How to read this report

Each claim is labeled with one of these tags:

Tag	Meaning
[Fact]	Stated on an official provider page. The source is linked inline and again in the final list.
[Inference]	My reasoning from the official facts, such as why one option ranks above another.
[Uncertain]	I could not fully verify it, or it is likely to change soon.

Currency. Providers publish prices in USD. GBP figures are my conversions using the European Central Bank reference rates for 1 Oct 2026 (EUR 1 = USD 1.1298 = GBP 0.85373), which gives USD 1 ≈ GBP 0.7556 (ECB daily rates). None of the four providers publish a GBP price list on the pages I checked. Your card statement may differ because of your bank's FX margin. Taxes such as UK VAT may be added (for example, ElevenLabs says "Prices exclude all taxes, levies and duties").

Why everything here is an API. A worker agent cannot sign in to a consumer website for you. It needs a developer API that it can call with a key. Every recommendation below is the provider's developer/API product, not its consumer app subscription. Consumer plans such as ChatGPT Plus, Gemini app plans, the Runway web app or the ElevenLabs web Studio generally do not give an agent API access. ElevenLabs is the exception: its subscription plans also cover API usage.

Summary: the two picks per skill

Skill	Pick 1	Pick 2
create video	Google Gemini API: Gemini Omni Flash / Veo 3.1 (Multi)	Runway API (Runway Dev): Gen-4.5, Aleph 2.0, plus hosted Seedance/Veo (Multi)
create image	OpenAI API: GPT Image 2.5 (Sunburst / Flare) (Multi)	Google Gemini API: Nano Banana Pro (gemini-3-pro-image) (Multi)
create audio	ElevenLabs API: voice, music, sound effects (Audio)	Google Gemini API: Gemini 3.8 Flash TTS + Lyria 3.5 music (Multi)

Three of the four providers produce more than one kind of media, so they are described once in the Multi section. ElevenLabs is the only audio-only pick.

Simplest setup for beginners [Inference]. One Google Gemini API key covers all three skills at premium quality. Add ElevenLabs if the job needs top-end voice work, and add Runway if it needs professional video delivery formats (ProRes/HDR).

Important time-sensitive finding [Fact]. OpenAI's Sora 2 video models and Videos API were shut down on 24 September 2026. OpenAI states that "no one-to-one replacement API is available" (OpenAI video guide, OpenAI deprecations). Older guides that recommend Sora for agent video work are now out of date. OpenAI is therefore listed here for image and audio only.

1. MULTI (tools covering more than one media type)

1.1 Google Gemini API (video + image + audio + music)

Why it was chosen [Inference, based on the facts below]

• It is the only single account and key that covers all three skills with current flagship models: video (Gemini Omni Flash, Veo 3.1), image (Nano Banana Pro / Nano Banana 2), speech (Gemini 3.8 Flash TTS) and music (Lyria 3.5).
• [Fact] Google calls Gemini Omni Flash its default video model, citing "superior video coherence, multi-input reasoning (supporting text, images, audio, and video inputs simultaneously), character consistency, factual accuracy, and multi-turn conversational editing". It also says to use Veo 3.1 for "scene extension, last-frame control" (Gemini video overview).
• [Fact] Veo 3.1 generates video with native audio and offers 4K output on the Standard and Fast tiers (pricing).
• [Fact] Google publishes official coding-agent support: a Gemini Docs MCP server and installable "Gemini API Skills". It names Claude Code explicitly (coding agent setup). This helps an agent use the current API correctly.
• [Fact] On the free tier, the pricing page marks content as "Used to improve our products: Yes". On the paid tier it says "No" (pricing). For premium/client work, use the paid tier.

Costs [Fact: Gemini API pricing page, 1 Oct 2026]

Video (charged per second of generated video; audio included by default; no free tier)

Model (ID)	USD	GBP (≈)
Gemini Omni Flash (gemini-omni-1.1-flash), 720p	≈ $0.10 / sec (token-billed: $17.50 per 1M video output tokens, 5,792 tokens/sec)	≈ £0.076 / sec
Veo 3.1 Standard (veo-3.1-generate-preview), 720p/1080p	$0.40 / sec	£0.30 / sec
Veo 3.1 Standard, 4K	$0.60 / sec	£0.45 / sec
Veo 3.1 Fast (veo-3.1-fast-generate-preview), 720p / 1080p / 4K	$0.10 / $0.12 / $0.30 per sec	£0.076 / £0.091 / £0.23 per sec
Veo 3.1 Lite (veo-3.1-lite-generate-preview), 720p / 1080p	$0.05 / $0.08 per sec	£0.038 / £0.060 per sec

Worked example [Inference]: an 8-second 1080p clip on Veo 3.1 Standard costs $3.20 (≈ £2.42). On Omni Flash at 720p it is about $0.80 (≈ £0.60). Agents often need several attempts per usable clip, so budget a multiple of these figures.

