What it does

Conversation Chat is an agent skill from receptron/mulmocast-cli. Create a conversation practice chat MulmoScript with speech bubble UI and character illustration (voiceover approach). Use when the user wants to create English conversation practice content.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `calc_voiceover_timing.ts`).

It sits in Media & Creative, covering Language learning and Text to speech and voice. The repository describes itself as: AI-powered podcast & video generator.

When your agent uses it

  • The user wants to create English conversation practice content
  • Tasks that involve Language learning
  • Tasks that involve Text to speech and voice

Example prompts

  • “/conversation-chat”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Content Generation
  2. Create Initial Script (without timing)
  3. Generate Audio & Calculate Timing
  4. Generate Movie

What it can do on your machine

Read from SKILL.md and the folder at commit 5ef895b. 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
    • Write
    • Edit
    • Bash
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • yarn
    • magick
    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use yarn and npx, which can reach the network depending on how they are called.

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Conversation Chat loads about 3k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 816 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Bash, Grep, Glob

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 816 words (~2,964 tokens).

“Create a speech-bubble style conversation practice video using MulmoCast's voiceover approach. The video shows animated speech bubbles appearing one at a time over a background gradient with a character illustration at the bottom.”
