fix(server): pin the Claude CLI verbose setting for text generation

[sti0]

What Changed

makeClaudeTextGeneration now always sets verbose: false in the settings object it passes to --settings. Because the key is always present, the --settings payload now goes out on every call instead of only when thinking, fastMode or ultracode are set. Those three are otherwise untouched.

Tests: a new case for the pinned --settings {"verbose":false} with no other settings, a new case proving that streamed events fail loudly, and the existing fixtures' --settings expectations extended by verbose.

Three added lines of production code, the rest is tests.

Why

Text generation through the Claude CLI fails silently whenever the user has verbose enabled in their Claude settings. With verbose on, claude -p --output-format json prints an array of stream events instead of the flat { structured_output } envelope the decoder expects, so decoding dies with SchemaError: Expected object, wrapped in TextGenerationError: Claude CLI returned unexpected output format.

That error is only ever swallowed as a log warning, so nothing surfaces to the user. Thread titles, worktree branch names, commit messages and PR bodies just keep falling back to their placeholders (t3code/<hex>), permanently, with no indication why.

Pinning the setting is enough — no tolerant parsing of the event array is needed. Measured against Claude CLI 2.1.233, --settings beats both the user-level and the project-level settings:

call (user + project verbose: true)	output
without --settings	[{"type":"system",… — array
with --settings {"verbose":false}	{"is_error":false,… — flat object

The second test holds that assumption in place: if the CLI ever streams events despite the pinned setting, it fails loudly instead of silently.

Other providers are unaffected — Codex, Cursor, Grok and OpenCode parse the response text straight against the output schema, without an envelope.

Note

Low Risk
Small, localized CLI settings override for Claude text generation only; no auth, data, or provider-contract changes.

Overview
Stops Claude text generation from breaking when the user has CLI verbose enabled. User-level verbose made claude -p --output-format json emit a stream-event array instead of the { structured_output } envelope, so titles, branch names, commit messages, and PR bodies silently fell back to placeholders.

runClaudeJson now always includes verbose: false in --settings, so that flag is sent on every Claude CLI call (not only when thinking/fastMode/ultracode are set). Tests cover the always-on settings payload and fail loudly if the CLI still streams events.

Note

Pin verbose:false in Claude CLI --settings for text generation

• ClaudeTextGeneration.ts now unconditionally sets verbose:false in the settings object before merging optional flags, so --settings is always passed to the Claude CLI.
• Updates existing tests to expect verbose:false in the settings JSON and adds a new test verifying --settings {"verbose":false} is sent even when no other settings are specified.
• Adds a test asserting that stream-event CLI output fails with a TextGenerationError containing 'unexpected output format'.
• Behavioral Change: all Claude CLI invocations from text generation now include --settings with at least {"verbose":false}, whereas previously --settings could be omitted when no optional flags were set.

Approvability

Verdict: Approved at f581de8

Macroscope's review found this PR approvable — Small defensive bug fix that pins verbose: false to prevent user-level CLI configuration from breaking JSON output parsing. The 3-line production change is well-tested with new test cases covering both the fix and failure detection.
