When a Claude thread runs a native Agent subagent, the subagent's chat lists its tool calls but never its thinking, during the run or after it. Claude Code (2.1.304 here, 2.1.312 in the report) no longer forwards a subagent's thinking over the Agent SDK stream: frames with a parent_tool_use_id carry only tool_use blocks. The thinking is written only to the subagent transcript, <claude config>/projects/<project>/<session>/subagents/agent-<task_id>.jsonl.
Reproduced on main (dd14848153) with the real server. A Claude Opus thread is asked to run one foreground subagent that reads three files and thinks between reads. The child thread gets user_message, command_execution ×3, assistant_message and no reasoning, while the subagent's transcript holds 3 thinking blocks. The same holds with Sonnet and with an Explore subagent.
The adapter now reads a native subagent's thinking from its transcript, using the contained, cursor-based reader that Workflow members already use.
projects/*/<session>.jsonl), not rebuilt from the cwd, so symlinked and long paths work. It is cached per session, along with a miss.uuid (the SDK frame and its transcript line share it). It re-reads every 25 ms, for at most 500 ms, while Claude Code flushes, about every 100 ms. Lines past the frame stay buffered for later frames.completed subagent waits the same way for its turn-end line, so its final thinking lands before the reply. A cancelled, stopped or failed subagent, or one whose query is closing, reads once and does not wait.closing deferred, set wherever the live query closes, ends any wait at once. A subagent whose transcript never appears holds only its first frame.uuid. Re-reading after a restart re-emits the same item ids, which keep their positions.Fixes pingdotgg/t3code#27116

Closing as a duplicate of #27211, which fixes the same bug (Claude subagent child threads showing no thinking, #27116 / #27178) by turning on the Agent SDK's forwardSubagentText option. Its probe shows Claude Code 2.1.304 and the reporter's 2.1.312 forward subagent thinking with that option on, so the fix stays a one-line query option instead of reading subagent transcripts from disk and holding frames. Thanks for the careful reproduction and the frame-ordering analysis here: the runtime transcript and the ordering tests were useful in comparing the two.
ClaudeAdapterV2 now reads native subagent transcripts to recover thinking omitted from SDK frames. It orders transcript thinking with SDK items, avoids duplicate thinking, and bounds transcript polling during query closure.

Explanation
The description includes complete Problem, Change, Scope and approval, and Verification sections. It explains the bug, implementation, linked issue, focused tests, runtime validation, and unverified environments.
Explanation
The only directly linked issue, #27116, is marked closed and completed. Its state text says it is historical context only and not a requirement for this pull request. No active directly linked target remains, so no linked-issue coding requirements apply. The pull request still addresses the reported behavior: it reads native subagent thinking from the transcript in ClaudeAdapterV2.ts. That work does not create a requirement.
Explanation
Based on the whole-PR summary and description, the changes stay within the native Claude subagent thinking path. In ClaudeAdapterV2.ts, the changes locate the transcript by session id, read it with a cursor, match lines to SDK frames by uuid, add ordering and settle waits, add a closing deferred, suppress duplicate thinking IDs, and retain transcript state across lifecycle updates. Closing helper use in query replacement, interruption, session close, and native-thread close supplies the closing signal that ends waits. In ClaudeAdapterV2.test.ts, the new tests cover these behaviors. The wake harness change that sets CLAUDE_CONFIG_DIR to a nonexistent default isolates transcript lookups and supports those tests. No change in the summary falls outside native subagent thinking. The source diff was not read in full; this verdict relies on the summary, which establishes the scope.

