pawan-core v0.5.0

Core library for the Pawan CLI coding agent. Contains the agent engine, tool system, configuration, and healing/recovery logic.

What's New in v0.5.0

Session store — SQLite in WAL mode with FTS5 and JSON migration; JSONL branching with parent_id (depth capped at 5); session labels and bookmarks
Agent pool — concurrent agents with semaphore bounding; agent definitions with YAML frontmatter; 6 agent types, 300s timeout
Parallel tool execution — bounded concurrency (max_parallel_tools); batch tool (25 concurrent calls)
Bash permission tiers — tree-sitter based, feature-gated with main/sub/lua audience bitflags
Doom-loop detection — configurable backoff multiplier; retry policy with exponential backoff + jitter
Auto-compaction — LLM summarization via /compact; strategies: default (10 msgs), aggressive (5 msgs), conservative (20 msgs)
Memory system — consolidation (Jaccard similarity), retrieval, prompt injection scanner (6 patterns), SessionScopedMemory fencing
Tool registry overhaul — Tool::execute now async; on_pre_compress hook for context pre-processing; sync_turn on return
Module splits — coordinator/types.rs extracted; tools/git.rs → tools/git/ (5 files); tools/native.rs split into native_search, mise, lsp_tool
208 tests passing (173 library + 35 CLI integration)

What's New in v0.4.8

Shell-like command history navigation — Up/down arrow keys navigate through command history, matching bash/zsh/Claude Code/OMP behavior
History persistence — Commands saved to history (excluding slash commands), accessible across sessions

What's New in v0.4.7

Redesigned keyboard shortcuts — Ctrl+C always clears input, Ctrl+Q quits for cleaner separation of concerns

What's New in v0.4.6

Redesigned Ctrl+C behavior — Clears input when non-empty, quits when empty (matching bash/zsh pattern)

What's New in v0.4.1

Session tags UI — Visual green tags in status bar, manage via /tag command
Fuzzy session search — Fuzzy matching with [FUZZY] indicator in session browser
NVIDIA NIM catalog — /models command to browse available NIM models
Enhanced /diff — --cached flag support and colorized diff output
Improved /load and /resume — Opens session browser when called without arguments
Enhanced scrolling — PageUp/PageDown/Home/End keys and mouse wheel support in all popups (command palette, slash menu, session browser)
Secure credential storage — API keys stored in OS-native credential store (Keychain/Credential Manager/libsecret)
Test stability — All 789 library tests and 59 integration tests now pass consistently

Features

Agent Engine — Multi-turn conversation with LLM backends (NVIDIA NIM, Ollama, OpenAI, MLX)
Tool System — 34 tools in 3 tiers (Core/Standard/Extended) with tiered visibility
Configuration — Pluggable config resolution via aegis or local files
Healing — Auto-recovery from tool failures, context overflow, model errors
Thinking Budget — Per-model thinking mode dispatch (Qwen, Gemma, Mistral, DeepSeek)
Session Management — Save, load, and resume conversation sessions
Model Selection — Dynamic model switching with search and filtering

Usage

use pawan::{PawanAgent, PawanConfig};
use std::path::PathBuf;

let config = PawanConfig::load(None)?;
let _agent = PawanAgent::new(config, PathBuf::from("."));

This crate is the foundation — use pawan (the CLI binary) for the full experience.
