+ # The block renders each parameter's TYPE but not its prose — the host keeps the description off the prompt because a real catalogue carries ~6.8 KB of it, re-sent every turn for the one parameter a cell touches. It lands here instead, where `read?` reaches it and where the block already sends the model for a tool's own description.

**issue (broader_impact)：** 当某个单元格通过 `from __dsh__.tools import read` 导入工具后，架构发生修订时，重新绑定会替换 `__dsh__.tools` 中的函数，但不会更新 shell 命名空间中现有的 `read` 名称。因此，`read?` 会继续显示旧的参数描述，所声称的架构修订刷新无法传达到通常的导入绑定。
**触发条件：** 在 MCP 重新连接或架构修订更改某个参数描述之前，工具已被导入。
**建议修复：** 在重新绑定时更新或使现有 shell 别名失效，或者明确说明调用方必须在架构发生变化后重新导入工具。

</code_context>
<issue_to_address>
**issue (broader_impact):** When a schema is revised after a cell has imported a tool with `from __dsh__.tools import read`, rebinding replaces the function in `__dsh__.tools` but does not update the existing `read` name in the shell namespace. `read?` therefore continues showing the old parameter description, so the claimed revised-schema refresh does not reach the normal imported binding.
**Triggers:** When a tool is imported before an MCP reconnect or schema revision changes one of its parameter descriptions.
**Suggested fix:** Update or invalidate existing shell aliases when rebinding, or explicitly document that callers must re-import tools after a schema change.

A parameter's type is not what it means.
queriesislist[str]either way; only the prose says 1–4 of them. Native tool calling ships that prose in every request'stools[]array — we shipped none of it:toolSpecprojected each parameter to{name, type, required}and droppeddescriptionat the host, and the tool's own description survived only as the function's__doc__. So the block showed types and nothing else.This carries both, in the shape a Python reader expects — one parameter per line with its description as a trailing comment, the tool's own as a docstring:
MCP tools keep their comment form, since only
mcpis bound at the top level, and are commented line by line:The same prose also reaches
read?as aParameters:section, so the runtime view is not the poorer of the two — same source, so they cannot drift.dsh-py-codeact/lib/index.js
Lines 305 to 327 in ea5cbc1
What it costs
The block is re-read every turn, so the number matters. Measured on the live headless catalogue, 33 tools:
For comparison, dsh's own Code Mode renders the same catalogue at 44446 characters with descriptions and 24569 without, so this is in line with the harness's own choice rather than an outlier. Either half can be dropped on its own if the trade is not worth it — they are independent, one line each.
Two ways prose breaks a program
Prose in the block is no longer content, it is syntax, and both hazards are guarded and tested.
A
#comment cannot span lines, so a description carrying newlines is collapsed onto one line; emitted as-is its second line parses as code. And a description containing"""or ending in a backslash would close its own docstring and take every tool below it down — the failure class #12 was, where one tool invalidates the whole block. Neither shape appears in a live catalogue; a future MCP server is not bound by that, so both are escaped rather than trusted.The
typingimport is now derived from the type expressions the render actually spells, kept separately from the lines, rather than by regex over the emitted text. With prose in those lines, a description mentioning "Any file" would otherwise importAny.Verification
Six assertions added or rewritten, 115 total, all pass. Each mutation-checked by reverting the exact line it guards:
Parameters:sectioneach description lands under the parameter it belongs todocthe host is what puts it there, straight off the schemaa triple quote or trailing backslash costs fidelity, never the blockand the block carries it too, beside the parameter and as the docstringNote
Two gaps the mutation check found, neither visible from a green suite. First, the kernel test built its specs by hand, so removing
doc: node?.descriptionfrom the host changed nothing. Second, no fixture carried a parameter description with a newline in it, so the collapsing was unguarded —the rendered block is a programdid not catch it either, because its fixture has no prose. Both assertions exist because of that, not alongside it.One earlier assertion was inverted, not fixed:
and none of it reaches the block the model reads every turnguarded the opposite contract, when the descriptions were deliberately kept off the prompt. That decision was reversed here, so the guard now asserts they arrive, attributed to the right parameter and in the right shape.Warning
A rebind builds new callables, so a name already pulled out with
from __dsh__.tools import readkeeps the docstring it was imported with — raised by Sourcery, reproduced, and true of the signature and return annotation too, ever since bindings existed.__dsh__.tools.read?is the authoritative view after a schema revision. Not changed here: refreshing would mean a rebind reaching into the model's own namespace, the very hazard_handleis written around.Gates:
node test/smoke.js,uvx ruff check py/,TY_UV=scripts uvx ty check py/kernel.py— all clean. README updated where it said the block carries signatures only.
