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 | $0.00033 | $0.00986 |
| Opus 5.5 | $0.00013 | $0.00394 |
| Sonnet 5.5 | $0.00007 | $0.00197 |
| Haiku 4.5 | $0.00003 | $0.00099 |
Grade A, and why
discovering-spells 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Discovering Spells
What this does
Lists spells available in the current session: bundled seeds, the user's personal library, and (optionally) updates available for overrides.
Output is grouped, scannable, and ranked by relevance to the user's recent context.
When to use
- User invoked
/list-spells - User asks "what skills do I have?" or "what spells exist?"
- User wants to see updates to their overrides
What you bring (Inputs)
- (Optional) Filter flags:
--kind,--audience,--mine,--bundled,--updates - (Optional) Recent context (used for ranking; auto-extracted)
What you get (Output)
A grouped list of matching spells, each shown as: name — description (kind / audience / version).
How it works (Steps)
This is a workflow.
Stages
Stage 1: Resolve sources
Default sources: bundled spells/ + $WIZARD_HOME. If --mine, only personal. If --bundled, only bundled.
Stage 2: Apply filters
Apply each flag in turn. Filter by kind, audience, etc. as the user specified.
Stage 3: Detect overrides and updates
For each personal spell, check if a bundled spell with the same name exists.
If yes and the bundled version is newer than the personal version, mark the entry with (update available: bundled vX.Y.Z).
If --updates flag is set, only show entries where an update is available.
Stage 4: Rank by relevance
Rank by:
- Update available (top, if
--updates) - Recently invoked
- Trigger keyword overlap with recent user messages
- Alphabetical within group
Stage 5: Group and print
Group by kind, then by audience. Print:
Discipline (3)
- verifying-before-citing — Use when about to state a factual claim... (researcher / 1.0.0)
- decisions-need-an-alternative — Use when making a choice... (anyone / 1.0.0) [update available: 1.1.0]
...
Workflow (5)

Show counts in headers. If a group is empty, omit it.
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.

discovering-spells is a skill published in the GitHub repository redhuntlabs/wizard (11 stars, last pushed 6mo ago), licensed MIT. It adds 33 tokens to every session and 986 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.
