Prompt: Add tracking of all LLM HTTP requests to a database table
(llm_requests) for debugging/auditing, plus add custom headers
(User-Agent with Shelley version, Shelley-ConversationId) to all
outgoing LLM requests. Remove existing HTTPRecorder callback and ant's
DumpLLM; we don't need them. Remove in-memory LLMRequestHistory and
/debug/llm endpoint. Make sure that the anthropic and openai and gemini
implementations all follow the same pattern/implementation here.

- Add llm_requests table for tracking/debugging LLM API calls
- Add custom HTTP headers: User-Agent with Shelley version, Shelley-ConversationId
- Create llmhttp package for HTTP transport with recording and headers
- Remove HTTPRecorder callback from ant.Service
- Remove DumpLLM from ant, oai, and gem services
- Remove in-memory LLMRequestHistory and /debug/llm endpoint
- Update models.Manager to use new database-based recording
- Pass http.Client through factory functions for consistent transport

The llm_requests table stores:
- conversation_id (optional)
- model and provider
- URL, request/response bodies
- status code, error, duration

Custom headers help with debugging and tracing:
- User-Agent: Shelley/<commit_hash>
- Shelley-ConversationId: <conversation_id>

Prompt: fix https://github.com/boldsoftware/shelley/issues/30

Fix issue where the system prompt was generated before loading the cwd
from the conversation record, causing it to use the server's working
directory instead of the user's specified context directory.

The cwd is now loaded from the conversation before generating the

We'll see if this sticks and is found useful. You can't really
have the LLM output HTML, because it ends up dangerous in the timeline.
But you can embed an iframe. So let's give the LLM a way to do that!

Prompt: I want Shelley to be able to produce HTML output that the user
can see, but for security, I want this to be made safe by using an
iframe. For example, if I ask Shelley to produce a vegalite
visualization, I want the agent to be able to produce sandboxed HTML to
do that. Create a new tool "output_iframe" that should be used for
visual elements if the agent wants to display them, and should be
expanded by default in the HTML tool output. Advise the tool description
to only use this for visualizations like graphs and demonstrations of
HTML, and to use regular messages for chatting with the user.

Add a new tool 'output_iframe' that allows the agent to display HTML content
to the user in a secure sandboxed iframe. This is useful for:
- Vega-Lite and other chart library visualizations
- HTML/CSS demonstrations
- Interactive widgets
- SVG graphics

The tool:
- Takes HTML content and optional title as input
- Returns 'displayed' to the LLM (minimal response)
- Passes HTML to UI via Display field for rendering
- Uses sandbox="allow-scripts" for security (scripts run but can't access parent)

The UI component:
- Renders iframe with srcdoc for the HTML
- Expanded by default (like screenshot tool)
- Styled consistently with other tool components

Tool description explicitly advises using this only for visualizations,
not for regular chat messages.

Prompt: we're continuing work in this worktree (don't switch) on subagents. I think things are working. Can you tell me what the system prmopt is for subagents? Is it the same as the main one? how does that end up working?

Prompt: 1. Fetch and rebase on origin/main. Notably, there's a UI change to indicate which conversations are working vs. not, and that might need to be plumbed into subagent tasks in the convo list. 2. Let's write a system prompt for subagents. It should be short, but include some of the basic details. It's important to understand that only the last message gets sent to the parent agent, though it can of course reference files and so on.

Prompt: fetch, rebase on origin/main, and squash into one commit

Adds a subagent tool that allows the main agent to spawn independent
conversations for parallel task delegation. Subagents:
- Have their own conversation with full tool access (except nested subagents)
- Run with a minimal system prompt focused on task completion
- Return their final message to the parent agent
- Support both synchronous (wait) and async (fire-and-forget) modes

Key changes:
- New subagent tool in claudetool/subagent.go
- SubagentRunner in server/subagent.go handles conversation lifecycle
- Database schema adds parent_conversation_id for tracking hierarchy
- Minimal subagent system prompt (vs full 17KB main prompt)
- UI shows subagents nested under parent conversations
- Working indicator (pulsing dot) for subagent conversations

Prompt: Let's separate the concept of "agent working" from interpreting the message stream to figure out the state and let's be explicit. The server knows whether it is doing stuff (like tool calls or LLM calls). Let's say that we have a special type of message that's always sent whenever there are updates to indicate the "agent is working" state explicitly. Get rid of is working on the existing struct.

