About this skill

/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:

  1. If argument is a file path ending in .md pointing to an existing manifest → manifest-aware mode
  2. If no argument but conversation context contains a manifest path from a prior /do or /define run → manifest-aware mode (use the inferred manifest)
  3. 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)

PR resolution (babysit mode without a PR URL argument): Look up the open PR for the current branch. If no open PR exists, error and halt — babysit mode requires an existing PR to tend (it does not create PRs).

Flags:

  • --platform: PR platform. Default: github. Controls how PR operations (create, read comments, check CI) are performed.
  • --interval: Polling interval for /loop. Default: 10m. Accepts duration format (e.g. 5m, 15m).
  • --reviewers: Comma-separated usernames to request review from (e.g. --reviewers alice,bob). Optional — if omitted, no reviewers are requested.
  • --log: Path to the /do execution log from a prior run. Used in manifest-aware mode to pass to scoped /do invocations. Optional — if omitted, locate the most recent /tmp/do-log-*.md or from conversation context.

Errors:

  • No argument, no manifest inferrable, and no open PR for current branch: "Error: No manifest or open PR found. Provide a manifest path or PR URL. Usage: /tend-pr [--platform github] [--interval 10m] [--reviewers user1,user2]"
  • --platform value not supported: "Error: Platform '' not yet supported. Currently supported: github"

Multi-Repo PR Sets

When the manifest declares Repos: in Intent (multi-repo changeset), each repo's PR is tended by its own /tend-pr invocation pointing at the same canonical /tmp manifest. PR descriptions stay summary-only — manifests are internal and never embedded in PRs.

All /tend-pr-tick instances amend the same shared manifest. There is no locking and no concurrency engineering. Concurrent amendments are last-writer-wins; the later write may overwrite the earlier write's amendment block. Recovery: the user notices the missing amendment in the next iteration and re-triggers the lost tick (e.g., re-add the comment, re-run /tend-pr-tick). Do not add file locking — collisions are rare and the recovery cost is small.

Single-repo manifests (no Repos: field) are unaffected — one /tend-pr, one PR, no shared-manifest considerations.

Full convention: references/MULTI_REPO.md (in define/references/) §f.

Setup

Manifest-aware mode: Ensure a non-draft PR exists for the current branch — create one if none exists. Use the manifest's Intent section for PR title/description. If --reviewers was provided, request review from those users. Resolve the execution log path (from --log, most recent /tmp/do-log-*.md, or conversation context).

Babysit mode: The PR must already exist (resolved during input). If --reviewers was provided, request review from those users.

Create a log file at /tmp/tend-pr-log-{pr-number}.md.

Output the PR link: "PR ready for review: "

Start Loop

Build the tick arguments based on mode:

  • Manifest-aware: <pr-number> manifest <manifest-path> <log-path>
  • Babysit: <pr-number> babysit

Invoke the /loop skill with: <interval> /tend-pr-tick <tick-arguments>

The tick handles its own lifecycle — terminal states (merge-ready, merged, closed, draft, escalation) are handled within the tick, including user interaction and loop termination.
