fix(core): keep the deferred-tool bridge halves on the same tool (#12539)
* fix(core): keep the deferred-tool bridge halves on the same tool Two findings deferred from #10410 (#11321): F1' - tool_search's select: and tool_call each resolved a model-supplied name case-insensitively with "last match wins" over getAllToolNames(). ensureTool reorders that list when it moves a lazily built tool from the factory map into the tool map, so the two halves could pick different tools for a name that differs from two registered tools only by case. Both halves, and tool_call's classifier projection, now share resolveRegisteredToolName: an exact match wins, a single case-insensitive match is used, and several case-insensitive matches are refused with the candidates listed instead of guessed. R16-1 - tool_call invoked any hidden deferred tool by name, so after the tool's schema or MCP server changed it could run arguments written against a declaration the model no longer holds. tool_search now records a fingerprint (serialized declaration plus MCP server) of each hidden tool it returns, and tool_call refuses a reviewed tool whose fingerprint changed, asking for a fresh select:. A tool never reviewed in the session still works by name, so an unchanged tool costs no extra round trip, including after /compress. Not run locally: vitest, typecheck and eslint are left to CI. The resolution and refusal paths were exercised in a tsx process against the same registry double the tests use. * fix(core): resolve bridged names in the classifier transcript the same way Review of #12539: classifier-transcript.ts still resolved a bridged tool_call target with the last-match loop, so the historical-transcript projection could pick a different tool than tool_call for a name that differs from two registered tools only by case. It now uses resolveRegisteredToolName, and a name matching several tools by case projects name-only, as tool_call refuses it. * fix(core): close four deferred-bridge review findings on #12539 R1-1 (Critical): deferredDeclarationFingerprint hashed the whole schema, including the free-text description. WebSearchTool rebuilds that description from the current month/year on every schema access (web-search.ts:997-1004 -> 916-921) and ReadFileTool rebuilds it from config.getEffectiveInputModalities() (read-file.ts:628-637), both intentionally so a long-lived qwen serve/ACP process is not stale. An unchanged tool's fingerprint therefore drifted across a month boundary or a /model switch and the new tool_call gate refused a legitimate call whose parametersJsonSchema was byte-identical. The fingerprint now covers the invocation contract (server + schema.name + parametersJsonSchema); the getters keep recomputing. The pinned "declaration changed" refusal is retargeted to a parameter-contract change so it stays meaningful. R1-12: the select: parser deduped entries on stripped.toLowerCase(). Since resolveRegisteredToolName makes two names differing only by case two genuinely different tools, that silently dropped one spelling: it appeared in none of missing/truncated/ambiguous, was never recorded as reviewed, and then reached tool_call, which resolves it exactly and takes the never-reviewed pass-through -- the failure #11321 exists to close, via the path the ambiguity message recommended. Dedupe now keys on the resolved identity, so repeated spellings of one tool still collapse while distinct case variants are both reviewed. R1-14: the ambiguity remedy rendered "request the exact name: <rejected>", putting the spelling that is by construction NOT registered into the instruction slot; a model following it literally re-issued a byte-identical select: that loop detection counts as a duplicate. The message now mirrors the twin refusal at tool-call.ts:112 -- the rejected spelling is echoed in quotes and the actionable slot holds select:-able candidates. R1-4: pin the two handshakes the changed-declaration guard depends on. The lookup must key on the resolved target.name (tool_search records under the registered name while models invoke with spellings needing resolution), and recordReviewedDeclaration must overwrite an existing entry so the refusal -> re-review -> recovery loop actually closes. Adds a case-variant refusal case and a real-ToolRegistry integration test that kills both mutants.

