pulse

pulse is an agent for Claude Code from isaacsight/kernel. It costs 0 tokens per session (1,014 once invoked), scanned A, original, MIT.

An agent that measures how a software project is performing by collecting usage, website, code, and learning-system signals. It turns those measurements into trend reports.

In plain words
What is it for?
Use it to track npm downloads, GitHub traffic and repository activity, recent commits, and kbot learning statistics.
Why use it?
It helps replace guesses about adoption and activity with observed data. It can show whether downloads, visitors, code changes, and learned patterns are rising or falling.

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

pulse 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 1mo 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.

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.

pulse is an agent published in the GitHub repository isaacsight/kernel (16 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,014 tokens. 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 2026-09-03.
