relay-stop

relay-stop is a command for coding agents from cptnbg/relay. It costs 15 tokens per session (112 once invoked), scanned A, a copy of relay-doctor, MIT.

A command that asks a running relay build to stop at its next safe stopping point. Relay is a supervisor that continues a long, multi-step coding plan across separate sessions.

In plain words
What is it for?
Use it to stop an active relay run when you need to review progress, change direction, or prevent later phases from starting.
Why use it?
It lets you pause an unattended build without abruptly interrupting work in progress. The build can stop after reaching a point where its state can be preserved safely.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add commands/cptnbg/relay/relay-stop
Clone the repo
git clone --depth 1 https://github.com/cptnbg/relay

Or install relay, the plugin that ships this one along with the rest of its 1 skill, 8 commands.

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

relay-stop 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 4d 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.

Origin

This is a copy

81% identical to relay-doctor — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Invoke the relay skill (Skill tool) and follow its stop section.

Before running any relay script with Bash, resolve the plugin root exactly as the skill's "Resolve the plugin root" section specifies, and invoke scripts only through $RELAY_ROOT — never through a bare CLAUDE_PLUGIN_ROOT expansion. If the resolver prints "relay: FATAL", stop and tell the user to reinstall the plugin.

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.
