`Session.toolHistory()` caches a capability-independent fold of committed headers and developer messages. First access restores inherited events; later reads consume only unseen events. Immutable snapshots carry initial declarations and ordered update identities with additions resolved through their historical headers. Explicit series starts and changed retained definitions rebuild declarations. Restoring a retained name with an unchanged definition continues the series: the projection keeps the declaration unchanged and lets the recorded addition re-offer the tool after its earlier removal, so a removal never disables a declared tool and a loading mode never rewrites an earlier declaration.
Loop and compaction requests carry this snapshot as `GenerateOptions.toolHistory`. At adapter dispatch, `projectToolUpdates` uses the prepared route's `toolUpdate`. Unsupported routes receive active definitions without `deferLoading` or developer messages. Supported routes defer historical additions; `in-history` retains removed definitions and removal blocks, while `addition-only` omits both. Only current-series update identities survive. Missing history or a request prefix omitting recorded updates uses current declarations without developer updates. Explicit deferred loading remains available on capable routes.

Unsupported routes receive active definitions without `deferLoading` or developer messages. Supported routes defer historical additions; `in-history` retains removed definitions and removal blocks, while `addition-only` omits both. On addition-only routes, removing any tool rebuilds the route's baseline after that update: the request declarations change even when the removed tool was activated later, so retaining superseded activation blocks cannot preserve the full conversation prefix. Adding tools when no declarations exist also rebuilds the baseline. Deferred declarations count as existing tools. The first native tool changes the empty declaration prefix; deferring it provides no cache advantage over declaring it immediately. Previously activated tools become immediate; explicitly deferred declarations with no activation remain deferred. Subsequent additions remain deferred until their recorded activation. Superseded tool blocks are omitted without discarding other content in those messages. The Session fold and durable events remain capability-independent. Missing history or a request prefix omitting recorded updates uses current declarations without developer updates.
DeepSeek translates projected updates into system-role `tool_addition` and `tool_removal` blocks and `defer_loading` declarations, sending the tool-changes beta header when update blocks occur. The default `deepseek-flash` entry declares `addition-only`; pi-ai declares no mode. Chat and Trajectory display developer messages as context nodes, using localized tool-change notices: single changes show the tool name; multiple changes show counts and expandable name lists.

**Scan the complete log on every request.** The cached fold consumes new events and supplies stable snapshots to ordinary and auxiliary calls without adding arbitrary synchronous history readers.
**Rebuild the baseline on every removal.** Deferred tools also have request declarations; deleting a tool changes those declarations regardless of its activation position. Addition-only routes cannot express that deletion in history. The rebuild therefore also covers removal-only updates and removals of later-activated tools. A past reset cannot force every future addition to become immediate: each reset establishes a new baseline from which deferred additions resume.
**Reject same-name schema changes during tool registration.** This restriction is not enforced. Immediate failure for a plugin registering an incompatible tool requires comparing the new registration with historical definitions of tools called on each affected current surface, while excluding calls removed by compaction. That registration-time historical and scope-aware check is deferred because of its implementation complexity. Same-name schema changes remain allowed; they rebuild declarations and invalidate prefix reuse even on `in-history` routes.

# Agent Note: Expose DeepSeek deferred-only request failures
Status: implemented
English | [中文](2026-11-02-deepseek-deferred-tool-failures.zh.md)
## Problem
A synthetic immediate tool can make an all-deferred DeepSeek request acceptable while hiding an invalid tool-update projection. It also changes the request prefix and advertises a tool with no executor.
## Decision
The DeepSeek adapter sends deferred declarations unchanged and propagates provider rejection. This replaces the placeholder accommodation described by the [tool-update decision](../architecture/2026-09-20-dynamic-tool-updates.md), whose shared history projection remains authoritative.
Ordinary addition-only histories start with native tools or an empty set. Removals and first additions to an empty set rebuild native declarations; later deferred additions retain a native baseline. Explicit deferred-only registrations, direct adapter calls, and custom in-history routes can still produce all-deferred requests. Those configurations receive no adapter workaround.
## Alternatives considered
**Keep a synthetic immediate tool.** It conceals unexpected deferred-only requests and cannot preserve a prefix that lacked that tool. Automatically activating a real tool instead changes its declared availability.
**Reject locally.** Provider validation owns acceptance; another local restriction would duplicate it. Reconsider accommodation only for a supported workflow that requires deferred-only requests and cannot retain a native declaration.
## Consequences
Deferred-only compatibility is deliberately given up so request errors remain visible. Serializer and HTTP tests verify exact declarations and propagation of a provider rejection. The all-deferred keyless snapshot verifies request construction only; replay success does not establish provider acceptance. Replacement and empty-set scenarios verify the supported addition-only path.

