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.

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 | $0.00044 | $0.03168 |
| Opus 5 | $0.00022 | $0.01584 |
| Sonnet 5 | $0.00009 | $0.00634 |
| Haiku 4.5 | $0.00004 | $0.00317 |
Grade A, and why
telephony 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 6d 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.
This is a copy
91% identical to telephony — 58 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Telephony — Numbers, Calls, and Texts without Core Tool Changes
This optional skill gives Hermes practical phone capabilities while keeping telephony out of the core tool list.
It ships with a helper script, scripts/telephony.py, that can:
- save provider credentials into
${HERMES_HOME:-~/.hermes}/.env - search for and buy a Twilio phone number
- remember that owned number for later sessions
- send SMS / MMS from the owned number
- poll inbound SMS for that number with no webhook server required
- make direct Twilio calls using TwiML
<Say>or<Play> - import the owned Twilio number into Vapi
- place outbound AI calls through Bland.ai or Vapi
What this solves
This skill is meant to cover the practical phone tasks users actually want:
- outbound calls
- texting
- owning a reusable agent number
- checking messages that arrive to that number later
- preserving that number and related IDs between sessions
- future-friendly telephony identity for inbound SMS polling and other automations
It does not turn Hermes into a real-time inbound phone gateway. Inbound SMS is handled by polling the Twilio REST API. That is enough for many workflows, including notifications and some one-time-code retrieval, without adding core webhook infrastructure.
Safety rules — mandatory
- Always confirm before placing a call or sending a text.
- Never dial emergency numbers.
- Never use telephony for harassment, spam, impersonation, or anything illegal.
- Treat third-party phone numbers as sensitive operational data:
- do not save them to Hermes memory
- do not include them in skill docs, summaries, or follow-up notes unless the user explicitly wants that
- It is fine to persist the agent-owned Twilio number because that is part of the user's configuration.
- VoIP numbers are not guaranteed to work for all third-party 2FA flows. Use with caution and set user expectations clearly.
Decision tree — which service to use?
Use this logic instead of hardcoded provider routing:
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.

telephony is a skill published in the GitHub repository cyborg-garden/hermes-agent-mt (13 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 3,168 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to telephony, differing in 58 lines, and is treated as a copy.
