Adds `selector`, `backendNodeId`, and `maxBytes` options to the
`markdown` tool. This allows rendering specific subtrees and capping
large outputs. Also updates the agent guidance to prefer scoped reads.
fix: address various stability and reliability issues
- Cache stderr TTY check in Config to optimize log hot path.
- Cap signal handler attempts during no-hard-exit.
- Always duplicate URL segments to prevent invalid frees.
- Write live file before backup in atomic writes.
- Settle microtasks before verifying DOM elements.
- Add diagnostics to command parsing to report invalid field values.
- Fix UTF-8 truncation in spinner to avoid splitting codepoints.
- Fix swapped arguments in log error formatting.
- Distinguish "null" values from missing elements in verifier.
- Handle MCP tool cancellation and timeouts with specific error codes.
- Limit UTF-8 walkback in `capToolOutput` to 3 bytes to prevent
excessive scanning on malformed input.
- Track consecutive backslashes in `tokenize` to correctly handle
even-count backslashes before a closing quote.
Explicitly reject backslash-escaped quotes with a clear error
message, suggesting alternative quote styles or triple quotes.
Bare backslashes (e.g. in Windows paths) remain supported.
Detects multi-line block openers (e.g., `/eval '''`) and indexes the
entire block up to its closing fence as a single span. This prevents
body lines from being indexed individually and orphaned during splicing.
Falls back to single-line indexing if the block is unterminated.
Strip carriage returns from CRLF line endings before indexing so that
LLM-supplied keys (using plain LF) match files saved with Windows
line endings. The span still covers the full CRLF sequence.
Introduces `Input.getRedactedValue` to mask password values in
LLM-facing dumps (semantic tree, forms, AXNode) instead of
exposing raw values or using ad-hoc checks.
Strips control characters from tool arguments to avoid breaking the
carriage-return redraw. Queries the terminal width and truncates
arguments to fit on a single row, appending an ellipsis if needed.
Mirrors user-typed slash commands into the message history as synthetic
tool calls. This ensures the LLM conversation remains in sync and the
next prompt can see the action's result.
Rename the system prompt constant to reflect its broader usage.
Also add instructions to guide the agent on handling follow-up
questions after navigation.
- Map common key shorthand aliases to canonical KeyboardEvent keys.
- Trigger implicit form submission when pressing Enter on inputs.
- Add CSS selector support to the press tool.
Unifies printInfo/printInfoFmt and printError/printErrorFmt into
single functions accepting format arguments. Adds printDimmed for
dimmed output and supports highlighting quoted slash arguments.
- Group `/help` output into Browser, LLM, and Meta commands.
- Only show LLM commands in help if an LLM client is configured.
- Centralize the check for commands requiring an LLM in the REPL loop.
- Add descriptions to meta and LLM commands.
