feat(core,cli): M3c — compaction + statusLine + CLI flag wiring#11
Merged
Conversation
What ships
----------
- packages/core/src/compaction/index.ts
compact(history, {provider, keepFirstPairs, keepLastMessages, summarizerModel,
summaryMaxTokens}) → CompactionResult{history, messagesRemoved, usage,
summaryText}. Strategy: anchor head + summarized middle + recent tail.
shouldCompact({inputTokens, outputTokens, contextWindow, threshold}) helper.
- packages/core/src/harness/statusline.ts
StatusLineRunner — periodic exec with JSON-on-stdin payload (session_id,
model, cwd, mode, effort, transcript_path, cost, version, output_style).
Respects DEEPCODE_STATUS_LINE_DEBOUNCE_MS env override. 200-char output cap.
2s command timeout. Suppress EPIPE for scripts that don't read stdin.
Only fires onUpdate when stdout actually changes.
runStatusLineCommand standalone helper for one-shot use.
- apps/cli/src/repl.ts — wire CLI args into agent loop:
· systemPromptOverride / appendSystemPrompt / appendSystemPromptFile
· allowedTools / disallowedTools (filter BUILTIN_TOOLS before ToolRegistry)
· maxTurns
- apps/cli/src/cli.ts — pass parsed flags into startRepl
Tests (16 new, 281 total)
-------------------------
- compaction/index.test.ts (8): short-history-unchanged, compact-middle,
preserve-anchor + tail, summarizerModel override, usage reporting,
tool_use/tool_result rendering in summary prompt, shouldCompact threshold
- harness/statusline.test.ts (8): trimmed stdout, stdin payload, 200-char cap,
timeout → empty, exit-nonzero → empty, empty config → empty, Runner only
fires onUpdate when text changes, env-var debounce override
Verified
--------
pnpm typecheck → green
pnpm test → 240 + 41 = 281 passed / 0 failed
pnpm format:check → conformant
Deferred to next M3c PR
-----------------------
- Auto compaction trigger inside agent loop (wire shouldCompact post-turn)
- StatusLine actual REPL rendering
- /init multi-phase, auto classifier, remaining 4 hook handler types

…esize (#11) (#145) * feat(desktop): right-side file panel — Source/Diff/History + tabs + resize (#11) Implements the §3.11 file panel (Mac client). Inserts a 4th grid column between the chat stream and the 48px inspector rail (the inspector stays a rail while a file is open). - FilePanel.tsx — pure presentational component: multi-file tab bar (close ×, unsaved yellow dot), Source/Diff/History view switcher, Source (line-numbered read-only), Diff (inline +/- and side-by-side split, ⌘\ toggles), History (session version timeline), and a left-edge resize grip. - file-panel-reducer.ts (+ 9 unit tests) — pure tab/view/width state machine. - use-file-panel.ts — wraps the reducer with file reads (tool_read), width persistence (localStorage, 320–800px), and the ⌘O / ⌘[ / ⌘] keybindings. - App.tsx — renders the panel + the .file-open grid track, the resize drag, and makes ⌘\ context-sensitive (diff split/inline when a diff is showing, else the inspector toggle). Inspector "Recent files" rows now open into the panel. - tauri-api.ts — toolRead() wrapper over the unscoped tool_read command. Verified visually via a dev-only vite preview harness (src/preview.html, not in the prod bundle) screenshotted across all three views. Diff/History render from data the parent supplies; the snapshot-backed wiring (so Edit/Write populate them) + the click-a-file-in-chat trigger land in a follow-up — honest empty states meanwhile. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(desktop): file panel must not flex-shrink below its dragged width flex-shrink: 0 so the panel keeps its set width (320–800px) in any flex context; the real app's grid `auto` track already sizes to it, this also makes the standalone preview harness respect the width.
