Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00022 | $0.00376 |
| Opus 5 | $0.00011 | $0.00188 |
| Sonnet 5 | $0.00004 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
tts 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.
What it actually says
feinklang — ElevenLabs voiceover
feinklang is a command on your PATH — no file paths, no cd, no
${CLAUDE_PLUGIN_ROOT}. Requires ELEVENLABS_API_KEY (an export, or a line in
~/.env). Default voice: Hale.
Quick Start
feinklang tts --text "Hello, this is a test." --out voiceover.mp3
See references/parameters.md for all flags, models, and format options.
Synthesize speech
Key options: --voice-id (name or ID), --model-id, --format, --stability,
--similarity-boost, --speed, --play. Write outputs into the project
(e.g. a beats directory under ${CLAUDE_PROJECT_DIR}) so downstream plugins
can consume them.

For other plugins (capability hand-off)
Call feinklang tts --text "…" --out <project-path> and read the resulting
file. Do not reference feinklang's internal files; the CLI is the entire
contract. If feinklang is not on PATH, ask the user for the audio instead.

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.

tts is a skill published in the GitHub repository marsmike/feinschmiede (3 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 376 once invoked, about $0.0001 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 2026-08-31.
