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 | $0.00037 | $0.00672 |
| Opus 5 | $0.00018 | $0.00336 |
| Sonnet 5 | $0.00007 | $0.00134 |
| Haiku 4.5 | $0.00004 | $0.00067 |
Grade A, and why
add-pdf-reader 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 7d 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.
This is a copy
86% identical to add-pdf-reader — 34 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add PDF Reader
Adds PDF reading capability to all container agents using poppler-utils (pdftotext/pdfinfo). PDFs sent as WhatsApp attachments are auto-downloaded to the group workspace.
Phase 1: Pre-flight
- Check if
container/skills/pdf-reader/pdf-readerexists — skip to Phase 3 if already applied - Confirm WhatsApp is installed first (
skill/whatsappmerged). This skill modifies WhatsApp channel files.
Phase 2: Apply Code Changes
Ensure WhatsApp fork remote
git remote -v
If whatsapp is missing, add it:
git remote add whatsapp https://github.com/qwibitai/nanoclaw-whatsapp.git
Merge the skill branch
git fetch whatsapp skill/pdf-reader
git merge whatsapp/skill/pdf-reader || {
git checkout --theirs package-lock.json
git add package-lock.json
git merge --continue
}
This merges in:
container/skills/pdf-reader/SKILL.md(agent-facing documentation)container/skills/pdf-reader/pdf-reader(CLI script)poppler-utilsincontainer/Dockerfile- PDF attachment download in
src/channels/whatsapp.ts - PDF tests in
src/channels/whatsapp.test.ts
If the merge reports conflicts, resolve them by reading the conflicted files and understanding the intent of both sides.
Validate
npm run build
npx vitest run src/channels/whatsapp.test.ts
Rebuild container
./container/build.sh
Restart service
launchctl kickstart -k gui/$(id -u)/com.nanoclaw # macOS
# Linux: systemctl --user restart nanoclaw
Phase 3: Verify
Test PDF extraction
Send a PDF file in any registered WhatsApp chat. The agent should:
- Download the PDF to
attachments/ - Respond acknowledging the PDF
- Be able to extract text when asked
Test URL fetching
Ask the agent to read a PDF from a URL. It should use pdf-reader fetch <url>.
Check logs if needed
tail -f logs/nanoclaw.log | grep -i pdf
Look for:
Downloaded PDF attachment— successful downloadFailed to download PDF attachment— media download issue
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.
