refine-spell

refine-spell is a command for coding agents from redhuntlabs/wizard. It costs 13 tokens per session (168 once invoked), scanned A, original, MIT.

A command for improving an existing spell, meaning a saved workflow, based on how it worked in practice.

In plain words
What is it for?
Use it to revise a named workflow, add or clarify steps or examples, re-run its tester, and save the updated version.
Why use it?
It ensures changes are tested again and that the workflow’s version is updated appropriately.

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

refine-spell 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 4d 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 it actually says

/refine-spell

Invoke the refining-a-spell skill to update a spell in your library.

Usage

/refine-spell writing-an-email
/refine-spell writing-an-email --bump minor

What happens next

The skill walks you through:

  1. Loading the current SKILL.md
  2. Identifying what changed (new step, clearer wording, better example, etc.)
  3. Re-running the tester (mandatory after any change)
  4. Bumping the version field appropriately
  5. Saving back to your WIZARD_HOME

Re-testing is non-skippable. A change without a re-test is treated like a new build that skipped try-it.

Changes

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.
