podcast

/pika:podcast

4 acts × 15s each = 60s. Host A always LEFT, Host B always RIGHT. Accepts a URL or a free-form topic / brief.

Parameters

Param	Default	Notes
input	required	URL to review or free-form topic / brief (e.g. "I and Elon Musk talk about Mars")
bg_img	auto-generated	Podcast studio background
host_a_img	auto-generated	Host A portrait — see Real-person handling below
host_b_img	auto-generated	Host B portrait — see Real-person handling below
voice_a	876341503281471517	Kling preset or cloned voice ID for Host A
voice_b	829837252279803904	Kling preset or cloned voice ID for Host B
use_avatar	off	Clone user's identity voice as Host A via clone_voice
aspect_ratio	16:9	Output aspect ratio

Defaults — fire fast, no mid-flow confirmation

• Use the param-table defaults silently for voices. voice_a defaults to the Kling preset 876341503281471517 and voice_b to 829837252279803904. Do not ask "which voice?" or "should I clone yours?" before firing — only honor explicit overrides (voice_a=, voice_b=, use_avatar).
• Auto-generate any missing host portraits silently (Step 1's archetype prompts). Do not ask "should I generate a host image?" — just generate.
• No "type yes to proceed" gates. Submit → render the 4 acts → return URL. Account credit balance + provider failover are the canonical guardrails. The --yes flag is accepted as a no-op for backward compatibility.
• Topic-mode personas (Step 3) — when the user names a real public figure, follow Step 4 (Real-person handling) silently: archetype portrait by default, no auto-generated photographic likeness, no question to the user about likeness rights.

Local images on Claude Desktop

Claude Desktop can't pass inline-pasted images to MCP tools yet (Anthropic-side limitation). If the user pastes a photo inline, or mentions a local file they want as host_a_img / host_b_img, pause Step 1 and kindly send them this — something like:

Heads up — pasted images don't reach MCP tools on Claude Desktop yet (Anthropic limitation). Two easy options for your photo:

• Paste a URL if it's already hosted (Imgur, S3, your site) — fastest
• Attach the image file so I can upload it before generation.

When a local file arrives, convert it to a public URL with upload_asset and use the returned public_url as the parameter before Step 1. Already-hosted https://... URLs work as-is and skip this entirely.

If the user names a real public figure without attaching anything, do NOT auto-generate their likeness — Step 4 (Real-person handling) uses an archetype portrait instead.

Steps

0. Resolve input (empty-args menu)

Strip flags (--yes, --no-captions, etc.) and key=value parameters from $ARGUMENTS. If what remains is empty or whitespace-only, print this menu verbatim as your full response, then stop and wait for the user's next message — do NOT call any tool, do NOT proceed to Step 1, do NOT invent a topic or URL. If the stripped input is non-empty (a URL or any prose), skip this step silently and proceed to Step 1.

What would you like a podcast about? I can take any of:

• A website URL (product page, docs site, launch page) — e.g. https://pika.art
• A GitHub repo — e.g. https://github.com/anthropics/claude-code
• A blog post / article URL — e.g. a recent piece you'd like discussed
• A free-form topic or brief — e.g. "I and Elon Musk talk about Mars" or "two scientists debate AGI"

Reply with your choice and I'll generate a 1-minute two-host podcast video (4 acts × ~15s).

Tip: you don't need to type /pika:podcast — just say things like "make a podcast about ", "podcast review of ", or "I and talk about " and I'll fire this skill automatically.

When the user replies, treat their reply as the resolved input (URL or topic) and proceed to Step 1. Do not re-prompt.

1. Generate missing assets (parallel)

Generate only what's not provided. Default archetype prompts:

• bg_img — modern podcast studio, two chairs, warm lighting, no people, 16:9
• host_a_img — enthusiastic host, studio portrait, left-side framing, 1:1
• host_b_img — pragmatic skeptic host, studio portrait, right-side framing, 1:1

If the input mentions specific personas (Step 3), tune the archetype to match the persona vibe — see Real-person handling below.

2. Resolve voice IDs (only if use_avatar is set)

1. Call identity_voice_info → { voice_id, platform, sample_url }
2. If sample_url is present: call clone_voice(voice_url=sample_url, voice_name="host_a_voice") → set voice_a to the returned Kling voice ID

3. Parse input mode — URL vs topic

Strip flags (--yes, --no-captions, etc.) and key=value parameters from $ARGUMENTS. Inspect what remains.

URL mode — input contains a https?:// URL:

• Call capture_website on the URL.
• Extract: product name, value prop, 2–3 specific features or facts, pricing, one jokeable detail.
• Use these as the script's factual anchors.

Topic mode — input is free-form prose (no URL):

• Treat the whole input as the brief. Parse for:
  • Subject — what the conversation is about
  • Hosts — explicit if mentioned ("I and Elon Musk", "two scientists", "Joe and Sarah"); otherwise use defaults (enthusiastic host + skeptic host)
  • Angle — debate / interview / explainer / casual
  • Concrete facts — any specific claims, numbers, dates, quotes the user gave
• If no concrete facts are given, use 2–3 clearly framed observations or hypotheses to anchor jokes and the "wait, actually..." pivot. Do not present invented claims as facts; if factual accuracy matters for the topic, ask for a source or URL.
• If the user says "I and X" or "me and X", Host A = the user (use use_avatar flow if not already, or default avatar) and Host B = X.

