A routing and guidance tool for Ai2 Asta, a research service based on the Semantic Scholar academic-paper database. It helps choose workflows for finding papers, following citations, and discovering authors.

Searching academic papers, tracing citations, and finding authors through the Semantic Scholar corpus.

It helps turn research requests into suitable searches and warns about common mistakes. This reduces the need to know the service's tools and search patterns in advance.

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	$0.00106	$0.03860
Opus 5.5	$0.00042	$0.01544

Security

Grade B, and why

asta 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Codex CLI: add `[mcp_servers.asta] url = "https://asta-tools.allen.ai/mcp/v1"` and `env_http_headers = { "x-api-key" = "ASTA_API_KEY" }` to `~/.codex/config.toml`.

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.
