This renders them as terminal rows that always fit their width: headings, nested and task lists, quotes, GFM tables that wrap cells (records when far too narrow), fenced code with a gutter and language-aware highlighting from the person's syntax roles, and rules. Links become OSC 8 hyperlinks only for http(s) targets and always show where they go; refused targets stay visible as text. Safe glyphs and NO_COLOR keep the structure with ASCII markers and backticks.

Links are now judged on their whole text: no destination is revealed only when the text names exactly the target's host as a whole hostname and no other; internationalized (punycode) hosts are always shown. - Numeric entities decoded after the caller's scrubber, so ‮ and similar could reintroduce bidi overrides or invisible characters. Entities now refuse controls, format characters, separators and private use, and the renderer scrubs its own input instead of trusting callers. - Several recognizers backtracked quadratically on long lines (heading, fence, rule, hard and soft breaks, YAML keys, code spans, emphasis, link brackets, long-word breaking). They are linear scans or bounded searches now, with timing tests on pathological inputs. --- src/markdown/blocks.ts | 90 +++++++++++++++++++++++++++++------- src/markdown/highlight.ts | 9 +++- src/markdown/inline.ts | 75 +++++++++++++++++++++++++----- src/markdown/render.ts | 60 +++++++++++++++++++----- tests/markdownRender.test.ts | 42 +++++++++++++++++ 5 files changed, 235 insertions(+), 41 deletions(-) diff --git a/src/markdown/blocks.ts b/src/markdown/blocks.ts index d3164959..6ed72200 100644 --- a/src/markdown/blocks.ts +++ b/src/markdown/blocks.ts @@ -27,9 +27,6 @@ export interface ListItem { const MAX_DEPTH = 12;

Bypassing every permission check is never sent; refusals are reported as the provider worded them. - The initialize response is kept: the model catalog with per-model effort levels, the provider's commands (built-in or not), agents, output styles and account plan. - Telemetry with provenance (provider, requested, observed, estimate): runtime facts from each turn's init, usage and cost, rate limits (shared only with targets of the same launch profile, labelled), compaction, retries, tasks, the TodoWrite plan and the files tools read and edited, with the provider's own patch hunks. - Structured tool results (patches, reads, command output, searches, plans, subagent reports), bounded, never keeping whole file contents. - Permission requests carry the provider's reason and its own rule offers; an accepted offer is returned verbatim, never composed by NMSh. - Streaming text (--include-partial-messages) is presentation only and is replaced by the completed message; a profile's effort is a launch flag. --- src/agents/sessions/claudeAdapter.ts | 196 +++++++++++++-- src/agents/sessions/claudeStream.ts | 343 +++++++++++++++++++++++++ src/agents/sessions/manager.ts | 94 ++++++- src/agents/sessions/model.ts | 59 ++++- src/agents/targets/adapter.ts | 2 +- src/agents/telemetry.ts | 361 +++++++++++++++++++++++++++ tests/agentControlPlane.test.ts | 252 +++++++++++++++++++ 7 files changed, 1272 insertions(+), 35 deletions(-) create mode 100644 src/agents/sessions/claudeStream.ts create mode 100644 src/agents/telemetry.ts create mode 100644 tests/agentControlPlane.test.ts diff --git a/src/agents/sessions/claudeAdapter.ts b/src/agents/sessions/claudeAdapter.ts index 36f2e4fb..515506d1 100644 --- a/src/agents/sessions/claudeAdapter.ts +++ b/src/agents/sessions/claudeAdapter.ts @@ -1,6 +1,8 @@ import {spawn, spawnSync, type ChildProcess} from 'node:child_process'; import {randomUUID} from 'node:crypto'; import type {AgentEvent, AgentQuestion} from './model.js'; +import {ClaudeStream, parseCatalog, parseContextUsage, parseSuggestions, parseToolResult, type PartialUpdate} from './claudeStream.js'; +import type {ContextSnapshot, TelemetryUpdate} from '../telemetry.js'; export function claudeQuestions(input: unknown): AgentQuestion[] | undefined { const value = input as {questions?: unknown} | undefined; @@ -32,6 +34,10 @@ export interface ClaudeCapabilities { hostPermissions: boolean; resume: boolean; sessionId: boolean; + /** `--include-partial-messages`: replies stream in as they are written (presentation only). */ + partialMessages?: boolean; + /** `--effort ` at launch. */ + effortFlag?: boolean; } const capabilityCache = new Map(); @@ -46,6 +52,8 @@ export function claudeCapabilities(executable: string, help?: string): ClaudeCap hostPermissions: /--permission-prompts[\s\S]{0,200}"host"/u.test(text), resume: /--resume\b/u.test(text), sessionId: /--session-id\b/u.test(text), + ...(/--include-partial-messages\b/u.test(text) ? {partialMessages: true} : {}), + ...(/--effort\b/u.test(text) ? {effortFlag: true} : {}), }; if (help === undefined) capabilityCache.set(executable, capabilities); return capabilities; @@ -92,11 +100,19 @@ export function resultFailure(message: Record): string | undefi return undefined; } +type ClaudeLine = {events: AgentEvent[]; control?: {requestId: string; subtype: string; tool?: string; input?: unknown}; turnError?: string}; + /** One stdout line → normalized events (unknown shapes produce nothing). */ -export function claudeEvents(line: string): {events: AgentEvent[]; control?: {requestId: string; subtype: string; tool?: string; input?: unknown}; turnError?: string} { - let message: Record; - try { message = JSON.parse(line) as Record; } catch { return {events: []}; } +export function claudeEvents(line: string): ClaudeLine { + let message: unknown; + try { message = JSON.parse(line); } catch { return {events: []}; } + return message && typeof message === 'object' && !Array.isArray(message) ? claudeMessageEvents(message as Record) : {events: []}; +} + +/** One parsed stream-json message → normalized events. */ +export function claudeMessageEvents(message: Record): ClaudeLine { const type = message.type; + const parent = typeof message.parent_tool_use_id === 'string' && message.parent_tool_use_id ? message.parent_tool_use_id.slice(0, 128) : undefined; if (type === 'system' && message.subtype === 'init') { const model = runtimeModel(message.model); return {events: [{kind: 'started', ...(typeof message.session_id === 'string' ? {harnessSessionId: message.session_id} : {})}, ...(model ?

