What it does

PDF Form Filler is an agent skill from sundial-org/awesome-openclaw-skills. Fill PDF forms programmatically with text values and checkboxes. Use when you need to populate fillable PDF forms (government forms, applications, surveys, etc.) with data. Supports setting text fields and checkboxes with proper appearance states for visual rendering.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `README.md`, `pdf_form_filler/__init__.py` and `pdf_form_filler/fill_pdf_form.py`).

It sits in Documents & Office, covering PDF. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.

When your agent uses it

  • You need to populate fillable PDF forms (government forms
  • Etc.) with data

Example prompts

  • “/pdf-form-filler”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Opens the PDF template
  2. Iterates through form fields
  3. Sets values for matching field names
  4. Handles checkboxes by setting both /V (value) and /AS (appearance state)
  5. Saves the filled PDF

What it can do on your machine

Read from SKILL.md and the folder at commit b80cde2. 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

    Ships script files (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

PDF Form Filler loads about 1.1k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 340 words (~1,127 tokens).

“Programmatically fill PDF forms with text values and checkboxes. Uses pdfrw to set form field values while preserving appearance streams for proper PDF viewer rendering.”
