media-library

Generate an interactive HTML page listing all saved social media posts, then open it in the browser.

Overview

Every card-generating skill saves populated HTML to docs/media/social/. This skill scans that directory, builds a filterable HTML page with clickable links to every card, and opens it in the browser.

---

Exit plan mode

ExitPlanMode is a deferred tool. Only call it if currently in plan mode — skip this step entirely when not in plan mode. When calling: use ToolSearch with select:ExitPlanMode first, then call ExitPlanMode silently.

Step 1 — Scan for saved posts

MEDIA_DIR="${PWD}/docs/media/social"
# Newest-first by the trailing -YYYY-MM-DD in each filename, NOT by mtime.
# (git checkout resets mtimes, so `ls -t` order is meaningless.)
MEDIA_FILES=$(find "$MEDIA_DIR" -maxdepth 1 -name "*.html" ! -name "index.html" 2>/dev/null \
  | sed -E 's/.*-([0-9]{4}-[0-9]{2}-[0-9]{2})\.html$/\1\t&/' \
  | sort -rk1,1 | cut -f2-)

If docs/media/social/ does not exist or contains no .html files, tell the user:

"No saved posts found in docs/media/social/. Run a sharing skill to generate your first post."

STOP.

Step 2 — Locate plugin assets

Find the templates/ directory to derive $PLUGIN_DIR:

find ~/.claude/plugins -path "*/social-media-tools/templates" -type d 2>/dev/null | head -1
find "$PWD" -path "*/social-media-tools/templates" -type d 2>/dev/null | head -1

Use the first non-empty result as TEMPLATES_DIR. Derive:

PLUGIN_DIR=$(dirname "$TEMPLATES_DIR")

If no directory is found: output "Templates not found. Install the plugin or load it with --plugin-dir." and STOP.

---

Step 3 — Build the HTML page

1. Read the gallery template from $PLUGIN_DIR/templates/gallery.html.

2. Build {{GALLERY_ENTRIES}} — for each card file (most recent first), parse the filename ({type}-{slug}-{YYYY-MM-DD}.html) and generate one card entry:

   <div class="gallery-card-wrap">
   <a class="gallery-card" href="{BASENAME}" data-type="{TYPE}" data-topic="{TOPIC}">
     <div class="thumb-container">
       <img src="{BASENAME_PNG}" alt="{TOPIC}" onerror="showFallback(this)">
       <span class="thumb-fallback" style="display:none">{TYPE}</span>
     </div>
     <div class="card-info">
       <div class="card-info-top">
         <span class="type-badge type-{TYPE}">{TYPE}</span>
         <span class="card-date">{DATE}</span>
       </div>
       <span class="card-topic">{TOPIC}</span>
       <span class="card-file">{BASENAME}</span>
     </div>
   </a>
   <button type="button" class="open-img-link" data-img="{BASENAME_PNG}" data-topic="{TOPIC}" aria-label="View image: {TOPIC}">View image</button>
   </div>
   

   Only include the .open-img-link button when a matching .png file exists alongside the .html card (test with -f "$MEDIA_DIR/${BASENAME_PNG}"). Omit the button element entirely for cards without a screenshot to avoid dead controls.

   Where:

   • {BASENAME} = filename without path (e.g., diff-add-copy-button-2026-05-27.html)
   • {BASENAME_PNG} = same with .png extension
   • {TYPE} = first segment of filename (e.g., diff, feature, blog)
   • {TOPIC} = middle segments with hyphens replaced by spaces, title-cased (e.g., "Add Copy Button")
   • {DATE} = last segment before .html (e.g., 2026-05-27)

3. Substitute variables in the template:

   • {{GALLERY_ENTRIES}} → the concatenated <a> blocks
   • {{CARD_COUNT}} → total number of cards
   • {{GENERATED_AT}} → current date and time (e.g., 2026-05-27 14:30)

4. Write the populated HTML to docs/media/social/index.html.

---

Step 4 — Open in browser

GALLERY_PATH=$(realpath "docs/media/social/index.html" 2>/dev/null || echo "${PWD}/docs/media/social/index.html")
open "$GALLERY_PATH" 2>/dev/null || xdg-open "$GALLERY_PATH" 2>/dev/null || true

Tell the user: "Media library generated at docs/media/social/index.html with {count} cards — opened in your browser. Click any card to view it."

---

Step 5 — Optional follow-up

If the user asks to view copy text from a specific card after seeing the library:

1. Read the chosen HTML file
2. Extract the text content of every <textarea class="post-copy-text">…</textarea>, noting each one's preceding <p class="copy-label"> label
3. Present each in its own fenced code block, headed by its platform label:

**[platform label]**
```
[extracted post copy text]
```

4. Tell the user which skill generated it (inferred from card type):
   • diff, feature, quote → share-code
   • blog → share-blog
   • video → share-video
   • snippet → share-github
   • project → share-project
   • session → share-session

Step 6 — Stop

STOP. Do not invoke any other skills or run git commands after delivering.
