Photutils Astronomical Photometry

Prerequisites: Python with the photutils package installed (pip install photutils). No account or API key. You supply your own astronomical images. Install "Photutils Astronomical Photometry" for me. A working guide to the Photutils package for astronomical image analysis: background estimation and subtraction, source detection, aperture photometry, PSF fitting, centroiding, and isophotal analysis. Repository: https://github.com/tondevrel/scientific-agent-skills 1. Fetch the SKILL.md file for the photutils skill (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "photutils". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. install photutils via pip if not already present, provide the images to analyze). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
