auto-verify

auto-verify is a skill for Claude Code from vertti/se-cove-claude-plugin. It costs 0 tokens per session (637 once invoked), scanned A, original, MIT.

A small workflow helper that recommends a verification command for complex software tasks with testable behavior and a high risk of subtle bugs.

In plain words
What is it for?
Use it for tasks such as asynchronous code, caching, authentication, access control, input validation, or other security-sensitive behavior.
Why use it?
It reminds users to check important code when a mistake could be hard to notice, while avoiding unnecessary checks for simple work.

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

auto-verify 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 9d 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.

Auto-Verify Skill (Software Engineering)

This skill suggests using /verify for software engineering tasks that would benefit from systematic verification.

Design Philosophy

Be minimal and non-eager. Users invoke /verify when they want it. This skill only suggests verification in specific high-value scenarios where the user might not realize verification would help.

When to Suggest Verification

Only suggest /verify when the user's question involves ALL of these:

  1. Significant complexity - Not a trivial fix or simple question
  2. High risk of subtle bugs - Async patterns, state management, security
  3. Verifiable claims - There are specific behaviors that can be tested

Good Candidates

Complex code patterns with known pitfalls:

  • React hooks with async behavior (useEffect, useCallback + async)
  • Debouncing/throttling implementations
  • Race condition scenarios
  • Caching strategies
  • Authentication/authorization flows

Security-sensitive operations:

  • Input validation and sanitization
  • Token handling and session management
  • Password hashing and credential storage
  • Encryption/decryption implementations
  • Access control and permission checks

Complex async patterns:

  • Promise chains with error handling
  • Concurrent operations with shared state
  • Retry logic with backoff strategies
  • Streaming and chunked data processing
  • WebSocket or real-time connection handling

Financial and critical operations:

  • Payment processing logic
  • Inventory or balance calculations
  • Audit logging implementations
  • Data migration scripts
  • Rate limiting implementations

Architectural decisions with significant tradeoffs:

  • State management approach (Redux vs alternatives)
  • Microservices vs monolith
  • Database schema design
  • API design patterns

Bug investigations where the cause is uncertain:

  • "I think the bug is X but not sure"
  • Intermittent failures
  • Production issues with incomplete information

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.

auto-verify is a skill published in the GitHub repository vertti/se-cove-claude-plugin (20 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 637 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 2026-08-30.
