v0.4.0
d801e2f

Refreshes the built-in LLM model catalog for the latest provider releases: upgrades LangChain4j to 1.16.2 and adds the newest Anthropic (Claude Opus 4.8, Claude Fable 5), OpenAI (GPT-5.5 family), and Google (Gemini 3.5 Flash) models — 65 built-in models in total. You can now control reasoning depth on Anthropic's adaptive-thinking models via configurable effort levels. Also adds MCP tool annotations, ClojureDart (.cljd) support, and auto-correction of dash/underscore filename mismatches in path validation.

Major Changes

LangChain4j 1.16.2 Upgrade & New Models

  • Updated LangChain4j from 1.12.2 to 1.16.2 across all four artifacts (core, OpenAI, Anthropic, Google Gemini)
  • New Anthropic models: claude-opus-4-8, claude-opus-4-7, and claude-fable-5 (with reasoning variants). Aliases: :opus now resolves to Opus 4.8, plus :fable/:fable-5, :opus-4-8, :opus-4-7, and :opus-reasoning
  • New OpenAI models: GPT-5.5, GPT-5.5 Pro, GPT-5.4 Mini, and GPT-5.3 Codex. Aliases: :gpt-5-5, :gpt-5-5-pro, :gpt-5-4-mini, :gpt-5-3-codex, and :codex now resolves to GPT-5.5
  • New Google models: Gemini 3.5 Flash (:flash/:gemini-flash now resolve to it) and gemini-3.1-flash-lite
  • 65 total built-in models (up from 55)

Configurable Reasoning Effort for Anthropic Adaptive Thinking

  • Anthropic adaptive-thinking models (Opus 4.7+, Fable 5) accept a reasoning effort level via `{:thinking {:effort ...}}` — `:low`, `:medium`, `:high`, `:xhigh`, or `:max` (`:xhigh`/`:max` are Anthropic-only)
  • Adaptive-thinking models correctly omit sampling params (`:temperature`, `:top-p`, `:top-k`) and thinking `:budget-tokens`, which these models reject
  • Partial `:thinking` overrides now merge with model defaults instead of replacing them, so refining one key (e.g. `{:thinking {:effort :high}}`) preserves the rest of the configuration

Added

  • MCP tool annotations: Built-in tools now expose MCP `ToolAnnotations` (read-only / destructive / idempotent hints) so clients can present and gate tools more accurately
  • ClojureDart support: `.cljd` files are now recognized as Clojure files, with file-type detection consolidated across the codebase
  • `/release` slash command: Automates cutting a release — branch check, changelog update, version tag, push, and GitHub release

Changed

  • MCP Java SDK updated to 1.1.3
  • cljfmt upgraded from `0.13.1` to `0.16.4`. Unlocks new opt-in alignment options via `cljfmt.edn`. Defaults unchanged.
  • Breaking (cljfmt upstream, 0.16.0): cljfmt now ignores `.clj` config files by default. Rename `.cljfmt.clj` to `cljfmt.edn` or `.cljfmt.edn`.

Fixed

  • Path validation: File paths with dash/underscore mismatches are now auto-corrected (#48, #161)
