Engine retries transient errors (429, 5xx) up to 4 times with
1s/2s/4s/8s backoff. Respects Retry-After header from provider.
Batch tool staggers elf spawns by 300ms to avoid rate limit bursts
when all elfs hit the API simultaneously (Mistral's 1 req/s limit).
- Elf tool calls show as 🦉 [elf] <prompt> (not ⚙ [agent])
- Live 2-line progress beneath the elf label showing what the
elf is currently outputting (grey, auto-updated)
- Agent tool forwards elf streaming events via progress channel
- Progress cleared on turn completion
- elfProgressCh wired from agent tool → TUI
internal/elf/:
- BackgroundElf: runs on own goroutine with independent engine,
history, and provider. No shared mutable state.
- Manager: spawns elfs via router.Select() (picks best arm per
task type), tracks lifecycle, WaitAll(), CancelAll(), Cleanup().
internal/tool/agent/:
- Agent tool: LLM can call 'agent' to spawn sub-agents.
Supports task_type hint for routing, wait/background mode.
5-minute timeout, context cancellation propagated.
Concurrent tool execution:
- Read-only tools (fs.read, fs.grep, fs.glob, etc.) execute in
parallel via goroutines.
- Write tools (bash, fs.write, fs.edit) execute sequentially.
- Partition by tool.IsReadOnly().
TUI: /elf command explains how to use sub-agents.
5 elf tests. Exit criteria: parent spawns 3 background elfs on
different providers, collects and synthesizes results.
System prompt gets a one-line summary (~200 chars): OS, CPU, RAM,
GPU, top runtimes, package count, PATH command count.
Full details available on demand via system_info tool with sections:
runtimes, packages, tools, hardware, all. LLM calls the tool when
it needs specifics — saves thousands of tokens per request.
Hardware detection: CPU model, core count, total RAM, GPU via lspci.
Package manager: pacman/apt/dnf/brew with dev package filtering.
PATH scan: 5541 executables. Runtime probing: 22 detected.
No hardcoded tool lists. Scans all $PATH directories for executables
(5541 on this system), then probes known runtime patterns for version
info (23 detected: Go, Python, Node, Rust, Ruby, Perl, Java, Dart,
Deno, Bun, Lua, LuaJIT, Guile, GCC, Clang, NASM + package managers).
System prompt includes: OS, shell, runtime versions, and notable
tools (git, docker, kubectl, fzf, rg, etc.) from the full PATH scan.
Total executable count reported so the LLM knows the full scope.
Milestones updated: M6 fixed context prefix, M12 multimodality.