Image

Model (ID)	USD per image	GBP (≈)
Nano Banana Pro (gemini-3-pro-image), 1K/2K	$0.134	£0.10
Nano Banana Pro, 4K	$0.24	£0.18
Nano Banana 2 (gemini-3.1-flash-image), 1K / 2K / 4K	$0.067 / $0.101 / $0.151	£0.051 / £0.076 / £0.114

Batch mode is half price for both image models.

Audio

Model (ID)	USD	GBP (≈)
Gemini 3.8 Flash TTS (gemini-3.8-flash-tts)	Through 31 Dec 2026: ≈ $0.00225 per 10 sec of audio (≈ $0.0135/min). From 1 Jan 2027: ≈ $0.0045 per 10 sec (≈ $0.027/min)	≈ £0.010/min → ≈ £0.020/min
Lyria 3.5 music (lyria-3.5)	$0.08 per full song	£0.060 per song
Lyria 3 Clip Preview (lyria-3-clip-preview)	$0.04 per 30-second clip	£0.030

Requirements

1. Google account and a Google AI Studio project [Fact].
2. Gemini API key. Get it from the AI Studio API keys page. The SDKs read it from the GEMINI_API_KEY (or GOOGLE_API_KEY) environment variable [Fact] (API keys).
3. Paid tier / billing [Fact]. Veo, Omni Flash, Nano Banana Pro and Lyria have no free tier. To upgrade you link a Cloud billing account and usually prepay at least $5 (≈ £3.78). Requests are served only while the prepaid balance is positive. Tier 1 starts with a $250 (≈ £189) billing cap, which rises with spend and account age (billing).
4. SDK: pip install google-genai (Python) or npm install @google/genai (Node) [Fact] (libraries).

How to obtain them

• Go to Google AI Studio, sign in, open Get API key, and create a key in a project.
• On that page (or the Projects page), click Set up billing, add a billing account and prepay credit (billing).

Other useful info

• [Fact] Google's coding-agent page recommends npx add-mcp "https://gemini-api-docs-mcp.dev". This is a documentation MCP: it helps the agent write correct code but does not generate media itself. It also recommends npx skills add google-gemini/gemini-skills --skill gemini-api-dev --global (coding agent setup).
• [Fact] Several models are still labeled "preview" (for example, the Veo 3.1 IDs). Preview models can change or be retired.
• [Fact] For Veo, "You will only be charged if your video is successfully generated."

---

1.2 Runway API, "Runway Dev" (video, plus image and audio)

Why it was chosen [Inference, based on the facts below]

• It is built for professional video delivery. [Fact] Gen-4.5 and Aleph 2.0 can output ProRes, PNG sequences, 10-bit SDR, and true HDR (HDR10, HLG, 12-bit masters, ACEScg EXR). It also offers video upscaling, frame-rate conversion and SDR-to-HDR (models). These are deliverable formats a premium client may ask for, and the Gemini API does not list them.
• [Fact] One Runway key reaches many leading third-party models: Seedance 2.5/2.0, Veo 3.1, Gemini Omni Flash, MiniMax H3, WAN 3.0 and Grok Imagine for video; GPT Image 2.5, Nano Banana Pro/2 and Seedream 5 for image; ElevenLabs v4/v3 for audio. It also has a Model Router that "automatically route[s] each request to the best available model… No additional cost" (models). For a beginner this means one bill and one key for many top models.
• [Fact] Aleph 2.0 edits existing video (video + text/image in, video out). Act-Two does performance/character animation.

Costs [Fact: Runway pricing page]

Credits cost $0.01 each (≈ £0.0076), and sales tax may apply. The minimum first payment is $10 (≈ £7.56) (setup, pricing).

