Shipment Tracker

Analyze one or more GitHub repositories to visualize what was shipped over a specified time period. Creates an interactive HTML report showing merged pull requests and closed issues with timeline visualization.

When to Use

• User asks "what was shipped in the last X days/weeks/months"
• User wants to see a report of completed work across repositories
• User requests a "shipment report" or "delivery timeline"
• User wants to visualize team progress over a quarter or sprint
• User asks for examples: "show me what we shipped last quarter" or "what went out in the past 30 days"

Instructions

1. Parse Time Period

Accept natural language time periods from the user:

• "past 30 days" / "last 30 days"
• "last week" / "past week"
• "last month" / "past month"
• "last quarter" / "past 90 days"
• "last 6 months"
• "since YYYY-MM-DD"
• "between YYYY-MM-DD and YYYY-MM-DD"

Convert to ISO 8601 date format for GitHub API queries.

2. Gather Repository Information

Ask the user which repositories to analyze:

• Single repo: owner/repo
• Multiple repos: owner/repo1 owner/repo2
• If not specified, use current repository from git remote

3. Fetch Data with GitHub CLI

For each repository, fetch:

Merged Pull Requests:

gh pr list \
  --repo owner/repo \
  --state merged \
  --search "merged:>=YYYY-MM-DD" \
  --json number,title,author,mergedAt,url,labels \
  --limit 1000

Closed Issues:

gh issue list \
  --repo owner/repo \
  --state closed \
  --search "closed:>=YYYY-MM-DD" \
  --json number,title,author,closedAt,url,labels \
  --limit 1000

4. Generate HTML Report

Use the helper script scripts/generate-report.py to create an interactive HTML page:

python3 scripts/generate-report.py \
  --repos "owner/repo1,owner/repo2" \
  --since "2024-01-01" \
  --until "2024-03-31" \
  --output shipment-report.html

The script will:

• Parse JSON data from gh CLI
• Group items by repository and type (PR/Issue)
• Create a timeline visualization
• Generate statistics (total shipped, by author, by label)
• Include filtering and sorting capabilities
• Create a standalone HTML file with embedded CSS/JS

5. Open the Report

open shipment-report.html
# or on Linux:
xdg-open shipment-report.html

Output Format

The generated HTML report includes:

1. Summary Section

   • Total PRs merged
   • Total issues closed
   • Date range analyzed
   • Repositories included
   • Top contributors

2. Timeline Visualization

   • Interactive timeline showing when items were shipped
   • Color-coded by type (PR vs Issue)
   • Grouped by repository

3. Detailed Lists

   • Filterable and sortable tables
   • Links to GitHub items
   • Author information
   • Labels and metadata

4. Charts

   • Shipment velocity over time
   • Breakdown by repository
   • Contribution distribution

Examples

Example 1: Single Repository, Last 30 Days

User: "Show me what was shipped in the past 30 days"

Agent Actions:

1. Determine current repo: gh repo view --json nameWithOwner
2. Calculate date 30 days ago
3. Fetch merged PRs: gh pr list --state merged --search "merged:>=2024-12-06" --json number,title,author,mergedAt,url,labels --limit 1000
4. Fetch closed issues: gh issue list --state closed --search "closed:>=2024-12-06" --json number,title,author,closedAt,url,labels --limit 1000
5. Generate report: python3 scripts/generate-report.py --repos "owner/repo" --since "2024-12-06" --output shipment-report.html
6. Open report

Example 2: Multiple Repositories, Last Quarter

User: "Create a shipment report for github/copilot and github/copilot-cli for last quarter"

Agent Actions:

1. Parse time: "last quarter" = past 90 days
2. Calculate date: 90 days ago from today
3. For each repo, fetch merged PRs and closed issues
4. Generate combined report: python3 scripts/generate-report.py --repos "github/copilot,github/copilot-cli" --since "2024-10-07" --output shipment-report.html
5. Open report

Example 3: Custom Date Range

User: "Show what we shipped between January 1st and March 31st 2024"

Agent Actions:

1. Parse dates: since="2024-01-01", until="2024-03-31"
2. Fetch data for date range
3. Generate report: python3 scripts/generate-report.py --repos "owner/repo" --since "2024-01-01" --until "2024-03-31" --output shipment-report.html
4. Open report

Notes

Date Parsing

• Use ISO 8601 format (YYYY-MM-DD) for GitHub API queries
• "Last quarter" = 90 days
• "Last month" = 30 days
• "Last week" = 7 days
• Always calculate dates relative to current date

API Limits

• GitHub CLI uses authenticated requests (higher rate limits)
• Each query returns up to 1000 results
• For very active repos, consider narrower time ranges
• The skill will warn if hitting limits

Filtering Considerations

• Only includes merged PRs (not closed without merging)
• Only includes closed issues (not open)
• Draft PRs are excluded
• Private repositories require appropriate permissions

Performance

• Fetching data for multiple repos is done in parallel when possible
• Large datasets (hundreds of items) may take 10-30 seconds to process
• Generated HTML is standalone and works offline after creation

Customization

Users can request:

• Filtering by labels: "only show PRs with label:bug"
• Filtering by author: "only show @username's contributions"
• Grouping preferences: by week, by month, by repository
• Chart types: timeline, bar chart, pie chart

Error Handling

If a repository is not accessible:

• Skip it and continue with other repos
• Show a warning in the report
• Don't fail the entire operation
