Decision brief

What it does—and where it fits

Analyze the differences between the current branch and origin/main, and summarize the current work progress.

Best for

Not for

Tasks that require unconfirmed production actions or broad system permissions.
Environments where the pinned source and install steps cannot be inspected.

Installation

Inspect first. Install second.

The source command is displayed only when detected. A safe inspection prompt is always available so your agent can explain every action before execution.

Safe inspection promptEditorial

Inspect the Agent Skill "diff-analyze" from https://github.com/dyoshikawa/rulesync/blob/310b711fbe8cffc14debb276ade8a384c2b89083/.rulesync/skills/diff-analyze/SKILL.md at commit 310b711fbe8cffc14debb276ade8a384c2b89083. List every install step, command, network request, credential, file read/write, external action, and rollback step. Explain whether it fits my task. Do not install or execute anything until I approve.

Diff Analyze

Analyze the differences between the current branch and origin/main, and summarize the current work progress.

Step 1: Refresh Main Branch

Fetch the latest main branch state:

git fetch origin main

Step 2: Inspect the Diff

Get the differences between the current branch and main:

git diff origin/main...HEAD

Step 3: Inspect Commit History

Get the commit history of the current branch since it diverged from main:

git log origin/main..HEAD --oneline

Step 4: Summarize the Work

Based on the diff and commit history, summarize:

The main purpose of the current changes
The notable files or areas affected
The current implementation progress
Any obvious risks, gaps, or follow-up work

Keep the summary concise and practical.

dask

Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.
