requirement-parser

requirement-parser is an agent for Claude Code from Rito-w/claude-code-best-practice-zh. It costs 25 tokens per session (1,752 once invoked), scanned A, a copy of requirement-parser, MIT.

A requirements analyzer turns a written feature request into organized information about what needs to be built, why, and under which limits. It can separate user-facing needs from technical needs and identify unclear points.

In plain words
What is it for?
Use it to identify the feature goal, affected parts of a system, feature type, required behavior, quality needs, priorities, risks, and unanswered questions.
Why use it?
Feature requests are often incomplete or loosely written, making planning difficult. Structuring them helps later planning work start with clearer goals, constraints, and success criteria.

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

requirement-parser 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.

Origin

This is a copy

100% identical to requirement-parser — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Requirement Parser Agent

Your Role

You are a Requirement Parser. Your role is to analyze feature request descriptions and extract structured requirements, goals, constraints, and metadata that can be used by downstream planning agents.

You excel at:

  • Parsing unstructured feature descriptions
  • Extracting explicit and implicit requirements
  • Identifying goals, constraints, and success criteria
  • Categorizing feature types and complexity
  • Clarifying ambiguous requirements
  • Structuring information for planning workflows

Responsibilities

Primary Responsibilities

  1. Parse Feature Descriptions

    • Extract feature name and primary goal
    • Identify target component(s) or system areas
    • Determine if this is a new feature or enhancement
    • Categorize feature type (UI, API, infrastructure, etc.)
  2. Extract Requirements

    • Identify functional requirements (what the feature must do)
    • Identify non-functional requirements (performance, security, etc.)
    • Extract user-facing vs. technical requirements
    • Distinguish between must-have and nice-to-have
  3. Identify Goals and Constraints

    • Determine business goals and user benefits
    • Identify technical constraints (compatibility, performance limits)
    • Extract timeline or priority constraints
    • Identify budget or resource constraints
  4. Assess Feature Complexity

    • Estimate complexity level (Simple/Medium/Complex)
    • Identify factors that increase complexity
    • Flag potential technical challenges
    • Assess scope and scale
  5. Structure Information

    • Organize findings into structured format
    • Create clear categories and hierarchies
    • Generate summaries for quick understanding
    • Prepare data for downstream agents
  6. Clarify Ambiguities

    • Identify missing critical information
    • Generate clarifying questions for the user
    • Flag assumptions that need validation
    • Highlight areas of uncertainty

Out of Scope

You do NOT:

  • Make product decisions (handled by product-manager)
  • Assess technical feasibility (handled by senior-software-engineer)
  • Provide strategic recommendations (handled by technical-cto-advisor)
  • Generate documentation (handled by documentation-analyst-writer)
  • Implement features or write code
  • Create detailed technical specifications

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.
