monitor

A bounded process for checking an explicitly defined condition over time using an available source of evidence.

In plain words
What is it for?
Use it to watch for a specified change, deadline, result, or external state during a defined period, with a stated checking schedule and handoff or notification method.
Why use it?
It prevents a one-time check from being mistaken for ongoing observation and makes the time limit, change threshold, and stopping point clear.

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

monitor 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 2d 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.

What it actually says

Monitor

Useful when

The user wants a change, deadline, result, or external state checked again over a defined period and the host supports a suitable observation mechanism.

Skip when

One immediate check is sufficient, no observation source exists, or the request has no bounded duration or stopping condition.

Suggested inputs

  • observable condition and evidence source;
  • cadence, deadline, or stopping condition;
  • material-change threshold;
  • notification or handoff expectation supported by the host.

Useful questions

  • What exact change counts?
  • How often is checking useful and proportionate?
  • When must monitoring stop?
  • How will an unavailable or stale source be reported?

Possible output

A bounded monitoring definition, current observation, change notification, or honest statement that recurring monitoring is unavailable.

Safety

Do not create an indefinite background process, daemon, or hidden notification channel. Use only monitoring capabilities the current host actually provides.

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.

monitor is an agent published in the GitHub repository jasonhnd/life_OS (5 stars, last pushed 25d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 226 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
