verify

verify is a skill for Claude Code from spacegrowth/claude-relay. It costs 83 tokens per session (1,688 once invoked), scanned A, original, MIT.

A report checker that compares an executor's claims with its staged files and declared counts. It can also rerun the commands listed in the report when requested.

In plain words
What is it for?
Use it to check a current or older executor report and optionally rerun its stated tests or checks.
Why use it?
It catches malformed reports and mismatches between reported work and staged reality, while making clear that matching counts do not prove the work was correct.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Call relay as ${CLAUDE_PLUGIN_ROOT}/bin/relay (Claude Code substitutes the plugin's absolute path when this skill loads) — not bare relay, which often isn't on the Bash tool's non-interactive PATH.

Run: ${CLAUDE_PLUGIN_ROOT}/bin/relay verify $session_id

Add --packet N for an older packet, and --rerun to also re-run the pytest-shaped commands the report declares (off by default so verify stays fast).

READ THIS BEFORE YOU READ A VERDICT

A COUNTS-MATCH must never be read as "the report is true." This is the whole design constraint, not a footnote. The field data behind it: across ~15 real executor reports, a counts-verifier would have caught exactly one thing (a lint miss). Every dangerous problem was premise-level — wrong oracle, wrong write-side, suite green in the wrong venv — and every one of those is invisible to re-running the declared commands.

So: this tool checks that the numbers line up. It cannot check that the work was right. Your judgement on the staged diff stays the real check — if you let a COUNTS-MATCH displace it, you have made relay less safe, not more, because you have swapped the thing that caught the real problems for the thing that catches lint misses.

That is also why there is no "PASS", no "VERIFIED", and no "clean" in this command's vocabulary. The verdict words are deliberately chosen so they cannot be over-read at a glance.

The verdicts

Verdict Exit Means
COUNTS-MATCH 0 The checkable numbers agree. That is all it means. Still read the diff.
MISMATCH 1 A claim contradicts staged reality — a file claimed but never staged, a "staged" confirmation over an empty index, or (with --rerun) a declared test count that doesn't reproduce.
MALFORMED 2 The report violates the REPORT FORMAT's TL;DR contract — most often a missing UNVERIFIED: line. Per #6, an absent UNVERIFIED line reads as malformed, never as "nothing to report."
INCONCLUSIVE 3 A check you asked for did not complete (e.g. --rerun produced no N passed count). Not a COUNTS-MATCH with a caveat — nothing was compared.

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 skill published in the GitHub repository spacegrowth/claude-relay (1 stars, last pushed today), licensed MIT. It adds 83 tokens to every session and 1,688 once invoked, about $0.0004 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.
