stop

stop is a skill for Claude Code from zkysar1/Claude-Mind. It costs 122 tokens per session (5,164 once invoked), scanned A, original, MIT.

A command for safely stopping an autonomous learning process run by an agent. It waits for ongoing checks to finish, saves the session state, and returns the agent to an inactive mode.

In plain words
What is it for?
Stopping a named learning agent from any terminal, either leaving it ready for state changes or placing it in read-only mode.
Why use it?
It prevents a stop from interrupting unfinished work or affecting the wrong agent. Requiring the agent's name makes the target explicit.

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

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 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.

How it starts

The opening of the file, as written. The whole thing — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/stop -- Stop the Autonomous Learning Loop

USER-ONLY COMMAND. Claude must NEVER invoke this skill.

Syntax

/stop <agent-name>          # Stop the named agent + drop to assistant (reconciliation-ready)
/stop <agent-name> --reader # Stop the named agent + drop to reader (read-only, walking away)

Agent name is REQUIRED. A bare /stop (no positional argument) is refused with a clear error and the list of available agent directories. This prevents the cross-session "wrong-agent stop" failure mode where a session's .active-agent-<SID> binding has been silently overwritten or cleared (e.g., NO_AGENT window, or another /start rebinding the SID), leaving /stop no safe default. Requiring the explicit name also enables stops from any terminal — a side benefit, not a workaround. (Incident: 2026-04-24 — bare /stop typed in a NO_AGENT window stopped the wrong agent because the binding fell back to a different active agent's session.)

After stop, the agent lands in assistant mode by default so the user can immediately reconcile state (mark a missed goal, edit a tree node, add a guardrail) without a mode switch. Pass --reader for the read-only safe floor when walking away.

Step 0: Load Conventions -- Bash: load-conventions.sh with each name from the conventions: front matter. Read only the paths returned (files not yet in context). If output is empty, all conventions already loaded -- proceed to next step.

Step 0.5: Parse arguments — flag-parsing runs before positional-parsing so /stop --reader (no agent-name) is not mis-interpreted as /stop <agent-name=--reader>.

  1. Flag parsing: If any argument is the literal string --reader, set target_mode = "reader". Otherwise target_mode = "assistant". This determines where the agent lands after the stop completes. Unknown flags are ignored (user will see the default output and can re-try).

  2. Agent name resolution (REQUIRED): Take the first argument that does NOT start with -- as <agent-name>. The positional argument is mandatory — there is NO fallback to current session binding.

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.

stop is a skill published in the GitHub repository zkysar1/Claude-Mind (5 stars, last pushed today), licensed MIT. It adds 122 tokens to every session and 5,164 once invoked, about $0.0006 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.
