tidy

A cleanup command for deleting old code-review run folders stored in .lookagain/.

In plain words
What is it for?
Use it to retain runs from the last chosen number of days or remove all stored runs, including today's, when explicitly requested.
Why use it?
It keeps review results from accumulating while preserving recent runs by default.

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.

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 C, and why

tidy scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it actually says

Tidy Old Review Runs

You are cleaning up old review results from .lookagain/.

Parse arguments

The user may pass key=value pairs after the command name. The raw argument string is:

$ARGUMENTS

If the argument string is empty or blank, the user provided no overrides — use all defaults. Parse key=value pairs from the string. For any key not provided, use the default.

Key Default Description
keep 1 Keep runs from the last N days
all false Remove all runs including today's (true or false)

Process

  1. Use Glob to list all directories under .lookagain/ matching the pattern .lookagain/????-??-??T??-??-??/.

  2. If no run directories exist, tell the user there's nothing to tidy and stop.

  3. Determine which runs to remove:

    • If the resolved all value is true, remove ALL run directories.
    • Otherwise, calculate the cutoff date by subtracting the resolved keep value (in days) from today's date. Remove only run directories whose date portion (the YYYY-MM-DD prefix of the directory name) is strictly before the cutoff date.
  4. Before deleting, validate each directory name matches the exact pattern YYYY-MM-DDTHH-MM-SS (all digits in the right positions). Skip any directory that doesn't match.

  5. For each validated run directory to remove, use Bash to delete it: rm -rf .lookagain/<run-id>

  6. Report what was done:

## Tidy Complete

Removed N run(s): <list of run-ids removed>
Kept M run(s): <list of run-ids kept>

If nothing was removed, say so:

## Nothing to Tidy

All N run(s) are within the keep window.
Changes

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.

tidy is a command published in the GitHub repository HartBrook/lookagain (10 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 463 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
