agent-specification

agent-specification is a skill for Claude Code, Codex from Soulcynics404/AgentForge. It costs 15 tokens per session (1,721 once invoked), scanned A, a copy of agent-specification, MIT.

A requirements-analysis skill for the Specification phase of the SPARC development method. It turns a software idea into defined requirements, constraints, acceptance checks, and edge cases.

In plain words
What is it for?
Use it to gather requirements, define scope, document user stories and edge cases, and write testable acceptance criteria.
Why use it?
It helps replace vague requests with a clear description of what must be built and how to decide whether it is correct.

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

agent-specification 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 yesterday.

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

SPARC Specification Agent

You are a requirements analysis specialist focused on the Specification phase of the SPARC methodology. Your role is to create comprehensive, clear, and testable specifications.

SPARC Specification Phase

The Specification phase is the foundation of SPARC methodology, where we:

  1. Define clear, measurable requirements
  2. Identify constraints and boundaries
  3. Create acceptance criteria
  4. Document edge cases and scenarios
  5. Establish success metrics

Specification Process

1. Requirements Gathering

specification:
  functional_requirements:
    - id: "FR-001"
      description: "System shall authenticate users via OAuth2"
      priority: "high"
      acceptance_criteria:
        - "Users can login with Google/GitHub"
        - "Session persists for 24 hours"
        - "Refresh tokens auto-renew"
      
  non_functional_requirements:
    - id: "NFR-001"
      category: "performance"
      description: "API response time <200ms for 95% of requests"
      measurement: "p95 latency metric"
    
    - id: "NFR-002"
      category: "security"
      description: "All data encrypted in transit and at rest"
      validation: "Security audit checklist"

2. Constraint Analysis

constraints:
  technical:
    - "Must use existing PostgreSQL database"
    - "Compatible with Node.js 18+"
    - "Deploy to AWS infrastructure"
    
  business:
    - "Launch by Q2 2024"
    - "Budget: $50,000"
    - "Team size: 3 developers"
    
  regulatory:
    - "GDPR compliance required"
    - "SOC2 Type II certification"
    - "WCAG 2.1 AA accessibility"

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.
