Moves create_session, list_sessions, send_to_session and manage_session out of
ai_interaction.py into src/agent_tools/session_tools.py (the do_ prefix
dropped) and registers them in TOOL_HANDLERS, so dispatch flows through the
registry instead of the dispatch_ai_tool elif in tool_execution.py. Same
pattern as the model-interaction move.
The bodies move verbatim; each fetches the runtime-set session manager via a
get_session_manager() shim, and reuses _resolve_model / AI_CHAT_TIMEOUT from
ai_interaction. manage_session's internal 'list' alias is repointed from the
old do_list_sessions to the moved list_sessions. stream_ai_tool (dead, no
callers) and do_pipeline stay put. dispatch_ai_tool loses its four now-unused
branches.
Tests: test_session_tools_registry covers registration, owner threading, the
manage_session->list_sessions delegation, graceful no-manager handling, and
registry dispatch. Verified end-to-end against a live SessionManager.
Detached bash jobs (#!bg) could be launched and auto-reported on completion,
but the agent had no way to act on a running one: no on-demand output read and
no kill (it blocked until the 1h max-runtime). bg_jobs had the pieces
(_read_output, list_for_session, internal _kill) but none was exposed.
Adds:
- bg_jobs.kill(job_id): tears down the process tree, marks the job killed, and
sets followed_up so the monitor does not also auto-continue a deliberate kill.
- manage_bg_jobs registry tool with actions list / output / kill, scoped to the
chat that launched the job (cross-session access reads as not found).
- Wiring: TOOL_HANDLERS/TAGS, function schema, RAG index + keyword hints, parser
name map, dispatch (threads session_id via _direct_fallback). Gated like bash
(NON_ADMIN_BLOCKED_TOOLS; plan-mode mutator).
- agent_loop: background-job intent regex maps to the files domain (and the tool
joins _DOMAIN_TOOL_MAP[files]) so short commands like 'kill that job' are not
dropped by the low-signal gate that skips tool retrieval.
- bg launch message tells the model to call manage_bg_jobs itself for check/stop
rather than printing raw tool syntax to the user.
Tests: tests/test_bg_job_tools.py (kill semantics, per-chat scoping, actions,
and the intent classifier).
* fix(tools): prune skipped dirs before descending in glob tool
GlobTool used pathlib.Path.rglob which descends into every directory
(including node_modules, .git, dist, etc.) and filters AFTER the walk.
On repos with large junk directories this causes the glob tool to hang
for minutes.
Replace rglob with os.walk that prunes _CODENAV_SKIP_DIRS before
descending — matching the approach GrepTool already uses. Also add a
fast path for literal patterns (no wildcards → direct path lookup).
Fixes#4493
* fix(tools): use regex glob matching to fix * semantics and literal fallback
Replace fnmatch with _glob_to_regex so that * stays within a single
path segment (matching pathlib/rglob semantics) and **/ spans zero or
more directories. Literal patterns now fall through to os.walk when
the direct path lookup misses, so e.g. 'foo.py' still finds files at
any depth.
Add tests for:
- bare literal matching in subdirectories
- multi-segment single-star patterns (sub/*.txt)
- * not crossing / boundaries
- ** matching at arbitrary depth
Closes#4493

Moves chat_with_model, ask_teacher and list_models out of ai_interaction.py
into src/agent_tools/model_interaction_tools.py (the do_ prefix dropped) and
registers them in TOOL_HANDLERS, so dispatch flows through the registry instead
of the dispatch_ai_tool elif in tool_execution.py.
The implementations are relocated, not wrapped. ai_interaction.py keeps only
the shared helpers they reuse (_resolve_model, AI_CHAT_TIMEOUT), still used by
the not-yet-migrated session/pipeline tools. dispatch_ai_tool loses its three
now-unused branches.
Also removes the dead do_second_opinion: it was already off the live tool
surface (no tag/schema/parsing/dispatch; tool_index.py notes it was removed),
so the function and its stale frontend catalog entries (admin.js, assistant.js)
are deleted.
Tests: owner-scope test points at the new list_models location and drops the
moved tools from the dispatch_ai_tool parametrize; a new
test_model_interaction_registry covers registration, owner threading, and
registry dispatch.
