Streaming API responses (marquee). Replaced the one-shot curl/jq pipeline
with an SSE-aware path that emits text deltas as they arrive. Server-sent
events are parsed line-by-line; content_block_delta with text_delta is
flushed to stderr immediately, while tool_use blocks accumulate
input_json_delta partials until content_block_stop, validate the assembled
JSON, then execute the tool exactly as before. A synthetic response is
rebuilt from streamed blocks to keep add_assistant_blocks + cost tracking
identical to the non-streaming path. Falls back to non-streaming on parse
failure or via LARRY_NO_STREAM=1. Cite: platform.claude.com/docs/en/api/
messages-streaming for SSE event types and tool-use streaming semantics.
Fuzzy slash completion polish + descriptions. Multi-match TAB now renders
each candidate on its own line with a one-line description, cyan command +
dim description. Backed by a new _LARRY_SLASH_CMDS_DESC associative array
that mirrors print_help's wording so the two stay in sync.
Persistent command history. HISTFILE=$LARRY_HOME/.history with
HISTSIZE=1000 and HISTCONTROL=ignoredups. history -r at REPL start;
history -a after each accepted input. Skips appending /login, /ssh-pass,
and /ssh-add lines so credentials never hit the history file.
/clear slash command. Clears the terminal via the ANSI 2J/H sequence
(works without external `clear`). Distinct from /reset (which clears the
conversation, not the screen). Listed in print_help and the canonical
_LARRY_SLASH_CMDS array.
Multi-line paste auto-detection. read_user_input now reads the first line
then non-blockingly polls stdin for buffered bytes within 50ms; if more
is present, it's slurped as continuation. Also: a trailing backslash on
the first line enters a multi-line mode that ends at a blank line. The
explicit '<<' / 'EOF' heredoc still works for users who prefer it.
/copy — copy last assistant response to clipboard. Tool detection cascade:
pbcopy (macOS), wl-copy (Wayland), xclip, xsel, /dev/clipboard (Cygwin),
clip.exe (WSL/Cygwin fallback). Falls back to printing the text to stdout
with a warning when no clipboard tool is found.
/cost — running token + dollar cost. Tracks input/output/cache-read/
cache-write tokens across both streaming and non-streaming responses.
Pricing constants inline as of 2026-05 (Sonnet $3/$15, Opus $15/$75,
Haiku $1/$5, cache writes 1.25x input, cache reads 0.1x input). The /cost
report shows per-stream subtotals and a session total. Refresh constants
periodically from platform.claude.com/docs/en/about-claude/pricing.
Model name in the prompt. The prompt now reads `you[sonnet-4.6]>` (or
`you[opus-4.7]>`, etc.) derived from $LARRY_MODEL via model_short_name —
strips the `claude-` prefix and converts the trailing -N-M to .N.M. The
prompt updates immediately after /model. Color scheme preserved.
Tool-call display polish. Cyan + bold tool name, dim args one key:value
per line, long values (>120 chars) truncated with a `(use /show-last-tool
for full args)` hint. New /show-last-tool slash command prints the full
last tool call JSON + the full result body for debugging.
Friendlier error messages. Audit pass through the most common API
failures: empty response surfaces as "Network error: empty response from
<URL>"; authentication_error invites /login when OAuth/token wording
appears; rate_limit_error and overloaded_error read as "Rate limited by
Anthropic — wait a few seconds"; not_found_error includes the current
LARRY_MODEL since that's almost always the cause; jq parse errors during
tool results get wrapped as "Tool returned malformed JSON; raw body: ..."
@file inline-file syntax. The user types @<path> in any prompt; Larry
resolves each ref before send-time and appends the file contents as a
fenced block keyed by extension. Grammar supports @bare-token and
@{bracketed path with spaces}; emails (bryan@x.com) are skipped via a
look-behind on the preceding character. Validation: missing → leave
literal with warning; directory → skip; binary (null-byte scan of first
8 KB) → skip; >250 KB → truncate with a footer note. Multiple refs are
deduped. Runs BEFORE PHI tokenization so PHI markers inside attached
files still get caught. TAB after @ completes against files (find -depth
4, fzf picker when on PATH). A one-time per-session tip prints the first
time the user types @.
