Read-only health diagnostics for LingTai agents and bots. Use when an agent appears offline or unreachable, when a machine migration may have left stale MCP/addon command paths, when heartbeat/status/process/notification/log surfaces disagree, or before deciding whether to mail, refresh, CPR, or edit persistent configuration. Includes a bundled doctor.py script for layered local checks without exposing secrets.
Second-layer router for LingTai's progressive-disclosure operating manuals. Read this when resident substrate/procedures are too compact and you need the right lower reference. Route here for the expanded substrate/runtime model, lifecycle and `system` tool actions, the init.json composition and preset runtime model route, action/procedure discipline and skill routing, tool-result summarization, SQLite/`log.sqlite` trace inspection and trajectory mining, runtime/kernel update checks and nudges, environment variables, goal notifications, molt/memory questions, MCP/addon ownership, collaboration topology, and resident prompt design. The nested catalog below names each reference and its exact trigger.
Mandatory repository-local development guide for LingTai's Python kernel and runtime. Use this before changing code, architecture documents, tests, packaging, capabilities, adapters, or developer documentation in lingtai-kernel. Routes each task through the exact baseline, the distributed ANATOMY/CONTRACT systems, focused validation, and pull-request safety gates.
Operational guide for LingTai's built-in file tools: read, write, edit, glob, and grep. Use when working with local text files, deciding whether to use file tools versus bash, handling large files, avoiding binary/image misuse, or reading non-UTF-8 text via explicit bash/Python/iconv instead of complicating the core read tool. Covers UTF-8 policy, safe write/edit discipline, search workflows, and examples for GBK/Shift-JIS/Latin-1 conversion.
Router for LingTai's distributed code navigation system. Use this before navigating, creating, or maintaining kernel ANATOMY.md files. The normative anatomy-of-anatomy now lives at the repository-root ANATOMY.md; this skill explains how an agent enters and descends that graph, how it pairs with the distributed CONTRACT.md interface-definition graph, and what to do when code and navigation disagree.
Thin routing manual for NoKV-controlled workbenches. Use when an agent is asked to persist task inputs, scripts, outputs, logs, provenance, or run manifests through the `workbench_*` MCP tools instead of ordinary local file writes. Covers MCP registration, directory layout, append and edit discipline, conditional reads, cross-workbench queries, commit discipline, and leased checkpoint snapshots with naming, renewal, discovery, and point-in-time history reads.

| maintenance | Keep this catalogue complete for every LINGTAI_* variable read by production source or intentionally exposed test/daemon composition. For each new read, add name, purpose, default, accepted values, scope, read point, reload/restart behavior, invalid-value behavior, implementation anchor, and security note. Keep the router/progressive-disclosure links reciprocal; do not paste this catalogue into resident substrate or procedures. |
This is the deep reference for environment configuration. Resident prompt layers
only explain the two global Nudge axes. Values are read by the component named in
the table; changing a variable does not imply that an already-running component
reloads it. Never put secrets directly in an environment value when a supported
*_env/env_file configuration path can be used.
| Variable | Purpose / default | Accepted values and scope | Read/reload and invalid behavior | Anchor / security |
|---|---|---|---|---|
LINGTAI_NUDGE_ENABLED | Global Nudge publication switch; default on. | on/off (also true/false/1/0), all Nudge kinds for one process/workdir. | Read at each Nudge operation/heartbeat; no restart. Invalid falls back to on and emits a bounded diagnostic. | src/lingtai/kernel/nudge/__init__.py; disabling reminders is not an authorization boundary. |
LINGTAI_NUDGE_REPEAT_INTERVAL | Post-dismiss repeat interval for the same unresolved finding; default 24h. | Positive duration with s, m, h, or d, for example 30m, 24h, 2d; global. | Read at each Nudge operation; no restart. Invalid/zero/negative falls back to 24h and emits a bounded diagnostic. | src/lingtai/kernel/nudge/__init__.py; values affect reminder timing only, not resolution. |
LINGTAI_ACTIVE_STUCK_THRESHOLD_S | ACTIVE no-progress watchdog threshold; default 600 seconds. | Numeric seconds; kernel clamps values below 30 to 30. | Read when the watchdog evaluates a turn; next evaluation sees a changed value. Invalid falls back to 600. | src/lingtai/kernel/base_agent/lifecycle.py; tuning a watchdog can change availability, so operators should record it. |
