sweep

sweep is a command for coding agents from cesarferreira/stax. It costs 0 tokens per session (909 once invoked), scanned A, original, MIT.

A command for reviewing local Git branches and optionally removing branches that are safe to delete. It groups branches as merged, removed from their remote, stale, or active.

In plain words
What is it for?
Use it to audit local branches, identify merged or abandoned work, and explicitly delete branches that no longer need to be kept.
Why use it?
It shows what old branches are accumulating while protecting the main branch, the current branch, and branches that still contain unique work.

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.

Security

Grade A, and why

sweep 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 6d 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.

stax sweep

Classify all local branches and optionally delete the safe-to-remove ones.

Why sweep?

Over time a repo accumulates branches that were merged, whose PR was closed, or that were abandoned as work-in-progress. stax sync already cleans up stax-tracked merged branches during rs, but it ignores untracked branches and has no read-only listing mode.

stax sweep fills both gaps:

  • Operates on every local branch (tracked and untracked).
  • Lists branches grouped by status so you can see what's accumulating.
  • Deletes only what you explicitly ask for, never touching trunk or the current branch.

Branch statuses

Status Meaning
merged Ancestor of trunk, PR metadata says merged, or a stax-tracked PR branch has a deleted upstream
upstream-gone Remote tracking ref is [gone] and the branch has no commits unique to local or remote trunk
stale Last commit older than the configured threshold (default 30 days)
active Everything else

Precedence when a branch matches multiple: merged > safe upstream-gone > stale > active. Ordinary upstream-gone branches with unique commits are treated as active so cleanup cannot delete local-only work.

Usage

# Read-only: classify all local branches and print a grouped summary
stax sweep

# Delete merged branches and upstream-gone branches with no unique work, with confirmation
# Stax-tracked PR branches are also merged when PR metadata says merged or the upstream was deleted
stax sweep --delete

# Also include stale branches in the deletion set
stax sweep --delete --include-stale

# Skip the confirmation prompt
stax sweep --delete --force

# Override the stale threshold
stax sweep --stale-days 60

# Machine-readable output (conflicts with --delete)
stax sweep --json

Flags

Flag Description
--delete Delete merged branches, tracked merged PR branches, and upstream-gone branches with no unique work after confirmation
--include-stale Extend deletion to stale branches (requires --delete)
--force Skip confirmation prompt (requires --delete)
--stale-days <N> Override stale threshold in days (default: 30)
--json Output classification as JSON; conflicts with --delete

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.

sweep is a command published in the GitHub repository cesarferreira/stax (124 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 909 tokens. 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 2026-08-30.
