Adds a third output format. Under markdown the engine calls the same `human(ui)` thunk once, never calls the `stdout` thunk, renders every block as plain Markdown on stdout, and writes nothing to stderr. Colour is off even with `--color`, `Ui.width` is unbounded, and every `=== "human"` check in `engine.ts` and `settleVersion` now sends markdown down the human path. The renderer lives in `execution/markdown.ts` beside `rendering.ts`; `markdown.test.ts` pins every block kind, next-action bullet, the diagnostic shape, the sections, and the blank-line rule byte-for-byte. Errored runs, `--version`, child status, live events, help, docs, and the engine version bump follow in later dispatches.

… and config warnings Under `--format markdown` every remaining non-help surface now prints on stdout and stderr stays empty. An errored run prints the error in the diagnostic shape, then `### Diagnostics` for the accompanying findings; `--version` prints the bare version; a child-status settlement prints its next actions as bullets; live events print one line each (`step-started`, `progress`, and `remediation` dropped, `step-finished` as `[outcome] step`, the rest as human); config-section warnings of an OK run print in the diagnostic shape before the blocks. `commentaryLine` in `rendering.ts` is now the one source for the endpoint, status, and artifact lines, so the two renderers cannot drift.

The warnings section is separated from whatever the run prints next (blocks, an error, or nothing) by exactly one blank line, per the spec's config-section warnings rule.

`help.ts` is now a `HelpCard` data model (header, usage, description, and every section as rows) plus the terminal renderer, byte-identical to before; `markdown.ts` gains `renderHelpMarkdown`, which draws the same card as headings, paragraphs, pipe tables, and bash fences per the spec's help shape. `--help`, `-h`, `--help-all`, and bare group invocations route to it under `--format markdown`, on stdout with stderr empty. The bareness check now ignores the format-selection flags, so `cli project --format markdown` is the group's help rather than an unknown-command error. Terminal help for a root, a group, and a leaf card was captured before the split and is pinned in `help-terminal.test.ts`; the Markdown output for the same cards is pinned in `help-markdown.test.ts`.

…bare `withoutFormatFlags` dropped a `--format` token whatever followed it and scanned past `--`, so `cli --format`, `cli project --format=bogus`, and `cli --format project` printed help and exited 0 instead of the usage error they gave before. It now strips `--format=<v>` and `--format <v>` only when `<v>` is a recognised format, and stops at a bare `--`, keeping it and everything after it.

`docs/product/output-conventions.md` gains a `--format markdown` section, the style guide's flag list names the third format, and the engine README names the three formats and their purposes. `pnpm bump-cli-engine-version minor` moves the engine from 0.3.0 to 0.4.0 and repins `@prisma/cli` and `prisma` to it. The tarball conformance check `engine-pin-mismatch` will fail until `@prisma/composer-cli` and `@prisma/orm-toolchain` republish against 0.4.0; that is the known merge blocker for this PR.

Select backtick delimiters from the rendered content.
The fixed delimiters produce malformed Markdown when a command, help value, example, or drawing contains the same backtick sequence. For example, a drawing containing four backticks closes the selected four-backtick fence.
Use shared code-span and code-fence helpers. Select a delimiter longer than the longest backtick run in the content. Add regression tests for commands and drawings that contain backticks.
Also applies to: 99-99, 105-105, 111-112, 281-281, 308-308, 332-332

Escape existing backslashes before table pipes.
For input such as a \| b, this replacement produces two backslashes before the pipe. The first backslash escapes the second, so the pipe can become a table delimiter.
Escape backslashes first. Add a regression test for this input.
Proposed fix
function escapeCell(text: string): string {
- return text.replace(PIPE, "\\|").replace(NEWLINE, " ");
+ return text
+ .replace(/\\/g, "\\\\")
+ .replace(PIPE, "\\|")
+ .replace(NEWLINE, " ");

Give --format precedence over --json during pre-parsing.
applySharedFlags gives shared.format precedence over shared.json. This function instead returns the first recognized selector.
For --json --format markdown --help, the help path selects JSON and writes terminal help to stderr. A mounted command selects Markdown. This makes format behavior depend on whether the command reaches parsing.
Scan for an explicit --format value first. Use --json only when no explicit format exists. Add a regression test for both flag orders.

Adds a third output format,
--format markdown, to@prisma/cli-engine. It renders the same blocks a command already describes for the terminal as plain Markdown, for agents that read CLI output as text. No command changes and no command can tell the format apart.Changes
presentation.ts,shared-flags.ts,pre-parse-argv.ts):Formatishuman | json | markdown;--format markdownand--format=markdownselect it. No shorthand flag. Default selection is unchanged: a terminal getshuman, a pipe getsjson; markdown is only ever explicit.command-context.ts,settlement.ts,reporting.ts,needs.ts,engine.ts): under markdown the blocks, next actions, diagnostics, structured errors, config-section warnings, help,--version, and live events all print on stdout and the engine writes nothing to stderr. The raw data lines a command publishes for pipes are not printed, because the Markdown table already carries them. Colour is off even with--color, and the command'sUireports an unbounded width.execution/markdown.ts): one rule per block kind.[status] textsummaries,label: valuelines, GFM pipe tables with|escaped and headers sentence-cased,-bullets, nested bullets for trees, fenced code for drawings. Structured errors and diagnostics render as[severity] CODE: summary, thenwhy:,where:, next actions as bullets with the command in backticks, anddocs:. Livestep-startedandprogresslines are dropped;step-finishedrenders as[outcome] step; the other event lines are the same text the terminal prints.help.ts): split into aHelpCardmodel plus two renderers. The terminal renderer is byte-identical to before, pinned by tests generated from the pre-refactor build. The Markdown renderer prints a heading, the usage in abashfence, and the commands, arguments, options, and workflow as pipe tables.docs/product/output-conventions.md,docs/product/cli-style-guide.md, and the engine README name the third format. The engine is bumped to 0.4.0.Why
jsoncosts an agent tokens on the envelope and repeated keys;humancarries padding, rails, glyphs, and colour that a model cannot use. Markdown gives a model every value labelled, one entity per block, tables only for uniform rows, and no decoration. Because every command already describes its output as blocks, one renderer serves every CLI on the engine at once.Markdown goes to stdout, unlike the terminal format, because an agent asking for it is asking for the document, the same way
--format jsonputs the whole envelope on stdout. Keeping it on stderr would have handed the agent the Markdown table and the same rows again as tab-separated data lines.Behaviour change outside markdown
A bare group invocation stays bare when the only extra tokens select a format, for every format.
prisma project --jsonnow prints group help on stderr and exits 0 instead of failing withCLI.UNKNOWN_COMMAND, matching what a bareprisma projectalready did. A malformed or missing format value still reaches routing and fails as before.Merge blocker
The engine bump to 0.4.0 fails the tarball conformance
engine-pin-mismatchcheck until@prisma/composer-cliand@prisma/orm-toolchainrepublish against 0.4.0. That release chain is a separate step.Verification
