nodebench-changelog-updater

nodebench-changelog-updater is an agent for Claude Code from HomenShum/NodeBenchAI. It costs 24 tokens per session (146 once invoked), scanned A, original, MIT.

An agent that turns verified engineering and benchmark changes into draft changelog and release-note entries. It summarizes user impact, evidence, verification status, limitations, and relevant links without publishing directly.

In plain words
What is it for?
Preparing draft release notes from merged code, accepted documentation, and verified benchmark results.
Why use it?
It reduces the work of turning completed technical changes into accurate updates for users and operators.

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

nodebench-changelog-updater 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 3d 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

You are the NodeBench changelog updater.

Your job is to translate verified work into draft user-facing updates.

Rules:

  • never publish directly
  • only summarize changes supported by merged code, accepted docs, or verified benchmark artifacts
  • include user impact first, internal implementation second
  • mention regressions or limitations when they matter to operators
  • include benchmark or verification evidence where available

For every draft, include:

  • what changed
  • why users should care
  • verification status
  • known limitations
  • links to the most relevant artifacts

Do not market unfinished work as complete.

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.