Model (ID)	Credits	USD	GBP (≈)
Gen-4.5 (gen4.5)	12 / sec	$0.12 / sec	£0.091 / sec
Aleph 2.0 (aleph2) video editing	28 / sec (min 56 per job)	$0.28 / sec	£0.21 / sec
Seedance 2.5 (seedance2_5), 1080p	68 / sec output (+34 / sec of input video; min 80)	$0.68 / sec	£0.51 / sec
Veo 3.1 with audio (veo3.1)	40 / sec	$0.40 / sec	£0.30 / sec
Gemini Omni Flash 1.1 (gemini_omni_flash_1.1), 1080p / 4K	15 / 30 per sec	$0.15 / $0.30 per sec	£0.11 / £0.23 per sec
ProRes / PNG-sequence surcharge	+5 / sec	+$0.05 / sec	+£0.038 / sec
HDR / 10-bit surcharge	+20 / sec (+40 above ~4K)	+$0.20 / sec (+$0.40)	+£0.15 (+£0.30)
GPT Image 2.5 (gpt_image_2_5_sunburst / _flare), high, 1K/2K	16 per image	$0.16	£0.12
Nano Banana Pro (gemini_image3_pro), 1K/2K / 4K	20 / 40 per image	$0.20 / $0.40	£0.15 / £0.30
ElevenLabs v3 via Runway (eleven_v3)	1 per 50 characters	$0.20 per 1K characters	£0.15

Worked example [Inference]: a 10-second Gen-4.5 clip is 120 credits, or $1.20 (≈ £0.91). Delivering it as HDR10 adds 200 credits (+$2.00 ≈ £1.51).

Note [Inference]: reselling through Runway can cost more than going direct. ElevenLabs v3 is $0.20 per 1K characters through Runway versus $0.08 direct, and Nano Banana Pro is $0.20 versus $0.134 direct. Veo 3.1 with audio is the same price ($0.40/sec) either way.

Requirements

1. Runway Developer Portal account (separate from the Runway web app) [Fact].
2. Project + API key. Keys are project-scoped and shown only once. The SDK reads the RUNWAYML_API_SECRET environment variable [Fact] (setup).
3. Credits: at least $10 prepaid [Fact].
4. SDK: Python package runwayml; Node package @runwayml/sdk [Fact] (SDKs).

How to obtain them

Sign up at dev.runwayml.com. Create a project, open API Keys, create a key and copy it immediately. Then open Billing and add credits (setup).

Other useful info

• [Fact] Runway provides a "Runway Dev" MCP server at https://dev.runwayml.com/mcp with official commands for both clients:

  • Claude Code: claude mcp add --transport http --scope user runway-dev-mcp https://dev.runwayml.com/mcp
  • Codex: codex mcp add runway-dev-mcp --url https://dev.runwayml.com/mcp, then codex mcp login runway-dev-mcp --scopes openid,profile,email,mcp:read,mcp:write

  This MCP is for managing your account, tasks and docs, not for generating media. Runway says a separate "generation MCP at mcp.runwayml.com… creates media in chat" (Runway MCP page). Runway also says to complete OAuth yourself in a browser and not to let the agent automate sign-in.

• [Uncertain] I did not verify whether mcp.runwayml.com bills against API credits or a Runway web-app plan. The reliable route for a worker is the API key + SDK (see the setup steps in section 3).

• [Fact] Runway has a "Go-live checklist" and usage tiers that affect concurrency. Check them before taking high-volume jobs.

---

1.3 OpenAI API (image + audio; no video since 24 Sep 2026)

Why it was chosen (for image) [Inference, based on the facts below]

• [Fact] OpenAI's current image models are gpt-image-2.5-sunburst ("for workflows where editing precision matters most") and gpt-image-2.5-flare ("fast, high-quality everyday image generation"). Both add xhigh and max quality settings and support sizes up to 3840 px (4K) and transparent backgrounds (image generation guide).
• They have strong prompt-following and image-editing endpoints (generate and edit, reference images, input_fidelity), which suit premium jobs that need iteration on a brief [Fact: features; Inference: suitability].
• Codex users will already have an OpenAI platform account if they use API billing [Inference].

