lylll9436/paper-polish-workflow-skill/ppw-update

Purpose

This Skill syncs local .claude/skills/ and references/ from the upstream GitHub repository Lylll9436/Paper-Polish-Workflow-skill. It downloads the latest SKILL.md files and reference documents, compares them with local versions, and updates any changed files.

Trigger

Activates when the user asks to:

• Update or sync skills from the remote repo
• 更新或同步技能包

Example invocations:

• "update skills"
• "sync skills from GitHub"
• "更新技能"

Modes

Default mode: direct

Workflow

Step 0: Workflow Memory Check

• Read .planning/workflow-memory.json. If file missing or empty, skip to Step 1.
• Check if the last 1-2 log entries form a recognized pattern with ppw:update that has appeared >= threshold times in the log. See skill-conventions.md > Workflow Memory > Pattern Detection for the full algorithm.
• If a pattern is found, present recommendation via AskUserQuestion:
• Question: "检测到常用流程：[pattern]（已出现 N 次）。是否直接以 direct 模式运行 ppw:update？"
• Options: "Yes, proceed" / "No, continue normally"
• If user accepts: set mode to direct, skip Ask Strategy questions.
• If user declines or AskUserQuestion unavailable: continue in normal mode.

Step 1: Pre-flight Check

• Verify gh CLI is available and authenticated: gh auth status
• Verify the upstream repo is accessible: gh api repos/Lylll9436/Paper-Polish-Workflow-skill --jq '.full_name'
• If either check fails, report the error and stop.
• Record workflow: Append {"skill": "ppw:update", "ts": "<ISO timestamp>"} to .planning/workflow-memory.json. Create file as [] if missing. Drop oldest entry if log length >= 50.

Step 2: Fetch Remote File Index

• List all skill directories from the remote repo:

``bash gh api repos/Lylll9436/Paper-Polish-Workflow-skill/contents/.claude/skills --jq '.[].name' ``

• List all reference files from the remote repo:

``bash gh api repos/Lylll9436/Paper-Polish-Workflow-skill/contents/references --jq '.[] | .name + " " + .type' ``

• For reference subdirectories (type=dir), also list their contents recursively.

Step 3: Compare and Update Skills

For each remote skill directory:

1. Fetch the remote SKILL.md content:

``bash gh api repos/Lylll9436/Paper-Polish-Workflow-skill/contents/.claude/skills/{skill-name}/SKILL.md --jq '.content' | base64 -d ``

1. Read the local .claude/skills/{skill-name}/SKILL.md if it exists.
2. Compare the two:

• If local file does not exist → NEW skill, create directory and write file.
• If content differs → UPDATED, overwrite local file.
• If content is identical → UNCHANGED, skip.

1. Track results for the final report.

In `interactive` mode: Before applying each update, show a summary of changes and ask for confirmation.

Step 4: Compare and Update References

For each remote reference file:

1. Fetch the remote file content via gh api with base64 decode.
2. Read the local references/{filename} if it exists.
3. Compare and apply the same NEW/UPDATED/UNCHANGED logic as Step 3.
4. For subdirectories (e.g., references/journals/, references/expression-patterns/), recurse into each file.

Step 5: Output Report

Present a summary table:

## Skills Update Report
 
| Skill | Status |
|-------|--------|
| polish-skill | ✓ Updated |
| de-ai-skill | - Unchanged |
| new-skill | + New |
 
## References Update Report
 
| File | Status |
|------|--------|
| expression-patterns.md | ✓ Updated |
| skill-conventions.md | - Unchanged |
 
**Summary:** {updated_count} updated, {new_count} new, {unchanged_count} unchanged
