`provider_blocks` means something only to the surface that produced them (Anthropic `thinking` / server-tool blocks). A session that switched surface would otherwise send those dicts to a chat-completions provider as an assistant-message key it does not know; the request normalization drops the field, on a copy, so the history keeps it.
Streaming is the default path: `thinking` fragments, a `server_tool_use`'s `partial_json` query and a `web_search_tool_result`'s entries arrive as separate SSE events, so the blocks the round has to hand back exist only as fragments. The dispatch rebuilds each one from its start payload (field for field, under the stream's own names) plus the fragments that follow, and passes it to the loop as a chunk; the loop copies it onto the round's message, where a round that kept only those blocks counts as payload rather than an empty completion.
The thinking text streams as reasoning as it arrives — the search query and the signature go back with the round only.
DeepSeek's Anthropic compat answers a hosted search inside the turn: the response carries the `thinking` that picked the query, the `server_tool_use`, and the `web_search_tool_result`. The response mapping kept text and tool_use only, so the round lost its evidence — and the `thinking` signature, which only the provider can verify, could not go back at all. `AssistantChatMessage.provider_blocks` carries those blocks as raw JSON now (`thinking` text *and* signature, the query, the result entries with an `encrypted_content` the API rejects when trimmed) and the assistant turn hands them back first, ahead of its text and tool_use blocks; `thinking` also lands in `reasoning_content`, so the chain of thought streams as reasoning like every other surface's.
`AnthropicRawContentBlock` names the provider fields a streamed block carries, and `AnthropicServerToolUseContent` keeps the `caller` metadata the wire sends.
DeepSeek's Responses stream sends ``response.reasoning_text.delta`` fragments and then ``response.reasoning_text.done`` carrying the whole chain of thought those fragments spelled out. The loop folded a full delta into the round — it replaces the fragments, and that is what the assistant message hands back to the API — but streamed every delta verbatim, so the chain of thought was printed twice: once as it arrived and again as the ``.done`` text.
A full delta now streams only a tail the fragments did not cover, and nothing at all when it merely repeats them; a round whose fragments never arrived still streams the full text once. The message keeps the complete text either way.
``web_search`` is composed by the CLI host rather than the builtin catalog, so it had no ``_PRETTY_LINES`` entry and fell back to the ``[tool] …`` / ``[tool ok] …`` whole lines. It now leads with ``* Web Search '<query>' `` (the query as a 60-character preview, like the ask and skill subjects) and lands on the hit count — or on ``(no results)`` when every source came up empty, an emptiness the tool reports as ``error: the search found nothing`` and which is therefore not shown as a failure. A real error still prints in red with its message.
The guard test that keeps a builtin tool from shipping without a renderer now checks this host-composed tool too, since a catalog walk cannot see it.
``search_sources`` (a provider list, ``["deepseek", "bing"]`` by default,
``[]`` to not offer the tool at all) names what the local ``web_search`` tool
searches with, in fallback order: ``search_in_order`` asks each source in turn
and keeps the first answer, so a source that errors — a rate limit, a rejected
key — or finds nothing hands over to the next instead of failing the tool. The
handler reports the failures only when every source came up empty.
The Bing leg answers with its RSS results (``?format=rss``), which need no key
and carry a description — the snippet DeepSeek's own index does not hand out —
and it goes through the ``fetch`` client, so the SSRF and host-grant policy
applies to it too (a host that binds tool instance state, as the CLI does).
``provider_tools`` reached the effective provider only for the OpenAI preset,
so a DeepSeek ``provider_tools`` in TOML was dropped on the way — and the preset
defaulted to none, leaving search unavailable for every convention.
DeepSeek now defaults to ``[{type="web_search"}]`` like OpenAI does (``[]``
turns it off) and its list reaches the agent: the Anthropic convention runs the
hosted search inside the response, the Responses and chat conventions get the
local ``web_search`` tool (see ``config.routing.local_web_search``).
Only DeepSeek's Anthropic-compatible surface runs a hosted ``web_search``: the
Responses and chat-completions surfaces answer "I can't browse the web" with
``{"type": "web_search"}`` and with the server-tool shape alike, so a DeepSeek
provider that talks them had no search at all.
``config.routing.local_web_search`` decides per provider: a DeepSeek provider
whose ``provider_tools`` ask for ``web_search`` and whose convention is not
``anthropic`` gets the local tool (``tools/net/search.py``), which asks the
search-capable endpoint behind the scenes and hands the model one ``title —
url`` line per hit — read a page with ``fetch``, the bodies stay server-side.
DeepSeek's preset asks for no hosted tool by default, so this stays opt-in.
DeepSeek runs ``web_search`` inside a turn — the request declares the server
tool, the response carries a ``server_tool_use`` per query and the
``web_search_tool_result`` it produced — so a search is one ``/messages`` call
whose hits are read out of the content blocks. The turn stops as soon as it has
searched (a live probe with 64 output tokens spent all of them before the search
and returned nothing, 512 answers with the hits).
