mage-hand is a skill for Claude Code, Codex from Hmbown/Wizards-of-the-Ghosts. It costs 21 tokens per session (905 once invoked), scanned A, original, CC0-1.0.

A guide for making small, precise changes to files, records, or other lightweight system data with clearly limited scope.

In plain words
What is it for?
It helps update specific fields or values, apply conditional edits, skip invalid items, and report exactly what changed.
Why use it?
It reduces accidental changes by validating each requested item and respecting explicit boundaries about what must remain untouched.

Token cost

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.

Security

Grade A, and why

mage-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.

What This Skill Does

Use this skill for small, careful remote manipulations where dexterity matters more than force. In this grimoire, Mage Hand is treated as a hybrid spell with a shipping-now delivery profile. Canonical reference input: Mage Hand (spell).

When To Use

  • Trigger this spell when the request asks for surgical, narrow edits to existing objects with explicit boundaries on what NOT to touch. Look for:
  • Specific identifiers: file paths, ticket IDs, record keys, field names, audience names
  • Constraint language: "only", "but don't touch", "leave X alone", "if X then stop"
  • Single-field or single-value changes: "change max_attempts from 3 to 4", "patch reply_to_email"
  • Conditional execution with early-exit: "only if each has approval, otherwise stop and return the exception list"
  • Audit expectations: "show the diff", "tell me the exact line", "report skipped IDs"
  • Small batch operations with per-item validation: "move tickets A, B, C but skip any missing X"

Prerequisites

  • No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.

Procedure

  1. Restate the target, the success condition, and any no-touch boundaries before taking action.
  2. Restate boundaries before acting: Name the exact target, the success condition, and what must NOT be touched.
  3. Scope to the smallest edit surface: Change one field, one line, one ticket state. Do not rewrite surrounding content.
  4. Apply with diff or state proof: Show what changed. Confirm adjacent values are untouched.
  5. Report exceptions, not just successes: If any item in a batch fails validation or lacks a prerequisite, stop and return the failure list. Do not silently skip.
  6. Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.

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.
