What it does

Assemblyai Core Workflow B is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze and operate an AssemblyAI Streaming v3 session with safe tokens, audio framing, turn handling, and explicit termination. Use when building live captions or voice agents. Trigger with "AssemblyAI streaming", "AssemblyAI v3 WebSocket", or "live transcript".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live AssemblyAI work requires network access

It sits in Backend & APIs, covering Speech recognition and synthesis, Realtime and WebSockets and Transcription. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Building live captions
  • With AssemblyAI streaming
  • AssemblyAI v3 WebSocket
  • Live transcript

Example prompts

  • “AssemblyAI streaming”
  • “AssemblyAI v3 WebSocket”
  • “live transcript”
  • “/assemblyai-core-workflow-b”

Requirements

  • A credential in ASSEMBLYAI_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code; live AssemblyAI work requires network access
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Confirm live-capture consent, region, model, encoding, and turn policy.
  2. Mint a short-lived single-use token for untrusted clients.
  3. Verify Begin before sending correctly paced audio frames.
  4. Order turns and persist only approved finalized content.
  5. Treat reconnect as a new governed session boundary.
  6. Send termination, await confirmation, stop capture, and record duration.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ASSEMBLYAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; live AssemblyAI work requires network access

    From compatibility in the SKILL.md frontmatter.

Context cost

Assemblyai Core Workflow B loads about 1.1k tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 466 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AssemblyAI Streaming v3 Session

Overview

Operate live transcription around the current v3 message and billing lifecycle. Govern capture, credentials, finalized content, reconnects, and termination separately.

Prerequisites

  • The target repository or integration path and the requested operator outcome.
  • The AssemblyAI project, environment, region, data classification, and accountable owner.
  • Current first-party documentation plus credentials only for a narrowly approved live check.

Current Contract

Use wss://streaming.assemblyai.com/v3/ws or the approved residency host. Handle Begin, partial and finalized Turn messages, and Termination. Match encoding and sample rate, pace audio correctly, use backend-minted tokens in untrusted clients, and terminate explicitly so abandoned connections do not continue billing.

Authentication

For live work, inject ASSEMBLYAI_API_KEY from an approved secret manager and send the raw value only in the AssemblyAI Authorization header to the configured first-party host. Never print, commit, place in a URL, or expose it to an untrusted client. Callback secrets and temporary streaming tokens are separate credentials.

Instructions

  1. Confirm live-capture consent, region, model, encoding, and turn policy.
  2. Mint a short-lived single-use token for untrusted clients.
  3. Verify Begin before sending correctly paced audio frames.
  4. Order turns and persist only approved finalized content.
  5. Treat reconnect as a new governed session boundary.
  6. Send termination, await confirmation, stop capture, and record duration.

Tool Discipline

Use Read, Glob, and Grep to inspect repository code, configuration, fixtures, and evidence. Use Write and Edit only for approved implementation or documentation changes. Do not call AssemblyAI, upload audio, open a streaming session, mint a token, replay a callback, deploy, rotate a key, or delete a transcript merely because this skill was invoked.

Approval Boundaries

Require an accountable owner before live audio processing, production credential or endpoint changes, paid model or capacity changes, content retention, callback replay, deployment, or deletion. Read-only repository inspection and synthetic offline validation do not authorize live vendor actions.

Failure Modes

  • The /v2/realtime/ws route is legacy and must migrate.
  • Encoding or sample-rate mismatch is not repaired by retries.
  • Missing termination evidence leaves cost and completeness uncertain.

Output

Return the operation scope, environment, region, contract surface, authorization class, model and feature decisions, deterministic validation results, content-free identifiers, risks, cleanup or rollback state, and a concise pass/fail receipt. Exclude credentials, signed URLs, audio, transcript text, prompts, and customer-derived content.

Example

  • Start with the named environment, approved regional host, synthetic fixture identity, and bounded operation budget.
  • Finish with safe IDs, contract and assertion counts, terminal state, cleanup status, and the decision owner; never reproduce speech content.

Validation

Rerun the smallest relevant deterministic check, compare actual state with the requested outcome and current first-party contract, verify sensitive fields are absent from evidence, and confirm rollback, termination, or deletion state before reporting success.

References

Review the dated first-party evidence map before relying on any model, parameter, limit, price, region, or lifecycle claim.
