Sky Map Release Assistant

Procedures

1. Data Retrieval

• When a user provides a tag (e.g., "v2.1.0"), execute: python3 tools/generate_changelog.py [TAG]
• This returns a JSON object with release_date, commits, closed_issues, and merged_prs.
• Do not ask the user for a date. Use the release_date provided by the tool.

2. Pre-flight: Read Existing Output Files

Before drafting, read both output files if they exist:

• app/src/main/res/values/whatsnew_content.xml
• fastlane/metadata/android/en-US/changelogs/default.txt

This skill may be run multiple times before a release. Treat the existing content as cumulative output from previous runs — preserve all existing items and only add changes not yet covered.

3. Synthesis Logic

• Prefer merged_prs descriptions over raw commit messages — PR authors write summaries for review.
• Match commit messages to issue numbers where helpful.
• Prioritize issue titles over commit messages for clarity.
• Re-evaluate the best items across all changes since the tag (not just new ones) when updating default.txt.
• If the user provides additional instructions (e.g., "focus on UI"), prioritize those items.

4. Output Generation

Target A: whatsnew_content.xml in app/src/main/res/values/

• Use <h2> for each feature heading followed by a short descriptive paragraph.
• Only use <ul><li> to group multiple minor items under a single heading.
• Keep it concise. If possible, ensure the "Support Sky Map" section (appended separately) stays above the fold, but this is not a hard requirement.

Target B: Fastlane metadata default.txt under fastlane/metadata/android/en-US/changelogs

• STRICT TOTAL LIMIT: 350 CHARACTERS — verify with wc -m after writing.
• Use <b><font color="#F67E81">Section</font></b> headings to group items.
• Select the most impactful 2-3 changes from the full set since the tag.
• Provide the character count at the end.

Target C: Markdown for a release on GitHub.

-- The output should be prepended to the CHANGELOG.md file and use GitHub markup. -- The release notes here can be more thorough and detailed that targets A and B. -- The target audience is users who are developers themselves or who are comfortable installing the app from other other sources than the Google Play Store.

Instructions

• Always perform the Python tool call first before drafting.
• Always read existing output files before writing (see Pre-flight above).
• Never report internal refactors or chore-level commits to the user.