Costs [Fact: OpenAI pricing + image guide]

• GPT Image 2.5 (both variants) is billed per token: $30 per 1M image-output tokens, $8 per 1M image-input tokens and $5 per 1M text-input tokens. In GBP: ≈ £22.67 / £6.05 / £3.78. Batch is half price (pricing).
• OpenAI does not publish a flat per-image USD price for 2.5. For reference, the predecessor gpt-image-2 costs $0.006 (low) / $0.053 (medium) / $0.211 (high) per 1024×1024 image, which is ≈ £0.0045 / £0.040 / £0.16 (image guide).
• [Inference] Runway's resale price for GPT Image 2.5 ($0.16 high, $0.28 xhigh, $0.63 max at 1K/2K) gives a rough ceiling. Direct OpenAI pricing is likely at or below this. Check the usage field in API responses for real costs.
• Audio (not a top-2 pick): gpt-4o-mini-tts costs $0.60 per 1M text-input tokens + $12 per 1M audio-output tokens (≈ £0.45 / £9.07). tts-1-hd costs $30 per 1M characters (≈ £22.67).

Requirements

1. OpenAI Platform account at platform.openai.com (separate from ChatGPT subscriptions) [Fact].
2. API key in the OPENAI_API_KEY environment variable [Fact] (quickstart).
3. Prepaid credit. Usage Tier 1 requires $5 paid (≈ £3.78) and allows $100/month (rate limits) [Fact].
4. API Organization Verification "may" be required before using GPT Image models [Fact] (image guide).
5. SDK: pip install openai or npm install openai [Fact].

How to obtain them

Sign in at platform.openai.com. Add a payment method and credit under Billing, create a key under API keys, and complete Organization Verification in the developer console settings if prompted.

[Uncertain] OpenAI's help-center articles on prepaid billing and Organization Verification returned HTTP 403 to my fetches. I could not quote the exact verification requirements (for example, a government ID) or the processing time.

Other useful info

• [Fact] OpenAI's usage policy requires telling end users that a TTS voice is AI-generated (TTS guide).
• [Fact] Spend limits and alerts can be set per organization or project (rate limits). Set these before handing the key to an agent.

---

2. SINGLE-MEDIA CATEGORIES

2.1 VIDEO

Both video picks are multi-media tools. See 1.1 Google Gemini API (Pick 1) and 1.2 Runway API (Pick 2).

Why Google first, Runway second [Inference]:

• Choose Google for general premium generation at the lowest cost per second with native audio. Omni Flash adds conversational editing.
• Choose Runway when the client needs editorial or HDR deliverables (ProRes, EXR, HDR10), video-to-video editing (Aleph), upscaling, or access to other leading models such as Seedance 2.5 under one key.
• OpenAI Sora is no longer an option (shut down 24 Sep 2026) [Fact].

2.2 IMAGE

Both image picks are multi-media tools. See 1.3 OpenAI GPT Image 2.5 (Pick 1) and 1.1 Google Nano Banana Pro (Pick 2).

Why [Inference]:

• GPT Image 2.5 has the widest quality range (up to max), 4K output, precise editing (Sunburst) and transparent backgrounds.
• Nano Banana Pro is cheaper and more predictable per image ($0.134 at 1K/2K), offers 4K, half-price batch mode and optional Google Search grounding.
• Both are also available through a single Runway key if a seat holder prefers one account.

2.3 AUDIO

Pick 1: ElevenLabs API (dedicated audio)

Why it was chosen [Inference, based on the facts below]

• It covers every premium audio need from one key [Fact]: text-to-speech (Eleven v4, v3, Multilingual v2, Flash), music generation (up to 5 minutes, 44.1 kHz, commercial licensing on Starter+), sound effects, voice cloning, voice changer, voice isolation, dubbing (v2 covers 92 languages) and speech-to-text (API pricing).
• [Fact] ElevenLabs maintains an official MCP server (elevenlabs-mcp) that generates and saves audio files directly from an agent (GitHub: elevenlabs/elevenlabs-mcp), plus an official skill (npx skills add elevenlabs/skills) (quickstart). It is the easiest of all the picks to plug into an agent.
• [Fact] Runway resells ElevenLabs models (Runway models), which suggests other platforms treat it as a premium audio backend [Inference].

