Support topics are small, candidate-scoped investigation guardrails injected into sub-agent briefs.
They are not recommendations, gates, scanners, or broad documentation. A topic tells the investigator what evidence to check, what false positives to avoid, and when to abstain for one class of candidate.
Add A Topic
Add one file: references/support-topics/<id>.md.
The filename must match the id. Frontmatter uses a strict subset of YAML: one key: value per line, arrays as JSON arrays.

Rules
Every active topic must cite only URLs or skill-rule refs already present in references/docs-library.json.
Use candidateKinds to keep the topic narrow. Use "*" only for workflow/protocol topics that truly apply to every candidate.
Use optional metrics only when a topic applies to a specific candidate metric, such as ["LCP"], ["INP"], or ["CLS"] for Core Web Vitals.
Use optional routePatterns as JavaScript regex source strings when a topic should appear only for specific candidate routes, such as ["(^|/)404$"].
Keep the body below maxBriefChars; the brief renderer caps selected topics before they reach the sub-agent.
Put URLs in frontmatter only. Topic bodies should describe checks and guardrails, not cite new sources.
Do not include internal repository paths, service names, pricing tables, exact savings claims, or framework APIs without version gating.
