testland/spdx-format

Reference for the SPDX (Software Package Data Exchange) v2.3 + v3.0 SBOM specification - Linux Foundation-curated, license-focused format covering packages, files, snippets, relationships, license declarations, and (in 3.0) AI / dataset / build / security profiles; supports Tag-Value / JSON / YAML / RDF / Spreadsheet encodings; preferred by US Federal procurement (NIST guidance) and Linux distros. Use when the team's SBOM consumer requires SPDX format (federal procurement, Linux Foundation members, license-compliance focus).

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured reference skill with executable code, a validated workflow, and clean one-level-deep progressive disclosure. Its main weakness is redundancy: the generation flow is restated across the How-to summary, the numbered Steps, and the Worked example.

Suggestions

Collapse redundancy between "How to use", the Step 1–7 expansions, and the "Worked example" — e.g., make the Worked example reference the Steps by number instead of re-narrating them, saving ~15–20 lines.

Trim the "SPDX is the Linux Foundation's SBOM standard, originally focused on license compliance" opener in the Overview, which restates facts already implied by the description and the version table.

DimensionReasoningScore

Conciseness

The body is mostly tight (tables and code over prose), but the same generation workflow is walked three times — the "How to use" summary, the expanded Steps 1–7, and the "Worked example" — so not every token earns its place.

2 / 3

Actionability

It provides executable, copy-paste-ready artifacts: a full SPDX 2.3 JSON document, the `pyspdxtools --infile sbom.spdx.json --version SPDX-2.3` command, a Tag-Value block, and a complete GitHub Actions YAML job.

3 / 3

Workflow Clarity

A clear seven-step sequence is given with an explicit validation checkpoint (Step 6, `pyspdxtools` structural + license-expression checks) and a validate→fix retry path noted in the anti-patterns table.

3 / 3

Progressive Disclosure

The body is an overview that signals a single one-level-deep reference — `references/spdx3-profiles-and-tooling.md` (verified present) — linked at Step 5 and in References, with the detailed 3.0 profile/tooling content correctly split out rather than inlined.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A dense, well-constructed description that covers what the reference provides, when to invoke it, and the natural trigger terms a user would say, with a clear SPDX niche distinct from sibling SBOM skills. It is long but every clause carries concrete information rather than fluff.

DimensionReasoningScore

Specificity

The description enumerates concrete coverage areas ("packages, files, snippets, relationships, license declarations, and (in 3.0) AI / dataset / build / security profiles") plus five encodings, listing multiple specific concrete items rather than vague claims.

3 / 3

Completeness

It states what the skill is ("Reference for the SPDX... specification") and gives an explicit when clause ("Use when the team's SBOM consumer requires SPDX format (federal procurement, Linux Foundation members, license-compliance focus)"), answering both questions.

3 / 3

Trigger Term Quality

It surfaces natural terms a user would actually say — "SPDX", "SBOM", "federal procurement", "license-compliance", and "Linux Foundation" — giving good coverage of likely request phrasings.

3 / 3

Distinctiveness Conflict Risk

The SPDX-specific scope and concrete triggering contexts (federal procurement, Linux Foundation, license compliance) make it unlikely to fire for sibling SBOM skills like cyclonedx-format or syft-generation.
