Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Data Exfiltration · line 226 Code or instructions that leak agent conversation context to external services, potentially exposing sensitive user interactions.Fix: Remove any code that sends prompts, responses, or session data externally. Preserve user privacy; never exfiltrate conversation content.
- medium Data Exfiltration · line 51 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00125 | $0.06240 |
| Opus 5 | $0.00063 | $0.03120 |
| Sonnet 5 | $0.00025 | $0.01248 |
| Haiku 4.5 | $0.00013 | $0.00624 |
Grade A, and why
assemblyai-transcription scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AssemblyAI transcription for media-production agents
Use AssemblyAI when the production job needs reliable transcript artifacts from recorded or live speech, especially when the transcript must drive captions, clip selection, speaker turns, show notes, chaptering, translation, moderation, or compliance review.
Treat this as a provider skill, not a generic ASR primer. Check the live AssemblyAI docs before implementing code in production because model names, pricing, add-ons, rate limits, and data-retention settings are volatile. The facts below were verified against official AssemblyAI documentation on 2026-07-10.
Pick the product surface first
AssemblyAI exposes several surfaces that look similar but serve different production needs.
Documented facts:
- Pre-recorded STT is the main batch/async API for media files. Submit
audio_urlor upload a local file first, then pollGET /v2/transcript/{id}or use webhooks until the transcript iscompletedorerror. The returned transcript includes text, metadata, words with millisecond timestamps, and optional feature outputs. Source: https://www.assemblyai.com/docs/pre-recorded-audio/getting-started/transcribe-an-audio-file - Sync STT is for short clips in a single HTTP request, with no polling or session management. Official docs describe it as accepting audio clips from 80 ms to 120 s. Use it for short voice-agent turns, quick QC snippets, or small app interactions, not long podcasts or interviews. Sources: https://www.assemblyai.com/docs/sync-stt/getting-started/transcribe-a-short-audio-file and https://www.assemblyai.com/docs/sync-stt/audio-requirements
- Real-time STT streams audio over WebSocket (
wss://streaming.assemblyai.com/v3/ws) and emitsBegin, repeatedTurn, andTerminationevents. Use it for live captioning, voice agents, live meeting assistants, or real-time production monitors. Word timings are in milliseconds. Source: https://www.assemblyai.com/docs/streaming/getting-started/transcribe-streaming-audio - Streaming is billed for the duration the WebSocket is open, not the amount of audio sent. Unclosed sessions auto-close after 3 hours and can bill for the full session duration. Source: https://www.assemblyai.com/docs/billing-and-pricing
- Use temporary streaming tokens for browser clients; never expose the account API key in client-side code. Source: https://www.assemblyai.com/docs/streaming/getting-started/transcribe-streaming-audio
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

assemblyai-transcription is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 2mo ago), licensed MIT. It adds 125 tokens to every session and 6,240 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