Follow-ups:
- Git working status isn't connected to end of turn; we can just focus on whether or not we're in the agent loop or not. Test the case where a conversation is loaded after a server restart; the agent isn't working in that case because the conversation isn't loaded. Make this a ConversationState object instead of an AgentStatus object because it's per conversation. These should be broadcast because a user might care about their other conversations too
- Add a little indicator dot for conversations that are in the working state. This also implies listing conversations requires exposing this state.

Instead of inferring the agent working state from the message stream
on the client side, have the server explicitly track and broadcast
the state via a new ConversationState struct.

Server changes:
- Add ConversationState struct with ConversationID and Working fields
- Add ConversationWithState for list endpoint (Conversation + working)
- Add SetAgentWorking/IsAgentWorking methods to ConversationManager
- Broadcast ConversationState changes to ALL active conversation managers
- Set working=true when AcceptUserMessage queues work
- Set working=false when agent message with end_of_turn=true is recorded
- Set working=false on conversation cancel
- Update /api/conversations to include working state
- Add test verifying Working=false after server restart (no active loop)
- Remove agentWorking() inference function and its tests

UI changes:
- Add pulsing blue dot indicator next to working conversations in drawer
- Handle conversation_state updates from stream to update working state
- Preserve working state when receiving ConversationListUpdate messages

Prompt: Handle https://github.com/boldsoftware/shelley/issues/7 - support browser downloads and write large outputs to files.

---

Add support for browser-initiated file downloads and improve handling of
large tool outputs.

**Downloads:**
- Browser now saves downloaded files to /tmp/shelley-downloads/ with
  randomized filenames (e.g., filename_abc12345.ext)
- Downloads are reported in navigate/eval tool output with filename,
  source URL, and save path
- Navigation to download URLs (like direct PDF links) now reports
  success with download info instead of ERR_ABORTED error

**Large output handling:**
- Console logs (browser_recent_console_logs) exceeding 1KB are written
  to /tmp/shelley-console-logs/ and the tool returns the file path
- JavaScript results (browser_eval) exceeding 1KB are similarly written
  to files instead of returned inline

Example output for downloads:
  Navigation triggered download(s):
    - report.pdf (from https://example.com/report.pdf) saved to: /tmp/shelley-downloads/report_a1b2c3d4.pdf

Example output for large JS results:
  JavaScript result (5000 bytes) written to: /tmp/shelley-console-logs/js_result_x1y2z3.json

Prompt: Get rid of the right click menu for copy and paste. Instead if
you tap on a message, a copy icon should show up above the message that
can be clicked. Likewise an info icon for usage details. This should
work for tool results as well.

Replace the context menu (right-click/long-press) with a tap-to-show
action bar for copy and usage info actions. When a message is tapped,
a small action bar appears in the top-right corner of the message with:

- Copy icon: copies message text (including tool results) to clipboard
- Info icon: shows usage details modal (only for agent messages)

The action bar:
- Appears on tap/click anywhere on the message
- Closes when clicking outside the message
- Works for all message types including tool results
- Shows feedback (checkmark) after successful copy

This provides a more touch-friendly UX compared to the context menu,
and the icons are always accessible without needing to know about
right-click or long-press gestures.