# Agent Note: 显露 DeepSeek 全延迟请求失败
Status: implemented
[English](2026-11-02-deepseek-deferred-tool-failures.md) | 中文
## Problem
合成的立即加载工具可使 DeepSeek 接受全延迟请求,却掩盖无效的工具更新投影。它还会改变请求前缀,并声明一个没有执行器的工具。
## Decision
DeepSeek 适配器原样发送延迟声明,并传递提供方的拒绝错误。这取代了[工具更新决策](../architecture/2026-09-20-dynamic-tool-updates.zh.md)中描述的占位工具兼容机制;其中的共享历史投影仍是权威依据。
普通 addition-only 历史以原生工具或空集开始。移除工具或首次向空集添加工具会重建原生声明;后续延迟添加保留原生基线。显式全延迟注册、直接调用适配器和自定义 in-history 路由仍可产生全延迟请求。适配器不为这些配置提供变通处理。
## Alternatives considered
**保留合成的立即加载工具。** 它会掩盖意外的全延迟请求,也无法保留原本没有该工具的前缀。改为自动激活真实工具则会改变其声明的可用性。
**在本地拒绝。** 是否接受请求由提供方验证决定;额外的本地限制会重复该验证。只有受支持工作流确实需要全延迟请求,且无法保留原生声明时,才重新考虑兼容处理。
## Consequences
有意放弃全延迟兼容性,使请求错误保持可见。序列化和 HTTP 测试验证精确声明以及提供方拒绝错误的传递。全延迟无密钥快照仅验证请求构造;回放成功不代表提供方接受。替换和空集场景验证受支持的 addition-only 路径。

description: "One web_search call accepts 10 queries and returns 10 sources by default, and the DeepSeek Search API provider paces its requests."
---
# Web search defaults
English | [中文](guide.zh.md)
## Change
In `dsh-tool-web`, the `searchMaxQueries` default rises from 4 to 10 and the `searchMaxResults` default rises from 8 to 10. The `web_search` schema now advertises `1–10 search queries`, so a call with 5–10 queries runs instead of failing validation, and each call can return up to 10 sources. A call can therefore start more provider searches and add more source text to the context. With the shipped Messages search provider, each query is one auxiliary model request. `dsh-web-deepseek-api` adds `searchRequestsPerSecond`, default 5: its Search provider sends at most that many requests in any one-second window, so the second five queries of a 10-query call start one second after the first instead of exceeding the account's 5 QPS limit. Values that a deployment already sets are kept.
## Migration
1. To keep the previous limits, set `searchMaxQueries: 4` and `searchMaxResults: 8` in the `tool-web` entry's `config` in `cordis.patch.yml`.
2. If several processes share one DeepSeek account through the Search API, lower `searchRequestsPerSecond` in the `web-deepseek-api` entry so that their combined rate stays at or below 5.
3. Confirm the result by running a task that sends 10 queries in one `web_search` call: it returns results instead of `Error: queries must contain at most 4 queries`. See the [tool-web configuration](../../../../packages/web/tool-web/README.md).

description: "一次 web_search 调用默认接受 10 个查询并返回 10 个来源,DeepSeek Search API 提供方会为请求限速。"

# Web 搜索默认值
[English](guide.md) | 中文
## 变更
在 `dsh-tool-web` 中,`searchMaxQueries` 默认值从 4 提高到 10,`searchMaxResults` 默认值从 8 提高到 10。`web_search` 的 schema 现在公布 `1–10 search queries`,因此含 5–10 个查询的调用会执行,而不是校验失败;每次调用最多返回 10 个来源。因此一次调用可能发起更多提供方搜索,并向上下文加入更多来源文本。使用内置的 Messages 搜索提供方时,每个查询都是一次辅助模型请求。`dsh-web-deepseek-api` 新增 `searchRequestsPerSecond`,默认 5:其 Search 提供方在任意一秒窗口内最多发送这么多请求,因此 10 个查询的调用中后五个查询比前五个晚一秒开始,而不会超过账号的 5 QPS 限制。部署已设置的值保持不变。
## 迁移
1. 如需保留原上限,在 `cordis.patch.yml` 的 `tool-web` 条目 `config` 中设置 `searchMaxQueries: 4` 和 `searchMaxResults: 8`。
2. 如果多个进程通过 Search API 共享同一个 DeepSeek 账号,在 `web-deepseek-api` 条目中调低 `searchRequestsPerSecond`,使它们的合计速率不超过 5。
3. 运行一个在一次 `web_search` 调用中发送 10 个查询的任务来确认:调用返回结果,而不是 `Error: queries must contain at most 4 queries`。参见 [tool-web 配置](../../../../packages/web/tool-web/README.zh.md)。

