Replaces the fragile `firstSentence` parser with an explicit `summary`
field on tool definitions. Also standardizes user-facing REPL
terminology to "command" instead of "slash command" or "tool".
* agent: add a /model command to chnage current model
And remove the pick-model CLI option
* agent: add /provider to change the current provider
* agent: extract requireLlmNoArg helper
* agent: simplify provider detection
* repl: add tab completion for /model and /provider
Changes `/model` and `/provider` to accept an optional name argument
instead of prompting with a numbered list. Bare commands now print the
current selection, while Tab dynamically completes candidates. Model
lists are fetched and cached to prevent redundant network requests.
* agent: remember last selected provider and model
Persists the last selected AI provider and model in a local
`.lp-agent` file and resumes it on startup. Removes the
interactive provider picker in favor of deterministic auto-detection.
* agent: simplify requireLlm and model resolution
Changes `requireLlm` to return a boolean instead of credentials, and
cleans up the model initialization logic to use `resolved` directly.
Also removes unused user errors.

- Remove unused parameters from save helper functions.
- Inline and simplify save path duplication and file writing.
- Clean up optional unwrapping for the recorder.
Add a REPL-only `/save [filename.lp]` command that persists the current
interactive session as PandaScript without requiring the user to start the
agent with `-i <script>`. The command records the same replayable actions as
the existing script recorder, but keeps them in memory until the user chooses
to save.
Functional behavior:
- During a REPL session, record replayable browser actions into an in-memory
script buffer.
- Manual slash commands are recorded through the same PandaScript formatting
and filtering rules used by file recording.
- Natural-language turns record their prompt as a `# ...` comment only when
the LLM turn produces at least one successful replayable tool call.
- Failed LLM tool calls are skipped, and repeated successful `/extract` calls
keep only the last successful extract, matching the existing recorder logic.
- `/save filename.lp` writes the current in-memory recording to that file.
- Bare `/save` creates a random `session-<hex>.lp` file on first save.
- If the first save targets an existing file, prompt with the existing numbered
TTY picker and ask whether to replace or append.
- After the first successful save, the REPL session is locked to that filename:
later `/save` or `/save same-file.lp` appends to the same file without
prompting, while `/save other-file.lp` is rejected.
- After each successful save, reset the in-memory recorder so future saves only
append actions entered since the previous save.
- On any `/save` error or cancellation, keep the in-memory recorder intact so
the user can retry without losing captured actions.
- Restrict `/save` filenames to local file names, not paths, to keep behavior
scoped to the current directory.
Code changes:
- Add `Recorder.Memory`, an in-memory recorder that shares the existing
`Command.isRecorded`, `Command.format`, comment formatting, and `LP_*`
reverse-substitution behavior with file recording.
- Add `Recorder.Memory.reset()` so `/save` can clear only successfully saved
deltas.
- Add `/save` to the REPL meta command table and help/completion surface.
- Add `save_buffer` and `save_path` state to `Agent`.
- Feed manual REPL tool calls into `save_buffer` alongside the existing optional
file recorder.
- Extend LLM turn recording with a `capture_for_save` flag so natural-language
REPL turns can be captured without affecting non-REPL script/self-heal paths.
- Implement `/save` handling in `Agent`:
- parse and validate the optional filename,
- choose replace/append for existing first-save targets,
- remember the first successful save path,
- enforce the single-destination rule for the rest of the session,
- append later deltas by default,
- commit remembered path state only after a successful file write.
- Add focused coverage for the memory recorder’s filtering and reset behavior.
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.
- 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.
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.
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.
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.
- 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
- 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.
