arxiv-catchup SKILL.md skillA
arxiv-catchup from tomzx/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tomzx/agents/arxiv-catchup@git:20261007.b35fc4bPins git:20261007.b35fc4b in mdr.lock. Pin the fingerprint instead.

Fetches new arXiv cs.AI papers published since the last processed date, processes each paper's HTML version via the arxiv-article skill, and advances the date checkpoint. Use when the user says /arxiv-catchup, catch up on arXiv, or wants to read recent AI papers.
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
# arXiv Catchup
Fetches cs.AI papers from arXiv published since the last checkpoint date, calls **arxiv-article** for each (via parallel subagents), then advances the checkpoint to today.
## Prerequisites
`ARXIV_DIRECTORY` must be set to the directory where archived articles are stored (e.g., `~/arxiv-articles`).
If the variable is unset, stop and ask the user to set it.
```bash
echo "${ARXIV_DIRECTORY:?ARXIV_DIRECTORY is not set}"
```
## State file
`~/.arxiv-catchup/state.yaml`
```yaml
last_date: "YYYY-MM-DD"
```
- If the file does not exist, ask the user what start date to use before proceeding.
- The date is always in `YYYY-MM-DD` format.
- After all articles are processed, update the file with today's date.
## Steps
### 1. Read the last-processed date
```bash
mkdir -p ~/.arxiv-catchup
cat ~/.arxiv-catchup/state.yaml 2>/dev/null
```
If the file does not exist or is empty, ask the user:
> "No catchup state found.
> From what date should I start?
> (YYYY-MM-DD)"
Wait for the user's answer, then use it as `last_date`.
### 2. Fetch the catchup page
```bash
curl -L --silent --max-time 60 \
-A "Mozilla/5.0 (compatible; research-bot/1.0)" \
…Read the whole file at its exact version.
How to install
mdr add tomzx/agents/arxiv-catchup@sha256:f847f8fe8e156655The line at the top of this page pins the label git:20261007.b35fc4b, 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.
