At a glance

Read and compare finished harness runs - frame-time tails, utilization, chunk latency, JFR waits, load phases - and look them up in Grafana.

  • Asked what a run shows
  • Calls python3
  • Whether a change helped
  • Why a frame is slow

What it does

Analyze Run is an agent skill from xD3I/PZ_Optimization. Read and compare finished harness runs - frame-time tails, utilization, chunk latency, JFR waits, load phases - and look them up in Grafana. Use when asked what a run shows, whether a change helped, or why a frame is slow.

Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Monitoring and alerting. It works with Grafana. The repository describes itself as: Project Zomboid Build 42 performance work: class overrides, harness, findings.

When your agent uses it

  • Asked what a run shows
  • Whether a change helped
  • Why a frame is slow

Example prompts

  • “/analyze-run”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit f6eb39a. 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

    Shell commands in SKILL.md call:

    • python3

    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

Analyze Run loads about 536 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 147 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~536

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 147 words (~536 tokens).

“Always report frame-tail consistency (mean, p99, p99.9, max, spikes > 33 ms, jitter) AND utilization (cpu_pct, gpu_pct from sysmon) over the route window. Idle hardware below 240 fps is a finding.”
