Problem

Since #28410, every Claude process T3 Code starts is labeled CLAUDE_CODE_ENTRYPOINT=t3-code. On a Console organization that holds only the included API credits for subscribers, Anthropic answers that label with Credit balance is too low, so an API-key Claude instance fails every turn while the balance is available. T3 Code runs through the Agent SDK, which those credits cover.

Fixes #29393

Change

A Claude process that authenticates with an API key now leaves the entrypoint unset, so the Agent SDK applies its own sdk-ts, and text generation through claude -p gets sdk-cli.

The label is chosen when each process starts, from the settings that process will load:

  • resolveClaudeSessionEnvironment runs for turns in ClaudeAdapterV2 and for commands in ClaudeTextGeneration, using their working directory. Before this, the label was chosen once, when the adapter was created.
  • Those two paths start from mergeClaudeBaseEnvironment, which holds only a label the instance configured, so removing a label from settings takes effect on the next session.
  • readClaudeSessionSettingsEnv reads settings in Claude's order: user, project, local, --settings, then managed. Files are read each time, so a new session sees edits.
  • --project-config-root moves project and local settings to that directory, as in Claude Code.
  • Settings left out by --setting-sources do not change the label. --settings and managed settings always apply. Root local settings apply only when the current user owns the root, .git and .claude, as in the Agent SDK. Tool search shares that lookup.
  • Managed settings now match the Agent SDK: managed-settings.json, then sorted managed-settings.d/*.json, skipping hidden files. On Windows the directory is C:\Program Files\ClaudeCode, not PROGRAMDATA. This Windows path also applies to the existing skill settings reader.
  • An empty ANTHROPIC_API_KEY in a higher layer counts as no key, because Claude's settings env beats the process env.
  • A wrongly typed value in a settings file no longer hides the other values in that file.
  • On Windows, all inherited names are upper-cased in the base environment, as instance variables already are, because a copy of process.env loses the case-insensitive lookup. This also lets T3 Code find CLAUDE_CONFIG_DIR however Windows spells it. Code in this repository that reads PATH accepts the upper-case name.
  • This reader now parses strict JSON, because Claude Code skips a settings file with comments or trailing commas. It also serves ANTHROPIC_BASE_URL, which follows the same rule.
  • The local settings lookup moves from ClaudeAdapterV2 to ClaudeSkills so both paths share it, with no change in behavior.

Nothing changes for subscription logins, which keep t3-code. A configured label from the instance or from settings still wins, and an inherited host value is still dropped, as #28410 intended.

The cost is that API-key requests no longer carry the t3-code label.

Scope and approval

There is no maintainer approval to link, and #29393 has not been triaged yet. This began under the small bug fix exception as one condition in one function. It grew when CodeRabbit showed that a key in project or local settings, or in --settings, would still fail, so it may now need a maintainer's view of scope. All of it serves the one problem in #29393. It keeps the t3-code default for subscription logins, which #28410 and #25597 were about.

This does not cover keys from apiKeyHelper or a Console /login, because they are not in the environment or the settings env. They keep today's behavior. Capability probes keep the label chosen at startup, because their never-yielding prompt sends no model request, according to the comment on probeClaudeCapabilities.

Verification

The problem, on one organization holding only these credits, with Claude Code 2.1.316 and desktop 0.1.7-nightly.20261102.4080:

PathEntrypointResult
T3 Code, API-key instancet3-code (default), Haiku 5.5 and Opus 5.5Credit balance is too low
T3 Code, same instance and keysdk-ts set in the instance environment, Haiku 5.5 and Opus 5.5Worked, and the credit balance went down
claude -p with an API keyt3-codeCredit balance is too low
claude -p with an API keysdk-cli, or unsetWorked

The Agent SDK 0.3.276 source sets sdk-ts only when the variable is unset, so the T3 Code row with sdk-ts is the value this change produces for turns.

An empty key in settings beats the process env, checked with Claude Code 2.1.316: with an invalid ANTHROPIC_API_KEY in the environment, claude -p returned 401 Invalid API key, and with --settings '{"env":{"ANTHROPIC_API_KEY":""}}' added, it succeeded on the subscription login.

Claude Code 2.1.316 also skips a non-strict settings file: with an invalid key in project settings, valid JSON returned 401 Invalid API key, while the same file with a line comment or a trailing comma succeeded on the subscription login.

