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

develop-solution-brief 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 1mo 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.

Solution Brief

A solution brief is a concise, one-page document that communicates the proposed solution to a problem. It serves as the bridge between problem understanding and detailed specification, providing enough context for stakeholders to align on the approach without getting lost in implementation details. The one-page constraint forces clarity and prioritization.

When to Use

  • Pitching a solution approach to stakeholders for buy-in
  • Aligning cross-functional teams on what you're building and why
  • Documenting solution intent before detailed PRD writing
  • Comparing multiple solution options at a high level
  • Communicating product direction to leadership

When NOT to Use

  • Stakeholders are aligned and engineering needs the full specification -> use deliver-prd; the brief pitches, the PRD specifies
  • The problem is not yet framed or agreed -> use define-problem-statement first
  • You are recording a decision already made -> use documentation-and-adrs (technical) or develop-design-rationale (design)
  • You need to compare strategic options across the whole business model -> use lean-canvas

Instructions

When asked to create a solution brief, follow these steps:

  1. Recap the Problem Summarize the problem in 2-3 sentences maximum. Don't re-explain the full problem statement - reference it if needed. The reader should immediately understand what pain point this solution addresses.

  2. Describe the Proposed Solution Explain what you're building in clear, non-technical language. Focus on the user experience and core value proposition. Avoid implementation details - this is about what, not how.

  3. List Key Features Identify 3-5 essential features that comprise the solution. These should be the minimum set needed to solve the problem. Resist the urge to include nice-to-haves - the one-page constraint demands focus.

  4. Define Success Metrics Connect the solution to measurable outcomes. How will you know if this works? Reference metrics from the problem statement and set targets.

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.
