Builds a day-by-day exam revision timetable from your exam dates, subject weights and confidence. Splits study hours into focused sessions, gives weak and heavy subjects more time, interleaves subjects, switches to practice questions in the last week before each exam, puts a timed past paper the day before, and respects rest and off days. Flags too few sessions per topic and back-to-back exams. Includes a stdlib Python planner with --self-test.
Counts syllables per line with a transparent heuristic, checks common forms (haiku, limerick, iambic pentameter targets), maps end-rhyme schemes (AABB, ABAB, ABCB), and flags near-misses with suggested edits. Use when a user asks "does this scan?", "is this a haiku?", or "what is my rhyme scheme?". Includes a tested stdlib Python checker.
Compares commute options - car (fuel or EV), transit, bike, e-bike, walking, day-share mixes and park-and-ride legs - per month and year with cash cost, door-to-door time, time cost at your own hourly value, cost per trip and CO2. Picks pass vs pay-per-ride for the days you ride, separates car running costs from fixed costs, and shows the break-even value of an hour. Includes a stdlib Python calculator with --self-test.
Builds a houseplant watering check calendar from a list of plants with pot size and material, light, drainage and last watering date. Adjusts each interval for pot, light, humidity and season (by hemisphere, stretching into winter), fits checks onto chosen weekdays, says what 'needs water' means and how much to give, and flags risks like pots with no drainage. Includes a stdlib Python planner with .ics export and --self-test.
Lints a DNS zone file or a provider's CSV record export before it breaks web or mail - CNAME at the apex or next to other records, MX/NS pointing at a CNAME or IP, missing trailing dots, missing or duplicate SPF, +all/?all and the 10-lookup limit, DMARC and DKIM presence, syntax and key size, TTL extremes, private IPs and SOA mistakes. Returns corrected records. Includes an offline stdlib Python linter with --self-test.
