What it does

Heartbeat is an agent skill from modimihir07/agentic-os. Lightweight system health monitoring skill

Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `eval.json`, `learnings.md` and `score-history.json`).

The repository describes itself as: Agentic OS: Multi-agent orchestration platform for opencode, Hermes & Gemini CLI. Skills hub, scheduler, cost analytics, memory & backup. The licence is MIT.

Example prompts

  • “/heartbeat”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Check all 3 agents (opencode, hermes, agy) are online
  2. Check disk usage (< 90%)
  3. Check memory pressure (< 80%)
  4. Scan recent audit log for errors
  5. Update brain/recent-decisions.md if issues found
  6. Return health summary

What it can do on your machine

Read from SKILL.md and the folder at commit c7ebbb4. 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

    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

Heartbeat loads about 217 tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~13
When it runs · the whole SKILL.md, loaded when a task matches
~217

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.