| 6 | L292: `CLAUDE_CODE_DISABLE_OFFICIAL_MARKETPLACE_AUTOINSTALL` | Set to `1` to disable automatic registration of the official plugin marketplace. Claude Code reads the variable when it is about to register the marketplace, usually during a machine’s first interactive launch. If the variable is set at that point, Claude Code skips the registration permanently. Unsetting the variable later doesn’t undo the skip. |
| 7 | L293: Run `claude plugin marketplace add anthropics/claude-plugins-official` to register the marketplace at any time |
| 8 | L294: `CLAUDE_CODE_DISABLE_PERMISSION_PROMPT_NOTIFY_HOOKS` | Set to `1` to stop Claude Code from running your 【149†`Notification` hooks for unanswered permission requests】 in sessions where Claude Code sends them to the Agent SDK’s `canUseTool` callback, which is how Claude Desktop and the VS Code extension host Claude Code. Has no effect in terminal sessions. Requires Claude Code v2.1.233 or later |
| 9 | L295: `CLAUDE_CODE_DISABLE_POLICY_SKILLS` | Set to `1` to skip loading skills from the system-wide managed skills directory. Useful for container or CI sessions that should not load operator-provisioned skills |
| 10 | L296: `CLAUDE_CODE_DISABLE_POWERSHELL_CMD_RM_DENY` | Set to `1` to turn off the 【150†PowerShell tool】 check that denies the `cmd` built-ins `rd`, `rmdir`, `del`, and `erase` on a 【151†system path】, such as a drive root or your home directory. Claude Code ignores this variable in a settings file’s `env` block. Requires Claude Code v2.1.283 or later |
| 11 | L297: `CLAUDE_CODE_DISABLE_REFUSAL_FALLBACK` | Set to `1` to turn off the 【38†automatic model switch when a safety classifier flags a request】, the behavior the 【152†`switchModelsOnFlag`】 setting controls |
| 12 | L298: `CLAUDE_CODE_DISABLE_STRUCTURED_OUTPUTS` | Set to `1` to stop Claude Code from sending the structured-output `output_config.format` field and the `anthropic-beta` value that pairs with it, for an 【153†LLM gateway】 whose upstream rejects them. This leaves on the other pre-release capabilities that 【126†`CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS`】 turns off. Requires Claude Code v2.1.288 or later |
| 13 | L299: `CLAUDE_CODE_DISABLE_SUBSTITUTION_RM_PROMPT` | Set to `1` to turn off the 【154†critical-path】 check for a recursive `rm` whose target is entirely the output of a command substitution, such as `rm -rf "$(pwd)"`. The other critical-path checks keep running. Set it in the environment that launches Claude Code, since Claude Code ignores a copy delivered through a settings `env` block. Requires Claude Code v2.1.281 or later |
| 14 | L300: `CLAUDE_CODE_DISABLE_TERMINAL_TITLE` | Set to `1` to disable automatic terminal title updates based on conversation context. This also skips the background small/fast-model request that 【155†generates a session title】, and turns off 【156†status reports to your terminal】 |
| 15 | L301: `CLAUDE_CODE_DISABLE_THINKING` | Set to `1` to omit the `thinking` parameter from API requests entirely. This is a compatibility option for proxies and gateways that reject the parameter. On models that think by default, omitting the parameter means the model may still think. To explicitly disable 【157†extended thinking†platform.claude.com】 on the Anthropic API, use `MAX_THINKING_TOKENS=0` instead. |
| 16 | L302: Neither variable turns thinking off on Opus 5.5, Sonnet 5.5, Haiku 5.5, or the Fable models, which can’t have thinking turned off. On 【158†third-party providers】, `MAX_THINKING_TOKENS=0` likewise omits the parameter, so the two variables behave the same there |
| 17 | L303: `CLAUDE_CODE_DISABLE_ULTRAREVIEW_TRUST_CHECK` | Set to `1` so that 【159†`claude ultrareview`】 doesn’t exit with `Error: Workspace not trusted` in a folder you haven’t trusted when it can’t ask you to trust it, such as in CI. Set it in the environment that launches Claude Code, not a settings `env` block, and only where every such run starts in a folder you trust. Runs that can ask still ask. Requires Claude Code v2.1.309 or later |