#### What the model sees
The selected DeepSeek model receives the harness system prompt, message history, tool schemas, stop sequences, and call config (`maxTokens`, `reasoningEffort`, `temperature`) without adapter-authored prompt prose. Provider-specific request-extension fields remain outside model input. The vision model normally receives retained user and tool-result images as Files API references beside attachment handles and request-preview dimensions. It also receives a normalized-object path when the current execution filesystem maps the attachment provider's host object; the descriptor marks this copy read-only and warns that normalization may have resized or re-encoded the upload. A Files resolution failure sends all retained images as inline base64 instead, and an over-budget older image keeps the access resolved for that request in its placeholder. Reasoning content from a prior assistant turn is passed back verbatim, whether or not that turn called a tool. Messages sends `{}` for historical tool arguments that are malformed JSON or are not objects. This argument fallback preserves call ids, tool names, and tool results; the original arguments stay in the Session log. Newly generated Messages tool arguments still require valid JSON objects. Messages omits `reasoning` and `tool-call` blocks inside user messages and tool results. This also permits replay of saved subagent notices containing assistant output; the original Session content remains intact. Empty user messages are skipped after conversion, while empty tool results retain their call ids and error flags. Other unsupported input blocks still fail with `UNSUPPORTED_CONTENT`.

### Pinning request headers and system prompts
A pin owns its generated `system-prompt.expected.md` or `tool-schemas.expected.json` sidecar by default; `systemPromptSource` and `toolSchemasSource` name another pin when the complete corresponding sequence is identical, so each distinct version is committed once. The system prompt is surface node 0, logged as a `system/message` event before the step's first `request/header`; every fixture stores its text block as `"text":"{{system}}"` and the prompt sidecar keeps the full text. The pin's `request/header` events store `"tools":"{{tools}}"` while retaining config and reason, and the structured schema sidecar keeps the full catalogs. Logs containing developer messages retain ordered tool names in each header instead of the token so historical addition references remain verifiable. A child Session whose own scope composes a different request declares it per fixture index with `pinsChildToolSchemas` and `pinsChildSystemPrompts`. A scenario that changes the request header mid-run declares `expectedHeaderChanges`; a scenario whose prompt changes mid-run — replacing node 0, or appending after the cached history on an `in-history` route — declares `expectedPromptChanges`, and each change adds a `<!-- system/message change N -->` section to the prompt sidecar. The manifest spells these `header.changes` and `header.promptChanges`.

These limits define when the tools are incomplete or need deployment cooperation. They are current package constraints.
- **There is no batch-wide native-search counter** — `searchMaxQueries` bounds `ctx.web.search` calls, but a provider may perform several native searches inside each call; for example a model-backed provider configured with `maxUses` can permit up to `searchMaxQueries × maxUses` native searches, and `searchMaxResults` limits only the combined sources returned to the caller. Deployments control cost through these independent consumer and provider settings because the service does not know provider-internal search units.
- **One failed query fails the whole call** — queries in one call run concurrently, and the first provider failure aborts the rest and discards results that already succeeded. A provider rate limit therefore fails the call; [`dsh-web-deepseek-api`](../web-deepseek-api/README.md#known-limitations-and-deferred-work) paces its own Search requests to the account's 5 QPS limit within one process.
- **HTML→markdown conversion omits inputs it cannot safely represent** — [turndown](https://github.com/mixmark-io/turndown) converts at most `fetchMaxOutputChars` source characters through a real DOM. A 512-level nesting guard and conversion exceptions produce a fixed omission marker instead of raw HTML; table `colspan` remains unsupported because GFM has no spanning-cell representation ([archived dependency decision](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)).
- **The model-facing API is minimal by design, with promotions deferred** — `max_results` stays a config bound (not a model argument), and `web_fetch` takes only `url` (no `format`/`prompt`/LLM-summarization mode); both are named later steps in [the seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md).
- **Fetches do not request approval** — the shipped `cordis`, `code`, and `standard` presets expose `web_fetch` in every sandbox and approval mode. The HTTP provider does not restrict destination addresses, so a model can reach loopback and private-network hosts and send data to any reachable URL. Deployments that need per-call confirmation must add a `tools/pre-execute` policy or disable fetch.