Prompt: When shelley shows a screenshot, it takes up the whole width,

Add width: fit-content to .screenshot-tool-image-container so it shrinks
to the image's natural size. The max-width: 100% ensures it still doesn't

phil: Don't love the impl here, but not having cancel was really
crimping my style. The whole agent_working status thing has been
really error prone.

Prompt: I'm not seeing Shelley show 'Agent is working...' any more. I
suspect the change that dealt with reconnects may have broken it? Follow
up: I think the issue is that messages from other conversations updating
the conversation name or whatever are confusing the logic.

The agent_working field in StreamResponse was being set to false (the zero
value) when sending conversation metadata updates (like slug changes). This
caused the UI to incorrectly clear the 'Agent working...' status immediately
after the agent started working.

Fix by changing AgentWorking from bool to *bool with omitempty, so metadata-
only updates don't include the field at all. The UI already checks
typeof agent_working === 'boolean' before updating state, so undefined
values are correctly ignored.

- Change StreamResponse.AgentWorking from bool to *bool with omitempty
- Update agentWorking() to return *bool
- Add boolPtr() helper function
- Update tests to handle pointer comparisons
- Regenerate TypeScript types

Prompt: When two conversations are running at the same time, the updates to each other's status (last updated, probably) makes them resort, and it's very distracting, especially if they compete with each other. Let's just not resort them

When two conversations run simultaneously, updates cause them to
compete for position, which is visually distracting. Now we update
conversations in place and only put new conversations at the top.

Co-authored-by: Shelley <shelley@exe.dev>

Prompt: This test is flaky. [...] I think the issue is that slug updates aren't messages. I think we send conversation updates (see 3dbcb107dbbb6753c7af811d535b559c794a674b) over the same stream but without message ids. Fix it. Run the test a lot to make sure it's not flaky.

notifySubscribers (for metadata like slug changes) was using Publish with
sequence IDs, which could race with notifySubscribersNewMessage. If the
metadata update ran first, it would consume the sequence slot and the actual
message would be skipped. Changed notifySubscribers to use Broadcast instead,
which doesn't interfere with message sequence tracking.

Prompt: the conversations list doesn't update as different conversations update. We should send messages to /stream to update the conversation list appropriately when things about conversations change. Be sure to test it with the relevant test harness.
Follow-up: fetch & rebase on origin/main. I don't want to have to open multiple connections; we already have a /stream connection. I think the invariant is that the client is subscribed to one stream at a time; let's send conversation updates over the same stream!

Instead of creating a separate SSE endpoint, send conversation list updates
through the existing per-conversation stream at /api/conversation/{id}/stream.

Changes:
- Add Broadcast() method to SubPub to send messages to all subscribers
  regardless of sequence ID (for out-of-band notifications)
- Add ConversationListUpdate field to StreamResponse
- publishConversationListUpdate broadcasts to ALL active conversation managers
- Server publishes updates when:
  - New conversation is created
  - Conversation is archived/unarchived
  - Conversation is deleted
  - Conversation is renamed
  - Conversation gets a new message (updated_at changes)
  - Conversation slug is generated asynchronously
- UI ChatInterface receives updates and passes to App via onConversationListUpdate
- App updates conversation list in real-time without separate connection

Prompt: fix and add a test for the following new Shelley inline diff view causes the page to break in Firefox; it goes completely blank and then I get this error:
Error: ModelService: Cannot add model because it already exists!

The inline diff view in PatchTool was crashing Firefox with 'Cannot add
model because it already exists!' when collapsing and expanding the diff.

Root cause: Monaco editor models were created but never disposed during
cleanup. When the component unmounted and remounted (or the useEffect
re-ran), new models were created with potentially conflicting URIs.

Fix:
- Track Monaco models in a ref (modelsRef)
- Dispose models in the cleanup function alongside the editor
- Defensively check for and dispose existing models before creating new
  ones (in case of timing issues)

Also added:
- 'patch success' command to predictable model (uses overwrite operation)
- E2E test that verifies collapse/expand cycles don't cause errors
