/describe

CRITICAL: This is a jj (Jujutsu) plugin. You MUST NOT use ANY raw git commands — not even for context discovery. This includes git checkout, git commit, git diff, git log, git status, git add, git branch, git remote, git rev-parse, git config, git show, git fetch, git pull, git push, git merge, git rebase, git stash, git reset, git tag, or any other git invocation. Do not run ls .git, git log, git remote -v or similar to detect repo state. Always use jj equivalents (jj log, jj status, jj diff, etc.). The only exceptions are jj git subcommands (e.g. jj git push, jj git fetch) and gh CLI for GitHub operations.

Context

• Current jj status: !jj status
• Changed files (JSON): !jj diff -T '"{ \"path\": " ++ self.path().display().escape_json() ++ ", \"status\": " ++ self.status().escape_json() ++ " }\n"'
• Change stats (JSON): !jj log -r @ --no-graph -T 'self.diff().stat().files().map(|entry| "{ \"path\": " ++ entry.path().display().escape_json() ++ ", \"lines_added\": " ++ entry.lines_added() ++ ", \"lines_removed\": " ++ entry.lines_removed() ++ ", \"bytes_delta\": " ++ entry.bytes_delta() ++ " }\n")'
• Current change (JSON): !jj log -r @ --no-graph -T 'json(self) ++ "\n"'
• Recent changes (JSON): !jj log --limit 10 --no-graph -T 'json(self) ++ "\n"'

Git → jj translation

Git	jj
git status	jj status
git diff HEAD	jj diff
git branch --show-current	jj log -r @ --no-graph
git log --oneline -10	jj log --limit 10

Your task

In jj, jj describe sets or updates the description of the current working copy change. Unlike jj commit, it does NOT finalize the change or start a new one — you stay on the same change with the same change ID.

Use cases:

• Label what you're currently working on
• Identify changes in anonymous branches (jj favors descriptions over bookmarks)
• Update the message before pushing

Based on the above changes, set an appropriate description on the current change:

jj describe -m "<msg>"

After describing, the change ID stays the same (only the commit ID changes). There is no staging in jj — the description applies to whatever is in the working copy.

You have the capability to call multiple tools in a single response. Set the description using a single message. Do not use any other tools or do anything else. Do not send any other text or messages besides these tool calls.
