What is ase-repo-dissect?

A Git change decomposer that breaks a large staged change set into cohesive parts and creates a separate Git worktree for each part. A worktree is an additional working directory connected to the same repository.

Use it to split an epic or tangled change set into atomic parts when you want separately committable work.

It removes the manual effort of separating an oversized change into smaller pieces that can be reviewed or committed independently.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add rse/ase --skill ase-repo-dissect

Clone the repo

git clone --depth 1 https://github.com/rse/ase

Made for: Claude Code.

Or install ase, the plugin that ships this one along with the rest of its 57 skills, 10 agents, 5 hooks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00075	$0.04187
Opus 5.5	$0.00030	$0.01675
Sonnet 5.5	$0.00015	$0.00837

Security

Grade A, and why

ase-repo-dissect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Procedure

1. Determine the dissection hint: set , with any leading and trailing whitespace stripped. Additionally, inherit the always existing from the current context, as it names the worktrees and branches of all derived parts.
2. Determine the repository root by running the corresponding command (taken exactly as given) and capturing its output into :
  
  git rev-parse --show-toplevel
3. Determine the diff details and the diff statistics by running the corresponding commands (taken exactly as given) and capturing their full outputs into and :
  
  git diff --cached --numstat HEAD git diff
  
  git diff --numstat
4. git -C "<repo-root/>" -c core.quotepath=off ls-files --others --exclude-standard
  
  Skip every listed entry below the .ase/ directory -- it carries ASE's own state and the worktrees created by this very skill, and hence is never part of the user's change set.
  
  Then, for every remaining listed file, capture its creation diff by running the corresponding command (taken exactly as given) and append its output to :
  
  git -C "<repo-root/>" diff --no-index --binary /dev/null "<file/>"
  
  This command intentionally exits with a non-zero status, because the two compared paths differ; treat this exit status as success, not as an error. Judge the outcome by the output instead: a run which emits no diff on standard output but an error: or fatal: message (e.g. the entry is a nested Git repository, which git ls-files reports as a directory) is a real failure -- append nothing for that entry and only output the following , then continue with the next file:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ase-repo-dissect is a skill published in the GitHub repository rse/ase (60 stars, last pushed yesterday), licensed Apache-2.0. It adds 75 tokens to every session and 4,187 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-30.

verify

Pre-commit verification entry point. Claude Code 2.1.286+ instructs the model to run a skill named verify right before committing (docs-only and tests-only commits exempt); this thin wrapper delegates that call to the MoAI quality gate instead of hand-rolling substitute checks.
