What it does

Evanflow Brainstorming is an agent skill from evanklem/evanflow. Clarify intent, propose 2-3 approaches, embedded grill to stress-test the chosen path. Use before any creative work — new features, components, behavior changes, design questions. Mockup-only requests use mockup quick-mode (no spec/plan ceremony).

Its SKILL.md is about 1k 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 and Load testing. The repository describes itself as: A TDD-driven iterative feedback loop for software development. 16 cohesive Claude Code skills walk an idea from brainstorm → plan → execute → iterate, with checkpoints throughout.

When your agent uses it

  • Tasks that involve Load testing

Example prompts

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Quick context check. Skim relevant files, recent commits, and any referenced docs. Do NOT exhaustively explore — just enough to ground the…
  2. Scope check. If the request describes multiple independent subsystems, flag it and propose decomposition before going further. Don't…
  3. Ask clarifying questions one at a time. Multiple-choice when possible (use AskUserQuestion). Focus on purpose, constraints, success…
  4. Propose 2–3 approaches with trade-offs and your recommendation as option (a). Lead with "here's what I'd do and why."
  5. Embedded Grill (see below) — stress-test the chosen approach before committing.
  6. Present the design in sections sized to their complexity. Get explicit approval after each section.
  7. Decide: spec doc, straight to plan, or just go.

What it can do on your machine

Read from SKILL.md and the folder at commit c9ae21f. 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

Evanflow Brainstorming loads about 1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 532 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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 532 words (~1,028 tokens).

“See evanflow meta-skill. Key terms used here: deep modules, deletion test, mockup quick-mode, grill.”
