docker-agent

This release adds several new built-in toolsets (git, webhook), budget limits, .agentsignore support, expanded Mermaid rendering, image rendering in the TUI, and numerous TUI improvements including per-agent usage details, session browser enhancements, and argument auto-completion for slash commands.

What's New

• Adds a read-only git toolset (git_status, git_log, git_branches, git_show, git_blame) giving agents structured access to the working repository without requiring a git binary
• Adds a webhook toolset with a send_webhook tool that lets agents send outbound notifications to a configured chat service without exposing the URL or secret to the model
• Adds budget configuration (budget / budgets) to cap what an agent may spend in cost, tokens, or working time, with live tracking in the TUI sidebar
• Adds .agentsignore support — a .gitignore-syntax file that prevents the agent from listing, reading, or writing matched files
• Adds image rendering in the TUI for tool result images and markdown images in agent responses (using the Kitty graphics protocol, with a setting to disable)
• Adds an image rendering preference to settings
• Adds Mermaid flowchart direction support and subgraph rendering
• Adds argument auto-completion for /toolset-restart, /drop, and /effort slash commands
• Adds per-agent usage details to the TUI sidebar, with a new sidebar info mode selector in /settings
• Adds fuzzy search matching for tool discovery via search_tool in the deferred toolset
• Adds Claude Code harness setup and diagnostics as a new docker agent setup path
• Adds explicit prompt cache breakpoint support for OpenAI (GPT-5.6+)
• Extends session browser search to match session IDs in addition to titles
• Groups the session browser by git repository root (worktree-aware)
• Allows configuring compaction_model directly on an agent as a sibling to compaction_threshold
• Opens the /cost dialog when clicking the sidebar cost/token usage reading
• Adds a self-maintaining llms.txt generated from nav.yml at Hugo build time

Improvements

• Fixes severe scrolling performance on very large sessions by caching rendered lines in the cost dialog and stopping message-list render cache thrashing
• Keeps the /cost dialog cache fresh on live updates and theme changes
• Shows usage and team roster in the collapsed sidebar band from startup
• Adds sidebar agent info modes

Bug Fixes

• Fixes RAG query embedding usage tracking so tokens are correctly attributed and emitted to the active session
• Fixes telemetry model dimension pollution and captures partial usage in RAG
• Fixes Anthropic system cache breakpoints being exceeded by capping them so requests never exceed the limit
• Fixes transcripts carrying cache checkpoint marks after compaction
• Fixes slash command inline completion to match on command value, not just label (e.g. typing /settings now surfaces the Settings command)
• Fixes TUI panic when the terminal reports a degenerate (0×0 or 1×1) size
• Fixes the /cost dialog cache not refreshing on live updates and theme changes
• Fixes the sidebar scrollbar clicks registering in content click zones
• Fixes the settings command label to display consistently as Settings
• Fixes right-to-left Mermaid connector rendering
• Fixes HTTP error statuses (4xx/5xx) being swallowed and treated as success in the API tool
• Fixes webhook tool to sanitize *url.Error to prevent secret URL leakage
• Fixes MCP OAuth clients with allow-private-ips to use a private connection pool instead of sharing http.DefaultTransport
• Fixes flaky OAuth tests by not sharing http.DefaultTransport across parallel tests
• Fixes the template Docker build stage to use COPY --from instead of an unauthenticated GitHub API call that hit rate limits
• Removes macOS Keychain and pass secret providers from DefaultSources

Technical Changes

• Freezes config schema v12 and opens v13 as the new latest
• Refactors Anthropic prompt-cache checkpoint handling into consolidated owners, making known failure modes structurally impossible
• Refreshes the embedded models.dev snapshot
• Drops the unused benchmarks/ folder
• Exposes the current agent's supported thinking levels from the runtime
