agentic-process-monitor

agentic-process-monitor is a skill for Claude Code from terrylica/cc-skills. It costs 28 tokens per session (1,866 once invoked), scanned A, original, MIT.

Patterns for watching background processes using status files, heartbeat timestamps, and a monitoring agent. A heartbeat is a regular signal showing that a process is still responding.

In plain words
What is it for?
Use it to monitor background commands, detect stale processes, stop hung work, enforce time limits, and return the result to the main coding session.
Why use it?
It helps distinguish successful, failed, timed-out, and stuck work instead of waiting indefinitely or guessing from incomplete output.

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

agentic-process-monitor scanned grade A with 1 finding 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 13d 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.

Agentic Process Monitor

Patterns for monitoring background processes from Claude Code — detecting success, failure, timeout, and hung processes, then returning results to the main context to drive the next action.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Architecture: Sentinel + Heartbeat + Agent

Main Context                          Monitor Agent (subagent)
─────────────                         ──────────────────────
1. Start work (Bash run_in_background)
   └─ work wrapper writes sentinel files
2. Launch Agent (poll every 15s) ────► poll loop:
3. Continue other work                  .status exists? → return result
                                        .heartbeat stale? → kill, return error
                                        elapsed > max? → kill, return timeout
4. Agent returns ◄──────────────────── detected outcome
5. Act on result (next step / retry / abort)

Why this architecture: The main context stays lean (no polling tokens burned). The subagent handles all the waiting. If the subagent itself fails, the main context can recover by checking sentinel files directly.


Sentinel Protocol

The work process writes 4 files to a known directory (e.g., /tmp/<project>-monitor/):

File When Written Purpose
<step>.pid On start PID for timeout kill
<step>.heartbeat Every N seconds during work mtime freshness = alive proof
<step>.status On exit (SUCCESS / FAILED) Completion sentinel
<step>.result On success Structured output (JSON)

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.

agentic-process-monitor is a skill published in the GitHub repository terrylica/cc-skills (73 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 1,866 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
