## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `astroway_chinese_tong_shu_select`

- The name "astroway_chinese_tong_shu_select" says "select": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.

- Findings: warn annotation-conflict

Description, as the server wrote it:

## Changes things (54)

### `astroway_agent_tools`

- 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
Tool definitions for an agent framework, generated from the live OpenAPI document, so the schema a model fills is the schema the endpoint validates. `format=openai` (default) returns `{ type, function }` objects you can spread straight into a chat completion; `format=anthropic` returns `{ name, description, input_schema }`. The objects carry nothing of ours: how to call each tool lives in a separate `executors` map keyed by tool name, because an unexpected key inside a vendor tool object is a 400 at their end.

[Group: Agent Platform]
[Endpoint: GET /v1/agent/tools]
[Cost: see your plan — endpoint not in the public credit manifest]
```

### `astroway_bazi_chart`

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
The four pillars with everything the classical apparatus reads off them in one call: hidden stems, na yin, the twelve stages of the day master, element balance over all eight characters, the strength verdict, symbolic stars from both reference pillars, and the branch and stem interactions. Localised by language. Pass longitude with trueSolarTime true to cut the double-hour from the sun over the birth place; the correction reaches the day and hour only, never the year and month, which turn on world instants.

Element balance across the whole chart. The `balance` object opens the branches and counts all eight characters three ways: visible, with every hidden stem, and weighted so the total stays at eight. The top-level elementCounts, dominantElement and missingElements are DEPRECATED (year and month only, four characters, branches unopened) and keep answering unchanged until 2027-09-08; the response carries RFC 8594 Deprecation and Sunset headers.
