 ## [Unreleased]
 
+### Added
+- **`commit` command — generate a commit message and commit (ADR-0019).**
+  `commitbrief commit` reads the staged diff, asks the configured provider for
+  a commit message, shows it for confirmation, and — on Yes (the default) or
+  `--yes` — runs `git commit`. This is the first path where the tool writes to
+  git; everything else stays read-only (PRD NG4 is rescoped to the review
+  path). Highlights:
+  - `--type` / `-t` picks the format: `plain` (default), `conventional`,
+    `conventional+body`, `gitmoji`, `subject+body`.
+  - `--generate` / `-g <N>` offers N alternatives in an arrow-key selector
+    (capped at 10); a single provider call produces all N.
+  - `--provider` / `--model` / `--cli` select the backend exactly as for a
+    review; messages are always written in English regardless of `--lang`.
+  - The pre-send `.commitbrief/**` guard, secret scan, and cost preflight all
+    run on the staged diff before the call; the suggestion is cached.
+  - With no staged changes it errors clearly; a non-TTY run without `--yes`
+    errors (it cannot confirm). `--yes` commits the first suggestion.
+  - New config keys `commit.type` and `commit.generate` set the defaults
+    (precedence: flag > config > built-in). This complements the existing
+    `--suggest-commit` review flag, which is unchanged.
+
 ### Changed
 - **`--version` no longer prints the splash logo.** `commitbrief --version`
   now emits only the single `commitbrief vX.Y.Z (commit <sha>, built <iso-ts>)`

+### `commitbrief commit`
+
+Generate a commit message from the **staged** diff and, after you confirm,
+run `git commit`. This is the only command that writes to git — every
+review path is read-only.
+
+```sh
+commitbrief commit                          # suggest one message, confirm (default Yes), commit
+commitbrief commit -t conventional+body     # conventional subject + a generated body

+commitbrief commit --provider openai --model gpt-5.4-mini
+commitbrief commit --yes                     # CI/non-interactive: commit the first suggestion
+```
+
+- **`--type` / `-t`** — message format: `plain` (default), `conventional`,
+  `conventional+body`, `gitmoji`, `subject+body`.
+- **`--generate` / `-g <N>`** — produce N alternatives (1–10) and choose one
+  in an arrow-key selector. A single provider call generates all N.
+- **`--provider` / `--model` / `--cli`** — select the backend, same as a
+  review. Messages are always written in English regardless of `--lang`.
+- Defaults come from the `commit.type` and `commit.generate` config keys when
+  the flags are omitted (precedence: flag > config > built-in).
+- The pre-send `.commitbrief/**` guard, secret scan, and cost preflight run on
+  the staged diff before the call; the suggestion is cached.
+- With **nothing staged** it errors (stage with `git add` first). On a
+  **non-TTY** without `--yes` it errors, because it cannot show the confirm or
+  selector. `--yes` commits the first suggestion (it does **not** bypass the
+  secret scan or cost preflight).
+
+> The tool never auto-stages and never edits files — it only runs `git commit`
+> on changes you already staged, and only after you say Yes.

+commitbrief-commit - Generate a commit message from staged changes and commit
+
+
+.SH SYNOPSIS
+\fBcommitbrief commit [flags]\fP
+
+
+.SH DESCRIPTION
+Ask the configured provider for a commit message describing the currently staged diff, then — after you confirm — run \fBgit commit\fR\&.
+
+.PP
+Use --type to pick the message format and --generate N to be offered several alternatives to choose from. Provider selection (--provider / --model / --cli) and the pre-send guard, secret scan, and cost preflight all work exactly as they do for a review.
+
+.PP
+Needs an interactive terminal to confirm (or to pick from --generate alternatives); pass --yes to commit the first suggestion non-interactively.
+
+
+.SH OPTIONS
+\fB-g\fP, \fB--generate\fP=0
+	offer N alternative messages to choose from (default 1, or commit.generate config)
+
+.PP
+\fB-h\fP, \fB--help\fP[=false]
+	help for commit
+
+.PP
+\fB-t\fP, \fB--type\fP=""
+	commit message format: plain|conventional|conventional+body|gitmoji|subject+body (default "plain", or commit.type config)
+
+
+.SH OPTIONS INHERITED FROM PARENT COMMANDS
+\fB--allow-secrets\fP[=false]
+	bypass the pre-send secret scanner (use with care)
+
+.PP
+\fB--cli\fP=""
+	use a locally-installed CLI tool (claude|gemini|codex) as the review backend; shorthand for --provider -cli
+
+.PP
+\fB--color\fP="auto"
+	color output: auto, always, never
+
+.PP
+\fB--compact\fP[=false]
+	one-line per finding (dense review output)
+
+.PP
+\fB--copy\fP[=false]
+	copy findings (severity, path, title, description) to the system clipboard via OSC 52 + native tool
+
+.PP
+\fB-d\fP, \fB--dir\fP=[]
+	review only files under these directories (repeatable); combines with the active scope flag
+
+.PP
+\fB--fail-on\fP=""
+	exit 1 if any finding meets/exceeds severity (critical|high|medium|low|info|any|none)
+
+.PP
+\fB-f\fP, \fB--file\fP=[]
+	review only these files (repeatable); combines with the active scope flag
+
+.PP
+\fB--json\fP[=false]
+	emit machine-readable JSON output
+
+.PP
+\fB--lang\fP=""
+	override output language (e.g. tr, en)
+
+.PP
+\fB--markdown\fP[=false]
+	emit plain markdown (no ANSI)
+
+.PP
+\fB--min-severity\fP=""
+	hide findings below this severity in the rendered output (critical|high|medium|low|info); --json and --fail-on still see the full set
+
+.PP
+\fB--model\fP=""
+	override configured model
+
+.PP
+\fB--no-cache\fP[=false]
+	bypass cache (read and write)
+
+.PP
+\fB--no-cost-check\fP[=false]
+	skip the pre-send cost estimate prompt
+
+.PP
+\fB-o\fP, \fB--output\fP=""
+	write output to file instead of stdout
+
+.PP
+\fB--provider\fP=""
+	override configured provider
+
+.PP
+\fB-q\fP, \fB--quiet\fP[=false]
+	suppress info messages on stderr
+
+.PP
+\fB--show-prompt\fP[=false]
+	print the exact system + user prompt that would be sent, then exit (no provider call, no cost)
+
