What it does
PDF Text Replace is an agent skill from instavm/coderunner. Replace text in fillable PDF forms by updating form field values. This skill should be used when users need to update names, addresses, dates, or other text in PDF form fields.
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/replace_text_in_pdf.py`).
It sits in Documents & Office, covering PDF. It works with Model Context Protocol and OpenAI. The repository describes itself as: A local sandbox for your AI agents. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve PDF
Example prompts
- “/pdf-text-replace”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- input_pdf - Path to input PDF file
- search_text - Text to search for in form fields
- replace_text - Text to replace with
- output_pdf - Path to save the updated PDF
What it can do on your machine
Read from SKILL.md and the folder at commit e8a4b58. 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 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
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 Text Replace loads about 536 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 223 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.
