- 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.
Rename the system prompt constant to reflect its broader usage.
Also add instructions to guide the agent on handling follow-up
questions after navigation.
Replaces `printActionResult` and `printToolResult` with a single
`printToolOutcome` function. This unifies the output path and adds
red/green color coding for tool failures and successes.
- Add `/.lp-history` to `.gitignore`.
- Make `SlashCommand.MetaCommand.Tag` private.
- Simplify loop in `tools.zig` using `while ... else`.
- Use `trimStart` instead of `trim` in `Schema.splitNameRest`.
- Merge `formatHealReplacement` and `formatHealReplacementLines` using
a new `HealBody` union.
- Move `interactiveTty` and `promptNumberedChoice` to `Terminal.zig`.
- Relocate and consolidate tests for `canHeal` and `isRecorded`.
- Make internal `Schema` functions private.
- Replace `Action` enum with `Tool` enum using exhaustive switches
- Extract `ScriptIterator` to `Iterator.zig`
- Refactor `schema.zig` into `Schema.zig`
- Move string substitution logic into `tools.zig`
- Clean up `SlashCommand.zig` to only handle REPL meta-commands
Calculate the exact size needed for hint slots in schema.zig to avoid
overallocating. Also inline the single-use helper isDefaultTrueBool in
command.zig.
- Allow recording commands with backendNodeId if they also have a
selector, stripping backendNodeId during formatting.
- Point UnterminatedQuote errors to the opening line instead of EOF.
- Fix buildHints allocation when fields is empty but required is not.
- Update docs to clarify positional argument rules.
Tool calls with null arguments are now only considered recorded if the
tool schema has no required fields. This prevents generating invalid,
unreplayable commands for tools like `goto` or `fill`.
- Initialize tools once globally instead of allocating per-agent.
- Refactor meta commands to use an enum for cleaner dispatch.
- Remove unused `findSchemaCanonical` and simplify command parsing.
- Update `buildToolCall` to use `browser_tools.Action` enum.
- Trim whitespace from REPL input in `Agent.zig`.
- Replace `expectEqualStrings` with `expectString` in tests.
Replaces the string `name` in `ToolCall` with `action: browser_tools.Action`.
This avoids repeated string-to-enum parsing and simplifies schema lookups.
Also updates `zenai` dependency to use its JSON duplication helper.
- Remove `input_schema_raw` from `SchemaInfo` and use `parameters` directly
- Simplify JSON field extraction in `Verifier` to avoid `parseArgs`
- Refactor REPL command splitting and environment substitution
- Clean up and condense comments across the codebase
Remove `tool_schema_arena` from `Agent` and allocate the tools slice
directly using the general allocator.
Remove the pre-calculated `is_multiline_capable` field from
`SchemaInfo` and compute it dynamically in `isMultiLineCapable()`.
- Use global schemas built once at startup instead of parsing on init.
- Simplify argument verification using `browser_tools.parseArgs`.
- Optimize `parseValue` with `std.ArrayList`.
- Panic on global schema parse failure since schemas are static.
Inlines the browser, session, and node registry management directly
into Agent. Updates CommandRunner to use Session and Registry directly,
and calls browser_tools.call without the ToolExecutor wrapper.
- Remove unused `callEval` and `extract` from `ToolExecutor`.
- Optimize `parseValue` in `schema.zig` to allocate directly instead of
using `std.ArrayList` when filling missing defaults.
- Simplify redundant checks and clean up comments.
- Add support for triple-quoted strings (''' and """) in the tokenizer
and quote stripper.
- Avoid allocations in `stripQuotes` by returning slices.
- Optimize schema lookups using O(1) enum-based canonical resolution.
- Skip env var substitution if "$LP_" is not present in the string.
- Use `SlashCommand.globalSchemas()` instead of passing schemas around.
- Use `browser_tools.Action` enums for tool matching in Agent and Verifier.
- Optimize string substitution and quote stripping with early exits.
Unifies PandaScript syntax by replacing uppercase keywords with slash
commands (e.g., `/goto`, `/click`, `/fill`). Refactors the `Command`
representation to use a generic tool call structure backed by schemas.
BREAKING CHANGE: Uppercase PandaScript keywords (GOTO, CLICK, TYPE, etc.)
are no longer supported. All scripts must use slash commands.
Update `Recorder.init` to accept a `std.fs.Dir` and relative path,
decoupling it from the current working directory.
Also add a persistent arena allocator to `Recorder` to reuse
allocations when scrubbing environment variables on each write.
Renames `Command.zig` to `command.zig` and moves associated functions
like `parse`, `toToolCall`, and `canHeal` directly into the `Command`
union. This simplifies usage from `Command.Command` to just `Command`.
- Replace `Self` with `Recorder` and `Verifier` for improved clarity.
- Add `Spinner.isEnabled()` to encapsulate atomic state access.
- Shorten and refine various comments across the codebase.
- Make `VerifyResult.failed` reason non-optional with an OOM fallback.
- Use `ElementProperty` enum for safer JS property injection.
- Ensure `Recorder` disables on all errors to prevent silent data loss.
- Add `CHECK` command round-trip test.
- Prevent UB in `applyReplacements` with pointer assertions.
- Reorder `writeAtomic` to build content before writing backup.
- Strip trailing `\r` in `ScriptIterator` for CRLF compatibility.
- Use shorter representation for `SCROLL` commands.
- Filter redundant `extract` calls in recordings to reduce noise.
- Scrub literal `LP_*` secrets from recorded commands for portability.
- Throw a descriptive error in `extract` when no selectors match.
- Update tool descriptions and guidance to favor a `tree` ->
`nodeDetails` -> `extract` workflow for more robust selectors.
Adds the `extract` tool for lifting structured data via JSON schemas.
Updates the command system to support recording and replaying
extraction steps in PandaScript.
Replaces the struct-based result with a tagged union to represent
verification outcomes more idiomatically. Updates callers in Agent
and MCP tools to handle the new union type.
Changes `EvalResult` to a union and uses Zig errors for operational
failures, distinguishing them from JavaScript execution errors.
Also removes redundant `stringifyJson` in favor of standard library.
- Derives the `Action` enum in `src/browser/tools.zig` from `tool_defs` to prevent manual maintenance and potential drift.
- Refactors `verifyElementValue` in `src/script/Verifier.zig` to use a `Check` struct for its parameters.
- Reorganizes and cleans up imports in `src/agent/Agent.zig`.