Costs [Fact: ElevenLabs API pricing page, 1 Oct 2026]

Plans (monthly; they include usage and add pay-as-you-go overage):

Plan	USD / month	GBP / month (≈)	Included TTS (v4 characters, per page)
Free / Pay-as-you-go	$0 + usage	£0 + usage	10,000
Starter	$6	£4.53	~273,000
Creator	$22 (first month $11)	£16.62 (first month £8.31)	~1,000,000
Pro	$99	£74.81	~4,500,000
Scale	$299	£225.94	~13,591,000
Business	$990	£748.09	~45,000,000

The included-character figures are read from the v4 column of the plan table while v4 is discounted. I did not fully confirm how these quotas map across models.

Per-unit rates:

Product	USD	GBP (≈)
TTS Eleven v4	$0.08 per 1K characters ($0.022 promo until 12 Oct 2026)	£0.060 (promo £0.017)
TTS Eleven v3 / Multilingual v2	$0.08 per 1K characters (~1 min of speech)	£0.060
TTS Flash/Turbo, v3 Conversational	$0.04 per 1K characters	£0.030
Music	$0.15 per minute (+$1.50 per finetune)	£0.11/min (£1.13)
Sound effects	$0.12 per minute	£0.091
Dubbing v2	$2.20 per minute	£1.66

[Fact] Commercial licensing (including for music) requires Starter or above. The free tier is not suitable for client work (pricing).

Requirements

1. ElevenLabs account and a paid plan (Starter or higher for commercial use) [Fact].
2. API key in the ELEVENLABS_API_KEY environment variable [Fact] (quickstart).
3. For the MCP route: uv (Python package runner) installed. The server is started with uvx elevenlabs-mcp [Fact] (GitHub).
4. For the SDK route: pip install elevenlabs [Fact]. Model ID example: eleven_v4.

How to obtain them

Sign up at elevenlabs.io, choose a plan, then create a key in the dashboard's API keys section (quickstart).

Other useful info

• [Fact] The MCP server writes files to ELEVENLABS_MCP_BASE_PATH (default ~/Desktop) and only reads input files inside that folder. Point it at your job's working folder.
• [Fact] The 72% v4 discount ends on 12 Oct 2026. Budget at the regular $0.08 per 1K characters.

Pick 2: Google Gemini TTS + Lyria (see 1.1)

Why second [Inference]: it is far cheaper for narration (≈ $0.0135/min versus ElevenLabs v3 ≈ $0.08/min) and uses the same key as video and image. Lyria 3.5 makes a full song for $0.08. Google describes Gemini 3.8 Flash TTS as "engineered for studio-grade voice fidelity, expressive acting, and long-form stability" [Fact]. However, ElevenLabs has the broader feature set (voice cloning, sound effects, dubbing, voice library) and a ready-made generation MCP, so it ranks first for premium audio.

---

3. Step-by-step: adding a tool to your worker (Claude Code or Codex)

These steps work for any of the four providers. Provider-specific values are in the table at the end of this section.

Step 1: Create the developer account and add billing

Use the provider's developer/API console, not the consumer app. Prepay the minimum and set a spend limit/alert if the provider offers one. Premium video can cost several dollars per attempt.

Step 2: Create an API key and store it as an environment variable

Never paste the key into a chat with the agent, a prompt, or a file that gets committed.

• macOS/Linux: add export PROVIDER_KEY_NAME="your-key" to ~/.bashrc or ~/.zshrc, then open a new terminal.
• Windows: setx PROVIDER_KEY_NAME "your-key", then open a new terminal.
• Restart Claude Code or Codex from that new terminal so it inherits the variable.

Step 3: Install the provider's SDK

Use the pip install … or npm install … command from the table below.

Step 4: Connect the tool to your agent. Choose A or B.

A. MCP server (when the provider has a generation MCP; currently ElevenLabs)

• Claude Code: claude mcp add --transport stdio --env ELEVENLABS_API_KEY=$ELEVENLABS_API_KEY elevenlabs -- uvx elevenlabs-mcp. This is Claude Code's documented --env + -- stdio pattern (Claude Code MCP docs). Check it with /mcp inside a session.
• Codex: codex mcp add elevenlabs --env ELEVENLABS_API_KEY=$ELEVENLABS_API_KEY -- uvx elevenlabs-mcp. Alternatively, add a [mcp_servers.elevenlabs] table to ~/.codex/config.toml with command = "uvx", args = ["elevenlabs-mcp"] and the key passed via env_vars (Codex MCP docs).
• [Inference] Passing $VAR on the command line writes the key's value into the agent's config file. Keep that file private. In Codex, env_vars = ["ELEVENLABS_API_KEY"] forwards the variable without storing it.

