verify-gate

verify-gate is a skill for Claude Code from uqeu/estelle-cli. It costs 37 tokens per session (222 once invoked), scanned A, original, Apache-2.0.

A pre-release checklist that checks a code change before it is merged or shipped. It examines the build, formatting, types, test coverage, security findings, and the proposed change.

In plain words
What is it for?
Use it to verify pull requests and release candidates before opening or merging them. It is also for checking that code uses real, documented interfaces rather than invented ones.
Why use it?
It reduces the chance of merging code that does not build, lacks tests, contains security problems, or does not match the specification. It gives a pass or fail result and identifies the failed check.

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-gate 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 today.

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

verify-gate

Estelle's "is this actually done?" gate. Nothing merges unverified.

Checklist (all must pass)

  1. Build green (compiles / imports).
  2. Lint + format clean (ruff / prettier).
  3. Static/type checks pass.
  4. Coverage ≥ target (Estelle: 100% on new pure cores) — the test summary line is the source of truth.
  5. Grounding gate: no invented APIs.
  6. Security (threat-scan): no CRITICAL/HIGH CVE, secret, or SAST finding.
  7. Diff review (diff-review): Standards + Spec axes, no blockers.

Output

A pass/fail verdict with the one line that failed. Serves every PR; the swarm runs this before opening a PR.

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.
