v0.7.0

0.7.0 — 2026-06-12

Close out the roadmap backlog: path tracing, a complete MCP surface, and
extractor/resolver correctness and performance work.

Added

• dekko trace FROM TO — shortest call path(s) between two symbols over
  the resolved graph (--max-paths K, --json). "No path" is a clean
  exit 1, not an error; unknown/ambiguous endpoints exit 3/4 like
  the other read commands. It auto-regenerates a stale map.
• Three new MCP tools so the server now mirrors the whole read surface
  (nine tools): trace_path, find_unused, and stats.
• dekko map --jobs N — parallel extraction across a process pool
  (0 = all cores; sequential by default). Cache hits stay in-process and
  results re-assemble in discovery order, so output is identical to a
  single-worker run.
• dekko --claude-uninstall — reverses --claude-install, removing the
  bundled plugin and its marketplace registration.
• dekko --mcp-uninstall — reverses --mcp-install, removing the
  standalone MCP server (claude mcp remove dekko).

Changed

• The .dekko extraction cache is now tagged with the dekko
  version and discarded on a version change, so an upgrade re-parses once
  and always reflects extractor changes (no manual --full).
• Resolver same-file and self-container checks use a pre-built
  (name, path) bucket instead of rescanning every repo-wide candidate,
  cutting the worst case for very common names. Resolution results are
  unchanged.
• Renamed from lidar-map / lidar to dekko / dekko before the
  first PyPI release. The PyPI package, CLI command, Python import package,
  cache directory (.dekko/), and MCP server name all changed; no published
  packages were affected.
• MAP.md and map.json are now written into the .dekko/ directory by
  default (alongside the cache) instead of the repository root; --output
  still overrides the location.

Fixed

• Relative-import sources no longer double the leading dot
  (from . import x rendered as ..x); they now read .x / ..x /
  .pkg.x correctly in context packs.
• install.sh invokes the freshly installed CLI by absolute path — a
  repo-local .venv/bin/dekko could shadow it on PATH and break
  --claude-install — and forces a rebuild with --refresh-package, so a
  re-install at the same version no longer reuses a stale cached wheel.

Documented

• A "Limitations" section in the README: calls inside Rust macro bodies
  are invisible to tree-sitter token trees, and dynamic dispatch has no
  static call site.

0.6.0 — 2026-06-12

Graph analysis: turn the map into a source of code-health insight.

Added

• dekko unused — symbols with no inbound calls, minus roots (main,
  test files, decorated/annotated symbols, the language's public surface
  — Rust pub, Go capitals, Java public, JS/TS export — Python
  dunders and __init__.py re-exports, plus --roots GLOB). A class is
  kept when any of its methods is called. --limit, --json; exits 1
  when any are found. It is call-graph based, so it reports leads, not
  verdicts.
• dekko stats — file/symbol/edge totals, language mix, top fan-in/out
  hotspots, and largest files (--top, --json).
• dekko export — render the call graph as --format mermaid|dot, at
  --scope symbol|file, with a --max-nodes guard.
• Symbol now records decorated and exported facts (Python
  decorators, Rust attributes/pub, Java annotations/public, JS/TS
  decorators/export), serialized into map.json.
• A test asserting the four declared version strings (pyproject, both
  plugin manifests, uv.lock) agree.

0.5.0 — 2026-06-12

Expose the map to agents over the Model Context Protocol.

Added

• dekko serve --mcp — a hand-rolled MCP server speaking
  newline-delimited JSON-RPC 2.0 over stdio, with no SDK dependency.
  Six tools mirror the read surface: query_symbol, get_callers,
  get_callees, get_context_pack, map_status, refresh_map.
• The plugin ships an .mcp.json (with cwd set to
  ${CLAUDE_PROJECT_DIR}), so dekko --claude-install wires the server
  automatically.
• dekko --mcp-install registers the server for non-plugin setups via
  claude mcp add dekko -- dekko serve --mcp.

Changed

• Map regeneration was factored into a reusable regen_map helper so the
  server can force a full rebuild.

0.4.0 — 2026-06-12

Change-awareness and incremental mapping.

Added

• dekko diff [REV] — symbols added/removed/changed since a git rev
  (default: the commit the map was generated at), each with its impacted
  callers. Compares the working tree against git archive of the rev;
  "changed" means the symbol's source text differs. --limit, --json;
  exits 0 (no differences) / 1 (differences) / 2 (bad rev).
• A per-file extraction cache under .dekko/, keyed on the provenance
  content hash, so re-mapping only re-parses files whose contents
  changed. dekko map --full forces a cold rebuild.

Changed

• The first time the cache is written, .dekko/ is made self-ignoring
  and appended to the repository .gitignore.

0.3.0 — 2026-06-12

From a one-shot generator to a queryable context service.

Added

• A subcommand CLI: map, query, context, status. The v0.2 flags
  (--map, --claude-install, --version) keep working as aliases.
• dekko query — callers, callees, symbol, and file lookups
  against map.json, with exit codes 3 (not found) and 4 (ambiguous).
  Targets accept name, Class.method, or file.py:name.
• dekko context — a minimal signature neighborhood for editing a
  symbol, with --hops N and a --budget TOKENS trimmer.
• dekko status — freshness report from the provenance stamp; exits 0
  (fresh) / 1 (stale).
• map.json provenance (document version 2): tool version, git commit,
  discovery options, and per-file content hashes.
• Read commands auto-regenerate a stale map (--no-regen to opt out);
  dekko map --if-stale short-circuits when the map is already fresh.

0.2.0 — 2026-06-11

Packaged for distribution.

Changed

• Converted from a uv-run script into a pip-installable package:
  tool/ → src/dekko/, a hatchling build, and a dekko console
  script. Distributed on PyPI as dekko.
• The Claude Code plugin is embedded in the wheel and installed with
  dekko --claude-install.

Added

• --map [DIR] [SUBPATH], --output, --claude-install, and
  --version flags.
• A GitHub Actions release workflow using PyPI trusted publishing.

0.1.1 — 2026-06-11

Fixed

• /map permission failure caused by command substitution in the
  command preamble.
• A Python 3.11+ f-string that failed to compile on the declared 3.10
  floor.
• Repeated tree-sitter query recompilation (now cached), cutting a
  representative run from ~0.26s to ~0.17s.

Added

• A test that compiles every tool module against the declared Python
  floor.

0.1.0 — 2026-06-11

Initial release: the dekko Claude Code plugin.

Added

• A /map command that scans the repository with tree-sitter and writes
  MAP.md (files, functions, parameters with types, return types, and
  bidirectional call links) plus a machine-readable map.json — without
  spending model tokens on parsing.
• Tier-1 languages with full type fidelity (Python, Rust, C, C++,
  JavaScript, TypeScript/TSX, Go, Java) and a generic Tier-2 fallback for
  every other grammar in the language pack.
• Best-effort static call resolution (same container → same file →
  imports → unique repo-wide match); ambiguous calls are marked, never
  guessed.
