# Clip Social Media Upload Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Generate social media descriptions/hashtags for podcast clips and upload them to Instagram Reels + YouTube Shorts via Postiz API.

**Architecture:** Two changes — (1) extend `make_clips.py` to add a second LLM call that generates descriptions + hashtags, saved as `clips-metadata.json`, (2) new `upload_clips.py` script that reads that metadata and pushes clips through the self-hosted Postiz instance at `social.lukeattheroost.com`.

**Tech Stack:** Python, OpenRouter API (Claude Sonnet), Postiz REST API, requests library (already installed)

---

### Task 1: Add `generate_social_metadata()` to `make_clips.py`

**Files:**
- Modify: `make_clips.py:231-312` (after `select_clips_with_llm`)

**Step 1: Add the function after `select_clips_with_llm`**

Add this function at line ~314 (after `select_clips_with_llm` returns):

```python
def generate_social_metadata(clips: list[dict], labeled_transcript: str,
                              episode_number: int | None) -> list[dict]:
    """Generate social media descriptions and hashtags for each clip."""
    if not OPENROUTER_API_KEY:
        print("Error: OPENROUTER_API_KEY not set in .env")
        sys.exit(1)

    clips_summary = "\n".join(
        f'{i+1}. "{c["title"]}" — {c["caption_text"]}'
        for i, c in enumerate(clips)
    )

    episode_context = f"This is Episode {episode_number} of " if episode_number else "This is an episode of "

    prompt = f"""{episode_context}the "Luke at the Roost" podcast — a late-night call-in show where AI-generated callers share stories, confessions, and hot takes with host Luke.

Here are {len(clips)} clips selected from this episode:

{clips_summary}

For each clip, generate:
1. description: A short, engaging description for social media (1-2 sentences, hook the viewer, conversational tone). Do NOT include hashtags in the description.
2. hashtags: An array of 5-8 hashtags. Always include #lukeattheroost and #podcast. Add topic-relevant and trending-style tags.

Respond with ONLY a JSON array matching the clip order:
[{{"description": "...", "hashtags": ["#tag1", "#tag2", ...]}}]"""

    response = requests.post(
        "https://openrouter.ai/api/v1/chat/completions",
        headers={
            "Authorization": f"Bearer {OPENROUTER_API_KEY}",
            "Content-Type": "application/json",
        },
        json={
            "model": "anthropic/claude-sonnet-4-5",
            "messages": [{"role": "user", "content": prompt}],
            "max_tokens": 2048,
            "temperature": 0.7,
        },
    )

    if response.status_code != 200:
        print(f"Error from OpenRouter: {response.text}")
        return clips

    content = response.json()["choices"][0]["message"]["content"].strip()
    if content.startswith("```"):
        content = re.sub(r"^```(?:json)?\n?", "", content)
        content = re.sub(r"\n?```$", "", content)

    try:
        metadata = json.loads(content)
    except json.JSONDecodeError as e:
        print(f"Error parsing social metadata: {e}")
        return clips

    for i, clip in enumerate(clips):
        if i < len(metadata):
            clip["description"] = metadata[i].get("description", "")
            clip["hashtags"] = metadata[i].get("hashtags", [])

    return clips
```

**Step 2: Run existing tests to verify no breakage**

Run: `pytest tests/ -v`
Expected: All existing tests pass (this is a new function, no side effects yet)

**Step 3: Commit**

```bash
git add make_clips.py
git commit -m "Add generate_social_metadata() for clip descriptions and hashtags"
```

---

### Task 2: Integrate metadata generation + JSON save into `main()`

**Files:**
- Modify: `make_clips.py:1082-1289` (inside `main()`)

**Step 1: Add metadata generation call and JSON save**

After the LLM clip selection step (~line 1196, after the clip summary print loop), add:

```python
    # Step N: Generate social media metadata
    print(f"\n[{extract_step - 1}/{step_total}] Generating social media descriptions...")
    clips = generate_social_metadata(clips, labeled_transcript, episode_number)
    for i, clip in enumerate(clips):
        if "description" in clip:
            print(f"    Clip {i+1}: {clip['description'][:80]}...")
            print(f"           {' '.join(clip.get('hashtags', []))}")
```

Note: This needs to be inserted BEFORE the audio extraction step, and the step numbering needs to be adjusted (total steps goes from 5/6 to 6/7).

