# Changelog

All notable changes to Flynn are documented in this file.

## [Unreleased]

### Added

- **CLI Surface** -- Full command-line interface via `flynn` binary with 6 commands:
  `start`, `tui`, `send`, `sessions`, `doctor`, `config`
- **Doctor Diagnostics** -- `flynn doctor` validates config, YAML parsing, schema,
  env vars, data directory, session DB, model config, Telegram, MCP servers, and skills
- **Cron Scheduling** -- `automation.cron` config for scheduled agent messages with
  output channel routing (e.g. fire a prompt at 9 AM, send the response to Telegram)
- **CronScheduler Channel Adapter** -- Implements `ChannelAdapter` interface for
  cron-triggered messages through the standard agent pipeline
- **CLI Shared Utilities** -- Config loading, data dir resolution, secret redaction,
  status formatting for all CLI commands
- **CronJobConfig Type Export** -- `CronJobConfig` type available from `config/index.ts`

### Changed

- **Entry Points Refactored** -- `src/index.ts` and `src/tui.ts` now delegate to
  the CLI module (`src/cli/index.ts`) instead of directly starting the daemon/TUI
- **Daemon Wiring** -- CronScheduler auto-registers in the channel registry when
  `automation.cron` jobs are configured
