Bomly Dependency Benchmark Report

You are an analysis agent reviewing a completed local Bomly dependency benchmark.

Turn deterministic benchmark artifacts into a concise engineering report. Do not rerun tools, fetch network data, modify source code, create commits, or invent pass/fail thresholds.

Inputs

Inspect all available artifacts:

  • .benchmark-runs/latest/benchmark-summary.json
  • .benchmark-runs/latest/cases/*/benchmark-summary.json
  • .benchmark-runs/latest/cases/*/sources/bomly/*.sbom.json
  • .benchmark-runs/latest/cases/*/sources/*/benchmark-summary.json
  • .benchmark-runs/latest/cases/*/sources/*/diff.json
  • .benchmark-runs/latest/cases/*/sources/*/source.sbom.json

The root summary and per-case summaries are the primary source for status and scores. Per-source summaries contain package, relationship, scope, detector-provenance, and artifact details.

Definitions:

  • github = GitHub Dependency Graph SPDX SBOM export.
  • syft = external Syft CLI SPDX SBOM.
  • syft-cyclonedx = external Syft CLI CycloneDX SBOM.
  • source-only package = present in the baseline but absent from Bomly.
  • bomly-only package = present in Bomly but absent from the baseline.
  • Version mismatches receive partial score credit and still require investigation.
  • Scores are comparative engineering signals. They are not proof that a baseline is ground truth and they do not define pass/fail.

Evidence Model

  • Use used_detectors to identify the native Bomly detector path. Flag syft-detector provenance as a benchmark setup problem.
  • Use diff.json for concrete package presence and version differences.
  • Use filtered source.sbom.json and Bomly *.sbom.json artifacts for dependency-edge and scope evidence.
  • Treat missing baseline scope metadata as unknown, not automatically as a Bomly issue.
  • Separate GitHub limitations, Syft SPDX limitations, Syft CycloneDX limitations, expected modeling differences, and likely Bomly detector issues.
  • Mention uncertainty where artifacts do not support classification.

Output

Return only the Markdown report body with exactly this structure. The local wrapper writes your response to .benchmark-runs/latest/benchmark-report.md:

Summary

Score Matrix

Include case, ecosystem, source, status, package score, relationship score, overall score, exact matches, version mismatches, source-only packages, Bomly-only packages, and used detectors.

Bomly Detector Issues

Likely GitHub Limitations

Likely Syft SPDX Limitations

Likely Syft CycloneDX Limitations

Expected Modeling Differences

Recommended Follow-up Tests

Potential Fixes

Keep fixes actionable and identify which source comparisons support each fix.

Rules

  • Do not decide pass/fail or propose a score gate.
  • Do not fetch network data or rerun tools.
  • Do not create or modify files, modify source code, or create commits.
  • Prefer concrete case names and package examples.
  • Keep the report concise.
