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 5.1 | $0.00040 | $0.00422 |
| Opus 5 | $0.00020 | $0.00211 |
| Sonnet 5 | $0.00008 | $0.00084 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade C, and why
update-model scanned grade C with 2 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
compatibility: Requires curl. What it actually says
Update Model
Update an existing model's configuration on a live LiteLLM proxy.
Setup
LITELLM_BASE_URL — e.g. https://my-proxy.example.com
LITELLM_API_KEY — proxy admin key
Ask the user
- model_id (required) — if they don't have it, list models first:
curl -s "$BASE/model/info" -H "Authorization: Bearer $KEY" | python3 -c " import sys,json for m in json.load(sys.stdin).get('data',[]): print(m['model_info']['id'], m['model_name']) " - What to change — any combination of:
api_key(rotate the credential)api_base(change endpoint)api_version(Azure)model(underlying model string, e.g.azure/new-deployment)
Run
curl -s -X POST "$BASE/model/update" \
-H "Authorization: Bearer $KEY" \
-H "Content-Type: application/json" \
-d '{
"model_info": {"id": "<model_id>"},
"litellm_params": {
"api_key": "<new_key>",
"api_base": "<new_base>"
}
}'
Only include litellm_params fields being changed.
Output
Confirm the model was updated. Offer to run a test call to verify it still routes correctly.
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.

update-model is a skill published in the GitHub repository BerriAI/litellm-skills (84 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 422 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
