save-session is a skill for Claude Code, Codex from multiplex-ai/muggle-ai-teams. It costs 31 tokens per session (197 once invoked), scanned A, a copy of checkpoint, MIT.

A session-saving tool that writes the current coding session's state to a dated file.

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

save-session 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 14d 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

75% identical to checkpoint — 12 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

/save-session

This skill is muggle-ai-teams' /save-session command, for Codex. The command itself is ../../../commands/save-session.md, three directories above this file. Read it and follow it as your instructions:

  • Its $ARGUMENTS is what the user wrote after $muggle-ai-teams:save-session, and $1, $2, … are the words of that text; with nothing written, they are empty.
  • It was written for Claude Code. Where it names a Claude Code tool, slash command or path, use the Codex equivalent from ../../host-tool-equivalents.md.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
