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

sansfiction-catalog scanned grade A 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SansFiction

SansFiction is a digital library for books, collections, reading journals, and discovery. This skill drives its public REST API (/api/v1). An MCP server exposing the same capabilities is also available at /api/mcp for MCP-native clients — both accept the same bearer token.

Base URL: https://sansfiction.com

Authentication

Public catalog endpoints need no auth. Personal library endpoints require a bearer token:

Authorization: Bearer sf_mcp_xxxxxxxxxxxxxxxxxxxxxxxx

A signed-in user generates a token at https://sansfiction.com/docs/agents. Never ask the user for a password — only a token. On 401, ask for a fresh one.

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.
