verify

verify is a command for coding agents from eddiebelaval/squire. It costs 0 tokens per session (290 once invoked), scanned A, original, MIT.

A command that runs a broad software check covering code quality, automated tests, browser-based checks, visual inspection, and the production build.

In plain words
What is it for?
Use it for a full verification, or run only static checks, browser checks, tests, or build checks for a specific feature.
Why use it?
It helps catch different kinds of problems before an application is considered ready.

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 yesterday.

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.

Mode Selection

Parse $ARGUMENTS to determine mode:

  • Empty or "all" → Full verification (all 6 layers)
  • "quick" → Static analysis only (Layer 1)
  • "visual" → Browser verification only (Layer 5)
  • "test" or "tests" → Unit + E2E tests (Layers 2-4)
  • "build" → Build verification only (Layer 6)
  • Anything else → Treat as component/feature name to focus on

Quick Reference

Full Verify

# Layer 1
npm run type-check && npm run lint

# Layer 2
npm test

# Layer 3 (if playwright exists)
npx playwright test

# Layer 4 (using Playwright MCP)
# Navigate, snapshot, screenshot, check console

# Layer 5
npm run build

Visual Verify Sequence

  1. browser_navigate to localhost:3000
  2. browser_snapshot to see page structure
  3. browser_console_messages to check for errors
  4. browser_take_screenshot for visual record
  5. Repeat for key pages

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.