At the end of `main()`, before the summary print, save the metadata JSON:

```python
    # Save clips metadata for social upload
    metadata_path = output_dir / "clips-metadata.json"
    metadata = []
    for i, clip in enumerate(clips):
        slug = slugify(clip["title"])
        metadata.append({
            "title": clip["title"],
            "clip_file": f"clip-{i+1}-{slug}.mp4",
            "audio_file": f"clip-{i+1}-{slug}.mp3",
            "caption_text": clip.get("caption_text", ""),
            "description": clip.get("description", ""),
            "hashtags": clip.get("hashtags", []),
            "start_time": clip["start_time"],
            "end_time": clip["end_time"],
            "duration": round(clip["end_time"] - clip["start_time"], 1),
            "episode_number": episode_number,
        })
    with open(metadata_path, "w") as f:
        json.dump(metadata, f, indent=2)
    print(f"\nSocial metadata: {metadata_path}")
```

**Step 2: Adjust step numbering**

The pipeline steps need to account for the new metadata step. Update `step_total` calculation:

```python
    step_total = (7 if two_pass else 6)
```

And shift the extract/video step numbers up by 1.

**Step 3: Test manually**

Run: `python make_clips.py --help`
Expected: No import errors, help displays normally

**Step 4: Commit**

```bash
git add make_clips.py
git commit -m "Save clips-metadata.json with social descriptions and hashtags"
```

---

### Task 3: Create `upload_clips.py` — core structure and Postiz API helpers

**Files:**
- Create: `upload_clips.py`

**Step 1: Write the script**

```python
#!/usr/bin/env python3
"""Upload podcast clips to Instagram Reels and YouTube Shorts via Postiz.

Usage:
    python upload_clips.py clips/episode-12/

if __name__ == "__main__":
    main()
```

**Step 2: Add `POSTIZ_API_KEY` and `POSTIZ_URL` to `.env`**

Add to `.env`:
```
POSTIZ_API_KEY=your-postiz-api-key-here
POSTIZ_URL=https://social.lukeattheroost.com
```

Get your API key from Postiz Settings page.

**Step 3: Test the script loads**

Run: `python upload_clips.py --help`
Expected: Help text displays with all flags

**Step 4: Commit**

```bash
git add upload_clips.py
git commit -m "Add upload_clips.py for posting clips to Instagram/YouTube via Postiz"
```

---

### Task 4: Test with real Postiz instance

**Step 1: Get Postiz API key**

Go to `https://social.lukeattheroost.com` → Settings → API Keys → Generate key. Add to `.env` as `POSTIZ_API_KEY`.

**Step 2: Verify integrations endpoint**

Run: `python -c "from upload_clips import *; print(json.dumps(fetch_integrations(), indent=2))"`

This confirms the API key works and shows connected Instagram/YouTube accounts. Note the integration IDs and provider identifiers — if `find_integration()` doesn't match correctly, adjust the provider string matching.

**Step 3: Dry-run with existing clips**

Run: `python upload_clips.py clips/episode-12/ --dry-run`
Expected: Shows clip summary, "Dry run — nothing uploaded."

**Step 4: Upload a single test clip**

Run: `python upload_clips.py clips/episode-12/ --clip 1 --instagram-only`

Check Postiz dashboard and Instagram to verify it posted as a Reel.

**Step 5: Commit .env update (do NOT commit the key itself)**

The `.env` is gitignored so no action needed. Just ensure the key names are documented in CLAUDE.md if desired.
