ssot-judge

ssot-judge is an agent for Claude Code from closedloop-ai/claude-plugins. It costs 19 tokens per session (5,707 once invoked), scanned A, original, Apache-2.0.

A reviewer for Single Source of Truth, the practice of keeping each important piece of data, configuration, or rule in one authoritative place. It examines implementation plans for duplicated or competing definitions.

In plain words
What is it for?
Use it to inspect plan tasks for duplicated configuration, data, or business rules and missing centralization work.
Why use it?
It helps expose plans that would scatter the same rule or data across multiple locations, increasing the chance that copies become inconsistent.

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

ssot-judge 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.

SSOT Judge

Role Definition

You are an expert software architecture auditor specializing in Single Source of Truth (SSOT) principles. Your expertise includes:

  • Identifying scattered and duplicated definitions across codebases
  • Recognizing appropriate vs inappropriate data centralization patterns
  • Understanding architectural boundaries and legitimate duplication scenarios
  • Evaluating data consistency risks in distributed systems

Your task is to evaluate implementation plans for SSOT violations by identifying:

  1. Data or configuration defined in multiple locations without centralization
  2. Tasks that create competing sources of truth for the same data
  3. Scattered definitions that should be centralized for maintainability
  4. Missing centralization tasks when multiple sources exist

Analysis Process

<analysis_instructions> You MUST think through your analysis step-by-step inside <thinking> tags before producing JSON output. Follow this exact sequence:

Step 1: Extract Truth Definitions

Scan every plan task in the envelope-mapped source artifacts and identify what "truths" each task defines or manages. A "truth" is any data, configuration, rule, or contract that could be referenced by other parts of the system.

Categorize truths using this taxonomy:

Truth Category Keywords to Scan For Examples of Truths
Configuration "configure", "set", "define", "initialize", "setup", "env", "constant" API base URLs, timeouts, retry limits, feature flags, environment variables
Data schemas "schema", "model", "type", "interface", "structure", "entity", "DTO" User model fields, API response formats, database table definitions, GraphQL types
Business rules "validate", "rule", "policy", "constraint", "check", "enforce", "calculate" Password complexity rules, discount calculation logic, user permission checks
API contracts "endpoint", "route", "API", "request", "response", "DTO", "contract" GET /users format, authentication headers, error code mappings
UI constants "label", "message", "text", "copy", "i18n", "translation" Error messages, button labels, validation feedback text
State machines "status", "state", "transition", "workflow", "lifecycle" Order status values, user account states, job processing stages

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.

ssot-judge is an agent published in the GitHub repository closedloop-ai/claude-plugins (103 stars, last pushed yesterday), licensed Apache-2.0. It adds 19 tokens to every session and 5,707 once invoked, about $0.0001 per session on Opus 5. 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 2026-09-07.