- **没有覆盖整个批次的原生搜索计数器**:`searchMaxQueries` 限制 `ctx.web.search` 调用数,但提供方可以在每次调用内执行多次原生搜索;例如,配置了 `maxUses` 的以模型为后端的提供方最多可以执行 `searchMaxQueries × maxUses` 次原生搜索,`searchMaxResults` 只限制返回给调用方的组合来源。部署通过这些独立的消费方与提供方设置控制成本,因为服务不知道提供方内部的搜索计量单位。
- **一个查询失败会使整次调用失败**——一次调用中的查询并发执行,首个提供方失败会中止其余查询并丢弃已成功的结果。因此提供方限流会使调用失败;[`dsh-web-deepseek-api`](../web-deepseek-api/README.zh.md#known-limitations-and-deferred-work) 在单个进程内把自己的 Search 请求限制在账号的 5 QPS 以内。
- **HTML→markdown 转换会省略无法安全表示的输入**——[turndown](https://github.com/mixmark-io/turndown) 会通过真实 DOM 转换至多 `fetchMaxOutputChars` 个源字符。512 层嵌套守卫与转换异常会产生固定省略标记,而不是返回原始 HTML;表格 `colspan` 仍不受支持,因为 GFM 无法表示跨列单元格([已归档的依赖决策](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md))。
- **面向模型的接口有意保持精简,后续扩展暂缓**:`max_results` 保持为配置上限(不是模型参数),`web_fetch` 只接受 `url`(没有 `format`/`prompt`/LLM(大语言模型)摘要模式);两项都列为 [seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.zh.md) 中的后续步骤。
- **抓取不请求审批**——随产品交付的 `cordis`、`code` 与 `standard` preset 在所有 sandbox 和审批模式下公开 `web_fetch`。HTTP 提供方不限制目标地址,因此模型可以访问 loopback 与内网主机,并向任何可访问的 URL 发送数据。需要逐次确认的部署必须添加 `tools/pre-execute` 策略或禁用抓取。

- In 2026-10-16 probes, different `ori_question` values left result order, scores, and summaries unchanged; the provider still sends it because the guide documents it as an intent signal.
- API query and URL constraints are enforced by the remote service. An unresolvable Fetch target returned HTTP 500 rather than the documented 404 on 2026-10-16, and its failure carries the same endpoint guidance as an endpoint failure. Fetch exposes neither the target status nor the final redirect URL, so results report HTTP 200 and the requested URL; the provider discards the API's page title.
- `available()` cannot query asynchronous credential stores; `ready()` does, so model steps withhold the tools when the store lacks the key. A direct `ctx.web.search()` or `ctx.web.fetch()` call can still fail with a missing-credential error.
- Search pacing limits send times within one plugin instance. Other processes and clients on the same account share the account-wide 5 QPS limit without coordination, and network jitter can still bunch arrivals; an HTTP 429 fails that search, and `dsh-tool-web` then fails the whole multi-query call. Fetch is not paced, so parallel `web_fetch` calls can exceed the Fetch limit.
- When the official route chats through a gateway, operations still send the key to the configured API base and fail unless it accepts the key.

You are an AI agent powered by DeepSeek Harness.
You are a coding assistant powered by the deepseek-v4-flash model. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
Verify your work by running the code or tests. Keep answers brief and factual.
Check the [exit code: N] marker on every bash result; investigate failures before moving on.
Track every background job id you start. You are notified in-session when a job finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running job's work. Before giving a final answer, collect every still-relevant job with job_output (set wait: true only when you are genuinely blocked on it), and job_kill jobs that stopped mattering.
create_goal may infer goal intent from a direct human request in any language. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.

You are an AI agent powered by DeepSeek Harness.
You are a coding assistant powered by the deepseek-v4-flash model. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
Verify your work by running the code or tests. Keep answers brief and factual.
Check the [exit code: N] marker on every bash result; investigate failures before moving on.
Track every background job id you start. You are notified in-session when a job finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running job's work. Before giving a final answer, collect every still-relevant job with job_output (set wait: true only when you are genuinely blocked on it), and job_kill jobs that stopped mattering.
create_goal may infer goal intent from a direct human request in any language. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
