Decision Log Adr Tracer

Decision Log & ADR Tracer

Audit repositories for undocumented architectural or technology shifts.

When to Use

• Dependency manifest changes
• PR or MR reviews
• CI checks for architecture governance
• Reviews of new frameworks, databases, or major libraries

Scope

• Scans: dependency manifests, imports that imply a new major technology, and decision-log or ADR locations such as docs/adr, docs/decisions, DECISION_LOG.md, architecture.md, and equivalent records.
• Exclusions: minor dependency bumps, editorial-only documentation edits, and changes that do not alter architecture materially.
• Fallback: if documentation structure is unclear, apply the shared conventions heuristic order and emit warning with low confidence.
• Routing: defer living guidebook freshness to Automated Software Guidebook Generator and explicit rule enforcement to Automated Architecture Governance.

Workflow

1. Detect technology shifts.
   • Inspect package manifests such as package.json, pom.xml, requirements.txt, go.mod, and similar files.
   • Scan imports and references for new major frameworks, databases, or third-party libraries.
2. Validate documentation.
   • Check docs/adr/, DECISION_LOG.md, architecture.md, or equivalent decision records.
   • Confirm the entry explains context, rationale, alternatives, and trade-offs.
3. Report gaps.
   • Flag new major technology with no matching ADR or decision-log entry.
   • Flag incomplete decision records that do not explain why the choice was made.

Rules

• Use static analysis only.
• Prefer deterministic signals from manifests and docs over inference.
• Treat minor version bumps and routine maintenance as out of scope unless they change architecture materially.
• If a new dependency is clearly structural, require documentation.

Shared Conventions

• Follow the repository-wide conventions in shared-skill-conventions.
• Use the canonical output contract, severity levels, confidence rubric, routing rules, and false-positive downgrades defined there.
• If this skill is not the closest match, defer to the routing guidance in the shared conventions file.

Output

Return a concise compliance report with:

• Detected technology shifts
• Matching ADR or decision-log entries
• Missing or incomplete documentation
• A draft ADR template when documentation is absent
