rocrate-metadata-bundle-starter

rocrate-metadata-bundle-starter is a skill for Claude Code, Codex from ma-compbio-lab/SkillFoundry. It costs 0 tokens per session (310 once invoked), scanned A, original, Apache-2.0.

A tool for packaging one local data file as an RO-Crate, a folder format that stores data together with machine-readable information about its contents and origin.

In plain words
What is it for?
Use it to create starter data bundles, test fixtures, or demos with a root dataset, measurement metadata, and a summary of the generated metadata graph.
Why use it?
It provides a repeatable way to bundle a file with provenance information, so people and software can understand where the data came from and what the bundle contains.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./slurm/envs/data-tools/bin/python skills/data-acquisition-and-dataset-handling/rocrate-metadata-bundle-starter/scripts/build_rocrate_metadata_bundle.py \.

Good fit Use it to create starter data bundles, test fixtures, or demos with a root dataset, measurement metadata, and a summary of the generated metadata graph.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

rocrate-metadata-bundle-starter 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 7d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/build_rocrate_metadata_bundle.py, tests/test_build_rocrate_metadata_bundle.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

RO-Crate Metadata Bundle Starter

Use this skill to package a small local data file into an RO-Crate directory with basic provenance-rich metadata and a compact summary of the generated graph.

What it does

  • copies one local data file into a fresh RO-Crate directory
  • writes ro-crate-metadata.json with a named root dataset and measurement metadata
  • reports the crate path, graph entity counts, and bundled data files

When to use it

  • you need a verified starter for data-provenance-tracking
  • you want a lightweight pattern for packaging outputs with reusable metadata
  • you need a deterministic RO-Crate fixture for tests or demos

Example

./slurm/envs/data-tools/bin/python skills/data-acquisition-and-dataset-handling/rocrate-metadata-bundle-starter/scripts/build_rocrate_metadata_bundle.py \
  --input skills/data-acquisition-and-dataset-handling/rocrate-metadata-bundle-starter/examples/toy_measurements.csv \
  --crate-dir scratch/rocrate/toy_bundle \
  --summary-out scratch/rocrate/toy_bundle_summary.json

Verification

  • Skill-local tests: python3 -m unittest discover -s skills/data-acquisition-and-dataset-handling/rocrate-metadata-bundle-starter/tests -p 'test_*.py'
  • Expected summary: has_metadata_file == true, data_entity_count == 1, root_dataset_name == "Toy Measurement Bundle"
Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

rocrate-metadata-bundle-starter is a skill published in the GitHub repository ma-compbio-lab/SkillFoundry (38 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 310 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