* fix(search): add download budgets to web_fetch with truncation notice and hard ceiling
MAX_OUTPUT_CHARS only trims what the agent sees; fetch_webpage_content
buffered and cached the entire response body first, so a large or hostile
URL could pull arbitrarily many bytes into memory and the content cache.
The fetch is now a capped streaming GET (SSRF redirect guard unchanged):
a soft default budget (WEB_FETCH_SOFT_MAX_BYTES, 2 MB), a per-call
override via full/max_bytes on the web_fetch tool, and a hard ceiling
(WEB_FETCH_HARD_MAX_BYTES, 20 MB) that the override can never exceed.
When Content-Length already declares a body over the ceiling the fetch
is refused before any body bytes are buffered. Truncated results carry
truncated/fetched_bytes/total_bytes, the tool output leads with a
partial-content notice telling the model how to re-fetch with full=true,
and the tool schema documents the flag. A truncated PDF is reported as
a budget error since a cut PDF is unparseable. The effective cap is part
of the content-cache key so a truncated fetch is never served to a
full-budget request.
Existing tests that faked httpx.get or the old _get_public_url signature
are adapted to the streaming interface; behavior pins are unchanged.
Fixes#3812
* fix(search): close compressed-body cap bypass and protect the partial notice
Addresses RaresKeY's review on #3955:
- Force Accept-Encoding: identity for the capped fetch. With gzip/deflate the
wire bytes (and Content-Length) can be a fraction of the decoded body, so a
tiny compressed response could pass the hard-cap preflight and then expand
past the ceiling in a single decoded chunk before the streamed cap could
slice it. Identity makes Content-Length the true body size and keeps each
streamed chunk bounded by the network read, so the hard ceiling actually
bounds memory.
- Lead web_fetch output with the partial-content notice and cap the page
title. The notice is the user-facing contract for partial fetches, but the
title is untrusted, uncapped page content; placed ahead of the notice a giant
title could push it past MAX_OUTPUT_CHARS and drop it. The notice now leads
and the title is capped as a second guard.
Adds regressions: the fetch advertises identity encoding, and a truncated
result with an oversized title still surfaces the partial notice.
* fix(search): reject compressed responses that ignore the identity request
Requesting Accept-Encoding: identity is not enough on its own: a server can
ignore it and still return Content-Encoding: gzip, and httpx.iter_bytes would
decode that, so a tiny compressed body could balloon into one decoded chunk
far past the hard cap before the streamed loop slices it (and Content-Length,
the compressed wire length, makes the preflight and size metadata unreliable).
Refuse a non-identity Content-Encoding before reading the body. Adds a
regression where the server ignores the identity request and returns gzip;
the fetch is refused before any body is decoded.
* feat(agent): workspace confinement via context-local binding + get_workspace tool
Bind the per-turn workspace once in execute_tool_block; the shared path
resolvers (_resolve_tool_path / _resolve_search_root) and the subprocess cwd
helper (agent_cwd) read it, so file tools + bash/python are confined centrally
and a new tool that uses the shared helpers cannot accidentally bypass it.
Adds the admin-gated /api/workspace/browse picker, a workspace pill + directory
modal (reusing existing modal/button CSS), the /workspace slash command, and a
get_workspace tool (replaces a system-prompt block). Confinement is OS-agnostic
(realpath/normcase/commonpath) and docker-safe (container paths, no host
assumptions). Reopens#2023.
* ux(workspace): clarify workspace is not a sandbox
Picker modal note + pill tooltip + get_workspace tool/output wording now state
plainly: read_file/write_file/edit_file/grep/glob/ls are confined to the folder,
but bash/python only start there (cwd) and are not sandboxed. Modal note reuses
the existing .muted class.
* fix(agent): treat an active workspace as file-work intent
A vague low-signal message (e.g. "look at the local project") matches no
domain keywords, so tool retrieval is skipped and only always-available tools
are offered — leaving the agent with no file access even though a workspace is
set. When a workspace is active, include the file/code tools (incl.
get_workspace) on low-signal turns so the agent can act on the folder.
Also requires the tool index (ChromaDB) to be reachable for normal retrieval;
that is an environment dependency, not part of this change.
