Convert natural language scheduling descriptions into valid cron expressions. Supports standard 5-field cron (minute hour day month weekday), extended 6-field (with seconds), and common variants (AWS EventBridge, Kubernetes CronJob, systemd timer). Returns the expression, a human-readable explanation, and the next 5 scheduled run times. Deterministic: same input always yields same output.

Generate conventional commit messages from git diffs or change descriptions. Outputs type(scope): subject with optional body and footer. Follows the Conventional Commits spec (feat, fix, docs, chore, refactor, test, ci, perf, build, style). Deterministic: same diff always yields same message. Detects breaking changes, multiple scopes, and co-authors.

Generate comprehensive, well-structured pull request descriptions from git diffs and commit history. Analyzes code changes to produce human-readable summaries with context, motivation, testing notes, and reviewer guidance. Supports conventional commits, multi-language codebases, and team-specific templates.

Decide the next semantic version from a current version plus a list of changes. Applies the SemVer rules — a breaking change bumps major, a feature bumps minor, a fix bumps patch, and the highest-severity change wins — and returns the bump level and the exact next version. Deterministic release automation for agents.

Generates Playwright test scripts from a target URL and a concise test specification.

Run a prompt or command on a recurring interval, or self-paced, until a condition is met — for polling status, babysitting long jobs, or repeating a task.
