oma-brainstorm

oma-brainstorm is a skill for Claude Code, Codex from first-fluke/oh-my-agent. It costs 29 tokens per session (2,440 once invoked), scanned A, original, MIT.

A design-first brainstorming process for clarifying an idea before planning or implementation. It explores user intent, constraints, possible approaches, and trade-offs, then records an approved design.

In plain words
What is it for?
Use it to explore a new feature, compare designs, or clarify an ambiguous product idea before creating an implementation plan.
Why use it?
It helps prevent premature coding when the goal or requirements are still unclear, reducing the chance of building the wrong solution.

About the project

oh-my-agent is a harness for checking whether coding agents actually completed their work by verifying tests, required artifacts, independent reviews, and recorded decisions. It is used across multiple agent runtimes to make workflow results auditable instead of relying on an agent's own report. The catalogue add-ons provide parts of its skills, agents, hooks, MCP integrations, instructions, and plugins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

oma-brainstorm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Brainstorm - Design-First Ideation

Scheduling

Goal

Explore user intent, constraints, and alternative approaches before planning or implementation, then preserve an approved design for downstream planning.

Intent signature

  • User says they have an idea, want to brainstorm, compare approaches, explore concepts, or design before planning.
  • Request is ambiguous enough that implementation or task planning would be premature.

When to use

  • Exploring a new feature idea before planning
  • Understanding user intent and constraints before committing to an approach
  • Comparing multiple design approaches with trade-offs
  • When the user says "I have an idea" or "let's design something"
  • Before invoking /plan for complex or ambiguous requests

When NOT to use

  • Requirements are already clear and well-defined -> use oma-pm directly
  • Implementing actual code -> delegate to specialized agents
  • Performing code reviews -> use oma-qa
  • Debugging existing issues -> use oma-debug

Expected inputs

  • Early idea, ambiguous goal, product concept, design question, or set of constraints
  • Existing project context when the idea must fit a codebase or product direction
  • User preferences and approval gates

Expected outputs

  • Clarified intent and constraints
  • Viable approaches as prose briefs (scenario, mechanism, residual risk), with comparison and recommendation when alternatives aid the decision
  • Section-by-section approved design document
  • Blind-review issue list (Tier 1 resolved, Tier 2/3 resolved or explicitly deferred)
  • Saved design artifact before handoff to planning

Dependencies

  • Shared context loading, reasoning templates, clarification protocol, quality principles, and skill routing
  • Optional resources/triz-lite.md for contradiction-shaped approach seeding
  • Per-agent reviewer dispatch (e.g. qa-reviewer, architecture-reviewer) for the high-stakes blind-review escalation path
  • Downstream PM workflow for task decomposition after design approval

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
