## Quality 73/100 (new)

### protocol: 75 (weight 25)

- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_fertilizer_price (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_fertilizer_history (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_livestock_price (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,910 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 0 of the 7 days needed

### dependencies: n/a (weight 15)
