## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `sky_window`

- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
This tool looks up a deterministic rules engine. Same day → same answer. Do not invent pillars or fortune claims. Call when the user asks 未来两周有什么天象 / 新月哪天 / 日食哪天 / 接下来有没有逆行 / what sky events are coming. Lists dated L1 sky marks (new/full moon, eclipse, ingress, stations). Public · local · no API key. Max span 45 days. Preview ≠ prediction.
```

## Changes things (9)

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

### `activity_window`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
This tool looks up a deterministic rules engine. Same day → same answer. Do not invent pillars or fortune claims. Call when the user asks 今天什么时候适合运动 / 今天哪个时辰适合深工 / 什么时候开会 / 什么时候练 / 什么时候发版 / 什么时候该休息 / activity window / when to exercise. Maps month posture × twelve hours × body load to 2–3 clock windows for task=deep_work|train|meet|ship|rest. Windows are suggested slots, not a guarantee. Not meds, not glucose, not a diagnosis. Public · local · no API key. Preview ≠ prediction.
```

### `body_rhythm`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
This tool looks up a deterministic rules engine. Same day → same answer. Do not invent pillars or fortune claims. Call when the user asks 今晚要不要提前睡 / 今天该不该加练 / 现在这个时辰适不适合动 / body energy / train or rest. Public body-energy rehearsal from solar term + hour + month posture × sky tightness. Not a diagnosis. Adjust ≠ infuse energy. Public · local · no API key. Preview ≠ prediction.
```

### `energy_adjust`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text

Same engine, two seats: personal (sleep/load) or org (window push vs hold). Not HR scoring, not medical treatment. Public · local · no API key. Preview ≠ prediction.

Call when the user asks 这个月势能怎么样 / 这个月该打磨还是该收 / 这个月哪天发布 / 这个月节奏怎么样 / 流月基调 / 做不做某事 / 哪几天适合上线 / which days to publish. First line is the #be time atom (keep 干支 in Chinese). Then this month’s fold year (same pillar), baseline tone, and dated sky marks. Always surface the fold-year line and ask what they lived that year. Public · local · no API key. Preview ≠ prediction.
```

### `personal_day`

- Nothing in its name or description says what it does, so it is counted as a write.

Personalized: day-master vs today's stem (十神) + optional hour pillar. Requires BALANCE_API_KEY + birth profile. Empty key → error personal_timetable_requires_key; use free tools instead. Not a fortune verdict.

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

Do not mention marriage, burial, or god directions. Public · local · no API key. Preview ≠ prediction.
```

### `people_roster`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

Call when the user names a person, asks 这个人是谁 / 西交和宁波是不是同一个 / 花名册 / people roster, or before telling a story that involves named people. Pass people=[{name, relation, id?}] from what the user just said. If empty, ask the user to name people (name + one-line relation) — do not invent a biography. Optional env PEOPLE_ROSTER_JSON when the user keeps a local roster. Not L1. Public · no API key.
```