R1-10: reclaim a removed tool's reviewed declaration by replacing it with a tombstone instead of retaining the serialized schema for the registry's lifetime. The tombstone can never equal a live fingerprint, so a reconnect that republishes an identical declaration still forces one re-review rather than taking the never-reviewed pass-through. A tool that was never reviewed keeps no entry, so removal cannot grow the map. R1-8: pin the ambiguous -> name-only branch of ToolCallTool.toAutoClassifierInput, the only branch of that projection with no test of its own. R1-3 / R1-2: bring docs/design/deferred-tool-call-bridge.md and its zh-CN counterpart in line with the shipped behaviour — the shared name-resolution rule, the declaration fingerprint and what it deliberately excludes, the remaining presentation-mark gap, the server-name-label gap, the review record's lifetime and tombstone, and the new refusal classes in both Verification lists. Also records that a refusal resolving to no target keeps the wrapper bucket for ACP parameter-error loop accounting. Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> Patrol-Run: qwen-pr-closeout/jmuejxvnk09 * fix(core): tombstone the reviewed declaration on single-server re-discovery Two correctness fixes for code this branch added in its latest round, both verified red-first before the fix and pinned by a collocated test. R4-1: `invalidateReviewedDeclaration` was wired into `removeDiscoveredTools` and `removeMcpToolsByServer` but not into `discoverToolsForServer`, which hand-inlines the same removal. That method is the route `/mcp reconnect`, the MCP management dialogs and `DiscoveredMCPTool.attemptReconnect()` take, and the compensating `purgeServerRegistries` call iterates an already-emptied set, so nothing else writes the tombstone there. A replacement connection republishing a byte-identical declaration therefore replayed the pre-reconnect review instead of asking for a fresh one. Mirror the sibling site; keep the `DiscoveredMCPTool`/`serverName` filter and run before the re-registering `await`. R4-8: the `select:` dedupe key keyed unresolvable names on the canonicalized alias, so two distinct requested spellings that canonicalize to one alias (`task` and `agent`) collided on a single `seen` key. The second was dropped before the `maxResults` check and landed in none of missing/truncated/ ambiguous, silently shrinking the model-facing report (`Not found: task` / `1 missing` instead of `Not found: task, agent` / `2 missing`). Keep the resolved-identity key — that half is the case-variant fix — and key only the unresolved branch back on the requested spelling. Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> Patrol-Run: qwen-pr-closeout/jmuewsuay0r * refactor(core): drop the reviewed-declaration tombstone, gate on the record The tombstone existed so the review map could be pruned on removal without opening the never-reviewed pass-through. It did not hold: the record loop fingerprinted only tools hidden at render time, so a tool reviewed while revealed kept no entry, its removal wrote no tombstone, and a replacement publishing a changed contract was invoked with arguments the model wrote against the schema it actually saw. Remove the pruning rather than complete it. A retained entry can only match the same server, schema name and parameter schema, so it either still describes the live tool or forces a re-review, and no removal route has to remember to touch the map. Record every tool tool_search returns, not only the hidden ones, so reveal state no longer decides gate coverage. Answers round-5 R5-1 (ambiguous select: repeats had no witness) and R5-2 (the reveal-state hole); moots R4-1, R4-5 and R4-6, which were all properties of the tombstone. Design doc updated in both languages. Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> --------- Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

2. The model calls `tool_call` with the exact deferred tool name and arguments.
|
||||
|
||||
Both halves resolve a requested name the same way, so the schema `tool_search`
|
||||
returns is the tool `tool_call` invokes: a legacy alias is canonicalized first
|
||||
(`search_file_content` → `grep_search`, `replace` → `edit`, `task` → `agent`),
|
||||
then an exact registered match wins, then a single case-insensitive match
|
||||
resolves. A name that matches several registered tools only by case resolves to
|
||||
none of them — registration order decides nothing — and both halves refuse it:
|
||||
`tool_search` reports it as ambiguous and lists the spellings that do resolve,
|
||||
`tool_call` refuses and asks for the exact name. A tool that was never reviewed
|
||||
in this session still resolves by name.
|
||||
|
||||
When `tool_search` returns a tool, it records a fingerprint of that tool's
|
||||
invocation contract — its MCP server (empty for a built-in), the name in its
|
||||
schema, and its `parametersJsonSchema`. `tool_call` recomputes the fingerprint
|
||||
and refuses a hidden tool whose live value differs, telling the model to re-run
|
||||
`tool_search` with `select:<name>`. A re-review overwrites the record, so that
|
||||
loop closes in one round trip. Recording is not gated on whether the tool is
|
||||
hidden at review time: a revealed tool can be hidden again later, and gating
|
||||
the record on reveal state would make the comparison's coverage depend on state
|
||||
the model neither controls nor observes. The free-text `description` is not part
|
||||
of the fingerprint: shipped deferred tools rebuild it from mutable state on
|
||||
every `schema` access (`web_search` interpolates the current month, `read_file`
|
||||
the effective input modalities), so hashing that prose would refuse calls whose

parameters still match the reviewed schema.

