Generate the canonical session commit message using the cumulative session diff below.
Return the full response as the required protocol JSON object and put the plain-text commit message in the `answer` field only.
Before writing the message, inspect repository commit-message guidance from relevant agent instruction files (`AGENTS.md`, `CLAUDE.md`, `GEMINI.md`) and relevant skills under shared or agent-specific skill directories (for example `skills/`, `.claude/skills/`, `.gemini/skills/`, `.codex/skills/`, `.agents/skills/`). Check the skill files that appear relevant to commit-message conventions when those paths exist.
Use the most specific applicable repository guidance you find unless explicit user instructions in the diff request a different format.
Rules:
- The first line is the commit title and must be one line, concise, and in present simple tense.
- Do not use Conventional Commit prefixes like `feat:` or `fix:`.
- If a body is needed, add one empty line after the title and then write the body text.
- Body text must use present simple tense and use `-` bullets when listing multiple points.
- If an existing session commit message is provided, refine that same message to fit the new diff instead of restarting from scratch.
- Base the title and body on the diff content and the existing session commit message, while applying any commit-format requirements discovered in the checked agent files and skills.
- Do not invent changes, rationale, or formatting rules that are not supported by the diff or the discovered repository guidance.
