Summary

Closes #2480. CLI runtimes own reasoning depth — the thinkingLevel input pipeline has no runtime effect. This PR removes the remaining surface after prior PRs (#2463, #2464, #2465, #2466, #2467, #2471, #2475, #2476) eliminated most of it.

Net: 52 files changed, 185 insertions(+), 502 deletions(−). Deletes src/auto-reply/thinking.shared.ts entirely.

Removed (input pipeline — had no runtime effect)

• Orphan helper file: src/auto-reply/thinking.shared.ts (no importers)
• Dead helpers in thinking.ts: ThinkingCatalogEntry, isBinaryThinkingProvider, listThinkingLevels, shadow normalizeProviderId
• Config surface: subagents.thinking (agent-defaults + per-agent entries), hooks.mappings[].thinking, hooks.gmail.thinking — types, zod schemas, help, labels, quality test; regenerated schema.base.generated.ts
• CLI: --thinking flag from cron add/edit and agent command + help-text examples; [--thinking <level>] from /subagents spawn usage line
• Cron: thinking field from CronPayload, cron/normalize.ts, cron/normalize.test.ts, cron/service/jobs.ts (mergeCronPayload, buildPayloadFromPatch), cron/store-migration.ts, cron-cli tests
• Gateway: thinking from agent.send params, HookAgentPayload, HookAction, HookMappingResolved, server-http hook dispatch, server/hooks agentTurn payload, server-node-events voice + agent.request deep link
• Agent/subagent: thinking / thinkingOnce from AgentCommandOpts, agent-via-gateway payload, subagent-spawn (_thinkingOverrideRaw, thinkingOverride), sessions_spawn tool schema, cron-tool agentTurn payload doc + flat-params JOB_KEYS
• Protocol schemas: thinking from agent.ts, cron.ts, logs-chat.ts, sessions.ts
• ACP translator: thinking: readString(params._meta, [\"thinking\"]) removed from chat.send path; unused readString import removed
• Dead mocks: normalizeThinkLevel, supportsXHighThinking in run.test-harness.ts
• Dead param: resolvedThinkLevel?: unknown in buildStatusReply
• Docs: 9 files no longer teach --thinking / thinkingDefault (agent CLI, cron, TUI, subagents, platforms, gateway config-reference)

Added

• LEGACY_CONFIG_RULES entries for agents.defaults.thinkingDefault and agents.defaults.subagents.thinking
• strip-thinking-level-fields migration in LEGACY_CONFIG_MIGRATIONS — strips thinkingDefault, agents.defaults.subagents.thinking, agents.list[].subagents.thinking, hooks.mappings[].thinking, and hooks.gmail.thinking so existing configs still load cleanly (.strict() zod schemas would otherwise reject unknown keys)
• 3 new migration tests in src/config/config-misc.test.ts

Kept (intentional — different concepts)

• Output-event rendering: type === \"thinking\" content-block processing in middleware/runtimes/*.ts, gateway/server-methods/chat.ts transcript truncation, gateway/server/hooks.ts, sessions-history-tool.ts, acp/translator.ts output block rendering, tui/tui-formatters.ts, auto-reply/reply/export-html/template.{js,css}
• Telegram/Discord status-reaction emoji: thinking as lifecycle state (queued → thinking → tool → done) — distinct from thinking level
• Typing mode enum \"thinking\" state — UX indicator
• reasoningLevel: channel-bound middleware concern (Telegram draft streaming) — unchanged

CLI flag behavior after PR

remoteclaw cron add --thinking high now errors with error: unknown option '--thinking' (commander default). Same for cron edit, agent, and /subagents spawn --thinking.

Validation

• pnpm tsgo: clean
• pnpm lint: 0 warnings, 0 errors
• pnpm format:check: all files correctly formatted
• pnpm test: 7011 passed, 3 pre-existing skips (no new skips); includes 3 new migration tests for the strip-thinking-level-fields migration
• rg "thinkingLevel|thinkingDefault|ThinkLevel" src/: only migration/rule message text + two historical comments in acp/translator.ts referencing prior gut(session): drop SessionEntry.thinkingLevel field + gateway schema (#2336 Area 3) #2464 removal (intentional)
• rg "\.thinking\b|params\.thinking" src/: only output-event rendering, emoji lifecycle state, and migration strip code — all intentional
• rg "reasoningLevel" src/: 36 live hits across 22 files (intentional — separate concept, kept)

Test plan

• pnpm build (canvas bundle + build pipeline)
• pnpm test (7011 passed, 3 pre-existing skips)
• pnpm check (format + typecheck + lint)
• Manually verified existing configs with thinkingDefault or subagents.thinking trigger migration warning and auto-strip via new tests
• CI green on PR