Hits carry a title, a URL and an ``encrypted_content`` only the index can read,
so the hit list is all a caller gets: the page bodies stay server-side.
The compat opens with the question alone (``message_start`` reports 165 tokens)
and puts what the search then pulled in on ``message_delta`` (12468); merging
preferred the earlier value, so the CLI's context gauge and the auto-compact
threshold ran ~12k short of the request. The larger of the two wins now (output
tokens are the delta's cumulative count either way).
``omit_defaults`` dropped the block's defaulted discriminator, and a request
that carried thinking was answered with 422 "thinking: missing field ``type``" —
which is what the compat sent for any configured ``reasoning_effort``. The field
has no default now, so it always encodes (both call sites pass it).
DeepSeek's Anthropic compat runs a hosted ``web_search`` itself and answers with
the blocks that search produced — ``thinking``, ``server_tool_use`` (the query)
and ``web_search_tool_result`` — so the content union that knew only text and
tool_use could not decode a live search turn. It carries them now, ``tools``
accepts the opaque server-tool dicts the surface declares, and
``web_search_tool_result.content`` stays loose on purpose: its
``web_search_result`` entries hold an ``encrypted_content`` the API demands back
unchanged (a trimmed result is answered with 422 "missing field
``encrypted_content``").
``provider_tools`` reached only the Responses surface, and the Anthropic one
wants its own definition of the same intent: a bare ``web_search`` becomes
``{type="web_search_20250305", name="web_search"}`` (the server tool Claude
declares and DeepSeek's compat reads, keeping a ``max_uses`` cap or any other
key), merged after the local function tools.
Such a tool is the server's: it streams ``input_json_delta`` fragments like a
call, and reading them as one asked the registry for a tool the server had
already run. Block types are now tracked, so only a ``tool_use`` block becomes a
tool call; the search blocks and ``thinking`` are skipped by the response
mapping (the answer the model wrote already used them) and never executed.
Thinking mode checks the field per round, not per call: an answer whose message
carried no `reasoning_content` came back 400 with the wording a call gets ("the
`reasoning_content` … must be passed back to the API"), while an empty string
satisfies the check. The injection now touches every assistant message instead
of only the ones carrying `tool_calls`.
A request carrying `tools` must return every round's chain-of-thought — "必须完整
回传 `reasoning_content` … 即使该轮模型未实际进行工具调用" — and the API merges a
`reasoning` item into the assistant message its round forms: a missing item and
an empty `reasoning_text` are both answered with "The `reasoning_text` in the
thinking mode must be passed back to the API". Each round now goes back as its
reasoning, its text, then its calls, with a blank line standing in when the
round kept none (a `rollback_tail` carrier, a forged todo call, the seed a
compacted session starts with) — never words of the bridge's own for a round
that may genuinely have reasoned nothing. A round's calls stay contiguous ahead
of their outputs: an interleaved batch reads as a second round without
reasoning and is rejected the same way, and an output recorded after another
item moves up beside its own call.
The reasoning is read back from the item's `content` parts, the only part the
API documents for `reasoning` items (`summary` and `encrypted_content` are not
supported).
A failed turn keeps the calls that already ran as a bare pairing carrier, and
clipping the chain-of-thought off that carrier sent the call back to the API
with no reasoning at all — thinking mode refuses a call whose reasoning never
came back. The carrier keeps the reasoning and drops only the text.
`env -S "rm -rf /"` ran a command nothing looked at: the option belongs to the
wrapper, so the scan skipped it and the denylist found no program to block while
the soft confirm had no interpreter to review. Collect those values — `env
-S`/`--split-string` and `su -c`/`--command`/`--session-command`, jammed
`--opt=value` and `-Svalue` forms included — and confirm the call the way an
interpreter's `-c` one-liner is confirmed, printing the text under its own
`env -S` label. Recursing into the text for a hard denylist is left out for now:
the review asks the human, who sees the command.
The wrapper option table listed flags as if they consumed the next token, so
the program behind them was skipped: `exec -c git -c init.defaultBranch=main
init` resolved to `init` and the policy denied it as a denylisted basename,
while `exec -c rm -rf /`, `command -p rm -rf /` and `command -v rm` hid `rm`
from the denylist completely and `exec -c python -c …` lost the interpreter
review. Drop the entries that take no value — `exec -c`/`-l`, the whole
`command` entry, `pkexec --disable-internal-agent`, `su -p`, and `xargs -e`
(its argument is optional, and the jammed form needs no entry) — so the
resolved program is the one that really runs.
