Stack Reorganize

What it does

When your agent uses it

• Its commits are hard to review
• Have an awkward shape - my stack is hard to review
• Clean up these commits
• Organize my patches for review

Example prompts

• “my stack is hard to review”
• “clean up these commits”
• “organize my patches for review”
• “/stack-reorganize”

Requirements

• A Bash shell
• Pre-approved tools (allowed-tools): Bash(git log:*), Bash(git show:*), Bash(git blame:*), Bash(git add:*), Bash(git diff:*), Bash(git status:*), Bash(git branch:*), Bash(git checkout:*), Bash(git restore:*), Bash(git commit:*), Bash(git cherry-pick:*), Bash(git rebase:*), Bash(git reset:*), Bash(git rev-list:*), Bash(git ls-tree:*), Bash(git apply:*), Bash(git range-diff:*), Bash(git patch-id:*), Bash(git grep:*), Bash(git cat-file:*), Bash(git rev-parse:*), Bash(grep:*), Bash(awk:*), Bash(sort:*), Bash(tr:*), Bash(bash .claude/skills/stack-reorganize/scripts/git-churn.sh:*), Bash(bash .agents/skills/stack-reorganize/scripts/git-churn.sh:*), Bash(jj log:*), Bash(jj show:*), Bash(jj diff:*), Bash(jj st:*), Bash(jj op:*), Bash(jj squash:*), Bash(jj commit:*), Bash(jj new:*), Bash(jj describe:*), Bash(jj rebase:*), Bash(jj edit:*), Bash(jj abandon:*), Bash(jj absorb:*), Bash(jj fix:*), Bash(jj restore:*), Bash(jj file show:*), Read, Grep, Glob

What it can do on your machine

Read from SKILL.md and the folder at commit 59c8a94. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(git log:*)
  • Bash(git show:*)
  • Bash(git blame:*)
  • Bash(git add:*)
  • Bash(git diff:*)
  • Bash(git status:*)
  • Bash(git branch:*)
  • Bash(git checkout:*)
  • Bash(git restore:*)
  • Bash(git commit:*)

  …and 36 more on the same allowed-tools line.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Shell), which the agent can run.

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Stack Reorganize loads about 5.4k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 93 tokens; SKILL.md has 3,304 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~93

When it runs · the whole SKILL.md, loaded when a task matches

~5.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~17k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,304 words (~5,433 tokens).
