fix(claude): isolate capability probe settings - #8908
Conversation
📝 WalkthroughWalkthroughClaude capability probes now resolve each instance’s config directory, run from a neutral temporary directory, and pass the workspace separately to the Claude Agent SDK. Cache keys and tests use the resolved config directory. ChangesClaude probe isolation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Claude capability probes can still inherit settings from the shared temporary directory, potentially causing an isolated provider to use unintended configuration or credentials. Use a private probe directory before merging. Sequence Diagram(s)sequenceDiagram

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — The PR changes the periodic Claude capability probe's subprocess cwd, configuration environment, and cache identity, directly affecting the authentication profile and account metadata surfaced by provider health checks. Because this is an authentication-sensitive runtime change, human review is warranted. Not approved because:

Use a private probe directory.
Line 71 runs the CLI from the shared system temporary-directory root. If ${NodeOS.tmpdir()}/.claude/settings.json exists, Claude can load it as project settings and override the isolated provider configuration. This reintroduces the capability-probe isolation failure.
Create an owned, unique, existing temporary subdirectory for the probe cwd. Clean it up when the provider is disposed. Keep the workspace only in additionalDirectories.

Fixes #8818.
Claude capability probes inherited the server working directory. On desktop this can be the user home, letting
~/.claude/settings.jsonoverride a provider instance that has its ownCLAUDE_CONFIG_DIR.Use the configured instance root as the probe cwd and include that isolated location in the capability cache identity. Normal project skill discovery remains on the server project cwd.
Verification:
vp fmt --check, focused Claude home and capability-probe tests (6 passing), and server typecheck (existing suggestions only).Model and harness: GPT-5 Codex via Codex CLI.
Note
Medium Risk
Changes periodic health-check subprocess cwd/env and capability cache keys, which can alter reported auth/slash-command metadata until caches refresh; skill discovery path logic is consolidated but should match prior precedence.
Overview
Fixes capability probes picking up the wrong Claude settings when the server process cwd is the user home (or otherwise exposes
<cwd>/.claude/settings.json), which could override a provider instance’s intended config.Config resolution is centralized in
resolveClaudeConfigDirPath(providerhomePath→CLAUDE_CONFIG_DIR→HOME/USERPROFILE+.claude, with relative env paths resolved against the workspace cwd).ClaudeSkillsdrops its duplicate resolver and uses the shared helper.Capability probes now build context via
makeClaudeCapabilitiesProbeContext: subprocess cwd is a neutral temp directory, while the resolved config dir is injected asCLAUDE_CONFIG_DIR. The real workspace is still passed through asadditionalDirectories/workspaceCwdso project setting sources remain available without treating the workspace as the probe cwd.Cache identity for probes changes from
binary + home + cwdtobinary + resolved config directory, so instances that share config but differ by workspace cwd can share probe results; the key format also drops the trailing separator.Reviewed by Cursor Bugbot for commit 2afb666.

Note
Isolate Claude capability probe settings from workspace cwd
resolveClaudeConfigDirPathto centralize Claude config directory resolution, giving precedence to provider home override, thenCLAUDE_CONFIG_DIR, thenHOME/USERPROFILE/platform home. RelativeCLAUDE_CONFIG_DIRpaths are resolved against the workspace cwd.CLAUDE_CONFIG_DIRin the probe environment. The workspace cwd is forwarded as anadditionalDirectoriesentry so the probe can still access it.ClaudeSkillsto use the shared resolver, removing its private duplicate.makeClaudeCapabilitiesCacheKeyin ClaudeHome.ts now produces a different key format (binary + resolved config dir, no cwd or trailing separator); any persisted or cross-version cache consumers will see fresh cache misses.Macroscope summarized 2afb666.