A running session applies new and changed values to its environment when you save the file, but a feature that reads its variables once at startup, such as 【13†OpenTelemetry monitoring】, keeps its startup values until you relaunch. |
| 124 | L100: Removing a variable from the file doesn’t unset it in a running session; the removal takes effect the next time you launch `claude`. |
| 125 | L101: ~/.claude/settings.json |
| 126 | L102: |
| 127 | L103: `{ |
| 128 | L104: "env": { |
| 129 | L105: "API_TIMEOUT_MS": "1200000", |
| 130 | L106: "BASH_DEFAULT_TIMEOUT_MS": "300000" |
| 131 | L107: } |
| 132 | L108: } |
| 133 | L109: ` |
| 134 | L110: |
| 135 | L111: Claude Code copies these values into its environment as written. No shell processes them, so shorthand such as `~` or `$HOME` stays as typed. For a variable that takes a path, such as `CLAUDE_CONFIG_DIR`, write the absolute path: `"CLAUDE_CONFIG_DIR": "/home/you/.claude-work"`. The file you choose controls who the variables apply to: |
| 136 | L112: File | Applies to |
| 137 | L113: --- | --- |
| 138 | L114: `~/.claude/settings.json` | You, in every project |
| 139 | L115: `.claude/settings.json` | Everyone working in the project, checked into source control |
| 140 | L116: `.claude/settings.local.json` | You, in this project only, gitignored when Claude Code saves a setting to it; add it to your gitignore if you create it by hand |
| 141 | L117: Managed settings | Everyone in your organization, deployed by an admin |
| 142 | L118: See 【14†Settings files】 for where each file lives and 【15†Settings precedence】 for how they combine when more than one sets the same variable. |
| 143 | L119: ## |
| 144 | L120: |
| 145 | L121: 【8†】 |
| 146 | L122: |
| 147 | L123: Precedence |
| 148 | L124: Some behaviors have both an environment variable and a dedicated settings key, and which one Claude Code reads first differs per key. For `ANTHROPIC_MODEL` and `CLAUDE_CODE_AUTO_CONNECT_IDE`, Claude Code reads the variable first and uses the `model` or `autoConnectIde` setting only when the variable is unset. For the pair you’re setting, check the variable’s row below and the key’s entry on the 【16†settings reference】. |
| 149 | L125: When the same variable is set in both your shell and a settings file `env` block, the settings file value applies in most sessions. Claude Code writes each `env` entry into the process environment, replacing the value inherited from the shell. 【17†How `env` values interact with your shell】 covers the sessions that keep the inherited value instead, and the 【18†`env` setting】 says when it applies them. A few variables are special-cased; the 【19†`env` setting】 lists the exceptions. |
| 150 | L126: In a settings file you can set a variable but you can’t remove one. To override a variable you can’t unset, such as a stale `CLAUDE_CODE_USE_VERTEX` exported by a shell profile you don’t control, set it to an empty string in the `env` block: `"CLAUDE_CODE_USE_VERTEX": ""`. Claude Code treats the empty value as unset for provider selection. Subprocesses still inherit the empty value. |
| 151 | L127: Between settings files, `env` values follow 【15†settings precedence】, so a managed settings entry overrides the same variable in user or project settings. Project and local settings can’t set some variables, such as `CLAUDE_CONFIG_DIR` and the OpenTelemetry exporter variables. 【20†Variables Claude Code ignores in `env`】 lists them, along with the OpenTelemetry off values that still apply. |
| 152 | L128: How an environment variable interacts with CLI flags and in-session commands varies per feature: `--model` and `/model` override `ANTHROPIC_MODEL`, while `CLAUDE_CODE_EFFORT_LEVEL` overrides `--effort` and `/effort`. When a variable interacts with another configuration source, its row in the 【9†Variables】 list states the precedence or links to the page that documents it. Claude Code reads shell environment variables at startup, so changes to them take effect the next time you launch `claude`. |
| 153 | L129: Variables set under the `env` key in settings files are reapplied to a running session when the file changes, with the startup-only exception described in 【21†Set variables in settings files】. |
| 154 | L130: ## |

