No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `heart_cast`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Deterministically cast a YOWAYOW Mind-Key hexagram from six evidence-grounded root/body/outcome positions. Use after an autonomous agent has researched a concrete action choice, structural diagnosis, experiment, or macro-structure question. Submit current facts and their manifestation verdicts; never submit yin/yang lines or a desired hexagram. The tool returns cast_ready, needs_evidence, or out_of_scope. It uses no LLM, no random/time casting, and never falls back to traditional liuyao. Do not use for fortune, luck, hidden facts, random outcomes, or as a substitute for high-stakes professional judgment.
```

### `heart_fit`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this zero-AI preflight before heart_cast when the original question is ambiguous or unstructured. It rejects ordinary fact lookups, pure prophecy, fortune, hidden facts, traditional liuyao, and high-stakes professional replacement. It returns research_required, needs_detail, or out_of_scope, plus the autonomous agent's next step. A needs_detail response means the agent should extract or research objective, options, constraints, success criteria, and current evidence; it does not require a human reply when authorized sources are available.
```
