Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00153 | $0.01454 |
| Opus 5.5 | $0.00061 | $0.00582 |
| Sonnet 5.5 | $0.00031 | $0.00291 |
| Haiku 4.5 | $0.00015 | $0.00145 |
Grade B, and why
read-paper scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
**Not all files may be present.** If a file is missing (e.g. no `kimi.md` or `paper.md`), skip it gracefully and work with what's available. Never tell the user a file "should" exist — just use alternative sources. For e How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reading Paper Folders
Paper folders are exported by ZoFiles from Zotero. Each folder is named {arxivId} - {title} and contains structured files about one academic paper.
Paper Library Location
The paper library is at:
<FILL_IN: ask the user for their ZoFiles export root path, then update this file>
First-use setup: If the path above says
<FILL_IN...>or doesn't exist, ask the user: "What's the path to your ZoFiles paper library?" Then:
- Update the path above
- Run
scan-library.shto populate the directory snapshot (see Updating the Directory Snapshot)
Directory Structure
The library mirrors Zotero's collection hierarchy. Collections become directories, sub-collections become subdirectories, and paper folders sit at the leaves.
Key patterns:
Allin/directories appear when a collection has subcollections — contains all papers from that collection and every descendant (flat view of the entire subtree).- Paper folders are named
{arxivId} - {title}(e.g.2512.18832 - From Word to World...). - Find by arXiv ID: glob
**/2512.18832*from the library root. - Browse a topic: list the corresponding collection directory.
- See all papers: glob
**/paper.mdor**/arxiv.idrecursively.
Current Library Snapshot
<FILL_IN: run the scan script below to populate this snapshot>
Use this snapshot to quickly orient yourself when the user asks about topics, collections, or paper counts — no need to scan the filesystem each time.
Updating the Directory Snapshot
When the user asks to update the directory structure (e.g. "更新目录", "update directory", "refresh library"):
bash .claude/skills/read-paper/scripts/scan-library.sh "<library_root>"
Then replace the content between <!-- AUTO-GENERATED --> and <!-- END AUTO-GENERATED --> markers in this file with the new output (wrapped in a ```code block), and update the<!-- Last updated: ... --> date.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

read-paper is a skill published in the GitHub repository X1AOX1A/ZoFiles (40 stars, last pushed 5mo ago), licensed MIT. It adds 153 tokens to every session and 1,454 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
