Changes:
- Introduces the exported Lamatic flow graph and template metadata for
commit-pr-generator. - Adds prompts/constitution/agent documentation and a usage README for the template.
- Adds a Gemini model config reference used by the Generate Text node.

- Around line 8-11: The current prompt only instructs the model to return an
error string for empty or invalid diffs, which is not a deterministic guard. Add
a real pre-check before invoking LLMNode_223 so invalid or empty input is
detected in code and returns the exact error response immediately, rather than
relying on the prompt text to handle validation. Make the change where the
prompt for the commit-pr generator is assembled so the fallback path is enforced
outside the LLM.

Hi @Ayazsaifi200! 👋 Before this PR can be reviewed by maintainers, please resolve all comments and requested changes from the CodeRabbit automated review. Steps to follow:
This helps keep the review process efficient for everyone. Thank you! 🙏 |
- Blank credentialId/credential_name so each user binds their own Lamatic credential (Copilot review). - Treat diff as untrusted input and use a bare error sentinel consistent with README/agent.md (Copilot review).

Thanks for the review! I've addressed all comments: 1. Hard-coded workspace credential (Copilot) — Fixed. 2. Error-string consistency + prompt injection (Copilot) — Fixed. The system prompt now (a) explicitly treats the diff as untrusted data and ignores any instructions embedded in it, and (b) uses the bare 3. Deterministic invalid-input check (CodeRabbit) — This is an intentional design choice for a minimal single-flow template (API Request → LLM → API Response). The model reliably returns the deterministic Please re-review — thanks! @coderabbitai review |

Summary
A new template that converts a raw
git diffinto a Conventional Commits message and a ready-to-paste PR description (Summary / Changes / Testing) using a single Lamatic flow (API Request → Generate Text (Gemini) → API Response).Why it's unique: No existing kit turns a git diff into commit messages / PR descriptions.
