Excretion Tracker（排泄记录）

This skill is chat-only: always log via the bundled CLI and store data locally.

0) Safety / scope

• No medical diagnosis.
• If the user reports blood in stool/urine, severe pain, fever, or symptoms lasting >24–48h, recommend professional medical advice.

1) What to collect (required vs optional)

New: Attempt (no output)

If the user reports abdominal pain / urge and no pee/poop produced (e.g., “蹲了20分钟都没有产出”), log an attempt event with:

• start time
• duration
• pain
• intent: poop | pee | unknown
• notes

Do not force color/Bristol when there was no output.

Required for every log

• type: pee | poop | attempt (no output)
• start_at: timestamp (default: now)
• duration_sec: integer (if unknown, ask)
• pain: 0–3 (0 none, 1 mild, 2 moderate, 3 severe)

Color requirement

• For pee and poop: color is required
• For attempt (no output): color is not required

Poop-only

• bristol: 1–7 (ask if poop)

Optional

• notes: short free text

2) Bristol stool scale (what it is)

Bristol（布里斯托大便分类）把便便形态分为 1–7：

• 1–2：偏干硬（便秘倾向）
• 3–4：相对正常
• 5–7：偏稀（腹泻倾向）

If user doesn’t know, ask 1 question:

• “更像：1/2（很硬成颗粒） 3/4（成形） 5/6/7（软烂到水样）？”

See details: references/bristol.md.

3) Color options (display to user in Chinese; English in Title Case)

Pee color

• Clear（透明）
• Pale Yellow（浅黄）
• Yellow（黄色）
• Dark Yellow（深黄）
• Amber（琥珀色）
• Red（红）
• Brown（褐）
• Other（其他）

Poop color

• Normal Brown（正常棕）
• Light Brown（浅棕）
• Yellow（黄）
• Green（绿）
• Black（黑）
• Red（红）
• Pale（偏浅/灰白）
• Other（其他）

Internal storage can still use snake_case enums, but never show snake_case to the user.

4) Chat-only flow (includes optional card feedback)

When the user says they went to the bathroom:

1) Determine type (pee/poop). If unclear, ask.

2) Ask only missing required fields in the user's language (Chinese).

• If you need to show any English options, format them in Title Case (no underscores).

3) Ask for:

• start time (if not specified)
• duration (minutes/seconds)
• color
• pain (0–3)
• for poop: bristol (1–7)

4) Log the event via CLI: excretion log ....

5) Optional visual card (SOP):

• Cards are disabled by default.
• If the user enables cards, detect whether nano-banana-pro is installed.
• If installed: follow references/card_sop.md to generate a consistent cute 3:4 card using nano-banana-pro and send it.
• If not installed: skip silently (no extra questions).

Enable/disable:

• Enable: excretion config set card_enabled 1
• Disable: excretion config set card_enabled 0

Note: This skill intentionally ships no image-generation scripts. The agent executes the SOP by invoking nano-banana-pro only when cards are enabled.

If user says “刚刚/刚才” → use now.

If user provides duration like “2分钟” → convert to seconds.

5) Commands to run

• Log pee:
• excretion log pee --start-at "..." --duration-sec 60 --color yellow --pain 0 --notes "..."

• Log poop:
• excretion log poop --start-at "..." --duration-sec 180 --color normal_brown --pain 1 --bristol 4 --notes "..."

• Show weekly summary:
• excretion week

• Set reminder threshold (hours):
• excretion config set poop_remind_hours 24

6) Weekly summary (what to send)

Include:

• Poop frequency + avg interval
• Bristol distribution (counts)
• Poop pain average
• Pee frequency (day vs night)
• Red-flag events count (blood/pain>=3)
• “Not medical advice” note

7) Files

• CLI: scripts/excretion.py
• Bristol reference: references/bristol.md
• (Optional) Card generation SOP: references/card_sop.md (uses nano-banana-pro if installed; otherwise skip)
