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 | $0.00043 | $0.00830 |
| Opus 5 | $0.00022 | $0.00415 |
| Sonnet 5 | $0.00009 | $0.00166 |
| Haiku 4.5 | $0.00004 | $0.00083 |
Grade A, and why
sleight-of-hand 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sleight of Hand
Make the tiny exact change that fixes the problem without disturbing the room.
What This Skill Does
Sleight of Hand is not about solving a problem — the solution is already known. It is about executing a known change with zero collateral damage. The skill is precision, not creativity. In this grimoire, Sleight of Hand is treated as a metaphorical skill with a shipping-now delivery profile. Canonical reference input: Sleight of Hand (skill).
When To Use
- Activate this spell when the user requests a surgical, minimal edit where:
- The exact change is known (before value → after value)
- Only 1–3 specific locations need modification
- The user names the file, line, or exact string to change
- The request emphasizes precision: "just this", "only this one", "don't touch anything else"
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.
- Isolate: Identify the smallest possible surface area that carries the fix. Confirm the exact match target — file, line, or pattern. If the match is ambiguous (could hit multiple places), stop and ask for clarification. Never guess.
- Stage: Show the exact change before applying it. Present a before-and-after diff of only the affected lines. Verify that neighboring lines, formatting, and unrelated occurrences are untouched.
- Deliver: Apply the edit. Return: (a) the minimal diff, (b) a confidence statement confirming what was changed and what was intentionally left alone, (c) a one-line rollback instruction (the inverse edit).
- Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
Deliverables
- A targeted patch, replacement pattern, or edit instruction.
- Proof of what changed and what was intentionally left alone.
- A rollback note in case the tiny move still misfires.
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.

sleight-of-hand 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 43 tokens to every session and 830 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.
