Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium analysis-evasion · line 1 Suspicious Unicode normalization or mixed-script contentFix: Review the flagged content for security risks. Ensure no credentials, secrets, or sensitive data are exposed.
- medium Output Handling · line 390 Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.Fix: Set explicit limits on output length, generation count, and rate. Use max_tokens and truncation to prevent unbounded output.
What it costs to keep this loaded
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 | $0.00117 | $0.07703 |
| Opus 5 | $0.00059 | $0.03852 |
| Sonnet 5 | $0.00023 | $0.01541 |
| Haiku 4.5 | $0.00012 | $0.00770 |
Grade A, and why
elevenlabs-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.
How it starts
The opening of the file, as written. The whole thing — 520 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ElevenLabs TTS production
Treat speech generation as casting, script adaptation, performance direction, rendering, and finishing—not as a single API call. Optimize for the listener and delivery channel, then for latency or cost.
Evidence labels
Interpret guidance by its label:
- Documented — ElevenLabs documentation, API reference, or current policy states this.
- Standard — a named speech/audio standard states this.
- Production heuristic — a practical starting point; validate it on the actual voice, model, script, and channel.
- Inference — a conclusion drawn from documented behavior; test before relying on it.
Volatile ElevenLabs facts in this skill were checked on 2026-07-09. Before a consequential production run, query GET /v1/models, inspect the chosen voice, and recheck the current API reference, plan entitlements, policies, and terms. Never infer current availability from an old voice name or model list.
Scope boundary
Use this skill for rendered speech and voice production. Do not expand into:
- music or sound-effect generation;
- dialogue-system logic, turn-taking, tools, telephony orchestration, or conversational-agent prompting;
- speech-to-speech except to explain why it is not TTS;
- general transcription, dubbing, or localization workflows;
- legal conclusions. Flag rights questions for qualified review.
Speech-to-text may be used only as one TTS QA signal. It must not replace listening.
Start with a production contract
Before selecting a model, write down:
- audience, language, regional accent, and accessibility needs;
- medium and destination: video narration, audiobook, ad, game character, course, IVR, or live playback;
- performance: credible, intimate, restrained, comic, urgent, dramatic, etc.;
- target duration and synchronization constraints;
- latency mode: offline, complete-text streaming, or incremental-text streaming;
- volume of text and revision pattern;
- identity requirement: stock/library, designed, IVC, or PVC;
- pronunciation list: names, brands, acronyms, numbers, URLs, formulae, and code;
- delivery format, sample rate, channels, loudness specification, and caption/timing need;
- rights, consent, disclosure, privacy, plan, and budget constraints.
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.

elevenlabs-tts is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 2mo ago), licensed MIT. It adds 117 tokens to every session and 7,703 once invoked, about $0.0006 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 2026-09-03.
