Weigh in

2 things to look at

26 days oldThe repository was created 26 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Weigh an agent setup and print a fight-card receipt. Use when asked to weigh in, weigh my agent, check my agent's weight or token overhead, or compare before and after a cut. Measures the always-on context bill (installed skills, memory files, MCP tool schemas), assigns a weight class, prints a shareable card, and shows the delta against the last weigh-in. Read-only except for its own append-only log.

Weigh-In

The scale for your agent. skill-diet finds what to cut; weigh-in tells you what you weigh, before the cut and after it. Step on the scale first, cut, step on it again.

Method

Measure the always-on bill exactly as skill-diet does: installed skills (frontmatter name plus description each), memory files loaded at session start (CLAUDE.md, AGENTS.md, local variants, imports), MCP tool schemas (eager-loaded only; a server you cannot enumerate is unknown, never zero).
Rough tokens for English markdown: characters / 3 on Claude models with the Opus 4.7 tokenizer (Opus 4.7+, Sonnet 5, Fable 5), characters / 3.5 to 4 on older Claude and GPT-style tokenizers. Label estimates.
Read the last card from .cutweight/weigh-ins.md if it exists. Compute the delta.
Print the card. Append it to the log. Never edit old cards.

Weight Classes

Cutweight's own scale, by always-on tokens per message:

class	always-on
flyweight	under 1,000
lightweight	under 3,000
middleweight	under 8,000
heavyweight	under 20,000
superheavyweight	20,000 and up

The Card

cutweight weigh-in: 2026-07-10
always-on: 7,412 tokens on every message
  skills: 3,509 (27 installed)
  memory files: 3,903
  mcp schemas: ~0 (deferred loading)
class: middleweight
last weigh-in: 9,180 (-19%, was heavyweight)
next cut: the 25-skill plugin billing 2,462 for 4 skills used

Keep the card under 12 lines. It is made to be posted.

Hard Rules

The log is append-only. A rewritten history is not a weigh-in.
Measured or labeled-estimate numbers only.
The card always names the single next cut, or says "at weight" if lean.
Never name an agent-maintained memory file (auto-memory index, session memory) as the next cut. Bill it on the card, flag it to its owner. Its lines are the agent's retrieval keys; hand-trimming them breaks recall.
A card meant for posting shows counts and categories, never private tool, server, or plugin names. Generalize anything internal before it leaves the machine.
Keep .cutweight/ out of version control; the log stays on the machine.
Weigh-in changes nothing but its own log. The human does the cutting.
