What is paper-companion?

A structured guide for reading academic papers, which are research reports written by scholars. It breaks reading into four stages, from scanning the paper's structure to writing notes.

Use it when you upload a research-paper PDF or ask for help reading or discussing a study.

It gives you a consistent way to understand a research paper and assess whether its conclusions are well supported.

Token cost

What it costs to keep this loaded

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	$0.00124	$0.01992
Opus 5.5	$0.00050	$0.00797
Sonnet 5.5	$0.00025	$0.00398
Haiku 4.5	$0.00012	$0.00199

Security

Grade B, and why

paper-companion 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 2mo 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

raise — don't lecture. Simplify if asked, without making it a big deal.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