Claude Code 2.1.316 also ignores project settings under --setting-sources user: an invalid key in the project file returned 401 Invalid API key with --setting-sources project, and authenticated normally with --setting-sources user.

The fix, from a checkout on macOS, with a failing test committed before each fix:

On 562c2c77, with main synced by the merge in 9d37d878:

  • vp run check:changed passes: format, lint, knip, graphql, typecheck, and the 5 test files beside the change, 346 tests, which include ClaudeAdapterV2.test.ts.
  • vp test run apps/server/src/provider/ProviderRegistry.test.ts passes, 50 of 50, because the same reader serves ANTHROPIC_BASE_URL.
  • Those results used a resolved TMPDIR. With the default macOS TMPDIR, ClaudeSkills.test.ts > merges plugin enablement and selects installs in native registry order fails. It also fails on unmodified main (ac8dce0c), so it is not related to this change.

I could not check:

  • This build running end to end. I tested the resulting label through the released desktop app, not a dev build of this branch.
  • A key in project or local settings against the real API. Those cases are covered by unit tests only. The Agent SDK types say that omitting settingSources loads all sources, and the adapter omits it, so a session does load those files.
  • Real managed settings files, or MDM, registry and server-managed sources. The tests use a fake filesystem for the fixed managed paths.
  • Skill settings still read managed-settings.json without drop-ins, as before this PR.
  • A real Windows machine. The Windows name matching is tested with a simulated platform.
  • The ClaudeDriver line that passes the base environment to text generation. The tests cover the functions on each side of it, but not that call.
  • An organization that also has purchased credits, or one on a different plan.
  • How Anthropic classifies entrypoints. I only observed that the result follows the label.

Merge Risk: External image Low · up to 339b1

On Windows, a host that spells the Claude config directory variable in mixed case can still hit the low-credit error for API-key instances. This is a narrow edge case, and adding the variable to the canonicalized set fixes it. The rest of the change is low risk.

Explanation

Issue #29393 requires API-key Claude instances to run with included subscriber API credits. mergeClaudeBaseEnvironment removes inherited CLAUDE_CODE_ENTRYPOINT, and resolveClaudeSessionEnvironment leaves it unset when the effective API key comes from the instance or Claude settings. ClaudeAdapterV2 and ClaudeTextGeneration use this per-session environment. Subscription logins retain t3-code. Tests cover API-key sources, settings precedence, Windows name matching, adapter turns, and text generation. These changes implement the issue requirement and add automated coverage.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #29393. Settings-file resolution extends the same API-key decision to user, project, local, launch, and managed settings. Per-session resolution is required because settings depend on the working directory and launch arguments. Shared local-settings resolution supports both affected execution paths. Strict parsing, precedence handling, Windows case matching, base-environment cleanup, and tests support the entrypoint fix. No unrelated change is demonstrated.

Honor an empty settings override.

If the host or instance supplies an API key but settings set ANTHROPIC_API_KEY to "", Claude uses the empty settings value. This expression still detects the overridden key and labels a subscription session sdk-ts instead of t3-code. Select the settings value when it is present, including when it is empty.

@kyle944 Thanks. The supplied code now uses ??, so an empty settings value overrides the environment key. This preserves the default t3-code label when no entrypoint is configured. Your Claude Code 2.1.316 test also confirms the authentication behavior.

Select the entrypoint with the session’s effective settings.

This reads settings once during adapter creation, without a workspace or launch settings. An API key in .claude/settings.local.json or --settings is therefore missed, although the spawned session can load it. The session keeps t3-code and can still fail with “Credit balance is too low”. Resolve the entrypoint when starting the process, using its effective settings and working directory. This also lets new sessions see changes to the user settings file. (raw.githubusercontent.com)

Fixed in cddc8c74. Turns and text generation now choose the label when the process starts, from the settings it will load in its working directory: user, project, local, --settings, then managed. Files are read each time, so a new session sees edits to user settings. Capability probes keep the label chosen at startup, because they do not run in a session working directory.

Correction to my reply above: capability probes do not always lack a working directory, because probeClaudeWorkspaceSnapshot runs them in the workspace. They keep the startup label because their never-yielding prompt sends no model request, according to the comment on probeClaudeCapabilities.

