Turn one day of git commits into a readable, grouped work summary. The goal is not to dump raw commit lines but to translate them into human-friendly task statements organized by workstream.
Language Detection
Detect the user's language from their request:
- Chinese or mixed Chinese input → output in Chinese (default)
- English input → output in English
- Keep identifiers, branch names, and commit hashes in their original form regardless of output language
Core Rules
- Default scope is today in the user's local timezone unless the user gives a specific date.
- Prefer git evidence over memory or assumptions.
- Group commits by workstream / theme, not by repository chronological order.
- Rewrite raw commit messages into concise action summaries.
- Do not inflate empty, noise-only, or clearly meaningless commits into standalone achievements.
Workflow
Step 1: Determine scope
Defaults:
- Date range: today
- Repository: current repository
Clarify only when necessary:
- Today vs a specific date
- Current repo vs multiple repos
- Whether the user wants only task summaries or task summaries + raw commit detail
Step 2: Collect commits
Pre-check: Verify the target directory is a git repository (git rev-parse --is-inside-work-tree). If git is not available or the directory is not a repo, report the error and stop — do not guess or fabricate commits.
Single repository:
git log --since="YYYY-MM-DD 00:00" --until="YYYY-MM-DD+1 00:00" --pretty=format:"%h%x09%s"
Multiple repositories (when the user provides a list of paths):
for repo in /path/to/repo-a /path/to/repo-b; do
echo "## $(basename $repo)"
git -C "$repo" log --since="YYYY-MM-DD 00:00" --until="YYYY-MM-DD+1 00:00" --pretty=format:"%h%x09%s"
echo ""
done
Shared repository: If the repo has multiple contributors and the user likely wants only their own commits, add --author="<user>" to the git log command. Detect the current user via git config user.name or git config user.email.
Edge cases:
- If no commits are found, state that clearly and stop.
- If the date range is ambiguous or unparseable, confirm with the user before defaulting.
- If a repo path does not exist or is not accessible, skip it with a warning and continue with remaining repos.
Step 3: Group into workstreams
Cluster related commits together:
- Same feature development
- Same bug fix
- Same config or toolchain adjustment
- Same documentation update
Do not create one summary line per commit when several commits are obviously part of the same workstream.
Step 4: Rewrite into action summaries
Good summary lines:
- Start with a clear action verb
- Describe the actual business or engineering result
- Omit noisy implementation trivia unless it matters
- Are understandable to someone scanning a daily report quickly
Chinese examples:
- Implemented persistence of filter conditions on the market page
- Fixed the issue where task polling did not refresh the overview in the terminal state
- Refactored the chart data mapping logic, reducing duplicate processing branches
- Added regression tests for the settings save flow
English examples:
- Implemented filter persistence on the market overview page
- Fixed task polling not refreshing overview when terminal state reached
- Refactored chart data mapping to reduce duplicate processing branches
Step 5: Output the report
Preferred structure:
- Date range
- Today's work summary
- Workstream / repo detail
- Raw commits appendix (optional)
Output Template

When Not to Use
- User wants a current-session wrap-up, not commit-based → use
session-wrap - User wants multi-project session aggregation → use
project-daily-summary - User has no git commits and needs working tree change summary
Quality Checklist
Before responding, verify:
- Date scope is explicit
- Summary is based on actual commits, not guesses
- Related commits are grouped into workstreams
- Summary lines are human-readable and action-oriented
- Empty or noise commits are not treated as major work items
- Output language matches the user's language
