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

branch-cleanup 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Perform a complete cleanup of local and remote branches after working on multiple PRs.

Current State

Default branch: !git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main"

Current branch: !git branch --show-current

Fetch latest: !git fetch --all --prune 2>&1

Branch Inventory

Local branches with tracking status:

!git branch --format='%(refname:short) %(upstream:track)' | sort

Recent branches by activity:

!git for-each-ref --count=15 --sort=-committerdate refs/heads/ --format='%(refname:short) - %(committerdate:relative)'

Remote branches:

!git branch -r --format='%(refname:short)' | grep -v HEAD | sort

Cleanup Candidates

Merged into default branch: !git branch --merged

Branches with gone remotes:

!git branch -vv | grep ': gone]' | awk '{print $1}' | sort

Protected Branches

Never delete branches matching these patterns:

  • main, master, develop, staging, production
  • release/* branches (unless explicitly confirmed)
  • renovate/* branches (managed by Renovate bot)
  • Current working branch
  • Branches with unpushed commits (confirm first)

Cleanup Workflow

Phase 1: Analyze

Review the branch inventory above. Categorize branches:

  • Safe to delete: Merged branches and branches with gone remotes (excluding protected)
  • Needs confirmation: release/* branches, branches with unpushed commits
  • Protected: All protected branch patterns and current branch

Phase 2: Confirm Cleanup Plan

Present the cleanup plan and ask the user to select scope:

  • All safe: Delete all merged and gone-remote branches
  • Merged only: Delete only branches merged into default
  • Gone only: Delete only branches with deleted remotes
  • Review each: Confirm each branch individually

If "Review each" is selected, iterate through candidates asking per-branch confirmation.

Phase 3: Execute Cleanup

After confirmation, execute in order:

  1. Prune stale remote-tracking refs: git remote prune origin
  2. Delete merged local branches: git branch -d <branch>
  3. Delete gone-remote branches: git branch -D <branch>

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.