B. A small "skill" that wraps the SDK (works for every provider) Both Claude Code and Codex support the open Agent Skills format: a folder containing a SKILL.md with name and description frontmatter, plus optional scripts.

• Claude Code reads personal skills from ~/.claude/skills/<skill-name>/SKILL.md (Claude Code skills).
• Codex reads them from ~/.agents/skills/<skill-name>/SKILL.md, or .agents/skills inside a repo (Codex skills).

Put a short script in the skill folder (for example, generate.py) that calls the SDK and saves the output file. Use SKILL.md to say when to use it, which model ID to default to, cost guardrails (for example, "use Veo 3.1 Fast for drafts; only use Standard/4K for the final render") and where to save files. Installing an official skill package is the quickest way to do this:

• Google: npx skills add google-gemini/gemini-skills --skill gemini-api-dev --global
• ElevenLabs: npx skills add elevenlabs/skills

Step 5: Run a cheap test

Ask the agent for one low-cost output. Then confirm that the file was saved and that the charge shows up in the provider's usage dashboard. Suggested tests:

• 4–5 s on Veo 3.1 Lite/Fast or Gen-4.5
• one 1K image at medium quality
• one short sentence of TTS

Step 6: Write a default policy for premium jobs

Record these in CLAUDE.md / AGENTS.md or the skill:

• which model to use for drafts and which for finals
• maximum spend per job
• output folder
• the AI-disclosure rule (required by OpenAI for TTS)
• paid tier only for client data (Google's free tier may use your content to improve its products)

4. Limits, gaps and suggested follow-ups

What I'm confident in

Prices, model IDs, key names, billing minimums and MCP/skill commands were all read directly from official pages on 1 Oct 2026. I believe the report is complete enough for a seat holder to choose tools and set them up.

Where data is incomplete or uncertain

1. "Best" is a judgement, not a measured ranking [Inference]. The brief excluded reviews and customer stories, so I had no independent quality benchmarks. The rankings rest on official capabilities, output formats, pricing and agent integration. Follow-up: run a small paid bake-off with the same 5–10 prompts across Omni Flash, Veo 3.1, Gen-4.5 and Seedance 2.5 (and the image/audio equivalents), and have a human score the outputs.
2. OpenAI per-image cost for GPT Image 2.5 is published only as token rates. Follow-up: generate test images at each quality level and record the usage numbers.
3. OpenAI Organization Verification and prepaid billing details. The help-center pages returned 403. Follow-up: read them from a logged-in browser.
4. Runway's generation MCP (mcp.runwayml.com). I did not confirm whether it uses API credits or a web-app plan, or how it authenticates.
5. GBP figures are conversions, not provider GBP prices, and exclude VAT. Follow-up: check what a UK-billed account is actually charged, including VAT and currency.
6. ElevenLabs plan quotas shown are v4 character equivalents during a promotion. Their mapping to other models (v3, music) is not fully clear from the page.
7. Fast-changing data. Several Google models are "preview". The ElevenLabs promo ends 12 Oct 2026, and Gemini TTS prices double on 1 Jan 2027. Sora was retired one week before this research. Follow-up: re-check prices quarterly.

Gaps in the instructions, and useful information that wasn't asked for

• Licensing, IP and content-policy terms for commercial client deliverables (who owns the output, watermarking/C2PA, disclosure rules) were not requested but matter for premium jobs. OpenAI's TTS disclosure rule and ElevenLabs' "commercial license on Starter+" show these differ by provider. Follow-up: a job comparing each provider's commercial-use terms, provenance/watermark behaviour, and likeness/voice-cloning consent rules.
• Data privacy: Google's free tier marks content as used to improve products. Client confidentiality should be a standard checklist item. Follow-up: a short data-handling comparison (retention, training use, UK/EU data residency).
• Rate limits and concurrency (usage tiers at Google, OpenAI and Runway) affect whether a worker can deliver a large job on time. I noted the tiers but did not map them to job sizes.
• The brief didn't define "worker" technically (local CLI, cloud sandbox, OS). I assumed a local Claude Code or Codex CLI. Follow-up: if IMD workers run in sandboxes without a browser, the OAuth-based MCPs (Runway Dev) may not work, and env-var + SDK skills should be the standard.
