Release Note

• No release needed (docs/chore/test-only/private package)
• Changeset added via pnpm changeset (select packages + bump)
  • Bump type: Patch / Minor / Major (choose patch for all if unsure)
  • Packages: ...

Summary by CodeRabbit

• New Features

  • Added /init command to analyze the codebase and generate or improve AGENTS.md documentation.

• Improvements

  • Unified prompt-command handling so non-streaming results follow the same streaming pipeline for consistent messaging and to avoid duplicate outputs.
  • Added an integration hook to allow external routing of prompt commands into the streaming flow.

📝 Walkthrough

Walkthrough

Removes a comment in the CLI config, adds an OverlayContainer prop to route prompt commands into the InputContainer pipeline, updates OverlayContainer callbacks, and introduces a new /init interactive command that creates or improves an AGENTS.md at the repository root. Also adds a changeset for @dexto/tui.

Changes

Cohort / File(s)	Summary
CLI entry packages/cli/src/index-main.ts	Minor comment removal around the enriched configuration's logLevel field; no behavioral change.
TUI overlay & routing packages/tui/src/containers/OverlayContainer.tsx	Adds new prop onSubmitPromptCommand?: (commandText: string) => Promise<void>, routes non-streaming sendMessage results through that callback instead of local immediate emission, and updates related useCallback dependency arrays.
Interactive commands packages/tui/src/interactive-commands/general-commands.ts	Adds a new init general command that builds a prompt asking the system to analyze the repo and create or improve AGENTS.md at process.cwd()/AGENTS.md, returning a send-message marker.
Changeset .changeset/sharp-trams-smash.md	Adds a patch changeset for @dexto/tui describing the new /init command.

Poem

🐰 I nibble code and send a ping,
A prompt now routed like a spring,
Init will scan the roots and write,
AGENTS.md to guide the light,
Hooray — I hop, and all connects! ✨

Inline comments:
In `@packages/cli/src/index-main.ts`:
- Around line 840-853: The CLI's DEXTO_LOG_LEVEL parsing is only applied in the
top-level main path; extract that logic into a shared resolver function (e.g.,
resolveDextoLogLevel or getEnvLogLevel) and replace the inline parsing with a
call to it where you build agent config (the enrichAgentConfig call) and inside
bootstrapAgentFromGlobalOpts so both call sites use the same resolved logLevel
instead of hardcoded 'info'/'error'; ensure the resolver reads
process.env.DEXTO_LOG_LEVEL, normalizes to lowercase, validates against
['debug','info','warn','error'], and returns the validated level (default
'info') so enrichAgentConfig and bootstrapAgentFromGlobalOpts consume the same
value.

In `@packages/tui/src/containers/OverlayContainer.tsx`:
- Around line 1255-1263: The code routes the literal commandText to
onSubmitPromptCommand, which re-submits the slash command instead of the
resolved prompt; change the call to pass the resolved payload
(result.messageToSend) so the generated prompt is submitted: await
onSubmitPromptCommand(result.messageToSend). Also ensure the no-callback path is
not a no-op—if onSubmitPromptCommand is undefined, forward result.messageToSend
into the existing InputContainer send pipeline (the same flow used for normal
user messages) so the resolved prompt is processed even without a callback.