4. Real-person handling (topic mode only)

If the parsed input names a specific real public figure as a host (e.g. "Elon Musk", "Taylor Swift", "Joe Rogan"):

• Default behavior: do NOT auto-generate that person's photographic likeness. Generate an archetype portrait matching the persona vibe — e.g. "tech-billionaire-energy CEO at a podcast desk" for an Elon-style host, "pop-star aesthetic" for a Taylor-style host. Clearly inspired-by, not impersonation.
• Override: if the user explicitly provides host_a_img=<url> or host_b_img=<url>, use the provided image as-is. The user takes responsibility for likeness rights.
• Voices: same logic — default to a generic Kling preset; only use a cloned voice when the user provides one (voice_a= / voice_b=) or invokes use_avatar (which clones the user's own voice for Host A).
• Script tone: the dialogue can riff on the named persona's known public positions or vibe (e.g. Mars enthusiasm for Elon-style) — public-record opinions are fair game. Do NOT put specific defamatory, off-character, or fabricated-private-life statements in their mouth.

This guardrail keeps the skill creative ("I want a podcast where I argue with a tech CEO about Mars") without auto-generating deepfakes of named real people.

5. Write script

Write 4 acts × 2 lines (HOST_A / HOST_B). Each line ~10–12s of spoken dialogue.

Required (Matan rules — apply to both URL and topic modes):

• One specific joke tied to a concrete detail (scraped fact in URL mode; topic-derived claim in topic mode)
• One "wait, actually..." skeptic-flip moment
• At least one mid-sentence interruption
• Natural filler: "okay so", "wait", "right?", "i mean", "honestly"
• Real reactions, not generic praise
• Reference at least one actual feature name, price, claim, or quote
• Natural ending — no forced "bye!"

Acts: Hook → Feature deep-dive → The Turn → Verdict (In topic mode the analogue: Hook → Substance → The Pivot → Verdict.)

6. Generate video acts (subagent, sequential)

Delegate to a subagent with all resolved assets and the script. The subagent runs acts 1→2→3→4 sequentially — do NOT parallelize.

Each act: one generate_reference_video call (kling-v3-omni, duration=15, sound=true). Pass reference_images=[bg_img, host_a_img, host_b_img] and voice_ids=[voice_a, voice_b]. Optional knobs (added by pika-mcp-server BACK-339, 2026-05-10): quality_mode: "pro" for higher-fidelity kling output (longer wall-clock; reserve for high-stakes renders), and kling_model to pin a specific kling family member if you need reproducibility across runs. Three shots:

• Wide 5s: both hosts, no voice token
• MCU-A 5s: <<<voice_1>>> '<HOST_A line>'
• MCU-B 5s: <<<voice_2>>> '<HOST_B line>'

Emotional beats per act:

• Act 1: A excited, B skeptical
• Act 2: A gesturing/explaining, B questioning
• Act 3: A firm, B surprised and reconsidering
• Act 4: A satisfied, B conceding

After act 4, subagent calls edit_concat([act1, act2, act3, act4]) and returns the final video URL.

7. Output

Return the final video URL and a one-sentence verdict. Do not call add_captions — Whisper auto-transcription is unreliable on the domain-specific terms typical of podcast dialogue (product names, persona names, technical jargon). Native Kling Omni audio is the deliverable.

---

Rules:

• voice_ids must be valid Kling voice IDs — never use name-style strings like Calm_Man
• Host A always LEFT (<<<image_2>>>), Host B always RIGHT (<<<image_3>>>) — never swapped

Load-bearing phrases

These anchors keep the podcast output coherent across URL and topic modes:

Phrase	Where	Why load-bearing
Host A always LEFT, Host B always RIGHT	Layout and shot prompts	Prevents host identity swapping across the four separate act renders.
4 acts × 15s each	Overall structure	Keeps the concat predictable and avoids uneven act pacing.
Hook → Feature deep-dive → The Turn → Verdict	Script structure	Gives the episode a conversational arc instead of four disconnected reactions.
wait, actually... skeptic-flip moment	Script requirements	Creates the pivot that makes the podcast feel like a real exchange.
Do not call add_captions	Output rule	Avoids low-quality burned captions on fast two-host dialogue with names and jargon.

Engine choice: Kling v3-omni for native two-host dialogue

Use Kling v3-omni for the four acts because it supports native dialogue with two reference hosts and voice tokens in a single shot plan. The tradeoff is that acts run sequentially for consistency and can take longer than pure edit/composite flows. Do not add a separate caption or music layer by default; the value of this skill is the native spoken exchange.

Runtime expectations

Typical wall-clock is 8-18 minutes:

Step	Wall clock	Notes
Missing asset generation	30-90s	Skipped for provided background/host refs
URL/topic parse + script	1-3 min	URL mode depends on page fetch quality
Four Kling acts	6-14 min	Runs sequentially to reduce host/voice drift
Concat + return	30-90s	Final URL only; captions skipped by default