|

|
||||
## Known limitations
|
||||
|
||||
`tool_call` routes a hidden deferred tool by name alone: it does not record a
|
||||
per-session presentation mark when `tool_search` delivers a schema, and it does
|
||||
not compare a captured schema fingerprint against the live schema at call time.
|
||||
A model can therefore invoke a hidden tool whose schema never entered the
|
||||
active model context (the startup reminder already lists every hidden deferred
|
||||
tool's name and description), or whose schema changed after a mid-session MCP
|
||||
re-discovery. V1 deliberately accepts this name-only authorization boundary.
|
||||
The presentation-mark and fingerprint precondition proposed in #6721 is
|
||||
deferred to #11321 rather than required by this bridge.
|
||||
`tool_call` records no per-session presentation mark. A hidden tool whose schema
|
||||
never entered the active model context is still invocable by name, because the
|
||||
startup reminder already lists every hidden deferred tool's name and
|
||||
description, and only a tool `tool_search` returned in this session carries a
|
||||
fingerprint to compare against. The declaration check therefore narrows the
|
||||
name-only authorization boundary instead of closing it; the presentation-mark
|
||||
half of the precondition proposed in #6721 remains open in #11321.
|
||||
|
||||
A change limited to a tool's `description` is not detected, deliberately: those
|
||||
getters must keep recomputing so a long-lived process is not stale across a
|
||||
month boundary or a mid-session model switch.
|
||||
|
||||
The fingerprint's only server component is the server's name label, so a
|
||||
replacement server republishing identical tool names and schemas is accepted
|
||||
with arguments written against the previous connection. Telling a connection
|
||||
identity apart from a name label needs a channel the registry does not have
|
||||
today; it is tracked in the #11321 discussion rather than approximated here.
|
||||
|
||||
Review records live on the registry instance, survive `/clear`, and are never
|
||||
pruned. An entry can only match the same server, schema name and parameter
|
||||
schema, so a stale one either still describes the live tool or makes `tool_call`
|
||||
ask for a fresh review. Pruning on removal would invert that: a dropped entry
|
||||
reads as "never reviewed" and passes a replacement through. The map is bounded
|
||||
by the distinct tool names reviewed in the process.

`tool_call` 仅按名称路由隐藏的延迟工具：它不会在 `tool_search` 发送 schema 时
|
||||
记录每会话的呈现标记，也不会在调用时比较已发送的 schema 指纹与当前 schema。
|
||||

`tool_call` 不记录每会话的呈现标记。schema 从未进入活跃模型上下文的隐藏工具仍可
|

按名称调用：启动提醒已经列出全部隐藏延迟工具的名称和说明，而只有本会话中
|
||||
`tool_search` 返回过的工具才有可比对的指纹。因此声明比对收窄了“仅按名称授权”的
|

边界，而没有关闭它；#6721 提出的前置条件中，呈现标记那一半仍在 #11321 中跟踪。
|
||||

||||
仅涉及 `description` 的变化不会被检测到，这是有意为之：这些 getter 必须继续按
|
||||
当前状态重算，长驻进程才不会跨月或跨会话内切换模型后使用过期文案。
|
||||
|
||||
指纹中唯一的服务端成分是 server 的名称标签，因此一个以相同工具名和 schema 重新
|
||||
发布的替代 server 会被接受，而参数是针对上一次连接写的。要把连接身份与名称标签

审阅记录挂在 registry 实例上、跨 `/clear` 保留，且从不清理。一个条目只可能匹配
