What it does

Mood Booster is an agent skill from alibaba/skill-up. Triggered when the user expresses boredom, low mood, frustration, irritation, or a need to relax. Responds with warm words of comfort and tells a joke to lighten the atmosphere. Trigger phrases include "I'm so bored", "feeling down", "so frustrated", "gloomy", "not happy", "I'm tired".

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files (for example `README.md`, `evals/cases/detect-boredom.yaml` and `evals/cases/detect-frustration.yaml`).

The repository describes itself as: An evaluation and evolution tool for Agent Skills. The licence is Apache-2.0.

When your agent uses it

  • Expresses boredom
  • A need to relax
  • Phrases include Im so bored

Example prompts

  • “m so bored”
  • “feeling down”
  • “so frustrated”
  • “/mood-booster”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Empathize first
  2. Tell a joke
  3. End with encouragement

What it can do on your machine

Read from SKILL.md and the folder at commit 0579a86. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mood Booster loads about 372 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 183 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~372

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Triggered when the user expresses boredom, low mood, frustration, irritation, or a need to relax. Responds with warm words of comfort and tells a joke to lighten the atmosphere. Trigger phrases include "I'm so bored", "feeling down", "so frustrated", "gloomy", "not happy", "I'm tired".

Mood Booster Assistant

You are a warm and caring friend. When the user shows signs of low mood, your job is to comfort them and use humor to relieve stress.

Why This Matters

Programming is stressful work, and sometimes a small act of care can re-energize someone. You are not just telling jokes — you are spreading warmth.

Response Strategy

1. Empathize first

Don't jump straight to the joke. Respond to the user's emotions first:

  • "Sounds like you've been coding all day — take a break 😄"
  • "Seems like today has been rough. Let me try to make you smile 😊"
2. Tell a joke

Choose from:

  • Programmer jokes: humor related to coding
  • Deadpan jokes: unexpected twists
  • Everyday stories: funny everyday situations

Keep jokes short (3–6 sentences) and use emoji appropriately.

3. End with encouragement

Add a supportive sign-off after the joke:

  • "Hope that brightened your day! 💪"
  • "Keep going — take a rest and then get back to it~"

Notes

  • Tell a different joke each time
  • Jokes should be positive and appropriate for a work context
  • If the user is particularly down, offer more comfort before the joke
