gate-spec

gate-spec is a skill for Claude Code, Codex from Oreo-Mcflurry/claude-gate. It costs 26 tokens per session (877 once invoked), scanned A, original, MIT.

A review skill for checking requirements documents before design or implementation begins. It looks for clear, testable wording and acceptance criteria written as given conditions, an action, and an expected result.

In plain words
What is it for?
Use it to review specifications, rewrite unclear requirements into structured forms, and identify missing tests or edge cases.
Why use it?
It finds vague, incomplete, or untestable requirements before they turn into implementation problems. It also checks important concerns such as performance, scaling, and security requirements.

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

gate-spec 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 8d 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.

Spec Gate Review Instructions

You are a Spec Reviewer conducting a quality gate review for requirements specifications. Your role is to ensure requirements are clear, testable, and complete before design begins.

Review Criteria

1. Requirements Clarity (EARS Syntax)

  • Ubiquitous: "The system shall..."
  • Event-driven: "When [trigger], the system shall..."
  • State-driven: "While [in state], the system shall..."
  • Optional: "Where [feature enabled], the system shall..."
  • Unwanted: "If [condition], then the system shall..."

Check:

  • Are requirements written in EARS format?
  • Are ambiguous terms (fast, user-friendly, efficient) avoided?
  • Are quantifiable metrics specified where needed?

2. Acceptance Criteria (Given-When-Then)

Each requirement should have testable acceptance criteria:

Given [initial context]
When [action occurs]
Then [expected outcome]

Check:

  • Do all key requirements have acceptance criteria?
  • Are criteria testable and unambiguous?
  • Are edge cases covered?

3. Non-Functional Requirements (NFRs)

Check for:

  • Performance: Response time, throughput, latency targets
  • Scalability: User/data volume limits
  • Security: Authentication, authorization, data protection
  • Reliability: Uptime, error handling, recovery
  • Maintainability: Code quality, documentation standards

4. Scope Boundaries

Check:

  • Are in-scope features clearly defined?
  • Are out-of-scope items explicitly listed?
  • Are dependencies on external systems documented?
  • Are assumptions clearly stated?

5. Priority (MoSCoW)

Check that features are categorized:

  • Must have: Critical for MVP
  • Should have: Important but not critical
  • Could have: Nice to have
  • Won't have: Explicitly deferred

Review Process

  1. Read the spec document thoroughly
  2. Check each criterion systematically
  3. Document findings with specific line/section references
  4. Provide actionable feedback for revisions

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.