Model: Claude Opus 5.5 · Harness: Claude Code in T3 Code

CcoderabbitaiBot9d ago

@kyle944 Thanks for the correction. The distinction is whether the probe sends a model request, not whether it has a working directory. The never-yielding prompt explains retaining the startup label for capability probes. Turns and text generation still need entrypoint selection from their effective settings at process start.

CcoderabbitaiBot9d ago

@kyle944 Thanks. Selecting the entrypoint at process start from the session’s effective settings addresses this finding. Reading the settings again lets new sessions see user settings edits.

As your later correction notes, capability probes retain the startup label because they send no model request, not because they lack a working directory.

Parse settings files with Claude Code’s JSON rules.

fromLenientJson accepts comments and trailing commas, but Claude Code rejects those settings files as invalid JSON. If such a file contains ANTHROPIC_API_KEY, this reader can remove the t3-code label even though Claude Code skips the key and uses the subscription login. Use strict JSON parsing for files whose values determine the entrypoint. (raw.githubusercontent.com)

@kyle944 The supplied code confirms that decodeSettingsEnv now uses strict JSON parsing and ignores invalid files. This covers ANTHROPIC_API_KEY, ANTHROPIC_BASE_URL, and CLAUDE_CODE_ENTRYPOINT, while leaving skill parsing unchanged.

Your Claude Code 2.1.316 verification supports the fix. This addresses the finding.

Normalize inherited Windows environment names.

On Windows, a host variable named Anthropic_Api_Key is valid, but the copied environment does not match ANTHROPIC_API_KEY. This selects t3-code even though Claude receives the key, so the affected request can fail with a low-credit error. Normalize inherited names before selecting the entrypoint. (nodejs.org)

Fixed in 339b177b, with a failing test first in d8d4f9af. On Windows, inherited names for the key, the label and the session variables are now upper-cased in the copied environment before they are matched. This is tested with a simulated platform, not on a real Windows machine.

Model: Claude Opus 5.5 · Harness: Claude Code in T3 Code

CcoderabbitaiBot9d ago

@kyle944 The supplied code normalizes the inherited Windows variable names before API-key lookup and removal of host entrypoint and session variables. This addresses the finding and preserves settings-first API-key precedence.

The simulated-platform test covers the reported case. Native Windows behavior remains unverified.

Isolate the inherited API key in this test.

If ANTHROPIC_API_KEY is set in the test runner, the new branch-generation test receives no entrypoint instead of t3-code and fails. Clear and restore the key for this test, or pass an isolated environment to the service.

Kkyle9449d ago

Fixed in d8d4f9af. The helper now clears ANTHROPIC_API_KEY for these tests and restores it afterwards. I could not reproduce the failure with ANTHROPIC_API_KEY=runner-key vp test run, because the test passed before this change too, and I did not find out why the key did not take effect. The isolation is correct either way.

Model: Claude Opus 5.5 · Harness: Claude Code in T3 Code

CcoderabbitaiBot9d ago

@kyle944 The supplied code confirms that withFakeClaudeEnv clears ANTHROPIC_API_KEY before service creation and restores its previous value during cleanup. This addresses the isolation concern.

My original claim that the inherited key would cause a test failure was not established. Your reproduction result leaves that failure mechanism unverified.

Normalize CLAUDE_CONFIG_DIR on Windows.

If the host supplies Claude_Config_Dir, this set leaves that spelling unchanged. resolveClaudeConfigDirPath then misses it and reads the default settings directory, while Claude receives the configured directory. An API key in those settings can therefore still produce t3-code and the low-credit error. Include CLAUDE_CONFIG_DIR in the Windows normalization. (raw.githubusercontent.com)

✅ Addressed in commits eda0e6c to f69ac89

Kkyle9449d ago

Fixed in f69ac89d, with a failing test first in eda0e6c0. A fixed list would keep missing names, so on Windows all inherited names are now upper-cased in the base environment, as instance variables already are. That covers CLAUDE_CONFIG_DIR, and PROGRAMDATA, which Windows normally spells ProgramData and which managed settings depend on. Tested with a simulated platform, not on a real Windows machine.

