An agent event set its label to the SSH profile's name, so the transcript read
"homeserver · ls -la" -- naming the machine rather than the thing that was done.
Built-in tools set no label at all and fell back to the function name, so a
saved memory read "memory_add". The status line said "Running shell_run…" and
the approval card had its own hand-written wording. Four places, four answers,
nothing checking that any of them agreed.
services/tool_labels.py is the one table all of them read now. Bash, Read,
Write, List, Web search, Memory saved; an icon each, instead of everything
being the sparkle.
The precedence is inverted on purpose. Tool events are persisted in
Message.tool_calls_json, so every agent row already on disk carries the profile
name -- a resolver that preferred the stored value would fix nothing for any
transcript that already exists. So a name the table knows resolves from the
table, and a name it does not -- a custom HTTP tool, an MCP tool, whose labels
are per row and cannot be tabulated -- keeps its own. One rule, both cases
correct. The machine moves to `detail`, where "where this ran" belongs.
tool_label and tool_icon are Jinja globals because a message bubble is rendered
from four handlers, and a fifth thing each of them must remember to pass is a
fifth thing one of them will forget.

A row in custom_tools becomes a ToolDef like any built-in, offered beside
the thirteen. The registry had to stop being an import-time constant for
that: `resolve_tools` now returns the schemas *and* the runners together,
carried to the loop on the ToolContext.
That closes a hole on the way. `run_tool` looked names up in the global
REGISTRY with no reference to what had been offered, so a model naming a
tool its chat was gated out of -- a family switched off, a permission the
reader lacks -- had it run anyway. The resolved set is now authoritative.
Arguments come from a model, so an argument may fill a hole but never move
the target: the scheme and host of a URL template are literal, values are
escaped for where they land, and the origin is pinned afterwards. Every
redirect hop is checked the way services/fetch.py checks one, and the
secret is dropped if a hop leaves the origin it was issued for.
Also fixes the tool-activity block claiming every library tool had
"searched the web", which it has done since the second family landed.
