pdf-explore SKILL.md skillA
pdf-explore from xuzhougeng/wisp-science is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use this skill when the user has attached a PDF, paper, report, or other document and the answer needs its content: summarize a section, compare sections, read specific pages, check the table of contents, or read a value off a figure. The `read` tool cannot parse PDF binary — python is the extraction path. Provides `pdf_pages` (pages as text or rendered PNGs, cached) and `pdf_outline` (embedded-bookmark TOC) in the persistent python kernel; load them once via the Runtime Sidecar exec line that…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Read PDFs page-by-page, not wholesale
`read` chokes on PDF binary, and pasting a 50-page document costs 40K+
tokens. The sidecar parses once into the persistent Python kernel (memory +
disk cached), after which you pull exactly the pages the question needs.
**Setup, once per session:** run the `exec(...)` line from the "Python
Runtime Sidecar" section at the end of this skill's `use_skill` output.
Definitions survive across cells until the kernel restarts. `pypdfium2` is
required (`pillow` too for image mode); if the first call raises
ImportError, follow its hint and re-run.
## Pick the entry point
| call | use for | gives |
|---|---|---|
| `pdf_outline(path)` | any structured document — start here | `[{page, heading, level}]` from embedded bookmarks, `[]` + hint when absent |
| `pdf_pages(path, pages=[...], mode="text")` | the specific pages you need | `[{page, text, n_chars}]` |
| `pdf_pages(path, mode="image", dpi=200, pages=[N])` | figures, scans | one PNG per page in `.cache/pdf-explore/`, for `view_image` |
| default `mode="auto"` | unknown file | text, auto-switching to images when pages have no text layer |

How to install
mdr add xuzhougeng/wisp-science/pdf-explore@sha256:563cf056839d2786The line at the top of this page pins the label git:20260920.11f0e27, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
