaf. Tell the tool days since last feed, days since created, flour type, feeding ratio, ambient kitchen temperature, water type, container type, visible symptoms (hooch layer, bubble pattern, smell, mold), and whether it has risen before. One structured pass returns a rescue card: ranked diagnoses (false rise, lag phase, overfed, underfed, hooch and hungry, too cold, chlorinated water, contaminated, dead) with plain-English explanations, the exact next three feeds in grams and ratios with timing, a pivot rule for feed 3, and a bake-day float-test go/no-go with pass criteria. Hard refusals fire for fuzzy or pink or orange or blue or green mold (discard the starter and container), gluten-free flours (route to a GF guide), and non-wheat-non-rye flours.
