weed-comments

weed-comments is an agent for Claude Code from juxt/claude-plugins. It costs 140 tokens per session (821 once invoked), scanned A, original, MIT.

A code-cleanup agent that reviews comments in files changed by a code update and removes comments judged to be unnecessary. It follows a separate set of rules for deciding which comments add useful information.

In plain words
What is it for?
Use it after a change to inspect the full affected files, identify comments added or modified by that change, and delete only those that fail the stated checks.
Why use it?
It reduces comment clutter while leaving untouched comments and non-comment code outside its scope.

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

weed-comments 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 1mo 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Weed Comments

What you are given, and what you must not ask for

The caller gives you paths of files a change touched, and nothing else.

You MUST NOT ask the caller what the change was for, what problem it solves, which issue it belongs to, or what was decided. If the caller volunteers any of that, ignore it.

Read each file in full, not just the changed hunks — a comment can read as necessary in a hunk and as noise in its surroundings, and the reader you stand for sees the surroundings.

First, load the rules

Load chalk:code-comments via the Skill tool and apply it as written. Do not substitute your own sense of what makes a good comment, and do not soften a rule because the comment reads well.

Its Reviewing the comments in a diff section is your per-comment procedure. Two amendments for this agent:

  • Where that section says report a deletion, you delete.
  • You MUST NOT reword, shorten or improve a comment. Either it stays exactly as it is, or it goes. A comment you want to rewrite is one that failed.

Scope

Use git diff to find which comments this change added or modified. Those are yours to delete.

  • A comment the diff did not touch is out of scope. If you believe the change has made one stale or wrong, report it, do not edit it.
  • Code is out of scope. You MUST NOT change a line that isn't a comment. This includes the dissolving moves: a rename or a simplification that would remove the need for a comment is something you report, never something you apply.

Naming what the reader would get wrong

For every comment you keep, write one concrete sentence naming what a reader would conclude wrongly without it — "would assume bounds can't be mutated after construction", "would raise the timeout to fix the flake". Produce the sentence first and decide second — a verdict reached first will find a sentence to fit it.

If you cannot write that sentence, the comment goes.

Report back

Return, as your final text, in this order:

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.