A round that asked for several calls printed the first one as an abandoned
half-line: the next prefix closed the still-open row (a bare newline), the
result then printed whole and repeated that prefix, and the rest of the batch
was suppressed. The model edits files in batches, so the duplicate row showed
up there most. Queue the later prefixes instead: each one opens its own row
once the row before it has taken its detail, which keeps one finished row per
call in call order and leaves the bytes identical to the non-interactive path.
Only output that genuinely takes the line — a prompt box, streamed text, an
error — still ends the open prefix as its own line. The cursor is still never
moved.
DeepSeek dropped the `v4` prefix from its flash model, and the old id stays
valid only as a compatibility alias. Seed the default catalog with the current
name so a provider that omits `models` no longer offers a deprecated id, and
follow the rename in the wire fixtures and the minimal config template. An
explicit `deepseek-v4-flash` in TOML still passes through unchanged.
A round that updated its todo list printed one header plus a full stack
render per call, so the same list appeared several times. When a batch only
touches todo tools, print one `* Todo x<N>: Push, Update` line and the last
result, whose text already ends with the final stack. A batch holding any
other tool keeps the per-call lines, and a todo call never prints a prefix
at call time (it would dangle when the batch is merged).
A caller that goes away mid-batch (cancel, display error) left the results of
tools that had already run out of history, so the retry ran them again. Append
the collected results first, then emit the events.
A tool batch counted as committed only once every call had its result, so a
batch cut short was dropped whole and the retry ran tools that had already
had effects. Keep the calls that did report a result: their assistant row
stays as the pairing carrier (a request must answer every tool_calls id),
without the text of the unfinished turn, and the calls without a result are
absent so the retry re-issues them instead of assuming they ran. The kept
rows go to the store right away, and a failed rollback write is not allowed
to mask the failure being rolled back.
A reasoning trace was appended after the body it produced, which read as if the
answer had come first and the thinking had followed it. It now leads the row,
under its own `reasoning:` label with a blank line before the answer - the order
the live stream uses. The trace only prints where it already did: a turn's ends
(the default view) and -vv; previews stay silent.
A skill root can live inside the workspace (the project-scope .claude/skills),
and grep reports those hits relative to the workspace root while outside ones
come back absolute. The attribution only stripped an absolute skill prefix, so
an in-workspace root produced alpha/alpha/SKILL.md - and, worse, a path that no
longer started with the skill name when the root itself was the workspace.
Normalizing the hit to an absolute path before relativizing to the skill covers
both, and the hit line is now matched with a pattern instead of a colon split so
a Windows drive letter cannot split it wrongly.
Found by running the REPL against a workspace-local skill root; the tool tests
only covered roots outside the workspace, so they get that case now.
ReplState builds the store from [skills] against the current workspace and
publishes its roots as static read-only roots, so read_file/grep_files see a
skill directory while writing stays denied; the roots are rebuilt when the
workspace changes, since the project-scope directories hang off it. Discovered
skills are folded into the system prompt the way MCP instructions are, with the
catalog cap and its 'use skill_search' hint, and only when tools are on and
injection is not switched off; [skills].enabled = false drops the tools from the
registry entirely.
The write policy is installed with the CLI confirm: once, session, or no, timed
with a default of no and independent of YOLO, because a skill directory is not a
grant. A library host that installs no hook keeps the deny default. /skills
lists, searches, reads, and reloads; /status counts what was found.
skill_create writes a SKILL.md (name, description, body) plus whatever bundled
files the model lists, and skill_edit changes one file of an existing skill
either by literal replacement, by appending, or by rewriting it. Both resolve
every path inside the skill directory first, so a bad argument is answered
before anything is written and before the human is asked anything; a rewritten
SKILL.md is re-parsed so a skill that lost its description (or its frontmatter)
says so instead of failing quietly. The store is reloaded after a write, which
makes a new skill visible to the very next skill_list.
Writing is a host policy, not a directory-access grant: the denylist wins
first, then a session grant, then [skills].allow_write, then the host's confirm
hook — asked once per skill directory, so one answer covers its files. A host
without a hook denies, which keeps the library default safe; the confirm can
also answer 'session' to cover the rest of the chat.
skill_list shows what was discovered (name, source root, directory, description)
together with the copies a name collision shadowed and the notes from repaired
frontmatter, so a third-party skill never disappears quietly. skill_read
addresses a skill by name and defaults to its SKILL.md, reusing read_file for
ranges, line numbers, and the continuation token; a bundled file is resolved
inside the skill directory only, symlinks included. skill_search greps every
visible skill (or one) and rebases each hit on its skill, which makes a match
attributable without absolute paths.
Reads need no grant: the host registers the roots as static read-only roots on
the workspace policy, so read_file/grep_files see skill directories too while
write access stays denied — skill writes will go through their own confirm.
Grep used to drop every file outside the primary workspace root, which also hid
hits under a granted directory; those now come back as absolute paths.
