What is requirement-validator?

A checker for pseudo-code specifications, which are informal descriptions of how software should work, across security, completeness, errors, data, performance, and edge cases.

Use it to review team specifications, assign issue severity, apply technology-specific checks, and suggest fixes before development begins.

It finds missing requirements and unclear risks before implementation, when they are easier to fix.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.02266
Opus 5.5	$0.00000	$0.00906
Sonnet 5.5	$0.00000	$0.00453
Haiku 4.5	$0.00000	$0.00227

Security

Grade A, and why

requirement-validator 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 2mo 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.

Requirement Validator Skill

Validates pseudo-code specifications across 6 critical dimensions with customizable checks per tech stack and severity levels.

What This Skill Does

Validates pseudo-code specifications to catch missing details before implementation:

VALIDATION REPORT

✓ PASSED CHECKS
  ✓ Error codes defined
  ✓ Security requirements specified
  ✓ Timeouts included

✗ CRITICAL ISSUES (Must Fix)
  - No rate limiting on public endpoint

⚠ HIGH WARNINGS (Should Fix)
  - Token refresh concurrency not handled

📋 MEDIUM (Nice to Have)
  - Consider adding request tracing

Key features:

6 dimensions: Security, completeness, error handling, data handling, performance, edge cases
Severity levels: CRITICAL (must fix), HIGH (should fix), MEDIUM (nice to have)
Tech-stack aware: Validation rules customized for detected tech stack
Actionable: Each issue includes explanation and suggested fix

When to Use

Before implementing—catch issues early
Reviewing specifications from team members
Quality gate for specification release
Validating pseudo-code across all dimensions

6 Validation Dimensions

1. Security

Checks for authentication, authorization, data protection, and attack prevention.

Questions:

Is authentication specified? (type, providers, tokens)
Is authorization (access control) defined?
Input validation mentioned?
Rate limiting specified?
Sensitive data encryption required?
Secure communication (HTTPS)?
Secure cookie settings?

CRITICAL issues:

No authentication for sensitive operations
SQL/command injection vulnerability
Plaintext secrets or PII
No authorization checks
Missing rate limiting on public endpoints

HIGH issues:

Weak hashing algorithms
Overly broad permissions
Missing input sanitization
No CSRF protection

Customization by tech stack:

Node.js/Next.js:

Check for CORS configuration
Check for helmet/security middleware
JWT secret management

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.

requirement-validator is a skill published in the GitHub repository EladAriel/pseudo-code-prompting-plugin (2 stars, last pushed 9mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,266 tokens. 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.
