## Cursor-free results and spill
Neither search tool exposes a cursor, offset, page size, or model-controlled result limit. One execution follows provider cursors while the observed generation remains valid and collects up to the configured `maxSearchResults`, which defaults to 100. A capped result tells the model to narrow its query or filters; a generation change reports that the whole search must be retried. Search execution carries a configurable `searchTimeoutMs`, defaulting to 30 seconds, through the tool deadline and the service abort signal.
Neither search tool exposes a cursor, offset, page size, or model-controlled result limit. One execution follows provider cursors while the observed generation remains valid and collects up to the configured `maxSearchResults`, which defaults to 100. A capped result tells the model to narrow its query or filters; a generation change reports that the whole search must be retried. Search execution carries a configurable `searchTimeoutMs`, defaulting to 30 seconds, through the tool deadline and the service abort signal. Because internal pages share generation-bound cursors, both search tools are exclusive in the agent-loop scheduler; the exact trace and read tools opt into parallel sibling execution because their observations tolerate intervening commits.
Trace and read tools likewise expose no lineage or character pagination. Canonical results are plain text and remain complete within the service's existing event-window and search-count resource bounds. The generic `tools/post-execute` spill policy owns inline byte retention: when a configured deployment receives oversized text, it replaces that text with a bounded preview plus an opaque locator and retrieval hint while preserving the complete result in its spill store. The session-query consumer neither imports `ctx.spillStore` nor implements a second truncation format.
Session-level results include the latest folded title when available. Each tool execution batches its unique title ids through one live-preferred corpus observation with at most four persisted-inspection workers and passes the exact tool-execution signal through persisted listing and inspection. Live sources fold directly; each persisted worker folds its completed source to a detached header/title observation and releases the full log before dequeuing another id, so the batch retains only small projected values. For the search tools, the execution signal carries the configured search deadline. Cancellation starts no queued title inspections and rejects the complete tool execution after already-started inspections settle; a missing, malformed, or operationally failed title remains isolated to that id, preserves the base result, renders an unavailable marker, and logs the underlying error, while an authorization mismatch fails closed. Search results include the strongest matching event and provider excerpt, traces include complete authorized relationships, and event reads keep neighbor presentation readable while reserving exact JSON for the requested target.

## Verification
Package tests pin argument validation, filter translation, timestamp normalization, exact-workspace authorization, changed-observation rejection, missing-identity behavior, hidden-boundary pruning, current-step exclusion, internal provider paging, count caps, cancellation, one-scan bounded batch title enrichment, projection-before-dequeue ordering, queued-work suppression, started-worker quiescence, per-header validation, title fallbacks, representative search/trace/read rendering, generic presentation, and disposable registration. Integration coverage uses the real SQLite FTS provider over live and persisted sessions. Loader and assembled-host coverage proves that ACP, TUI, and Web register the tools with timeout and spill support, while keyless assembled ACP snapshots pin the prompt guidance and schemas plus path-independent exact event-read spill and retention behavior.

## Consequences
Models gain provider-independent access to prior session work without receiving storage authority or continuation state. Search has a finite per-call work bound and may require a narrower query to reach matches beyond the first 100; complete traces and event payloads may become spill references instead of inline text. Exact string `cwd` equality favors a conservative security boundary over resolving symlink-equivalent paths. Custom compositions may mount the tool without spill, but then they explicitly accept complete inline trace and read results.

## 无游标结果与 spill
两个搜索工具都不向模型公开游标、偏移量、页大小或模型可控的结果限制。一次执行会在观察到的代保持有效时持续跟随提供方游标，并收集不超过配置项 `maxSearchResults` 的结果，其默认值为 100。达到上限的结果会要求模型缩小查询或过滤范围；代发生变化时会报告必须重试完整搜索。搜索执行通过工具截止时间与服务中止信号传递可配置的 `searchTimeoutMs`，默认值为 30 秒。

追踪与读取工具同样不公开谱系分页或字符分页。规范结果采用纯文本，并在服务已有的事件窗口与搜索数量资源边界内保持完整。通用的 `tools/post-execute` spill 策略负责行内字节保留：当已配置的部署收到过大的文本时，该策略会用有界预览、不可透明推导的定位符与读取提示替换文本，同时在 spill 存储中保留完整结果。会话查询消费者既不导入 `ctx.spillStore`，也不实现第二套截断格式。
会话级结果在可用时包含最新折叠标题。每次工具执行都会通过一次优先使用实时数据的语料观测批量读取唯一标题 id，最多使用 4 个持久化检查 worker，并将准确的工具执行信号传递给持久化列表与检查操作。实时来源会直接折叠；每个持久化 worker 都会把已完成的来源折叠为分离的会话头／标题观测，并在取出下一个 id 前释放完整日志，因此批次只保留小型投影值。对于搜索工具，该执行信号携带已配置的搜索截止时间。取消不会启动排队中的标题检查，并会在已经启动的检查全部完成后拒绝完整的工具执行；标题缺失、格式错误或发生操作性失败时，错误只影响对应 id，同时保留基础结果、渲染不可用标记并记录底层错误，而授权不匹配则按失败关闭处理。搜索结果包含最强匹配事件与提供方摘录，追踪包含完整的已授权关系，事件读取保持邻近事件表现易读，同时只为被请求的目标保留精确 JSON。

## 后果
模型无需获得存储权限或继续状态，即可通过与提供方无关的方式访问既往会话工作。搜索具有有限的单次调用工作边界，若要命中前 100 条以后的结果，可能需要缩小查询；完整追踪与事件负载可能表现为 spill 引用而不是行内文本。严格的 `cwd` 字符串相等选择了保守安全边界，而不解析通过符号链接等价的路径。自定义组合可以在不挂载 spill 的情况下使用该工具，但这表示它们明确接受完整追踪与读取结果直接出现在行内。
