### Tags

feature-flags, progressive-delivery, canary-release, rollout, mcp, launchdarkly, release-management

### Key Features

- Automatic rollout detection – Injects progressive-delivery doctrine at each Spec Kit phase (specify → clarify → plan → tasks → analyze → checklist → implement)
- Zero new commands – All functionality integrates into existing Spec Kit workflow via before_* hooks
- Self-gating hooks – Each phase checks for a rollout marker in spec.md; skips if not needed
- LaunchDarkly provider (V1) – Native support for LaunchDarkly feature flags
- MCP integration – One-time /speckit.rollout.connect setup wires LaunchDarkly MCP server

### Testing Checklist

- [x] Extension installs successfully via download URL
- [x] All commands execute without errors
- [x] Documentation is complete and accurate
- [x] No security vulnerabilities identified
- [x] Tested on at least one real project

### Submission Requirements

- [x] Valid `extension.yml` manifest included
- [x] README.md with installation and usage instructions
- [x] LICENSE file included
- [x] GitHub release created with version tag
- [x] All command files exist and are properly formatted
- [x] Extension ID follows naming conventions (lowercase-with-hyphens)

### Testing Details

- Install the extension with `specify extension add rollout` in a Spec Kit project → confirm it installs and validates cleanly, with all commands and hooks registered.
- Run `/speckit.rollout.config` with a LaunchDarkly MCP server already registered in your client → confirm you're walked through provider/project/environment selection and end up with a written config block, with no MCP command or credential stored anywhere.
- Run `/speckit.specify Add a dark mode toggle in settings, controlled by a feature flag` → check that `spec.md` gets a `## Delivery Considerations` section naming a candidate boolean flag (e.g. `dark-mode-enabled`).
- Run `/speckit.plan` on the dark-mode spec → check that `plan.md` gets a `## Delivery Strategy` section (flag name, phased rollout, targeting, telemetry gates, rollback conditions).
- Run `/speckit.tasks` → check that `tasks.md` gets concrete rollout tasks, including one to create the `dark-mode-enabled` flag in LaunchDarkly, plus configuring environments/targeting, integrating the SDK, adding telemetry, and defining rollback.
- Run `/speckit.implement` on the dark-mode feature with an MCP server registered and configured → confirm the `dark-mode-enabled` flag creation task is executed and the flag now exists in your LaunchDarkly project (check the LaunchDarkly dashboard or ask the agent to read the flag status back).

### Example Usage

```markdown
- Install the extension with `specify extension add rollout` in a Spec Kit project → confirm it installs and validates cleanly, with all commands and hooks registered.
- Run `/speckit.rollout.config` with a LaunchDarkly MCP server already registered in your client → confirm you're walked through provider/project/environment selection and end up with a written config block, with no MCP command or credential stored anywhere.
- Run `/speckit.specify Add a dark mode toggle in settings, controlled by a feature flag` → check that `spec.md` gets a `## Delivery Considerations` section naming a candidate boolean flag (e.g. `dark-mode-enabled`).
- Run `/speckit.plan` on the dark-mode spec → check that `plan.md` gets a `## Delivery Strategy` section (flag name, phased rollout, targeting, telemetry gates, rollback conditions).
- Run `/speckit.implement` on the dark-mode feature with an MCP server registered and configured → confirm the `dark-mode-enabled` flag creation task is executed and the flag now exists in your LaunchDarkly project (check the LaunchDarkly dashboard or ask the agent to read the flag status back).

### Additional Context

_No response_

Start by locating the extension catalog and its existing entry format, then compare it with the proposed Rollout catalog entry and the extension.yml manifest mentioned here. Validate the catalog change by running `specify extension add rollout` and confirming the commands and hooks register cleanly; done means the Rollout entry is present and installation succeeds.
