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 | $0.00030 | $0.02827 |
| Opus 5.5 | $0.00012 | $0.01131 |
| Sonnet 5.5 | $0.00006 | $0.00565 |
| Haiku 4.5 | $0.00003 | $0.00283 |
Grade A, and why
tether scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tether
Use Tether as the visibility and lifecycle boundary for durable development workloads. Hermes is a configurable reference adapter only: do not import, embed, or require Hermes in Tether, and do not bypass Tether with direct tmux commands.
Install
Choose the source that matches the Tether installation:
Stable v0.8.0:
hermes skills install https://raw.githubusercontent.com/moneycaringcoder/herdr-tether/v0.8.0/integrations/hermes/SKILL.md
Development (main):
hermes skills install https://raw.githubusercontent.com/moneycaringcoder/herdr-tether/main/integrations/hermes/SKILL.md
Immutable reviewed commit:
TETHER_SKILL_REF=FULL_COMMIT_SHA_YOU_REVIEWED
hermes skills install "https://raw.githubusercontent.com/moneycaringcoder/herdr-tether/${TETHER_SKILL_REF}/integrations/hermes/SKILL.md"
The skill is available in new Hermes sessions after installation.
When to Use
Use this skill when a user wants to:
- see repositories or durable workloads visible to Tether;
- start a user-chosen command in a Tether-owned workload;
- reopen, restart, stop, or remove a specific Tether-owned workload;
- compare workload state across configured local and remote hosts;
- configure and view an opt-in orchestration group; or
- hand an approved group to Herdr's interactive Observer or Mission Control surface when the installed Tether and Herdr versions support it.
Preflight
- Resolve the Tether executable from the current environment. Use
herdr-tetherunless the user supplied another executable name. Do not guess an absolute path. - Run
herdr-tether --versionandherdr-tether snapshot. If either command is unavailable, explain that Tether must be installed and configured on the machine where Hermes executes. - Parse snapshot stdout as JSON. Require
schema_versionto equal1; if it does not, stop and report the unsupported version rather than guessing field meanings. - Treat
completion: "partial"as usable degraded data, not as an empty or complete inventory. Preserve each typed status when reporting why a host, repository scan, workload probe, or external catalog is incomplete.
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.

tether is a skill published in the GitHub repository moneycaringcoder/herdr-tether (5 stars, last pushed 21d ago), licensed MIT. It adds 30 tokens to every session and 2,827 once invoked, about $0.0001 per session on Opus 5.5. 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.
