What it does
Session Persist is an agent skill from ruvnet/ruflo. Persist and restore agent sessions across conversations with state snapshots
Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
Example prompts
- “/session-persist”
Requirements
- Pre-approved tools (allowed-tools): mcp__plugin_ruflo-core_ruflo__session_save, mcp__plugin_ruflo-core_ruflo__session_restore, mcp__plugin_ruflo-core_ruflo__session_list, mcp__plugin_ruflo-core_ruflo__session_info, mcp__plugin_ruflo-core_ruflo__session_delete, mcp__plugin_ruflo-core_ruflo__hooks_session-start, mcp__plugin_ruflo-core_ruflo__hooks_session-end, mcp__plugin_ruflo-core_ruflo__hooks_session-restore, Bash
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Save session — call mcpplugin_ruflo-core_ruflosession_save to snapshot current state
- List sessions — call mcpplugin_ruflo-core_ruflosession_list to see all saved sessions
- Restore — call mcpplugin_ruflo-core_ruflosession_restore to resume a previous session
- Info — call mcpplugin_ruflo-core_ruflosession_info for session details and metadata
- Clean up — call mcpplugin_ruflo-core_ruflosession_delete to remove old sessions
What it can do on your machine
Read from SKILL.md and the folder at commit 6051f67. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
mcp__plugin_ruflo-core_ruflo__session_savemcp__plugin_ruflo-core_ruflo__session_restoremcp__plugin_ruflo-core_ruflo__session_listmcp__plugin_ruflo-core_ruflo__session_infomcp__plugin_ruflo-core_ruflo__session_deletemcp__plugin_ruflo-core_ruflo__hooks_session-startmcp__plugin_ruflo-core_ruflo__hooks_session-endmcp__plugin_ruflo-core_ruflo__hooks_session-restoreBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Session Persist loads about 415 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 123 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Can I use Session Persist in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill session-persist -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/session-persist, .gemini/skills/session-persist, .github/skills/session-persist and .opencode/skills/session-persist in your project.
What does Session Persist need to run?
SKILL.md names no scripts, command-line tools or credentials: Session Persist is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__plugin_ruflo-core_ruflo__session_save, mcp__plugin_ruflo-core_ruflo__session_restore, mcp__plugin_ruflo-core_ruflo__session_list, mcp__plugin_ruflo-core_ruflo__session_info, mcp__plugin_ruflo-core_ruflo__session_delete, mcp__plugin_ruflo-core_ruflo__hooks_session-start, mcp__plugin_ruflo-core_ruflo__hooks_session-end, mcp__plugin_ruflo-core_ruflo__hooks_session-restore, Bash.
Does Session Persist access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
