Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00016 | $0.00299 |
| Opus 5.5 | $0.00006 | $0.00120 |
| Sonnet 5.5 | $0.00003 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
doctor 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 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.
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
Diagnose the Modellix setup. Optional profile: $ARGUMENTS
Read-only: never submit a paid task from this command.
- Run the packaged preflight so a missing/older CLI is refreshed from public npm before doctor:
python3 skills/modellix-design/scripts/preflight.py --json
Add --profile $ARGUMENTS when a profile was given. MODELLIX_CLI_AUTO_UPDATE=0 pins the installed version; otherwise update failure safely retains an existing CLI or reports the REST fallback.
- Read the report: Node.js version, key source, API connectivity, key validity, balance.
doctornever prints the key itself. - If no credential resolves, follow the API key lifecycle in
skills/modellix-design/SKILL.md: discover the session envMODELLIX_API_KEYand saved profiles first, ask the user only when nothing is available, and keep it session-only unless they ask to persist (modellix-cli auth login). - If the CLI cannot be installed, say so and note that the REST fallback in
skills/modellix-design/references/rest-playbook.mdneedsMODELLIX_API_KEY. - Summarize what passed, what failed, and the single next action. Never echo the key.
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.

doctor is a command published in the GitHub repository Modellix/modellix-plugin (1 stars, last pushed 2d ago), licensed MIT. It adds 16 tokens to every session and 299 once invoked, about $0.0001 per session on Opus 5.5. 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.
