## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-16 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 27 to 30. That category is still filling its 30-day observation window: 8 days of observed history at the previous scan, 9 at this one. The score rises as the window fills, whether or not the server changes.

First indexed and scored.

## MCP tools (3)

### `get_price` (~62 tokens)

Current list price for one LLM, with the source and the date it was last confirmed. Returns disputed=true when two sources disagree.

Input parameters:

- `model_name` (string, required): Model id or name, e.g. gpt-5 or "Claude Opus 5".

### `estimate_cost` (~182 tokens)

What a described workload actually costs per month on each model. Accounts for conversation history compounding, cache writes, long-context tiers and reasoning tokens. Use this instead of multiplying prices by hand.

Input parameters:

- `cached_input_share` (number): 0-1. Default 0.
- `conversations_per_day` (number): Default 1000.
- `models` (array, required): Models to compare, up to about 8.
- `output_tokens` (number): Typical reply. Default 350.
- `reasoning_multiplier` (number): Bill output at this multiple. Default 1.
- `system_tokens` (number): System prompt size. Default 800.
- `turns` (number): Turns per conversation. Default 4.
- `use_batch_api` (boolean): Apply batch discounts. Default false.
- `user_tokens` (number): Typical user message. Default 150.

### `find_cheaper` (~112 tokens)

Cheaper models that score at or above the given one on capability, costed on the same workload. Returns candidates to test, not a recommendation.

Input parameters:

- `conversations_per_day` (number)
- `min_capability` (number): 0-100. Defaults to the given model’s score.
- `model` (string, required): The model currently in use.
- `output_tokens` (number)
- `system_tokens` (number)
- `turns` (number)
- `user_tokens` (number)
