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 | $0.00032 | $0.00646 |
| Opus 5 | $0.00016 | $0.00323 |
| Sonnet 5 | $0.00006 | $0.00129 |
| Haiku 4.5 | $0.00003 | $0.00065 |
Grade A, and why
unseen-servant 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unseen Servant
Run a persistent background agent that handles mundane, repeating tasks silently.
What This Skill Does
Use this spell when you need a tireless helper that organizes, tidies, triages, and maintains without requiring your constant attention. In this grimoire, Unseen Servant is treated as a literal spell with a shipping-now delivery profile. Canonical reference input: Unseen Servant (spell).
When To Use
- Routine maintenance tasks keep piling up: dependency updates, stale branch cleanup, inbox triage, log rotation.
- You want a helper that runs continuously in the background and only surfaces when something needs your attention.
- The work is important but low-priority - it should happen reliably without competing for your focus.
Prerequisites
- No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.
Procedure
- Restate the target, the success condition, and any no-touch boundaries before taking action.
- Define the servant's mandate: which tasks, which surfaces, and what scope boundaries.
- Configure the cadence - continuous, periodic, or event-triggered.
- Let the servant operate silently, logging its actions for later review.
- Review the activity log periodically and adjust the mandate or dismiss the servant when done.
- Stop for explicit confirmation before taking a live action that changes access, triggers an alert, or touches a real system boundary.
- Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
Deliverables
- A running background process or agent loop with a clear task mandate.
- An activity log of everything the servant touched, with timestamps.
- A dismiss or pause mechanism so the user stays in control.
Pitfalls / Guardrails
- Treat the live action surface as real operational work, not decorative lore.
- The servant does not expand its own mandate - it only touches what the user pre-approved.
- All actions must be logged and reviewable. Silent operation does not mean unaccountable operation.
- Provide a clear dismiss mechanism - the user must always be able to stop the servant immediately.
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.

unseen-servant is a skill published in the GitHub repository Hmbown/Wizards-of-the-Ghosts (107 stars, last pushed 5mo ago), licensed CC0-1.0. It adds 32 tokens to every session and 646 once invoked, about $0.0002 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.
