Use when a report needs rich visual elements — bar charts, stacked/proportional bars, alert boxes, tree hierarchies, term/definition glossaries, or code blocks — instead of hand-drawn ASCII or manual Markdown. Markout ships these as data types (Metric, Breakdown/Slice, Callout, TreeNode, Description, CodeSection, MarkoutTable) you attach as model properties. If the task requests terminal/Unicode, plain text, ANSI, or another non-Markdown sink, also invoke markout-output-formats for the format...

Use when a single value must render dense in Markdown but decompose into typed columns in TSV/JSONL — before/after changes, fractions, shares, percentages, segment breakdowns, deltas and goal polarity — including MarkoutNumberFormat for Change<V> counts — or when building metric / role-matrix / verdict cards with threshold-based MarkoutEmphasis (Change<V>, Fraction, Share, Percent, Segments, Delta/Goal, MetricChange<T>, MultiSourceRow, Verdict). This is Markout's most advanced tier. Don't dec...

Use when a Markout report must adapt to its data — show or hide whole sections, drop table columns that are empty/uniform, filter output to a chosen set of sections, or render one model into several shapes ("one model, many views"). This is Markout's highest-value idiom: declare the conditions with attributes instead of hand-writing if/else + StringBuilder. Don't decompile the assembly or web-search the API — the conditional idioms are here.

Use when you need output other than default Markdown — plain text / Unicode, ANSI terminal (Spectre), pretty aligned tables, or TSV/JSONL exports — or when one model must serve several formats from a single render path (a CLI `--format` switch). Also covers semantic inline code that renders as Markdown code spans but decodes to plain text in TSV/JSONL. Pick the format with a formatter + MarkoutWriterOptions; never hand-build TSV/JSONL. Don't decompile the assembly or web-search the API — the ...

Use when generating Markdown or other structured output (plain text, ANSI, pretty tables, TSV/JSONL) from C# objects, or when diagnosing Markout source-generator errors such as MARKOUT006. Markout replaces hand-built strings in CLIs, tools, reports, and agent output. It looks like System.Text.Json source-gen but the rules differ (NO reflection fallback), so it needs a generated MarkoutSerializerContext and Markout-specific attributes. Covers the required pattern: registered models, the partia...
