--- name: dependabot-pr-review description: Reviews open Dependabot pull requests in the Dart (flutter/dart-intellij-third-party) and Flutter (flutter/flutter-intellij) IntelliJ plugin repositories. Lists each PR with its build status, asks the user which ones to approve, then approves them and applies the "autosubmit" label. --- # Dependabot PR Review Skill This skill triages open Dependabot dependency-bump PRs across the two IntelliJ plugin repositories. It reports build health for each PR, gets explicit user confirmation for each one, then approves the confirmed PRs and applies the `autosubmit` label. > [!IMPORTANT] > Never approve or label a PR that the user has not confirmed. The user may > confirm PRs individually or accept the bulk option covering every PR with a > passing build, but there is no shortcut that approves failing or pending PRs > in bulk. ## How the autosubmit Label Works This skill never merges anything. It approves and labels; the `auto-submit` bot does the merging. Understanding the label's lifecycle explains what this skill is really fixing: 1. Dependabot applies `autosubmit` itself at PR creation, configured under `labels:` in each repo's `.github/dependabot.yml`. 2. The `auto-submit` bot tries to merge, and **removes the label** if any requirement is unmet, leaving a comment explaining why. 3. The label does not come back on its own. The PR stalls until a human resolves the blocker and re-applies it. So an open Dependabot PR **without** the label has already been rejected once, and the comment says why. The two common cases: | Build | Bot's reason | What this skill does | | --- | --- | --- | | `PASS` | "At least 1 approving review is required" | Approving and re-labeling unblocks the merge. This is the main win. | | `FAIL` | A named check failed | Re-labeling is futile; the bot strips it again within minutes. Fix the check first. | > [!WARNING] > Re-applying `autosubmit` to a PR with failing checks does not merge it. The > bot removes the label again and posts another comment. Only approve a failing > PR when the user has explicitly accepted that the label will likely bounce. --- ## Workflow ### Step 1: Choose the Repositories Default to **both** repositories: - `flutter/dart-intellij-third-party` (the Dart plugin) - `flutter/flutter-intellij` (the Flutter plugin) Only narrow the scope if the user explicitly asks for a single repository, in which case pass `--repo ` in the next step. ### Step 2: List the Dependabot PRs and Their Build Status Run the listing script from the `dart-intellij-third-party` workspace root: ```bash dart run .agents/skills/dependabot-pr-review/scripts/list_dependabot_prs.dart \ --output-file "/brain//scratch/dependabot_prs.json" ``` The script is dependency-free, so it runs directly with `dart run` without a `pub get` step. It prints a markdown table and writes the full JSON payload to the scratch file. > [!IMPORTANT] > Check the exit code. `0` means every repository was queried successfully. > `1` means at least one query failed (expired `gh` auth, network problem, > rate limit), and the script prints a `WARNING` naming the failed repos. In > that case the listing is **incomplete**: report the failure to the user and > stop. Never present partial results as "nothing to do". `2` means the > arguments were invalid. Per-PR build status is one of: | Table | JSON | Meaning | | --- | --- | --- | | `PASS` | `passing` | All checks completed successfully (neutral/skipped count as passing). | | `FAIL` | `failing` | At least one check failed, errored, timed out, or was cancelled. | | `PENDING` | `pending` | Checks are still running and none have failed. | | `NO CHECKS` | `noChecks` | No checks are attached to the head commit. | ### Step 3: Present the Results Show the user the table of PRs. For each PR include the repository, PR number and link, the dependency being bumped and its version change, the build status, the current review decision, the mergeable state, and whether the `autosubmit` label is already present. Call out anything that needs judgement before presenting the approval question: - PRs with `FAIL` checks, including the names of the failing checks. - PRs that are still `PENDING`. - PRs that are drafts, are not `MERGEABLE`, or already carry the `autosubmit` label (these usually need no further action). Identify each PR by its **dependency name** (for example `org.jetbrains.kotlin.jvm`) rather than the full PR title. The script parses this out of the Dependabot title, along with the version change, and exposes it in the `Dependency` and `Version` table columns and under `dependency` in the JSON payload. Unrecognized title formats fall back to a cleaned up title. ### Step 4: Ask the User About Each PR Use the `ask_question` tool with a **single multi-select question**. It has one option per PR, so the user can decide individually, plus a bulk option covering every PR whose build passes. Format each option as the user's own response, naming the dependency, for example: - `Approve and label ALL 2 passing PRs — cli_util, org.jetbrains.kotlin.jvm` - `Approve and label dart-intellij-third-party#665 — org.jetbrains.kotlin.jvm 2.4.10 -> 2.4.20 (build PASSING)` - `Approve and label flutter-intellij#8123 — actions/checkout 4 -> 5 (build FAILING: verify-plugin, label will likely bounce)` Guidelines for the question: - Put the bulk **approve all passing** option first, then the individual passing PRs, then `PENDING`, then failing ones. - The bulk option covers only PRs with a `PASS` build. Never offer a bulk option that sweeps in failing or pending PRs; those always require an individual selection. - Name the dependencies the bulk option covers and state the count, so the user knows exactly what they are agreeing to. - Omit the bulk option when fewer than two PRs are passing, since it would duplicate a single individual option. - Annotate non-passing PRs inline so risk is visible at the point of decision, and note that the bot will strip the label from a failing PR. - Exclude PRs that already have the `autosubmit` label, and mention in your message that they were skipped because they are already queued. - If the user asks to be prompted one at a time instead, ask a separate yes/no question per PR. Build the final set of PRs from the union of the selected options, dropping duplicates. For example, selecting the bulk option *and* an individual failing PR approves all passing PRs plus that one failing PR. Any PR not covered by a selected option is left untouched. ### Step 5: Approve and Apply the Label For the selected PRs only, run: ```bash dart run .agents/skills/dependabot-pr-review/scripts/approve_and_label.dart \ --pr flutter/dart-intellij-third-party#665 \ --pr flutter/flutter-intellij#8123 ``` The script approves each PR with `gh pr review --approve` and then applies the `autosubmit` label with `gh pr edit --add-label`. It skips the approval step if the current user has already approved the PR, and it continues past individual failures so one bad PR does not block the rest. Use `--dry-run` to preview the actions without touching GitHub. Merging is the `auto-submit` bot's job and happens asynchronously, so a successful run here means "queued", not "merged". ### Step 6: Report Back Summarize what happened: which PRs were approved and labeled, which were skipped by the user, and any that failed (for example, because the user cannot approve a PR they authored, or lacks write access to apply labels). Include links so the user can follow up. Be precise that labeled PRs are queued rather than merged, and that the bot merges them only once it is satisfied. For any failing PR that was labeled anyway, tell the user to expect the bot to remove the label again. --- ## Notes - Requires the GitHub CLI (`gh`) to be installed and authenticated with write access to both repositories, plus a Dart SDK on the path. - Both scripts are standalone Dart files that import only `dart:` libraries, so no `pubspec.yaml` or `dart pub get` is needed. - Dependabot PRs are identified with `--author "app/dependabot"`. - The label name is configurable via `--label` on both scripts, but `autosubmit` is the correct default for these repositories. - Both scripts support `--help`. ## Bundled Resources - **`scripts/list_dependabot_prs.dart`**: Lists open Dependabot PRs with a normalized CI status summary; writes JSON and prints a markdown table. - **`scripts/approve_and_label.dart`**: Approves the confirmed PRs and applies the `autosubmit` label, queueing them for the `auto-submit` bot.
