returns even when nothing is staged. writes a tree from the index unconditionally — GitPython has no gate — and the return string cannot be false: An agent edits files, calls without (or after a that matched nothing), and gets a hash. It reports the work as committed. The working tree is still dirty, still holds the old content, and the repo now carries an empty commit. Nothing in the response distinguishes that from a real commit. itself refuses this: "no changes added to commit". Fix Raise when the index matches HEAD, matching git's default. Two cases git does allow are preserved: the first commit on an unborn branch, where there is no HEAD to compare against an empty merge commit, which git permits while exists — a conflict resolved back to HEAD's content leaves the index matching HEAD, and that commit is legitimate No new parameter: git requires explicitly, so refusing by default matches it. Tests Six, covering both directions. Three assert the refusal (unstaged edit, clean tree, untracked-only) and fail with the source change reverted. Three assert it does not over-refuse (staged deletion, unborn branch, empty merge commit) and pass either way. 53 passed in .

Describe the bug reports success when nothing is staged. It creates an empty commit and returns a hash, so a caller cannot tell it apart from a real commit. : writes a tree from the index unconditionally; GitPython has no gate. The return string cannot be false. The practical failure: an agent edits files, calls without — or after a whose paths matched nothing — and gets a hash back. It tells the user the work is committed. The working tree is still dirty, still holds the old content, and the repository now carries an empty commit. itself refuses this with "no changes added to commit". To Reproduce Expected behavior Refuse, as does without . Two cases git does permit and that should keep working: the first commit on an unborn branch, and an empty merge commit while is present. Additional context No test covers this; stages a file first. #4761 implements it.

Description Adds the TrueCalci deterministic calculation engine as a Streamable HTTP MCP server located at . TrueCalci provides 24 zero-hallucination mathematical and statutory calculation engines (Income tax brackets, mortgage PITI/PMI, contractor parity, compound schedules, and engineering formulas) executed at Cloudflare Edge. Server Details Server: TrueCalci Repository: https://github.com/truecalci-official/truecalci Homepage: https://truecalci.com Transport: Streamable HTTP () Engines**: 24 Deterministic Tools Motivation and Context AI models frequently hallucinate compound interest schedules, tax brackets, and floating-point math. TrueCalci provides deterministic, IEEE-754 precision math tools to prevent financial and arithmetic hallucinations in AI agents. How Has This Been Tested? Verified via JSON-RPC 2.0 handshake (, , ). Validated live on Claude Desktop and Cursor IDE over Streamable HTTP. Automated unit test suite passing locally and deployed to Cloudflare Edge.
