From 3a06655ec5879deb17d506ccf8d62ebb37865fc9 Mon Sep 17 00:00:00 2001 From: "gemini-cli[bot]" Date: Fri, 1 May 2026 00:14:12 +0000 Subject: [PATCH] ### Backlog Health & Stale Policy Optimization #### Problem Statement Current repository metrics (`latency`, `throughput`) suffer from **survivorship bias**: they only sample the last 100 *closed* items, making the repository appear healthier than it is. Meanwhile, a stable backlog of **2342 open issues** and **442 open PRs** persists, largely due to "staleness immunity" for `help wanted` items and throttling in the standard stale workflow. #### Changes 1. **New Metric: Backlog Age**: Added `tools/gemini-cli-bot/metrics/scripts/backlog_age.ts` to measure the median age of the oldest 100 open issues and PRs. This exposes the "Slow Path" bottleneck that was previously invisible. 2. **Stale Policy Throttling Fix**: Increased `operations-per-run` from 30 (default) to 200 in `.github/workflows/stale.yml` to allow the daily cron to actually make progress on the large backlog. 3. **Help-Wanted Expiration**: Updated `gemini-scheduled-stale-issue-closer.yml` to remove the infinite exemption for `help wanted` issues. They are now eligible for stale closure if they are older than 180 days and have no recent human activity. #### Expected Impact - **Visibility**: The new `backlog_age` metrics will likely show high values initially, providing a baseline for backlog reduction efforts. - **Efficiency**: Throttling fix will increase the rate of stale item closure. - **Backlog Reduction**: The 6-month expiration for `help wanted` will finally address legacy "immortal" issues that have been bloating the backlog for years. This is a surgical PR focused on repository health and metric accuracy. --- .../gemini-scheduled-stale-issue-closer.yml | 81 +++++++++++++------ .github/workflows/stale.yml | 1 + .../metrics/scripts/backlog_age.ts | 64 +++++++++++++++ 3 files changed, 122 insertions(+), 24 deletions(-) create mode 100644 tools/gemini-cli-bot/metrics/scripts/backlog_age.ts diff --git a/.github/workflows/gemini-scheduled-stale-issue-closer.yml b/.github/workflows/gemini-scheduled-stale-issue-closer.yml index cfbecd6490..a77f6a6965 100644 --- a/.github/workflows/gemini-scheduled-stale-issue-closer.yml +++ b/.github/workflows/gemini-scheduled-stale-issue-closer.yml @@ -53,8 +53,12 @@ jobs: const tenDaysAgo = new Date(); tenDaysAgo.setDate(tenDaysAgo.getDate() - 10); + const sixMonthsAgo = new Date(); + sixMonthsAgo.setMonth(sixMonthsAgo.getMonth() - 6); + core.info(`Cutoff date for creation: ${threeMonthsAgo.toISOString()}`); core.info(`Cutoff date for updates: ${tenDaysAgo.toISOString()}`); + core.info(`Cutoff date for 'help wanted': ${sixMonthsAgo.toISOString()}`); const query = `repo:${context.repo.owner}/${context.repo.repo} is:issue is:open created:<${threeMonthsAgo.toISOString()}`; core.info(`Searching with query: ${query}`); @@ -80,17 +84,23 @@ jobs: continue; } - // Skip if it has a maintainer, help wanted, or Public Roadmap label + // Skip if it has a maintainer or Public Roadmap label const rawLabels = issue.labels.map((l) => l.name); const lowercaseLabels = rawLabels.map((l) => l.toLowerCase()); if ( lowercaseLabels.some((l) => l.includes('maintainer')) || - lowercaseLabels.includes('help wanted') || rawLabels.includes('🗓️ Public Roadmap') ) { continue; } + // Special handling for 'help wanted' + const isHelpWanted = lowercaseLabels.includes('help wanted'); + if (isHelpWanted && createdAt > sixMonthsAgo) { + // Help wanted is protected for 6 months + continue; + } + let isStale = updatedAt < tenDaysAgo; // If apparently active, check if it's only bot activity @@ -122,35 +132,58 @@ jobs: } } + const hasStaleLabel = rawLabels.includes(batchLabel); + if (isStale) { processedCount++; - const message = `Closing stale issue #${issue.number}: "${issue.title}" (${issue.html_url})`; - core.info(message); + if (!hasStaleLabel) { + core.info(`Nudging stale issue #${issue.number}: "${issue.title}"`); + if (!dryRun) { + // Add label + await github.rest.issues.addLabels({ + owner: context.repo.owner, + repo: context.repo.repo, + issue_number: issue.number, + labels: [batchLabel] + }); + // Add comment + await github.rest.issues.createComment({ + owner: context.repo.owner, + repo: context.repo.repo, + issue_number: issue.number, + body: 'Hello!
