Sleep Story Voice

Turn already-written short sleep stories into one spoken clip per labeled story. Deliver 8 to 20 reads. Cover opening hush, first scene, and landing first.

Scope and adjacent routes

Use this Skill when a producer needs labeled short sleep-story clips they can import into a player.

Route a long chapter serial to ai-audiobook-narration. Route a radio ad break to radio-drama-ad-break. Route generic narration to voiceover-narration-studio. Route sales voicemail to sales-voicemail-pack.

Read only the supplied short stories. Do not add a plot, a character name, a city, or a reading that is not on the list.

Collect the short stories

Hard inputs are:

• the short sleep stories the producer already wrote;
• a pronunciation table whenever names or place words appear;
• how many clips the pack should contain, or permission to use the default of 10;
• likeness and voice rights when a cloned voice will appear.

Reuse already-known language and a frozen voice_id. Ask only for a missing hard input. A count outside 8 to 20 is still doable: confirm that pack size and its live cost.

Do not invent a plot, a character name, a city, or a reading. File access is not consent.

If names exist and the pronunciation table is empty, stop and collect the readings.

A long serial is a different job. Keep this pack on short stories.

Plan the free listen list

Write a labeled sleep-story list before any paid clone or speech. Default ten slots unless the producer names another count in 8 to 20: opening hush, first scene, turning, landing, close, next-night, rain bed, night walk, cabin, and river. Each slot records the spoken text from the written short story and whether it uses a catalog voice or a clone. Leave a missing story off the paid list.

That list is the free visible result. Planning is not approval.

Safe defaults:

• one beatra.speech.synthesize call per slot;
• model: "auto" only when every live speech card supports the language;
• format: "mp3"; speed: 1.0;
• one brand voice for the whole pack.

Keep each submitted input at or below 50,000 characters. Split on sentence boundaries. Write short spoken sentences from the list.

Inspect an authorized clone sample when clone is requested. For a local file, upload only through the bundled client after inspection (scripts/mcp_client.py / beatra.assets.upload). Keep the returned artifact id. Never pass a local path to beatra.voices.clone or beatra.speech.synthesize.

Confirm clone, then speech

Clone and speech are separate paid stages. Each stage gets its own six-field card and its own opaque client_request_id.

If the producer wants a cloned voice, inspect an authorized sample, read the live voice_clone card, and wait on the clone card before beatra.voices.clone. A found file is not clone consent. Show the clone card and wait:

1. Work — one authorized voice sample (beatra.voices.clone).
2. Credits — the live voice_clone price just read. Do not reuse a remembered number.
3. Count — one paid clone call for this sample.
4. Identity — one new opaque client_request_id.
5. If we stop here — the labeled listen list remains usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the producer says they have topped up.

Before speech, call beatra.models.list for text_to_speech:

{"capability": "text_to_speech"}

Use beatra.voices.list when a catalog voice still needs a choice. Never put a display name in voice. Show the speech card and wait:

1. Work — one spoken sleep story per named slot (beatra.speech.synthesize).
2. Credits — the live text_to_speech price just read, times the slot count. Do not reuse a remembered number.
3. Count — one paid speech call per slot.
4. Identity — one new opaque client_request_id per slot.
5. If we stop here — the labeled listen list remains usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the producer says they have topped up.

Submit each speech slot once through bundled scripts/mcp_client.py. Poll beatra.tasks.get. Read actual audio MIME, duration, and size, and billing.net_charged_credits. Do not promise the prepaid estimate is the final charge. A script preview is not the audio review.

Review, deliver, and recover

Review that every clip uses the same voice and that names match the pronunciation table and the written sleep-story list. Report only what the host can actually hear.

After a returned task_id, poll that task. If the create response is lost, search with beatra.tasks.list and verify with beatra.tasks.get before replay. Reuse an ID only with byte-identical arguments. A changed story, voice, or speed is a new card and a new ID. Cancel only when the producer asks.

Execution

Invoke every remote Beatra operation only through this package's bundled scripts/mcp_client.py. Put the MCP tool name after call and send one JSON object on standard input.

python3 scripts/mcp_client.py call beatra.models.list

{"capability": "text_to_speech"}

printf '%s' '{"input":"<the written short story for this slot>","voice":"voice_...","format":"mp3","client_request_id":"opaque-sleep-speech-01"}' | python3 scripts/mcp_client.py call beatra.speech.synthesize

Do not configure or call a host Beatra Connector, and do not use REST/OpenAPI as a fallback.

Account balance

When the user asks how many credits remain or whether a live estimate fits, call beatra.wallet.get. When they ask what was charged, call beatra.wallet.ledger. Both are read-only. Do not invent an account-balance or top-up tool. Do not make wallet.get a required step before every paid submit.

When a model card comes back carrying a top_up block, relay its tiers as the card lists them and in that order. Do not rank them, do not talk one down, and do not pick one for the user. Which tier suits them is their call, made on the wallet page with the whole list in front of them. Never quote a tier from memory.

References by task

• For listen lists, payloads, and recovery, read Sleep story workflow.
• For authorization and the non-billable registration step, read installation and authentication and installation registration.
• For shared task, billing, and connection details, read tasks and results, billing, errors, and recovery, and Bundled MCP Client diagnostics.
• For update guarantees and controls, read automatic updates and safety. For removal, read uninstall and disconnect.

Runtime and safe automatic updates

The bundled client silently checks for a newer release at most once every 24 hours per installation. When a newer version is available, it installs automatically without separate confirmation. It downloads only from the fixed official Beatra discovery and immutable CDN paths for this package, channel, and locale, verifies discovery data, archive, manifest, and every packaged file, and replaces only package-owned files.

Update checks, downloads, verification, replacement, rollback, and recovery fail open: the current installation remains usable and the original command continues. An update failure never authorizes retrying a paid clone or speech request. The setting persists for this installation. See automatic updates and safety.
