A skill your agent uses when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning…

  • Works in 3 steps: Understanding → Exploration → Design Presentation
  • Developing anything
  • SKILL.md covers Overview, Quick Reference, The Process and Research Agents, plus 8 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Brainstorming is an agent skill from ed3dai/ed3d-plugins. Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Brainstorming, Planning and Tutoring and explanations. The repository describes itself as: Ed's repo of Claude Code plugins, centered around a research-plan-implement workflow. Only a tiny bit cursed. If you're lucky.

When your agent uses it

  • Developing anything
  • Before writing code
  • Implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning
  • Alternative exploration

Example prompts

  • “/brainstorming”

Workflow steps

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

  1. Understanding
  2. Exploration
  3. Design Presentation

What it can do on your machine

Read from SKILL.md and the folder at commit 0c90f4b. 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 (its code samples are dot).

    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 4.3k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 1,793 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,793 words (~4,308 tokens).

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