DocuPuncture prepares an Apps Script that makes targeted changes to a Google Doc, Sheet, or Slides file you already have. You review the script and run it yourself. The first run is a dry run that only logs. The script is designed to preserve surrounding structure for supported edit types.

Install in your agent

Choose a surface: Docs, Sheets, or Slides.
Download the matching zip from docupuncture.dev/install.
Put the folder where your agent reads skills, then ask for a fictional dry-run script with DRY_RUN = true.

Full host routes: docupuncture.dev/install.

Skill	Surface	Fit
`docupuncture-docs`	Google Docs	Comments, tabs, lists, partial styling.
`docupuncture-sheets`	Google Sheets	Grid and ranges. Notes and validation stay on cells you do not rewrite.
`docupuncture-slides`	Google Slides	Text and content. Layout surgery is higher risk.

The skill does not grant Google access. Chat returns the script. The live file changes only when you paste it into Extensions → Apps Script and run it.

Other installation methods

pnpm add docupuncture

Copy one folder from node_modules/docupuncture/skills/ into the agent's skills directory.

git clone https://github.com/Catalyst-Forge-LLC/docupuncture.git
# then copy skills/docupuncture-docs/  (or -sheets / -slides)

How a run works

Name the target file (URL or ID) and the intended changes.
Give the agent exact current text for anchors, or let a host Drive connector read the file if you already have one. The skill does not grant Google access.
Review the Apps Script it writes.
Open the file → Extensions → Apps Script → paste → run applyEdits.
First run is a dry run (DRY_RUN = true). Read the log, flip the flag, then run again.

The script runs as you. Missing or ambiguous anchors are logged. It never invents a location. For the showcased insert and update operations, a repeat run skips work that is already there.