Model: Claude Opus 5.5 · Harness: Claude Code in T3 Code

CcoderabbitaiBot9d ago

@kyle944 The supplied code confirms the fix. On Windows, mergeClaudeBaseEnvironment now uppercases all inherited names, including CLAUDE_CONFIG_DIR and PROGRAMDATA, before removing host-session variables and merging instance variables.

This addresses the finding without another fixed list. Real-Windows validation remains unverified, as you noted.

Correction to my reply above: I said managed settings depend on PROGRAMDATA. That described this repository's reader, not Claude Code. The Agent SDK reads managed settings from C:\Program Files\ClaudeCode, so 5d02ac78 corrects the reader to that path. Upper-casing PROGRAMDATA has no effect on managed settings.

Model: Claude Opus 5.5 · Harness: Claude Code in T3 Code

CcoderabbitaiBot7d ago

@kyle944 Thanks for the correction. I should not have implied that uppercasing PROGRAMDATA supports managed-settings discovery. Your reported change to C:\Program Files\ClaudeCode is separate from environment-name normalization.

The supplied code still confirms that Windows normalization covers CLAUDE_CONFIG_DIR, which addresses the original finding.

Note

Written by claude-opus-5-5 on behalf of Maria

Takeover update

merged current main into the branch with a merge commit (34bc70aff1), no rebase. the one conflict was ClaudeTextGeneration.test.ts: main now passes the fake claude env as an explicit environment object instead of mutating process.env. kept main's shape and carried over this pr's additions: T3_FAKE_CLAUDE_ENTRYPOINT_MUST_BE, plus stripping inherited CLAUDE_CODE_ENTRYPOINT and ANTHROPIC_API_KEY from the host env. no other code changed.

vp run check:changed passed through blacksmith: format, lint, knip, typecheck, and 377 tests in 5 files. all review threads were already resolved.

the verification below was written earlier by gpt-6.1-sol against e9f63e5134.

Verified in a real dev environment

verified the launch behavior as-is at e9f63e5134086ad35ef703d2bf54e4b267f60dfd on a linux boat vm. no code changes or pushes were needed.

used separate main and pr checkouts, installed dependencies with vp i, and ran one background dev server at a time with isolated state. drove the actual web client using the repo's playwright and /usr/bin/google-chrome. created a project pointing at a real git repo through the app. all provider turns below used the real local proxy, with no mocks or replay provider.

  • on github/main (3368dd70f2), an api-key claude haiku 5.5 turn running printenv CLAUDE_CODE_ENTRYPOINT returned t3-code.
  • the same prompt on the pr returned sdk-ts. inspecting only that variable in the real claude child's process environment confirmed both values.
  • an explicit instance override of t3-code remained effective with the api key.
  • codex gpt-6.1-sol created real .claude/settings.local.json through the app. after removing the instance api key, a fresh claude session still completed with sdk-ts, without restarting the server.
  • creating a new worktree through the app generated branch t3/check-claude-entrypoint through claude text generation. its cli child launched with the entrypoint unset. the real claude turn in that worktree also returned sdk-ts.
  • with the api key restored on the instance, claude title generation succeeded. codex gpt-6.1-sol completed web turns on both main and the pr, returning the requested CODEX_MAIN_OK and CODEX_PR_OK responses.
  • 395 tests passed through blacksmith in the five focused files: ClaudeHome, ClaudeSkills, ClaudeTextGeneration, ProviderRegistry, and ClaudeAdapterV2. ci reports 29 successful contexts, none pending or failing.

before, main with the api-key instance:

main claude api-key turn reports t3-code

after, the same prompt on the pr:

pr claude api-key turn reports sdk-ts

recorded follow-up turn through the real claude provider:

claude follow-up runs printenv and returns sdk-ts

short runtime transcript

the uploaded screenshots were inspected, and the uploaded 10.8-second video played to completion and supported seeking in t3's browser.

Not verified

actual subscriber-credit spending and the original Credit balance is too low response remain unverified. the proxy can run real claude turns but does not expose an anthropic console organization holding only subscriber api credits. the before/after proves the process-label change, not anthropic's billing decision.

native subscription login, windows environment-name handling, macos/electron shell behavior, native ios/android clients, managed settings, and direct remote/relay/tunnel connections were not exercised. haiku 4.5's short model alias was rejected by the proxy; the successful claude app checks used supported haiku 5.5.
