The invalid-params error paths already listed available agents,
but the unknown-agent path in runSingleAgent just returned
'Unknown agent: claude' with no hint what exists.
Now: 'Unknown agent: "claude". Available agents: "worker".'
Model would guess names like "claude", "default", or skill names
like "brave-search". Now it self-corrects on the next call.
Tested with Opus 4.6: without fix, model gave up on subagent
and ran the tool calls itself instead. With fix, 1 wasted call.
Demonstrates overriding built-in tool rendering to show only tool calls
in collapsed mode and full output in expanded mode. Shows how users can
implement a 'minimal mode' using the existing extension API.
- Add OSC 99 notification support for Kitty terminal (detected via KITTY_WINDOW_ID)
- Add Windows toast notifications for Windows Terminal/WSL (detected via WT_SESSION)
- Refactor into separate functions for each notification method
- OSC 777 remains the fallback for Ghostty, iTerm2, WezTerm, rxvt-unicode

Follow-up to #1210
BREAKING CHANGE: ToolDefinition.execute parameter order changed from
(id, params, onUpdate, ctx, signal) to (id, params, signal, onUpdate, ctx).
This aligns with AgentTool.execute so wrapping built-in tools no longer
requires parameter reordering. Update extensions by swapping signal and
onUpdate parameters.
Adds a method to access the effective system prompt (after any per-turn
extension modifications) from the extension context.
Implementation:
- Add systemPrompt getter to AgentSession reading from agent.state.systemPrompt
- Wire getSystemPrompt through ExtensionContextActions to ExtensionRunner
- Add getSystemPrompt to interactive-mode's shortcut context
- Update docs with ctx.getSystemPrompt() section
- Add system-prompt-header.ts example
- Add example to docs reference table
Closes#1098
- anthropic.ts: use model.api instead of hardcoding 'anthropic-messages'
- openai-responses.ts: use model.api instead of hardcoding 'openai-responses'
- gitlab-duo: simplify to use actual model IDs, export MODELS array