LINGTAI_REFRESH_ENV_OVERWRITE | One refresh handoff lets edited env_file values replace inherited process values; default unset/off. | 1 enables the one-shot overwrite. | Read on boot/refresh setup; consumed/removed after use. Other values are treated as off. | src/lingtai/cli.py, src/lingtai/agent.py; do not log env-file contents. |
LINGTAI_RUNTIME_PYTHON | Interpreter used for runtime/self-check and host-tool routing; default unset (caller supplies sys.executable). | Executable path. | Read by consumers when invoked; restart/relaunch the consumer to change its process interpreter. Invalid/missing is a caller/configuration error, not a fallback to a remote runtime. | src/lingtai/cli.py and runtime checks; path is not a credential. |
LINGTAI_RUNTIME_VENV | Active runtime virtualenv hint; default unset. | Local directory path. | Read by host tools when invoked; change takes effect for a new tool/process. Missing is tolerated where the caller has another interpreter. | src/lingtai/cli.py; never infer package freshness from an unrelated shell Python. |
LINGTAI_AGENT_DIR | Workdir for an out-of-process MCP/client; default unset and normally injected by the launcher. | Existing local directory. | Read at MCP process start; restart the MCP process after changing. Invalid path fails the MCP/client operation. | src/lingtai/mcp_servers/_config.py; local path only, do not expose private workdir contents. |
LINGTAI_MCP_NAME | Name of the active MCP server; default unset. | Registered MCP name. | Read at MCP process start; restart after changing. Invalid/missing fails closed rather than selecting an arbitrary server. | src/lingtai/mcp_servers/_config.py; keeps one process bound to one server identity. |
LINGTAI_ENV_VERSION | Environment/config schema marker used by environment setup; default unset. | Version string. | Read by the setup caller; relaunch/setup after changing. Invalid is reported by the setup path. | src/lingtai/venv_resolve.py; do not treat a marker as proof of package trust. |
LINGTAI_TUI_DIR | TUI-managed project/config root hint; default unset. | Local directory. | Read by TUI-facing callers at invocation; restart caller after changing. Invalid path fails the caller's lookup. | src/lingtai/venv_resolve.py/TUI integration; path may reveal local layout. |
LINGTAI_ORIGINATOR | Non-secret origin label for launched work; default unset. | Short string. | Read at process construction; restart/relaunch to change. Invalid is treated as absent. | src/lingtai/kernel launch surfaces; do not use it for authorization. |
LINGTAI_FILE_IO_BACKEND | Selects file-I/O backend; default implementation backend. | Backend name recognized by the wrapper. | Read when file-I/O service is constructed; rebuild/restart service. Unknown value fails closed. | src/lingtai/services/file_io.py (where available); backend selection is not a sandbox. |
LINGTAI_FILE_IO_SIDECAR | File-I/O sidecar executable/path hint; default unset. | Local executable/path. | Read at service construction; restart service. Invalid/unavailable sidecar fails the selected path. | File-I/O service adapter; do not grant sidecar broader filesystem authority than intended. |
LINGTAI_SEARCH_SIDECAR | Search sidecar executable/path hint; default unset (pure-Python fallback where supported). | Local executable/path. | Read when search service is constructed; restart service. Invalid sidecar uses the documented fallback or fails the operation; it never downloads one. | Search service adapter; validate executable ownership before use. |
LINGTAI_SKIP_RUST_BUILD | Developer/package-build switch to skip the Rust search-sidecar build; default unset/off. | 1 enables skip in build/test setup. | Read by build setup at build invocation; rerun the build after changing. Invalid values are treated as off. | setup.py / wheel tests; do not ship a production wheel claiming a sidecar it did not build. |
LINGTAI_REQUIRE_RUST_BUILD | Developer/package-build switch requiring the Rust search-sidecar build; default unset/off. | 1 enables requirement in build/test setup. | Read by build setup at build invocation; rerun the build after changing. Invalid values fail the required-build path. | setup.py / wheel tests; build policy is not runtime authorization. |
LINGTAI_SOUL_FLOW_ENABLED | Enables optional soul-flow capability; default disabled unless the host enables it. | 1/0 (implementation also accepts the component's documented boolean forms). | Read when soul capability is bootstrapped; refresh/restart capability after changing. Invalid is treated as disabled. | src/lingtai/tools/soul; not a command-execution or approval switch. |
LINGTAI_TASK_CARD_MAX_TOOL_ROWS | Bounds rendered Telegram task-card tool rows; default component limit. | Positive integer. | Read by the Telegram manager when rendering a card; next render sees valid changes. Invalid falls back to the component default. | src/lingtai/mcp_servers/telegram; bounds output size, not message authority. |
