Built-in slash commands: autocomplete and dispatch#148
Merged
Conversation
Built-in slash commands (/new, /model, /compact, /session, /name, /fork, /resume, /reload, /export, /copy, /quit) were not autocompleted or dispatched locally — they were sent verbatim as prompts, causing the LLM to respond about them instead of executing them. Dispatch table and autocomplete Data-driven table in ui.el maps command names to existing handler functions with an :args spec (nil, optional, required). Autocomplete in input.el merges builtin names with RPC-provided commands. Dispatch in render.el replaces the old /compact-only special case. Fix session state reads in menu functions Menu functions (model description, thinking description, select-model) read pi-coding-agent--state directly, but state is buffer-local in the chat buffer. When called from the input buffer, state was nil giving 'unknown'. New --menu-state accessor reads via buffer-local-value. Model selector improvements Shortened display names (Opus 4.6 not Claude Opus 4.6), matching the header-line. Case-insensitive flex completion so 'opus' matches 'Opus 4.6' and 'code' matches 'GPT-5.1 Codex Max'. Unique flex match auto-selects without opening the picker (/model op46 sets Opus 4.6 directly). No match prints a message; multiple matches open the picker pre-filled. Argument passing for /model and /export /model accepts optional search text as initial-input. /export accepts optional output path, sent as :outputPath in the RPC. Interactive C-c C-p e now prompts for export path (RET for default).

What changed
Built-in slash commands now autocomplete and work from the input buffer. Previously, typing
/newor/modelsent the text as a prompt to the LLM instead of executing the command.Fixes #143
All built-in commands work
/new,/model,/compact,/session,/name,/fork,/resume,/reload,/export,/copy,/quit— all dispatch locally. Extension and skill commands (/pisay,/skill:brave-search, etc.) still pass through to pi as before.Model selector improvements
opusmatches "Opus 4.6",codematches "GPT-5.1 Codex Max" (case-insensitive flex completion)/model sparksets the model directly without opening the picker;/model opusopens the picker pre-filled since multiple Opus models existSlash commands accept arguments
/model opus— pre-fills/auto-selects in the model picker/model zzzzz— prints "No model matching" instead of opening an empty picker/export /tmp/out.html— exports to a custom path/compact keep API details— passes custom compaction instructions/name my-session— sets name directly;/namewithout arg prompts interactivelyC-c C-p enow prompts for export path (RET for default)Fix: "current: unknown" in model selector
The model selector and transient menu showed "unknown" when invoked from the input buffer (where the cursor normally lives), because session state is buffer-local in the chat buffer. Now reads state correctly from either buffer.
