- `available_providers` holds the static enum tag names; drop the dupe
loop, its errdefer and the per-string frees.
- `reconcileModel` returns `error.ModelNotAvailable` directly instead of
a `use`/`abort` union the caller only mapped to that same error.
- `runCommand`/`printCommandResult` take `Command.ToolCall`; the caller
already has it, so the unreachable "no tool mapping" branches go.
- `handleSave` reuses `rememberSavePath`, which now propagates its
allocation failure so a first save under OOM warns instead of
unwrapping a null `save_path`.
- `SlashCommand.all_names` is a comptime `++` of the three name lists.
- `buildUserMessageParts` reads the attachment once for both text and
image, and prepends the text part instead of copying the list.
- `printSeverity`/`formatBulletLine` use `allocPrint` and the shared
`emitStderr`; drop an unreachable `ends_ws` check in `renderMetaHint`.
An unknown --flag now logs the nearest accepted spelling within two
edits as did_you_mean, painted green next to the red typo in the pretty
log format; logfmt stays plain. A bare first argument within two edits
of a command name is rejected with the same hint instead of being
fetched as a url.
The Levenshtein helper moves from SlashCommand into string.zig so the
agent REPL and the CLI share it, with the table widened to fit the
longest flag name.
Add Brave as a second API-backed web search engine: the search tool's
auto mode tries Brave then Tavily (keyed on BRAVE_API_KEY/TAVILY_API_KEY)
before the DuckDuckGo scrape. A new /searchEngine REPL metacommand pins
the engine explicitly (auto|tavily|brave|duckduckgo) — an explicit
engine surfaces its failures instead of silently degrading — and is
persisted to .lp-agent.zon like the other REPL settings.
Bumps zenai to pick up the zenai.search.brave client.
- attachCompleter now takes the CompletionSource: Agent no longer
reaches through terminal.assist to configure what it just attached,
and attach/configure can't be sequenced wrong.
- history_paths flows through one channel: attach() loads the initial
history from the same State field modeCallback swaps from, instead of
setupRepl receiving a second copy that had to agree.
- all_names + closestCommand move to SlashCommand.zig, the command
registry - prompt_assist consumes it like everyone else and
Terminal's closestCommand re-export disappears.
- picker treats a tty that refuses raw mode as NotInteractive and
degrades to the line prompt instead of leaking termios errnos to
callers that can only blanket-catch.
- kitty keyboard flags become named ansi.zig constants shared by
Terminal.readLine and picker's RawTerminal.
- skipWhitespace was std.mem.indexOfNonePos; single-use style consts
inline into the style table; drop the dead CompletionSource default
and doc-comment splice in Spinner.
Moves `tagNames` and `tagHint` from `SlashCommand` to `Config` for reuse.
Adds `tagJsonArray` to dynamically generate JSON enum schemas, and
uses it in `tools.zig` for the `WaitUntil` enum.
Adds support for `/provider null` to disable the LLM and persist this
preference in `.lp-agent.zon`. Subsequent REPL launches will start
in basic mode without prompting for API keys. Transient `--no-llm`
runs do not clobber the saved provider.
- `/clear` forgets conversation history, usage, and node IDs while
keeping the loaded page and cookies.
- `/reset` does a full reset, starting a fresh browser session.
Removes the `-i`/`--interactive` CLI flag and live file-based
recording. Instead, the REPL now supports a `/load <path>` command
to run scripts from disk, and `/save` to export the in-memory
session recording.
The `Recorder` is simplified to be purely in-memory, and the script
runtime is moved to `src/script/Runtime.zig`.
BREAKING CHANGE: The `-i`/`--interactive` flag has been removed. Use
the `/save` and `/load` commands within the REPL instead.
Removes the `--self-heal` CLI option, the `scriptStep` and `scriptHeal`
MCP tools, and associated verification/iterator machinery. Replaces
"PandaScript" terminology with "slash commands" and moves shared
helpers to `tools.zig`.
BREAKING CHANGE: The `--self-heal` CLI flag and the `scriptStep` and
`scriptHeal` MCP tools have been removed.
Replace recorded agent replay with a standalone JavaScript script runtime.
Install synchronous agent primitives in an isolated V8 context, add console
output, return structured extract values as JS objects/arrays, and route script
execution through the new runtime.
Update recording to emit .js function calls, default /save filenames to .js,
drop script-level extract save support, and refresh agent docs/tutorials for
the new format.
Self-healing is disabled for now.
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.

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.
- 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.
- 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`.
- 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.
- 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
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.
- 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.
- Replace `unreachable` with explicit error returns in Agent and Executor.
- Add `EvalResult.err` helper in `tools.zig` to simplify error paths.
- Improve error propagation in `SlashCommand` and `Recorder`.
- Rename `Self` to `Agent` for better clarity in function signatures.
- Use `SlashCommand.splitNameRest` for cleaner command handling.
- Centralize `max_hint_slots` constant and add assertions.
- Refactor `Spinner` thread management and rendering code.
- Cache environment variable names to improve completion performance.
- Refactor terminal styles into constants.
- Move `isAllUpper` to `string.zig` and `meta_names` to `SlashCommand.zig`.
- Align quoted string scanning logic with the slash command parser.
