Daily Releases

Create GitHub Releases with AI-categorized changelogs for every day that had commits. Uses the same pipeline as /create-merge-request-changelog — real AI analysis, not template substitution.

Automatic Invocation

When this skill is activated, immediately begin processing without asking the user. Parse any arguments from $ARGUMENTS:

--start-date YYYY-MM-DD   Only process days on or after this date
--end-date YYYY-MM-DD     Only process days on or before this date (default: today)
--branch BRANCH           Git branch (default: origin/main)
--dry-run                 Preview without creating releases

Process

Step 1: List days to process

uv run scripts/list_daily_ranges.py [--branch BRANCH] [--start-date ...] [--end-date ...]

This outputs a JSON array. Each entry has:

{
  "date": "2026-02-21",
  "tag": "v2026.02.21",
  "base_ref": "<parent-commit-hash>",
  "head_ref": "<last-commit-hash-of-day>",
  "commit_count": 12,
  "release_exists": true,
  "needs_update": false
}

Skip entries where release_exists: true and needs_update: false — those are up to date.

For --dry-run, print the list and stop.

Step 2: For each day that needs a release

Work through days chronologically. For each day:

2a. Extract git data

uv run ../create-merge-request-changelog/scripts/analyze_git_changes.py \
  <base_ref> <head_ref> /tmp/daily-releases/<date>/

This writes to /tmp/daily-releases/<date>/:

• commits_oneline.txt — one-line commit list
• commits_detailed.txt — full commit messages with metadata
• changes.diff — unified diff
• changes_stat.txt — diffstat summary
• changed_files.txt — file list with A/M/D status
• changes_numstat.txt — per-file line counts
• summary.json — machine-readable stats

2b. AI analysis

Read the extracted data and apply the primary analysis prompt from:

../create-merge-request-changelog/references/analysis_prompts.md

Use the Primary Analysis Prompt section with the day's data substituted in:

• {commit_details} → contents of commits_detailed.txt
• {changes_diff} → contents of changes.diff (truncate to ~4000 chars if very large; use changes_stat.txt summary instead)
• {changed_files} → contents of changed_files.txt
• {commit_count}, {files_changed}, {lines_added}, {lines_deleted} → from summary.json

Produce the structured JSON analysis output defined in the prompt's <output_format> section.

Also generate a title using the Title Generation Prompt:

Daily Release - <date>

Save the complete analysis JSON to /tmp/daily-releases/<date>/analysis.json.

2c. Format into release notes

uv run ../create-merge-request-changelog/scripts/format_mr_description.py \
  /tmp/daily-releases/<date>/analysis.json \
  --no-preview \
  --output /tmp/daily-releases/<date>/description.md

2d. Publish the release

uv run scripts/publish_daily_release.py \
  --date <date> \
  --tag <tag> \
  --head-ref <head_ref> \
  --notes-file /tmp/daily-releases/<date>/description.md

Add --keep-existing-tag=false if updating a release that already has the correct tag commit.

Step 3: Report

After processing all days, print a summary:

Processed N days:
  - Created: X new releases
  - Updated: Y existing releases
  - Skipped: Z already up to date
