brainstorming-contractual

brainstorming-contractual is a skill for Claude Code, Codex from SymbolicLight-AGI/contractual-skill. It costs 35 tokens per session (1,044 once invoked), scanned A, original, MIT.

A discussion method for turning an unclear idea, feature, architecture question, or behavior change into an agreed design. It records assumptions, decisions, risks, and what needs to happen before implementation.

In plain words
What is it for?
Use it for feature planning, architecture exploration, behavior changes, edge-case decisions, and test planning before implementation.
Why use it?
It helps teams clarify the problem and resolve important questions before code or irreversible changes are made. It keeps uncertain details visible instead of silently guessing.

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

brainstorming-contractual 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 9d 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.

Brainstorming Ideas Into Designs Contract

When To Use

Use this Skill before implementation when the user has a raw idea, design question, architectural direction, behavior change, or feature concept that needs clarification.

Do not use this Skill as an implementation mode. If the user asks to code, modify behavior, create files, deploy, or make irreversible changes while this Skill is active, stop and ask for an explicit transition to an implementation workflow.

Goal

Turn vague ideas into clear, validated designs and specifications. The useful outcome is shared understanding, explicit assumptions, documented decisions, risks, and an implementation handoff only after the design is accepted.

Audience

  • Product or business owners clarifying desired behavior.
  • Engineers exploring architecture, components, data flow, edge cases, or test strategy.
  • Reviewers who need a decision log and assumptions before implementation.

Inputs

  • Required: the idea, feature, behavior, architecture question, or problem to explore.
  • Optional: current files, documentation, plans, prior decisions, constraints, success criteria, non-goals, and project standards.
  • Privacy: do not repeat credentials, secrets, customer data, or private production details unless they are necessary and safely redacted.

If key context is missing, continue only by marking assumptions and asking one focused question at a time.

Context

Review available project state before designing when project context is provided. Distinguish what already exists from what is proposed. Treat unconfirmed constraints as assumptions.

Do not speculate about repository files, architecture, or prior decisions without evidence from user-provided material or read-only inspection.

Workflow

  1. Understand current context before proposing solutions.
  2. Ask one question per message, preferring multiple-choice questions when useful.
  3. Clarify purpose, target users, constraints, success criteria, and explicit non-goals.
  4. Clarify or propose assumptions for performance, scale, security, privacy, reliability, maintenance, and ownership.
  5. Create an understanding summary with assumptions and open questions.
  6. Do not proceed to design until the user confirms the understanding.
  7. Explore 2-3 viable approaches and lead with a recommended option.
  8. Compare tradeoffs in complexity, extensibility, risk, and maintenance.
  9. Present the design incrementally and validate each section.
  10. Maintain a decision log with decisions, alternatives, and rationale.
  11. After validation, prepare documentation or an implementation handoff if explicitly requested.

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.

brainstorming-contractual is a skill published in the GitHub repository SymbolicLight-AGI/contractual-skill (21 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 1,044 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 2026-08-30.