* ux(workspace): hide pill + overflow entry in chat mode
Workspace only scopes the agent's file/shell tools, so the pill and the
overflow 'Workspace' entry are agent-only now — hidden in chat mode like the
bash toggle. Mode read from the DOM in syncWorkspaceIndicator; applyMode() is
called from the agent/chat setMode handler.
* prompt(tools): steer bash/python to defer to the dedicated file tools
bash/python schema descriptions (what native-tool-calling models read) were
bare and gave no steer, so models would do file ops via the shell (e.g. writing
SVG/HTML, which then dumps raw markup into the tool preview). Tell bash/python
in the schema + tool-index + prompt section to prefer read_file/write_file/
edit_file/grep/glob/ls and only be used for what those do not cover.
* prompt(tools): keep bash/python deferral generic (no hardcoded tool names)
Reference 'a dedicated tool' rather than listing read_file/write_file/grep/etc.
by name, so the guidance does not go stale if those tools are renamed.
* style(workspace): drop em-dashes from added code comments/strings
* ux(workspace): terser non-sandbox note in picker (no tool-name list)
* ux(workspace): mirror terse non-sandbox wording in pill tooltip
* chore: untrack local venv symlink (run-only, not part of the feature)
* prompt(workspace): keep get_workspace text generic (no hardcoded tool names)
* fix(agent): low-signal + workspace surfaces only read-only file tools
Intersect the files tool group with PLAN_MODE_READONLY_TOOLS so a vague message
in a workspace exposes read_file/grep/glob/ls/get_workspace for exploration, but
not write_file/edit_file/bash/python -- those wait for a request that actually
calls for them (RAG retrieval still adds them on a real ask).
* feat(workspace): cap browse listing at 500 dirs with a truncated hint
Mirror the filesystem_tools._CODENAV_MAX_HITS pattern with a module-local
_MAX_BROWSE_DIRS so a directory with thousands of children does not dump every
row into the picker; the response carries a truncated flag and the modal tells
the user to type a path to jump in.
* chore: untrack local venv symlink (run-only artifact)
* fix(workspace): vet the workspace root against the sensitive-path deny list at bind time
The in-workspace resolver deny-lists sensitive paths inside the workspace,
but the empty-path search root is the workspace itself, so a workspace of
~/.ssh could be listed via ls with no path. vet_workspace() (public, in
tool_execution next to the resolvers) rejects non-directories and sensitive
roots before the path is ever bound; chat_routes uses it instead of its
inline isdir check.
* fix(workspace): reject filesystem roots and stop showing rejected workspaces as active
Review findings from #3665:
P2: vet_workspace accepted / (and would accept drive/UNC roots), which makes
every absolute path 'inside' the workspace and collapses confinement into
host-wide file access. A root is its own dirname, so reject when
dirname(resolved) == resolved; the browse response now carries a selectable
flag and the picker disables 'Use this folder' on unselectable dirs.
P3: /workspace set stored any string client-side and the chat route silently
dropped rejected values, so the pill could claim a confinement that was not
in effect. New admin-gated /api/workspace/vet validates manual paths before
they persist (canonical path returned), and when a posted workspace is
rejected at send time the stream emits workspace_rejected so the client
clears the stored value and toasts instead of continuing silently.
* fix(workspace): check caller privilege before vetting the posted workspace
Review finding: /api/chat_stream called vet_workspace() on the posted value
for every caller and emitted workspace_rejected on failure, so a non-admin
who can chat but cannot use file/shell tools could distinguish existing
directories from missing/file/sensitive/root paths by whether the event
appeared. The resolution now lives in _resolve_request_workspace, which
drops the submitted value uniformly for non-admin callers, with no vetting
and no event, before the path ever touches the filesystem. Admin and
single-user behavior is unchanged. Test pins that valid and invalid paths
are indistinguishable for a non-admin and that vet_workspace is never
invoked for them.
* refactor(tools): implement strict cohesive class coordinator pattern per #2917
* test: update edit_file tests to use EditFileTool class
* fix(tools): restore tool_policy param and security backstop in coordinator
* refactor(tools): migrate domain tools to agent_tools package per #2917
* test: update test imports for new agent_tools package
* fix: resolve circular import between tool_execution and agent_tools
* fix: remove leftover git conflict markers
* fix(tools): resolve pytest failure and document _apply method
* fix(tools): clean up whitespace and remove dead _tool_python helper
