What it does

Health is an agent skill from ThinkfleetAI/memmesh. Diagnose MemMesh connectivity and correctness — is the MCP server reachable, is the key/config valid, do read and write actually work? Use when memory operations fail, searches return empty unexpectedly, observe/save errors occur, or to confirm the plugin is wired correctly.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Persistent, self-improving memory for AI agents. Local-first Rust memory engine with MCP support. The licence is Apache-2.0.

When your agent uses it

  • Memory operations fail
  • Searches return empty unexpectedly
  • Observe/save errors occur
  • Confirm the plugin is wired correctly

Example prompts

  • “/health”

Requirements

  • Node.js
  • A credential in MEMMESH_API_KEY

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Wiring
  2. Read/write round-trip
  3. Common failures
  4. Report

What it can do on your machine

Read from SKILL.md and the folder at commit bba48f8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • MEMMESH_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Health loads about 404 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~404

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 passed

The automated check found no risky patterns in SKILL.md.

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.

Diagnose the MemMesh plugin when something seems off.

1. Wiring

bash
memmesh doctor        # binary on PATH, MCP config written, skill present, hooks

If the MCP server isn't listed by the agent, the config didn't take — re-run npx @thinkfleet/memmesh install --force and restart the tool.

2. Read/write round-trip

Prove the engine actually works, end to end:

  1. memory_save a throwaway item (type: "fact", scope: "session", content "memmesh healthcheck <runid>").
  2. memory_search for "healthcheck <runid>" — assert it comes back.
  3. memory_delete (hard) the throwaway so nothing lingers.

If step 1 fails with a cap error, you're at the free-tier 500-item limit — see stats and suggest forget/dream.

3. Common failures

4. Report

State clearly what works and what doesn't — don't claim healthy if the round-trip didn't complete.

Diagnose MemMesh connectivity and correctness — is the MCP server reachable, is the key/config valid, do read and write actually work?

When should I use Health?

Health fits situations like: memory operations fail; searches return empty unexpectedly; observe/save errors occur; confirm the plugin is wired correctly.

How do I install Health in Claude Code?

Run `npx skills add ThinkfleetAI/memmesh --skill health -a claude-code`. Or copy the skill folder (integrations/memmesh-plugin/skills/health in ThinkfleetAI/memmesh) into .claude/skills/health in your project. Claude Code loads it when a task matches its description.

How do I install Health in Codex?

Run `npx skills add ThinkfleetAI/memmesh --skill health -a codex`. Or copy the skill folder (integrations/memmesh-plugin/skills/health in ThinkfleetAI/memmesh) into .agents/skills/health in your project. Codex loads it when a task matches its description.

Can I use Health 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 ThinkfleetAI/memmesh --skill health -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/health, .gemini/skills/health, .github/skills/health and .opencode/skills/health in your project.

What does Health need to run?

Going by SKILL.md and its folder, Health needs the command-line tools its instructions call (npx) and credentials named MEMMESH_API_KEY. Our summary lists: Node.js; A credential in MEMMESH_API_KEY.

Does Health access the network?

SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Health safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Health use?

Health is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Health use?

About 404 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
