design-compliance

design-compliance is a skill for Claude Code, Codex from paruff/uFawkesAI. It costs 27 tokens per session (437 once invoked), scanned A, original, MIT.

A checker that compares implemented code and infrastructure with a written software design. It examines how components, interfaces, data models, and integrations fit together.

In plain words
What is it for?
It checks layer dependencies, component boundaries, API contracts, data shapes, error types, database access, messaging, authentication, and external-service integrations.
Why use it?
It finds differences between the planned architecture and the system that was actually built.

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

design-compliance 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 7d 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

Skill: Design Compliance Validation

Load trigger: "load design-compliance skill" > DORA: Cap 1 (AI Policy) Token cost: Low

Purpose

Verify that the build output matches the design.

Responsibilities

  • Validate architecture alignment
  • Validate component boundaries
  • Validate interfaces and data models
  • Validate integration points

Inputs

  • design.md
  • Build output (code, manifests)

Outputs

  • design-compliance.json

Validation Rules

Architecture Alignment

  • Layer structure follows design (UI → Service → Data)
  • No circular dependencies between layers
  • Dependency direction matches design
  • Shared libraries used as intended

Component Boundaries

  • Components match design decomposition
  • No cross-component coupling beyond what design specifies
  • API contracts between components match design

Interfaces and Data Models

  • Public interfaces match design
  • Data models match design schemas
  • Request/response shapes match design
  • Error types match design

Integration Points

  • External service integrations match design
  • Database access patterns match design
  • Messaging patterns match design
  • Authentication flow matches design

Output Format

      "status": "pass | fail",
      "details": "Description of compliance or violation"
    }
  ],
  "violations": []
}

Success Criteria

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.
