universal-mcp-sync: Skill for Claude Code

.gemini/skills/agentic-sdd-architecture-review/SKILL.md

agentic-sdd-architecture-review is a skill for Claude Code, Gemini CLI from nawodyaishan/universal-mcp-sync. It costs 31 tokens per session (542 once invoked), scanned A, original, MIT.

A review step for an SDD implementation plan before code is generated. SDD means writing a detailed software design before implementation.

In plain words
What is it for?
Use it as an architecture approval gate between technical planning and creating coding tasks.
Why use it?
It catches unclear scope, missing security or failure handling, unjustified dependencies, and other design problems early.

Skill for Claude CodeGemini CLI

Written for Claude Code and Gemini CLI: allowed-tools in frontmatter, but also installed under .gemini/.

This is nawodyaishan/universal-mcp-sync's own configuration. It tells Claude Code and Gemini CLI how to work on universal-mcp-sync itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything universal-mcp-sync configures →

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

agentic-sdd-architecture-review 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 12d 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.

Agentic SDD Architecture Review

Use this skill as the mandatory gate between technical planning and task generation or code.

Goal

Review the plan as a production architecture gate. Do not implement code.

Required Packet

Review:

  • specs/<feature>/spec.md
  • specs/<feature>/clarify.md, if present
  • specs/<feature>/plan.md
  • specs/<feature>/data-model.md, if present
  • specs/<feature>/contracts/, if present
  • specs/<feature>/test-plan.md, if present
  • .specify/memory/constitution.md
  • relevant ADRs
  • dependency-change notes
  • rollback notes

Checklist

Assess:

  • scope is clear
  • open questions are resolved or explicitly deferred
  • plan follows existing architecture
  • new abstractions are justified
  • existing libraries/framework features are used before custom layers
  • dependencies are justified and approved
  • data ownership is clear
  • migrations and rollback are documented
  • sensitive data and retention rules are considered
  • API compatibility and error responses are defined
  • auth and authorization boundaries are explicit
  • input validation and injection risks are considered
  • observability and failure modes are defined
  • deployment and rollback impact are understood
  • tests cover the core risks

Decision

Return one of:

  • Approved: task breakdown may begin.
  • Needs changes: list blocking changes before approval.
  • Rejected: the plan is structurally unsafe or inconsistent with goals.

Writing Review Artifacts

Create or update specs/<feature>/review.md with:

  • reviewed artifacts
  • findings by severity
  • approval status
  • required changes
  • optional improvements
  • reviewer and date placeholders

If the plan is approved, update the approval status in plan.md only if the user explicitly asked you to maintain artifacts.

Stop Conditions

Do not approve when:

  • a high-risk area lacks explicit human approval
  • rollback is missing for migrations or operational risk
  • dependencies are unjustified
  • tests are absent for behavior, security, or data boundaries
  • plan contradicts constitution or ADRs
  • code generation would require guessing

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.

agentic-sdd-architecture-review is a skill published in the GitHub repository nawodyaishan/universal-mcp-sync (6 stars, last pushed 1mo ago), licensed MIT. It adds 31 tokens to every session and 542 once invoked, about $0.0002 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 2026-08-31.