Rows are what Claude published: its model catalog, and only the effort levels the running model supports (none for a model without levels, which the picker says). Up/Down choose, typing filters, Enter applies through set_model or apply_flag_settings, Esc backs out. /model sonnet and /effort high apply directly on an exact match; a leading space sends text verbatim. Nothing is claimed without evidence: a model change reads "requested" until Claude reports it; effort is shown as acknowledged, set at launch, read from the account's settings, or the model default (unreported) - never invented. The header shows model and effort with that provenance. A refusal keeps the picker open with the reason. --- src/agents/claudeSettings.ts | 24 ++++ src/agents/input/controller.ts | 7 +- src/agents/input/pickers.ts | 104 ++++++++++++++++ src/agents/input/surface.ts | 59 +++++++++ src/agents/sessions/AgentViews.ts | 2 + src/agents/sessions/manager.ts | 2 +- src/agents/telemetry.ts | 32 ++++- src/agents/transcript/view.ts | 52 +++++++- src/app/TerminalApp.ts | 19 ++- tests/agentPickers.test.ts | 200 ++++++++++++++++++++++++++++++ 10 files changed, 490 insertions(+), 11 deletions(-) create mode 100644 src/agents/claudeSettings.ts create mode 100644 src/agents/input/pickers.ts create mode 100644 tests/agentPickers.test.ts diff --git a/src/agents/claudeSettings.ts b/src/agents/claudeSettings.ts new file mode 100644 index 00000000..82b69342 --- /dev/null +++ b/src/agents/claudeSettings.ts @@ -0,0 +1,24 @@ +import {readFile} from 'node:fs/promises'; +import {homedir} from 'node:os'; +import {join} from 'node:path'; +import {EFFORT_LEVELS} from './sessions/claudeAdapter.js'; + +/** + * The effort level Claude Code would start with for a launch identity and directory, read passively from the settings + * files Claude documents (user, then project, then local; later wins).

The old inventory read projectEnabled, which is false for nearly every installed plugin, so everything showed disabled; project and local enabledPlugins overrides are now read and named instead. - Conflicts (also installed at another scope, other version), dependencies and options, in words; project installations of other directories are not shown. - What it does in an NMSh-managed session, per Claude's documented behavior for claude -p: a mod's hooks run, nothing it draws appears; skills, agents, commands, hooks, MCP and LSP load.
