概述

本 PR 含两类改进 + 一处 CI 调整。

1. 上下文压缩改为软硬两级触发

背景:现只在上下文达到窗口 90% 时才做完整摘要压缩。而大量实践(Anthropic 的观察)表明上下文利用率超过约 40% 后模型质量就明显退化,90% 触发偏晚,等于让 Agent 长时间在"变笨区"里跑。

  • 软阈值(默认 60%):只静默精简历史里的超长工具输出(不调用摘要模型、不发事件、不落库),让上下文尽量停留在退化区以下。
  • 硬阈值(默认 85%,原 90%):才走完整摘要压缩。
  • tail 去垃圾:软精简统一作用到全部历史(含最近保留区),避免超长工具输出原样占用主上下文。
  • 结构化接手摘要:compact-summary.md 改为固定分节模板(任务目标 / 关键决定与理由 / 当前进度 / 未完成下一步 / 约束与偏好 / 关键数据),提升接手续接质量。
  • 设置页新增**「软精简阈值」**配置项(1-100)。

2. 附件上传并发覆盖修复

  • 现象:附件上传中再次上传,先选文件的预览丢失(但文件已上传成功)。
  • 根因:pendingAttachments = pendingAttachments + uploaded 是读-改-写,两次上传并发时后写覆盖前写。
  • 修复:AIChatPanel.handlePickedAttachments 用 Mutex 串行化上传流程。
  • 顺带:待发送附件缩略图区保持横向滑动,新加入的附件自动滚到最右、立即可见。

3. CI

  • ci.yml 增加一步,把 universal debug APK 上传为 artifact,便于直接下载安装验证。

验证

  • CI:编译 + 961 项单元测试通过。
  • Beta:正式签名构建通过。

说明

第 3 点(ci.yml 上传 debug APK)是为便于验证而加,如上游不需要可在合并前剔除。

Summary by CodeRabbit

  • New Features
    • Added remote SSH workspace skills to settings, with connection status and options to browse, import, edit, and delete skills.
    • Added a configurable soft context threshold, defaulting to 60%, that trims long tool outputs without summarizing conversation history.
  • Improvements
    • The full summarization threshold now defaults to 85%, down from 90%.
    • Newly added attachments scroll into view, and simultaneous attachment uploads are handled in sequence.

- 两级触发: 软阈值(默认60%)只静默精简历史超长工具输出(不调LLM), 硬阈值(默认85%, 原90%)才做完整摘要压缩
- tail 去垃圾: 软精简统一作用到全部历史(含最近保留区), 避免超长工具输出原样进主上下文
- 结构化接手摘要: compact-summary.md 改为固定分节模板(目标/决定/进度/未决/约束/关键数据)
- 设置页新增'软精简阈值'项(1-100) + 双语文案
- handlePickedAttachments 用 Mutex 串行化: 两次上传并发时 pendingAttachments 读-改-写互相覆盖, 先选附件预览丢失
- PendingAttachmentPreviewList 保持横向滑动, 新附件加入自动滚到最右保证可见

📝 Walkthrough

Walkthrough

The pull request adds remote SSH skill management to settings, configurable soft context trimming, and a structured summary prompt. It also serializes attachment uploads, scrolls attachment previews to new items, and uploads the universal debug APK from CI.

Changes

Remote Skill Management

Layer / File(s) Summary
Remote file access and skill repository
app/src/main/java/com/aicode/feature/workspace/domain/RemoteSkillFileAccess.kt, app/src/main/java/com/aicode/feature/agent/domain/skill/SkillRepository.kt
Adds SFTP file operations and provider/root-based skill scanning, saving, importing, and deletion.
Remote skill operations
app/src/main/java/com/aicode/feature/agent/domain/skill/RemoteSkillsManager.kt, app/src/main/java/com/aicode/feature/settings/presentation/SettingsViewModel.kt
Adds remote connection state and operations for scanning, saving, deleting, and importing skills.
Remote skills settings UI
app/src/main/java/com/aicode/feature/settings/presentation/SkillSource.kt, app/src/main/java/com/aicode/feature/settings/presentation/SettingsViewModel.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SettingsScreen.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SkillAddSheet.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SkillEditorScreen.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SkillsSection.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SkillDetailSection.kt, app/src/main/res/values*/strings.xml
Adds Remote as a skill source and displays remote skill state in settings. Remote entries support editing, importing, and deletion, and do not show the local enable switch or enabled/disabled badge.

Context Compaction

Layer / File(s) Summary
Compaction threshold settings
app/src/main/java/com/aicode/feature/settings/data/repository/GeneralSettingsRepository.kt, app/src/main/java/com/aicode/feature/settings/presentation/SettingsViewModel.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/SettingsScreen.kt, app/src/main/java/com/aicode/feature/settings/presentation/component/GeneralSettingsSection.kt, app/src/main/res/values*/strings.xml
Adds a persisted soft threshold defaulting to 60%, changes the hard threshold default to 85%, and adds a settings control that accepts values from 1 to 100.
Soft trimming and full compaction
app/src/main/java/com/aicode/feature/agent/domain/workflow/ContextCompactor.kt, app/src/main/assets/prompts/agent/compact-summary.md
At the soft threshold, trims tool results longer than 3,000 characters without calling the summary model. Forced or hard-threshold compaction uses the existing summary flow. The prompt specifies six required handoff sections.

Attachment Handling

Layer / File(s) Summary
Serialized attachment uploads
app/src/main/java/com/aicode/feature/agent/presentation/component/AIChatPanel.kt
Serializes upload batches with a remembered mutex. Per-file failures are collected, and the upload count resets in finally.
Attachment preview scrolling
app/src/main/java/com/aicode/feature/agent/presentation/component/ChatInputAttachments.kt
Remembers the horizontal scroll state and animates the row to its end when the attachment count changes.

