+### 2026-10-30: Antigravity CLI 1.4.10, macOS 15.6 arm64
+
+- Plugin commit `83e4be0`, skills pin `59945da`.
+- CodeRabbit CLI 0.9.1, already installed and signed in.
+- Surface: Antigravity CLI print mode (`agy -p`) with the default model.
+
+Discovery (steps 1 to 3 and 5):
+
+- `agy plugin install https://github.com/coderabbitai/antigravity-plugin` in a
+  separate profile installed two skills (`coderabbit-autofix`,
+  `coderabbit-review`), two agents (`coderabbit-autofix-planner`,
+  `coderabbit-reviewer`), and one rule (`coderabbit-review-routing`).
+- `agy plugin validate --strict .` passed. Its only note is the missing logo.
+- The review run loaded a workspace copy from `.agents/plugins/` with a test-only
+  manifest name, because an installed Marketplace `coderabbit` plugin uses the
+  same plugin name. The Marketplace plugin was disabled during the run.
+
+Review (steps 1 to 3 and 5):
+
+- A disposable repository had two known bugs in one tracked file: an off-by-one
+  loop bound and an assignment inside a lookup predicate.
+- Prompt: review uncommitted changes with CodeRabbit, list every finding with its
+  severity, and do not edit files.
+- The agent read the routing rule, the `coderabbit-review` skill, and
+  `references/auth-recovery.md`. It ran `git status`, `git diff`,
+  `auth status --agent`, and `review --agent --uncommitted`, which took 80 seconds.
+- CodeRabbit returned two `major` findings, one for each bug. The agent reported
+  both with native severity, completion status, and the proposed diffs. No files
+  changed.
+
+Headless permission finding:
+
+- The bundled guidance runs the CLI through a quoted absolute path. Antigravity
+  allow rules did not match the quoted command name, so print mode denied
+  `review --agent` even with explicit allow rules. Interactive sessions show an
+  approval prompt instead.
+- The recorded run told the agent to use the same absolute path without quotes.
+  Headless or CI use needs either that change or an interactive approval.
+
+Not run: slash command availability (step 4 of Discovery), sign-in handoff, fixes
+and re-review, untracked files, failed or partial reviews, all existing PR
+feedback steps, and the Antigravity App and IDE surfaces.

 - `coderabbit auth login --agent` supports browser OAuth through a local callback. It cannot combine with `--api-key` or `--self-hosted`; never ask for pasted OAuth tokens.
 - `coderabbit auth login --region eu` selects EU SaaS login. Saved region is reused for reviews. Review-level `--region us|eu` requires inline `--api-key <key>`; it is not how to select an existing EU browser login. Keep secrets out of transcripts and shell history.
 - `coderabbit auth org` switches organizations for an existing browser login. `auth org --agent` lists organizations for agent consumption; it does not select one. API-key and self-hosted modes do not support this organization switch.
-- `coderabbit usage` and `coderabbit review --usage` display account usage. Do not promise structured `usage --agent` output. `--use-credits` on review authorizes additional credit spending; add it only when that spending is authorized.
 - `coderabbit doctor`, `coderabbit stats` (optionally `--rebuild`), and `coderabbit update` are human-oriented diagnostic, statistics, and update commands. `coderabbit skills` is an interactive install/update flow, not an unattended `skills add` command. Do not invent a `feedback` command.
 
+## Usage and paid continuation
+
+- Run `coderabbit usage --agent` to check review allowance, billing usage, and available credit/cap information. Missing or unavailable credit/cap fields mean unknown, not zero. If the installed version lacks `--agent`, use `coderabbit usage`.
+- When a review returns `action_required` with `status: "awaiting_confirmation"` for paid continuation, neutrally explain the returned offer, including its billable file count and maximum cost, before an authorized retry. Retry the same review with `--use-credits`, preserving `--agent`, its directory, and scope flags.
+- `--use-credits` on review authorizes additional credit spending; add it only when that spending is authorized.

 ## Local configuration
 
 `coderabbit config` guides a human through local configuration. On binaries supporting agent protocol 2, `config --agent` inspects without writing, and `config --agent --generate` proposes YAML without applying it. `--profile chill|quiet|assertive|default` implies agent generation; `quiet`, `chill`, and `assertive` are review profiles; `default` is a CLI reset selector, not a YAML profile. Validate against the current fetched schema. `--detailed` is a human wizard option and conflicts with `--agent`.
