process-stat-chart

process-stat-chart is a skill for Claude Code, Codex from chenchihcu/DevSpace-MCP. It costs 25 tokens per session (312 once invoked), scanned A, original, MIT.

A guide for defining statistical process control (SPC) charts, which track whether a process stays stable over time, along with related process statistics.

In plain words
What is it for?
Use it to plan control charts, process performance and capability measures such as Cp/Cpk, process stability indexes, and charts for unusual distributions.
Why use it?
It helps prevent charts from being disconnected from their source data, formulas, or limits. It also makes clear when missing data prevents a reliable conclusion.

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

process-stat-chart 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 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.

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

process-stat-chart

Purpose

Specify process statistics charts and reports while preserving statistical meaning and chart-to-data traceability.

When to Use

  • SPC, SPI, Cp/Cpk, control chart, or process abnormality reporting.
  • Planning chart specs before creating artifacts.
  • Reviewing whether chart conclusions are supported by data.

Inputs

  • Raw process measurements and units.
  • Sampling plan, subgrouping, limits, and time window.
  • Chart purpose and report audience.

Outputs

  • Chart specification.
  • Limit and formula checklist.
  • Data-to-chart traceability requirements.
  • Report summary with limitations.

Workflow

  • Confirm raw process data and subgrouping before chart conclusions.
  • Define chart type, axes, limits, and anomaly rules.
  • Keep process symptoms separate from root cause.
  • Pair charts with verification evidence.

Verification

  • Check chart source fields and formulas.
  • Check limits are defined and traceable.
  • Check labels, legends, and anomaly indicators are readable.

Risks / Limits

  • Missing raw process data blocks confirmed conclusions.
  • Visual-only chart changes must not alter formulas.
  • Capability interpretation requires appropriate data and assumptions.

Forbidden Actions

  • Do not change formulas without disclosure.
  • Do not present symptoms as root causes.
  • Do not read protected paths or secrets.

Example Task

Create a chart spec for SPI solder paste volume control charts with verification criteria.

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.
