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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.00588 |
| Opus 5.5 | $0.00033 | $0.00235 |
| Sonnet 5.5 | $0.00016 | $0.00118 |
| Haiku 4.5 | $0.00008 | $0.00059 |
Grade A, and why
pdf-tools 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.
What it actually says
PDF Tools
Local, keyless PDF manipulation. Detect what's installed and use it; nothing leaves the machine.
Step 0 — Detect tools
- macOS / Linux:
command -v qpdf pdftk pdftotext pdfinfo pdftoppm img2pdf gs 2>/dev/null - Windows:
Get-Command qpdf, pdftk, pdftotext -ErrorAction SilentlyContinue
Install hints: brew install qpdf poppler img2pdf ghostscript / apt install qpdf poppler-utils img2pdf ghostscript / choco install qpdf.
Common operations
Merge (qpdf preferred, pdftk fallback):
qpdf --empty --pages a.pdf b.pdf -- merged.pdf
pdftk a.pdf b.pdf cat output merged.pdf
Split / extract pages:
qpdf in.pdf --pages in.pdf 2-5 -- pages_2_5.pdf
pdftk in.pdf cat 1 3 5 output odd.pdf
Rotate:
qpdf in.pdf out.pdf --rotate=+90:1-z
Compress (Ghostscript):
gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -o small.pdf in.pdf
Extract text (then summarize/answer with @read):
pdftotext -layout in.pdf out.txt
PDF → images / images → PDF:
pdftoppm -png -r 150 in.pdf page
img2pdf img1.png img2.jpg -o out.pdf
Inspect: pdfinfo in.pdf (page count, size, encryption).
Rules
- Work on copies; never overwrite the user's source PDF unless told to.
- For scanned/image PDFs with no text layer, hand off to the
ocrskill. - Report output path + page count after each operation.
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.

pdf-tools is a skill published in the GitHub repository diillson/chatcli (94 stars, last pushed today), licensed Apache-2.0. It adds 82 tokens to every session and 588 once invoked, about $0.0003 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 2026-09-03.
