Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00038 | $0.02225 |
| Opus 5 | $0.00019 | $0.01112 |
| Sonnet 5 | $0.00008 | $0.00445 |
| Haiku 4.5 | $0.00004 | $0.00222 |
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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
/planfor complex or ambiguous requests
When NOT to use
- Requirements are already clear and well-defined -> use
oma-pmdirectly - 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
- Two or three approaches as prose briefs (scenario, mechanism, residual risk) plus a comparison matrix and recommended option
- 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.mdfor 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
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

oma-brainstorm is a skill published in the GitHub repository first-fluke/fullstack-starter (222 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 2,225 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
background-task
Add or modify work that runs outside the request/response cycle — emails, document ingestion, webhooks, cleanups, scheduled jobs. Use when something is slow or fire-and-forget, or when adding a periodic/cron task. This project's queue is {{ cookiecutter.backgroundtasks }}.
frontend-feature
Build a new page, view, or data-driven feature in the Next.js frontend. Use when adding a route under the dashboard/marketing area, wiring UI to a backend endpoint, adding client state, or creating a localized page. Covers App Router, data fetching, Zustand stores, and i18n.
pytest-suite
Write or extend the backend test suite following this project's conventions. Use when adding tests for a new service/route/repository, when coverage is missing, or when asked to test a feature. Knows the mocked-session + httpx AsyncClient setup so tests run with no database.
rag-knowledge
Work with the RAG knowledge base — ingest documents, run semantic search, manage collections, or add a sync source/connector (Google Drive, S3). Use when populating or debugging the knowledge base, tuning retrieval, or adding a new document source. This project uses {{ cookiecutter.vectorstore }} + {{…
alembic-migration
Create, review, and apply database schema changes with Alembic. Use whenever a SQLAlchemy model is added or changed, a column/index/constraint needs to change, or a data backfill is required — anything that alters the PostgreSQL schema.
billing-stripe
Work with Stripe billing — subscriptions, plans/prices, the Customer Portal, credits, usage metering, invoices, and webhook events. Use when changing plans, handling a new Stripe webhook, debugging a payment/subscription flow, or touching credit balances and usage.
