Patchloom for VS Code

This release aligns the extension with Patchloom CLI v0.6.0, the biggest CLI release to date: 41 PRs, 112 files changed, and 1,816 tests.

What's new in the CLI

11 AST tools for code-aware agents

The CLI's MCP server now exposes 43 tools (up from 32), with 11 new AST tools powered by tree-sitter:

Tool What it does
ast_list List symbol definitions (functions, classes, structs) across 20 languages
ast_read Read a specific symbol's source code by name
ast_rename Rename identifiers across files (skips strings and comments)
ast_validate Check syntax and report parse errors with line numbers
ast_search Structural search using tree-sitter queries and code patterns
ast_refs Find all references to a symbol, distinguishing definitions from uses
ast_deps Extract import/dependency statements from source files
ast_map Generate a ranked repository map using PageRank over the symbol graph
ast_diff Structural diff showing added, removed, and modified symbols
ast_impact Transitive impact analysis: trace dependents through the reference graph
ast_replace Replace text only within a specific symbol's body

Declarative MCP tool registry

The MCP server architecture was rebuilt around a declarative registry. Tool schemas are derived directly from Rust types via schemars, eliminating schema drift between CLI operations and MCP tools.

Performance improvements

  • spawn_blocking for all sync I/O on Tokio's blocking thread pool, critical for HTTP/HTTPS transport under concurrent requests
  • Tree-sitter parse tree caching for repeated AST queries against the same file
  • PageRank convergence using L1-norm (threshold 1e-6) instead of fixed iterations

Bug fixes

  • doc flatten now includes empty arrays and empty objects instead of silently dropping them
  • Transaction engine preserves idempotent delete semantics within a plan
  • search --jsonl with zero matches returns exit code 3 consistently
  • ast_rename with a no-op rename returns early instead of rewriting files identically
  • Git argument injection blocked across all commands that accept paths
  • Concurrent-write warnings added to all MCP tool descriptions

Install or update the CLI

brew upgrade patchloom           # Homebrew
cargo install patchloom          # crates.io

Or run Patchloom: Update Patchloom from the VS Code command palette if using the managed installer.