CI APK Artifact

Layer / File(s) Summary
Universal debug APK upload
.github/workflows/ci.yml
Uploads the universal debug APK after unit tests. The artifact name includes the commit SHA, and a missing APK produces a warning.

Merge Risk: 🟡 Moderate · up to f00b0

Remote skill management can crash the app when the server is not connected. It can also keep using an old workspace or old credentials after the settings change. Attachment uploads can still exceed the pending limit. Fix these issues before merging.

Security Architecture Review

Security architecture risk: 🟠 High · up to f00b0

Remote skill operations can continue using an earlier account or workspace after connection settings change, and an operation already in progress may reconnect after a disconnect. These risks are limited to configured remote connections, but they affect which account can read or change remote files.

Retained concerns

  • High · security · inferred: Changing the port, credentials, or workspace on the same host does not replace the cached remote access object. Subsequent skill reads or mutations can use the former account or workspace rather than the selected settings.
  • Medium · security · inferred: An operation that captured the access object before disconnect can use it afterward: closing its channels does not revoke the object, and a later operation reconnects with its original credentials. Concurrent disconnect and mutation therefore lack a terminal revocation boundary.
Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is to files reachable by a configured SSH account and the remote skill operations, not to an unauthenticated network entrypoint. Same-host identity reuse can nevertheless direct an operation to the previous account or workspace.

Security Findings and Attack Paths

  • inferred — After a same-host account or workspace switch, the settings operation can cross into the old SSH identity and write or delete its skill files. An in-flight operation retaining that access object can also reconnect after disconnect. Both paths require a configured connection and an operation through the new remote skill flow.

Trust Boundaries and Controls

  • observed — Host-key verification and password authentication protect new SSH connections. Path mapping also accepts absolute provider paths without imposing a skill-root boundary itself; current manager calls instead supply a fixed root and repository-derived names. Symlink behavior on the remote server remains unverified.

Resilience and Maintainability Implications

  • inferred — Per-call locking does not make remote imports or edits atomic. Repetition, concurrency, or interruption can leave skill state different from the last published scan, complicating recovery and the assurance that displayed state matches remote files.

Hardening Proposals

  • proposed — Bind cached access to the complete connection and workspace identity, and make disconnect revoke outstanding access so a held reference cannot reconnect after the user disconnects.
  • proposed — Establish remote skill-root containment at the filesystem boundary, including symlink handling, and define atomic or recoverable semantics for multi-file imports.

Recheck attachment capacity after acquiring the mutex.

If two picker callbacks run before either upload finishes, both calculate selected from the same pendingAttachments.size at Lines 708–712. The mutex then appends both batches, so the pending list can exceed MAX_PENDING_ATTACHMENTS. Calculate the available slots and select the URIs inside the lock, using the current attachment count.

Scroll after the row updates its maximum bound.

LaunchedEffect runs when it enters composition or its key changes, while horizontalScroll updates maxValue during measurement. The effect can read the previous bound after an attachment is added, so the newest attachment can remain clipped. Key the effect to the updated scrollState.maxValue, or wait for that value to update before scrolling. (developer.android.com)

Keep the soft threshold below the hard threshold.

ContextCompactor.compactIfNeeded soft-trims only when !reachedHard && reachedSoft. If the saved soft threshold is equal to or above the hard threshold, reaching the soft threshold also reaches the hard threshold, so soft trimming cannot run while that ordering remains.

Both setters and both dialogs allow this ordering. Enforce soft < hard in both persisted setters, and revalidate the saved soft threshold when the hard threshold changes. Apply the same constraint in the settings UI.

If the hard threshold later increases above the saved soft threshold, soft trimming can run again. The saved value is not permanently ineffective.

The connection is reused after host credentials or the workspace change.

The access object is rebuilt only when settings.host changes. If the user changes the port, username, password, or remoteWorkspacePath on the same host, the old RemoteSkillFileAccess stays in use. It then scans or writes to the old workspace. Compare the full RemoteSkillConnection instead of only the host.

The SSH connection starts on every Settings entry, not only on the Skills page.

The comment says the connection starts when the user enters the Skills page. The effect is keyed only on executionMode, so it runs as soon as SettingsScreen opens in local mode. This opens an SSH connection even if the user never visits Skills, and it can show a host-key prompt. Key the effect on section == SettingsSection.Skills as well.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Remote save and delete crash the app when access is missing.

remoteSkillsManager.save and delete call requireAccess(), which throws IllegalStateException when the remote is not connected. For example, the user can select REMOTE while the state is Failed or NotConfigured. These coroutines in viewModelScope.launch have no handler, so the uncaught exception crashes the app. Wrap both calls in runCatching. For save, map a failure to SkillSaveState.Failed(SkillSaveError.IO_FAILED).

Proposed fix
-            val error = withContext(Dispatchers.IO) { remoteSkillsManager.save(form, originalName) }
+            val error = withContext(Dispatchers.IO) {
+                runCatching { remoteSkillsManager.save(form, originalName) }
+                    .getOrElse { SkillSaveError.IO_FAILED }
+            }

Hardcoded Chinese error text.

The IOException message on Line 198 is Chinese. This message reaches the UI through RemoteSkillsState.Failed(e.message). Use an English/technical message here, or map the error to a string resource in the UI.
As per coding guidelines: "禁止在 .kt 文件中硬编码中文 UI 文案。"