| 156 | L132: 【9†】 |

| 158 | L134: Variables |
| 159 | L135: |
| 160 | L136: Numeric variables such as timeouts, token budgets, and retry counts accept scientific notation and digit-separator spellings in addition to plain digits, except where a variable’s row notes it takes plain digits only. For example, Claude Code reads `2e3` as 2000 and `64_000` as 64000. Before v2.1.211, these spellings could silently set a much smaller value, such as `1e6` setting a timeout to 1. |
| 161 | L137: For variables that turn a behavior on or off, set `1`, `true`, `yes`, or `on` to turn it on and `0`, `false`, `no`, or `off` to turn it off, in any casing.Some variables read only whether you set them at all, so any non-empty value including `0` turns the behavior on, and you turn the behavior off by unsetting the variable or setting it to an empty value. These variables work that way: |
| 162 | L138: * `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` |
| 163 | L139: * `DISABLE_TELEMETRY` |
| 164 | L140: * `DISABLE_ERROR_REPORTING` |
| 165 | L141: * `CLAUDE_CODE_TMUX_TRUECOLOR` |
| 166 | L142: * `IS_DEMO` |
| 167 | L143: One other variable has its own rule: `FORCE_HYPERLINK` reads a number, so only `0` turns it off. Each variable’s row also states its own rule. |
| 168 | L144: Variable | Purpose |
| 169 | L145: --- | --- |
| 170 | L146: `ANTHROPIC_API_KEY` | API key sent as `X-Api-Key` header. When set, this key is used instead of your Claude Pro, Max, Team, or Enterprise subscription even if you are logged in. In non-interactive mode (`-p`), the key is always used when present. In interactive mode, you are prompted to approve the key once before it overrides your subscription. To use your subscription instead, run `unset ANTHROPIC_API_KEY` |
| 171 | L147: `ANTHROPIC_AUTH_TOKEN` | Custom value for the `Authorization` header (the value you set here will be prefixed with `Bearer `) |
| 172 | L148: `ANTHROPIC_AWS_API_KEY` | Workspace API key for 【22†Claude Platform on AWS】, generated in the AWS Console. Sent as `x-api-key` and takes precedence over AWS SigV4 |
| 173 | L149: `ANTHROPIC_AWS_BASE_URL` | Override the 【22†Claude Platform on AWS】 endpoint URL. Use for custom regions or when routing through an 【23†LLM gateway】. Defaults to `https://aws-external-anthropic.{region}.api.aws`. Claude Code resolves the region with the 【24†same precedence as on Amazon Bedrock】 |
| 174 | L150: `ANTHROPIC_AWS_WORKSPACE_ID` | Required for 【22†Claude Platform on AWS】. Sent on every request as the `anthropic-workspace-id` header |
| 175 | L151: `ANTHROPIC_BASE_URL` | Override the API endpoint to route requests through a proxy or gateway. For what happens when that gateway rejects MCP tool search, see 【25†Tool search through an LLM gateway…[truncated]</excerpt> |

| 493 | EDIT (corrected): the test below verifies only the spawned agent path. The extension host still ignores `CLAUDE_CONFIG_DIR` on Windows (session list/switch, `settings.json`, MCP/plugin persistence all default to `~/.claude`), so this is not macOS-only or fixed — the host-side half of this issue still reproduces. See my follow-up below and @pasrom's root-cause analysis. Original kept for context. |

