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.

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 | $0.00190 | $0.00190 |
| Opus 5 | $0.00095 | $0.00095 |
| Sonnet 5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
credentials-and-docs 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 yesterday.
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.
What it actually says
- Never print, echo, or commit
MODELLIX_API_KEYor profile secrets. - Prefer session-only credentials; persist only when the user explicitly asks (
modellix-cli auth login/initpreferred). - Discover existing key/env/profile before asking again.
- Do not invent model slugs from doc filenames (decimals matter, e.g.
bytedance/seedance-2.0-mini-t2v). Verify viamodel describe, Docs MCP, orllms.txt. - Product/API/schema docs: prefer Docs MCP (
https://docs.modellix.ai/mcp) when connected; elsedocs_url/llms.txt. - CLI flags and command syntax: trust npm
modellix-cli/--helpover website CLI pages (docs can lag).
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.

credentials-and-docs is a cursor rule published in the GitHub repository Modellix/modellix-plugin (1 stars, last pushed 20d ago), licensed MIT. It adds 190 tokens to every session, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
