feat(rust): implement missing tools, sync with JavaScript, and extract tests by konard · Pull Request #246 · link-assistant/agent

konard · 2026-04-10T21:32:01Z

Summary

Fixes #245 - Rust implementation was missing many tools compared to JavaScript codebase.

Test Extraction (New in this iteration)

Extracted ALL inline #[cfg(test)] tests from 21 source files into 22 separate test files in rust/tests/
Created lib.rs to expose modules for integration testing
Added new test cases to match JavaScript integration test coverage
Total: 236 tests pass (up from 165), clippy clean, fmt clean

New Test Files in `rust/tests/`

Test File	Tests	Coverage
`tool_bash.rs`	12	bash tool + JS compat
`tool_edit.rs`	17	edit tool + all 9 strategies
`tool_read.rs`	9	read tool + JS compat
`tool_write.rs`	7	write tool + JS compat
`tool_glob.rs`	6	glob tool + JS compat
`tool_grep.rs`	9	grep tool + JS compat
`tool_list.rs`	8	list tool + ignore patterns
`tool_batch.rs`	8	batch tool + JS compat
`tool_multiedit.rs`	4	multiedit tool
`tool_todo.rs`	7	todo read/write + JS compat
`tool_webfetch.rs`	10	HTML parsing + JS compat
`tool_websearch.rs`	3	websearch schema
`tool_codesearch.rs`	3	codesearch schema
`tool_invalid.rs`	3	invalid tool
`tool_context.rs`	3	ToolContext
`tool_registry.rs`	4	registry JS parity
`cli.rs`	43	CLI args + JS defaults
`cli_options.rs`	46	CLI binary options
`id.rs`	8	ID generation
`error.rs`	5	error types
`util_binary.rs`	6	binary detection
`util_filesystem.rs`	4	filesystem utils
`temperature_option.rs`	8	temperature option

New Rust Tool Implementations (8 tools added)

invalid.rs - Invalid tool call error handler (mirrors JS tool/invalid.ts)
todo.rs - TodoWrite and TodoRead tools with in-memory session storage (mirrors JS tool/todo.ts)
multiedit.rs - Multiple sequential edits on a single file (mirrors JS tool/multiedit.ts)
batch.rs - Parallel execution of up to 10 tools (mirrors JS tool/batch.ts)
webfetch.rs - HTTP fetch with HTML-to-text/markdown conversion (mirrors JS tool/webfetch.ts)
websearch.rs - Web search via Exa MCP API (mirrors JS tool/websearch.ts)
codesearch.rs - Code context search via Exa MCP API (mirrors JS tool/codesearch.ts)

Synced Existing Tools with JS Behavior

edit.rs - Added 5 missing replacement strategies: IndentationFlexible, EscapeNormalized, TrimmedBoundary, ContextAware, MultiOccurrence — now has all 9 strategies matching JS
list.rs - Added ignore patterns (node_modules, .git, dist, etc.) and hierarchical tree structure output matching JS ls tool
mod.rs - Registered all 15 tools to match JS ToolRegistry (was 7 tools)
bash.rs - Synced metadata format with JS (added output and exit fields)
id.rs - Added Prefix::Call variant for JS compatibility

Code Quality

All clippy warnings fixed (idiomatic patterns, unused imports)
All source formatting clean (cargo fmt)
Private helper functions made pub for external test access

Case Study Analysis

Added docs/case-studies/issue-245/README.md with:

Full JS vs Rust codebase comparison (115 JS files vs 16 Rust files)
Root cause analysis (5 identified root causes)
Impact assessment
Phased implementation plan

Tool Count: Before vs After

	Before	After
Rust tools	7	15
JS tools in registry	15	15
Edit strategies	4	9
Rust tests	165	236

Test Results

All 236 tests pass:

22 test files in rust/tests/
CLI binary integration tests
Tool unit + integration tests
Utility function tests

The loop in replace_tag_with_prefix always returned or broke on the first iteration, which clippy correctly identified as never_loop. Refactored to use an if-let chain with recursion for multiple occurrences. Also removed unused variables (open_re, offset, lower_new, search_start).

Please split all tests from src folder into tests folder for rust. Double check all tests cases are the same as in JavaScript, sync them so both implementations have maximum of the same tests coverage. And double check that all logic of JavaScript and Rust implementations are fully in sync.
