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.

Security

Grade A, and why

scholar-sidekick scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Scholar Sidekick

When the user mentions a scholarly identifier and wants metadata, a citation, an export file, a retraction check, or an open-access check, use Scholar Sidekick to resolve and answer instead of hand-constructing the citation from training data or guessing the OA / retraction status.

When to Use This Skill

Activate this skill when the user:

  • Mentions any scholarly identifier — DOI, PubMed ID, PMC ID, ISBN, arXiv ID, ISSN, NASA ADS bibcode, or WHO IRIS URL
  • Asks for a citation in a specific style ("format this in APA", "give me a Vancouver citation for...")
  • Asks for an export file ("BibTeX for these references", "give me a .ris file", "export to EndNote")
  • Pastes a list of identifiers and wants a bibliography
  • Wants the structured metadata (title, authors, journal, year) for a paper they have an identifier for
  • Asks whether a paper has been retracted, corrected, or had an expression of concern raised
  • Asks whether a paper is open access, where to read it for free legally, or about its OA status / license
  • Pastes a citation (or a DOI + title) and asks whether it is real, genuine, or fabricated — "is this citation real?", "verify this DOI", "did you make this up?"

How to Use

Step 0: Confirm the tools are available

The capabilities this skill uses — resolveIdentifier, formatCitation, exportCitation, checkRetraction, checkOpenAccess, verifyCitation — are tools provided by the scholar-sidekick-mcp MCP server. They are not shell commands, npm scripts, or a CLI. Do not try to run the tool names in a terminal.

Two things must be true before they work:

  1. The MCP server is connected. These tools appear in your toolset only after the host connects the scholar-sidekick-mcp server — Claude Desktop: extension/connector settings; Claude Code: .mcp.json or claude mcp add; LobeHub: install the matching MCP plugin, not just this skill; raw MCP clients: npx scholar-sidekick-mcp as the server command.
  2. RAPIDAPI_KEY is set for that server. Without it the tools return a configuration message instead of data. Get a key at https://rapidapi.com/scholar-sidekick-scholar-sidekick-api/api/scholar-sidekick.