| 497 | Windows 11: works via the `claudeCode.environmentVariables` setting (ext 2.1.178) |
| 498 | |
| 499 | On Win 11 (extension 2.1.178, CLI 2.1.177) the `claudeCode.environmentVariables` setting does point the spawned Claude session at a non-default `CLAUDE_CONFIG_DIR`: |
| 500 | |
| 501 | "claudeCode.environmentVariables": [{ "name": "CLAUDE_CONFIG_DIR", "value": "C:\\Users\\<me>\\.claude-alt" }] |
| 502 | |
| 503 | To rule out a leaked shell variable, I opened the repo in a throwaway instance (`code --new-window --user-data-dir <temp> <repo>`) with no `CLAUDE_CONFIG_DIR` in the environment and a fresh profile; `/status` then came up under the account in the custom dir, not `~/.claude`. The setting was the only possible source. |
| 504 | |
| 505 | Since the issue is labeled `platform:macos` and the report was on 2.1.63, this suggests the bug is macOS-specific and/or was (partly) fixed by 2.1.178 — might be worth a maintainer scoping. (I only verified the setting path, not the shell-export path.) |

| 517 | @kdsrc this only partially works. I am also on Windows 11, though using WSL. |
| 518 | |
| 519 | * Switching between sessions does not work, it will show up empty when switching to an older session. |
| 520 | * Plugins and MCPs will not survive the VSCode session, I would need to reinstall every time with a new VScode session. |

| 543 | When asked to edit Claude Code configuration, Claude Code operates on `~/.claude/settings.json` even when `CLAUDE_CONFIG_DIR` is set to a different directory. The rest of the CLI honors `CLAUDE_CONFIG_DIR` correctly, so the config it edits is not the config it actually reads. Edits land in a file that is never loaded. |
| 544 | |
| 545 | ## Steps to reproduce |
| 546 | |
| 547 | 1. Set `CLAUDE_CONFIG_DIR` to an XDG-style path, for example `export CLAUDE_CONFIG_DIR="$HOME/.config/claude"`. Real settings live at `~/.config/claude/settings.json` and `~/.claude/settings.json` does not exist. |
| 548 | 2. Start Claude Code and confirm the env var is set. |
| 549 | 3. Ask it to change a setting, add a permission, or set an env var (this routes through the update-config skill). |
| 550 | |
| 551 | ## Expected behavior |
| 552 | |
| 553 | Reads and writes `settings.json` from `$CLAUDE_CONFIG_DIR`. |
| 554 | |
| 555 | ## Actual behavior |
| 556 | |
| 557 | Reads and writes `~/.claude/settings.json`, ignoring `CLAUDE_CONFIG_DIR`. On a machine where that file doesn't exist, it silently creates a new one that Claude Code never loads, so the change appears to succeed but has no effect. |
| 558 | |
| 559 | This is the same root cause as #16899 (statusline-setup agent, closed as stale) but broader. The path resolution used when editing config should honor `CLAUDE_CONFIG_DIR` everywhere, not just in the main read path. |
| 560 | |
| 561 | ## Environment |
| 562 | |
| 563 | * macOS (Darwin 25.5.0) |
| 564 | * `CLAUDE_CONFIG_DIR=~/.config/claude` |

| 576 | If you have a legitimate default `~/.claude` configuration dir, and then another one (or even several) for other purposes (multi-tenant setup) to which you point with `CLAUDE_CONFIG_DIR` (e.g. using `direnv`), then it's even worse: |
| 577 | |
| 578 | In addition to reading and reasoning from the wrong setup - the wrong file already contained the exact binding I'd asked for, so its contents get reported back as the current state - it does not just create a stale `~/.claude` tree when writing changes, but actually silently modifies another account's live configuration. |

Trim CLAUDE_CONFIG_DIR before resolving it.
When config.homePath is empty, makeClaudeEnvironment preserves the inherited value. The current check then converts an empty value to session.cwd and a whitespace-only value to a whitespace-named child of session.cwd. Native and workflow transcript readers use that path instead of their default Claude configuration directory.

| 2 | - adapterOptions.environment.CLAUDE_CONFIG_DIR === undefined |
| 3 | - ? undefined |
| 4 | - : path.resolve(session.cwd, adapterOptions.environment.CLAUDE_CONFIG_DIR); |