LINGTAI_PROFILE_MIME | Optional MIME/profile hint for bundled skill/profile transport; default unset. | MIME string. | Read when the profile resource is loaded; reload resource after changing. Invalid is ignored/fails the resource lookup. | src/lingtai profile loader; never use it to bypass content validation. |
LINGTAI_SKILL_MIME | Optional MIME hint for skill transport; default unset. | MIME string. | Read at skill-resource load; reload resource after changing. Invalid is ignored/fails lookup. | src/lingtai skill loader; content still requires normal skill validation. |
LINGTAI_CLOUD_MAIL_CONFIG | Cloud-mail configuration path/name; default unset. | Local config reference. | Read when cloud-mail integration starts; restart integration after changing. Invalid config fails closed. | Cloud mail adapter; config may contain credentials, so keep file permissions private. |
LINGTAI_IMAP_CONFIG | IMAP MCP config path/name; default unset. | Local config reference. | Read when IMAP MCP starts; restart MCP after changing. Invalid config fails closed. | src/lingtai/mcp_servers/imap; do not print config or password. |
LINGTAI_FEISHU_CONFIG | Feishu MCP config path/name; default unset. | Local config reference. | Read when Feishu MCP starts; restart MCP after changing. Invalid config fails closed. | src/lingtai/mcp_servers/feishu; keep app secrets out of logs. |
LINGTAI_TELEGRAM_CONFIG | Telegram MCP config path/name; default unset. | Local config reference. | Read when Telegram MCP starts; restart MCP after changing. Invalid config fails closed. | src/lingtai/mcp_servers/telegram; protect bot tokens and chat routing. |
LINGTAI_WECHAT_CONFIG | WeChat MCP config path/name; default unset. | Local config reference. | Read when WeChat MCP starts; restart MCP after changing. Invalid config fails closed. | src/lingtai/mcp_servers/wechat; protect credentials and contact state. |
LINGTAI_WHATSAPP_CONFIG | WhatsApp MCP config path/name; default unset. | Local config reference. | Read when WhatsApp MCP starts; restart MCP after changing. Invalid config fails closed. | src/lingtai/mcp_servers/whatsapp; protect credentials and recipient state. |
These are adapter/provider controls. The kernel does not reinterpret them as Nudge policy. Defaults below mean “unset” unless the provider adapter documents a provider-specific default.
| Variable | Purpose / default | Accepted values and scope | Read/reload and invalid behavior | Anchor / security |
|---|---|---|---|---|
LINGTAI_CODEX_TRANSPORT | Legacy/diagnostic transport hint; normal runtime remains the adapter's default REST path. | Adapter-recognized diagnostic value; default unset. | Read by the provider adapter at session construction; restart session. Unsupported values do not silently switch to an unsafe transport. | src/lingtai/llm; do not put bearer tokens in transport hints. |
LINGTAI_CODEX_WS | Legacy WebSocket experiment/diagnostic hint; default unset/off. | Adapter-recognized value; normal production behavior is unchanged when set by itself. | Read at provider-session construction; restart session. Unsupported values are ignored/rejected by the adapter. | src/lingtai/llm; transport selection is not a trust boundary. |
LINGTAI_CODEX_WS_EPOCH_RESET_TURNS | Diagnostic WebSocket epoch reset count; default adapter default. | Positive integer. | Read at session construction; restart session. Invalid falls back to adapter default. | Codex adapter; avoid values that cause unexpected session churn. |
LINGTAI_CODEX_RESPONSES_TRACE | Enables bounded Responses-wire tracing for diagnostics; default off. | Adapter-recognized boolean. | Read at session construction; restart session. Invalid is treated as off. | Codex adapter; traces must remain redacted and local. |
LINGTAI_CODEX_RESPONSES_TRACE_PATH | Local destination for Responses-wire diagnostics; default unset/adapter default. | Local path. | Read at session construction; restart session. Invalid/unwritable path fails closed or disables tracing. | Codex adapter; trace files can contain sensitive prompts, so restrict permissions. |
LINGTAI_CLAUDE_MANAGED_ROOT | Claude managed installation root; default host-specific/ unset. | Local directory. | Read by Claude launcher at launch; relaunch after changing. Invalid path fails closed. | Claude adapter; never widen root based on untrusted model text. |
LINGTAI_CLAUDE_INTERACTIVE_FIFO | Claude interactive FIFO path; default unset. | Local FIFO/path. | Read at interactive launch; relaunch after changing. Invalid type/permissions fail closed. | Claude adapter; protect FIFO from other users/processes. |
The following variables are intentionally not user-facing product configuration. They are injected by daemon supervisors, fake backends, or focused tests. They are catalogued so an audit can distinguish a test hook from a runtime control. Do not set them in a production agent environment.
