dedupe

dedupe is a command for coding agents from coltonbearden/carrel. It costs 24 tokens per session (421 once invoked), scanned A, original, MIT.

A command that finds exact duplicate files by their contents and can also find similar-looking image copies.

In plain words
What is it for?
It helps report duplicate groups, choose which copy to keep, detect resized or re-encoded image duplicates, and optionally delete confirmed duplicates.
Why use it?
It identifies redundant files and shows possible space savings before anything is removed.

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.

agentmods
npx agentmods add commands/coltonbearden/carrel/dedupe
Clone the repo
git clone --depth 1 https://github.com/coltonbearden/carrel

Or install carrel-organize, the plugin that ships this one along with the rest of its 4 commands.

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

dedupe 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 today.

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.

What it actually says

Find duplicates in: $ARGUMENTS

Run the carrel CLI via Bash. First run carrel dedupe --help to confirm the exact flags available in the installed version, then map the user's request onto them — never invent flags. The expected interface is:

carrel --json dedupe DIR... [--near] [--delete newest|oldest] [--apply]

Note: --json is a global flag and must come before the subcommand.

  • Exact duplicates: BLAKE2b hash groups (size-prefiltered). --near: images only, perceptual dHash clustering (catches resized/re-encoded copies).
  • Report-only is the default — nothing is ever deleted without BOTH --delete <policy> AND --apply. Never pass --apply unless the user explicitly confirmed deletion after seeing the report; the kept member of each group is never deleted.

If carrel dedupe --help reports that the command does not exist, the installed carrel predates it — say so; you may fall back to comparing carrel inspect --json sha256 values for a small set of files, but do not guess flags.

Interpret the JSON [{hash, files, kept, deleted}]: show each duplicate group, which copy would be kept, and the reclaimable bytes. Then ask before any destructive re-run.

Requires the carrel CLI on PATH. If carrel is not found, tell the user to install it with uv tool install carrel (see the repo's INSTALL notes), or run it as uv run carrel ... from the carrel repo root.

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.
