Audits the licenses of your project's dependencies for how you actually ship (SaaS, distributed app or library, or internal tool): normalizes license names to SPDX, resolves OR and AND expressions, flags missing, AGPL, GPL, source-available, and incompatible licenses, and writes a ranked fix plan and notices list. Includes a tested stdlib Python auditor.
Reviews a password policy config against NIST SP 800-63B-4, covering length minimums, no composition rules or forced expiry, blocklist checks, rate limiting, paste and Unicode support, no hints or security questions, and safe hashing parameters. Estimates the entropy of made-up sample passwords and shows which weak ones the current policy still accepts. Never asks for real passwords. Includes a stdlib Python checker with --self-test.
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.