| Variable | Purpose / default | Accepted values and scope | Read/reload and invalid behavior | Anchor / security |
|---|---|---|---|---|
LINGTAI_DAEMON_CAPSULE_FD | Supervisor-provided capsule file descriptor; default unset. | Integer FD supplied by the supervisor. | Read once at daemon start; restart daemon. Invalid/missing fails the supervised path. | src/lingtai/kernel/daemon_supervisor; never accept an arbitrary inherited FD without supervisor validation. |
LINGTAI_DAEMON_CAPSULE_HANDLE | Windows capsule pipe HANDLE number; default unset. | Integer OS handle inherited via the spawn handle_list. | Read/consumed once by the Windows daemon entrypoints, which convert it to the FD wire above; restart daemon. Carries only the handle number, never capsule content. | src/lingtai/adapters/windows/daemon_supervisor.py; never accept an arbitrary inherited handle without supervisor validation. |
LINGTAI_DAEMON_COMPLETION_FILE | Daemon completion marker path; default unset. | Supervisor-owned local path. | Read once at daemon start; restart daemon. Invalid path fails completion reporting. | Daemon completion MCP/runner; keep path within the assigned run directory. |
LINGTAI_DAEMON_CREDENTIALS_RESTORED | Internal marker that credential restoration finished; default unset. | Supervisor boolean marker. | Read during daemon startup; restart daemon. Invalid/missing means credentials are not considered restored. | Daemon supervisor; never log restored credential contents. |
LINGTAI_DAEMON_DETACHED_SUPERVISOR | Internal detached-supervisor mode; default unset/off. | Supervisor boolean marker. | Read once at daemon startup; restart daemon. Invalid is treated as off/fails the detached path. | Daemon supervisor; does not authorize external side effects. |
LINGTAI_DAEMON_RUN_ID | Correlates one daemon run; default unset. | Opaque run identifier. | Read at daemon startup and event/token writes; restart daemon to change. Invalid/missing is a run-integrity error where required. | Daemon run directory; do not use as a secret or expose unrelated run IDs. |
LINGTAI_DAEMON_SUPERVISOR_TEST_FAKE_LLM | Test fake-LLM switch; default off. | Test-only boolean. | Read at test/supervisor construction; restart child. Invalid is off. | Test/supervisor code; never enable in production. |
LINGTAI_DAEMON_SUPERVISOR_TEST_FAKE_LLM_FINISH | Test fake-LLM finish mode; default unset. | Test scenario string. | Read at child construction; restart child. Invalid scenario fails the test. | Test/supervisor code; no production effect. |
LINGTAI_DAEMON_SUPERVISOR_TEST_FAKE_LLM_SCENARIO | Selects a fake-LLM test scenario; default unset. | Registered test scenario. | Read at child construction; restart child. Unknown scenario fails closed. | Test/supervisor code; never use to bypass real provider checks. |
LINGTAI_DAEMON_SUPERVISOR_TEST_FAKE_LLM_SLEEP | Fake-LLM test delay; default zero/unset. | Non-negative numeric seconds. | Read at fake backend construction; restart child. Invalid falls back to zero or fails the test. | Test/supervisor code; not a production timeout control. |
LINGTAI_FAKE_CLI_REPORT | Test fake CLI report path/content selector; default unset. | Test-only path/selector. | Read by fake CLI at invocation; rerun test after changing. Invalid fails the test. | tests/_fake_*; do not set in production. |
LINGTAI_TEST_CONFIG | Test fixture configuration selector; default unset. | Test-only string/path. | Read when fixture is built; rerun test after changing. Invalid fails fixture setup. | tests/; no production behavior. |
LINGTAI_TEST_FAKE_CLAUDE_SIGNAL_RECORD | Test fake Claude signal record path; default unset. | Test-only local path. | Read by fake launcher at invocation; rerun test after changing. Invalid fails the test. | tests/; keep artifacts in the test temp directory. |
