verify

A full quality-check command for a LayerCake project. It runs checks for synchronized agent files, security dependencies, types, code style, formatting, tests, and the production build.

In plain words
What is it for?
Running the standard QA checks, optionally including AE host tests, and reporting which checks passed, failed, or were skipped.
Why use it?
It brings the project's main verification steps into one repeatable check and helps identify problems introduced by code changes.

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 2d 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.

What it actually says

Run the LayerCake full verification suite and fix failures you introduce.

Full QA always includes AgentSync. If you edited .ai/src/, run agentsync sync before agentsync check.

In Cursor, run the QA Shell with required_permissions: ["all"]. agentsync check fails in the sandbox every time (Failed to prepare temporary workspace for check / .cursor/: Operation not permitted) — that is not drift; skip the sandboxed attempt.

  1. Run:
agentsync check
npm audit --audit-level=high
npm run typecheck
npm run lint
npm run fmt:check
npm test
npm run build
  1. If $ARGUMENTS contains ae (or the user asked for host tests), also run:
npm run test:ae

Host tests skip when AE env is unset — report skips clearly rather than treating them as failures.

  1. Summarize: commands run, pass/fail/skip, and any fixes applied. Keep changes scoped to making verification green.
Changes

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 alphacornutum/layercake (0 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 266 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 2026-08-31.
