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 | $0.00019 | $0.00591 |
| Opus 5 | $0.00010 | $0.00296 |
| Sonnet 5 | $0.00004 | $0.00118 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
mdfind 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 6d 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/mdfind - Attachment Content Search
Search inside PDFs, PowerPoints, images, and other files in Attachments/ using macOS Spotlight (mdfind). This leverages the OS-level content index — no custom indexing needed.
Usage
/mdfind <search query> # Search all attachment content
/mdfind --type pdf <query> # Search only PDFs
/mdfind --type pptx <query> # Search only PowerPoints
/mdfind --type image <query> # Search only images (OCR-indexed)
Instructions
1. Run mdfind
Execute the appropriate search based on flags:
Default (all attachments)
mdfind -onlyin Attachments/ "<search_query>" 2>/dev/null
Filter by PDF
mdfind -onlyin Attachments/ "kMDItemContentType == 'com.adobe.pdf' && kMDItemTextContent == '*<query>*'" 2>/dev/null
If the above returns nothing, fall back to the simpler form:
mdfind -onlyin Attachments/ -name ".pdf" "<search_query>" 2>/dev/null
Filter by PPTX
mdfind -onlyin Attachments/ "kMDItemContentType == 'org.openxmlformats.presentationml.presentation'" "<search_query>" 2>/dev/null
Filter by Images
mdfind -onlyin Attachments/ "kMDItemContentType == 'public.image'" "<search_query>" 2>/dev/null
2. Present Results
Format results clearly:
## Attachment Search: <query>
Found **N** matching files
| # | File | Type | Size |
|---|------|------|------|
| 1 | [filename](path) | PDF | 2.4 MB |
| 2 | ... | ... | ... |
### Quick Actions
- Read a PDF: `/pdf-to-page <path>`
- Read a PPTX: `/pptx-to-page <path>`
- Full vault search: `/q <query>`
3. Get File Details (Optional)
For each result, get file size and type:
ls -lh "<file_path>" 2>/dev/null
Notes
mdfinduses macOS Spotlight — files must be indexed (most are by default)- Works best with text-based PDFs; scanned PDFs need OCR indexing
- For vault note content search, use
/qinstead - Results are file paths relative to the vault root
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.

mdfind is a skill published in the GitHub repository DavidROliverBA/ArchitectKB (52 stars, last pushed 6mo ago), licensed MIT. It adds 19 tokens to every session and 591 once invoked, about $0.0001 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 2026-08-30.
