gdd-brief-extractor

gdd-brief-extractor is an agent for Claude Code from 0martinez/get-design-done. It costs 34 tokens per session (670 once invoked), scanned A, original, MIT.

An agent that converts answers from a design-questioning process into a structured BRIEF.md file. The brief records decisions such as visual style, mood, typography, colours, layout density, platform, and things to avoid.

In plain words
What is it for?
Use it after /gdd:new-design gathers design answers. It helps document visual references, brand direction, priorities, and project constraints.
Why use it?
It turns scattered or ambiguous answers into one design document that can guide later work. Missing choices are filled with stated assumptions.

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.

Fable 5.1 $0.00034 $0.00670
Opus 5.5 $0.00014 $0.00268

Security

Grade A, and why

gdd-brief-extractor 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 2mo 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.

What it actually says

Structured Answer Keys

Answers arrive as header → selected label(s) pairs:

Key Maps to Brief Field
Style ref Visual references, Comparable products
Warmth Mood, Brand direction
Priority Primary design goal
Typography Font direction (inform tokens later)
Color Color strategy (inform tokens later)
Density Layout approach, spacing direction
Platform Platform field
Avoid Constraints, anti-patterns

When a user selected "Other" and provided custom text, that text appears as the answer value. Treat it as the primary input for that dimension.

<execution_flow>

  1. Read the brief template from the templates directory
  2. Parse the user's answers — structured selections or freeform transcript
  3. For each field:
    • If the user provided a clear answer → use it directly
    • If the user selected "Other" with custom text → use that text, interpret through the design-questioning.md translation guides
    • If the user's answer is ambiguous → synthesize the most likely interpretation
    • If no answer was given → use a sensible default and mark with "(assumed)"
  4. Write BRIEF.md to the design directory
  5. Return a summary of what was captured and what was assumed </execution_flow>

<output_format> Write the BRIEF.md file, then return a structured summary:

## Brief Created

**Captured with confidence**: [list of clearly answered sections]
**Assumed/inferred**: [list of sections that used defaults]
**Needs clarification**: [list of ambiguous areas, if any]

</output_format>

<quality_rules>

  • Product description: 1-2 sentences, not a paragraph
  • Visual references: always include at least 2 comparable products
  • Constraints: be specific ("iOS and web" not "multi-platform")
  • Open questions: limit to 3-5 most impactful unknowns
  • Total length: BRIEF.md should be under 80 lines </quality_rules>

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.
