New tools:
- get_architecture: codebase architecture overview with 12 selectable aspects
(languages, packages, entry_points, routes, hotspots, boundaries, services,
layers, clusters, file_tree, adr)
- manage_adr: CRUD for Architecture Decision Records with 6 fixed sections,
section filtering, validation, and discovery of existing architecture docs
Architecture analysis fixes:
- Fix qnToPackage extracting segment[2] for meaningful sub-packages instead
of segment[1] which collapsed everything to top-level dirs
- Filter test functions from entry_points, hotspots, and routes using both
is_test property (Module/File nodes) and file_path pattern matching
- Filter boundaries to Function/Method/Class nodes only
- Add FindArchitectureDocs for discovering existing architecture documentation
Naming corrections:
- Rename Leiden to Louvain throughout (algorithm is simplified Louvain,
not actual Leiden which requires CPM-based refinement)
- leiden.go -> louvain.go with all symbols renamed
- Remove unused ClusterInfo.Modularity field (always zero)
Other changes:
- Case-insensitive search by default for search_graph and search_code
- Remove read_file and list_directory tools (handled by coding agents natively)
- Update tool descriptions and README for 8000 char ADR limit
- Release workflow: build binary as `codebase-memory-mcp` (not
`codebase-memory-mcp-<os>-<arch>`) inside tarballs. Users extract
and get the correct name without renaming.
- Codex CLI: replace broken `codex mcp add/remove` calls with direct
config.toml manipulation. Codex uses [mcp_servers.<name>] sections,
not CLI subcommands.
- README: add explicit extract-and-move step to Quick Start.
claude mcp remove without -s user prompts interactively for scope,
which hangs when run from install/uninstall commands. Both
registerClaudeCodeMCP (pre-cleanup remove) and deregisterMCP
(uninstall) now pass -s user explicitly.
- TestMain: append .exe to binary name on Windows
- Add testEnvWithHome/setTestHome helpers for cross-platform HOME override
(Windows uses USERPROFILE, not HOME)
- Add exeSuffix() helper for fake binary creation
- Skip Unix-specific tests on Windows: shell RC detection, PATH append,
fallback path lookup
- Normalize CRLF in skill frontmatter check (git may convert on Windows)
Skill files were only written inside installClaudeCode(), which required
finding the `claude` CLI binary. In CI (Linux) with no claude installed,
skills were never written, causing 4 test failures.
Split into installSkills() (always runs) and registerClaudeCodeMCP()
(only when claude CLI found).
- Feature line: list all 35 languages including Obj-C, Swift, Dart,
Perl, Groovy, Erlang, R, SCSS, SQL, Dockerfile
- Performance section: updated with Django (49K nodes) and Linux
kernel stress test numbers from the v0.3.0 benchmark
- Architecture section: 25 → 35 language specs
- Token efficiency: reference 35 real-world repos instead of single project
Three bugs prevented the update notice from appearing:
- checkForUpdate goroutine launched after blocking sessionOnce.Do,
so it never ran before tool calls arrived
- 4KB body limit truncated the ~15KB GitHub API response
- Notice was a JSON map key with no guaranteed ordering
Fixes:
- Move go checkForUpdate() before sessionOnce.Do in all handlers
- Increase body read limit to 64KB
- Prepend notice as separate MCP TextContent block (appears first)
- Link to GitHub releases page instead of go install command
C# was listed as a supported language but every .cs file produced
"unsupported language: c-sharp" because the tree-sitter grammar was
never wired up. The comment cited a "module path mismatch", but
github.com/tree-sitter/tree-sitter-c-sharp is a valid Go module path
(hyphens are allowed); the Go package inside simply uses underscores
(tree_sitter_c_sharp), which is standard Go convention.
Fix: add the import and map lang.CSharp to tree_sitter_c_sharp.Language()
in parser.go. Also remove the C# skip from TestAllLanguagesLoad and add
TestParseCSharp to verify class and method parsing.

Add CLI mode for direct tool invocation from the shell — every MCP tool
can now be called without an MCP client. Useful for testing, scripting,
and CI pipelines.
Query engine rewrite: SQL LIKE pre-filtering extracts literal substrings
from regex patterns before scanning, batch degree counting replaces
per-node queries, and schema queries use id→label maps instead of 3-way
JOINs. Cypher relationship queries up to 600x faster on large graphs.
Incremental reindex 4x faster via content-hash skip optimization.
Upgrade to Go 1.26 (Green Tea GC) and SQLite v1.46.1.
Auto-sync: background watcher polls indexed projects for file changes
(mtime+size) and triggers incremental re-indexing automatically. Adaptive
polling interval scales with repo size (1s-60s). Non-blocking — uses
TryLock to skip if manual index_repository is in progress.
WithTransaction: changed signature to return a transaction-scoped Store
instead of mutating the shared querier field. Eliminates a data race
where concurrent read handlers could use a committed transaction.
Infrastructure file indexing: new pipeline pass indexes Dockerfiles,
docker-compose, cloudbuild, .env, Terraform, and YAML config files as
InfraFile nodes with structured properties.
Also includes: indexMu mutex on Server for safe concurrent access,
Claude Code skill file in repo, updated README with auto-sync docs.
Clarify that search_graph relationship filter counts node degrees
(not edges), direct users to query_graph Cypher for listing
HTTP_CALLS/ASYNC_CALLS edges with properties, and recommend
direction=both in trace_call_path for full cross-service context.
- detect_platform() now checks hw.optional.arm64 sysctl on macOS to
pick the arm64 binary even when bash runs under Rosetta (uname -m
reports x86_64 in that case)
- Move tmpdir to a global CLEANUP_DIR so the EXIT trap does not hit
an unbound variable error from set -u after the function returns
Lead with pre-built binary download (no toolchain needed), then setup
scripts for automation, then build-from-source for contributors.
- Add platform table with all 5 targets including linux-arm64
- Add Windows SmartScreen guidance for unsigned binary
- Document checksums.txt for integrity verification
- Credit @Flipper1994 for WSL2 workaround (closes#1)
