fix(server): Claude --settings and prompt-file launch args expand ~#26649
Problem
The Claude provider's --settings <file> and --append-system-prompt-file <file> launch arguments did not expand ~, although the Binary path field of the same provider already does. T3 reads both files itself, so --settings ~/.claude/settings.json was resolved as <project>/~/.claude/settings.json, and the first message in any project failed with "Claude could not read the --settings launch argument at /path/to/project/~/.claude/settings.json as a JSON object."
Reproduced on main 9e09926d97 with the reporter's steps: dev server on a fresh database, Settings → Providers → Claude → Launch arguments, a project outside the home directory, a new Claude thread.
Change
readClaudeLaunchArgSettings and readClaudeAppendSystemPromptFile in ClaudeAdapterV2.ts now pass the value through expandHomePath(value, HostProcess.HomeDirectory) before resolving it against the cwd. That is the same helper and home directory binaryPath already uses. Relative paths still resolve against the project directory, and absolute paths and inline --settings JSON are unchanged.
Scope and approval
Fixes pingdotgg/t3code#26631
Triaged via the automated issue flow.
Verification
- New regression test in
apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts, one parametrised case per flag:reads --settings ~/.claude/settings.json from the home directoryandreads --append-system-prompt-file ~/.claude/settings.json from the home directory. On main both fail with the…/<cwd>/~/.claude/settings.jsonerror. With the fix, the whole file passes (250/250), including the existing relative-path, inline-JSON and error-message cases. vp run check:changedpasses.- Runtime check in the web app on a fresh dev database (Linux, Claude CLI 2.1.303, Haiku 5.5), each run in a new thread. Full runtime-transcript.md.
| Launch arguments | Before (main 9e09926d97) | After (fix 343cb3b604) |
|---|---|---|
--settings ~/.claude/settings.json | 01-settings-tilde-main.png | 04-settings-tilde-fix.png |
--append-system-prompt-file ~/.claude/settings.json | 02-append-prompt-tilde-main.png | 05-append-prompt-tilde-fix.png |
Control on main: the absolute path --settings /home/ubuntu/.claude/settings.json already worked (capture).
This is a server-only fix with no UI change, so the proof is the regression test plus the runtime run above.
Not checked: macOS desktop (the reporter's platform). The change is platform-independent path handling, and expandHomePath also accepts ~\ on Windows.
Model and harness: Claude Opus 5.5 (lead, red test, implementation) and GPT-6.1-Sol (review) in T3 Code.

Approvability
Verdict: Approved at 52a7b85
Macroscope's review found this PR approvable — Claude’s explicitly configured settings and prompt-file paths now expand ~ to the server’s home directory. Existing relative-path behavior and validation remain unchanged, with no product-default or permission changes.

Describe both launch-argument paths relative to the configured project cwd.
The normal adapter passes turnInput.runtimePolicy.cwd to both readers. The append-file comment says “process cwd,” and the settings comment only says “cwd.” Both descriptions should identify the configured project cwd. Otherwise, users can place a relative file in the process cwd and receive a file-read error because the adapter looks in the project cwd.
Suggested fix
- diff
1 - * the file relative to the process cwd, expanding a leading ~. 2 + * the file relative to the configured project cwd, or the process cwd when no project cwd is configured, expanding a leading ~. 3 ... 4 - * JSON, anything else is a file path relative to the cwd, expanding a leading ~. 5 + * JSON, anything else is a file path relative to the configured project cwd, or the process cwd when no project cwd is configured, expanding a leading ~. This documentation-only change is the complete correction. No runtime change is required.

Create a valid synthetic ~/.claude/settings.json and a project outside the server home. Start separate real Claude threads with --settings ~/.claude/settings.json and --append-system-prompt-file ~/.claude/settings.json; repeat both using absolute paths as controls. Environment: Linux, real T3 server/CLI, fresh isolated databases.

AI-assisted; verified with the tests and tools listed above.
Not shown:
- Settings UI navigation was not exercised; provider configuration was written before startup, and turns ran through the real server/CLI.
- Settings merge precedence and appended prompt contents were not separately inspected; the captures prove file-reading failures disappear and real turns complete.
