update_powergridmodel is a command for Claude Code from datathings/marketplace. It costs 0 tokens per session (1,235 once invoked), scanned A, original, Apache-2.0.

An update command for the power-grid-model library, a software library for modeling electrical power grids. It also synchronizes the related skill files with the library's updated API.

In plain words
What is it for?
Use it to find the latest tagged library release, update the bundled repository, review changes, and refresh the power-grid-model skill.
Why use it?
It avoids manually fetching releases, comparing versions, updating the library checkout, and keeping its agent instructions aligned.

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

update_powergridmodel 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 4d 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.

Update power-grid-model Skill to Latest Version

This command updates the power-grid-model library to the latest version and synchronizes all skill files with the updated API.

Working directory: plugins/powergridmodel/

Repository Structure

plugins/powergridmodel/
├── skills/powergridmodel/          # Skill content (SKILL.md and references/)
├── power-grid-model/               # Upstream repo clone (NOT a submodule)
└── .claude-plugin/plugin.json      # Plugin manifest

The power-grid-model/ directory is a standalone git clone from https://github.com/PowerGridModel/power-grid-model — updated independently via git fetch and git checkout <tag>.

Process

1. Update Library to Latest Tag

cd plugins/powergridmodel/power-grid-model

git fetch --tags

CURRENT_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "unknown")
echo "Current tag: $CURRENT_TAG"

# Tags follow v#.#.# format (e.g., v1.13.10)
LATEST_TAG=$(git tag --sort=-version:refname | grep "^v" | head -n 1)
echo "Latest tag: $LATEST_TAG"

if [ "$CURRENT_TAG" != "unknown" ] && [ "$CURRENT_TAG" != "$LATEST_TAG" ]; then
  echo "Commits between $CURRENT_TAG and $LATEST_TAG:"
  git log --oneline "$CURRENT_TAG..$LATEST_TAG" | head -n 50
fi

git checkout "$LATEST_TAG"
echo "Now on: $(git describe --tags)"

cd ../../..

2. Analyze API Changes (subagent)

Dispatch a general-purpose subagent via the Task tool for the analysis and documentation rewrite. This keeps the large source content out of the main context.

Provide the subagent with:

  • Path to Python package: plugins/powergridmodel/power-grid-model/src/power_grid_model/
  • Path to skill references: plugins/powergridmodel/skills/powergridmodel/references/
  • Old tag and new tag (from Step 1 output)

The source of truth for the Python public API is:

  • src/power_grid_model/__init__.py — top-level exports
  • src/power_grid_model/core/power_grid_model.pyPowerGridModel class
  • src/power_grid_model/validation/ — validation functions
  • src/power_grid_model/enum.py — all enumerations
  • src/power_grid_model/component_attributes.py or equivalent — component definitions
  • Type stubs (.pyi) if present

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.
