What it does
Demo With Narration is an agent skill from lexler/skill-factory. Demos working software: first proves every claimed behavior by exercising the real artifact, then replays the proof as a slow, voice-narrated walkthrough. Use when the user asks for a demo or to be shown that something works.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Text to speech and voice. The licence is Apache-2.0.
When your agent uses it
- The user asks for a demo
- Be shown that something works
Example prompts
- “Use the demo-with-narration skill to demo working software: first proves every claimed behavior by exercising the real artifact, then replays the…”
- “/demo-with-narration”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e262032. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Demo With Narration loads about 715 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 428 words of instructions outside code blocks.
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.

Demo With Narration
STARTER_CHARACTER = 🎬
A demo is a proof performed twice: once fast and private to convince yourself, once slow and narrated to convince the person watching.
Stage 1: Self-demo
Exercise the real artifact the way its consumer will — the built binary, the running app. A green test suite is the starting point, not the proof.
- Check every behavior you intend to claim: the happy path, each refusal path with its exact stderr reason and exit code, every way the session can end.
- Probe at least one path beyond the obvious ones (quit from the menu, not just close the window) — the extra path is where green-suite bugs hide.
- A detached GUI launch loses its exit status: wrap the launch in a subshell that writes
$?to a file, read the file after the window closes. - Confirm a window really rendered with a screenshot; drive close and quit through accessibility clicks.
Done when every behavior you will claim in the walkthrough has been observed working, and any bug found is fixed and re-proven.
Stage 2: Narrated walkthrough
Replay the proof slowly. The person asked to follow along, so pace for their eyes and ears.
- Announce each step by voice (
speak) before acting: what is about to happen, what to watch for. Pause a beat so the voice finishes before the action starts. - One step per command, numbered. Each step proves exactly one claim.
- When something appears on screen, say how long it will stay and leave it there — ten seconds for a window is enough to actually look at it.
- After each step, one or two sentences of text recapping what was just proven.
- Order the steps as an argument: the input artifact first, then the refusal paths with their exit codes, then the happy path, then every way the session can end.
- Include at least one step that can only pass if the whole pipeline works — a validation error from the deepest layer surfacing at the outermost one — rather than only surface behaviors.
Show full SKILL.md (95 more words)Show less
Done when every step was announced before it ran, each claim from the self-demo appeared in exactly one step, and a final recap lists every step.
Desktop-automation safety
A System Events keystroke lands on the frontmost application, whatever process the tell block names.
- Click the specific button or menu item through accessibility instead of synthesizing keystrokes.
- When a keystroke is unavoidable: bring the target frontmost, read back which app is actually frontmost, and type only if it matches the target.
- After any slip, list the open windows and confirm nothing else was harmed before continuing.
