The existing gmail.list and gmail.search tools only return snippets.
gmail.read fetches the full message by ID using format: 'full', decodes
base64url body parts (preferring text/plain, falling back to stripped
HTML), and returns headers + body text. This enables workflows like
searching for invoices and extracting amounts from the full content.

Add calendar.today, calendar.list, calendar.search tools mirroring the
Gmail tool pattern. Includes gcal-auth CLI command, config schema, tool
policy entries (messaging/coding profiles + group:gcal), and 17 tests.
Also wires up gmail and gcal tool registration in the daemon and TUI.

- assembleSystemPrompt() now injects '# Runtime Context' with current date/time
- New system.info tool: date, time, hostname, platform, arch, uptime, memory, Node.js version
- Tool available in all profiles (minimal/messaging/coding/full)
- 983 tests passing (+7 new)
Implements apply_patch equivalent: a single tool call can make multiple
line-based edits (replacements, insertions, deletions) across one or more
files. Hunks are applied bottom-up to preserve line numbers.
Includes 10 tests covering replacement, multi-hunk, insertion, deletion,
multi-file, overlapping hunks error, OOB error, and edge cases.
Five additive features with no breaking changes:
- Tool groups: group:fs, group:runtime, group:web, group:memory syntactic
sugar for allow/deny lists in tool policy config
- Typing indicators: Discord sendTyping() and WhatsApp sendStateTyping()
on message receipt for better UX feedback
- Session pruning: TTL-based auto-cleanup via sessions.ttl config with
hourly daemon timer and SQLite GROUP BY pruning
- /verbose command: TUI command parser toggle for raw streaming display
- !!think prefix: per-message extended thinking mode wired through
Anthropic (budget_tokens), OpenAI/GitHub (reasoning_effort), and
Gemini (thinkingConfig) providers

Add 8 new agent-callable tools (sessions.list/history/create/delete,
agents.list, message.send, cron.list/trigger) and sanitize tool names
at the API boundary (dots → underscores) to comply with Anthropic's
`^[a-zA-Z0-9_-]{1,128}` requirement. Reverse-maps sanitized names
back to internal names for hook callbacks and tool execution.

Introduces OutboundAttachment type on OutboundMessage, an
OutboundAttachmentCollector (push/drain pattern), and a media.send
tool that queues files for outbound delivery. Each channel adapter
(Telegram, Discord, Slack, WhatsApp) sends attachments after the
text reply. Includes 15 tests for collector and tool.
Provides a factory createImageAnalyzeTool(modelClient) that sends images
to a vision-capable model and returns a textual analysis. Includes 15
tests covering base64, URL, multi-image, error, and edge cases.
Add BrowserManager (puppeteer-core) with page pool and auto-detection of
Chrome/Chromium. Six tools: browser.navigate, browser.screenshot,
browser.click, browser.type, browser.content, browser.eval. Feature is
opt-in (browser.enabled defaults to false). Add to coding tool profile.
Includes 22 unit tests for manager and all tools.
Implement Model Context Protocol (MCP) support so Flynn can spawn MCP
server processes, discover their tools, and make them available to the
agent alongside builtin tools.
- McpClient: wraps @modelcontextprotocol/sdk with StdioClientTransport
for process lifecycle, tool discovery (listTools), and invocation (callTool)
- McpManager: lifecycle management for multiple MCP servers with
startAll/stopAll/restart, tool bridging into ToolRegistry
- Bridge: converts MCP tools to Flynn Tool interface with mcp:<server>:<tool>
namespacing to avoid collisions with builtin tools
- Config: add env and cwd fields to mcp server schema
- ToolRegistry: add unregister() method for MCP server cleanup
- Daemon: wire McpManager into startup and shutdown lifecycle
- Tests: 28 new tests (bridge, manager, registry unregister)
Tests the full agent -> tool execution -> model feedback loop:
- Shell tool execution with mock model
- Multi-tool chaining (file.write -> file.read) across iterations
- Verification that tool results are correctly passed back to model
