Audits a repository's remote branches and plans a safe cleanup. Sorts each branch into delete (merged, squash-merged or empty), archive then delete (idle unmerged work), ask the owner, open PR, active or protected, and groups the asks by author. Flags case-colliding names, stale PRs, branches far behind main, long-lived branches and bad names, and prints a reviewable tag-then-delete script. Includes a stdlib Python auditor with --self-test.
Reviews and rewrites Git commit messages to Conventional Commits quality — clear type/scope, imperative subject, useful body explaining why — and trains the author with concrete before/after feedback.
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.
Finds fair meeting times for distributed teams. Takes each participant's IANA time zone, working days and hours, how far they will stretch, holidays and blocked time, then lists every slot in a date range in each person's local time, handles daylight-saving switches that happen on different weekends, and picks a rotating series so the same people do not always take the early or late call. Includes a stdlib Python zoneinfo script with --self-test.
Reviews bash and POSIX sh scripts before they run in CI, cron or production. Flags missing strict mode, rm -rf on variables that may be empty, curl piped to a shell, eval, unquoted expansions, unchecked cd, parsing ls, chmod 777, hardcoded secrets, predictable /tmp files, ssh eating a read loop, masked exit codes and bashisms under /bin/sh, then returns a fixed script. Includes a stdlib Python linter with --self-test.
