verify

verify is a command for coding agents from vertti/se-cove-claude-plugin. It costs 13 tokens per session (2,218 once invoked), scanned A, original, MIT.

A command that checks a code answer, design, or bug fix against its requirements. It supports faster or deeper checks and can focus the review on areas such as security, testing, performance, APIs, or error handling.

In plain words
What is it for?
Use it to review implementation choices, investigate bugs, validate API guidance, and assess proposed fixes at different levels of depth.
Why use it?
It helps expose incorrect assumptions and missed edge cases before a change is trusted. Independent verification is especially useful for complex code or architecture decisions.

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

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 5d 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.

/verify Command (Software Engineering)

FIRST: Check for Empty Input

If the user runs /verify with no question (empty arguments or only whitespace), OUTPUT the following help text directly to the user (copy it verbatim as your response), then STOP:

## /verify - Chain of Verification

Verify code, architecture, or bug fixes by checking against requirements, not implementation.

**Usage:**
/verify <question>
/verify --quick <question>           # Fast check (haiku, 1 executor)
/verify --thorough <question>        # Deep check (opus, 4+ executors)
/verify --focus=security <question>  # Prioritize security tasks

**Options:**
| Flag | Short | Description |
|------|-------|-------------|
| --quick | -q | Fast verification, minimal depth |
| --thorough | -t | Comprehensive verification |
| --focus=X | -f X | Focus area: security, performance, api, testing, error-handling, style, scalability |

**Examples:**
- /verify How do I debounce in React?
- /verify --quick Is this null check right?
- /verify -t -f security Review the auth flow

**When to use:** Complex code, architecture decisions, bug investigations, API questions
**Skip for:** Typos, simple renames, obvious answers

Do NOT proceed with verification if no question was provided. Just output the help above.


Verify code, architecture decisions, and bug fixes using the Software Engineering Chain of Verification (SE-CoVe) pattern.

Usage

/verify <software engineering question or problem>
/verify --quick "Is this null check correct?"
/verify --thorough "Review this authentication flow"
/verify --focus=security "Analyze the login endpoint"

Command-Line Options

Flag Short Description
--quick -q Fast verification with minimal depth
--thorough -t Comprehensive verification with maximum depth
--focus=X -f X Prioritize a specific verification area
(no flags) Standard verification (default)

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.

verify is a command published in the GitHub repository vertti/se-cove-claude-plugin (20 stars, last pushed 7mo ago), licensed MIT. It adds 13 tokens to every session and 2,218 once invoked, about $0.0001 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 2026-08-30.
