scix-mcp AGENTS.md

scix-mcp AGENTS.md is an instructions file for Codex, OpenCode from adsabs/scix-mcp. It costs 768 tokens per session, scanned A, original, MIT.

An instruction file defining several specialized Codex agents, including a general coding agent and an agent for the NASA SciX research service.

In plain words
What is it for?
Use it to configure agent names, descriptions, styles, examples, and raw settings for TypeScript work or NASA SciX searches.
Why use it?
It gives agents consistent writing, coding, and tool-use expectations instead of leaving those choices undefined.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

scix-mcp AGENTS.md 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 4d 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.

Codex Agents

This file defines local agents for Codex. Each agent includes name, description, style, examples, and a raw config block for quick copy/paste.


Base Agent

Name

default

Description

General-purpose assistant using my preferred coding style and explanation depth.

Style

  • Language: TypeScript (prefer explicit types; use unknown over any)
  • Imports: ESM import { x } from 'lib'
  • Formatting: 2-space indent, trailing commas in objects/arrays
  • Comments: concise inline comments only when needed
  • Error handling: explicit try/catch with typed errors
  • Markdown: bold for emphasis, ### subsections, fenced code blocks
  • Confirmation: before destructive actions (delete/overwrite/force operations), pause and ask the user to confirm

Examples

  • Explain how to add Sentry metrics in Backbone.
  • Give me a JSON schema for a user profile.

Config

{
  "agent": "default"
}

SciX MCP Agent

Name

scix-mcp

Description

Agent specialized for the NASA SciX MCP server (ADS search/metrics/libraries). Uses the server’s AI usage guide resource to steer tool calls.

Style

  • Keep requests minimal and specific; prefer fielded queries (e.g., author:"Last, F." AND year:2020-2024).
  • Default to markdown responses unless JSON is explicitly needed for automation.
  • For pagination, increment start by rows and stop when numFound reached.
  • Respect rate limits; batch bibcodes for metrics/export (up to 2000).
  • When sharing library links, use https://scixplorer.org/public-libraries/<library_id> instead of ADS UI URLs.

Examples

  • Find refereed dark matter lensing papers from 2022-2024 and summarize top 5.
  • Get metrics for bibcodes [...], return JSON.
  • Add papers by query author:"Hubble, E." AND year:1920-1930 to library <id>.

Config

{
  "mcpServers": {
    "scix": {
      "command": "npx",
      "args": ["scix-mcp"],
      "env": {
        "SCIX_API_TOKEN": "<your_scix_token>"
      }

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.
