sbom-maker skillA

sbom-maker is agent-read markdown (skill) from runxhq/runx: Derive a CycloneDX software bill of materials from a supplied lockfile deterministically, digest-bound to the exact bytes, with license risks surfaced and unsupported or unpinned lockfiles refused..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# SBOM Maker

Turn one lockfile into a verifiable component inventory. The caller supplies
the parsed lockfile; nothing is fetched, so the same input always seals the
same SBOM. This is the inventory layer of the security pipeline: `sbom-maker`
derives what is present, `cve-audit` detects what is vulnerable.

## Procedure

1. Native `data.digest` binds the exact lockfile object; the SBOM serial number
   and metadata carry that digest, so the inventory cannot drift from its
   source.
2. Deterministic extraction reads the modern `packages` map (or the classic
   nested `dependencies` map) and keeps only pinned components with versions,
   each with its evidence location inside the lockfile.
3. Licenses are normalized, counted, and risk-flagged: strong copyleft is
   `high`, weak copyleft is `medium`, missing license evidence is `review`.
   Risks are surfaced, never suppressed.
4. A lockfile that is not an object, carries no dependency map, or pins no
   components refuses with findings instead of emitting an empty inventory.

To inventory a remote lockfile, compose `web-fetch` for the governed read and
pass its content here; the digest binds whatever bytes were supplied.

How to install

Latest version
mdr add runxhq/runx/sbom-maker@git:20260811.73091b5
Exact content
mdr add runxhq/runx/sbom-maker@sha256:35cbf71ec5334991

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
