  • Works in 4 steps: Understanding → Exploration → Design Presentation → …

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Brainstorming is an agent skill from sandgardenhq/sgai. Interactive idea refinement using Socratic method to develop fully-formed designs. When your human partner says "I've got an idea", "Let's make/build/create", "I want to implement/add", "What if we". When starting design for complex feature. Before writing implementation plans. When idea needs refinement and exploration. ACTIVATE THIS AUTOMATICALLY when your human partner describes a feature or project idea - don't wait for /brainstorm command.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `ABOUT.md`).

It sits in Agent Workflows, covering Brainstorming. The repository describes itself as: Sandgarden AI Software Factory.

When your agent uses it

  • Tasks that involve Brainstorming

Example prompts

  • “ve got an idea”
  • “s make/build/create”
  • “I want to implement/add”
  • “/brainstorming”

Workflow steps

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

  1. Understanding
  2. Exploration
  3. Design Presentation
  4. Validation Criteria

What it can do on your machine

Read from SKILL.md and the folder at commit 9efbb7b. 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

Brainstorming loads about 1.4k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 538 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 538 words (~1,354 tokens).

“Transform rough ideas into fully-formed designs through structured questioning and alternative exploration.”
