/tend-pr - PR Lifecycle Automation

Goal

Set up a PR for review and start a polling loop that tends it to merge-readiness. Each iteration is handled by /tend-pr-tick. This skill handles setup only, then delegates iteration work.

Two modes:

Manifest-aware: When given a manifest (or one is inferrable from conversation context), routes fixes through manifest amendment + scoped /do. The manifest is the intermediary — no direct code fixes.
Babysit: When no manifest is available, fixes actionable comments directly. Same classification and loop structure, but without the manifest intermediary.

Input

$ARGUMENTS = manifest path, PR URL, or omitted. Optionally with --platform <platform>, --interval <duration>, --reviewers <usernames>, and --log <execution-log-path>.

Mode detection:

If argument is a file path ending in .md pointing to an existing manifest → manifest-aware mode
If no argument but conversation context contains a manifest path from a prior /do or /define run → manifest-aware mode (use the inferred manifest)
If argument is a PR URL or no manifest is inferrable → babysit mode (identify the PR from the argument URL or from the current branch)
