rclone_check

rclone_check is a command for coding agents from chaunsin/agent-skills. It costs 10 tokens per session (1,473 once invoked), scanned A, original, Apache-2.0.

A command for comparing files in two storage locations. It checks file sizes and, when available, hashes—short fingerprints used to detect changed contents—without changing either location.

In plain words
What is it for?
Use it for quick size checks, hash checks, one-way comparisons, or full comparisons that download data when remote hashes are unavailable.
Why use it?
It reveals missing, extra, or different files so you can verify a copy or backup.

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

rclone_check 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 3d 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.

rclone check

Checks the files in the source and destination match.

Synopsis

Checks the files in the source and destination match. It compares sizes and hashes (MD5 or SHA1) and logs a report of files that don't match. It doesn't alter the source or destination.

For the crypt remote there is a dedicated command, cryptcheck, that are able to check the checksums of the encrypted files.

If you supply the --size-only flag, it will only compare the sizes not the hashes as well. Use this for a quick check.

If you supply the --download flag, it will download the data from both remotes and check them against each other on the fly. This can be useful for remotes that don't support hashes or if you really want to check all the data.

If you supply the --checkfile HASH flag with a valid hash name, the source:path must point to a text file in the SUM format.

If you supply the --one-way flag, it will only check that files in the source match the files in the destination, not the other way around. This means that extra files in the destination that are not in the source will not be detected.

The --differ, --missing-on-dst, --missing-on-src, --match and --error flags write paths, one per line, to the file name (or stdout if it is -) supplied. What they write is described in the help below. For example --differ will write all paths which are present on both the source and destination but different.

The --combined flag will write a file (or stdout) which contains all file paths with a symbol and then a space and then the path to tell you what happened to it. These are reminiscent of diff files.

  • = path means path was found in source and destination and was identical
  • - path means path was missing on the source, so only in the destination
  • + path means path was missing on the destination, so only in the source
  • * path means path was present in source and destination but different.
  • ! path means there was an error reading or hashing the source or dest.

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.

rclone_check is a command published in the GitHub repository chaunsin/agent-skills (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 10 tokens to every session and 1,473 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
