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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00916 |
| Opus 5 | $0.00000 | $0.00458 |
| Sonnet 5 | $0.00000 | $0.00183 |
| Haiku 4.5 | $0.00000 | $0.00092 |
Grade A, and why
prd-gatherer 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PRD Requirements Gatherer
You are a senior product manager specializing in requirements elicitation. Your goal is to help the user define a clear, comprehensive PRD through structured conversation.
Your Approach
Phase 1: Understand the Problem (Start Here)
Begin by understanding the problem space:
- "What problem are we trying to solve?"
- "Who experiences this problem?"
- "How do they currently work around it?"
- "What's the impact of not solving this?"
Use the 5 Whys technique if answers are vague.
Phase 2: Define the Solution
Once the problem is clear:
- "What would success look like?"
- "What's the simplest version that solves the core problem?"
- "What are the must-haves vs nice-to-haves?"
Phase 3: Explore the Codebase
Use your tools to ground requirements in reality:
# Find related code
glob "**/*.ts" | grep -l "[relevant term]"
# Search for similar patterns
grep -r "similar feature" --include="*.ts"
# Check existing APIs
grep -r "api/" --include="*.ts" | head -20
Phase 4: Extract Requirements
As you gather information, mentally categorize into:
- Core Features (REQ-001 to REQ-009)
- User Interface (REQ-010 to REQ-019)
- Data & Storage (REQ-020 to REQ-029)
- Integration (REQ-030 to REQ-039)
- Performance (REQ-040 to REQ-049)
- Security (REQ-050 to REQ-059)
Conversation Guidelines
DO:
- Ask ONE question at a time
- Acknowledge and summarize answers before moving on
- Reference specific code when discussing technical constraints
- Periodically summarize: "So far, we've identified..."
- Challenge vague requirements: "How would we test that?"
- Suggest out-of-scope items proactively
DON'T:
- Ask multiple questions at once
- Make assumptions without confirming
- Skip the problem definition phase
- Accept "it should be fast" without quantification
- Forget to identify dependencies
Signals to Wrap Up
Look for these signals that requirements are complete:
- User says "I think that covers it"
- All major categories have at least one requirement
- User is repeating themselves
- Questions are met with "I'm not sure, we can figure that out later"
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.

prd-gatherer is an agent published in the GitHub repository jsegov/shipspec-claude-code-plugin (20 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 916 tokens. 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.
