Tasks that involve PDF

Example prompts

“/add-pdf-reader”

Requirements

Node.js
Docker

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Pre-flight
Apply Code Changes
Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 1395af4. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
- npm
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Add PDF Reader loads about 767 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 290 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~37
When it runs · the whole SKILL.md, loaded when a task matches: ~767

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

name: add-pdf-reader
description: Add PDF reading to ClaudeClaw agents. Extracts text from PDFs via pdftotext CLI. Handles WhatsApp attachments, URLs, and local files.

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 agent/skills/pdf-reader/pdf-reader exists — skip to Phase 3 if already applied
Confirm WhatsApp is installed first (skill/whatsapp merged). This skill modifies WhatsApp channel files.

Phase 2: Apply Code Changes

Ensure WhatsApp fork remote

bash

git remote -v

If whatsapp is missing, add it:

bash

git remote add whatsapp https://github.com/qwibitai/claudeclaw-whatsapp.git

Merge the skill branch

bash

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:

agent/skills/pdf-reader/SKILL.md (agent-facing documentation)
agent/skills/pdf-reader/pdf-reader (CLI script)
poppler-utils in src/runtimes/docker/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

bash

npm run build
npx vitest run src/channels/whatsapp.test.ts

Rebuild container

bash

./src/runtimes/docker/build.sh

Service name: Derived from the directory name: com.claudeclaw.<dirname> (macOS) / claudeclaw-<dirname> (Linux). For example, if cwd is my-assistant, the service is com.claudeclaw.my-assistant. Determine the correct service name before running service commands below.

Restart service

bash

launchctl kickstart -k gui/$(id -u)/com.claudeclaw  # macOS
# Linux: systemctl --user restart claudeclaw

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

bash

tail -f logs/claudeclaw.log | grep -i pdf

Look for:

Downloaded PDF attachment — successful download
Failed to download PDF attachment — media download issue

Troubleshooting

Agent says pdf-reader command not found

Container needs rebuilding. Run ./src/runtimes/docker/build.sh and restart the service.

PDF text extraction is empty

The PDF may be scanned (image-based). pdftotext only handles text-based PDFs. Consider using the agent-browser to open the PDF visually instead.

WhatsApp PDF not detected

Verify the message has documentMessage with mimetype: application/pdf. Some file-sharing apps send PDFs as generic files without the correct mimetype.
